Care related pain in rehabilitation after orthopedic trauma: An exploratory study with qualitative data.

OBJECTIVE: Care related pain (CRP) is generally under-estimated and rarely studied in rehabilitation as well as in general medecine. Beliefs about pain influence psychological distress, adjustment to pain and physical disability. In this sense, perceptions of CRP could limit recovery. This exploratory study aims to understand patients' and caregivers' subjective perceptions and beliefs about CRP. PATIENTS AND METHODS: Questionnaires about CRP were submitted to members of the interdisciplinary team of a rehabilitation hospital and to patients with musculoskeletal complaints (cross-sectional design). Twenty patients were also individually interviewed (qualitative data). Four topics were addressed: frequency of CRP, situations and procedures causing CRP, beliefs about CRP and means used to deal with CRP. RESULTS: Seventy-five caregivers and 50 patients replied to the questionnaire. CRP is a very common experience in rehabilitation and it is recognized by both groups. Generally, the situations causing CRP reflect the specificity of rehabilitation (mobilization...) and are similarly perceived by patients and caregivers, with patients considering them as more painful. Beliefs about CRP are clearly different from those usually associated with pain. Both groups point out the utilitarian and the inevitable character of CRP. They differ on that, that patients had a more positive view about CRP. They associate it more often with progress and see it as acceptable at least until a certain limit. They are also able to perceive the richness of means used by physiotherapists to help them coping with CRP. CONCLUSION: Our data may suggest new keys to motivate patient to be active in rehabilitation for example in choosing carefully arguments or words which may fit theirs' beliefs about CRP, or in using various means to manage CRP. Promoting the use of relational competences with chronic pain patients and of a patient-centred approach may also be a concern in training caregivers.

Progress of soybean charcoal rot under tillage and no-tillage systems in Brazil

The increase in incidence of charcoal rot caused by Macrophomina phaseolina on soybeans (Glycine max) was followed four seasons in conventional and no-till cropping systems. In the 1997/98 and 2000/01 seasons, total precipitation between sowing and harvest reached 876.3 and 846.9 mm, respectively. For these seasons, disease incidence did not differ significantly between the no-till and conventional systems. In 1998/99 and 1999/00 precipitation totaled 689.9 and 478.3 mm, respectively. In 1998/99, in the no-till system, the disease incidence was 43.7% and 53.1% in the conventional system. In 1999/00 the final incidence was 68.7% and 81.2% for the no-till and conventional systems, respectively. For these two seasons, precipitation was lower than that required for soybean crops (840 mm), and the averages of disease incidence were significantly higher in the conventional system. The concentration of microsclerotia in soil samples was higher in samples collected in conventional system at 0 - 10 cm depth. However, analysis of microsclerotia in roots showed that in years with adequate rain no difference was detected. In dry years, however, roots from plants developed under the conventional system had significantly more microsclerotia. Because of the wide host range of M. phaseolina and the long survival times of the microsclerotia, crop rotation would probably have little benefit in reducing charcoal rot. Under these study conditions it may be a better alternative to suppress charcoal rot by using the no-till cropping system to conserve soil moisture and reduce disease progress.

Progress of Asian soybean rust and airborne urediniospores of Phakopsora pachyrhizi in southern Brazil

Asian soybean rust, caused by the fungus Phakopsora pachyrhizi, was reported at epidemic levels in 2003/2004 and is the main soybean disease in Brazil. The aim of this study was to investigate the spread of Asian soybean rust and to quantify airborne urediniospores in the region of Campo Mourão, Paraná State, Brazil. Three experiments were conducted under field conditions during the 2007/08 and 2008/09 crop seasons. Using the disease gradient method, provided by the application of increasing levels of the fungicide tebuconazole, four Asian soybean rust epidemics at different intensities were obtained in each experiment. To quantify the urediniospores, weathercock-type spore collectors were installed during and between the two crop seasons. Disease progress curves were plotted for each epidemic, and maximum severity was estimated. The curves were fit to the logistic model, which provided higher coefficients of determination and more randomly distributed residuals plotted over time. Analyses of the area under the disease progress curve showed that the largest epidemics occurred in the 2007/2008 crop season and that the progress rates were higher for severity, even among plants protected with the fungicide. The number of urediniospores collected in the air was related to the presence of soybean plants in the cultivated crops. The quantity of urediniospores was also positively correlated to the disease severity and incidence, as well as to cumulative rainfall and favorable days for P. Pachyrhizi infection.

Mild Cognitive Impairment and Early Detection of Alzheimer`s Disease. A Positron Emission Tomography Study

Alzheimer`s disease (AD) is characterised neuropathologically by the presence of extracellular amyloid plaques, intraneuronal neurofibrillary tangles, and cerebral neuronal loss. The pathological changes in AD are believed to start even decades before clinical symptoms are detectable. AD gradually affects episodic memory, cognition, behaviour and the ability to perform everyday activities. Mild cognitive impairment (MCI) represents a transitional state between normal aging and dementia disorders, especially AD. The predictive accuracy of the current and commonly used MCI criteria devide this disorder into amnestic (aMCI) and non-amnestic (naMCI) MCI. It seems that many individuals with aMCI tend to convert to AD. However many MCI individuals will remain stable and some may even recover. At present, the principal drugs for the treatment of AD provide only symptomatic and palliative benefits. Safe and effective mechanism-based therapies are needed for this devastating neurodegenerative disease of later life. In conjunction with the development of new therapeutic drugs, tools for early detection of AD would be important. In future one of the challenges will be to detect at an early stage these MCI individuals who will convert to AD. Methods which can predict which MCI subjects will convert to AD will be much more important if the new drug candidates prove to have disease-arresting or even disease–slowing effects. These types of drugs are likely to have the best efficacy if administered in the early or even in the presymptomatic phase of the disease when the synaptic and neuronal loss has not become too widespread. There is no clinical method to determine with certainly which MCI individuals will progress to AD. However there are several methods which have been suggested as predictors of conversion to AD, e.g. increased [11C] PIB uptake, hippocampal atrophy in MRI, low CSF A beta 42 level, high CSF tau-protein level, apolipoprotein E (APOE) ε4 allele and impairment in episodic memory and executive functions. In the present study subjects with MCI appear to have significantly higher [¹¹C] PIB uptake vs healthy elderly in several brain areas including frontal cortex, the posterior cingulate, the parietal and lateral temporal cortices, putamen and caudate. Also results from this PET study indicate that over time, MCI subjects who display increased [¹¹C] PIB uptake appear to be significantly more likely to convert to AD than MCI subjects with negative [¹¹C] PIB retention. Also hippocampal atrophy seems to increase in MCI individuals clearly during the conversion to AD. In this study [¹¹C] PIB uptake increases early and changes relatively little during the AD process whereas there is progressive hippocampal atrophy during the disease. In addition to increased [¹¹C] PIB retention and hippocampal atrophy, the status of APOE ε4 allele might contribute to the conversion from MCI to AD.

Conventional and novel cardiovascular risk factors in young Finns and their associations with structural and functional vascular changes of subclinical atherosclerosis. The Cardiovascular Risk in Young Finns Study

Background: Atherosclerosis begins in early life progressing from asymptomatic to symptomatic as we age. Although substantial progress has been made in identifying the determinants of atherosclerosis in middle to older age adults at increased cardiovascular risk, there is lack of data examining determinants and prediction of atherosclerosis in young adults. Aims: The current study was designed to investigate levels of cardiovascular risk factors in young adults, subclinical measures of atherosclerosis, and prediction of subclinical arterial changes with conventional risk factor measures and novel metabolic profiling of serum samples. Subjects and Methods: This thesis utilised data from the follow-ups performed in 2001 and 2007 in the Cardiovascular Risk in Young Finns study, a Finnish population-based prospective cohort study that examined 2,204 subjects who were aged 30-45 years in 2007. Subclinical atherosclerosis was studied using noninvasive ultrasound measurements of carotid intima-media thickness (IMT), carotid arterial distensibility (CDist) and brachial flow-mediated dilation (FMD). Measurements included conventional risk factors and metabolic profiling using highthroughput nuclear magnetic resonance (NMR) methods that provided data on 42 lipid markers and 16 circulating metabolites. Results: Trends in lipids were favourable between 2001 and 2007, whereas waist circumference, fasting glucose, and blood pressure levels increased. To study the stability of noninvasive ultrasound markers, 6-year tracking (the likelihood to maintain the original fractile over time) in 6 years was examined. IMT tracked more strongly than CDist and FMD. Cardiovascular risk scores (Framingham, SCORE, Finrisk, Reynolds and PROCAM) predicted subclinical atherosclerosis equally. Lipoprotein subclass testing did not improve the prediction of subclinical atherosclerosis over and above conventional risk factors. However, circulating metabolites improved risk stratification. Tyrosine and docosahexaenoic acid were found to be novel biomarkers of high IMT. Conclusions: Prediction of cardiovascular risk in young Finnish adults can be performed with any of the existing risk scores. The addition of metabonomics to risk stratification improves prediction of subclinical changes and enables more accurate targeting of prevention at an early stage.

Modeling study of limestone reactions in fluidized bed conditions

Traditionally limestone has been used for the flue gas desulfurization in fluidized bed combustion. Recently, several studies have been carried out to examine the use of limestone in applications which enable the removal of carbon dioxide from the combustion gases, such as calcium looping technology and oxy-fuel combustion. In these processes interlinked limestone reactions occur but the reaction mechanisms and kinetics are not yet fully understood. To examine these phenomena, analytical and numerical models have been created. In this work, the limestone reactions were studied with aid of one-dimensional numerical particle model. The model describes a single limestone particle in the process as a function of time, the progress of the reactions and the mass and energy transfer in the particle. The model-based results were compared with experimental laboratory scale BFB results. It was observed that by increasing the temperature from 850 °C to 950 °C the calcination was enhanced but the sulfate conversion was no more improved. A higher sulfur dioxide concentration accelerated the sulfation reaction and based on the modeling, the sulfation is first order with respect to SO2. The reaction order of O2 seems to become zero at high oxygen concentrations.

The Progress and Challenges of the e-Government Initiatives and Implementation in the Kurdistan Region of Iraq

The Electronic Government (e-Government) means delivering the services and information to the citizens and businesses through the use of Information and Communication Technology (ICT) in order to enable them to interact more effectively with the government, and to increase the quality of the services. As many other governments in the developed and developing countries, the Kurdistan Regional Government (KRG) has embarked on the e-Government initiatives. This study revealed that there are various challenges which affect the e-Government in the Kurdistan Region of Iraq (KRI), but also a lot of e-Government progress has happened. In addition, based on the United Nations’ e-Government maturity level benchmarking, the e-Government in the KRI is at the interactive stage. In this study the services that the citizens want from the government in order to implement an appropriate e-Government were also identified.

ESTABLISH & DEPLOY DOWNSTREAM MARKETING CAPABILITIES: a case study research following the framework implementation journey

According to many academic researches, the development of marketing capabilities can enhance organizational performance. Similarly, downstream marketing capabilities have an important role in accomplishment the organizational goals. Particularly the downstream marketing capabilities identified in this research are the Marketing Communication, Selling, Marketing implementation, and Market information management. These four capabilities are summarized under the following abilities. First, the ability to manage customers’ opinion regarding the offered value from the organization. Second, the ability of the organization to obtain orders from new and established customers. Third, the ability of aligning and translate the marketing strategy into an operating action plan along with the deployment of the organizational resources. Forth, the continuous process of gathering and managing information about the markets. Moreover, the literature review of this research shed light on the elements that compose the downstream marketing capabilities. Specifically, this research examined the downstream processes and the required information required to control these processes based on the American Productivity and Quality Center’s Process Classification Framework. Furthermore, the literature review examined some of the technological tools that are used in marketing processes, and also some managerial implication regarding the management of the downstream marketing employees. Along with the investigation of downstream marketing capabilities, the literature review investigated the utilization and the benefits of Component Business Model and Process Classification Framework, as they are defined by the organizations that developed them. Besides this initial study, the research presents how the examined organization is using the two frameworks together by cross-referring them. Finally, the research presents the optimal deployment of the collected downstream capabilities elements in the current organizational structure. The optimal deployment has been grounded on the information collected from the literature review but also from internal documentation, provided from the examined organization. By comparing the optimal deployment and the current condition on the organization, the research exhibits some points for improvement, but also some of the projects that are currently in progress inside the organization and eventually will provide solutions to these downsides.

Neuropsychological rehabilitation of memory deficits and activities of daily living in patients with Alzheimer's disease: a pilot study

Patients with Alzheimer's disease (AD) gradually lose their cognitive competence, particularly memory, and the ability to perform daily life tasks. Neuropsychological rehabilitation is used to improve cognitive functions by facilitating memory performance through the use of external aids and internal strategies. The effect of neuropsychological rehabilitation through memory training - motor movements, verbal association, and categorization - and activities of daily living (ADL) training was tested in a sample of 5 elderly out-patients (mean age: 77.4 ± 2.88 years), with mild AD (Mini-Mental State Examination score: 22.20 ± 2.17) and their caregivers. All patients had been taking rivastigmine (6-12 mg/day) for at least 3 months before being assigned to the rehabilitation sessions, and they continued to take the medication during the whole program. Just before and after the 14-week neuropsychological rehabilitation program all patients were assessed by interviewers that did not participate in the cognitive training, using the Mini-Mental State Examination, Montgomery-Alsberg Depression Rating Scale, Hamilton Anxiety Scale, Interview to Determine Deterioration in Functioning in Dementia, Functional Test, Memory Questionnaire of Daily Living for patient and caregiver, Quality of Life Questionnaire for patient and caregiver, and a neuropsychological battery. The results showed a statistically significant improvement in ADL measured by Functional Test (P = 0.04), and only a small improvement in memory and psychiatric symptoms. Our results support the view that weekly stimulation of memory and training of ADL is believed to be of great value in AD treatment, not only delaying the progress of the disease, but also improving some cognitive functions and ADL, even though AD is a progressively degenerative disease.

A case study of a high functioning autistic female in a games setting

This study detennined whether or not a high functioning autistic girl can develop game structure strategies that may allow her to become an active participant in a game or sport environment. This qualitative case study involved the in-depth observation and description of one high functioning autistic student whose experience in a game setting would be studied. The type of case study carried out was a combination of descriptive and evaluative. This experience was investigated through structured, individual programming. Through on-site observation, journal entries, and hands on instruction, I was able to describe what progress the autistic student made in tenns of skill development. The results of the study demonstrated that a high-functioning autistic female has the potential to develop the necessary motor skills to participate in the chosen sport of basketball. The observation results and field notes contributed to a movement profile which described her habits of body. Teaching strategies and frameworks utilized during the study were described and listed. Insights and commentary are further provided. A thorough examination of autism and games programming is provided in the literature review.

The role of a minor party : a comparative study of the British Liberal Party and the Australian Country Party since 1918

and the Australian Country Party since 1918. 2. The thesis examines the proposition that the role of a minor party is determined, not by its total strength expressed as a percentage of the national vote, but by how its strength is concentrated. Australia and Britain were chosen for the comparison because of the many similarities in political culture and in the extent of class voting. Each country has a party - the Country Party in Australia and the Liberal Party in Britain - which has had a distinct impact on the political scene in their respective countries. In the period from 1918 to the present day neither party, at the national level, has ever held the largest number of seats in parliament let alone a majority of seats, and it is in this sense that they are herein defined as minor parties. In the thesis the constitutional background of and differences between Australia and Britain are reviewed, followed by a brief historical picture of each of the two parties being studied. The sources of supporc of the two parties are analysed and it is here that real differences emerge. The Country Party in Australia is a deliberately sectional party with a narrow rural base, whereas the British Liberal Party is more broadly based than either the Labour or Conservative Parties in Britain. 3. Party leadership and organisation are then discussed. Both parties have had outstanding leaders, Earle Page and McEwen for the Country Party; Asquith, Lloyd George and Grimond for the Liberal Party. Both parties have had relatively fewer leaders than their major party opponents. However, whereas the Country Party has been free of serious splits the Liberal Party was shattered on the leadership struggles of Asquith and Lloyd George. Both parties have been identified with decentralisation of state power, the Country Party through its support, albeit sometimes lukewarm of the New States Movement; the Liberal Party through its espousal of a federal system for Britain with separate Welsh, Scottish and regional assemblies. Unfortunately for the British Liberal Party the beneficiaries of their policies in this area have been relatively new nationalist parties in both Wales arid Scotland. The major part of the thesis is devoted to a study of how the electoral systems in the two countries have, in practice, worked to the advantage or disadvantage of the Country Party and the British Liberal Party. The Country Party has been as consistently over-represented in the House of Representatives as the Liberal Party has been under-represented in the British House of Commons. With the even distribution of its support the introduction of the single transferable vote, in itself, would bring little benefit to the British Liberal Party in terms of seats. Multimember urban constituencies combined with some type of list system are the only way the Liberals are likely to obtain House of Commons seats in proportion to their votes. 4. Finally, the relations of the two minor parties with their respective major parties are considered. In the conclusion the future of the two parties is reviewed. In general terms it appears that the Country Party is faced with a slow decline. Although the British Liberal Party made a major breakthrough, in terms of votes, in the February 1974 election, they were unable to maintain this momentum in the October election, even though they lost very little ground. In the long term they must make an inroad into Labour held seats if they are to progress further.

Understanding Network Governance: A Case Study Exploration of Active Canada 20/20

Consistent with the governance shift towards network forms of governance, a number of new social movements have formed in response to the declining levels of physical activity in the Western world. One such movement is Active Canada 20/20: A Physical Activity Strategy and Change Agenda for Canada. Network governance is employed as the theoretical framework for this case study exploration of Active Canada 20/20 and the political landscape surrounding its development and implementation. Semi-structured interviews were conducted in addition to document/policy analysis and direct observations. Analysis of the data resulted in three overarching themes – the defining characteristics of network governance, the political landscape, and intersectoral linkages – that interconnect multifariously based the nature of the Canadian federal government and its relationship with the voluntary sector for physical activity. Despite progress in driving Active Canada 20/20 forward, entrenched dynamics of power need to be navigated within the political landscape surrounding network governance.

Immuno-oncology of human prostate cancer : phenotypical characterization and study of the tumor-derived, androgen-regulated immunosuppressive microenvironment

Le cancer de la prostate est le cancer le plus fréquemment diagnostiqué chez les hommes canadiens et la troisième cause de décès relié au cancer. Lorsque diagnostiqué à un stade précoce de la maladie, le cancer de la prostate est traité de manière curative par chirurgie et radiothérapie. Par contre, les thérapies actuelles ne peuvent éradiquer la maladie lorsqu’elle progresse à des stades avancés. Ces thérapies, comme la chimiothérapie et l’hormonothérapie, demeurent donc palliatives. Il est primordial d’optimiser de nouvelles thérapies visant l’élimination des cellules cancéreuses chez les patients atteints des stades avancés de la maladie. Une de ces nouvelles options thérapeutiques est l’immunothérapie. L’immunothérapie du cancer a fait des progrès considérables durant les dernières années. Cependant, les avancements encourageants obtenus lors d’essais précliniques ne se sont pas encore traduits en des résultats cliniques significatifs. En ce qui concerne le cancer de la prostate, les résultats négligeables suivants des interventions immunothérapeutiques peuvent être causés par le fait que la plupart des études sur le microenvironnement immunologique furent effectuées chez des modèles animaux. De plus la majorité des études sur l’immunologie tumorale humaine furent effectuées chez des patients atteints d’autres cancers, tels que le mélanome, et non chez les patients atteints du cancer de la prostate. Donc, le but central de cette thèse de doctorat est d’étudier le microenvironnement immunologique chez les patients atteints du cancer de la prostate afin de mieux définir les impacts de la tumeur sur le développement de la réponse immunitaire antitumorale. Pour réaliser ce projet, nous avons établi deux principaux objectifs de travail : (i) la caractérisation précise des populations des cellules immunitaires infiltrant la tumeur primaire et les ganglions métastatiques chez les patients atteints du cancer de la prostate; (ii) l’identification et l’étude des mécanismes immunosuppressifs exprimés par les cellules cancéreuses de la prostate. Les résultats présentés dans cette thèse démontrent que la progression du cancer de la prostate est associée au développement d’un microenvironnement immunosuppressif qui, en partie, est régulé par la présence des androgènes. L’étude initiale avait comme but la caractérisation du microenvironnement immunologique des ganglions drainant la tumeur chez des patients du cancer de la prostate. Les résultats présentés dans le chapitre III nous a permis de démontrer que les ganglions métastatiques comportent des signes cellulaires et histopathologiques associés à une faible réactivité immunologique. Cette immunosuppression ganglionnaire semble dépendre de la présence des cellules métastatiques puisque des différences immunologiques notables existent entre les ganglions non-métastatiques et métastatiques chez un même patient. La progression du cancer de la prostate semble donc associée au développement d’une immunosuppression affectant les ganglions drainant la tumeur primaire. Par la suite, nous nous sommes intéressés à l’impact de la thérapie par déplétion des androgènes (TDA) sur le microenvironnement immunologique de la tumeur primaire. La TDA est associée à une augmentation marquée de l’inflammation prostatique. De plus, les protocoles d’immunothérapies pour le cancer de la prostate actuellement évalués en phase clinique sont dirigés aux patients hormonoréfractaires ayant subi et échoué la thérapie. Cependant, peu d’information existe sur la nature de l’infiltrat de cellules immunes chez les patients castrés. Il est donc essentiel de connaître la nature de cet infiltrat afin de savoir si celui-ci peut répondre de manière favorable à une intervention immunothérapeutique. Dans le chapitre IV, je présente les résultats sur l’abondance des cellules immunes infiltrant la tumeur primaire suivant la TDA. Chez les patients castrés, les densités de lymphocytes T CD3+ et CD8+ ainsi que des macrophages CD68+ sont plus importantes que chez les patients contrôles. Nous avons également observé une corrélation entre la densité de cellules NK et une diminution du risque de progression de la maladie (rechute biochimique). Inversement, une forte infiltration de macrophages est associée à un plus haut risque de progression. Conjointement, durant cette étude, nous avons développé une nouvelle approche informatisée permettant la standardisation de la quantification de l’infiltrat de cellules immunes dans les échantillons pathologiques. Cette approche facilitera la comparaison d’études indépendantes sur la densité de l’infiltrat immun. Ces résultats nous ont donc permis de confirmer que les effets pro-inflammatoires de la TDA chez les patients du cancer de la prostate ciblaient spécifiquement les lymphocytes T et les macrophages. L’hypothèse intéressante découlant de cette étude est que les androgènes pourraient réguler l’expression de mécanismes immunosuppressifs dans la tumeur primaire. Dans le chapitre V, nous avons donc étudié l’expression de mécanismes immunosuppressifs par les cellules cancéreuses du cancer de la prostate ainsi que leur régulation par les androgènes. Notre analyse démontre que les androgènes augmentent l’expression de molécules à propriétés immunosuppressives telles que l’arginase I et l’arginase II. Cette surexpression dépend de l’activité du récepteur aux androgènes. Chez les patients castrés, l’expression de l’arginase II était diminuée suggérant une régulation androgénique in vivo. Nous avons observé que l’arginase I et l’arginase II participent à la prolifération des cellules du cancer de la prostate ainsi qu’à leur potentiel immunosuppressif. Finalement, nous avons découvert que l’expression de l’interleukin-8 était aussi régulée par les androgènes. De plus, l’interleukin-8, indépendamment des androgènes, augmente l’expression de l’arginase II. Ces résultats confirment que les androgènes participent au développement d’une microenvironnement immunosuppressif dans le cancer de la prostate en régulant l’expression de l’arginase I, l’arginase II et l’interleukin-8. En conclusion, les résultats présentés dans cette thèse témoignent du caractère unique du microenvironnement immunologique chez les patients atteints du cancer de la prostate. Nos travaux ont également permis d’établir de nouvelles techniques basées sur des logiciels d’analyse d’image afin de mieux comprendre le dialogue entre la tumeur et le système immunitaire chez les patients. Approfondir les connaissances sur les mécanismes de régulation du microenvironnement immunologique chez les patients atteint du cancer de la prostate permettra d’optimiser des immunothérapies mieux adaptées à éradiquer cette maladie.

A Study on the Use of Castor Oil as Plasticizer in Natural Rubber Compounds

Mechanical properties and thermal degradation of natural rubber compounds containing castor oil were studied to evaluate its suitability as plasticizer. Naphthenic oil was used as a reference plasticizer. The cure time was marginally lower in the case of castor oil mixes, probably due to the presence offree fatty acids in it. The tear strength and modulus were better in the case of mixes containing castor oil, while most of the other mechanical properties were comparable to the mixes containing naphthenic oil. The heat build up and compression set were higher than that of the naphthenic oil mixes. Thermal studies showed an increase of 8 °C in the temperature of initiation of degradation and an increase of 6 °C in the temperature at which the peak rate of degradation occurred. The peak rate of degradation was comparable to that of the reference compound
