Individuell livskvalitet hos patienter i psykiatrisk vård : En pilotstudieWågström, Kajsa, Lambrou, Katarina January 2016 (has links)
Bakgrund: Individer med psykisk sjukdom har sämre hälsa och ökad dödlighet i somatiska sjukdomar jämfört med befolkningen i övrigt. Sjukdomstillstånden kan också leda till svårigheter att klara av vardagen och bidra till försämrad livskvalitet. Det är av stor vikt att sjuksköterskan får en tydlig bild av vad som påverkar livskvaliteten hos patienten och till hjälp finns ett antal olika instrument för att mäta hälsa och livskvalitet, bl.a. The Schedule for the Evaluation of Individual Quality of Life - Direct Weighting (SEIQoL-DW). Syfte: Att undersöka individuell livskvalitet hos patienter med psykisk sjukdom med hjälp av SEIQoL-DW, samt att undersöka patienters och behandlares uppfattning om instrumentets tillämpbarhet och användbarhet. Metod: Patienter inom den psykiatriska vården fyllde i SEIQoL-DW-formuläret med stöd av behandlare. Därefter fyllde båda parterna i en enkät om instrumentets användbarhet. Materialet analyserades kvantitativt och kvalitativt. Resultat: Patienterna som deltog i studien skattade Relationer/Socialt nätverk som det viktigaste livsområdet, följt av Arbete. Det område som upplevdes fungera bäst, det vill säga det område som hade högst nivå, var Familj. Lägst nivå hade Arbete, vilket var det område som fungerade sämst. De flesta patienter och alla behandlare ansåg att frågorna i formuläret var relevanta respektive angelägna, samt att formuläret kan vara ett bra stöd vid samtalet. Runt hälften av patienterna ansåg att det helt eller delvis tog lång tid att fylla i formuläret. Slutsats: Trots att livskvalitet är något individuellt anger många patienter samma livsområden som viktiga. Instrumentet är användarvänligt till stor del, men patienten kan behöva stöd för att fylla i formuläret. / Background: People with mental illness have poorer health and increased mortality from somatic diseases compared with the general population. The diseases can also lead to difficulties in coping with everyday life and reduced quality of life. It is very important that the nurse gets a clear picture of what affects the patient’s quality of life. There are a number of different instruments for measuring health and quality of life, e.g. The Schedule for the Evaluation of Individual Quality of Life - Direct Weighting (SEIQoL-DW). Aim: To examine individual quality of life amongst patients with mental illness with the assistance of SEIQoL-DW. The second aim was to study the feasibility and applicability of the instrument. Method: Patients in psychiatric care filled in the SEIQoL-DW-form with support of the health care staff. Then both the patient and the health care staff filled in a questionnaire about the instrument's usability. The material was analyzed quantitatively and qualitatively. Results: Patients participating in the study estimated Relationships/Social network as the most important area of life. The area that generally was perceived to work best was Family, Work had the lowest level. Most of the patients and all of the health care staff considered the instrument to be relevant and a good support for the dialogue. About half of the patients considered the form to be time-consuming. Conclusion: Although quality of life is something individual, many of the patients stated the same areas of life as important. The instrument is user-friendly to a great extent, but the patient may need assistance to complete the form.

Social evolution in class-structured populationsRodrigues, Antonio M. M. January 2014 (has links)
Inclusive fitness theory concerns the study of social traits. Often, individuals differ in their phenotype (e.g. size, weight, nutritional state) independently of their genetic make up, that is, individuals differ in their quality. Individuals can then be classified into different “classes” according to their quality, which enable us to understand social evolution in class-structured populations. This is important because individuals in natural populations often differ in quality, either because of intrinsic factors (e.g. size), or extrinsic factors (e.g. resource availability). My thesis concerns the evolution of social traits in class-structured populations. In chapter 1, I make a brief introduction to my thesis, providing the abstract of each chapter. In chapter 2, I outline a general theory of individual quality, where I show how individual quality impacts social evolution in two fundamental ways. In chapter 3, I show that resource heterogeneity greatly influences the evolution of conditional social behaviour. In chapter 4, I show that temporal group-size heterogeneity promotes the evolution of both conditional helping and harming. In chapter 5, I analyse the effect of individual quality on kin selection. I find that individual quality has an important impact in kin selection, which can lead to extreme forms of social behaviour. In chapter 6, I show that stable environments promote the evolution of negative density-dependent dispersal, while unstable environments promote the evolution of positive density-dependent dispersal. In chapter 7, I show that budding and low local quality promote the evolution of dispersal and cooperation.

台灣血液透析患者的個人化生活品質:以SEIQoL-DW為測量工具 / Taiwan hemodialysis patients’ individual quality of life:assessed by SEIQoL-DW羅一哲, Luo, Yi Jhe Unknown Date (has links)
本研究目的為使用個人化生活品質評量表直接權重版(SEIQoL-DW),評估國內血液透析患者的個人化生活品質,探討對其特別重要的生活品質向度與相關影響因素,此外,並以Locke(1969, 1976)(引自Wu & Yao,2006b)的「情感間距假設」、Calman(1984)的期望理論與Wu(2009)提出的移轉傾向指標為基礎,探討SEIQoL-DW重要性評估程序的應用價值與潛在臨床應用指標。研究對象以立意取樣,自台北市松山區某私人洗腎中心募集57名血液透析患者、以及台北市文山區一般社區成人60名,研究工具包含SEIQoL-DW、生活滿意度量表、焦慮與憂鬱評量表、自編人口背景/疾病變項問卷,統計方法含描述性統計、卡方檢定、相關分析、平均數差異檢定與迴歸分析。研究結果發現,血液透析患者最常列舉的重要生活向度為健康(77%),其次依序為家庭(72%)、經濟(65%)、人際關係(53%)、休閒活動(49%)、因應/正向態度(23%)、工作/學業(21%)、心理健康(16%)、生活條件(16%)、靈性/信仰(9%)、角色功能(9%)、其他(9%),血液透析患者在各向度提名百分比與一般成人組未有顯著差異,但血液透析患者對健康向度的現況評比顯著較低,對健康的現況-期望落差也顯著較高,共病數與血液透析患者個人化生活品質指標有顯著負相關;而SEIQoL-DW項目重要性對項目現況分數與整體滿意度之間的關係不具調節效果,SEIQoL-DW的權重程序未能提升對整體滿意度的解釋力,此外,自項目重要性與現況-想望落差所得移轉傾向指標,和整體生活滿意度、SEIQoL-DW現況平均數亦未有一致的相關性或獨特解釋力。儘管本研究不支持SEIQoL-DW權重程序或衍生指標的助益,但若從個人脈絡來看,向度重要性仍可協助探索個案生活目標重要順序,有其臨床醫療應用價值;最後,SEIQoL-DW個人現況-想望落差分數、現況平均數、以及整體生活滿意度、負向情緒彼此有顯著關聯性與解釋力,在個案生活滿意度、負向情緒評估或介入方案中,具有成為臨床應用指標的潛力。 / The primary purpose of this thesis was using the Schedule for the Evaluation of Individual Quality of Life-Direct Weighting (SEIQoL-DW) to explore hemodialysis patients’ Individual Quality of Life and relative determinants. And further using affect-range hypothesis (Locke, 1969, 1976), expection theory (Calman,1984) and shifting tendency Index(Wu, 2009) as framework to evaluate SEIQoL-DW weighting procedure’s efficiency and potential clinical application variables. 57 hemodialysis patients and 60 counterparts was recruited from Taipei city, IQoL was assessed by SEIQoL-DW, the general life satisfaction and anxiety /depression statement was chosen as criterian variables. In the analysis, twelve quality of life domains were identified. Health(77%), family(72%), finance(65%), relations(53%) and leisure time(49%) were the most prominent quality of life domains of hemodialysis patients, although the domains nominated percentage and importance rating didn’t differ between groups, hemodialysis patients’ health domain status and have-want discrepancy were worse than the counterparts. Among the investgated variables, only the comorbidity had negative correlation with hemodialysis patients’ IQoL. The result didn’t support the SEIQoL-DW’s weighting procedure and shifting tendency Index had significant efficiency, but the weighing information could still be useful in personal profile context. Finally, the personal have-want discrepancy, satus average, general life satisfaction and anxiety/depression statement have significant relations with each other, thus could be the potential clinical application variables in negative emotion or life satisfaction intervention programs.

Variation in individual life-history trajectories and its consequence on population dynamics : the case of roe deerPlard, Floriane 06 March 2014 (has links) (PDF)
Roe deer give birth each year in May. At each reproductive event, a female can be in different reproductive statuses: breeder or non breeder and can wean a variable number of offspring. The successive transitions between the different statuses of a given female give its individual reproductive trajectory. The performance of a given trajectory is assessed by its fitness which can be approximated by the total number of offspring weaned during the trajectory. Different individual life-history trajectories can exist in a same population and these different trajectories can reach similar or different fitness. This suggests that different strategies can be chosen by different individuals to reach the same fitness but also that individuals of high quality can reach higher fitness than individuals of low quality. The study of a roe deer population located in North-Eastern France allowed analyzing the sources and the consequences of individual heterogeneity on individual life-history trajectories and on population dynamics. This work showed that roe deer individual reproductive trajectories are consistent for a given female such as high quality females have an annual reproductive success higher than low-quality females. Female quality is partly generated by birth condition such as birth date and environmental conditions at birth. Individual life-history trajectories vary also randomly in relation to annual environmental conditions. In particular, climate change led to a decline in annual mean reproductive success and a decrease of the population growth rate in the last decades in relation to an increase of the mismatch between vegetation phenology and roe deer birth period. This work discussed how individual heterogeneity is generated in a long-lived species and how it influences individual life-history strategies and population dynamics

Experiences of pain and associations between pain, disease severity and individual quality of life in people with motor neuron diseasesÅkerblom, Ylva January 2019 (has links)
Many people with the incurable and often times fatal motor neuron diseases have pain, but there is lack of knowledge about people’s experiences of living with pain. Further, the correlation between pain and their quality of life is not well understood, and previous studies have not used individual quality of life, namely that people with their own words express what quality of life is. The aim of these studies was to explore the experiences of pain and the association between pain and quality of life in people with MND. Methods: Study I was explorative about the individual experience of pain, while study II was correlational between pain, pain severity, disease severity and IQOL. Study I was qualitative, whereas study II used both qualitative and quantitative analysis. Results and conclusions: People with motor neuron diseases experienced pain to have multiple characteristics and impact. However, the results emphasise that the individual experienced some pain characteristics as difficult and that pain could worsen functions that were already affected by the disease. The experience was also that it could be challenging to manage pain. However, the symptom of pain could pass unnoticed in contacts with healthcare professionals (study I). The three most important areas for individual quality of life in both participants with and without pain were: Social relations, followed by Activities for amusement and relaxations, and Being in the outdoor environment. Individual quality of life was noticed to be good regardless of pain. Pain and pain severity were not found to be associated with satisfaction of individual quality of life in patients with motor neuron diseases, neither was disease severity. The results support previous findings, that strong associations between symptoms of MND and IQoL are not obvious. However, this does not infer that pain in people with MNDs should be neglected and undertreated. On the contrary, it seems to be important for healthcare to pay more attention to pain in people with motor neuron diseases and that pain continuously is measured, individually treated and followed. Regardless of whether persons with MND have pain or not, the results point to the importance of healthcare professionals providing support to not only the patient but also the patient’s family and friends, as well as assisting in various forms of relaxing activities and possibility of being in the outdoor environment.

Variation in individual life-history trajectories and its consequence on population dynamics : the case of roe deer / Variabilité des trajectoires de vie individuelles et ses conséquences sur la dynamique de population : le cas du chevreuilPlard, Floriane 06 March 2014 (has links)
Le chevreuil met bas chaque année en mai. À chaque évènement de reproduction, une femelle peut être dans différents états : reproducteur ou non reproducteur et elle peut élever un nombre variable de jeunes. La succession des transitions entre ces différents états constitue la trajectoire de reproduction d’un individu tout au long de sa vie. Chaque trajectoire est donc individuelle et la valeur de cette trajectoire une fois terminée est appréciée par sa valeur sélective qui peut être estimée comme le nombre de petits élevés au cours de la vie d’un individu. Différentes trajectoires individuelles peuvent exister au sein d’une même population et conduire à des valeurs sélectives similaires ou différentes montrant que différentes stratégies sont possibles pour atteindre la même valeur sélective mais aussi que certains individus de meilleure qualité peuvent atteindre une valeur sélective plus élevée que des individus de moins bonne qualité. L’étude d’une population de chevreuil située dans le Nord-Est de la France a permis d’étudier les sources et les conséquences de cette hétérogénéité individuelle sur les trajectoires d’histoire de vie individuelles et sur la dynamique de cette population. Ce travail de thèse a montré que chez le chevreuil, une trajectoire reproductive individuelle est en partie homogène et que les femelles de bonne qualité ont un succès annuel constant et plus marqué que les femelles de mauvaise qualité. La qualité de ces femelles est influencée par les conditions à la naissance comme la date de naissance et les conditions environnementales au cours de leur développement. Les trajectoires individuelles varient également aléatoirement en fonction des conditions environnementales annuelles. Ces dernières décennies, le changement climatique a donné naissance à un mismatch grandissant entre la période des mise-bas du chevreuil et la disponibilité en ressources qui a provoqué une diminution du succès reproducteur et de la croissance de la population. Ce travail a permis de discuter comment l’hétérogénéité individuelle est générée chez une espèce longévive et comment elle influence les stratégies démographiques et la dynamique de cette population / Roe deer give birth each year in May. At each reproductive event, a female can be in different reproductive statuses: breeder or non breeder and can wean a variable number of offspring.

Age, Longevity and Life-History Trade-Offs in the Collared Flycatcher (Ficedula albicollis)Sendecka, Joanna January 2007 (has links)
Age is often a neglected factor in ecological studies. However, age-related changes in reproduction and survival of organisms may strongly influence population dynamics. The Gotlandic population of collared flycatchers is a perfect system for studying age-related changes in the wild, as the exact age and reproductive history of most individuals is known. Collared flycatchers (Ficedula albicollis) on Gotland show the typical pattern of age-related changes in survival and reproductive success; both factors show an increase early in life and a decrease late in life. This thesis presents a broad study not only of age-related patterns of reproduction and immunity, but also proposes the mechanisms driving these patterns. My results show that in addition to survival probability and reproductive performance, reproductive costs and life-history trade-offs also change with progressing age. There is a significant increase in reproductive performance at the population level during first years of life which result from selection against low quality phenotypes. On the individual level this pattern is best explained by an optimization of reproductive effort. However, high quality individuals have higher reproductive success as early as their first breeding event and are long-lived. Thus, they seem to adopt a different strategy than lower quality, short-lived individuals. Differences in individual quality seem to be shaped by the developmental conditions experienced as nestlings. Fledglings with longer tarsi, but lower body mass become long-lived, high quality adults. Young individuals breeding for first time pay higher costs of reproduction. They also express a limited ability to reduce these costs by breeding in high quality territories when compared to middle-aged individuals. Young individuals seem to invest more into self-maintenance, whereas old individuals reduce the level of self-maintenance (measured as immune response) and redistribute their investment towards reproduction. Thus, old individuals are limited in their ability to reduce reproductive costs under favorable conditions, especially as they also senesce, which pattern is also shaped by individual quality. Variation in individual quality appears to have an strong effect on age-related survival probability, reproductive performance, reproductive costs, and even life-history decisions. Therefore, taking this factor into account in studies of life-history patterns is necessary to obtain reliable results.

Influence de la variabilité climatique, de l’abondance de proies, de la densité-dépendance et de l'hétérogénéité individuelle chez des prédateurs supérieurs longévifs : de l’individu à la population / Influences of climatic variability, prey abundance, density-dependence, and individual heterogeneity in long-lived top predators : from individual to populationPacoureau, Nathan 26 October 2018 (has links)
Une question fondamentale en écologie des populations est l’identification des facteurs influençant la dynamique d’une population. L’objectif principal de cette thèse est de déterminer quelles sont les réponses démographiques et populationnelles de prédateurs marins supérieurs face aux fluctuations d’abondance de leurs proies, aux variations climatiques, à la densité-dépendance tout en tenant compte de l’hétérogénéité inter et intra-individuelle (âge, expérience, sexe, qualité ou stratégie). Pour ce faire, nous nous baserons sur l’analyse de suivis à long-terme individuels et populationnels d’oiseaux marins longévifs et prédateurs apicaux phylogénétiquement très proches dans deux biomes contrastés : le labbe de McCormick Catharacta maccormicki sur l’archipel de Pointe Géologie en Antarctique et le labbe subantarctique Catharacta lonnbergi sur l’archipel des Kerguelen en milieu subantarctique. Nous tirerons parti d’estimations d’abondances de leurs proies respectives : le manchot Adélie Pygoscelis adeliae et le manchot empereur Aptenodytes forsteri en Antarctique, et le pétrel bleu Halobaena caerulea et le prion de Belcher Pachyptila belcheri à Kerguelen. Ces jeux de données offrent une opportunité unique de pouvoir déterminer et quantifier simultanément les différentes sources de variabilité dans les changements de taille de populations naturelles occupant l’un des niveaux trophiques les plus élevés des réseaux alimentaires antarctiques et subantarctiques. Nous avons mis en évidence de la variation dans plusieurs traits vitaux des deux populations influencées par les performances des individus et de l’hétérogénéité individuelle latente. Nous discutons des mécanismes par lesquels la variabilité climatique, l’abondance de proie et la densité de population peuvent affecter différentiellement les différentes classes d’âges de chaque trait vital, et les conséquences potentielles de futurs changements environnementaux. / A fundamental endeavor in population ecology is to identify the drivers of population dynamics. The main objective of this thesis is to determine what are the demographic and population responses of superior marine predators to the fluctuations of their prey abundance, to climatic variations, to density-dependence while taking into account inter and intra individual heterogeneity (age, experience, sex, quality or strategy). To do this, we analysed long-term individual and population-based monitoring of long-lived seabirds and phylogenetically close apical predators in two contrasting biomes: the south polar skua Catharacta maccormicki at Pointe Géologie archipelago, Antarctica, and the brown skua Catharacta lonnbergi on the sub-Antarctic Kerguelen Archipelago. We will use direct abundance of their respective prey: Adélie penguin Pygoscelis adeliae and emperor penguin Aptenodytes forsteri in Antarctica, and the blue petrel Halobaena caerulea and the thin-billed prion Pachyptila belcheri prion in Kerguelen islands. These datasets provide a unique opportunity to simultaneously disentangle and quantify the different sources of variability driving variation in natural populations occupying one of the highest trophic levels of the Antarctic and sub-Antarctic food webs. We found variation in several vital traits of both populations influenced by individual performance and latent individual heterogeneity. We discuss the mechanisms by which climatic variability, prey abundance, and population density can differentially affect the different age classes of each age class, and the potential consequences of future environmental changes.

De l’envol à la première reproduction : aspects écologiques et évolutifs des traits d’histoire de vie de jeunes oiseaux marins longévifs / From fledgling to the first reproduction : ecological and evolutionary aspect of life-history traits of young long-lived seabirdFay, Rémi 21 February 2017 (has links)
Jusqu’à aujourd’hui, les traits démographiques du début de vie ont été peu étudiés relativement aux traits adultes chez une grande majorité d’espèces animales. Les jeunes individus sont généralement plus difficiles à étudier en milieu naturel du fait de leur taille plus petite, de leur comportement plus mobile et des forts taux de mortalité qu’ils subissent. Cependant, la bonne compréhension des processus démographiques requiert la prise en compte de l’ensemble des stades de vie. Le manque de connaissance concernant les plus jeunes individus est particulièrement préjudiciable pour les espèces longévives. En effet chez ces espèces, les individus immatures représentent une partie importante de la valeur reproductive totale et ont ainsi une forte influence sur l’ensemble de la dynamique de la population. Ainsi, ces lacunes affectent notre capacité à effectuer des projections démographiques réalistes dans un contexte de changements globaux et plus généralement limitent notre compréhension de l’évolution des traits d’histoire de vie. Afin de pallier à ce manque, cette thèse porte sur l’étude des traits d’histoire de vie en début de vie chez une espèce d’oiseau marin : l’albatros hurleur Diomedea exulans. Chez cette espèce particulièrement longévive, la période d’immaturité peut durer une dizaine d’années. En se basant sur un suivi individuel à long terme et des analyses de type capture-marquage-recapture, nous avons estimé la survie en début de vie ainsi que l’accès à la première reproduction en fonction de l’âge et du sexe. Nous avons également étudié les effets potentiels de facteurs extrinsèques (climat, pêcherie) et intrinsèques (densité dépendance, âge parental) sur ces paramètres. De nombreuses relations entre les taux vitaux de ces jeunes individus et leur environnement ont été décrites. Sur un plan plus théorique, nous avons également pu tester différentes prédictions comme la canalisation des traits d’histoire de vie ou l’existence de différentes stratégies d’histoire de vie au sein d’une même population. Au cours de ce travail, une attention particulière a été portée aux variations des traits démographiques à l’échelle individuelle. Notre étude montre que les taux vitaux d’individus de même âge et de même sexe peuvent être très variables. Nous avons pu associer les traits démographiques en début de vie aux performances futures au stade adulte et révéler certaines causes de ces variations interindividuelles. / To date, early life demographic traits have been poorly studied compare to adult traits in the vast majority of animal species. Young individuals are usually more difficult to study due to their small size, their mobile behavior and the high mortality rate that characterizes their life stage. However, the full understanding of the demographic processes requires the integration of all life stages. This lack of knowledge toward early-life stages is particularly detrimental for long lived species. Indeed for these species, the immature component represents a substantial part of the total reproductive value, having a high influence on the whole population dynamics. Hence, such limitations affect the accuracy of population projections in the context of global change and more generally our understanding of life history trait evolution. In order to fill in this gap, this PhD project focuses on early life demographic traits in a seabird species : the wandering albatross Diomedea exulans. In this very long-lived species, the immature period lasts around 10 years. Based on long-term individual monitoring and capture-recapture analyses, we estimated early-life survival and the access to reproduction according to age and sex. We also investigates the respective effects of extrinsic (e.g. climate, fisheries) and intrinsic factors (e.g. density dependence, parental effects) on these parameters. Many relationships between early-life vital rates and environmental variables have been described. From a theoretical perspective, we tested several predictions such as the canalization of life-history traits and the existence of different life-history strategies within a population. In this work, special attention was paid to demographic variations at the individual scale. Our study showed that vital rates of individuals of the same age and sex could be very different. We have linked early-life demographic traits with subsequent adult performances and identified some causes of these individual variations.

Kondiční závislost pohlavně selektovaných ornamentů u ptáků / Condition dependence of sexually selected ornaments in birdsTomášek, Oldřich January 2018 (has links)
Sexual ornaments important for mating success in many species are often assumed to evolve as condition-dependent signals of individual quality. Ornament expression can be associated with age and survival, thereby signalling individual viability. Here, we have tested viability signalling function of tail streamers and their importance for within-pair and extra-pair fertilisation success in the European barn swallow (Hirundo rustica rustica). In contrast to previous studies on this subspecies, our data suggest that tail length is not associated with fertilisation success in our population. Instead, the most important predictors of within-pair and extra-pair fertilisation success were female and male age, respectively. Our data supported viability signalling function of male tail streamers, as documented by age-related within- individual increase in their length. There was no evidence for senescence in this trait. Contrary to some previous studies, the viability signalling function of tail streamers was further supported by observed selective disappearance of males with shorter tails. Several physiological mechanisms have been proposed as maintaining signalling honesty. Among them, oxidative stress from highly reactive species (RS), including free radicals, attracted a considerable attention. Given...
