Kampen om Eros : Om kön och kärlek i Pahlensviten

The Struggle for Eros: On Love and Gender in the Pahlen Series The present dissertation examines how gender, sexuality and motherhood are constructed in the novel series Fröknarna von Pahlen (The Misses von Pahlen, I VII, 1930 1935) by the Swedish author Agnes von Krusenstjerna. The aim of the study is to analyze how the Pahlen series relates to the discourses on gender and sexuality circulating in the 1930s, and how the series opens a dialogue with the feminist thinking of the time especially with the book Lifslinjer I (Love and Marriage, 1903) by the Swedish author Ellen Key. Fröknarna von Pahlen holds a central position in the research on Agnes von Krusenstjerna partly due to the literary debate that the novel series triggered. The debate was connected to the development taking place in the Swedish society in the beginning of the 1930s, in the so-called second phase of the Modern Breakthrough. Sweden was at that time characterized by struggle over the definitions of gender, sexuality and parenthood, and this struggle is also visible in the Pahlen series. The literary debate took place in 1934 1935 and it began after an article by the modernist writer Karin Boye was published in Social-Demokraten on 28 January 1934. In her polemic article, Boye saw the Pahlen series as a sign that the family institution is on the verge of a breakdown and with it the whole moral system that has come to existence through it . Boye went on to state that Krusenstjerna only sees and describes and that she explores neither new literary forms nor new values. Boye wrote the article before the last two parts of the novel series were published, so obviously she could not discuss the utopian vision characterizing those parts. This study, however, strives to demonstrate that Krusenstjerna not only sees and describes, but that she like many of her contemporary female colleagues appears to take the request of Friedrich Nietzsche to revaluate all values seriously. Like the works of her contemporaries, Krusenstjerna s Pahlen series is marked by a double vision on the one hand a critique of the prevailing social order, and on the other hand a dream of a new world and a new human being. In this research the vision of the Pahlen series is characterized as queer in order to emphasize that the series not only criticizes the prevailing gender order and its morals, but is also open for new ways of doing gender, parenthood, and family.

Rab8 and Rab8-interacting proteins as players in cell polarization

Rab8 and its interacting proteins as regulators of cell polarization During the development of a multi-cellular organism, progenitor cells have to divide and migrate appropriately as well as organize their differentiation with one another, in order to produce a viable embryo. To divide, differentiate and migrate cells have to undergo polarization, a process where internal and external components such as actin, microtubules and adhesion receptors are reorganized to produce a cell that is asymmetric, with functionally different surfaces. Also in the adult organism there is a continuous need for these processes, as cells need to migrate in response to tissue damage and to fight infection. Improper regulation of cell proliferation and migration can conversely lead to disease such as cancer. GTP-binding proteins function as molecular switches by cycling between a GTP-bound (active) conformation and a GDP-bound (inactive) conformation. The Ras super-family of small GTPases are found in all eukaryotic cells. They can be functionally divided into five subfamilies. The Ras family members mainly regulate gene expression, controlling cell proliferation and differentiation. Ras was in fact the first human oncogene to be characterized, and as much as 30% of all human tumors may be directly or indirectly caused by mutations of Ras molecules The Rho family members mainly regulate cytoskeletal reorganization. Arf proteins are known to regulate vesicle budding and Rab proteins regulate vesicular transport. Ran regulates nuclear transport as well as microtubule organization during mitosis. The focus of the thesis of Katarina Hattula, is on Rab8, a small GTPase of the Rab family. Activated Rab8 has previously been shown to induce the formation of new surface extensions, reorganizing both actin and microtubules, and to have a role in directed membrane transport to cell surfaces. However, the exact membrane route it regulates has remained elusive. In the thesis three novel interactors of Rab8 are presented. Rabin8 is a Rab8-specific GEF that localizes to vesicles where it presumably recruits and activates its target Rab8. Its expression in cells leads to remodelling of actin and the formation of polarized cell surface domains. Optineurin, known to be associated with a leading cause of blindness in humans (open-angle glaucoma), is shown to interact specifically with GTP-bound Rab8. Rab8 binds to an amino-terminal region and interestingly, the Huntingtin protein binds a carboxy-terminal region of optineurin. (Aberrant Huntingtin protein is known to be the cause Huntington s disease in humans.) Co-expression of Huntingtin and optineurin enhanced the recruitment of Huntingtin to Rab8-positive vesicular structures. Furthermore, optineurin promoted cell polarization in a similar way to Rab8. A third novel interactor of Rab8 presented in this thesis is JFC1, a member of the synaptogamin-like protein (Slp) family. JFC1 interacts with Rab8 specifically in its GTP-bound form, co-localizes with endogenous Rab8 on tubular and vesicular structures, and is probably involved in controlling Rab8 membrane dynamics. Rab8 is in this thesis work clearly shown to have a strong effect on cell shape. Blocking Rab8 activity by expression of Rab8 RNAi, or by expressing the dominant negative Rab8 (T22N) mutant leads to loss of cell polarity. Conversely, cells expressing the constitutively active Rab8 (Q67L) mutant exhibit a strongly polarized phenotype. Experiments in live cells show that Rab8 is associated with macropinosomes generated at ruffling areas of the membrane. These macropinosomes fuse with or transform into tubules that move toward the cell centre, from where they are recycled back to the leading edge to participate in protrusion formation. The biogenesis of these tubules is shown to be dependent on both actin and microtubule dynamics. The Rab8-specific membrane route studied contained several markers known to be internalized and recycled (1 integrin, transferrin, transferrin receptor, cholera toxin B subunit (CTxB), and major histocompatibility complex class I protein (MHCI)). Co-expression studies revealed that Rab8 localization overlaps with that of Rab11 and Arf6. Rab8 is furthermore clearly functionally linked to Arf6. The data presented in this thesis strongly suggests a role for Rab8 as a regulator for a recycling compartment, which is involved in providing structural and regulatory components to the leading edge to participate in protrusion formation.

Molecular pathogenesis of human parechovirus 1 infection

The Parechoviruses (HPEV) belong to the family Picornaviridae of positive-stranded RNA viruses. Although the parechovirus genome shares the general properties of other picornaviruses, the genus has several unique features when compared to other family members. We found that HPEV1 attaches to αv integrins on the cell surface and is internalized through the clathrin-mediated endocytic pathway. During he course of the infection, the Golgi was found to disintegrate and the ER membranes to swell and loose their ribosomes. The replication of HPEV1 was found to take place on small clusters of vesicles which contained the trans-Golgi marker GalT as well as the viral non-structural 2C protein. 2C was additionally found on stretches of modified ER-membranes, seemingly not involved in RNA replication. The viral non-structural 2A and 2C proteins were studied in further detail and were found to display several interesting features. The 2A protein was found to be a RNA-binding protein that preferably binds to positive sense 3 UTR RNA. It was found to bind also duplex RNA containing 3 UTR(+)-3 UTR(-), but not other dsRNA molecules studied. Mutagenesis revealed that the N-terminal basic-rich region as well as the C-terminus, are important for RNA-binding. The 2C protein on the other hand, was found to have both ATP-diphosphohydrolase and AMP kinase activities. Neither dATP nor other NTP:s were suitable substrates. Furthermore, we found that as a result of theses activities the protein is autophosphorylated. The intracellular changes brought about by the individual HPEV1 non-structural proteins were studied through the expression of fusion proteins. None of the proteins expressed were able to induce membrane changes similar to those seen during HPEV1 infection. However, the 2C protein, which could be found on the surface of lipid droplets but also on diverse intracellular membranes, was partly relocated to viral replication complexes in transfected, superinfected cells. Although Golgi to ER traffic was arrested in HPEV1-infected cells, none of the individually expressed non-structural proteins had any visible effect on the anterograde membrane traffic. Our results suggest that the HPEV1 replication strategy is different from that of many other picornaviruses. Furthermore, this study shows how relatively small differences in genome sequence result in very different intracellular pathology.

Molecular biology and functions of epilysin (MMP-28)

Epilysin (MMP-28) is the most recently identified member of the matrix metalloproteinase (MMP) family of extracellular proteases. Together these enzymes are capable of degrading almost all components of the extracellular matrix (ECM) and are thus involved in important biological processes such as development, wound healing and immune functions, but also in pathological processes such as tumor invasion, metastasis and arthritis. MMPs do not act solely by degrading the ECM. They also regulate cell behavior by releasing growth factors and biologically active peptides from the ECM, by modulating cell surface receptors and adhesion molecules and by regulating the activity of many important mediators in inflammatory pathways. The aim of this study was to define the unique role of epilysin within the MMP-family, to elucidate how and when it is expressed and how its catalytic activity is regulated. To gain information on its essential functions and substrates, the specific aim was to characterize how epilysin affects the phenotype of epithelial cells, where it is biologically expressed. During the course of the study we found that the epilysin promoter contains a well conserved GT-box that is essential for the basic expression of this gene. Transcription factors Sp1 and Sp3 bind this sequence and could hence regulate both the basic and cell type and differentiation stage specific expression of epilysin. We cloned mouse epilysin cDNA and found that epilysin is well conserved between human and mouse genomes and that epilysin is glycosylated and activated by furin. Similarly to in human tissues, epilysin is normally expressed in a number of mouse tissues. The expression pattern differs from most other MMPs, which are expressed only in response to injury or inflammation and in pathological processes like cancer. These findings implicate that epilysin could be involved in tissue homeostasis, perhaps fine-tuning the phenotype of epithelial cells according to signals from the ECM. In view of these results, it was unexpected to find that epilysin can induce a stable epithelial to mesenchymal transition (EMT) when overexpressed in epithelial lung carcinoma cells. Transforming growth factor b (TGF-b) was recognized as a crucial mediator of this process, which was characterized by the loss of E-cadherin mediated cell-cell adhesion, elevated expression of gelatinase B and MT1-MMP and increased cell migration and invasion into collagen I gels. We also observed that epilysin is bound to the surface of epithelial cells and that this interaction is lost upon cell transformation and is susceptible to degradation by membrane type-1-MMP (MT1-MMP). The wide expression of epilysin under physiological conditions implicates that its effects on epithelial cell phenotype in vivo are not as dramatic as seen in our in vitro cell system. Nevertheless, current results indicate a possible interaction between epilysin and TGF-b also under physiological circumstances, where epilysin activity may not induce EMT but, instead, trigger less permanent changes in TGF-b signaling and cell motility. Epilysin may thus play an important role in TGF-b regulated events such as wound healing and inflammation, processes where involvement of epilysin has been indicated.

Individuals on the Move : Body Condition Dependent Dispersal and Quasi-Local Competition in Metapopulations

Individual movement is very versatile and inevitable in ecology. In this thesis, I investigate two kinds of movement body condition dependent dispersal and small-range foraging movements resulting in quasi-local competition and their causes and consequences on the individual, population and metapopulation level. Body condition dependent dispersal is a widely evident but barely understood phenomenon. In nature, diverse relationships between body condition and dispersal are observed. I develop the first models that study the evolution of dispersal strategies that depend on individual body condition. In a patchy environment where patches differ in environmental conditions, individuals born in rich (e.g. nutritious) patches are on average stronger than their conspecifics that are born in poorer patches. Body condition (strength) determines competitive ability such that stronger individuals win competition with higher probability than weak individuals. Individuals compete for patches such that kin competition selects for dispersal. I determine the evolutionarily stable strategy (ESS) for different ecological scenarios. My models offer explanations for both dispersal of strong individuals and dispersal of weak individuals. Moreover, I find that within-family dispersal behaviour is not always reflected on the population level. This supports the fact that no consistent pattern is detected in data on body condition dependent dispersal. It also encourages the refining of empirical investigations. Quasi-local competition defines interactions between adjacent populations where one population negatively affects the growth of the other population. I model a metapopulation in a homogeneous environment where adults of different subpopulations compete for resources by spending part of their foraging time in the neighbouring patches, while their juveniles only feed on the resource in their natal patch. I show that spatial patterns (different population densities in the patches) are stable only if one age class depletes the resource very much but mainly the other age group depends on it.

Stor Anna, Liten Anna och tio andra personporträtt : Om innehållsliga och språkliga mönster i en mediegenres kvinnobeskrivningar

The aim of this licentiate thesis is to analyse how femininity is constructed in twelve portrait interviews of women in the dailies Dagens Nyheter (Stockholm) and Hufvudstadsbladet (Helsinki) in September 1996, and to explore the portrait interview as a media genre. The qualitative analysis has a feminist and constructionist perspective and is connected to critical text analysis. It was carried out on two levels: first, femininity is identified on the linguistic level by choice of words, and second on the level of content (topical motifs/themes). The portrait interview as a genre constitutes a third dimension in the analysis: The aim is not towards the identification of femininity, but rather towards the identification of the portrait interview a relatively unexplored media genre. References (Swedish: omtal) to the principal character (or protagonist) are traced mainly through reference chains which consist of names, pronouns and substantive phrases. The interviewees were referred to by their full names in Dagens Nyheter (with the exception of the oldest and youngest interviewees, both of whom were mainly referred to by their first names), while the style of reference varied more in Hufvudstadsbladet. The position of the principal character was also analysed through her relation in the text to minor characters from her working life and from her private life. These minor characters maintained their subordinate positions in all of the portraits except that of the youngest principal character, in which the subsidiary voices became at least as strong as the voice of the principal character. Three frequently-recurring topical motifs occurred in the portraits: The first involved explanations for the principal character s success divided into three categories, agent, affect and ambition, the second concerned using journeys or trips as symbols for turning points in life, and the third referred to the ambiguity in the contradiction between private (family/other private life) and public (work) life. This ambiguity is connected to the portrait interview as a text type (genre) which features conclusions at the end of portraits, which in turn is characteristic of reportage. However, the analysis showed that the conclusions of the portrait interviews often also included elements of ambiguity. This was evident in the contradictions be14 tween private and public life that arose in the portrait interviews that focused on these two spheres. The portraits that focused on the principal character s public life showed ambiguity on a more general level concerning questions about being a woman and having a profession, and they often ended with a description of some details of her private life. The women in the portraits were all constructed as being successful, in terms of having achieved direct success, reflective success or success in the form of life wisdom. The women of direct success were described as ambitious individuals with no sidetracks on their life paths, while those of reflective success were described as active heroines who had received help from different agents, who could use their affects as enriching ingredients in life, but who in the end had control over their own lives (life stories). The elderly women were constructed as having achieved life wisdom and their portraits were focused upon the past. The portrait interview as a genre is characterised by journalistic freedom (in relation to the more strict news genre), by a now room (Swedish nurum ) where the journalist meets the principal character (usually via spoken dialogue that she or he transforms into written text to be read by a mass-media audience) and by the relatively closed structure of the portrait. The portrait is relatively independent in relation to the news genre and in relation to the context of what has previously been written, what is being written at the time and what will be written in the future the principal character does not need to belong to the newspaper s usual gallery of actors. Furthermore, the principal character is constructed as being independent in relation to the subsidiary characters and other media actors. The conflict is within the principal character herself and within her life story, unlike the news genre in which equal actors are in conflict with each other. The portrait is also independent in relation to the news lifespan; the publishing timetable is not as strict as in the news genre, but is still dependent on the factors initiating the portrait. The enclosures consist of a raw analysis of two of twelve portrait interviews and of copies of all portraits.

MECHANISMS AND EFFECTS OF MITOCHONDRIAL DNA INSTABILITY AND COPY NUMBER MANIPULATION

Defects in mitochondrial DNA (mtDNA) maintenance cause a range of human diseases, including autosomal dominant progressive external ophthalmoplegia (adPEO). This study aimed to clarify the molecular background of adPEO. We discovered that deoxynucleoside triphosphate (dNTP) metabolism plays a crucial in mtDNA maintenance and were thus prompted to search for therapeutic strategies based on the modulation of cellular dNTP pools or mtDNA copy number. Human mtDNA is a 16.6 kb circular molecule present in hundreds to thousands of copies per cell. mtDNA is compacted into nucleoprotein clusters called nucleoids. mtDNA maintenance diseases result from defects in nuclear encoded proteins that maintain the mtDNA. These syndromes typically afflict highly differentiated, post-mitotic tissues such as muscle and nerve, but virtually any organ can be affected. adPEO is a disease where mtDNA molecules with large-scale deletions accumulate in patients tissues, particularly in skeletal muscle. Mutations in five nuclear genes, encoding the proteins ANT1, Twinkle, POLG, POLG2 and OPA1, have previously been shown to cause adPEO. Here, we studied a large North American pedigree with adPEO, and identified a novel heterozygous mutation in the gene RRM2B, which encodes the p53R2 subunit of the enzyme ribonucleotide reductase (RNR). RNR is the rate-limiting enzyme in dNTP biosynthesis, and is required both for nuclear and mitochondrial DNA replication. The mutation results in the expression of a truncated form of p53R2, which is likely to compete with the wild-type allele. A change in enzyme function leads to defective mtDNA replication due to altered dNTP pools. Therefore, RRM2B is a novel adPEO disease gene. The importance of adequate dNTP pools and RNR function for mtDNA maintenance has been established in many organisms. In yeast, induction of RNR has previously been shown to increase mtDNA copy number, and to rescue the phenotype caused by mutations in the yeast mtDNA polymerase. To further study the role of RNR in mammalian mtDNA maintenance, we used mice that broadly overexpress the RNR subunits Rrm1, Rrm2 or p53R2. Active RNR is a heterotetramer consisting of two large subunits (Rrm1) and two small subunits (either Rrm2 or p53R2). We also created bitransgenic mice that overexpress Rrm1 together with either Rrm2 or p53R2. In contrast to the previous findings in yeast, bitransgenic RNR overexpression led to mtDNA depletion in mouse skeletal muscle, without mtDNA deletions or point mutations. The mtDNA depletion was associated with imbalanced dNTP pools. Furthermore, the mRNA expression levels of Rrm1 and p53R2 were found to correlate with mtDNA copy number in two independent mouse models, suggesting nuclear-mitochondrial cross talk with regard to mtDNA copy number. We conclude that tight regulation of RNR is needed to prevent harmful alterations in the dNTP pool balance, which can lead to disordered mtDNA maintenance. Increasing the copy number of wild-type mtDNA has been suggested as a strategy for treating PEO and other mitochondrial diseases. Only two proteins are known to cause a robust increase in mtDNA copy number when overexpressed in mice; the mitochondrial transcription factor A (TFAM), and the mitochondrial replicative helicase Twinkle. We studied the mechanisms by which Twinkle and TFAM elevate mtDNA levels, and showed that Twinkle specifically implements mtDNA synthesis. Furthermore, both Twinkle and TFAM were found to increase mtDNA content per nucleoid. Increased mtDNA content in mouse tissues correlated with an age-related accumulation of mtDNA deletions, depletion of mitochondrial transcripts, and progressive respiratory dysfunction. Simultaneous overexpression of Twinkle and TFAM led to a further increase in the mtDNA content of nucleoids, and aggravated the respiratory deficiency. These results suggested that high mtDNA levels have detrimental long-term effects in mice. These data have to be considered when developing and evaluating treatment strategies for elevating mtDNA copy number.

Embedded Storytelling and Gender Negotiations in Githa Hariharan's First Three Novels

This thesis treats Githa Hariharan s first three novels The Thousand Faces of Night (1992), The Ghosts of Vasu Master (1994) and When Dreams Travel (1999) as a trilogy, in which Hariharan studies the effects of storytelling from different perspectives. The thesis examines the relationship between embedded storytelling and the primary narrative level, the impact of character-bound storytelling on personal development and interpersonal relationships. Thus, I assume that an analysis of the instabilities between characters, and tensions between sets of values introduced through storytelling displays the development of the central characters in the novels. My focus is on the tensions between different sets of values and knowledge systems and their impact on the gender negotiations. The tensions are articulated through a resistance and/or adherence to a cultural narrative, that is, a formula, which underlies specific narratives. Conveyed or disputed by embedded storytelling, the cultural narrative circumscribes what it means to be gendered in Hariharan s novels. The analysis centres on how the narratee in The Thousand Faces of Night and the storyteller in The Ghosts of Vasu Master relate to and are affected by the storytelling, and how they perceive their gendered positions. The analysis of the third novel When Dreams Travel focuses on storytelling, and its relationship to power and representation. I argue that Hariharan's use of embedded storytelling is a way to renegotiate and even reconceptualise gender. Hariharan s primary concern in all three novels is the tensions between tradition or repetition, and change, and how they affect gender. Although the novels feature ancient mythical heroes, mice and flies, or are set in a fantasy world of jinnis and ghouls, they are, I argue, deeply concerned with contemporary issues. Whereas the first novel questions the demands set by family and society on the individual, the second strives to articulate an ethical relationship between the self and the other. The third novel examines the relationship between representation and power. These issues could not be more contemporary, and they loom large over both the regional and global arenas.

Molecular diagnosis of developmental disorders

ABSTRACT Idiopathic developmental disorders (DDs) affect ~1% of the population worldwide. This being a considerable amount, efforts are being made to elucidate the disease mechanisms. One or several genetic factors cause 30-40% of DDs, and only 10% are caused by environmental factors. The remaining 50% of DD patients go undiagnosed, mostly due to a lack of diagnostic techniques. The cause in most undiagnosed cases is though to be a genetic factor or a combination of genetic and environmental factors. Despite the surge of new technologies entering the market, their implementation into diagnostic laboratories is hampered by costs, lack of information about the expected diagnostic yield, and the wide range of selection. This study evaluates new microarray methods in diagnosing idiopathic DDs, providing information about their added diagnostic value. Study I analysed 150 patients by array comparative genomic hybridization (array CGH, 44K and 244K), with a subsequent 18% diagnostic yield. These results are supported by other studies, indicating an enourmous added diagnostic value of array CGH, compared with conventional cytogenetic analysis. Nevertheless, 80% of the patients remained undiagnosed in Study I. In an effort to diagnose more patients, in Study IV the resolution was increased from 8.9 Kb of the 244K CGH array to 0.7 Kb, by using a single-nucleotide polymorphism (SNP) array. However, no additional pathogenic changes were detected in the 35 patients assessed, and thus, for diagnostic purposes, an array platform with ca 9 Kb resolution appears adequate. The recent vast increase in reports of detected aberrations and associated phenotypes has enabled characterization of several new syndromes first based on a common aberration and thereafter by delineation of common clinical characteristics. In Study II, a familial deletion at 9q22.2q22.32 with variable penetrance was described. Despite several reports of aberrations in the adjacent area at 9q associated with Gorlin syndrome, the patients in this family had a unique phenotype and did not present with the syndrome. In Study III, a familial duplication of chromosome 6p22.2 was described. The duplication caused increased expression of an important enzyme of the γ-aminobutyric acid (GABA) degradation pathway, causing oxidative stress of the brain, and thus, very likely, the mild mental retardation of these patients. These two case studies attempted to pinpoint candidate genes and to resolve the pathogenic mechanism causing the clinical characteristics of the patients. Presenting rare genetic and clinical findings to the international science and medical community enables interpretation of similar findings in other patients. The added value of molecular karyotyping in patients with idiopathic DD is evident. As a first line of testing, arrays with a median resolution of at least 9 Kb should be considered and further characterization of detected aberrations undertaken when possible. Diagnostic whole-exome sequencing may be the best option for patients who remain undiagnosed after high-resolution array analysis.

"Tekniken fångar mig" : Hur högstadie- och gymnasieflickor tänker om biologi, kemi, fysik och teknik

Den här studien tar sin utgångspunkt i genusteorier och de naturvetenskapliga och tekniska ämnesområdena i skolsammanhang. Syftet är att undersöka vad flickor tänker om ämnena biologi, kemi, fysik och teknik och hur det påverkar valet av fortsatta studier. I undersökningen deltar flickor i grundskolans årskurs 9 och gymnasiets årskurs 3. I undersökningen användes intervjuer, fokussamtal och enkäter. Resultaten visar att ett personligt ämnesintresse, den egna förmågan och förebilder i familj och kamrater bidrar till att flickor väljer naturvetenskapliga och tekniska studier. Betydelsefullt är att ämnesintresset på något sätt finns i flickornas vardagsliv exempelvis ett naturintresse. Av vikt för att flickorna väljer dessa studier är att de befinner sig i en omgivning, ex familj, som stödjer och främjar naturvetenskapliga och tekniska intressen och studier. Resultaten visar också några av de egenskaper som behövs för att göra gränsöverskridande studieval. Däremot visar resultatet att arbetssätten påverkar i mindre grad till ett personligt intresse för fortsatta studier. Identifieringen med en grupp för att känna tillhörighet är av betydelse i val av ämnesstudier.

Bröstcancer : Kvinnors upplevelser och behov av stöd efter radikal mastektomi

Syftet med denna systematiska litteraturstudie var att beskriva de bröstcancerdrabbade kvinnornas upplevelser efter radikal mastektomi och deras behov av stöd efter operationen. Studien baserades på 20 vetenskapliga artiklar med både kvalitativ och kvantitativ ansats. Urvalet av artiklar genomfördes genom att använda Högskolan Dalarnas databaser där olika sökord kombinerades. Även manuell sökning genomfördes. Granskningen av artiklarna utfördes med hjälp av en modifierad granskningsmall. Resultatet visade att en mängd olika reaktioner uppstod efter operationen. Kvinnorna upplevde en negativ bild av sig själva vilket medförde att de inte accepterade sin nya kropp och identitet. Det var även vanligt att de bröstcanceropererade isolerade sig från omgivningen och skylde sin bröstförlust inför andra. Kvinnors bröst var ofta förknippat med sexualitet och när de miste sitt bröst efter mastektomin påverkade det även relationen till partnern. Efter operationen var de bröstcancerdrabbade i stort behov av stöd. Det sociala och emotionella stödet innebar för kvinnorna att de hade någon som lyssnade och stöttade dem. Genom att erbjuda dem informativt stöd upplevde de en större trygghet inför framtiden. Även det praktiska stödet var betydelsefullt för kvinnorna då de fick hjälp av familj och vänner med olika göromål.

Prostatacancer - Männens Upplevelser av Livskvalitet samt Behov av Stöd från Sjuksköterskan och Närstående : Systematisk Litteraturstudie

Syftet med denna systematiska litteraturstudie var att beskriva männens upplevelser av livskvalitet vid prostatacancer samt deras behov av stöd från sjuksköterskan och närstående. Studiens resultat grundade sig på 17 vetenskapliga artiklar av både kvalitativ samt kvantitativ ansats. Artiklarna söktes med hjälp av valda sökord via Högskolan Dalarnas databaser. Artiklarna kvalitetgranskades utifrån modifierade granskningsmallar. Resultatet visade att män med prostatacancer upplevde urininkontinens som den svåraste emotionella upplevelsen och de kände stor frustration över att inte kunna kontrollera sin vattenkastning. Männen negligerade sina kroppar på grund av sina inkontinensbesvär. Männen beskrev även att de upplevde en saknad efter lust för sexuell samvaro speciellt de yngre männen som uttryckte förtvivlan över sin nedsatta erektionsförmåga. Männen upplevde förändringarna i sin identitet och maskulinitet som mycket smärtsamma. I stödet från sjuksköterskan beskrev männen att de kände en saknad efter att få diskutera existentiella frågor och tankar med sjuksköterskan medan andra män upplevde att sjuksköterskan bemötte deras behov av stöd. Männen kände sig lugna när de samtalat med sjuksköterskan. I stödet från närstående uppskattade männen sin partners omtanke och förståelse. De förlitade sig främst på sin partner och familj som fanns vid deras sida för att tillsammans dela de djupaste tankar och funderingar.

Familjens upplevelser vid palliativ vård av ett barn i familjen. : Sjuksköterskans betydelse i mötet med familjen.

Denna litteraturstudies syfte var att beskriva familjens och det sjuka barnets upplevelse av palliativ vård. Studien syftade dessutom till att beskriva vad familjen ansåg var mest betydelsefullt i mötet med sjuksköterskan i den palliativa vården. Inför uppsatsskrivandet har vetenskapliga artiklar i följande databaser sökts: Blackwell synergy, Ebsco Host Elin@dalarna, Pubmed. Sökorden användes i olika kombinationer. De vetenskapliga artiklarna har granskats med hjälp av granskningsmallar. Inklusionskriterierna för studien var att endast använda vetenskapliga artiklar i fulltext skrivna på engelska eller ett nordiskt språk samt vara av medel eller hög kvalitet. Artiklarna skulle vara publicerade mellan åren 1998-2008 samt bestå av primärkällor. Resultatet som framkom ur studien visade att familjen uppskattade då en relation kunde byggas upp mellan sjuksköterska och familj. Både det yngre och det äldre barnet uppskattade relationen med sjuksköterskan då det fick dem att känna sig speciella. En fördel var om det sjuka barnet hade en och samma vårdgivare under sjukdomstiden eftersom detta lättare bidrog till goda relationer samt att det skapade en trygghet för familjen och barnet. Möjligheter att aktivt delta i det sjuka barnets vård önskade många föräldrar då de ansåg att detta skapade trygghet och en känsla av kontroll. En central del i vården var kontinuitet och tillgänglighet samt kommunikation och information.

Copingstrategier vid bröstcancer : Ur ett patient- och familjeperspektivEn systematisk litteraturstudie

Syftet med denna systematiska litteraturstudie var att undersöka vilka copingstrategier som kvinnor med bröstcancer, deras partners och barn använde. De vetenskapliga artiklar som ligger till grund för litteraturstudiens resultat söktes på databaserna Elin@Dalarna, Wiley InterScience och PubMed. De valda artiklarnas vetenskaplighet granskades med modifierade versioner av Willman, Stoltz & Bahtsevani och Forsberg & Wengströms granskningsmallar. Resultatet av denna litteraturstudie visade att det fanns olika copingstrategier som användes för hantering av kvinnors bröstcancer. Flera studiers forskningsresultat visade att de copingstrategier som kvinnor med bröstcancer använde var religion, acceptans, att ha ett positivt synsätt, förnekelse, emotionellt stöd och undvikande. Ytterligare copingstrategier som kvinnor använde var socialt stöd, aktiva copingstrategier, planering, att ventilera sig, humor och att sysselsätta sig med olika aktiviteter samt att ha ett oskäligt beteende. De copingstrategier som förekom hos kvinnornas partners var gruppstöd och kommunikation. Barn till kvinnor med bröstcancer använde sig av religion, kommunikation och stöd samt undvikande som copingstrategier.
