Systematisk litteraturstudie, SLS: - metodeanvisning til brug på professionsbachelorstudier

  Today, large amounts of scientific knowledge are available nationally and internationally. This knowledge can form the basis for an assignment in the professional bachelor programs. There is a growing need for methodological knowledge of how to review scientific literature. Therefore, it is relevant for you as a bachelor student to be able to master review methods. There are various methods for making literature-based studies but some are extremely complex. The purpose of this text is to describe step-by-step the Systematic Literature Studies, also called an SLS. The method has a content, which makes the method relevant to you as a bachelor student. All the methods for literature-based tasks have some common features. Method authors describe in detail how literature is sought and assessed, but it is difficult to see how the literature is analyzed and how the findings can be presented, the latter is therefore in focus in this article. In the article, it is discussed and decided what is to be included as empirical data in the SLS, and inductive and deductive approaches to research will be presented. The article refers continuously to method literature where you can read more about what has inspired the development of the SLSmetho

Approaching patients with hyperreflectivity and perplexity:An empirical qualitative investigation

Abstract Objective Perplexity and hyperreflectivity are considered important aspects of self-disorders in patients with schizophrenia, yet knowledge of the appropriate psychotherapy for these patients is sparse. We aimed to explore how phenomenological psychologists or psychiatrists described their approach to these patients and their own emotional response when hyperreflectivity and perplexity emerged in therapy or consultations. Methods Four e-mail interviews with experienced clinical researchers within the field of phenomenology and schizophrenia were examined using a double hermeneutic qualitative analysis. Results The informants offered reassurance by authority and the encouragement of sharing of experiences interlaced in the beginning of therapy. Later they went on relating expressions of hyperreflectivity and perplexity to emotions, life events and goals. They described feelings of admiration and professional recognition along with worry, insecurity and sadness. Conclusion The list of primary themes covers what might seem very basic therapeutic interventions. However, the careful and open-minded manner in which these were carried out was noteworthy. The double task of staying closely attuned to the patient’s airy reflections and, at the same time, when the patient was ready for it, carefully making links to domains of the patient’s everyday life, was clearly molded to patients with fragile attachment

Effekt av surfôr fra kortvarig eng eller langvarig eng på kvalitet i kumelk

Surfôr fra kortvarig eng har gitt høyere andel av flerumettede fettsyrer i melk sammenlignet med surfôr fra langvarig eng men dette har ikke ført til at melka ble mer utsatt for lysindusert oksidasjon. Tilskudd av α-tokoferol økte innholdet av α-tokoferol i melka men hadde ingen effekt på melkas oksidative stabilitet. Surfôr fra kortvarig eng ga høyere innhold av isoflavoner og lavere innhold av lignaner i melk enn surfôr fra langvarig eng

Bacterial community structure in High-Arctic snow and freshwater as revealed by pyrosequencing of 16S rRNA genes and cultivation

The bacterial community structures in High-Arctic snow over sea ice and an ice-covered freshwater lake were examined by pyrosequencing of 16S rRNA genes and 16S rRNA gene sequencing of cultivated isolates. Both the pyrosequence and cultivation data indicated that the phylogenetic composition of the microbial assemblages was different within the snow layers and between snow and freshwater. The highest diversity was seen in snow. In the middle and top snow layers, Proteobacteria, Bacteroidetes and Cyanobacteria dominated, although Actinobacteria and Firmicutes were relatively abundant also. High numbers of chloroplasts were also observed. In the deepest snow layer, large percentages of Firmicutes and Fusobacteria were seen. In freshwater, Bacteroidetes, Actinobacteria and Verrucomicrobia were the most abundant phyla while relatively few Proteobacteria and Cyanobacteria were present. Possibly, light intensity controlled the distribution of the Cyanobacteria and algae in the snow while carbon and nitrogen fixed by these autotrophs in turn fed the heterotrophic bacteria. In the lake, a probable lower light input relative to snow resulted in low numbers of Cyanobacteria and chloroplasts and, hence, limited input of organic carbon and nitrogen to the heterotrophic bacteria. Thus, differences in the physicochemical conditions may play an important role in the processes leading to distinctive bacterial community structures in High-Arctic snow and freshwater

The difficult medical emergency call:A register-based study of predictors and outcomes

BACKGROUND: Pre-hospital emergency care requires proper categorization of emergency calls and assessment of emergency priority levels by the medical dispatchers. We investigated predictors for emergency call categorization as “unclear problem” in contrast to “symptom-specific” categories and the effect of categorization on mortality. METHODS: Register-based study in a 2-year period based on emergency call data from the emergency medical dispatch center in Copenhagen combined with nationwide register data. Logistic regression analysis (N = 78,040 individuals) was used for identification of predictors of emergency call categorization as “unclear problem”. Poisson regression analysis (N = 97,293 calls) was used for examining the effect of categorization as “unclear problem” on mortality. RESULTS: “Unclear problem” was the registered category in 18% of calls. Significant predictors for “unclear problem” categorization were: age (odds ratio (OR) 1.34 for age group 76+ versus 18–30 years), ethnicity (OR 1.27 for non-Danish vs. Danish), day of week (OR 0.92 for weekend vs. weekday), and time of day (OR 0.79 for night vs. day). Emergency call categorization had no effect on mortality for emergency priority level A calls, incidence rate ratio (IRR) 0.99 (95% confidence interval (CI) 0.90–1.09). For emergency priority level B calls, an association was observed, IRR 1.26 (95% CI 1.18–1.36). DISCUSSIONS: The results shed light on the complexity of emergency call handling, but also implicate a need for further improvement. Educational interventions at the dispatch centers may improve the call handling, but also the underlying supportive tools are modifiable. The higher mortality rate for patients with emergency priority level B calls with “unclear problem categorization” could imply lowering the threshold for dispatching a high level ambulance response when the call is considered unclear. On the other hand a “benefit of the doubt” approach could hinder the adequate response to other patients in need for an ambulance as there is an increasing demand and limited resources for ambulance services. CONCLUSIONS: Age, ethnicity, day of week and time of day were significant predictors of emergency call categorization as “unclear problem”. “Unclear problem” categorization was not associated with mortality for emergency priority level A calls, but a higher mortality was observed for emergency priority level B calls
