- Introduction: Bacteraemia is a first stage for patients risking conditions such as septic shock. The primary aim of this study is to describe factors in the early chain of care in bacteraemia, factors associated with increased chance of survival during the subsequent 28 days after admission to hospital. Furthermore, the long-term outcome was assessed. Methods: This study has a quantitative design based on data from Emergency Medical Services (EMS) and hospital records. Results: In all, 961 patients were included in the study. Of these patients, 13.5% died during the first 28 days. The EMS was more frequently used by non-survivors. Among patients who used the EMS, the suspicion of sepsis already on scene was more frequent in survivors. Similarly, EMS personnel noted the ESS code "fever, infection" more frequently for survivors upon arriving on scene. The delay time from call to the EMS and admission to hospital until start of antibiotics was similar in survivors and non-survivors. The five-year mortality rate was 50.8%. Five-year mortality was 62.6% among those who used the EMS and 29.5% among those who did not (p < 0.0001). Conclusion: This study shows that among patients with bacteraemia who used the EMS, an early suspicion of sepsis or fever/infection was associated with improved early survival whereas the delay time from call to the EMS and admission to hospital until start of treatment with antibiotics was not. 50.8% of all patients were dead after five years.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- The term green infrastructure captures the need to conserve biodiversity and to sustain landscapes’ different ecosystem services. Maintaining green infrastructures through protected areas, management and landscape restoration requires knowledge in geography, spatial data about biophysical, anthropogenic and immaterial values, spatial comprehensive planning, and thus geographical information systems (GIS). To understand land use planning practices and planning education regarding GIS in Sweden we interviewed 43 planners and reviewed 20 planning education programmes. All planners used GIS to look at data but did not carry out spatial analyses of land covers. BSc programmes included more GIS than MSc programmes but very few taught analyses for spatial planning. As key spatial planning actors, municipalities’ barriers and bridges for improved GIS use for collaborative learning about green infrastructures are discussed. A concluding section presents examples of how GIS can support spatial planning for green infrastructures.

Tidskriftsartikel (refereegranskat)abstract
- A diagnosis-prescribing study was performed in 5 Swedish counties during 1 week in November in 2000 and repeated in 2002. The aim of the present study was to analyse data for children 0-15y of age who consulted a general practitioner with symptoms of an infection. During the 2 weeks studied, 4049 children were consulted. Respiratory tract infections (RTI) were the predominant diagnoses, above all among the youngest children, while the proportion of urinary tract infections and skin infections increased with increasing age. Between the y 2000 and 2002, the proportion of children allocated the diagnosis streptococcal tonsillitis and pneumonia decreased (p<0.01 and p<0.001, respectively) while the proportion of common cold increased (p<0.001). Antibiotic prescribing decreased from 55% to 48% (p<0.001) for respiratory infections between the years studied. The only significant changes in type of antibiotics prescribed were the increase of isoxazolylpenicillins (p<0.001) used for skin infection and the decrease of macrolides (p=0.001). A diagnostic test was used in more than half of the consultations. Of children allocated a RTI diagnosis, 36% were prescribed antibiotics when a C-reactive protein test was performed compared to 58% in those not tested. Further studies are needed in general practice to determine the optimal use of near-patient tests in children with RTI.

- Objective: To compare the effects of a bolus of milrinone, 50 mu g/kg, versus placebo on flow in coronary artery bypass grafts after cardiopulmonary bypass (CPB). Design: A prospective, randomized, double-blind study. Setting: A university hospital. Participants: Forty-four patients with stable angina and left ventricular ejection fraction > 30% scheduled for elective coronary artery bypass graft (CABG) surgery were included. Intervention: Patients were randomized to receive 50 mu g/kg of milrinone (n = 22) or placebo (n = 22) after aortic declamping. Measurements and Main Results: The flow in coronary artery bypass grafts was measured with a transit time flow meter at 10 minutes and 30 minutes after termination of CPB. The hemodynamic evaluation included transesophageal echocardiography, mean arterial pressure (MAP), heart rate, and intracavitary measurement of left ventricular end-diastolic pressure (LVEDP). The flow in the saphenous vein grafts was significantly higher in the milrinone group when compared with the placebo group both at 10 and 30 minutes after termination of CPB (p < 0.001). At 10 minutes, the flow was 64.5 +/- 37.4 mL/min (mean +/- standard deviation) and 43.6 +/- 25.7 mL/min in nonsequential vein grafts for milrinone and placebo, respectively. Corresponding values at 30 minutes were 54.8 +/- 29.9 mL/min and 35.3 +/- 22.4 mL/min. The left internal thoracic artery (LITA) flow was higher in the milrinone group but did not reach statistical significance. The fractional area change was higher, and the MAP and calculated pressure gradient (MAP-LVEDP) were lower at 10 minutes in the milrinone group. Conclusion: Milrinone significantly increases the flow in anastomosed saphenous vein grafts after CPB, and has beneficial effects on left ventricular function.

Konferensbidrag (refereegranskat)abstract
- Projektet hade som mål att introducera ett simuleringsprogram redan i andra årskursen. Initiativet kom ursprungligen från utbildningsnämnden för Bioteknik och Kemiteknik, som startade ett antal beräkningsteknikprojekt för att stärka teknologerna färdigheter i beräkningsteknik. Projektet genomfördes av 11 frivilliga (av 108) ”testpiloter” i kursen Transportprocesser. Vi ersatte ett av de tre beräkningsprojekten, som normalt ingår i kursen, med ett Femlab-projekt (numera Comsol Multiphysics). Med detta kan man simulera tämligen avancerade strömningsförlopp. Projektet var mycket lyckosamt. De som gjorde detta projekt uppnådde samma insikt i strömningslära som övriga men på ett helt annat sätt – och dessutom genom att jobba helt på egen hand. Resultatet visar också att användningen av ”learning outcomes” eller ”läranderesultat”, som ett sätt att formulera kursmål, faktiskt kan innebära att vi kan se fler möjligheter att genomföra kurser på.

Context : The abstract term for the concrete
- 2016
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis deals with the term 'context' and the aim has been to reason about the term in order to see whether it is possible to reach a satisfactory understanding of the concept. But the thesis is also a journey into human reasoning and conveys a certain view of human cognition. It aims to synthesise results of studies within psychology, cognitive science, anthropology, and human-computer interaction. My understanding is that context is not something we are a part of, but rather something we create mentally in relation a specific goal. Determination of something ambiguous thus comes from top-down processes related to a goal. I believe context has been wrongly interpreted in HCI as that which a user is situated in and which a product is being used in. I suggest instead a separation between the user environment and the user context.

Knowledge elicitation as abstraction of purposive behaviour
- 2019
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Researchers use knowledge elicitation methods to document expert knowledge for the primary purpose of understanding cognitive processes and with this understanding, technical solutions to resolve human factors issues can be produced. This dissertation offers a novel perspective on knowledge elicitation as an abstraction process. Such a theoretical framework has emerged by consolidating the ecological approach of Brunswikian psychology with the ideas of tacit and personal knowledge of Polanyian epistemology. Traditionally, knowledge elicitation has been considered an extraction process in which knowledge can be readily transferred from one individual to another. Here, this traditional position is rejected in favour of Polanyi’s premise that much of the knowledge individuals possess is tacit in nature, which implies that it cannot be documented easily, expressed in explicit form or explained. In this dissertation, knowledge is characterised as a personal process of knowing, highlighting context as a subjective knowledge structure of personal experiences that is formulated implicitly and indirectly over time through a dynamic interaction with the environment. Therefore, tacit knowledge cannot be articulated or shared; however, learners can be inspired by observing other individuals' purposive (i.e., goal-directed) behaviours and thus shape their own tacit knowledge once they practise the observed skills and develop conceptual understanding through reasoning about the learning process. Knowledge elicitation thereby makes use of observations, questions, or more structured process tracing methods in environments familiar to the observed individuals to elicit purposive behaviour from them. Accordingly, functional descriptions can be produced in this process that further conceptual understanding of a particular domain. Knowledge elicitation procedures are a powerful set of methods for reaching such functional descriptions. Moreover, by understanding the resulting knowledge elicitation data as an abstraction derived from multiple collection points in the same environment, the focus shifts from purely subjective mental constructs to the impact of environmental constraints.
