- BACKGROUND: Multivariable prediction models are used in oral health care to identify individuals with an increased likelihood of caries increment. The outcomes of the models should help to manage individualized interventions and to determine the periodicity of service. The objective was to review and critically appraise studies of multivariable prediction models of caries increment.METHODS: Longitudinal studies that developed or validated prediction models of caries and expressed caries increment as a function of at least three predictors were included. PubMed, Cochrane Library, and Web of Science supplemented with reference lists of included studies were searched. Two reviewers independently extracted data using CHARMS (Critical Appraisal and Data Extraction for Systematic Reviews of Prediction Modelling Studies) and assessed risk of bias and concern regarding applicability using PROBAST (Prediction model Risk Of Bias ASessment Tool). Predictors were analysed and model performance was recalculated as estimated positive (LR +) and negative likelihood ratios (LR -) based on sensitivity and specificity presented in the studies included.RESULTS: Among the 765 reports identified, 21 studies providing 66 prediction models fulfilled the inclusion criteria. Over 150 candidate predictors were considered, and 31 predictors remained in studies of final developmental models: caries experience, mutans streptococci in saliva, fluoride supplements, and visible dental plaque being the most common predictors. Predictive performances varied, providing LR + and LR - ranges of 0.78-10.3 and 0.0-1.1, respectively. Only four models of coronal caries and one root caries model scored LR + values of at least 5. All studies were assessed as having high risk of bias, generally due to insufficient number of outcomes in relation to candidate predictors and considerable uncertainty regarding predictor thresholds and measurements. Concern regarding applicability was low overall.CONCLUSIONS: The review calls attention to several methodological deficiencies and the significant heterogeneity observed across the studies ruled out meta-analyses. Flawed or distorted study estimates lead to uncertainty about the prediction, which limits the models' usefulness in clinical decision-making. The modest performance of most models implies that alternative predictors should be considered, such as bacteria with acid tolerant properties.TRIAL REGISTRATION: PROSPERO CRD#152,467 April 28, 2020.

Managing Medical Emergency Calls
- 2016
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This dissertation is a conversation analytic examination of recurrent practices of interaction in medicalemergency calls. The study expands the analytical focus in past research on emergency calls betweenemergency call operators and callers to pre-hospital emergency care interaction on the phone betweennurses, physicians and callers. The investigation is based on ethnographic fieldwork in a Swedish emergencycontrol centre. The data used for the study consists primarily of audio recordings of medical emergency calls.Fundamental procedures in medical emergency calls examined in the dissertation are: (1) questioning; (2)emotion management; (3) risk management and (4) instruction giving. Emergency call-takers ask questions toelicit descriptions by callers of what is happening and to manage symptoms of patients to help keep them safeuntil ambulance crews arrive. In the questioning practice about acutely ill or injured patients call-takers usemainly yes-no questions and clarify problems by questioning callers making a distinction between defined andundefined problems. The analysis reveals four core types of emotion management practices: (1) call-takerskeep themselves calm when managing callers’ social displays of emotions; (2) promising ambulanceassistance; (3) providing problem solving presentations including emergency response measures to concernsof callers, and (4) emphasising the positive to create hope for callers. Call-takers use seven key procedures tomanage risk in medical emergency calls: (1) risk listening through active listening after actual and possiblerisks; (2) risk questioning; (3) risk identification; (4) risk monitoring; (5) risk assessment; (6) making decisionsabout elicited risk and (7) risk reduction. Instruction giving using directives and recommendations isaccomplished by call-takers in four main ways: (1) acute flow maintaining instruction giving when callers areprocedurally out of line; (2) measure oriented instructions for patient care and emergency responsemanagement; (3) organisational response instructions and (4) summarising instruction giving. Callers routinelyacknowledge risk identifications and follow instructions delivered by call-takers to examine statuses and lifesigns of patients such as breathing, movement and pulse, and perform basic first aid and emergency responsemeasures.The findings generated from this study will be useful in emergency call-taker training in carrying out interactiveprocedures in medical emergency calls and add to the larger research programmes on on-telephoneinteraction between professionals and citizen callers. This is an essential book for pre-hospital emergency careproviders and institutional interaction researchers and students.

Innovation and regional transformation : From clusters to new combinations
- 2010
-
Bok (övrigt vetenskapligt/konstnärligt)abstract
- In summary, this book considers the conditions for a future innovation policy in Skåne from two perspectives. Firstly, from the existing economic structure; and secondly, from the experience gained from initiatives already in place. With a common theoretical understanding of the problem area, the book integrates a number of methodologically different approaches. Such a combination of methods is rare, yet provides a deeper understanding of the nature of the economy, of how the various sectors and industries are related to each other in terms of skills, and of how development initiatives for the various industries or clusters work. Theoretical discussions are intertwined with empirical observations of Skåne’s economy. In this way, the book is an introduction to contemporary innovation and policy literature, as well as a more specific discussion and decision basis for actors involved in the economy and policy of both Skåne and Sweden.

Socio-technical IS design science research : developing design theory for IS integration management
- 2011
-
Ingår i: Information Systems and E-Business Management. - : Springer Science and Business Media LLC. - 1617-9846 .- 1617-9854. ; 9:1, s. 109-131

Tidskriftsartikel (refereegranskat)abstract
- Design science research is an essential part of IS research since the field should not only try to understand how the world is, but also how to change it. We argue that the aim of IS design science research should be to develop practical knowledge not only for the design of novel information technology (IT), but also for IS governance and management. Whereas at least some methodological support exists for researchers engaged in IT-centric design science research, limited support is available for researchers who want to develop design knowledge and theory for IS governance and management. To overcome this shortcoming, we suggest a socio-technical IS design science research approach. The approach has four main activities: (1) identifying problem situations and desired outcomes, (2) reviewing extant theories, knowledge and data, (3) proposing/refining design theory and knowledge, and (4) testing design theory and knowledge. The applicability and usefulness of the proposed approach is shown by means of a design science research project concerning IS integration management in the context of mergers and acquisitions.

Use of Scandinavian Moist Smokeless Tobacco (Snus) and the Risk of Atrial Fibrillation
- 2014

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Snus is a smokeless tobacco product, widely used among Swedish men and increasingly so elsewhere. There is debate as to whether snus is an acceptable "harm-reduction" tobacco product. Since snus use delivers a dose of nicotine equivalent to cigarettes, and has been implicated in cardiac arrhythmia because of associations with sudden cardiovascular death, a relation with atrial fibrillation is plausible and important to investigate.METHODS:: To assess the relation between use of snus and risk of atrial fibrillation, we carried out a pooled analysis of 7 prospective Swedish cohort studies. In total, 274,882 men, recruited between 1978 and 2004, were followed via the National Patient Register for atrial fibrillation. Primary analyses were restricted to 127,907 never-smokers. Relative risks were estimated using Cox proportional hazard regression.RESULTS:: The prevalence of snus use was 25% among never-smokers. During follow-up, 3,069 cases of atrial fibrillation were identified. The pooled relative risk of atrial fibrillation was 1.07 (95% confidence interval = 0.97-1.19) in current snus users, compared with nonusers.CONCLUSION:: Findings from this large national pooling project indicate that snus use is unlikely to confer any important increase in risk of atrial fibrillation.

Transgression in contemporary media culture
- 2021

Ingår i: International journal of cultural studies. - : Sage Publications. - 1367-8779 .- 1460-356X. ; 24:1, s. 3-14

Tidskriftsartikel (refereegranskat)abstract
- This is the introduction to a special issue on media and transgression, one of early cultural studies’ key terms. It inquires into the uses of transgression as a critical concept to query contemporary media culture which is discussed in six case studies: on political satire, Mukbang, cult drama, the policing of film piracy, media scandals, and online trolls. Transgression points to the energy that fuels the media ecology – from content and content production to audience practices and the policing of content ownership. It is the (conscious) overstepping of moral and legal boundaries, that challenges written and unwritten rules. The frisson of rule breaking and the reward of rule re-establishment (whether by powerful parties or everyday gossip) are transgression’s bookends. Together they support the cyclical rhythm of media culture that maintains not just our interest as viewers but our interests and connectedness as citizens, whether in celebration, outrage or condemnation.

Validity and Reliability of the Occupational Balance Questionnaire (OBQ11) in a U.S. Sample of Adults With Type 1 Diabetes
- 2023

Ingår i: American Journal of Occupational Therapy. - : American Occupational Therapy Association. - 0272-9490 .- 1943-7676. ; 77:4

Tidskriftsartikel (refereegranskat)abstract
- IMPORTANCE: Although occupational balance (OB) is a construct of importance to occupational therapy, existing OB assessments have not been validated in clinical populations.OBJECTIVE: To examine the validity and reliability of the 11-item version of the Occupational Balance Questionnaire (OBQ11) in U.S. adults with Type 1 diabetes.DESIGN: Data were analyzed from adults with Type 1 diabetes enrolled in a larger longitudinal study examining the relationships among blood glucose, emotion, and functioning. Dimensionality of the OBQ11 was assessed with item response theory (IRT); convergent validity was tested by examining whether associations between the OBQ11 and other constructs were consistent with a priori hypotheses.SETTING: Three outpatient clinical sites in the United States.PARTICIPANTS: Data from 208 U.S. adults with Type 1 diabetes were included in the analyses (42% Latino, 29% White, 14% African American, 7% multiethnic, and 8% other).OUTCOMES AND MEASURES: Assessments administered include the OBQ11, Patient Health Questionnaire (depression), and Diabetes Self-Management Questionnaire.RESULTS: Overall, results from IRT models and correlational tests supported the reliability and validity of the OBQ11. For instance, higher scores on the OBQ11 were significantly associated with better self-ratings of diabetes management behaviors (r = .28, p < .001), lower depression symptoms (r = -.53, p < .001), and greater positive affect (r = .32, p < .001). A single-factor generalized partial credit model fit the OBQ11 acceptably well, supporting its unidimensionality.CONCLUSIONS AND RELEVANCE: The OBQ11 may be a reliable and valid measure of OB appropriate for use in clinical populations such as adults with diabetes. What This Article Adds: OB is not often formally assessed by occupational therapists in the United States, even though the contributions of OB to health and well-being are core components of the philosophy of occupational therapy. The current evidence supports the validity of the OBQ11 in a clinical population of adults with Type 1 diabetes and demonstrates significant associations between OB and health management behaviors. Study results may encourage greater consideration and assessment of OB in occupational therapy clinical practice in the United States.
