- In the setting of prior myocardial infarction, the oral antiplatelet ticagrelor added to aspirin reduced the risk of recurrent ischemic events, especially, in those with diabetes mellitus. Patients with stable coronary disease and diabetes are also at elevated risk and might benefit from dual antiplatelet therapy. The Effect of Ticagrelor on Health Outcomes in diabEtes Mellitus patients Intervention Study (THEMIS, NCT01991795) is a Phase 3b randomized, double-blinded, placebo-controlled trial of ticagrelor vs placebo, on top of low dose aspirin. Patients >= 50 years with type 2 diabetes receiving anti-diabetic medications for at least 6 months with stable coronary artery disease as determined by a history of previous percutaneous coronary intervention, bypass grafting, or angiographic stenosis of >= 50% of at least one coronary artery were enrolled. Patients with known prior myocardial infarction (MI) or stroke were excluded. The primary efficacy endpoint is a composite of cardiovascular death, myocardial infarction, or stroke. The primary safety endpoint is Thrombolysis in Myocardial Infarction major bleeding. A total of 19 220 patients worldwide have been randomized and at least 1385 adjudicated primary efficacy endpoint events are expected to be available for analysis, with an expected average follow-up of 40 months (maximum 58 months). Most of the exposure is on a 60 mg twice daily dose, as the dose was lowered from 90 mg twice daily partway into the study. The results may revise the boundaries of efficacy for dual antiplatelet therapy and whether it has a role outside acute coronary syndromes, prior myocardial infarction, or percutaneous coronary intervention.

- Mate choice lies dose to differential reproduction, the engine of evolution. Patterns of mate choice consequently have power to direct the course of evolution. Here we provide evidence suggesting one pattern of human mate choice-the tendency for mates to be similar in overall desirability-caused the evolution of a structure of correlations that we call the d factor. We use agent-based models to demonstrate that assortative mating causes the evolution of a positive manifold of desirability, d, such that an individual who is desirable as a mate along any one dimension tends to be desirable across all other dimensions. Further, we use a large cross-cultural sample with n = 14,478 from 45 countries around the world to show that this d-factor emerges in human samples, is a cross-cultural universal, and is patterned in a way consistent with an evolutionary history of assortative mating. Our results suggest that assortative mating can explain the evolution of a broad structure of human trait covariation.

- Humans express a wide array of ideal mate preferences. Around the world, people desire romantic partners who are intelligent, healthy, kind, physically attractive, wealthy, and more. In order for these ideal preferences to guide the choice of actual romantic partners, human mating psychology must possess a means to integrate information across these many preference dimensions into summaries of the overall mate value of their potential mates. Here we explore the computational design of this mate preference integration process using a large sample of n = 14,487 people from 45 countries around the world. We combine this large cross-cultural sample with agent-based models to compare eight hypothesized models of human mating markets. Across cultures, people higher in mate value appear to experience greater power of choice on the mating market in that they set higher ideal standards, better fulfill their preferences in choice, and pair with higher mate value partners. Furthermore, we find that this cross-culturally universal pattern of mate choice is most consistent with a Euclidean model of mate preference integration.

- The objective was to outline results from our scientific studies on the associations among childhood behavior, adult personality, and biochemical factors in smoking habits. The studies consisted of: (1) follow-up of young criminals and controls, subdivided into risk for antisocial behavior groups, based on childhood rating levels of a projective test; and adult smoking habit groups; and (2) a large group of young adults examined on the same inventories. Personality in terms of KSP and EPQ-I scale scores, controlled for intelligence, indicated that the high and very high risk groups displayed significantly higher self-rated impulsiveness, anxiety, and nonconformity, as compared to the low risk group. Further, the very high risk group subjects, found to be overrepresented among subjects with heavy smoking habits, displayed lower mean platelet MAO-B activity and higher thyroid hormone levels than the low risk group. Thus, the higher the childhood risk for antisocial behavior, the clearer the adult personality pattern making subjects more disposed for smoking appeared; and the higher smoking habits, the stronger the relationships with biochemical measures. Results are discussed in terms of possible underlying mechanisms influencing personality and smoking habits.

Tidskriftsartikel (refereegranskat)abstract
- Background: Pain management in children after tonsil surgery is essential, and optimal pain treatment has been discussed for many years. Data from the National Tonsil Register in Sweden (NTRS) and a national mapping system have demonstrated the need for national pain treatment guidelines for pediatric tonsil surgery. As a result, Swedish national guidelines, together with updated patient information on the website tonsilloperation.se, were developed and implemented in 2013.Objectives The objective of this study was to evaluate the professionals’ opinions of and adherence to pain treatment guidelines for pediatric tonsil surgery patients in a two-year follow-up.Method: This descriptive cross-sectional study was based on data from an inter-professional questionnaire, which was validated by an expert group using a content validity index (S-CVI 0.93). The questionnaire was sent to all Swedish ear, nose and throat (ENT) departments (n=49) that the NTRS identified as performing tonsil surgery on children younger than 18 years of age. In each clinic, we asked for responses from staff in each of the following professions: ENT physicians, anesthesia physicians, registered nurse anesthetists, and registered nurses in the ENT departments.Results: Respondents from 48 ENT departments participated, and 139/163 (85%) completed questionnaires were returned. The guidelines were reported as being clear, ensuring patient safety and providing optimal pharmacological treatment. Treatment was given according to the guidelines: Half of the departments gave pre- or intraoperative treatment with clonidine, betamethasone and high-dose paracetamol (acetaminophen). A multimodal pain approach (paracetamol and COX inhibitors) after hospital discharge was prescribed by all departments after tonsillectomy and, more extensively, after tonsillotomy. One-third of the departments prescribed paracetamol with a higher normal dose for the first three postoperative days. Half of the departments prescribed rescue analgesics, clonidine or opioids after tonsillectomy. None of the departments prescribed codeine or tramadol, drugs that are discouraged in the guidelines. The majority of the departments used the website tonsilloperation.se to provide information to the patients and their caregivers.Conclusion: The respondents' opinions of and the ENT departments adherence to the Swedish national guidelines were considered to be good. The national implementation process in Sweden has impacted the manner in which ENT departments treat pain after tonsil surgery.

Adherence to Swedish Guidelines for Pain Treatment in Tonsil Surgery in Pediatric Patients
- 2016
-
Konferensbidrag (refereegranskat)abstract
- Objective: As shown by data from the National Tonsil Surgery Register in Sweden, tonsil surgery often causes severe pain that lasts for many days. The register data demonstrate the necessity for better evidence-based pain treatment guidelines for tonsil surgery. The guidelines, introduced in 2013, consist of both pharmacological and non-pharmacological recommendations. In the guidelines, a multimodal analgesic approach and combination of analgesics are recommended to provide effective pain treatment with limited side effects. Two national multi-professional education days on pain, pharmacology and the guidelines were offered. Web-based information about pharmacological treatment (www.tonsililloperation.se) was designed for patients and next-of-kin. The current aims were to describe adherence to the Swedish guidelines for pain treatment in tonsil surgery in pediatric patients < 18 yearsMethod: An inter-professional questionnaire was developed, including questions linked to the relevant guidelines. The questions came from a national mapping before the guidelines were designed. The items were discussed by an expert group, and content validity was evaluated using the content validity index.ENT-and anesthesia physicians and nurses from all 50 ENT clinics in Sweden were enrolled.Results: Most clinics had received the guidelines, but there was a discrepancy between the professions. More than half had perused the literature review performed before the guidelines were designed, and attended themulti-professional education day. Pre- and perioperative treatment usually included paracetamol, clonidine and betamethasone. A multimodal pain approach after discharge from hospital (tonsillectomy and tonsillotomy) was used, combining paracetamol with cox-inhibitors. Most clinics used paracetamol, with a higher dose for the first 3 days (healthy children and acceptable nutrition), and a reduced dose from day 4.In case of inadequate analgesia after tonsillectomy, oral clonidine or opioids were used. Several clinics followed the recommendation to use clonidine as first choice and secondly an opioid. No respondents prescribed codeine compared to 80% at the mapping before the guidelines were designed. The guidelines were experienced as clear, safe and sufficient. The web-based information was used by most of the clinics to improve quality of care and provide facilitating tools for patients, relatives and caregivers.Conclusion: Swedish guidelines for tonsil surgery provide practical evidence-based pain treatment recommendations. To achieve a change, multi-professional education is necessary. This needs to be repeated for a wider spread.Future research should include evaluation through pain diaries and questionnaires to next-of-kin and children. There should be matching of data from the quality registers at each clinic, with pain variables such as unplanned health care contacts due to pain, number of days with analgesics, and return to normal diet

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis focuses on the changed governance of the public sector and what it can entail for professional work in substance abuse treatment. The point of departure is one of these new forms of governing, namely ‘knowledge governance’, which refers to a policy-driven process for promoting the use of evidence-based practice. The overall aim is to contribute to understanding and knowledge of the meaning and the conditions for knowledge governance in substance abuse treatment. The thesis studies how knowledge is interpreted by professionals and adapted to local practice in relation to organizational and professional conditions. The thesis also highlights the implications that these conditions may have for knowledge development on a professional and organizational level. The empirical material comprises three studies. Study 1 included a document analysis and a literature review. The document analysis examines how knowledge governance is described in official documents, while the focus of the literature review is on the concept of knowledge management. In Studies 2 and 3 focus group interviews were conducted with professionals who participated in a specific project, and professionals who use structured interview methods in their work (Addiction Severity Index, ASI, or Documentation of clients, DOC). The theoretical perspectives used in the thesis are neo-institutional theory, professional theory and perspectives on workplace learning. The results of Study 1 showed that knowledge governance embodies a steering of organizations, in comparison with knowledge management as a means for steering in organizations. The analyses from the focus group interviews demonstrate that knowledge governance becomes the subject of translations and edits to a local context. This process was affected by both organizational and professional conditions. The thesis is concluded with a discussion of the conditions that must be present if knowledge governance can lead to development of knowledge. The main result is that strategies must be tailored to each organization's specific condition and must be anchored throughout the organization.

Tidskriftsartikel (refereegranskat)abstract
- During a routine scan for Signal Recognition Particle (SRP) RNAs in eukaryotic sequences, we surprisingly found in silico evidence in GenBank for a 265-base long SRP RNA sequence in the ITS1 region of a total of 11 fully identified species in three ectomycorrhizal genera of the Basidiomycota (Fungi): Astraeus, Russula, and Lactarius. To rule out sequence artifacts, one specimen from a species indicated to have the SRP RNA-containing ITS region in each of these genera was ordered and re-sequenced. Sequences identical to the corresponding GenBank entries were recovered, or in the case of a non-original but conspecific specimen differed by three bases, showing that these species indeed have an SRP RNA sequence incorporated into their ITS1 region. Other than the ribosomal genes, this is the first known case of non-coding RNAs in the eukaryotic ITS region, and it may assist in the examination of other types of insertions in fungal genomes.

- First passage percolation on is a model for describing the spread of an infection on the sites of the square lattice. The infection is spread via nearest neighbor sites and the time dynamic is specified by random passage times attached to the edges. In this paper, the speed of the growth and the shape of the infected set is studied by aid of large-scale computer simulations, with focus on continuous passage time distributions. It is found that the most important quantity for determining the value of the time constant, which indicates the inverse asymptotic speed of the growth, is , where are i.i.d. passage time variables. The relation is linear for a large class of passage time distributions. Furthermore, the directional time constants are seen to be increasing when moving from the axis towards the diagonal, so that the limiting shape is contained in a circle with radius defined by the speed along the axes. The shape comes closer to the circle for distributions with larger variability.
