- Purpose To investigate potential associations between preoperative MRI findings and patient reported outcome measures (PROMs) after surgery for lumbar spinal stenosis (LSS). Methods The NORDSTEN trial included 437 patients. We investigated the association between preoperative MRI findings such as morphological grade of stenosis (Schizas grade), quantitative grade of stenosis (dural sac cross-sectional area), disc degeneration (Pfirrmann score), facet joint tropism and fatty infiltration of the multifidus muscle, and improvement in patient reported outcome measures (PROMs) 2 years after surgery. We dichotomized each radiological parameter into a moderate or severe category. PROMs i.e., Oswestry Disability Index (ODI), Zurich Claudication Questionnaire (ZCQ) and Numeric rating scale (NRS) for back and leg pain were collected before surgery and at 2 year follow-up. In the primary analysis, we investigated the association between MRI findings and ODI score (dichotomized to >= 30% improvement or not). In the secondary analysis, we investigated the association between MRI findings and the mean improvement on the ODI-, ZCQ- and NRS scores. We used multivariable regression models adjusted for patients' gender, age, smoking status and BMI. Results The primary analysis showed that severe disc degeneration (Pfirrmann score 4-5) was significantly associated with less chance of achieving a 30% improvement on the ODI score (OR 0.54, 95% CI 0.34, 0.88). In the secondary analysis, we detected no clinical relevant associations. Conclusion Severe disc degeneration preoperatively suggest lesser chance of achieving 30% improvement in ODI score after surgery for LSS. Other preoperative MRI findings were not associated with patient reported outcome.

- In this chapter, the history of evidence-based care and practice and their main principles will be presented, including a special focus on the field of obstetrics and midwifery. We will describe and discuss the main components of evidence-based midwifery and how they have been applied on important topics within maternal and newborn care. Finally, we will discuss the opportunities and challenges that midwives in the Nordic countries face when applying evidence-based care in a clinical setting that is dominated by large obstetric wards.

Early repolarization in ECG. Definition, prevalence and prognostic significance
- 2015

Ingår i: Läkartidningen. - 0023-7205. ; 112

Tidskriftsartikel (refereegranskat)abstract
- Early repolarization defined as antero-lateral ST-segment elevation exists in 1-2 % of the general population and has been considered a benign ECG finding for decades. However, early repolarization, defined as infero-lateral J-waves, has in recent studies been associated with an increased - albeit low - risk of sudden and cardiovascular death. This ECG pattern is present in 3-13% of the general population. However, exercise training can induce all types of early repolarization, and the prevalence in the athletic population rises to 20-90%. There is large variability between sports (higher in endurance athletes) and also throughout the season (higher during times of peak fitness). In athletes, early repolarization, regardless of type, is considered benign. In asymptomatic non-athletes, the absolute risk is too low to use this ECG finding in clinical practice. In individuals with J-wave syndrome, on the other hand, ICD implantation should be strongly considered to prevent sudden cardiac death.

- Purpose: This study aimed to assess the prevalence and patterns of early repolarization (ER) in middle-age long-distance runners, its relation to cardiac structure and function, and its response to strenuous physical activity. Methods: Male first-time cross-country race participants >45 yr were assessed pre-and postrace by medical history and physical examination, 12-lead ECG, vectorcardiography, blood tests, and echocardiography. ER was defined either as ST elevation or J wave and categorized according to localization and morphology. Results: One hundred and fifty-one subjects (50 +/- 5 yr) were evaluated before the race, and 47 subjects were evaluated after the race. Altogether, 67 subjects (44%) had ER. Subjects with versus without ER had a lower resting HR (56 +/- 8 vs 69 +/- 9 bpm, P = 0.02), lower body mass index (24 +/- 2 vs 25 +/- 3 kg.m(-2), P < 0.001), higher training volume (3.0 +/- 2.6 vs 2.1 +/- 2.7 h.wk(-1), P = 0.03), and faster 30-km running times (194 +/- 28 vs 208 +/- 31 min, P = 0.01). Vectorcardiography parameters in subjects with ER showed more repolarization heterogeneity: vector gradient (QRS-T-area) (120 +/- 25 vs 92 +/- 29 mu Vs, P < 0.001), T-area (105 +/- 18 vs 73 +/- 23 mu Vs, P < 0.001), and T-amplitude (0.63 +/- 0.13 vs 0.53 +/- 0.16 mm, P < 0.001); these parameters were inversely related to HR (r = -0.37 to -0.48, P < 0.001). ER disappeared in 15 (75%) of 20 subjects after the race. Conclusions: ER is a common finding in middle-age male runners. This ECG pattern, regardless of morphology and localization, is associated with normal cardiac examinations including noninvasive electrophysiology, features of better physical conditioning, and disappears after strenuous exercise in most cases. These findings support that ER should be regarded as a common and training-related finding also in middle-age physically active men.

- Purpose: The objective of this study is to investigate the time course of autonomic tone changes after a first-time endurance running race participation and associations with postexertional high-sensitivity troponin (hsTnT) levels in middle-aged males. Methods: Male (n = 42) first-time long-distance running race (Lidingoloppet 30 km) participants >= 45 yr (50.5 +/- 5) were examined. HR and HR variability (HRV) in the time domain (SDANN) was measured continuously from 2 d before to 4 d after the race using a wireless cardiovascular monitor that also recorded arrhythmia episodes. In addition, subjects were assessed pre- and postrace by medical history and physical examination, 12-lead ECG, blood tests including hsTnT, and echocardiography. Results: Compared with corresponding prerace values, nighttime (2: 00-4: 00 a.m.) HR was significantly elevated (63.6 +/- 9.4 vs 53.9 +/- 8.3 bpm, P < 0.001) on the first night postrace, whereas HRV remained reduced for a median of 64 h (interquartile range, 51-102 h). A prolonged HR recovery period (r = 0.48, P = 0.005) and a larger reduction in postrace HRV (r = -0.49, P = 0.003) correlated with higher postrace hsTnT levels. The association between reduced HRV and higher hsTnT remained significant after multivariate analysis (A = -0.48, P = 0.01). No sustained ventricular arrhythmias were recorded, but atrial fibrillation occurred in two subjects. Conclusion: Endurance running race participation caused a prolonged alteration of autonomic tone. More marked and prolonged changes were associated with higher levels of hsTnT, suggesting that the magnitude of troponin increase after strenuous exercise may reflect the magnitude of exercise-induced cardiovascular stress.

- Abstract PURPOSE: To assess the cardiovascular health and risk profile in middle-aged males making an entry to participate for their first time in a long-distance race. METHODS: Male first-time participants ≥45 years in the world's largest cross-country running race, the Lidingöloppet, were evaluated with a medical history and physical exam, European risk-SCORE, 12-lead ECG, echocardiography and blood tests. Further diagnostic work-up was performed when clinically indicated. RESULTS: Of 265 eligible runners, 153 (58%, age 51±5 y) completed the study. While the 10-year fatal cardiovascular event risk was low (SCORE: 1% (IQR: 0 - 1%)), mild abnormalities were common, e.g. elevated blood-pressure (19%), left ventricular hypertrophy (6%), elevated LDL cholesterol (5%). ECG changes compatible with "athlete's heart" were present in 82%, e.g. sinus bradycardia (61%) and/or early repolarization (32%). ECG changes considered training-unrelated were found in 24%, e.g. prolonged QTc: 13%; left axis deviation: 5.3%; left atrial enlargement: 4%). In 14 runners (9%) additional diagnostic work-up was clinically motivated, and 4 (2%) were ultimately discouraged from vigorous exercise due to QTc intervals >500 ms (n=2), symptomatic atrioventricular block (n=1), and a cardiac tumor (n=1). The physician exam and the ECG identified 12 of the 14 subjects requiring further evaluation. CONCLUSIONS: Cardiovascular evaluation of middle-aged men, including a physician exam and a 12-lead ECG, appears useful to identify individuals requiring further testing prior to vigorous exercise. The additional yield of routine echocardiography was small.

- Purpose This paper aims to expand the emerging field of symbolic green consumer behavior (GCB) by investigating the impact of anticipated conspicuousness of the consumption situation on consumers’ choice of organic products. In addition, the paper also explores whether self-monitoring ability and attention to social comparison information (ATSCI) influence GCB in situations of anticipated high conspicuousness. Design/methodology/approach Two experiments test the study’s hypotheses. Findings The results of both experiments show that the anticipation of conspicuousness has a significant effect on GCB. Moreover, in Experiment 2, this effect is moderated by consumers’ level of ATSCI but not by their self-monitoring ability. Research limitations/implications Because ATSCI significantly interacts with green consumption because of the anticipation of a conspicuous setting, although self-monitoring ability does not, we conclude that social identification is an important determinant of green consumption. Practical implications Marketers who focus on building green brands could consider designing conspicuous consumption situations to increase GCB. Social implications Policymakers could enact change by making the environmental unfriendliness of non-eco-friendly products visible to the public and thus increase the potential for GCB. Originality/value The results validate the emerging understanding that green products are consumed for self-enhancement, but also expand the literature by highlighting that a key motivating factor of GCB is the desire to fit in.

It’s Not What You Sell : It’s Whom You Sell it To: How the Customer’s Character Shapes Brands and What Companies Do About it

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- In this dissertation I investigate the effects of user and usage imagery on brands and how businesses employ user imagery to build brands. Over four articles I present results that suggest that user imagery affects brand personality and that companies under certain conditions adapt their behavior to optimize this effect. Although both mass market fashion and nightclubs are susceptible to the influence of user imagery, out of the two only nightclubs actively reject customers to improve its effect on brand perception. I relate these practices to the practical and financial feasibility of rejecting customers, the character of nightclubs’ brands, and to their inability to differentiate their brands through any other brand personality influencer besides user imagery. In this dissertation, I also discuss the ethical ramifications of user imagery optimization through customer rejection. In one study, the role of conspicuous usage imagery on socially desirable consumer behavior is investigated. It is concluded that conspicuousness increases consumers' propensity to choose environmentally friendly products, and that this tendency is especially pronounced for individuals that are high in attention to social comparison information. The conclusion is that consumers use green products to self-enhance for the purpose of fitting in with the group rather than to stand out from it.

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- In the last few decades, the topic of environmental sustainability has received much attention within the marketing literature (Powell, 2011, Leonidou et al., 2013). As our world faces many environmental challenges, both large and small, the thought that part of the solution to these problems is in the consumption based arena has become more popular. To steer toward a more environmentally sustainable consumption is thus seen as desirable for many actors in society. However, while the concepts of green, sustainable, or environmental marketing have existed for several decades, the actual results of these initiatives are discouraging from both research and sustainability perspectives (Crane, 2000). There is a vast " attitude - behavior gap" (Moraes et al., 2 012, Carrington et al., 2010, Carrington et al., 2014) which means that although consumers profess to be positively disposed towards organic products, they do not act accordingly. Traditionally, research in this field has focused on how products’ functiona l benefits and consumers’ values and norms affect green consumer behavior (Salazar et al., 2013) . There is however an emerging understanding that consumers may seek more than functional value from their environmentally friendly brands, value like e.g. stat us (Griskevicius et al., 2010) and identity (Sexton and Sexton, 2011). Thus, for green products to be successful it may not be sufficient to only to be good; they must also make their user seem good. While building on the symbolic/expressive meaning of consumption is a commonly accepted idea within brand building (e.g. Park et al., 1986, Aaker, 1997, Fang et al., 2012) , it has received limited attention within the green consumer behavior domain. We propose that from the symbolic consumption perspective, environmentally friendly products that are consumed conspicuously should represent greater value than those that are consumed inconspicuously. Against this background, the purpose of this paper is to investigate if consumers choose environmentally friendly options to a greater extent if the consumption setting is public rather than private consumption situations.
