  • Thermal diffusion of Mn through GaAs overlayers on (Ga, Mn)As
  • 2011
  • Ingår i: Journal of Physics: Condensed Matter. - 0953-8984. ; 23:8
  • Tidskriftsartikel (refereegranskat)abstract
    • Thermally stimulated diffusion of Mn through thin layers of GaAs has been studied by x-ray photoemission. (Ga, Mn)As samples with 5 at% Mn were capped with 4, 6 and 8 monolayer (ML) GaAs, and Mn diffusing through the GaAs was trapped on the surface by means of amorphous As. It was found that the out-diffusion is completely suppressed for an 8 ML thick GaAs film. The short diffusion length is attributed to an electrostatic barrier formed at the (Ga, Mn)As/GaAs interface.

  • Clinical characteristics of asymptomatic left ventricular diastolic dysfunction and its association with self-rated health and N-terminal B-type natriuretic peptide : : a cross-sectional study
  • 2016
  • Ingår i: Heart Failure Clinics. - Elsevier Inc.. - 2055-5822. ; 3:3, s. 205-211
  • Tidskriftsartikel (refereegranskat)abstract
    • AIMS: Left ventricular hypertrophy, obesity, hypertension, and N-terminal B-type natriuretic peptide (Nt-proBNP) predict left ventricular diastolic dysfunction with preserved systolic function (DD-PSF). Self-rated health (SRH) is shown to be associated with chronic diseases, but the association of SRH with DD-PSF is unclear. In light of the clinical implications of DD-PSF, the following goals are of considerable importance: (1) to determine the role of SRH in patients with DD-PSF in the general population and (2) to study the association between Nt-proBNP and DD-PSF.METHODS AND RESULTS: The current study is a cross-sectional study conducted on a random sampling of a rural population. Individuals 30-75 years of age were consecutively subjected to conventional echocardiography and tissue velocity imaging. Data were collected on 500 (48%) men and 538 (52%) women (n = 1038). DD-PSF was the main outcome, and SRH and Nt-proBNP were the primary indicators. Diabetes mellitus, hypertension, and obesity were accounted for as major confounders of the association with SRH. DD-PSF was identified in 137 individuals, namely, 79 men (15.8%) and 58 women (10.8%). In a multivariate regression model, SRH (OR 2.95; 95% CI 1.02-8.57) and Nt-proBNP (quartile 4 vs. quartile 1 OR 4.23; 95% CI 1.74-10.26) were both independently associated with DD-PSF.CONCLUSIONS: SRH, evaluated based on a descriptive question on general health, should be included in the diagnostic process of DD-PSF. In agreement with previous studies, our study confirms that Nt-proBNP is a major indicator of DD-PSF.

  • Attitudes Regarding Participation in a Diabetes Screening Test among an Assyrian Immigrant Population in Sweden
  • 2016
  • Ingår i: Nursing Research and Practice. - 2090-1429.
  • Tidskriftsartikel (refereegranskat)abstract
    • Immigrants from the Middle East have higher prevalence and incidence of type 2 diabetes (T2D) compared with native Swedes. The aim of the study was to describe and understand health beliefs in relation to T2D as well as attitudes regarding participation in a screening process in a local group of Assyrian immigrants living in Sweden. A qualitative and quantitative method was chosen in which 43 individuals participated in a health check-up and 13 agreed to be interviewed. Interviews were conducted, anthropometric measurements and blood tests were collected, and an oral glucose tolerance test was performed. In total, 13 of the 43 participants were diagnosed with impaired glucose metabolism, 4 of these 13 had TD2. The interviewed participants perceived that screening was an opportunity to discover more about their health and to care for themselves and their families. Nevertheless, they were not necessarily committed to taking action as a consequence of the screening. Instead, they professed that their health was not solely in their own hands and that they felt safe that God would provide for them. Assyrians’ background and religion affect their health beliefs and willingness to participate in screening for TD2.

  • The association between self-rated health and impaired glucose tolerance in Swedish adults: A cross-sectional study
  • 2013
  • Ingår i: Scandinavian Journal of Primary Health Care. - 0281-3432. ; 31:2, s. 111-118
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective. To investigate gender differences in the association between self-rated health (SRH) and impaired glucose tolerance (IGT) in subjects unaware of their glucose tolerance. Design. A cross-sectional population-based study. Setting. The two municipalities of Vara and Skovde in south-western Sweden. Subjects. A total of 2502 participants (1301 women and 1201 men), aged 30-75, were randomly selected from the population. Main outcome measures. IGT was regarded as the outcome measure and SRH as the main risk factor. Results. The prevalence of IGT was significantly higher in women (11.9%) than in men (10.1%), (p = 0.029), as was the prevalence of low SRH (women: 35.4%; men: 22.1%, p = 0.006). Both men and women with low SRH had a poorer risk factor profile than those with high SRH, and a statistically significant crude association between SRH and IGT was found in both men (OR = 2.8, 95% CI 1.8-4.4) and women (OR = 1.5, 95% CI 1.0-2.2, p = 0.033). However, after controlling for several lifestyle factors and biomedical variables, the association was attenuated and remained statistically significant solely in men (OR = 2.3, 95% CI 1.2-4.3). Conclusion. The gender-specific associations found between SRH and IGT suggest that SRH may be a better indicator of IGT in men than in women. Future studies should evaluate the utility of SRH in comparison with objective health measures as a potential aid to health practitioners when deciding whether to screen for IGT and T2DM.

  • Short-term results of a prospective randomized evaluator blinded multicenter study comparing TVT and TVT-Secur.
  • 2011

  • Tidskriftsartikel (refereegranskat)abstract
    • INTRODUCTION AND HYPOTHESIS: The aim of this prospective randomized multicenter study was to compare TVT (tension-free vaginal tape) with TVT-Secur in terms of efficacy and safety. METHODS: We set out to enrol 280 stress incontinent women with a half time interim analysis of short-term cure and a continuous registration of adverse events. Of 133 randomized women, 126 were operated and 123 (TVT n = 62, TVT-Secur n = 61) available for 2 months follow-up. RESULTS: No significant differences were found between groups regarding demographics or grade of incontinence. At 2 months follow-up, subjective cure rate following TVT-Secur was significantly lower than for TVT (72% and 92%, respectively, p = 0.01). Three major complications occurred in the TVT-Secur group: tape erosion into the urethra, a tape inadvertently placed inside the bladder, and an immediate postoperative bleeding from the corona mortis. No major complications occurred in the TVT group. No significant differences were found between groups regarding perioperative bleeding, hospital stay, urge symptoms, or postoperative urinary tract infections. Median time for surgery was 13 and 22 min for TVT-Secur and TVT, respectively (p < 0.0001). CONCLUSIONS: In a prospective randomized controlled study, the TVT-Secur procedure had a significantly lower subjective cure rate than the retropubic TVT procedure. Due to this, in addition to three serious complications in the TVT-Secur group, we decided to stop further enrolment after the interim analysis. We discourage from further use of the TVT-Secur.

  • Modern theory of orbital magnetic moment in solids
  • 2017
  • Ingår i: Journal of Physics and Chemistry of Solids. - Elsevier. - 0022-3697. ; s. 1-22
  • Tidskriftsartikel (refereegranskat)abstract
    • The magnetic moment in a solid is usually associated with the electron spins but there is an additional contribution due to the orbital motion of the electrons. For a finite system such as an atom or molecule the orbital moment can be readily calculated. However, for a periodic system the formula used for finite systems becomes ill-defined due to the presence of the position operator. In the last decade a modern theory of orbital magnetization that allows for a rigorous calculation of the magnetic moment of periodic crystals has been developed. This article provides a survey of the theoretical development of this new topic as well as recent, albeit a few, applications of the new formula to real materials. Although the original theory was worked out for non-interacting systems, there has been recent progress in the theory of orbital magnetic moment of interacting electrons in solids. To include the effects of electron-electron interactions two approaches have been proposed, one based on current spin density functional theory and another on the many-body Green's function method. The two approaches are very different but both methods provide convenient yet rigorous means of including the effects of exchange and correlations beyond the commonly used local density approximation of density functional theory.

  • Refill Adherence in Relation to Substitution and the Use of Multiple Medications: A Nationwide Population Based Study on New ACE-Inhibitor Users
  • 2016
  • Ingår i: Plos One. - 1932-6203. ; 11:5
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: Generic substitution has contributed to economic savings but switching products may affect patient adherence, particularly among those using multiple medications. The aim was to analyse if use of multiple medications influenced the association between switching products and refill adherence to angiotensin-converting-enzyme (ACE) inhibitors in Sweden. Study Design and Setting: New users of ACE-inhibitors, starting between 1 July 2006 and 30 June 2007, were identified in the Swedish Prescribed Drug Register. Refill adherence was assessed using the continuous measure of medication acquisition (CMA) and analysed with linear regression and analysis of covariance. Results: The study population included 42735 individuals whereof 51.2% were exposed to switching ACE-inhibitor and 39.6% used multiple medications. Refill adherence was higher among those exposed to switching products than those not, but did not vary depending on the use of multiple medications or among those not. Refill adherence varied with age, educational level, household income, country of birth, previous hospitalisation and previous cardiovascular diagnosis. Conclusion: The results indicate a positive association between refill adherence and switching products, mainly due to generic substitution, among new users of ACE-inhibitors in Sweden. This association was independent of use of multiple medications.

  • Sociodemographic patterns in pharmacy dispensing of medications for erectile dysfunction in Sweden
  • 2018
  • Ingår i: European Journal of Clinical Pharmacology. - Springer. - 1432-1041. ; 74:2, s. 209-218
  • Tidskriftsartikel (refereegranskat)abstract
    • PURPOSE: The purpose of this study is to investigate the relationship between sociodemographic factors and pharmacy dispensing of medications for erectile dysfunction (ED) in the general population of middle-aged and elderly men. By considering a number of medical conditions that could promote or contraindicate use of ED medication, the analysis could help capture prescription patterns that might not be explained by medical needs.METHODS: Individual-level pharmacy dispensing data from 2006 for a population-based cohort of 216,148 men aged 45-79 years in the county Scania, Sweden, were analysed. Multiple logistic regression was applied, and area under the receiver operating characteristic curve (AUC) was calculated to quantify the discriminatory accuracy (DA) of the associations. National trends in pharmacy dispensing of ED medication between 2006 and 2016 were also analysed.RESULTS: Pharmacy dispensing of ED medication increased between 2006 and 2016, particularly among men aged 65-79 years (from 6.8 to 9.2%). Dispensing of ED medication was positively associated with higher socioeconomic position, and divorced and widowed men were more likely to fill a prescription with ED medication than married men. These associations remained after adjusting for medical conditions. The DA of the associations was, however, rather low (AUC = 0.69 among 45-64 year olds and AUC = 0.65 among 65-79 year olds).CONCLUSIONS: Pharmacy dispensing of ED medication seem linked to the individuals socioeconomic position, age and marital status suggesting sociodemographic disparities in the pharmacy dispensing targeting sexual function. However, the low DA of the associations shows the limited capacity of these factors to predict ED medication use at the individual level.
