  • 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.

  • 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
  • Ingår i: International Urogynecology Journal. - Springer. - 1433-3023. ; 22, s. 781-787
  • 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.

  • An everyday struggle- Swedish families' lived experiences during a child's cancer treatment
  • 2008
  • Ingår i: Journal of Pediatric Nursing: Nursing Care of Children and Families. - Elsevier. - 1532-8449. ; 24:5, s. 423-432
  • Tidskriftsartikel (refereegranskat)abstract
    • The aim was to elucidate families' lived experience during a child's cancer treatment. Interviews were conducted with members of 11 affected families. A hermeneutical phenomenological approach was chosen. "Focus on the ill child-An everyday struggle" emerged as an essential theme. The families' lived experience of daily life was described as "feeling drained," "disrupting family life," "feeling locked up and isolated," "retaining normality," "becoming experts," and "changing perspectives." The result indicates that life during a child's cancer treatment is a taxing period and that the entire family is in need of support to ease their burdens.

  • Like being covered in a wet and dark blanket – Parents' lived experiences of losing a child to cancer
  • 2016
  • Ingår i: European Journal of Oncology Nursing. - Elsevier. - 1462-3889. ; 25, s. 40-45
  • Tidskriftsartikel (refereegranskat)abstract
    • Purpose The aim of this study was to illuminate parents' lived experiences of losing a child to cancer. Method Interviews and a narrative about parents' experiences of losing a child to cancer were gathered from six parents of children whom had participated in a longitudinal study across the child's illness trajectory. The analysis of the data was inspired by van Manen's hermeneutic phenomenological approach. Results One essential theme emerged: Like being covered in a wet and dark blanket, as well as six related themes: Feeling conflicting emotions, Preparing for the moment of death, Continuing parenting after death, Recollecting and sharing memories, Working through the sorrow and New perspectives in life. Conclusion There is a need for good palliative care. If not, there is a risk that the parent will perseverate and blame themselves for not being a good parent during the suffering child's last time in life. Meetings with the parents six months and two years after the child's death might facilitate healing through the grief process.

  • Needs of young children with cancer during their initial hospitalization: an observational study.
  • 2006
  • Ingår i: Journal of Pediatric Oncology Nursing. - SAGE Publications. - 1043-4542. ; 23:4, s. 9-210
  • Tidskriftsartikel (refereegranskat)abstract
    • The aim of this study was to describe young (under the age of 7) children’s needs as expressed by their behavior, body language and verbal expression through observations during their initial hospitalization after being diagnosed with cancer. Twelve children under the age of seven were followed during 26 hours with nonparticipant unstructured observations. Field notes were written after each observation and transcribed into a narrative text, which was analyzed by content analysis at both manifest and latent level. Five themes were identified, of which “need to have the parent close by” was the most prominent. The other themes were “need to play and feel joy,” “need for participation in care and treatment,” “need for a good relationship with the staff,” and “need for physical and emotional satisfaction.” The results indicate that the children needed their parents and the parents’presence helped the children to express other needs. Professionals need to support the child and his or her parents so that the parents in their turn can support and alleviate their child’s hospitalization and cancer treatment.

  • Returning to a changed ordinary life - families' lived experience after completing a child's cancer treatment
  • 2011
  • Ingår i: European Journal of Cancer Care. - John Wiley & Sons. - 1365-2354. ; 20:2, s. 163-169
  • Tidskriftsartikel (refereegranskat)abstract
    • The aim of the study was to illuminate the families' lived experience after completing a child's cancer treatment. The study took place at a University Hospital in southern Sweden. Interviews were carried out with 10 mothers, eight fathers, four patients and two siblings from a total of 10 families. The interviews were analysed with a hermeneutical phenomenological approach. One essential theme emerged from their stories, 'returning to a changed ordinary life - incorporating a trying and contradictory experience'. The families felt relieved that the treatment was over yet they experienced strains in their daily life. Family members felt changed and especially the parents needed to focus on themselves in order to recover. Closeness with other people, especially their own family, was important. The previously sick children felt a loss of concern from their parents when treatment had ended, in contrast to siblings who experienced increased attention from their parents. Parents experienced being in uncharted territory and sometimes missed the security of hospital. For professionals it is important to offer the family a structured follow-up to help them in their daily life after the child's treatment is completed.

  • Striving to survive: families' lived experiences when a child is diagnosed with cancer.
  • 2005
  • Ingår i: Journal of Pediatric Oncology Nursing. - SAGE Publications. - 1043-4542. ; 22:5, s. 75-265
  • Tidskriftsartikel (refereegranskat)abstract
    • When a child is ill with cancer, this affects the whole family for long periods. The aim of this study was to elucidate the family's lived experience when a child in the family was diagnosed with cancer. A descriptive inductive design with a hermeneutic phenomenological approach including interviews with 17 families (parents, children, and siblings) was chosen. The families' lived experience was described as a 2-fold essential theme comprising "a broken life world" and an immediate "striving to survive." The families' secure everyday life disappeared and was replaced by fear, chaos, and loneliness. When striving to make the child and the family survive, family members strove to feel hope and have a positive focus, to gain control, and to feel close to other people. Phenomenological human science research can deepen the understanding of the meaning of being a family with a child who is ill with cancer and can help pediatric oncology staff become increasingly thoughtful, and thus better prepared to take action to diminish the chaos occurring in the family. © 2005 by Association of Pediatric Oncology Nurses.
