  • FERMI OBSERVATIONS OF GRB 090902B : A DISTINCT SPECTRAL COMPONENT IN THE PROMPT AND DELAYED EMISSION
  • 2009
  • Ingår i: Astrophysical Journal Letters. - 2041-8205. - 0004-637X ; 706:1, s. L138-L144
  • Tidskriftsartikel (refereegranskat)abstract
    • We report on the observation of the bright, long gamma-ray burst (GRB), GRB 090902B, by the Gamma-ray Burst Monitor (GBM) and Large Area Telescope (LAT) instruments on-board the Fermi observatory. This was one of the brightest GRBs to have been observed by the LAT, which detected several hundred photons during the prompt phase. With a redshift of z = 1.822, this burst is among the most luminous detected by Fermi. Time-resolved spectral analysis reveals a significant power-law component in the LAT data that is distinct from the usual Band model emission that is seen in the sub-MeV energy range. This power-law component appears to extrapolate from the GeV range to the lowest energies and is more intense than the Band component, both below similar to 50 keV and above 100 MeV. The Band component undergoes substantial spectral evolution over the entire course of the burst, while the photon index of the power-law component remains constant for most of the prompt phase, then hardens significantly toward the end. After the prompt phase, power-law emission persists in the LAT data as late as 1 ks post-trigger, with its flux declining as t(-1.5). The LAT detected a photon with the highest energy so far measured from a GRB, 33.4(-3.5)(+ 2.7) GeV. This event arrived 82 s after the GBM trigger and similar to 50 s after the prompt phase emission had ended in the GBM band. We discuss the implications of these results for models of GRB emission and for constraints on models of the extragalactic background light.

  • Evaluation of a Swedish version of the Watts Sexual Function Questionnaire (WSFQ) in persons with heart disease : A pilot study
  • 2010
  • Ingår i: European Journal of Cardiovascular Nursing. - 1474-5151. ; 9:3, s. 168-174
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: As part of preparation for a Swedish multicentre study, exploring sexual and married life in patients with myocardial infarction and their partners, a Swedish validated instrument was required.Aims: The aim of this pilot study was to evaluate the validity and reliability of a Swedish version of the Watts Sexual Function Questionnaire (WSFQ) among persons with a heart disease.Methods: A convenience sample of 79 persons (47 men and 32 women) living with a heart disease was recruited from the members of the National Association of Heart and Lung Patients. They completed a Swedish version of the WSFQ on two occasions.Results: Two separate factor analyses each revealed a two-factor structure on both occasions: “Sexual appetite” and “Sexual expectations” with gender-neutral questions and “Sexual sensitiveness” and “Sexual ability” with gender-specific questions. Cronbach's alpha coefficients ranged from 0.48 to 0.86 and test–retest values for all but one question exceeded 0.70.Conclusions: The Swedish version of the WSFQ showed good validity and stability and acceptable internal homogeneity. Extended evaluations of the questionnaire are recommended.

  • Validity and reliability of a Swedish version of the Relationship Assessment Scale (RAS) : a pilot study
  • 2010
  • Ingår i: Canadian journal of cardiovascular nursing. - Ottawa : Canadian Council of Cardiovascular Nurses. - 0843-6096. ; 20:1, s. 16-21
  • Tidskriftsartikel (refereegranskat)abstract
    • BACKGROUND: There is a need for a short and easily administered scale, in the Swedish language, for assessing partner relationships in the health care of persons with cardiac disease. PURPOSE: To establish the reliability and validity of the Swedish version of the Relationship Assessment Scale (RAS). DESIGN: The present pilot study has a methodological design. FINDINGS: Content validity has been tested for relevance, clarity and readability. The scale was tested for construct validity with explorative factor analysis. The reliability was tested by internal consistency and test-retest analysis. The result showed a two-factor solution, which does not correspond to the original proposed one-factor solution. The factor analyses revealed two quite distinct factors of RAS, labelled "Relationship built on expectations and satisfaction of needs" and "Relationship built on love and devotion". CONCLUSIONS: The scale has satisfactory psychometric properties in terms of content validity, construct validity, homogeneity and stability in a population of persons with cardiac disease. Wider evaluations of the RAS for other populations and settings are recommended.

  • Psychometric evaluation of “The 25-item Sex after MI Knowledge Test” in a Swedish context
  • 2012
  • Ingår i: Scandinavian Journal of Caring Sciences. - 0283-9318. ; 26:1, s. 203-208
  • Tidskriftsartikel (refereegranskat)abstract
    • The patients’ sexual life after a myocardial infarction is important for his/her quality of life. In spite of this, many patients are in doubt regarding their sex life after a myocardial infarction (MI) and the sexual information received, and counselling from health care providers has been seen to be insufficient. The purpose of this study was to evaluate the psychometric properties of ‘The 25-item Sex after MI Knowledge Test’ in a Swedish context. A convenience sample was recruited. The scale was translated into Swedish and completed by 79 former patients from The Heart and Lung Patients’ National Association on two occasions, with an interval of 2 weeks. The scale was tested for face and content validity, internal consistency and test–retest reliability. The result in this study indicates that the instrument has good face and content validity and displayed a moderate internal consistency (alpha 0.61). The instrument showed some level of instability in test–retest reliability with 60% of the items presenting moderate or strong agreement between the test and retest. Further studies that use this instrument in larger and more diverse samples are thus needed.

  • Development and validation of a new tool measuring nurses self-reported professional competence - The nurse professional competence (NPC) Scale
  • 2013
  • Ingår i: Nurse Education Today. - Elsevier. - 0260-6917.
  • Tidskriftsartikel (refereegranskat)abstract
    • Objectives: To develop and validate a new toll intended for measuring self-reported professional competence among both nurse students prior to graduation and among praticing nurses. The new tool is based on formal competence requirements from the Swedish Board of Health and Welfare, which in turn are based on WHO guidelines.Design: A methodological study including construction of a new scale and evaluation of its psychometric propersties.Participants and settings: 1086 newly graduated nurse student from 11 universities/university colleges.Results: The analyses resulted in a scale named the NPC (nurse Professional Competence) Scale, consisting of 88 items and covering 8 factors: "Nursing Care", "Value-based Nursing Care", "Medical/technical care", "Teaching/learning and support", "Documentation and information technology", "Legislation in nursing and safety planning", "Leadership and development of nursing care" and "Education and supervision of staff/students". All factors achieved Cronbach´s alpha values greater than 0.70. A second-order exploratory analysis resulted in two main themes: "Patient-related nursing" and "Nursing care organisation and development". In addition evidence of known-group validity for the NPC Scale was obtained.

  • One-Year Survival of Extremely Preterm Infants After Active Perinatal Care in Sweden
  • 2009
  • Ingår i: JAMA-JOURNAL OF THE AMERICAN MEDICAL ASSOCIATION. - 0098-7484. ; 301:21, s. 2225-2233
  • Tidskriftsartikel (refereegranskat)abstract
    • Context Up-to-date information on infant survival after extremely preterm birth is needed for assessing perinatal care services, clinical guidelines, and parental counseling. Objective To determine the 1-year survival in all infants born before 27 gestational weeks in Sweden during 2004-2007. Design, Setting, and Patients Population-based prospective observational study of extremely preterm infants (707 live-born and 304 stillbirths) born to 887 mothers in 904 deliveries (102 multiple births) in all obstetric and neonatal units in Sweden from April 1, 2004, to March 31, 2007. Main Outcome Measures Infant survival to 365 days and survival without major neonatal morbidity (intraventricular hemorrhage grade andgt; 2, retinopathy of prematurity stage andgt; 2, periventricular leukomalacia, necrotizing enterocolitis, severe bronchopulmonary dysplasia). Associations between perinatal interventions and survival. Results The incidence of extreme prematurity was 3.3 per 1000 infants. Overall perinatal mortality was 45% (from 93% at 22 weeks to 24% at 26 weeks), with 30% stillbirths, including 6.5% intrapartum deaths. Of live-born infants, 91% were admitted to neonatal intensive care and 70% survived to 1 year of age (95% confidence interval [CI], 67%-73%). The Kaplan-Meier survival estimates for 22, 23, 24, 25, and 26 weeks were 9.8% (95% CI, 4%-23%), 53% ( 95% CI, 44%-63%), 67% (95% CI, 59%-75%), 82% (95% CI, 76%-87%), and 85% ( 95% CI, 81%-90%), respectively. Lower risk of infant death was associated with tocolytic treatment (adjusted for gestational age odds ratio [ OR], 0.43; 95% CI, 0.36-0.52), antenatal corticosteroids (OR, 0.44; 95% CI, 0.24-0.81), surfactant treatment within 2 hours after birth ( OR, 0.47; 95% CI, 0.32-0.71), and birth at a level III hospital (OR, 0.49; 95% CI, 0.32-0.75). Among 1-year survivors, 45% had no major neonatal morbidity. Conclusion During 2004 to 2007, 1-year survival of infants born alive at 22 to 26 weeks of gestation in Sweden was 70% and ranged from 9.8% at 22 weeks to 85% at 26 weeks.

  • Measurement of the production cross section of jets in association with a Z boson in pp collisions at root s=7 TeV with the ATLAS detector
  • 2013
  • Ingår i: JOURNAL OF HIGH ENERGY PHYSICS. - SPRINGER. - 1029-8479. ; :7, s. 032
  • Tidskriftsartikel (refereegranskat)abstract
    • Measurements of the production of jets of particles in association with a Z boson in pp collisions at root s = 7 TeV are presented, using data corresponding to an integrated luminosity of 4.6 fb(-1) collected by the ATLAS experiment at the Large Hadron Collider. Inclusive and differential jet cross sections in Z events, with Z decaying into electron or muon pairs, are measured for jets with transverse momentum p(T) > 30 GeV and rapidity vertical bar y vertical bar < 4.4. The results are compared to next-to-leading-order perturbative QCD calculations, and to predictions from different Monte Carlo generators based on leading-order and next-to-leading-order matrix elements supplemented by parton showers.
