  • ReCOV : recovery and rehabilitation during and after COVID-19-a study protocol of a longitudinal observational study on patients, next of kin and health care staff
  • 2021
  • Ingår i: BMC Sports Science, Medicine and Rehabilitation. - : Springer Science and Business Media LLC. - 2052-1847. ; 13:1
  • Tidskriftsartikel (refereegranskat)abstract
    • Background: The knowledge of the long-term consequences of covid-19 is limited. In patients, symptoms such as fatigue, decreased physical, psychological, and cognitive function, and nutritional problems have been reported. How the disease has affected next of kin, as well as staff involved in the care of patients with covid-19, is also largely unknown. The overall aim of this study is therefore three-fold: (1) to describe and evaluate predictors of patient recovery, the type of rehabilitation received and patients’ experiences of specialized rehabilitation following COVID-19 infection; (2) to study how next of kin experienced the hospital care of their relative and their experiences of the psychosocial support they received as well as their psychological wellbeing; (3) to describe experiences of caring for patients with COVID-19 and evaluate psychological wellbeing, coping mechanisms and predictors for development of psychological distress over time in health care staff.Methods: This observational longitudinal study consists of three cohorts; patients, next of kin, and health care staff. The assessments for the patients consist of physical tests (lung function, muscle strength, physical capacity) and questionnaires (communication and swallowing, nutritional status, hearing, activities of daily living, physical activity, fatigue, cognition) longitudinally at 3, 6 and 12 months. Patient records auditing (care, rehabilitation) will be done retrospectively at 12 months. Patients (3, 6 and 12 months), next of kin (6 months) and health care staff (baseline, 3, 6, 9 and 12 months) will receive questionnaires regarding, health-related quality of life, depression, anxiety, sleeping disorders, and post-traumatic stress. Staff will also answer questionnaires about burnout and coping strategies. Interviews will be conducted in all three cohorts.Discussion: This study will be able to answer different research questions from a quantitative and qualitative perspective, by describing and evaluating long-term consequences and their associations with recovery, as well as exploring patients’, next of kins’ and staffs’ views and experiences of the disease and its consequences. This will form a base for a deeper and better understanding of the consequences of the disease from different perspectives as well as helping the society to better prepare for a future pandemic.

  • Simulation of (125) I Auger emission spectrum with new atomic parameters from MCDHF calculations
  • 2022
  • Ingår i: Journal of Quantitative Spectroscopy and Radiative Transfer. - : Elsevier. - 0022-4073 .- 1879-1352. ; 277
  • Tidskriftsartikel (refereegranskat)abstract
    • New 125 I atomic decay emission data of medical interest are presented. The calculations are based on two atomic structure codes that implement the multi-configuration Dirac-Hartree-Fock method. Radiative and non-radiative ransition rates are calculated in this method and then used to generate the atomic deexcitation cascade. Subshell transition rates, level widths and fluorescence yields are compared to the Evaluated Atomic Data Library. Coster-Kronig and Auger electron emission yields are also compared with results from other authors. The comparison with the experimental electron emission spectrum shows that the new calculations can reproduce very well the structure of the K-LL Auger electron peaks and improve the description of the M Auger peaks below 300 eV. The 125 I dose-point kernel is also simulated using the new data, resulting in higher values below 10 nm when compared those obtained with the Evaluated Atomic Data Library.

  • Evolution of overall survival (OS) in patients (pts) with incident NSCLC in Denmark and Sweden : A SCAN-LEAF study analysis from the I-O Optimise initiative
  • 2019
  • Ingår i: Annals of Oncology. - : Elsevier BV. - 0923-7534. ; 30:Suppl 2, s. 16-17
  • Konferensbidrag (refereegranskat)abstract
    • Background: As part of I-O Optimise, a multinational research platform providing real-world insights into the management of lung cancers, the SCAN-LEAF study aims to describe the epidemiology, clinical care, and outcomes for pts with NSCLC in Scandinavia. Here, we report temporal OS trends among pts diagnosed with incident NSCLC from 2005 to 2015 in Denmark and Sweden. Methods: The SCAN-LEAF Danish and Swedish cohorts were established by linking respective national registries and include all adult pts diagnosed with incident NSCLC from Jan 2005 to Dec 2015 (follow-up to Dec 2016). The Kaplan–Meier method was used to estimate OS at 1, 3, and 5 yrs by histology (non-squamous cell [NSQ] or squamous cell [SQ]), TNM stage, and yr of diagnosis; changes in OS over time were assessed using the Cochrane–Armitage test. Results: 31,939 pts in Denmark and 30,067 pts in Sweden were diagnosed with NSCLC from 2005 to 2015. Most were diagnosed at stage IV (51.6% and 48.4%, respectively) and had NSQ histology (54.4% and 60.4%). Statistically significant trends (P < 0.05) for improved OS accompanied by an absolute OS rate increase of > 5% over the analysis period were seen for NSQ pts at 1 yr for all stages in both countries (Table); at 3 yrs for stages I–IIIB in Denmark (P ≤ 0.027), and stages I–II (P ≤ 0.0013) in Sweden; and at 5 yrs for stages I–II (P ≤ 0.026) in both countries. For SQ pts, this was seen only at 1 yr for stage IIIA in Denmark and stage I in Sweden (Table), and at 5 yrs for stage IIIA in Denmark (p = 0.02). Conclusions: Despite some improvements between 2005 and 2015, mainly in the short-term survival of pts with early-stage NSCLC, long-term OS rates for pts with late-stage disease did not change significantly and remained low. Even in pts with early-stage disease, OS outcomes were suboptimal, with a particular unmet need in the SQ population. Future analyses including data after 2015 will evaluate the potential impact on OS of increased use of new TKIs and immune checkpoint inhibitors.

  • Synergistic HNO3–H2SO4–NH3 upper tropospheric particle formation
  • 2022
  • Ingår i: Nature. - : Springer Science and Business Media LLC. - 0028-0836 .- 1476-4687. ; 605:7910, s. 483-489
  • Tidskriftsartikel (refereegranskat)abstract
    • New particle formation in the upper free troposphere is a major global source of cloud condensation nuclei (CCN). However, the precursor vapours that drive the process are not well understood. With experiments performed under upper tropospheric conditions in the CERN CLOUD chamber, we show that nitric acid, sulfuric acid and ammonia form particles synergistically, at rates that are orders of magnitude faster than those from any two of the three components. The importance of this mechanism depends on the availability of ammonia, which was previously thought to be efficiently scavenged by cloud droplets during convection. However, surprisingly high concentrations of ammonia and ammonium nitrate have recently been observed in the upper troposphere over the Asian monsoon region. Once particles have formed, co-condensation of ammonia and abundant nitric acid alone is sufficient to drive rapid growth to CCN sizes with only trace sulfate. Moreover, our measurements show that these CCN are also highly efficient ice nucleating particles—comparable to desert dust. Our model simulations confirm that ammonia is efficiently convected aloft during the Asian monsoon, driving rapid, multi-acid HNO3–H2SO4–NH3 nucleation in the upper troposphere and producing ice nucleating particles that spread across the mid-latitude Northern Hemisphere.
