- We report the first measurement of the magnetic dipole and electric quadrupole moment of the exotic nucleus Sn-133 by high-resolution laser spectroscopy at ISOLDE/CERN. These, in combination with state-of-the-art shell-model calculations, demonstrate the single-particle character of the ground state of this short-lived isotope and, hence, the doubly-magic character of its immediate neighbor Sn-132. The trend of the electromagnetic moments along the N = 83 isotonic chain, now enriched with the values of tin, are discussed on the basis of realistic shell-model calculations.

- Hyperfine structure (HFS) measurements of neutron-rich iridium isotopes Ir-196,Ir-197,Ir-198 (Z = 77, N = 119-121) were performed via in-gas-cell laser resonance ionization spectroscopy at the KEK Isotope Separation System. Magnetic dipole moments mu and isotope shifts were determined from the HFS spectra. The variation of mean-square charge radii and quadrupole deformation parameters of these isotopes were evaluated from the isotope shifts. The mu value of (197)h, agreed with a theoretical value based on the strong coupling model, and the Ir nucleus was interpreted as prolately deformed by the theoretical calculations. The mu values of Ir-196,Ir-198 were also compared with semiempirical values calculated based on the strong coupling model. From the comparison, we can suggest the possible spin values of I-pi = 1,2(-) for Ir-196 and I-pi = 1(-) for Ir-198.

Tidskriftsartikel (refereegranskat)abstract
- There is lack of data addressing the intracranial (IC) efficacy of immune checkpoint inhibitors (ICIs) on brain metastases (BM) in non-small cell lung cancer (NSCLC). This patient category is underrepresented in randomized clinical trials. We retrospectively collected clinical data on patients with non-oncogenic driven NSCLC with BM who were treated with ICIs at two medical oncology institutes in Sweden and Greece from 2016 to 2019. IC efficacy was assessed in patients who had not received local treatment for BM less than three months prior to the initiation of ICIs and had adequate radiological evaluation. We screened 280 patients, of which 51 had BM. BM was an independent predictor for inferior PFS (HR = 2.27; 95% CI, 1.53–3.36) but not OS (HR = 1.58; 95% CI, 0.97–2.60) for the whole patient population. IC response assessment was done on 33 patients. IC objective response rate (ORR) was 24.2%. The presence of neurological symptoms related to BM did not affect IC ORR (p = 0.48). High PD-L1 levels from extracranial biopsies were not a predictive factor for IC ORR (p = 0.13). ICIs are active in NSCLC patients with BM regardless of the presence of neurological symptoms and can achieve durable IC disease stabilization in a subgroup of patients.

ALK-Brain Prognostic Index-Preliminary Study of a Prognostic Tool for Patients with ALK-Rearranged, Non-small Cell Lung Cancer and Brain Metastases

- Background: Disease-specific Graded Prognostic Assessment (DS-GPA) is the most validated prognostic tool for patients with brain metastasized lung cancer. The Lung-molGPA scoring system was recently introduced for oncogenic-driven brain metastasized lung cancer, but has not yet been validated in cohorts including only ALK-translocated tumors. Methods: We designed a retrospective cohort study consisting of 44 patients with brain metastasized ALK-positive, non-small cell lung cancer (NSCLC) who were treated between January 2009 and November 2019 at Karolinska University Hospital in Stockholm, Sweden. Information about demographics and clinicopathological parameters were collected. Predictors of overall survival (OS) were identified by Cox regression analyses. A bootstrap validation with 1000 samples was performed in order to compare the different prognostic scores. Results: The variables found to independently influence OS in the multivariate analysis, i.e., PS, sex and brain metastases at diagnosis, were used as prognostic variables in our new prognostic index (ALK-BPI). Patients were divided into two prognostic groups. The median OS was 65.7 months for the good prognostic group and 22.7 months for the poor prognostic group (p = 0.0068). In the univariate analysis of the different prognostic scores, ALK-BPI performed better than the others (HR = 3.6; 95% CI: 1.3–9.9). The mean C-statistics of the different prognostic scores were compared to each other, and no significant difference was observed. Conclusion: We propose the ALK-BPI score as a new prognostic tool that can easily be applied for ALK-positive lung cancer patients with brain metastases in daily clinical practice, as it has at least the same prognostic value as Lung-molGPA.

- Glucocorticoids (GCs) are a cornerstone in treating various common and uncommon diseases. The aim of this study was to estimate the prevalence of GC use in terms of doses associated with risk of tertiary adrenal insufficiency in adults and children, and treatment indications.This was a retrospective cohort study. Information on dispensed prescriptions was obtained from the Swedish Prescribed Drug Register. Patients with prescriptions of prednisolone (or equivalent dose of other GCs) ≥5 mg daily for ≥21 days between 2007-2014 were included. Information on concurrent diseases was obtained from the Swedish National Patient Register and the Västra Götaland Regional Healthcare Database.Of 1,585,335 inhabitants in Västra Götaland County, 223,211 were included in the study (women 55.6%). Mean age was 48 ± 24 years. Period prevalence of oral GC use during the 8-year study period was 14.1%. The highest prevalence (27.4%) was in men aged 80-89 years and lowest (7.5%) in men 10-19 years of age. The period prevalence in children 0-9 years of age was 10.6%. COPD and asthma were the most common indications for treatment (17.2%) followed by allergy (12.5%), and malignant neoplasms (11.5%). Allergy was the most frequent indication (20.5%) in children and adolescents.Between 2007-2014, every seventh inhabitant in western Sweden received a GC prescription at doses associated with risk of developing tertiary adrenal insufficiency. These findings illustrate the importance of awareness of the potential development of tertiary adrenal insufficiency in both pediatric and adult patients.

Swedish Clean Air and Climate Research Programme – SCAC Final report second phase
- 2020
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The SCAC-2 program was initiated to provide an extended scientific knowledge base in national and international discussions and negotiations on the development of new air pollution policies and measures. Specifically, the program was focused on four main areas where additional knowledge was needed to support further actions: air pollution and climate interactions and hemispheric transport; air pollution and human health with focus on particles from transport and domestic wood burning; ecosystem effects (and air pollution – climate interactions) of ozone and nitrogen, the latter with emphasis on national nitrogen budgets and biodiversity. Finally, integrated assessment modelling and identification of the most efficient abatement strategies was included.

Costing analysis of a digital first-line treatment platform for patients with knee and hip osteoarthritis in Sweden

Tidskriftsartikel (refereegranskat)abstract
- Osteoarthritis (OA) constitutes a major and increasing burden on patients, health care systems and the broader society. It is estimated that around a quarter of the adult population is affected by OA in the knee and hip and that the prevalence of OA will increase over the coming decades largely due to aging and adverse life-style factors. Prevention and effective care are critical to manage the challenges posed by OA. Digital technologies offer opportunities to deliver cost-effective care for chronic diseases, including for OA. We report the results of a costing analysis of a new digital platform for delivering first-line care including disease information and physiotherapy to patients with OA and compare this with an existing face-to-face model of treatment. Both models are in accordance with National Treatment Guidelines in Sweden. The results show that overall the digital model costs around 25% of the existing face-to-face model of care. Based on existing evidence on the effects of these models, our findings also suggest that the digital platform offers a cost-effective alternative to the existing model of OA care. Depending on the extent to which the digital model substitutes for the existing model of care, significant resources can be saved.
