Search for elements 119 and 120
- 2020
-
Ingår i: Physical Review C. - 2469-9985. ; 102:6
-
Tidskriftsartikel (refereegranskat)abstract
- A search for production of the superheavy elements with atomic numbers 119 and 120 was performed in the 50Ti+249Bk and 50Ti+249Cf fusion-evaporation reactions, respectively, at the gas-filled recoil separator TASCA at GSI Darmstadt, Germany. Over four months of irradiation, the 249Bk target partially decayed into 249Cf, which allowed for a simultaneous search for both elements. Neither was detected at cross-section sensitivity levels of 65 and 200 fb for the 50Ti+249Bk and 50Ti+249Cf reactions, respectively, at a midtarget beam energy of Elab = 281.5 MeV. The nonobservation of elements 119 and 120 is discussed within the concept of fusion-evaporation reactions including various theoretical predictions on the fission-barrier heights of superheavy nuclei in the region of the island of stability.

On the adsorption and reactivity of element 114, flerovium
- 2022

Ingår i: Frontiers in Chemistry. - : Frontiers Media SA. - 2296-2646. ; 10

Tidskriftsartikel (refereegranskat)abstract
- Flerovium (Fl, element 114) is the heaviest element chemically studied so far. To date, its interaction with gold was investigated in two gas-solid chromatography experiments, which reported two different types of interaction, however, each based on the level of a few registered atoms only. Whereas noble-gas-like properties were suggested from the first experiment, the second one pointed at a volatile-metal-like character. Here, we present further experimental data on adsorption studies of Fl on silicon oxide and gold surfaces, accounting for the inhomogeneous nature of the surface, as it was used in the experiment and analyzed as part of the reported studies. We confirm that Fl is highly volatile and the least reactive member of group 14. Our experimental observations suggest that Fl exhibits lower reactivity towards Au than the volatile metal Hg, but higher reactivity than the noble gas Rn.

Distinct germline genetic susceptibility profiles identified for common non-Hodgkin lymphoma subtypes
- 2022

Ingår i: Leukemia. - : Springer Nature. - 0887-6924 .- 1476-5551. ; 36:12, s. 2835-2844

Tidskriftsartikel (refereegranskat)abstract
- Lymphoma risk is elevated for relatives with common non-Hodgkin lymphoma (NHL) subtypes, suggesting shared genetic susceptibility across subtypes. To evaluate the extent of mutual heritability among NHL subtypes and discover novel loci shared among subtypes, we analyzed data from eight genome-wide association studies within the InterLymph Consortium, including 10,629 cases and 9505 controls. We utilized Association analysis based on SubSETs (ASSET) to discover loci for subsets of NHL subtypes and evaluated shared heritability across the genome using Genome-wide Complex Trait Analysis (GCTA) and polygenic risk scores. We discovered 17 genome-wide significant loci (P < 5 × 10−8) for subsets of NHL subtypes, including a novel locus at 10q23.33 (HHEX) (P = 3.27 × 10−9). Most subset associations were driven primarily by only one subtype. Genome-wide genetic correlations between pairs of subtypes varied broadly from 0.20 to 0.86, suggesting substantial heterogeneity in the extent of shared heritability among subtypes. Polygenic risk score analyses of established loci for different lymphoid malignancies identified strong associations with some NHL subtypes (P < 5 × 10−8), but weak or null associations with others. Although our analyses suggest partially shared heritability and biological pathways, they reveal substantial heterogeneity among NHL subtypes with each having its own distinct germline genetic architecture.

- Digital anamorphosis is used to define a distorted image of health and care that may be viewed correctly using digital tools and strategies. MASK digital anamorphosis represents the process used by MASK to develop the digital transformation of health and care in rhinitis. It strengthens the ARIA change management strategy in the prevention and management of airway disease. The MASK strategy is based on validated digital tools. Using the MASK digital tool and the CARAT online enhanced clinical framework, solutions for practical steps of digital enhancement of care are proposed.

ACURATE neo2 Transcatheter aortic valve implantation without balloon aortic valvuloplasty : direct ACURATE neo2
- 2024
-
Ingår i: International Journal of Cardiology. - 0167-5273 .- 1874-1754. ; 400
-
Tidskriftsartikel (refereegranskat)abstract
- Background: ACURATE neo2 (Neo2) implantation is performed after systematic Balloon Aortic Valvuloplasty (BAV) in most patients. No reports exist about the feasibility and safety of direct Neo2 transcatheter aortic valve implantation (TAVI) in comparison to the standard practice. Aim: We aimed to identify the patients' baseline anatomical characteristics, procedural, and early post-procedural outcomes in patients treated using Neo2 with and without BAV. Methodology: This is a retrospective multicentre analysis of 499 patients with severe aortic stenosis who underwent TAVI using Neo2. The comparison was done according to the performance or omission of BAV. Echocardiography and computed tomography were analysed by an independent Core Lab. Propensity score matching (PSM) was performed based on the annular diameter and AV calcium volume, which identified 84 matched pairs. Results: Among the cohort included, 391 (78%) patients received BAV (BAV-yes) and 108 (22%) were not attempted (BAV-no or Direct TAVI). Patients in BAV-no cohort had smaller annular diameter (22.6 vs 23.4 mm; p < 0.001) and lower calcium volume (163 vs 581 mm3; p < 0.001) compared to BAV-yes cohort. In the matched cohort, VARC-3 device technical success was similar (95%) and all other outcome measures were statistically comparable between cohorts. Conclusion: Direct TAVI using ACURATEneo2 without pre-TAVI balloon aortic valvuloplasty in patients with mild or less valve calcifications might be feasible and associated with comparable early outcomes compared to patients with similar anatomical features undergoing systematic balloon valvuloplasty.

Childhoods and Time: A Collective Exploration
- 2023
-
Ingår i: Journal of Childhood Studies. - 2371-4107. ; 48:1, s. 133-147
-
Tidskriftsartikel (refereegranskat)abstract
- This collective piece explores the philosophical, ontological, and epistemic potentials of analyzing the relations between childhood and time, proposing thought experiments and fieldwork analyses that release childhood from a linear temporality toward (modern) adulthood. Each experiment originating from the authors' distinct scholarly positionings fractures "modern childhood " and its civilization project, built from the hegemony of linear, sequential, progressive, and principled time.

Perioperative fasting times in children and adolescents
- 2022
-
Ingår i: Anasthesiologie und Intensivmedizin. - : AKTIV DRUCK & VERLAG GMBH. - 0170-5334 .- 1439-0256. ; 63, s. 320-328

Tidskriftsartikel (refereegranskat)abstract
- The German Scientific Working Group for Paediatric Anaesthesia (Wissenschaftlicher Arbeitskreis Kinderansthesie, WAKKA) of the German Society for Anaesthesia and Intensive Care Medicine (DGAI) has updated their current recommendations on preoperative fasting in children from 2007, along with the preoperative fasting statement of the German Association of Anaesthesiologists (Berufsverband Deutscher Anasthesisten, BDA) and DGAI from 2016 in agreement with the new evidence-based European Guideline of the European Society of Anaesthesiology and Intensive Care (ESAIC) of 2022 - and transferred it into the S1 Guideline format of the Association of the Scientific. Medical Societies in Germany (Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgeselischaften e. V., AWMF). This revision became necessary because recent studies had shown that optimized fasting times improved hornoeostasis and well-being of the children, while the risk of regurgitation and aspiration had not increased. On the other hand, long periods of fasting might be the cause of misbehaviour, stress, iatrogenic dehydration and catabolism. The updated S1 Guideline therefore recommends shorter fasting times of 4 hours for small, light meals and/or formula or cow's milk (still 6 hours for a full meal), 3 hours for breast milk, and 1 hour for clear fluids (6-4-3-1 Rule). In addition, the new S1 Guideline contains further recommendations for children with concomitant diseases that are of relevance to anaesthesia, for the application of ultrasound to examine the stomach content prior to the induction of anaesthesia, for postoperative fasting and the implementation of the new rules in clinical practice.
