- A Soft X-ray Laser (SXL) beamline utilising FEL technology is being designed for the Short Pulse Facility (SPF) at the MAX IV Laboratory. A conceptual design study has been started following on the scientific case already prepared in collaboration between several Swedish Universities and driven by a strong (Swedish) user demand. The baseline goal of the SXL beamline is to generate intense and short pulses in the range 1-5 nm (0.2-1 keV). The system is building on the MAX IV linac system, already today providing 100 fs 3 GeV and pulses compressed to 100 fs for other applications within the SPF. As a special feature we foresee a variety of pump-probe capabilities.

Two phase-matching regimes in high-order harmonic generation
- 2023

Ingår i: Optics Express. - 1094-4087. ; 31:20, s. 31687-31697

Tidskriftsartikel (refereegranskat)abstract
- High-order harmonic generation (HHG) provides scalable sources of coherent extreme ultraviolet radiation with pulse duration down to the attosecond time scale. Efficient HHG requires the constructive interplay between microscopic and macroscopic effects in the generation volume, which can be achieved over a large range of experimental parameters from the driving field properties to those of the generating medium. Here, we present a systematic study of the harmonic yield as a function of gas pressure and medium length. Two regimes for optimum yield are identified, supporting the predictions of a recently proposed analytical model. Our observations are independent on the focusing geometry and, to a large extent, on the pulse duration and laser intensity, providing a versatile approach to HHG optimization.

Endoscopic carpal tunnel release: prospective assessment of 255 consecutive cases
- 1997
-
Ingår i: Journal of Hand Surgery: European Volume. - 2043-6289. ; 22:1, s. 42-47
-
Tidskriftsartikel (refereegranskat)abstract
- A prospective study was conducted to evaluate the efficacy and safety of two-portal endoscopic carpal tunnel release. Two hundred and fifty-five consecutive hands (204 patients) were operated on by one surgeon using general or regional anaesthesia in the first 48 hands and local anaesthesia in the following 207 hands. The patients were evaluated preoperatively and 3 and 6 months postoperatively by an independent examiner. At the 6-month follow-up, 83% reported complete relief of symptoms and 89% were satisfied with the results of surgery. The median time until return to work was 17 days. Complications included five postoperative digital neurapraxias, all occurring under general or regional anaesthesia, and four open reoperations due to persistent symptoms. Two-portal endoscopic carpal tunnel release can be effective and safe and appears to shorten the time until return to work. The use of local anaesthesia might be important in avoiding neurological complications.

Quality of life after hip revision with impaction bone grafting on a par with that 4 years after primary cemented arthroplasty
- 2004

Tidskriftsartikel (refereegranskat)abstract
- Background There have been few studies evaluating patient-reported quality of life outcomes after hip revision with impaction bone grafting. Patients and methods The inclusion criteria were aseptic loosening after primary arthroplasty performed for osteoarthrosis, and first-time revision with impacted morselized allograft bone and cemented Exeter stem. During a 4-year period, 35 patients were eligible and all were included. The Nottingham Health Profile (NHP) was completed by the patients and the Charnley hip scores recorded by the examining surgeon preoperatively, after 6 months and yearly up to 4 years (28 patients) postoperatively. For comparison, 35 osteoarthrotic patients completed the NHP 4 years after cemented Exeter primary arthroplasty. Results At 4 years, the NHP scores for the revision patients did not differ significantly from those recorded in the primary arthroplasty group. Among the revision patients, mixed model analysis showed improvement in NHP pain (p < 0.001) and physical mobility scores (p = 0.002). The effect size at 4 years was large for pain (1.2) and moderate for physical mobility (0.6). The major improvement was recorded at 6 months, with no further substantial change observed. The correlations between the NHP and Charnley scores were weak or moderate (r, -0.15 to -0.67). Interpretation Hip revision with impaction bone grafting leads to substantially improved quality of life, similar to that 4 years after primary arthroplasty.

Development, evaluation and implementation of a digital behavioural health treatment for chronic pain : study protocol of the multiphase DAHLIA project
- 2022

Tidskriftsartikel (refereegranskat)abstract
- INTRODUCTION: Chronic pain affects about 20%-40% of the population and is linked to mental health outcomes and impaired daily functioning. Pharmacological interventions are commonly insufficient for producing relief and recovery of functioning. Behavioural health treatment is key to generate lasting benefits across outcome domains. However, most people with chronic pain cannot easily access evidence-based behavioural interventions. The overall aim of the DAHLIA project is to develop, evaluate and implement a widely accessible digital behavioural health treatment to improve well-being in individuals with chronic pain.METHODS AND ANALYSIS: The project follows the four phases of the mHealth Agile Development and Evaluation Lifecycle: (1) development and pre-implementation surveillance using focus groups, stakeholder interviews and a business model; (2) iterative optimisation studies applying single case experimental design (SCED) method in 4-6 iterations with n=10 patients and their healthcare professionals per iteration; (3) a two-armed clinical randomised controlled trial enhanced with SCED (n=180 patients per arm) and (4) interview-based post-market surveillance. Data analyses include multilevel modelling, cost-utility and indicative analyses.In October 2021, inter-sectorial partners are engaged and funding is secured for four years. The treatment content is compiled and the first treatment prototype is in preparation. Clinical sites in three Swedish regions are informed and recruitment for phase 1 will start in autumn 2021. To facilitate long-term impact and accessibility, the treatment will be integrated into a Swedish health platform (www.1177.se), which is used on a national level as a hub for advice, information, guidance and e-services for health and healthcare.ETHICS AND DISSEMINATION: The study plan has been reviewed and approved by Swedish ethical review authorities. Findings will be actively disseminated through peer-reviewed journals, conference presentations, social media and outreach activities for the wider public.TRIAL REGISTRATION NUMBER: NCT05066087.
