- Objective: To evaluate a structured physiotherapy treatment model in patients who qualify for lumbar disc surgery. Design: A prospective cohort study. Patients: Forty-one patients with lumbar disc herniation, diagnosed by clinical assessments and magnetic resonance imaging. Methods: Patients followed a structured physiotherapy treatment model, including Mechanical Diagnosis and Therapy (MDT), together with graded trunk stabilization training. Study outcome measures were the Oswestry Disability Index, a visual analogue scale for leg and back pain, the Tampa Scale for Kinesiophobia, the European Quality of Life in 5 Dimensions Questionnaires, the Zung Self-Rating Depression Scale, the Self-Efficacy Scale, work status, and patient satisfaction with treatment. Questionnaires were distributed before treatment and at 3-, 12- and 24-month follow-ups. Results: The patients had already improved significantly (p<0.001) 3 months after the structured physiotherapy treatment model in all assessments: disability, leg and back pain, kinesiophobia, health-related quality of life, depression and self-efficacy. The improvement could still be seen at the 2-year follow-up. Conclusion: This study recommends adopting the structured physiotherapy treatment model before considering surgery for patients with symptoms such as pain and disability due to lumbar disc herniation.

- Background and purpose Several studies have investigated outcomes after disc surgery. However, the occurrence of kinesiophobia has not been investigated previously in patients after disc herniation surgery. In this cross-sectional study, we investigated kinesiophobia in patients who had been treated surgically for lumbar disc herniation, and we related the results to established outcome measures. Patients and methods 10?34 months after surgery, questionnaires were sent to 97 patients who had undergone standardized open discectomy. Outcome measures included Tampa scale for kinesiophobia (TSK); Oswestry disability index (ODI); European quality of life in 5 dimensions (EQ-5D); visual analog scale (VAS) for leg and back pain, work disability, and patient satisfaction; Zung self-rating depression scale (ZDS); pain catastrophizing scale (PCS); and a self-efficacy scale (SES). Results 36 of 80 patients reported having kinesiophobia. There were statistically significant differences in ODI, EQ-5D, VAS leg and back pain, ZDS, PCS, and SES between patients with and without kinesiophobia. Interpretation Half of the patients suffered from kinesiophobia 10?34 months after surgery for disc herniation. These patients were more disabled, had more pain, more catastrophizing thoughts, more symptoms of depression, lower self-efficacy, and poorer health-related quality of life than patients without kinesiophobia.

- Objective: To describe the experience of health among patients 3 years after treatment with a structured physiotherapy model or surgery for lumbar disc herniation. Design: A qualitative research study. Subjects/patients: Patients were referred to the orthopaedic clinic at Sahlgrenska University Hospital with sciatica due to lumbar disc herniation. Twenty patients who were eligible for surgery were treated either with a structured physiotherapy model or with surgery. Methods: Open-ended interviews were conducted and analysed using content analysis. Results: Findings were grouped into two themes: feeling of well-being and feeling of ill-being. In the group treated with structured physiotherapy there were a high number of codes in the feeling of well-being theme. In the group treated with surgery there were a high number of codes in the feeling of ill-being theme. Conclusion: Patients treated with structured physiotherapy or surgery experienced feelings of well-being and ill-being 3 years after treatment. Patients treated with physiotherapy and surgery described varying experiences of health 3 years after treatment for lumbar disc herniation. It can be speculated that the experience of well-being may be explained by the ability of structured physiotherapy treatments to empower patients.

Boundary Layer Parametrization in Numerical Weather Prediction Models
- 2015
-
Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Numerical weather prediction (NWP) and climate models have shown to have a challenge to correctly simulate stable boundary layers and diurnal cycles. This aim of this study is to evaluate, describe and give suggestions for improvements of the descriptions of stable boundary layers in operational NWP models. Two papers are included. Paper I focuses on the description of the surface and the interactions between the surface and the boundary layer in COAMPSR, a regional NWP model. The soil parametrization showed to be of great importance to the structure of the boundary layer. Moreover, it showed also that a low frequency of radiation calculations caused a bias in received solar energy at the surface.In paper II, the focus is on the formulation of the turbulent transport in stable boundary layers. There, an implementation of a diffusion parametrization based on the amount of turbulent kinetic energy (TKE) is tested in a single column model (SCM) version of the global NWP model Integrated Forecast System (IFS). The TKE parametrization turned out to behave similarly as the currently operational diffusion parametrization in convective regimes and neutral regimes, but showed to be less diffusive in weakly stable and stable conditions. The formulations of diffusion also turned out to be very dependent on the length scale formulation. If the turbulence and the gradients of wind temperature and wind are weak, the magnitude of turbulence can enter an oscillating mode. This oscillation can be avoided with the use of a lower limit of the length scale.

Evaluation of a TKE diffusion parametrization in IFS Single Column Model
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- An implementation of a diffusion parametrization based on Turbulent KineticEnergy (TKE) in a single column model of the weather forecast model Integrated Forecast System (IFS) is evaluated. Simulations are performed for four test cases GABLS1,GABLS3, DICE and GABLS4. The test cases have different idealization and gives together a comprehensive framework for evaluating the performance for a NWP in representing stably stratified atmospheric boundary layers, diurnal cycles and transition between stable andunstable stratification. The sensitivity to the mixing length scale is evaluated by simulations with alternative formulations and by diagnostic evaluation. An estimation of ageostrophicmass flux is made for idealized test cases.The TKE parametrization is less diffusive than the currently used operational parametrization and shows more realistic stable boundary layers. The magnitude of the diffusivity shows to be very sensitive to length scale formulation. The more diffusive formulations yield weaker gradients of temperature and wind at the surface and smaller angle between surface stress and geostrophic wind. The lower limit of the length scale showed to be ofimportance to avoid unrealistic vertical gradients of wind and temperature close to the surface. Moreover, the diagnosed length scales formulations showed to have very simila rbehaviour when turbulence ceases in stable conditions. The ageostrophic mass flux was higher in simulations with stronger diffusion, except that the new TKE scheme in one test case showed similar values as the operational parametrization.

Tidskriftsartikel (refereegranskat)abstract
- Recent molecular studies have identified substantial fungal diversity in indoor environments. Fungi and fungal particles have been linked to a range of potentially unwanted effects in the built environment, including asthma, decay of building materials, and food spoilage. The study of the built mycobiome is hampered by a number of constraints, one of which is the poor state of the metadata annotation of fungal DNA sequences from the built environment in public databases. In order to enable precise interrogation of such data – for example, “retrieve all fungal sequences recovered from bathrooms” – a workshop was organized at the University of Gothenburg (May 23-24, 2016) to annotate public fungal barcode (ITS) sequences according to the MIxS-Built Environment annotation standard (http://gensc.org/mixs/). The 36 participants assembled a total of 45,488 data points from the published literature, including the addition of 8,430 instances of countries of collection from a total of 83 countries, 5,801 instances of building types, and 3,876 instances of surface-air contaminants. The results were implemented in the UNITE database for molecular identification of fungi (http://unite.ut.ee) and were shared with other online resources. Data obtained from human/animal pathogenic fungi will furthermore be verified on culture based metadata for subsequent inclusion in the ISHAM-ITS database (http://its.mycologylab.org).

Tidskriftsartikel (refereegranskat)abstract
- Background and purpose - Swedish clinical guidelines for osteoarthritis (OA) prioritize patient education, exercise, and-if necessary-weight reduction before considering adjunct pharmacological intervention. Contrariwise, we investigated the proportion and type of dispensed analgesic prescriptions in Sweden received by patients during 3 years before commencing non-pharmacological primary care interventions for OA (2008-2016) compared with the general population. Furthermore, we analyzed the proportion of analgesic prescriptions dispensed before (2008-2012) compared with after (2012-2016) guideline publication in terms of concordance with clinical guideline recommendations. Patients and methods - Patients with hip or knee OA (n = 72,069) from the Better Management of OA national quality register receiving non-pharmacological interventions in primary care between 2008 and 2016 were included (OA cohort). An age, sex, and residence matched reference cohort (n = 216,207) was formed from the Swedish Total Population Register. Based on a period 3 years prior to inclusion in the OA cohort, Swedish Prescribed Drug Register data was linked to both the OA and reference cohorts. Results - Compared with the reference cohort, a distinctly larger proportion of the OA cohort had dispensed prescriptions for most types of analgesics, increasing exponentially each year prior to commencing non-pharmacological intervention. Since guideline publication, the proportion of the OA cohort having no dispensed prescription analgesics prior to non-pharmacological primary care intervention concordantly increased by 5.0% (95% CI 4.2-5.9). Furthermore, dispensed prescriptions concordantly decreased for non-selective NSAIDs -8.6% (CI -9.6 to -7.6), weak opioids -6.8% (CI -7.7 to -5.9), glucosamine -9.5% (CI -9.8 to -8.8). and hyaluronic acid -1.6% (CI -1.8 to -1.5) but discordantly increased for strong opioids 2.8% (CI 2.1-3.4) and glucocorticoid intra-articular injection for hip OA 2.1% (CI 1.0-3.1). Interpretation - In Sweden, dispensed prescription of analgesics commonly occurred before initiating non-pharmacological primary care interventions for OA but reduced modestly after guideline publication, which prioritizes non-pharmacological before pharmacological interventions. Additional modest improvements occurred in the stepped-care prioritization of analgesic prescription types. However, future strategies are required to curb an increase of strong opioids prescription for OA and glucocorticoid intra-articular injection for hip OA.
