- The PREDICTS project-Projecting Responses of Ecological Diversity In Changing Terrestrial Systems (www.predicts.org.uk)-has collated from published studies a large, reasonably representative database of comparable samples of biodiversity from multiple sites that differ in the nature or intensity of human impacts relating to land use. We have used this evidence base to develop global and regional statistical models of how local biodiversity responds to these measures. We describe and make freely available this 2016 release of the database, containing more than 3.2 million records sampled at over 26,000 locations and representing over 47,000 species. We outline how the database can help in answering a range of questions in ecology and conservation biology. To our knowledge, this is the largest and most geographically and taxonomically representative database of spatial comparisons of biodiversity that has been collated to date; it will be useful to researchers and international efforts wishing to model and understand the global status of biodiversity.

- Biodiversity continues to decline in the face of increasing anthropogenic pressures such as habitat destruction, exploitation, pollution and introduction of alien species. Existing global databases of species' threat status or population time series are dominated by charismatic species. The collation of datasets with broad taxonomic and biogeographic extents, and that support computation of a range of biodiversity indicators, is necessary to enable better understanding of historical declines and to project - and avert - future declines. We describe and assess a new database of more than 1.6 million samples from 78 countries representing over 28,000 species, collated from existing spatial comparisons of local-scale biodiversity exposed to different intensities and types of anthropogenic pressures, from terrestrial sites around the world. The database contains measurements taken in 208 (of 814) ecoregions, 13 (of 14) biomes, 25 (of 35) biodiversity hotspots and 16 (of 17) megadiverse countries. The database contains more than 1% of the total number of all species described, and more than 1% of the described species within many taxonomic groups - including flowering plants, gymnosperms, birds, mammals, reptiles, amphibians, beetles, lepidopterans and hymenopterans. The dataset, which is still being added to, is therefore already considerably larger and more representative than those used by previous quantitative models of biodiversity trends and responses. The database is being assembled as part of the PREDICTS project (Projecting Responses of Ecological Diversity In Changing Terrestrial Systems - ). We make site-level summary data available alongside this article. The full database will be publicly available in 2015.

- Background: We aimed to evaluate differences in outcome between patients admitted to intensive care unit (ICU) after elective versus acute surgery in a multinational cohort of very old patients (80 years; VIP). Predictors of mortality, with special emphasis on frailty, were assessed.Methods: In total, 5063 VIPs were induded in this analysis, 922 were admitted after elective surgery or intervention, 4141 acutely, with 402 after acute surgery. Differences were calculated using Mann-Whitney-U test and Wilcoxon test. Univariate and multivariable logistic regression were used to assess associations with mortality.Results: Compared patients admitted after acute surgery, patients admitted after elective surgery suffered less often from frailty as defined as CFS (28% vs 46%; p < 0.001), evidenced lower SOFA scores (4 +/- 5 vs 7 +/- 7; p < 0.001). Presence of frailty (CFS >4) was associated with significantly increased mortality both in elective surgery patients (7% vs 12%; p = 0.01), in acute surgery (7% vs 12%; p = 0.02).Conclusions: VIPs admitted to ICU after elective surgery evidenced favorable outcome over patients after acute surgery even after correction for relevant confounders. Frailty might be used to guide clinicians in risk stratification in both patients admitted after elective and acute surgery.

Metal additive manufacturing and possible clinical markers for the monitoring of exposure-related health effects
- 2021

Ingår i: PLOS ONE. - : Public Library of Science. - 1932-6203. ; 16:3

Tidskriftsartikel (refereegranskat)abstract
- Additive manufacturing (AM) includes a series of techniques used to create products, in several different materials, such as metal, polymer or ceramics, with digital models. The main advantage of AM is that it allows the creation of complex structures, but AM promises several additional advantages including the possibility to manufacture on demand or replacing smaller worn parts by directly building on an existing piece. Therefore, the interest for and establishment of AM is rapidly expanding, which is positive, however it is important to be aware that new techniques may also result in new challenges regarding health and safety issues. Metals in blood and possible clinical effects due to metal exposure were investigated in AM operators at one of the first serial producing AM facilities in the world during two consecutive years with implementation of preventive measures in-between. As comparison, welders and office workers as control group were investigated. Health investigations comprised of surveys, lung function tests, antioxidant activity and vascular inflammation as well as renal- and hepatic function analysis. AM operators had significantly reduced nickel levels in blood (10.8 vs 6.2 nmol/L) as well as improved lung function (80 vs 92% of predicted) from year 1 to year 2. This is in line with previously published results displaying reduced exposure. Blood cobalt and nickel levels correlated with previously reported urinary levels, while blood chromium did not. Multivariate modelling showed that blood cobalt, antioxidant/inflammatory marker serum amyloid A1/serum paraoxonase/arylesterase 1 activity and the hepatic markers aspartate transaminase, alanine transaminase, and alkaline phosphatase were higher in AM operators compared to controls. The study show that the selected clinical analyses could function as a complement to metal analyses in biological fluids when investigating exposure-related health effects in AM operators. However, validation in larger cohorts is necessary before more definite conclusions could be drawn.

- Background and aim: Adequate velopharyngeal function and speech are main goals in the treatment of cleft palate. The objective was to investigate if there were differences in velopharyngeal competency (VPC) and hypernasality at age 5 years in children with unilateral cleft lip and palate (UCLP) operated on with different surgical methods for primary palatal repair. A secondary aim was to estimate burden of care in terms of received additional secondary surgeries and speech therapy. Design: Three parallel group, randomised clinical trials were undertaken as an international multicentre study by 10 cleft teams in five countries: Denmark, Finland, Sweden, Norway, and the UK. Methods: Three different surgical protocols for primary palatal repair were tested against a common procedure in the total cohort of 448 children born with a non-syndromic UCLP. Speech audio and video recordings of 391 children (136 girls, 255 boys) were available and perceptually analysed. The main outcome measures were VPC and hypernasality from blinded assessments. Results: There were no statistically significant differences between the prevalences in the arms in any of the trials. VPC: Trial 1, A: 58%, B: 61%; Trial 2, A: 57%, C: 54%; Trial 3, A: 35%, D: 51%. No hypernasality: Trial 1, A: 54%, B: 44%; Trial 2, A: 47%, C: 51%; Trial 3, A: 34%, D: 49%. Conclusions: No differences were found regarding VPC and hypernasality at age 5 years after different methods for primary palatal repair. The burden of care in terms of secondary pharyngeal surgeries, number of fistulae, and speech therapy visits differed.

- Overall weighted or composite variables for perceptual auditory estimation of velopharyngeal closure or competence have been used in several studies for evaluation of velopharyngeal function during speech. The aim of the present study was to investigate the validity of a composite score (VPC-Sum) and of auditory perceptual ratings of velopharyngeal competence (VPC-Rate). Available VPC-Sum scores and judgments of associated variables (hypernasality, audible nasal air leakage, weak pressure consonants, and non-oral articulation) from 391 5-year olds with repaired cleft palate (the Scandcleft project) were used to investigate content validity, and 339 of these were compared with an overall judgment of velopharyngeal competence (VPC-Rate) on the same patients by the same listeners. Significant positive correlations were found between the VPC-Sum and each of the associated variables (Cronbachs alpha 0.55-0.87, P amp;lt; 0.001), and a moderately significant positive correlation between VPC-Sum and VPC-Rate (Rho 0.698, P amp;lt; 0.01). The latter classified cases well when VPC-Sum was dichotomized with 67% predicted velopharyngeal competence and 90% velopharyngeal incompetence. The validity of the VPC-Sum was good and the VPC-Rate a good predictor, suggesting possible use of both measures depending on the objective.

Konsten att undervisa ryttare : En studie om ridlärares pedagogiska praktik
- 2020
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis concerns how riding teachers’ reflect upon their teaching and how they teach. The overall aim of the thesis is to contribute with knowledge about how riding lessons are organized, regarding both the accomplishment of lessons as activity systems and the interactional organization of instructional work. Horseback riding can be understood as an embodied and practical knowledge, and includes communication and collaboration between horse and rider, sometimes referred to as equestrian feel (Dashper, 2016). Two different theoretical perspectives were applied to explore how such knowledge is taught. Activity theory (Engeström, 1987) was used to analyze interviews with and observations of ten riding teachers about their understanding and implementation of their pedagogical practice. Teachers’ and students’ interactions during riding lessons were examined using an ethnomethodological and conversation analytic approach (Goodwin, 2000; Schegloff, 1996). The analyses were based on video-recordings of ten group lessons and 40 one-on-one riding lessons.The results show that riding lessons can be conceptualized as activity systems where the focus of teaching constantly changes; from horse to student to routine. Traditions and safety regulations are shown to generate contradictions that may hinder the teachers from developing their teaching. However, the teachers express a wish to use more student collaborative methods, and display an intention to communicate with students about equestrian feel. Another result unveils how the teacher and the individual students, within the mobile context of riding lessons, make instructional sequences possible by co-creating instructional spaces. A third result illuminates the participants’ collaborative work to make equestrian feel available for instruction. The teacher molds equestrian feel through online instructions, i.e., instructions produced during the students’ active riding. These instructions shift focus between the students’ seat and influence, the horse’s actions and the student’s embodied feel. Moreover, the teachers are shown to use visual, verbal and embodied resources as they interpret equestrian feel for the student. In sum, the studies shed light on the complex art of teaching practical and embodied knowledge of riding.

Ingår i: Book of Abstracts. - : Sveriges Lantbruksuniversitet. ; , s. 23-23

Konferensbidrag (refereegranskat)abstract
- This paper presents the results of a pilot study including a questionnaire and semi-structured interviews with riders about their reading of horse stories. The data has been collected at an equestrian center in Sweden. The informants are active at the riding center and thus of various ages, although approximately 75 percent are 20 years old or more. They have been asked questions on their reading habits when it comes to horse stories, at present or at earlier stages in their lives. Interviews are ongoing but results are expected to come in the next couple of months. The purpose of the interviews is foremost to enter more deeply into the informants’ reading of horse stories.Tentative results show that 80 percent of the informants read horse stories in the age between 8 to 12 years. 75 percent of the adults report that they used to read horse stories either every day or between one and three times per week in that particular age. 60 percent state that horse stories were important for them since they got the opportunity to dream away, identify themselves with the characters and relate to their own experiences from the equestrian settings, to learn new things about horses and riding and, finally, as a reaction to the fact that they could not spend as much time in the stable as they would have preferred. In addition, a majority of the informants suggest that horse stories could be used at equestrian centers, for both educational and relaxational reasons.
