- This study examines if interdisciplinary teaching can be said to facilitate the learning and use of fractions by Swedish 12-year-old pupils. Home and Consumer Studies is well suited to interdisciplinary teaching, and young people can therefore find it interesting to study maths since the setting is relevant to them. Building on variation theory and a learning study, we examined pupils' (n18) ability to double fractions greater than ½ when using a recipe. The general results show that what is to be learned benefits if it is presented in different ways, that teachers should not take pupils' knowledge for granted, and mathematically that it is not necessary to divide something to be able to double it. We argue that the study shows that genuine problems based on pupils' interest and life world can enhance motivation and, in turn, learning.

- Recipes are not only part of today's cooking culture, they are also part of the Swedish syllabus of home economics. The aim of this study was to investigate what kinds of difficulties students with mild intellectual disabilities have using recipes during cooking lessons in home economics. We conducted an ethnographically inspired approach, with a total of 44h of accompanying observations. Three compulsory schools for students with intellectual disabilities were enrolled in the study, and 37 students and three teachers were included. The socio-cultural theory of learning has been used as a theoretical framework. The findings reveal both that recipes are central artefacts during the cooking lessons and that the students have various difficulties using the recipes. The difficulties vary, and they concern both how the recipes are designed and the purport of the recipes. Difficulties in relation to the design included, for example, the separation of ingredients and instructions in the text and the large amount of information given in both the whole and the parts of the recipes. The difficulties in relation to the purport – that is, the meaning or sense of the recipe – were the ingredients, the kitchen utensils and the knowledge of how to perform a specific task. These difficulties can be considered special in relation to the use of the recipes. We suggest the concept of ‘recipe literacy’ to capture the complex knowledge of using recipes.

- The aim of this study was to explore what arithmetical understanding is needed when students with mild intellectual disabilities use recipes during practical cooking lessons in Home Economics. The settings were compulsory schools in Sweden attended by students with intellectual disabilities. Sixteen lessons in Home Economics during which cooking took place were observed. In total, 37 students and three teachers participated. All students had a mild intellectual disability. Their ages varied, but most were between 13 and 14 years old. The sociocultural perspective on learning, combined with a literacy framework, was used as a theoretical foundation for the study. Main findings are that students need an arithmetical understanding of (i) how to interpret numbers, (ii) how to interpret and use units, and (iii) how to compute when using recipes. The knowledge and skills needed to be able to use a recipe are featured in the concept recipe literacy, capturing both theoretical, declarative knowledge and the more practical, procedural knowledge. Recipe literacy can be used to theorize the use of recipes when learning to cook, as in Home Economics.

- Disease can have sever impact on animal populations, especially in rare species. Baseline data for atypical host species are missing for a range of infectious diseases, although such hosts are potentially more affected than the normal vectors and reservoir species. If highly pathogenic avian influenza strikes rare birds of prey, this may have crucial impact on the predator species itself, but also on the food web in which it interacts. Here we present the first large-scale screening of raptors that regularly consume birds belonging to the natural reservoir of influenza A viruses. Influenza A virus prevalence was studied in two rare raptors, the white-tailed sea eagle (Haliaetus albicilla) and the peregrine falcon (Falco peregrinus). Nestlings were screened for active (181 white-tailed sea eagles and 168 peregrine falcons) and past (123 white-tailed sea eagles and 6 peregrine falcons) infection in 2006-2007, and an additional 20 succumbed adult white-tailed sea eagles were sampled in 2003-2006. Neither high- nor low-pathogenic influnza infections were found in our sample, but this does not rule out that the former may have major impact on rare raptors and their food webs.

- Here, we aimed to investigate potential effects of ocean acidification on antimicrobial peptide (AMP) activity in the gills of Mytilus edulis, as gills are directly facing seawater and the changing pH (predicted to be reduced from ∼8.1 to ∼7.7 by 2100). The AMP activity of gill and haemocyte extracts was compared at pH 6.0, 7.7 and 8.1, with a radial diffusion assay against Escherichia coli. The activity of the gill extracts was not affected by pH, while it was significantly reduced with increasing pH in the haemocyte extracts. Gill extracts were also tested against different species of Vibrio (V. parahaemolyticus, V. tubiashii, V. splendidus, V. alginolyticus) at pH 7.7 and 8.1. The metabolic activity of the bacteria decreased by ∼65–90%, depending on species of bacteria, but was, as in the radial diffusion assay, not affected by pH. The results indicated that AMPs from gills are efficient in a broad pH-range. However, when mussels were pre-exposed for pH 7.7 for four month the gill extracts presented significantly lower inhibit of bacterial growth. A full in-depth proteome investigation of gill extracts, using LC-Orbitrap MS/MS technique, showed that among previously described AMPs from haemocytes of Mytilus, myticin A was found up-regulated in response to lipopolysaccharide, 3 h post injection. Sporadic occurrence of other immune related peptides/proteins also pointed to a rapid response (0.5–3 h p.i.). Altogether, our results indicate that the gills of blue mussels constitute an important first line defence adapted to act at the pH of seawater. The antimicrobial activity of the gills is however modulated when mussels are under the pressure of ocean acidification, which may give future advantages for invading pathogens.

- Background: Currently, no available tool easily and effectively measures both the frequency, intensity and distress of symptoms among patients receiving radiotherapy. A core symptom set (fatigue, insomnia, pain, appetite loss, cognitive problems, anxiety, nausea, depression, constipation, diarrhoea and skin reaction) has been identified and assessed across oncology research to better understand the pattern of symptoms and treatment side effects.Aim: The aim was to develop a tool measuring the multiple‐symptom experience in patients undergoing radiotherapy and evaluate its psychometric properties (validity, reliability and responsiveness).Design: This study has a prospective, longitudinal and quantitative design.Methods: We developed a patient‐reported outcome questionnaire, the Radiotherapy‐Related Symptoms Assessment Scale to assess the frequency, intensity and distress associated with symptoms. Patients (n = 175) with brain tumours undergoing proton beam therapy completed the Radiotherapy‐Related Symptoms Assessment Scale and the health‐related quality of life questionnaire (EORTC QLQ‐C30) during treatment. We assessed the validity, reliability and responsiveness of the Radiotherapy‐Related Symptoms Assessment Scale and evaluated the validity against QLQ‐C30.Results: There were significant questionnaire–questionnaire correlations regarding selected items, primarily fatigue, insomnia and pain, indicating satisfactory criterion‐related validity. The Radiotherapy‐Related Symptoms Assessment Scale had fair to good retest reliability.Conclusion: The Radiotherapy‐Related Symptoms Assessment Scale is a valid instrument for assessing symptom intensity and distress in patients with brain tumour undergoing PBT, with psychometric properties within the expected range. The Radiotherapy‐Related Symptoms Assessment Scale provides nurses with substantial information on symptom experience but requires little effort from the patient. Additional studies are required to further assess the psychometric properties in patients with different cancer diagnoses receiving conventional radiotherapy.

Tidskriftsartikel (refereegranskat)abstract
- Introduction: The scored Patient-Generated Subjective Global Assessment (PG-SGA©) is a validated tool for the screening, assessment and monitoring of malnutrition, and triaging of interventions. It contains a patient-generated component and a healthcare professional (HCP)-generated component. Aim: To translate the PG-SGA into Swedish, assess the linguistic and content validity of the Swedish version, and ensure conceptional, semantic and operational equivalence to the original English PG-SGA. Methods: In line with the methodology used in previously translated and culturally adapted versions, the standardised 10-step process suggested by the International Society for Health Economics and Outcomes Research (ISPOR) was followed. In step 7, a cross-sectional study targeting patients n = 51 and HCPs n = 52 was performed at a university hospital in Sweden. Using separate questionnaires, patients assessed the patient component and HCPs, the professional component regarding perceived comprehensibility and difficulty (linguistic validity). The HCPs also assessed perceived relevance (content validity) of all items on the PG-SGA. Item indices for comprehensibility (I-CI), difficulty (I-DI) and content validity (I-CVI) were calculated and averaged into scale indices (S-CI, S-DI and S-CVI). Cut-off standards for item and scale indices were used as reference. Results: The Swedish version of the PG-SGA rated excellent for comprehensibility (S-CI 0.96) and difficulty (S-DI 0.93) for the patient component. The professional component rated acceptable for comprehensibility (S-CI 0.89) and below acceptable for difficulty (S-DI 0.70), with the physical examination rated most difficult (I-DI 0.39 to 0.69). Content validity for the full Swedish PG-SGA was rated excellent (S-CVI 0.94). Conclusion: The patient component was considered clear and easy to complete. The full Swedish PG-SGA was considered relevant by HCPs for screening and assessment of malnutrition. Due to perceived difficulty with the physical examination, training of Swedish HCPs in using the PG-SGA is essential before implementing the professional component into clinical practice or research.

Tidskriftsartikel (refereegranskat)abstract
- Background: Remote assessment of respiratory tract infections (RTIs) has been a controversial topic during the fast development of private telemedicine providers in Swedish primary health care. The possibility to unburden the traditional care has been put against a questionable quality of care as well as risks of increased utilization and costs. The COVID-19 pandemic has contributed to a changed management of patient care to decrease viral spread, with an expected shift in contact types from in-person to remote ones. Objective: The main aim of this study was to compare health care consumption and type of contacts (in-person or remote) for RTIs before and during the COVID-19 pandemic. The second aim was to study whether the number of follow-up contacts after an index contact for RTIs changed during the study period, and whether the number of follow-up contacts differed if the index contact was in-person or remote. A third aim was to study whether the pattern of follow-up contacts differed depending on whether the index contact was with a traditional or a private telemedicine provider. Methods: The study design was an observational retrospective analysis with a description of all index contacts and follow-up contacts with physicians in primary care and emergency rooms in a Swedish region (Skane) for RTIs including patients of all ages and comparison for the same periods in 2018, 2019, and 2020. Results: Compared with 2018 and 2019, there were fewer index contacts for RTIs per 1000 inhabitants in 2020. By contrast, the number of follow-up contacts, both per 1000 inhabitants and per index contact, was higher in 2020. The composition of both index and follow-up contacts changed as the share of remote contacts, in particular for traditional care providers, increased. Conclusions: During the COVID-19 pandemic in 2020, fewer index contacts for RTIs but more follow-up contacts were conducted, compared with 2018-2019. The share of both index and follow-up contacts that were conducted remotely increased. Further studies are needed to study the reasons behind the increase in remote contacts, and if it will last after the pandemic, and more clinical guidelines for remote assessments of RTI are warranted.

Effects of manganese and hypoxia on coelomocyte renewal in the echinoderm, Asterias rubens (L.)
- 2010

Tidskriftsartikel (refereegranskat)abstract
- Manganese (Mn) is a naturally abundant metal and particularly so in soft-bottom oceanic sediments where it generally occurs bound in a four-valent colloidal state as MnO2. When hypoxic conditions occur in bottom waters, the metal reduces to the bioavailable ion Mn2+ and can reach concentrations known to have immunotoxic effects in the crustacean Nephrops norvegicus, reducing numbers of circulating haemocytes as a consequence. However, we have previously shown that Mn seems to have a contrasting effect on the echinoderm Asterias rubens in which it triggers the proliferation of haematopoietic cells and increases coelomocyte numbers. Since elevated Mn levels mostly co-occur with hypoxia in nature, here we investigated whether hypoxia has a negative effect on haematopoiesis. Proliferation and differentiation of coelomocytes and cells in the coelomic epithelium of A. rubens were compared after 3 days of exposure to realistic levels of Mn, hypoxia or a combination of these two parameters. We can confirm that Mn elevated numbers of coelomocytes and increased proliferation of epithelial cells, but hypoxia did not affect these levels. However, hypoxia did affect differentiation of these cells as judged by investigating the expression of a Runt domain transcription factor, which was also cloned and sequenced. Through comparative quantification using a real time PCR technique, we found that exposure to hypoxia had a clearly stimulating effect on mRNA expression of Runt gene in both coelomocytes and epithelial cells. These results indicate that during hypoxic conditions the composition of coelomocyte sub-populations changed. (c) 2010 Elsevier B.V. All rights reserved.
