    The impact of worksite interventions promoting healthier food and/or physical activity habits among employees working 'around the clock' hours: a systematic review2018In: Food & nutrition research, ISSN 1654-661X, Vol. 62Article in journal (Refereed)
    Abstract [en]

    We conducted a systematic review of randomised studies on the impact of worksite interventions to promote healthier food and/or physical activity among people who work irregular hours 'around the clock', that is, outside of ordinary daytime working hours. The population-intervention-comparator-outcomes-study (PICOS) design format was used. Data sources were PubMed and CINAHL. An updated search was conducted on October 2017 using Google Scholar and the related articles function in PubMed on initially included studies to identify additional studies. Risk of bias was used to assess study quality. A total of seven studies (reports published in 14 papers) were included in the systematic review: Two interventions with a broader lifestyle approach, three focusing on physical exercise and two on providing healthier food or meal options. The studies had sample sizes from 30 to 1,000 and targeted a mixture of occupations, including both male- and female-dominated occupational groups. The interventions lasted from 2 to 12 months. Only one had an extended follow-up. In general, the studies showed small-to-moderate effect sizes on several measures, including dietary and/or physical activity measures, suggesting acceptable effectiveness for interventions involving community-level behaviour change. Our findings highlight a need to further develop and implement well-designed health promotion interventions with comparable outcome measures and effect size reports. A mixture of health promotion strategies is recommended for future practice in this target population, including individually tailored programmes, improving the food and physical activity environment and using broader lifestyle approaches including the use of participatory and empowerment strategies. While more research is needed in this field, the existing knowledge base on effective approaches awaits translation into practice.

    Aktivt Åldrande – individuellt anpassade måltidslösningar för hälsa och livskvalitet hos äldre: beställning och distribution av mat för den äldre2015Report (Other academic)
    Abstract [en]

    ”Active Ageing – Personalised food and meal solutions for health and quality of life” (Aktivt åldrande – individuellt anpassade måltidslösningar för hälsa och livskvalitet hos äldre. Diarienr 2013-02780) is a project that aims to maintain the quality of life and autonomy of older persons, through individual and personalised meal solutions that fit their needs and requirements. The target group are primarily the age 75 or older. Five work packages are included in the project. This report describes the work package that had the scope of developing a concept for the ordering, distribution and delivery of meal to the elderly. Refrigeration technology and the cold-chain will play an important role in the concept by preserving the safety and quality of foods during its transportation to the elderly. Refrigeration technology and the cold-chain will also make it possible to prepare specific types of foods that meet the demand of the elderly. In particular for the elderly consumers that would like to eat at home and decrease their independency and overall quality of life. It is also important the value chain and concept for the business model must be flexible and taking into account needs from the elderly consumers at all stages, starting from ordering the meal, handling in the household and disposing of the packaging material. An interdisciplinary approach – combining knowledge of ICT (information and communications technology) – Technology, food quality, packaging, logistic, sensory, and waste/return systems for the food that is distributed is increasingly necessary. As the demand for food for the elderly is on the rise, the development of new products, models and services might be facilitated by collaborating with SMEs (micro, small and mediumsized enterprises) and other business partners interested in delivering solutions for the elderly consumers. The concept for the ordering, distribution and delivery of meal to the elderly developed in the project can be used by other end users and/or for other products and services.

    Preferences, needs and attitudes regarding food habits and meal patterns among community-dwelling older adults: a cross-sectional survey2017In: Exploring Future Foodscapes: 10th International Conference on Culinary Arts and Sciences / [ed] Bent Egberg Mikkelsen m.fl, AAU Captive Food Studies Group , 2017Conference paper (Refereed)
    Abstract [en]

    The aim of this study is to explore preferences, needs and attitudes regarding food habits and meal patterns among community-dwelling older adults. 164 community-dwelling, 87-100-years old, 73 % women. Cross-sectional questionnaires based survey distributed by postal service. Approved by the Regional Ethical Review board in Gothenburg T231-14, addition to Dnr ref nr: 650-07. Results were, meanage 90.6 ± 2.84 yrs, mean BMI 23.7 ± 3.70 kg/m2, ♀71, ♂31 had no medical difficulties. More women than men lived alone, ♀102 ♂21 (p<0.01). ♀75 ♂28 would not consider home delivered convenience meals and ♀101 ♂23 cooked alone. Top three important practicalities when buying or receiving convenience meals were easy-open package (♀64 ♂23), easy to get food out (♀34 ♂13) and easily read (♀31 ♂16). This very old population shows good health evident by nutritional status and meal patterns. Subject characteristics indicated better condition than average Swedish nonagenarian, a minority reporting medical difficulties. Very few would consider convenience meals home delivered and would never use the computer. The conclusion is that an majority of both sexes preferred and managed planning, acquiring and cooking food independently although gender differences were apparent with women taking a greater responsibility. A great proportion was interested in testing new flavors. An urgent need concerned accessible containers with readable labels showing the importance for industry to acknowledge needs of older adults and accordingly adapt packaging for this age group.

    Small and large PROS1 deletions but no other types of rearrangements detected in patients with protein S deficiency2012In: Thrombosis and Haemostasis, ISSN 0340-6245, Vol. 108, no 1, p. 94-100Article in journal (Refereed)
    Abstract [en]

    Protein S deficiency is a dominantly inherited disorder that results from mutations in the PROS1 gene. Previous sequencing of the gene failed to detect mutations in eight out of 18 investigated Swedish families, whereas segregation analyses detected large deletions in three out of the eight families. The present study investigates more thoroughly for the presence of deletions but also for other types of rearrangements. FISH analysis confirmed the existence of the three previously identified large deletions, but failed to identify any other type of rearrangement among the eight analysed families. MLPA analysis of the PROS1 gene revealed two smaller deletions covering two and four exons, respectively. Thus, deletions could be found in five out of eight families where no point mutations could be found despite sequencing of the gene. Twelve additional, not previously analysed, families were subsequently analysed using MLPA. The analysis identified two smaller deletions (3 and 4 exons). Including all PS-deficient families, i.e. also the 10 families where sequencing found a causative point mutation, deletions were identified in seven out of 30 PS-deficient families. A strategy of sequencing followed by MLPA analysis in mutation-negative families identified the causative mutation in 15 out of 18 of Swedish PS-deficient families. Most deletions were different as determined by their sizes, locations and flanking haplotypes. FISH (8 families) and MLPA analysis (20 families) failed to identify other types of rearrangements.

    Genetic variation in the syntaxin-binding protein STXBP5 in type 1 von Willebrand disease patients2018In: Thrombosis and haemostasis, ISSN 2567-689X, Vol. 118, no 8, p. 1382-1389Article in journal (Refereed)
    Abstract [en]

    von Willebrand factor (VWF) levels in healthy individuals and in patients with type 1 von Willebrand disease (VWD) are influenced by genetic variation in several genes, for example, VWF, ABO and STXBP5. Here, we comprehensively screen for STXBP5 variants and investigate their association with type 1 VWD in Swedish patients and controls. The coding region of the STXBP5 gene was re-sequenced in 107 type 1 VWD patients and the detected variants were genotyped in the type 1 VWD population and a Swedish control population (464 individuals). The functional effects of missense alleles were predicted in silico and the pattern of genetic variation in STXBP5 was analysed. Re-sequencing of 107 type 1 VWD patients identified three missense and three synonymous variants in the coding sequence of STXBP5. The low-frequency missense variants rs144099092 (0.005) and rs148830578 (0.029) were predicted to be damaging, but were not accumulated in patients. No other rare candidate mutations were detected. STXBP5 showed a high level of linkage disequilibrium and a low overall nucleotide diversity of π = 3.2 × 10-4 indicating intolerance to variants affecting protein function. Three previously type 1 VWD-associated single nucleotide polymorphisms were located on one haplotype that showed an increased frequency in patients versus controls. No differences in messenger ribonucleic acid abundance among haplotypes could be found using Genotype-Tissue Expression project data. In conclusion, a haplotype containing the STXBP5 Asn436Ser (rs1039084) mutation is associated with type 1 VWD and no rare STXBP5 mutations contribute to type 1 VWD in the Swedish population.

    Nutritional quality of children’s diet and associations with parental cooking skills and nutritional awareness2017Independent thesis Advanced level (degree of Master (Two Years)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: Child overweight and obesity are increasing public health problems and food habitsamong children are concerning. Healthy family food habits and basic parental nutrition and cooking skills are important for ensuring children receive an adequate diet.

    Objective: To explore the nutritional quality of 5-10-year-old Swedish children’s diets and associations with parental self-perceived cooking skills, awareness of nutrition guidelines, family cooking practices and demographic variables.

    Methods: A cross sectional online survey was responded by 72 parents. Nutritional quality was measured using The National Board of Health and Wellness’ Dietary Index. The survey also measured parental self-perceived cooking skills, awareness of nutrition guidelines, family cooking practices and demographic variables. Associations were tested with independent t-tests and Spearman rank correlations.

    Results: Mean Dietary Index score was 8.11, which indicates an unsatisfactory adherence to Nutrition Guidelines. Children’s food habits in this sample were better than in the national survey Riksmaten barn 2003, but intake levels of fruit, vegetables and fish was still below recommendations. Associations were found between children’s Dietary Index scores and parental cooking skills, nutritional awareness and frequency of child participating in cooking. No associations with demographic variables were found.

    Conclusions: Children’s diets are not in line with recommendations for 46 % of the participants, but appears to have improved since the latest national survey. Parental cooking skills, nutritional awareness and children participating in cooking more often was associated with better nutritional quality in children.The small sample size, participant heterogeneity and the recruitment method limits the generalizability of the results.

    Normalvärden och F-waves vid registrering på tibialis anterior vid undersökning av peroneus communis med elektroneurografi2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Electroneurography is used to examine a suspected entrapmentneuropathy in peroneus communis (PC), where an electric stimulus enables the evaluation of nerve conduction velocity, muscle response amplitude and latency. If registration from the extensor digitorum brevis (EDB) provides unreliable results, the registration can be made from tibialis anterior (TA). Currently there are no normal values available in our laboratory and no standard method regarding the registration on TA. The purpose of this study was therefore to retrieve normal values for this registration and to develop and establish a method, and also compare the different registration sites, to examine the side differences from the registrations on TA, and how the height affected the latency. It was also examined if so called F-waves could be recorded from TA, and if so, determine the response rate and latency. 22 participants between 23-59 years an 154-190 cm were examined. TA was examined with the active registration electrode on the site where the muscle was the largest and the reference electrode on the ankle. Stimulations were made on lateral poplitea fossa and 110 mm lower on distal caput fibula. EDB were examined according to established methods. Normal values for the registration on TA were 2,2-5,4 mV regarding amplitude, 55-73 m/s regarding nerve conduction velocity and 3,8-5,9 ms regarding latency. Side differences were 0-1,4 mV regarding amplitude, 0-8 m/s regarding nerve conduction velocity and 0-0,8 ms regarding latency. The calculated limits show that it only takes small side differences to have a clinical significance. The method gave equivalent results to previous studies. 23 % of the latency could be explained by height. The comparing of the nerve conduction velocity from the different registrations showed a significant statistical, but not necessarily clinical, difference, with the bias 5 m/s. F-waves were retrieved from all participants with a response rate of 94-100 %. 41 % of the F-wave latency could be explained by height.

    Genetic variation in the C-type lectin receptor CLEC4M in type 1 von Willebrand Disease patients2018In: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 13, no 2Article in journal (Refereed)
    Abstract [en]

    von Willebrand factor (VWF) levels in healthy individuals and in patients with type 1 von Willebrand disease (VWD) are influenced by genetic variation in several genes, e.g. VWF, ABO, STXBP5 and CLEC4M. This study aims to screen comprehensively for CLEC4M variants and investigate their association with type 1 VWD in the Swedish population. In order to screen for CLEC4M variants, the CLEC4M gene region was re-sequenced and the polymorphic neck region was genotyped in 106 type 1 VWD patients from unrelated type 1 VWD families. Single nucleotide variants (SNV) and variable number tandem repeat (VNTR) allele and genotype frequencies were then compared with 294 individuals from the 1000Genomes project and 436 Swedish control individuals. Re-sequencing identified a total of 42 SNVs. Rare variants showed no accumulation in type 1 VWD patients and are not thought to contribute substantially to type 1 VWD. The only missense mutation (rs2277998, NP_001138379.1:p.Asp224Asn) had a higher frequency in type 1 VWD patients than in controls (4.9%). The VNTR genotypes 57 and 67 were observed at higher frequencies than expected in type 1 VWD patients (6.4% and 6.2%) and showed an increase in patients compared with controls (7.4% and 3.1%). Strong linkage disequilibrium in the CLEC4M region makes it difficult to distinguish between the effect of the missense mutation and the VNTR genotypes. In conclusion, heterozygous VNTR genotypes 57 and 67 of CLEC4M were highly enriched and are the most likely mechanism through which CLEC4M contributes to disease in the Swedish type 1 VWD population.

    Genetic variation in the von Willebrand factor gene in Swedish von Willebrand disease patients2018In: TH Open, ISSN 2512-9465, Vol. 2, no 1, p. 39-48Article in journal (Refereed)
    Abstract [en]

    von Willebrand factor (VWF) level and function are influenced by genetic variation in VWF and several other genes in von Willebrand disease type 1 (VWD1) patients. This study comprehensively screened for VWF variants and investigated the presence of ABO genotypes and common and rare VWF variants in Swedish VWD1 patients. The VWF gene was resequenced using Ion Torrent and Sanger sequencing in 126 index cases historically diagnosed with VWD. Exon 7 of the ABO gene was resequenced using Sanger sequencing. Multiplex ligation-dependent probe amplification analysis was used to investigate for copy number variants. Genotyping of 98 single nucleotide variants allowed allele frequency comparisons with public databases. Seven VWD2 mutations and 36 candidate VWD1 mutations (5 deletions, 4 nonsense, 21 missense, 1 splice, and 5 synonymous mutations) were identified. Nine mutations were found in more than one family and nine VWD1 index cases carried more than one candidate mutation. The T-allele of rs1063857 (c.2385T > C, p.Y795 = ) and blood group O were both frequent findings and contributed to disease in the Swedish VWD1 population. VWD2 mutations were found in 20 and candidate VWD1 mutations in 51 index cases out of 106 (48%). VWF mutations, a VWF haplotype, and blood group O all contributed to explain disease in Swedish VWD1 patients.

    Next-generation sequencing of 17 genes associated with venous thromboembolism reveals a deficit of non-synonymous variants in procoagulant genes2019In: Thrombosis and haemostasis, ISSN 2567-689X, Vol. 119, no 9, p. 1441-1450Article in journal (Refereed)
    Abstract [en]

    BACKGROUND:  The heritability of venous thromboembolism (VTE) is only partially explained by variants in 17 previously VTE-associated genes.

    OBJECTIVE:  This article screens for additional rare variants in the 17 genes and investigates the relative contributions of pro- and anticoagulant genes to VTE.

    PATIENTS AND METHODS:  Ninety-six VTE patients from the population-based Malmö Thrombophilia Study were analysed using an AmpliSeq strategy and Ion Torrent sequencing and the variant data were compared with data from public databases.

    RESULTS:  A total of 102 non-synonymous and 76 synonymous variants were identified. Forty-six non-synonymous variants were present in the human gene mutation database. Anticoagulant and procoagulant genes showed 14 and 22 rare non-synonymous variants, respectively. Individual patients showed varying numbers of risk factors; 13 patients had non-synonymous mutations in SERPINC1, PROC and PROS1 genes and 42 had factor V Leiden or prothrombin mutations generating a total of 47 patients with at least one of these risk factors. Ten common VTE-associated variants showed low level enrichments and no correlation to the other risk factors. The enrichment of previously identified risk factors was similar to previous studies. Determination of the nsyn/syn ratio (number of non-synonymous variants per non-synonymous site, nsyn, to the number of synonymous variants per synonymous site, syn) showed, as expected in patients, an increase of non-synonymous relative to synonymous anticoagulant variants compared with controls (nsyn/syn, 0.95 vs. 0.68). In contrast, non-synonymous procoagulant variants (nsyn/syn, 0.31 vs. 0.63) showed a decrease. We suggest that the deficit of non-synonymous variants in procoagulant genes is a novel mechanism contributing to VTE.

    Targeted re-sequencing of F8, F9 and VWF: characterization of Ion Torrent data and clinical implications for mutation screening.2019In: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 14, no 4Article in journal (Refereed)
    Abstract [en]

    Mutations are not identified in ~5% of hemophilia A and 10-35% of type 1 VWD patients. The bleeding tendency also varies among patients carrying the same causative mutation, potentially indicating variants in additional genes modifying the phenotype that cannot be identified by routine single-gene analysis. The F8, F9 and VWF genes were analyzed in parallel using an AmpliSeq strategy and Ion Torrent sequencing. Targeting all exonic positions showed an average read depth of >2000X and coverage close to 100% in 24 male patients with known disease-causing mutations. Discrimination between reference alleles and alternative/indel alleles was adequate at a 25% frequency threshold. In F8, F9 and VWF there was an absolute majority of all reference alleles at allele frequencies >95% and the average alternative allele and indel frequencies never reached above 10% and 15%, respectively. In VWF, 4-5 regions showed lower reference allele frequencies; in two regions covered by the pseudogene close to the 25% cut-off for reference alleles. All known mutations, including indels, gross deletions and substitutions, were identified. Additional VWF variants were identified in three hemophilia patients. The presence of additional mutations in 2 out of 16 (12%) randomly selected hemophilia patients indicates a potential mutational contribution that may affect the disease phenotype and counseling in these patients. Parallel identification of disease-causing mutations in all three genes not only confirms the deficiency, but differentiates phenotypic overlaps and allows for correct genetic counseling.

    Stark inför kirurgi – stark för livet2018Other (Other academic)
    Abstract [sv]

    Hälsosamma matvanor och god nutrition har stor betydelse för patientens autonomi, vårdbehov och rehabilitering och är grundläggande för övrig behandling. Att säkerställa att patienten har bästa möjliga nutritionsstatus inför planerad kirurgi, i det akuta efterförloppet och under sin rehabilitering har stor betydelse i omvårdnads- och läkningsprocessen. Rätt mat och näring är en viktig patientsäkerhetsfråga.Undernäring leder till sämre resultat av medicinsk och kirurgisk behandling, förlängd vårdtid och ökad risk för komplikationer, lidande och död. Säker vård avseende nutrition baseras på̊ bedömning av undernäring eller risk för undernäring, utredning av orsak samt adekvat näringsbehandling.God och säker vård är personcentrerad och evidensbaserad. Den bedrivs i team och bygger på kommunikation mellan alla inblandade.

    Potential för användning av restströmmar på ett musteri: Energibalans och klimatpåverkan vid produktion av etanol respektive biodiesel2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Ett svenskt musteri eftersträvar att öka potentialen för användning av företagets reningsslam. Musteriets övriga restströmmar är äppelrester och koncentrat. Syftet med studien är att undersöka energibalans och klimatnytta vid etanol- respektive biodieselproduktion av musteriets restströmmar. Även utbytet av biobränsle samt behov av tillsatser analyseras. Biodiesel produceras i studien av lipider från oljebildande jästsvampar. Studien baseras på litteratur samt personliga informanter. Resultatet visar att 87,5 kubikmeter motsvarande 1 859 gigajoule etanol alternativt 7,4 kubikmeter motsvarande 243 gigajoule biodiesel kan produceras. Nettoenergibalansen med biogasproduktion av restprodukter inräknad blir 1 454 gigajoule vid etanolproduktion och 734 gigajoule vid biodieselproduktion. Biogasproduktion av restprodukter ger störst bidrag till nettoenergiutbytet vid biodieselproduktion. Per år minskar klimatutsläppen med 103 ton koldioxidekvivalenter i systemet med etanolproduktion och med 23 ton koldioxidekvivalenter i systemet med biodieselproduktion med avdrag för ersatt fossilt bränsle. Vid fermenteringen behöver 8,6 ton ammoniumkväve och 16,8 ton svavel tillsättas. Vid odling av oljebildande jästsvamp behöver 1,2 ton ammoniumkväve, 11,7 ton fosfor och 0,1 ton magnesium tillsättas. pH-värdet behöver sänkas till 5,5 respektive 5,7 vid etanol- respektive biodieselproduktion. Etanolproduktion bedöms vara lämpligast på musteriet. Både etanol- och biodieselproduktion är generellt effektivare på Företaget både klimat- och energimässigt än vid biobränsleproduktion av odlade råvaror. Biobränsleproduktionen på Företaget skulle kunna effektiviseras genom inblandning av andra lokala aktörers restprodukter. Experimentella studier samt forskning kring kostnader, behov av arbetsinsatser och komplexitet är betydelsefullt i vidare analys av restströmmarnas potential. Det skulle även vara värdefullt med en utredning om möjligheten att återcirkulera koldioxid som utsöndras av jästsvamparna till algodling i vattenreningen.

    Från våta marker till våtmarker: en studie i våtmarkernas förändringar mellan tidigt 1800-tal och 2017 vid Ivösjön i nordöstra Skåne2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Våta marker utgjorde tillsammans med andra miljöer en variation i det historiska landskapet. När människor behövde den våta marken för odling betraktades den som ogynnsam och marken avvattnades. Endast 10 % av den ursprungliga våtmarksarealen finns idag kvar i Skåne. Våta marker blev begreppet våtmarker när människan förstod dess värden. I uppsatsen studeras våtmarksförändringar och markanvändningsutveckling mellan tidigt 1800-tal och 2017 vid Ivösjön i nordöstra Skåne. Uppsatsen kartlägger också hur dikningsföretag har påverkat våtmarkernas förändring.  Utifrån historiskt kartmaterial och Lantmäteriets höjddata har GIS-analyser utförts och jämförts med relevant litteratur. Våtmarkernas kvarvarande areal är mellan 9 % och 14 % och samstämmer med de generella siffrorna över Skåne, dock finns avvikelser vid ett område (43 %). Markanvändningens utveckling följer de allmänna trenderna. Hur dikningsföretagen påverkat markanvändningen kräver vidare undersökningar.

    Fruktodlingsarealens utveckling i socknarna Västra Karup och Södra Mellby mellan åren 1926 och 20142019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Det har under lång tid odlats frukt i Sverige. Fruktodlingen var länge knuten till herrgårdar och slott. Sedan slutet av 1800-talet började fruktodlingar anläggas i områdena runt Vånga, Kivik och Båstad i Skåne. Det växer fram en ny typ av näring som är mer industriellt präglad än den tidigare herrgårds- och slottsodlingen. Syftet med studien är att undersöka industrifruktodlingsarealens utveckling mellan åren 1926 och 2014 i socknarna Västra Karup vid Båstad och Södra Mellby vid Kivik. Socknarna valdes som undersökningsområden för att de ligger i två fruktodlingsdistrikt i Skåne. Metoden som används är digitalisering av fruktodlingarna i kartmaterialet och beräkning av arealen i GIS-programmet ArcMap.

     

    Fruktodlingsarealen ökade i båda socknarna under första hälften av undersökningsperioden och minskade under den andra. I Västra Karup är arealen minst i slutet av undersökningsperioden och i Södra Mellby i början, arealen var störst i båda socknarna i mitten av perioden. Ökningen beror bland annat på avskärmningen från världsmarknaden under andra världskriget samt ett importstopp på utländsk frukt och minskningen på tullar och ett borttaget importstopp.

    Diffusa rum i stadslandskapet: En fallstudie i Tomelilla tätort2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The essay deals with diffuse spaces in Tomelilla town center. Diffuse spaces are found everywhere as enclaves between buildings or in the well-defined urban landscape. They are usually located in areas that have been over after planning projects or in empty spaces andwithout a specific function. Our background study is based on previous studies on the subject that have shown that diffuse spaces have a variety of values. The values depend on the way people want to mark these diffuse spaces in the city that give us different definitions such as self-organization, spontaneity, creativity or just a simple and temporary use. Diffuse spaces are usually associated with negative social activities and are in contrast to many public spaces that contain rules and controls. On the other hand, diffuse spaces are open to different types of social groups without rules, limitations and can serve as an alternative to public space. Observations have been performed in Tomelilla town center where the observations help us understand the values diffuse rooms have for the residents. Generally speaking during sex-day observations, two in January, two in March and another two days in April, we discovered that communication and recreation values are the dominant values for these diffuse spaces. Also that these diffuse rooms firstly are used as passages in different ways.

    Evaluation of Congo red staining in degenerating porcine photoreceptors in vitro: protective effects by structural and trophic support2018In: Journal of Histochemistry and Cytochemistry, ISSN 0022-1554, E-ISSN 1551-5044, Vol. 66, no 9Article in journal (Refereed)
    Abstract [en]

    Congo red (CR) is a histological stain used for the detection of extracellular amyloids mediating various neurodegenerative diseases. Given that damaged photoreceptors appear to degenerate similarly to other nerve cells, CR staining was evaluated in experimentally injured porcine retina. CR staining appeared mostly as discrete cytosolic deposits with no obvious plaque formation during the investigated time period. Increases of CR labeling coincided temporally with the known accumulation of mislocalized opsins and increases of cell death. Coculture, either with human retinal pigment epithelium (ARPE) or human neural progenitor (ReN) cells, was accompanied by a significant reduction of CR labeling. Of particular interest was the reduction of CR labeling in cone photoreceptors, which are important for the perception of color and fine details and afflicted in age-related macular degeneration (AMD). Electron microscopy revealed inclusions in the inner segment, cell body, and occasionally synaptic terminals of photoreceptor cells in cultured specimens. Closer examinations indicated the presence of different types of inclusions resembling protein aggregates as well as inclusion bodies. The current results indicate that injury-related response resulted in accumulation of CR deposits in photoreceptor cells, and that trophic and/or structural support attenuated this response.

    The common VWF single nucleotide variants c.2365A>G and c.2385T>C modify VWF biosynthesis and clearance2018In: Blood advances, ISSN 2473-9537, Vol. 2, no 13, p. 1585-1594Article in journal (Refereed)
    Abstract [en]

    Plasma levels of von Willebrand factor (VWF) vary considerably in the general population and this variation has been linked to several genetic and environmental factors. Genetic factors include 2 common single nucleotide variants (SNVs) located in VWF, rs1063856 (c.2365A>G) and rs1063857 (c.2385T>C), although to date the mechanistic basis for their association with VWF level is unknown. Using genotypic/phenotypic information from a European healthy control population, in vitro analyses of recombinant VWF expressing both SNVs, and in vivo murine models, this study determined the precise nature of their association with VWF level and investigated the mechanism(s) involved. Possession of either SNV corresponded with a significant increase in plasma VWF in healthy controls (P < .0001). In vitro expression confirmed this observation and highlighted an independent effect for each SNV (P < .0001 and P < .01, respectively), despite close proximity and strong linkage disequilibrium between them both. The influence of c.2365A>G on VWF levels was also confirmed in vivo. This increase in VWF protein corresponded to an increase in VWF messenger RNA (mRNA) resulting, in part, from prolonged mRNA half-life. In addition, coinheritance of both SNVs was associated with a lower VWF propeptide-to-VWF antigen ratio in healthy controls (P < .05) and a longer VWF half-life in VWF knockout mice (P < .0001). Both SNVs therefore directly increase VWF plasma levels through a combined influence on VWF biosynthesis and clearance, and may have an impact on disease phenotype in both hemostatic and thrombotic disorders.

    Nedfrysning av nötkött – ett sätt att minska matsvinn?: Konsumenters inställning till att köpa nötkött som frysts ner dagen innan bäst före datum har passerat kopplat till food literacy.2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Introduction: food waste contributes to a negative climate impact and the meat wastage, especially beef, generates large amounts of greenhouse gas emissions per kilogram beef. Reducing animal wastage should be a priority in order to quickly reduce greenhouse gas emissions.

    Aim: The aim is to investigate consumers' attitude to buying beef that has been frozen the day before the best before date has passed in an attempt to reduce the meat wastage.

    The study also investigates whether food-related knowledge, skills and behaviors, summarized in the concept food literacy, affect the attitude of buying beef that has been frozen the day before the best before date has passed.

    Method: Data was collected using a web-questionnaire and a focus group. The processing and the analysis of the data was performed in Excel using Chi-Square tests. The qualitative data was transcribed and analyzed using coding and thematization.

    Results: The quantitative data shows a positive trend where the majority of consumers can see themselves buying beef that has been frozen the day before the best before date has passed. The results show that the level of food literacy increases with age. Factors that prove to be important for consumers are price, quality, packaging and origin.

    Conclusion: The majority of respondents regardless of age are positive about buying beef. The result indicates that the proportion of respondents with a high degree of food literacy increases with age and factors that prove to be important for consumers when buying beef are price, quality, packaging and origin.

    Human Activity Recognition: Deep learning techniques for an upper body exercise classification system2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Most research behind the use of Machine Learning models in the field of Human Activity Recognition focuses mainly on the classification of daily human activities and aerobic exercises. In this study, we focus on the use of 1 accelerometer and 2 gyroscope sensors to build a Deep Learning classifier to recognise 5 different strength exercises, as well as a null class. The strength exercises tested in this research are as followed: Bench press, bent row, deadlift, lateral rises and overhead press. The null class contains recordings of daily activities, such as sitting or walking around the house. The model used in this paper consists on the creation of consecutive overlapping fixed length sliding windows for each exercise, which are processed separately and act as the input for a Deep Convolutional Neural Network. In this study we compare different sliding windows lengths and overlap percentages (step sizes) to obtain the optimal window length and overlap percentage combination. Furthermore, we explore the accuracy results between 1D and 2D Convolutional Neural Networks. Cross validation is also used to check the overall accuracy of the classifiers, where the database used in this paper contains 5 exercises performed by 3 different users and a null class. Overall the models were found to perform accurately for window’s with length of 0.5 seconds or greater and provided a solid foundation to move forward in the creation of a more robust fully integrated model that can recognize a wider variety of exercises.

    Food Allergy in Hospital from the Patient Perspective: taking a Mixed Methods approach to understand Foodservice Management2018Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Foodservice is integral to safe, adequate and satisfactory food allergy management in the hospital setting. To date, research focused on objective measures of energy and protein provision, implementation and evaluation of food allergy guidelines and assessment of process failures leading to allergen exposure. There is a lack of focus on taking a person-centred approach to understanding the barriers and enablers to optimal food allergy management.

    A mixed methods phenomenological approach was espoused at a tertiary acute care hospital in Melbourne, Victoria. Data collection techniques included 24-hr diet recall, foodservice satisfaction questionnaires and semi-structured qualitative interviews, all delivered by an Accredited Dietitian. Statistical and thematic analysis was conducted, followed by convergence of the results from each phase of the study.

    Mean energy intake indicated 64% of requirements and 81% of protein requirements were met; which included external food intake to supplement the hospital diet for around half of the patients. Most patients rated their overall food service satisfaction as ‘Good’, with food quality being the lowest rated foodservice dimension. Addressing sensory, variety and communications aspects of foodservice were focus areas identified by the study patients. These included improving bland flavours and plain appearance, restricted menu choices and automated allergen interface between systems.

    With a person-centred care focus, the study identified new findings on the views and attitudes of patients with a food allergy on foodservice management in hospital. Within the Food and Meal Science field, the study may be seen as an initial exploratory enquiry for future research on food allergy.

    Mixture effects of 3 mechanistically different steroidogenic disruptors (prochloraz, genistein, and ketoconazole) in the H295R cell assay2015In: International journal of toxicology, ISSN 1091-5818, E-ISSN 1092-874X, Vol. 34, no 6, p. 534-542Article in journal (Refereed)
    Abstract [en]

    Mixture effects of 3 model endocrine disruptors, prochloraz, ketoconazole, and genistein, on steroidogenesis were tested in the adrenocortical H295R cell line. Seven key steroid hormones (pregnenolone, progesterone, dehydroepiandrosterone, androstenedione, testosterone, estrone, and 17β-estradiol) were analyzed using gas chromatography and tandem mass spectrometry (GC-MS/MS) to investigate the effects throughout the steroidogenic pathway. Current modeling approaches often rely on models assuming compounds acting independently and that the individual effects in some way can be summarized to predict a mixture effect. In H295R cells with an intact steroidogenic pathway, such assumptions may not be feasible. The purpose of this study was therefore to evaluate whether effects of a mixture with differing modes of action followed or deviated from additivity (concentration addition) and whether the H295R cell line was suitable for evaluating mixture toxicity of endocrine disruptors with different modes of action. The compounds were chosen because they interfere with steroidogenesis in different ways. They all individually decrease the concentrations of the main sex steroids downstream but exert different effects upstream in the steroidogenic pathway. Throughout the study, we observed lowest observed effect concentrations of mixtures at levels 2 to 10 times higher than the predicted EC50, strongly indicating antagonistic effects. The results demonstrate that chemical analysis combined with the H295R cell assay is a useful tool also for studying how mixtures of endocrine disruptors with differing modes of action interfere with the steroidogenic pathway and that existing models like concentration addition are insufficient in such cases. Furthermore, for end points where compounds exert opposite effects, no relevant models are available.

    Detection of plasmid families carrying ESBL genes in clinical and environmental E. coli and K. pneumoniae isolates2019Independent thesis Basic level (professional degree), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Extended Spectrum β-Lactamases (ESBLs) are produced by the Enterobacteriaceae bacterial family, mainly by E. coli and K. pneumoniae. As these species are some of the main causes of urinary tract infections and sepsis, ESBL-production is of major concern.

    Occurrence of ESBLs also gives rise to concern as it is increasing epidemically. This because the genes coding for ESBLs (i.e. bla-genes) are located on plasmids replicating and spreading the replicated copies independently. Plasmids replicate by replicons. Plasmids with the same replicon variant are grouped into the same plasmid family.

    The aim of this study was to detect plasmid families carrying bla-genes in E. coli and K. pneumoniae from clinical (n = 6) and environmental water (n = 22) isolates. Plasmid family prevalence was examined. Association between plasmid families and bla-genes was also examined.

    Plasmid families were detected by a PBRT kit (PCR Based Replicon Typing), a multiplex PCR kit that detected 30 replicons, whereof 27 replicons representing the 27 plasmid families in Enterobacteriaceae, and three novel replicons.

    The IncF plasmid family was the most prevalent for both species in both clinical and environmental isolates. IncF seemed to be prevalent for all examined ESBLs, but it was difficult to associate one bla-gene with one plasmid family as most isolates carried several bla-genes and several plasmid families.

    Influence of color, shape and damages on consumer preferences and perceived sensory attributes on sub-optimal apples2018Conference paper (Other academic)
    Abstract [en]

    Sustainable food production and consumption are key elements today. About one third of food produced for human consumption is wasted. Consumers are responsible for the largest amount of food waste throughout the supply chain; part of this is indirect by e.g. discarding food products already in the store. The unwillingness to purchase and consume sub-optimal food products is thought to be an important cause of food waste; however, the reasons behind it are still insufficiently studied. Our research addresses the question of how combinations of color, shape and damage of apples influence consumer preferences and perceived sensory attributes.

    Based on a cubic design of visual appearance (color (red-to-green); shape (normal-to-odd); damage (none-to-damage) with a total of eight combinations ranging from optimal to suboptimal in all three dimensions, a total of 130 participants (68% women and 32% men), participated in a laboratory study where an image for each apple type from the design was presented in a blind tasting session (peeled and sliced apples). Sensory perception was evaluated by thirteen flavor and texture attributes on a 7-point scale. Liking was evaluated on a 7-point hedonic scale.

    The results showed a significant difference between the optimal apple and apples with shape and damage imperfections. Further, the optimal apple was perceived sweeter, crispier and less bitter than all other apples. The optimal apple had higher liking score, significantly different from the apples which all had a sub-optimal shape. This means that an odd shape had a negative effect on liking. A linear regression analysis showed that odd shaped apples were perceived as mainly earthy and bitter. Hence, visual sub-optimality, even presented to consumers in images, have an effect on how an apple is perceived and liked where an odd shape has larger negative impact than color and damage.

    Sustainable fruit consumption: the influence of color, shape and damage on consumer sensory perception and liking of different apples2019In: Sustainability, ISSN 2071-1050, E-ISSN 2071-1050, Vol. 11, no 4626, p. 1-9, article id su11174626Article in journal (Refereed)
    Abstract [en]

    Sustainable food production and consumption are currently key issues. About one third of food produced for human consumption is wasted. In developed countries, consumers are responsible for the largest amount of food waste throughout the supply chain. The unwillingness to purchase and consume suboptimal food products is an important cause of food waste, however, the reasons behind this are still insufficiently studied. Our research addresses the question of how combinations of color, shape and damage of apples influence consumer liking and perceived sensory attributes. In a laboratory study based on factorial design of visual appearance (color, shape and damage varied from optimal to suboptimal) a total of 130 consumers evaluated sensory perception of flavor and texture attributes in apple samples. Liking was also evaluated. The results showed a significant difference in liking between an optimal apple and all apple categories with at least two out of three suboptimal properties. Further, it was a clear trend that the optimal apple was perceived as sweeter, crispier, less bitter, and less earthy than all the other apples by the participating consumers, however, the results were not statistically significant. A suboptimal appearance, therefore, had a negative effect on both perception and liking.

    Children's pictures of a good and desirable meal in kindergarten: a participatory visual approach2019In: Children & society, ISSN 0951-0605, E-ISSN 1099-0860, Vol. 33, no 5, p. 471-487Article in journal (Refereed)
    Abstract [en]

    In kindergarten, meals are framed and regulated by the adults and ideas within the institution. However, by inviting children to visualise their ideas, they can be included when trying to understand as well as develop the meals. The purpose was to explore children's pictures of good and desirable meals in kindergarten by using a visual, participatory approach together with children four to six years. The children related to various aspects of the meal, emphasising the importance of food, table artefacts and context, defined as platescape, tablescape and roomscape. The result further highlighted the complexity of listening to the plurality of children's voices.

    Sjuk mat?: styrande faktorer och utmaningar för sjukhusmåltidens kvalitet ur kostchefers perspektiv2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Debatten om sjukhusmåltidens kvalitet är aktuell och kritiseras idag i press och sociala medier. Bloggen Food Pharmacy (2018) har startat uppropet #Sjukmat, där privatpersoner uppmanas att dela med sig av bilder och berättelser om den mat de blivit serverade i sjukhusmiljö, för att belysa problemet. Genom att intervjua kostchefer gällande deras uppfattning om sjukhusmatens kvalitet och de bakomliggande faktorer som inverkar på kvaliteten, hoppas författarna kunna visa en mer komplex bild av sjukhusmaten än den som presenteras idag.

       Syftet är att undersöka kostchefers uppfattningar gällande vilka faktorer som styr kvaliteten på sjukhusmåltiden, samt att studera vilka utmaningar som kan påverka sjukhusmåltidens kvalitet.

       En deskriptiv studiedesign användes. Sammanlagt deltog 16 kostchefer i Sverige från 12 olika län i telefonintervjuer, vilka transkriberades och tolkades med hjälp av en tematisk analys.

       Resultatet visar att flera faktorer samverkar för god måltidskvalitet på sjukhus; vilka råvaror som används, hur maten hanteras, patienters möjlighet att välja vad och när de ska äta, vilka resurser som finns tillgängliga för sjukhusen samt kompetens och samarbete mellan vård- och kökspersonal. De främsta utmaningarna som lyfts är möjlighet att individanpassa måltidslösningar, större valfrihet för patienter, kunskap hos personal, samarbete och kommunikation med vården samt resurser i form av tid och pengar.

       Slutsatsen är att arbetet bakom sjukhusmåltiden är komplext. Flera faktorer är avgörande för om maten äts upp och uppskattas av patienterna, och dessa faktorer samverkar i mycket stor utsträckning. Dock framlägger dessa utmaningar konkreta förbättringsområden. De engagerade kostcheferna vill visa att problem är till för att lösas, och att #sjukmat kan bli #friskmat.

    Long-distance and local movements of greylag geese in present-day agricultural landscapes2018In: 18th Conference of Goose Specialist Group: Conference Abstracts / [ed] Rasa Morkune, Modestas Bruzas, Julius Morkunas, Marine Institute of Klaipeda University , 2018, p. 77-Conference paper (Refereed)
    Abstract [en]

    Recent changes in environmental conditions together with increasing goose populations have completely changed the ballgame for geese in Europe. To better understand their current distribution and foraging patterns, this project will explore how geese utilize the agricultural landscape, with focus on their movements, field selection and foraging patterns. We fitted 199 Greylag geese with neck-collars and 64 with GPS transmitters at 5 locations in Sweden. The tagged geese will be used for studying movement patterns at a field-tofield level. However, the GPS transmitters also deliver data that can be used together with re-sightnings of neck-collared geese to unravel large-scale movement patterns of the Swedish Greylag goose population. Preliminary results from GPS positions received June--November 2017 indicate a varation in migration patterns and wintering grounds, depending on the origin of the geese. Geese breeding and molting in the southern parts of Sweden seem to migrate shorter distances, and have spent most of their time during the autumn months in Denmark, or in the southernmost parts of Sweden, while the geese marked farther north migrated earlier and moved longer distances, with the majority spending the autumn in Germany and the Netherlands.

    Jämföra Protrombinkomplex International Normalized Ratio, PK (INR)- värdet, för plasma och helblod för kapillärt tagna PK-prover på instrumentet STA R Max (Stago)2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Warfarin is a drug used to prevent high-risk patients such as those with atrial fibrillation from thromboembolisms. This effect is achieved by suppressing vitamin-K dependent factors VII, X and prothrombin and therefore decreasing the bloods ability to clot. Finding the right dosage of the drug for warfarin treated patients has proven difficult, as it demands regular blood draws to monitor their prothrombin complex level, which is affected by dietary and living habits. The most common way to measure prothrombin complex levels is by using venous plasma but it is also possible to use capillary plasma. Whole blood can be used for mechanical methods, which don’t use optical detection. The benefit is that whole blood doesn’t require centrifugation. The aim of this study was to investigate if there was a significant difference (p≤0,05) between using whole blood and plasma which is the existing method for capillary sample and also if there is any differences between the stability of these samples. Double samples from 30 warfarin treated patients and 5 non-treated persons were taken. One of the samples were centrifuged and analyzed on plasma and the other analyzed on whole blood. The results showed that there was a significant difference (p≤0,05) between the methods. Bland-Altman plot comparison showed that 95 % of the whole blood samples would not be higher than 0,25 INR and lower than 0,14 INR. This has low clinical impact. The samples were stored at room temperature for up to 24 hours and reanalyzed. No changes over 10 % in INR values were observed. This study showed that even though there is a significant difference, it is possible to replace the existing method which using plasma with the whole blood instead.

    Etableringen av Ebbjörnarp: En paleoekologisk studie av torpetablering under tidig medeltid på Göingeåsen, Skåne2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    När en bebyggelse etablerades i ett område är svårt att läsa av de människoskapade landskapselementen. Dock kan ortnamnet ge en indikation om under vilken tidsperiod det kan ha uppstått bebyggelse. Perioden då ortnamn med efterledet -torp blir vanligt är också en tid av omfattande samhällsförändringar. Syftet med denna studie var att med paleoekologisk metodik datera när ett bebyggelsenamn med suffixet -torp etablerades vid en specifik lokal på Linderöds, Nävlinge- eller Göingeåsen. Med GIS-analys och fältarbete kunde en lämplig undersökningslokal hittas och två torvkärnor borras upp för vidare pollenanalys. Lagerföljden kunde genom 14C-metoden dateras till 727 e.Kr. ± 50 år på 96,5 centimeters djup. Med pollendiagrammet gjordes tolkningen att Ebbjörnarp etablerades under andra hälften av 1100-talet. Detta grundar sig på en uppgång av kolfragment som föregicks av en lång period med låg och jämn nivå. Etableringen skedde då fler trälar kom att friges. Om det rörde sig om en träl för Ebbjörnarps del låter vi vara osagt då det även kunde vara en vanlig bonde som tog chansen till ett arrende. Landskapet tiden före Ebbjörnarp var dels ett öppnare kulturlandskap med tydlig mänsklig närvaro, och dels senare ett mer beskogat landskap med lägre aktivitet.

    How about a vegan dessert?: men and women's attitudes towards vegan desserts, and how the appearance of vegan desserts affects the experience2018Independent thesis Advanced level (degree of Master (Two Years)), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Background: Women prefer to eat plant-based food more frequently than men. Previous studies show that there is a difference in what we eat depending on which gender we belong to. The experience of food can be influenced by various aspects such as colour, shape, serving, and food information.

    Objectives: The purpose of the study was to investigate if there were any differences between men and women's attitudes towards vegan desserts. Moreover, four vegan desserts were developed using creative design and molecular gastronomy, to investigate how the colour and shape of vegan desserts affects the experience of taste, flavour and texture.

    Material and methods: To answer the research question, two focus group interviews were conducted. Moreover, a creative design containing an online cross-sectional survey was performed to develop four vegan desserts using molecular gastronomy. The desserts had the same ingredients in equal quantities, but they differed in colour and shape.These desserts were subsequently tested in a sensory evaluation.

    Results: The results show that there is a difference between men and women regarding attitudes towards a vegan dessert. Women are more positive and curious, while men are more sceptical whether a vegan dessert tastesgood. There was sometimes a significant difference in taste, but never in flavour and texture.

    Conclusions: There are differences in men and women's attitudes towards vegan desserts, where women are more positive than men. Shape may affect the experience of taste, but not of flavour and texture in this study.

    Cultural differences in insect acceptance: a comparison between students on Sweden and Thailand2019In: Food and Society Proceedings / [ed] CardiffMet, Cardiff: CardiffMet , 2019, p. 139-144Conference paper (Refereed)
    Abstract [en]

    Insects is already part of the diet in many regions of the world, and in parts of Asia, Africa, Mexico and Southern America the eating of insects is part of a long tradition and cultural heritage3 . An example of a country where the consumption of insects is steadily increasing is Thailand4 .There were some cultural differences between Swedish and Thai students in regard to their disposition to react with disgust to certain food-related stimuli as measured by the Food Disgust Scale. Swedish students were more concerned than those from Thailand about putting animal cartilage into the mouth and by eating with dirty silverware in a restaurant. Thai students where on the other hand more disgusted than Swedes by eating hard cheese from which mold was cut off or to eat apple slices that has turned brown when exposed to air.

    Food and meal science: creating a learning environment that promotes creativity2018Conference paper (Other academic)
    Abstract [en]

    Food and Meal Science is an interdisciplinary research and education field at Kristianstad University with a vision to create a sustainable and healthy society. The field includes the areas “Nutrition and Health”, “Food Science” and “Food Culture and Communication” and is based on science, craftsmanship and creativity. Developing the creative elements of our educations is currently a strategic focus. Psychology literature points to the importance of self-efficacy, i.e. the belief in one’s own ability, for successfully achieving creative outcomes (Tierney and Farmer, 2002). Research in the intersection between education and psychology have reveled effective methods for supporting the development of creative self-efficacy, e.g. allowing students to experience mastery and working with verbally ensuring students of their creative abilities (Mathisen & Bronnik, 2009). It could be hypothesized that teaching inspired by these principles will markedly increase creative self-efficacy and hence creativity among our students as well.

    With the overall goal to develop shared knowledge and to improve contextual factors to create a learning environment that promotes creativity a questionnaire for monitoring creative self-efficacy levels among students over time has been developed through adaptation of Tierney and Farmers (2002) method in order to measure how our teaching methods influence creative self-efficay. The questionnaire has been presented to approximately 40 students in the study programs connected to Food- and Meal Science.

    The results from the questionnaire as well as course evaluations will be used as a starting point to improve contextual factors and to create a learning environment that support creativity.

    Sensory characteristics of meat from steers of various breeds and rearing intensities2019Conference paper (Refereed)
    Abstract [en]

    The most common category of young cattle slaughtered for beef in Sweden is bulls of dairy breed, most often reared indoors. There is however a potential in raising steers (castrated bulls) for slaughter on semi-natural pasture, which may have an impact on sensory properties of the meat. Furthermore, weight gain and carcass characteristics may be improved by crossing dairy breeds with specialised beef breeds. In combination with the new technique of sex-sorted dairy semen, beef breed semen can be used to the less superior cows in the herd without jeopardizing an adequate number of replacement heifers from the superior cows. The aim of the study was to investigate whether there are any differences in sensory meat quality between cross bred and purebred cattle and between two rearing intensities including semi-natural pasture. Sensory properties were evaluated by a trained, analytical panel consisting of six assessors by the use of descriptive analysis. The intensity of iron, acidic, tallow, milky and barny odour as well as metallic, barny and gamey flavour and basic tastes were assessed in triplicate along with attributes describing the appearance and texture of the meat. Differences were mainly found in appearance and texture attributes, but also gamey flavour and the intensity of umami were affected by the rearing and breeding regimes. The meat quality results from this study will be combined with results from other disciplines such as animal science, business administration and environmental science. It is important to be able to demonstrate various possible added values that comes from pasture-based beef production systems under Swedish conditions.

    The effect of emulsion intensity on selected sensory and instrumental texture properties of full-fat mayonnaise2018In: Foods, E-ISSN 2304-8158, Vol. 7, no 1Article in journal (Refereed)
    Abstract [en]

    Varying processing conditions can strongly affect the microstructure of mayonnaise, opening up new applications for the creation of products tailored to meet different consumer preferences. The aim of the study was to evaluate the effect of emulsification intensity on sensory and instrumental characteristics of full-fat mayonnaise. Mayonnaise, based on a standard recipe, was processed at low and high emulsification intensities, with selected sensory and instrumental properties then evaluated using an analytical panel and a back extrusion method. The evaluation also included a commercial reference mayonnaise. The overall effects of a higher emulsification intensity on the sensory and instrumental characteristics of full-fat mayonnaise were limited. However, texture was affected, with a more intense emulsification resulting in a firmer mayonnaise according to both back extrusion data and the analytical sensory panel. Appearance, taste and flavor attributes were not affected by processing.

    Determination of thirteen antibiotics in drug products: a new LC-MS/MS tool for screening drug product quality2014In: Analytical Methods, ISSN 1759-9660, E-ISSN 1759-9679, Vol. 6, p. 5847-5855Article in journal (Refereed)
    Abstract [en]

    Poor quality antibiotic medicines in circulation in Sub-Saharan Africa continue to be a burden. Pharmaceutical trade in substandard and counterfeit medicines is on the rise. The chemical quality of antibiotics dispensed in health facilities and recognised drug outlets in Ghana, when compromised, could be a major drawback to efforts made in fighting antibiotic resistance globally. To improve on antibiotic drug quality monitoring, a liquid chromatography-tandem mass spectrometry (LC-MS/MS) methodology, which is capable of quantifying thirteen antibiotics in drug products, was developed and validated in present work. The methodology was applied to various drug products including tablets, capsules, suspensions, syrups, intravenous and injection solutions as well as ear and eye droplets used as essential medicines in a Sub-Saharan country, Ghana.

    Nordic student teachers’ views on the most effcient teaching and learning methods for species and species identification2019In: Sustainability, ISSN 2071-1050, E-ISSN 2071-1050Article in journal (Refereed)
    Abstract [en]

    Teachers need knowledge of species and species identification skills for teaching thestructure and function of ecosystems, and the principles of biodiversity and its role in sustainability.The aim of this study is to analyze Nordic student teachers’ views on the most ecient methodsand strategies to teach and learn species and species identification, and to find some trends abouthow well their views are reflected in a species identification test. Student teachers in Finland,Norway, and Sweden (N = 426) answered a questionnaire consisting of fixed and open-endedquestions, and a species identification test. An analysis of variance, Chi-Square, and t-test were usedfor quantitative data and an inductive content analysis for qualitative data. Results showed thatoutdoor teaching and learning methods are more ecient than indoor methods. The majority ofstudent teachers considered outdoor experiential learning with living organisms as the most ecientteaching and learning method. Student teachers who highlighted outdoor experiential learning andoutdoor project work as their most ecient methods received significantly better results in the speciesidentification test than the others. Field trips and fieldwork were emphasized as the most importantsources in schools and universities, while the Internet was the most important source among media.The student teachers underlined teachers’ expertise in the form of in-depth understanding of subjectsand supervising skills for ecient teaching both outdoors and indoors. Therefore, teaching andlearning of species and species identification as the practical part of biodiversity and sustainabilityeducation is emphasized as an integral part of teacher education programs.

    Cardiovascular risk factors in relation to dietary patterns in 50-year-old men and women: a feasibility study of a short FFQ2019In: Public Health Nutrition, ISSN 1368-9800, E-ISSN 1475-2727, Vol. 22, no 4, p. 645-653Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE: We aimed to assess the feasibility of a simple new fifteen-item FFQ as a tool for screening risk of poor dietary patterns in a healthy middle-aged population and to investigate how the results of the FFQ correlated with cardiovascular risk factors and socio-economic factors.

    DESIGN: A randomized population-based cross-sectional study. Metabolic measurements for cardiovascular risk factors and information about lifestyle were collected. A fifteen-item FFQ was created to obtain information about dietary patterns. From the FFQ, a healthy eating index was created with three dietary groups: good, average and poor. Multivariate logistic regression was used to assess relationships between dietary patterns and cardiovascular risk factors.

    SETTING: Sweden.

    SUBJECTS: Men and women aged 50 years and living in Gothenburg, Sweden.

    RESULTS: In total, 521 middle-aged adults (257 men, 264 women) were examined. With good dietary pattern as the reference, there was a gradient association of having obesity, hypertension and high serum TAG in those with average and poor dietary patterns. After adjustment for education and lifestyle factors, individuals with a poor dietary pattern still had significantly higher risk (OR; 95 % CI) of obesity (2·33; 1·10, 4·94), hypertension (2·73; 1·44, 5·20) and high serum TAG (2·62; 1·33, 5·14) compared with those with a good dietary pattern.

    CONCLUSIONS: Baseline data collected by a short FFQ can predict cardiovascular risk factors in middle-aged Swedish men and women. The FFQ could be a useful tool in health-care settings, when screening for risk of poor dietary patterns.

    Det generella biotopskyddet av alléer: en analys av Länsstyrelsers dispensbeslut2018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    Det generella biotopskyddet i Sverige omfattar lättidentifierbara områden som finns över hela landet, där ingår bland annat alléer. Alléer är enligt miljöbalken lövträd planterade i en enkel eller dubbel rad som består av minst fem träd längs en väg eller det som tidigare utgjort en väg eller i ett i övrigt öppet landskap. Träden ska till övervägande del utgöras av vuxna träd. Skyddet innebär att man inte får bedriva en verksamhet eller vidta en åtgärd som kan skada naturmiljön. Om det finns särskilda skäl, får dispens från förbudet ges i det enskilda fallet. Det som anses vara ett särskilt skäl beskrivs i naturvårdsverket vägledning. Denna kandidatuppsats syfte är att undersöka hur länsstyrelser i Sverige behandlar beslut om dispens från det generella biotopskyddet av alléer, genom att analysera hur natur- och kulturvärdet behandlas i besluten samt att undersöka vad det är som gör att dispenser blir beviljade respektive avslagna. För att kunna analysera besluten strukturerat har en analysmall använts. Resultatet visar att naturvärdet berörs i alla de analyserade besluten. Beslut från Länsstyrelsen Skåne och Dalarna berör kulturmiljövärdet mest. Alla besluten som är beviljade dispens är motiverade med ett särskilt skäl.   Beslut som får avslag blir ofta nekade dispens när ansökan innehåller termer och ord som berör alléns estetiska värde och när det saknas särskilt skäl.  Under rubriken diskussion lyfts problematiken med att endast skydda alléernas naturvärde i ett landskap fyllt med kultur, men också handläggarens tolkningsutrymme av lagstiftningen.

    Landskapets förändring i östra Blekinges skärgårdsbygd: en studie i markanvändningens och befolkningens förändring på Östra Hästholmen och Utlängan, 1700 - 20162018Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [sv]

    På de platser där markens kapacitet för odling, slåtter eller bete är låg har människan tvingats se sig om efter komplement till markens ringa avkastning. För öborna på Östra Hästholmen och Utlängan i Karlskronas östra skärgård kompletterades detta med husbehovsfiske i Östersjön. Här försörjde man sig som binäringsfiskare eller som lots i kronans tjänst.Det här är en studie av förändringar i befolkning, markanvändning, mantalsfördelning, binäringsfisket och lotsyrket på Östra Hästholmen och Utlängan mellan 1700 – 2016. Vidare tas örlogsbasens militära närvaro i beaktning. Utifrån studier av kartmaterial, mantalslängder och folkräkningar har information kring dessa förändringar jämförts mot varandra.Resultatet visar att befolkningsantalet och markanvändningen troligtvis inte påverkat varandra i det långa loppet. Snarare är det möjligheten till fisket och arbetet som lots som har bidragit till öarnas befolkningskurva och markanvändning. Östra Hästholmen verkar ha varit av störst betydelse för befolkningen under 1700- och 1800-talen på grund av dess lotshemman där man verkade som ”kronolots” medan Utlängan visar sig ha varit av större betydelse i äldre tider och då för sjömän från olika delar av Europa.

    Investigation of Event-Prediction in Time-Series Data: How to organize and process time-series data for event prediction?2019Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    The thesis determines the type of deep learning algorithms to compare for a particular dataset that contains time-series data. The research method includes study of multiple literatures and conduction of 12 tests. It deals with the organization and processing of the data so as to prepare the data for prediction of an event in the time-series. It also includes the explanation of the algorithms selected. Similarly, it provides a detailed description of the steps taken for classification and prediction of the event. It includes the conduction of multiple tests for varied timeframe in order to compare which algorithm provides better results in different timeframes. The comparison between the selected two deep learning algorithms identified that for shorter timeframes Convolutional Neural Networks performs better and for longer timeframes Recurrent Neural Networks has higher accuracy in the provided dataset. Furthermore, it discusses possible improvements that can be made to the experiments and the research as a whole.

    Recovering Whooper Swans do not cause a decline in Eurasian Wigeon via their grazing impact on habitat2018In: Journal of Ornithology = Journal fur Ornithologie, ISSN 0021-8375, E-ISSN 1439-0361, Vol. 159, p. 447-455Article in journal (Refereed)
    Abstract [en]

    The Whooper Swan (Cygnus cygnus) is a good example of successful conservation, with rapidly growing numbers in Fennoscandia in recent decades. To the contrary, Eurasian Wigeon (Mareca penelope) shows a strong negative trend in breeding numbers, which raises conservation concerns. Previous research suggests a causal link between recent population trajectories of the two species. Both preferentially breed on wetlands with abundant horsetail (Equisetum spp.), a plant providing food for Whooper Swan and crucial feeding microhabitat for Eurasian Wigeon broods. We here test predictions based on the hypothesis that grazing on Equisetum by Whooper Swan reduces breeding habitat or breeding habitat quality for Eurasian Wigeon. We use data from 60 lakes in which waterfowl were counted in 1990–1991 and 2016, and Equisetum was mapped in 1990–1991 and 2013–2014. Lakes colonized by Whooper Swan typically had more abundant Equisetum vegetation in the past than lakes not colonized. Lake-specific decrease of Equisetum was not associated with colonization by Whooper Swan. The number of lakes occupied by Eurasian Wigeon decreased, but the decrease was not stronger on lakes colonized by Whooper Swan than on those that were not. Contrary to our prediction, current Eurasian Wigeon abundance was positively associated with Whooper Swan abundance. Moreover, Eurasian Wigeon did not decrease more on lakes from which Equisetum disappeared than on lakes in which there was still Equisetum left. This study does not support the idea that Whooper Swan affects Eurasian Wigeon negatively by grazing on Equisetum.

    Changes in species richness and composition of boreal waterbird communities: a comparison between two time periods 25 years apart2019In: Scientific Reports, ISSN 2045-2322, E-ISSN 2045-2322, Vol. 9, no 1Article in journal (Refereed)
    Abstract [en]

    Global measures of biodiversity indicate consistent decline, but trends reported for local communitiesare more varied. Therefore, we need better understanding of mechanisms that drive changes in diversity of local communities and of differences in temporal trends between components of local diversity, such as species richness and species turnover rate. Freshwater ecosystems are vulnerable to multiple stressors, and severe impacts on their biodiversity have been documented. We studied species richness and composition of local boreal waterbird communities in 1990/1991 and 2016 at 58 lakes distributed over six regions in Finland and Sweden. The study lakes represented not only local trophic gradients but also a latitudinal gradient in the boreal biome. While species richness tended to be lower in 2016 than in 1990/1991, species turnover was relatively high. Within foraging guilds, local species richness of diving ducks and surface feeding waterbirds decreased, whereas that of large herbivores increased. The number of species gained in local communities was higher in lakes with rich vegetation than in lakes with sparse vegetation. Conservation of boreal freshwater ecosystems would benefit from recognizing  hat large-scale environmental changes can affect local diversity via processes operating atfiner scales.

    Biology and history in eastern Asian landscapes compared with Europe2012In: The 55th symposium of the international association for vegetation science: climate change and vegetation science / [ed] Eun Ju Lee, Hyesoon Kong, Kang-Hyun Cho, Yowhan Son, Jang-Geun Oh, Do-Soon Cho, Jong-Won Kim, Sun-Kee Hong, 2012Conference paper (Other academic)
    Abstract [en]

    This project is a continuation 0f Urban Emanuelsson's book "The rural landscapes of Europe - How man has shaped European nature" from 2009 which was written from a biological-historical perspective. In eastern Asia climate is roughly comparable with Europe, and both areas have long and independent land use traditions. Vegetation patterns can also be compared although differences are also pronounced and eastern Asia more species rich. Rice and millet/wheat production developed in both areas as well as societies relying on nomadic animal rearing. Human development has, however, been highly independent in the two areas, which makes comparisons interesting. In this project eastern Asia (roughly China north of Chang Jiang, Mongolia, SE Russia from Buryatia ta Primorye, Korea and Japan) and Europe (within its historical borders) will be compared.

    Some factors that have led to different landscape patterns in the two areas are:

    • Different attitudes towards grazing stock

    • Different attitudes towards forest

    • Different food cultures

    • Different routes and timing of cultural influence from other areas

    • Different kinds of religious conceptions about the landscape

    • Different kinds of major political movements during the past 100 years

    We work in a distinctly interdisciplinary way, and the interaction of environmental and social factors behind landscape changes is in focus. Archaeology and the geological and climate-related basis for the biodiversity are being addressed, followed by descriptions of cultural variation and different forms of land-use. Timing and reasons for the introduction of agriculture in different areas is of particular interest. Competition between grazing, agriculture, forest use and other land-use, is being described, particularly along ecological border zones, as well as the effects on the landscape by religious conceptions. How the biota has changed through time, often drastically so, is being described in relation to both human interference and climate and other changes. Historical influence of land use and the present day landscapes, also where these are apparently or allegedly "natural" is of particular concern. The current situation will be discussed, and weight given to how the landscape today can be used for recreation and tourism.

    Progress is made through field visits and literature studies. The end product will be a book with co-authorship of scholars within the region to be published within two years time.

    Man and Biosphere Health: en komplett akademisk miljö2018Collection (editor) (Other academic)
    Abstract [sv]

    Inom forskningsmiljön Man and Biospere Health, förkortat MABH (hkr.se/mabh), bedrivs forskning inom biologi, kemi, biomedicin och psykologi, men också mycket tvärvetenskaplig forskning, med fokus kring människans påverkan på ekosystem och dess effekter på biologiskt liv, mångfald och hälsa. Forskare inom MABH är också involverade i åtgärdsprogram och utveckling av nya tekniker och metoder för att kunna undersöka de negativa effekterna av människans aktiviteter. Forskningsmiljön MABH bildades 2009 med syfte att samla högskolan forskning inom bland annat ekologi, miljöteknik, kemi och biomedicin under ett paraply. Ambitionen var att utveckla tvärvetenskapliga projekt såväl inom som utanför gruppen.

    Forskningsanknuten grundutbildning: utbildningsanknuten forskning?2018In: Man and Biosphere Health: en komplett akademisk miljö / [ed] Ann-Sofi Rehnstam-Holm, Kristianstad: Högskolan Kristianstad , 2018, p. 8-15Chapter in book (Other academic)
    Abstract [sv]

    Begreppet forskningsanknuten utbildning kan definieras på ett flertal sätt. Idealt ska studenterna inom sin utbildning stöta på forskning genom att få kännedom om aktuell forskning och vara praktiskt involverade i forskningsprojekt. För att detta ska uppnås bör majoriteten av lärarna vara forskningsaktiva inom för utbildningen relevanta områden och att ett vetenskapligt förhållningssätt till kunskap förmedlar på bästa pedagogiska sätt också detta förankrat i forskning. I den här artikeln ger vi exempel på hur studenter har involverats i våra forskningsprojekt både på högskolan, på universitetssjukhuset i Lund och vid internationella universitet och forskningsstationer.

    Biogas final digestive byproduct applied to croplands as fertilizer contains high levels of steroid hormones2013In: Environmental Pollution, ISSN 0269-7491, E-ISSN 1873-6424, Vol. 180, p. 368-371Article in journal (Refereed)
    Abstract [en]

    In this study we evaluate and demonstrate the occurrence of nine natural and one synthetic steroid hormone, including estrogens, androgens and progestagens in biogas final digestate byproduct (digestion liquid) commonly used as an agricultural fertilizer. We investigated two biogas sites that utilize different anaerobic digestion technologies (mesophilic and thermophilic) from swine manure and other organic wastes. Individual hormone concentration levels were observed up to 1478 ng g−1 dry weight or 22.5 mg kg−1 N with estrone and progesterone reaching highest concentration levels. Evaluation of the potential environmental burden through the application in agriculture was also assessed on the basis of predicted environmental concentrations. This study indicates that the biogas digestion process does not completely remove steroid hormones from livestock manure and use of final digestate byproduct on croplands contributes to the environmental emission of hormones.
