    Att motverka dehydrering hos äldre i teori och praktik2015Independent thesis Basic level (degree of Bachelor), 180 HE creditsStudent thesis
    Abstract [en]

    Objective: To identify similarities and differences in methods and aids used to prevent dehydraton in the elderly as identified from the scientific literature and from interviews with caretakers.

    Method: Literature studies was performed through the University Library search service ”OneSearch” and further from references in key papers. Three interviews were conducted on nursing assistants in two retirement homes and home care services, to offer some insight into the practical activities.

    Results : The following factors were identified as important in both literature and interviews: (1) knowledge of the elderly through documentation, (2) adapted approach when serving drinks after the elderly person's preferences and condition, (3) a homely environment with social interactions, (4) assessments of fluid intake, fluid balance and risk factors through attention, fluid registration and with the help of several other professional groups, and given the history of the elderly, (5) reminders for dementia and a accessibility of large amount of easily absorbed beverages consumed gradually during diarrhea and vomiting, (6) easy-to-use and specially designed drinking aids. For the following factors differences were obeserved between literature survey and interviews: (1) education for caregivers; limited to the investigated sites, (2) technical aids and swallowing therapy (dietary modifications, adapted head positions, swallowing training) in dysphagia; diet modification is used at the investigated sites (3) the importance of cup and jug colours; blue cups used in practice, no support in literature.

    Conclusions: Differences were found in terms of education and the use of swallowing therapy, assistive technology and infusions. Education, more frequent fluid registration and a complete swallowing therapy are improvement opportunites, some of them requires extra resources and/or clear guidelines. Acceptance of technical aids is not self-evident. Investigation of the effect of cup color and design that can encourage the elderly to drink could potentially be a way forward. The results of the interviews are not generalizable because they only aimed to give an insight into the practical activities. Most of the strategies that have been identified are "soft" in nature. It is difficult to get a clear picture of the efficiency of different methods. Methods that have been evaluated with good results in dysphagia and therefore offer potential to improve liquid intake, are swallowing therapy and stimulation of swallowing musculature.

    European wild boars and domestic pigs display different polymorphic patterns in the Toll-like receptor (TLR)1, TLR2, TLR6, and TLR10 genes.2010In: International Symposium on Animal Genomics for Animal Health Paris, France, 31 May – 2 June 2010: The AGAH 2010 Abstract Book, 2010, p. 35-Conference paper (Other academic)
    Abstract [en]

    The Toll-like receptors (TLR) are vitally important pattern recognition receptors linking innate and adaptive immunity. Several single nucleotide polymorphisms (SNP) in human TLR genes have been associated with disease. There are few studies on associations between polymorphisms in TLR genes and disease in pigs, but the TLR2/TLR6 heterodimer is activated by Mycoplasma hyopneumoniae, and the expression of TLR2, TLR4, and TLR9 is modulated in the presence of different Salmonella serovars. Porcine TLR1, TLR6, and TLR10 are located in a cluster on the p arm of chromosome 8, while TLR2 resides on the q arm. Previously, we identified quantitative trait loci (QTL) for immune-related traits on pig chromosome 8, close to the KIT gene and the microsatellite S0225, respectively. In order to explore polymorphism in some TLR genes in European wild boars and domestic pigs, TLR1, TLR2, and TLR6 were sequenced in 25 wild boars, representing three populations, and in 15 domestic pigs of Hampshire, Landrace, and Large White origin. Similarly, TLR10 was sequenced in 15 wild boars and 15 domestic pigs. In TLR1 and TLR2, more SNP were present in the domestic pigs than in the wild boars. In TLR6, SNP numbers were similar in both animal groups, but the level of heterozygosity was higher in the domestic pigs than in the wild boars. In TLR10, again, more SNP were present in the domestic pigs, and a higher number of nonsynonymous SNP were detected in TLR10 compared to the other genes. This may suggest redundancy for TLR10 in pigs.

    Escherichia coli and Salmonella in pigs2010In: Breeding for Disease Resistance in Farm Animals / [ed] RFA Axford, S Bishop, F Nicholas, JB Owen, Walllingford, UK: CABI Publishing, 2010, 3rd, p. 232-250Chapter in book (Other academic)
    Abstract [en]

    Diarrhoea due to bacterial infections is a problem mainly in the young growing animal, including the pig. Among the bacteria that cause diarrhoea in pigs are various strains of Escherichia coli and Salmonella. Considerable genetic variation in resistance/susceptibility has been found for both neonatal and post-weaning diarrhoea caused by E. coli carrying F4 fimbriae and post-weaning diarrhoea and oedema disease due to E. coli strains with F18 fimbriae. The loci for the receptors of both types of fimbriae have been mapped: the F4 receptor(s) to chromosome 13 (SSC13) and the F18 receptor to chromosome 6 (SSC6). Several candidate genes have been suggested for the F4 receptor, among them different mucine genes (MUC4, MUC13), and a very close association between a single-nucleotide polymorphism (SNP) in an alpha (1, 2) fucosyltransferase gene (FUT1) and the F18 receptor has been identified.Resistance to Salmonella infections in mice is associated with the antimicrobial activity of macrophages, and some studies have suggested that it is linked with polymorphism in the Nramp1 gene. The gene has been identified in several species including the pig, but data are so far lacking concerning association between polymorphism in the porcine gene and resistance-susceptibility to Salmonella infection. Using transcriptome profiles, several porcine genes that are differentially up or downregulated during Salmonella infection have been identified. Further studies of associations between polymorphisms in these genes and the outcome of Salmonella infection may facilitate the development of tools to identify carrier pigs, and lead towards identification of markers that can be used to select for resistant pigs.Breeding for increased disease resistance can be potentially performed in several ways; excluding susceptible breeding of animals after exposure, marker-assisted selection (MAS) based on closely linked loci or direct selection based on polymorphism in the causative gene. The rapid development in molecular genetics has provided dense genome maps and the tools to identify and study individual genes, both at the deoxyribonuclease acid (DNA) and the expression level. Overall use of genetic markers influencing disease traits is expected to increase significantly in the coming years. This number will grow as large-scale accurate disease phenotypes are collected in pedigreed populations. It is likely that many disease markers will contribute additively to the selection criteria and will be used as part of complex selection indices that will balance other economically significant traits.

    Refined candidate region specified by haplotype sharing for Escherichia coli F4ab/F4ac susceptibility alleles in pigs.2010In: Animal Genetics, ISSN 0268-9146, E-ISSN 1365-2052, Vol. 41, p. 21-25Article in journal (Refereed)
    Abstract [en]

    P>Infection of the small intestine by enterotoxigenic Escherichia coli F4ab/ac is a major welfare problem and financial burden for the pig industry. Natural resistance to this infection is inherited as a Mendelian recessive trait, and a polymorphism in the MUC4 gene segregating for susceptibility/resistance is presently used in a selection programme by the Danish pig breeding industry. To elucidate the genetic background involved in E. coli F4ab/ac susceptibility in pigs, a detailed haplotype map of the porcine candidate region was established. This region covers approximately 3.7 Mb. The material used for the study is a three generation family, where the founders are two Wild boars and eight Large White sows. All pigs have been phenotyped for susceptibility to F4ab/ac using an adhesion assay. Their haplotypes are known from segregation analysis using flanking markers. By a targeted approach, the candidate region was subjected to screening for polymorphisms, mainly focusing on intronic sequences. A total of 18 genes were partially sequenced, and polymorphisms were identified in GP5, CENTB2, APOD, PCYT1A, OSTalpha, ZDHHC19, TFRC, ACK1, MUC4, MUC20, KIAA0226, LRCH3 and MUC13. Overall, 227 polymorphisms were discovered in the founder generation. The analysis revealed a large haplotype block, spanning at least 1.5 Mb around MUC4, to be associated with F4ab/ac susceptibility.

    Hälsoundervisning: Elevers syn på hälsa inom ämnet Idrott och hälsa2009Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Fler unga människor än någonsin är idag överviktiga och stress och stressrelaterade symptom drabbar idag allt fler unga. Därför är det viktigt att unga människor får kunskaper om hur de på bästa sätt kan ta hand om sig själva.

     Syftet med detta arbete är att undersöka hur elever som läser gymnasiets kurs Idrott och hälsa A ser på den hälsoundervisning de får.

    Detta är relevant för alla som arbetar som idrott och hälsa lärare för att kunna hitta en jämkning mellan kursplan och elevernas tankar och förkunskaper.

     Genom intervjuer och fokusintervjuer kom jag fram till att eleverna vill lära sig mer om stress och hur man hanterar stress samt om kost. Eleverna tycker däremot att idrottsläraren inte är rätt person att lära ut kunskaper om tobak.
