    • In the era of the IoT revolution, applications are becoming ever more sophisticated and accompanied by diverse functional and non-functional requirements, including those related to computing resources and performance levels. Such requirements make the development and implementation of these applications complex and challenging. Computing models, such as cloud computing, can provide applications with on-demand computation and storage resources to meet their needs. Although cloud computing is a great enabler for IoT and endpoint devices, its limitations make it unsuitable to fulfill all design goals of novel applications and use cases. Instead of only relying on cloud computing, leveraging and integrating resources at different layers (like IoT, edge, and cloud) is necessary to form and utilize a computing continuum. The layers’ integration in the computing continuum offers a wide range of innovative services, but it introduces new challenges (e.g., monitoring performance and ensuring security) that need to be investigated. A better grasp and more profound understanding of the computing continuum can guide researchers and developers in tackling and overcoming such challenges. Thus, this paper provides a comprehensive and unified view of the computing continuum. The paper discusses computing models in general with a focus on cloud computing, the computing models that emerged beyond the cloud, and the communication technologies that enable computing in the continuum. In addition, two novel reference architectures are presented in this work: one for edge–cloud computing models and the other for edge–cloud communication technologies. We demonstrate real use cases from different application domains (like industry and science) to validate the proposed reference architectures, and we show how these use cases map onto the reference architectures. Finally, the paper highlights key points that express the authors’ vision about efficiently enabling and utilizing the computing continuum in the future.

    • Background: Is it possible to increase the value, meaningfulness, and relevance of a course experience by integrating it with the healthcare context? Students and teachers from a course on organization, learning and leadership sought to explore this possibility through a collaborative effort with nurses from an affiliated teaching hospital. Methods: Working as teachers, students created continuing nursing education (CNE) courses using the Adaptive Reflection process. The students and teachers then researched the experience in terms of: 1) content analysis of student self-reflections (discussion notes and logbooks) on the learning process, 2) a student self-assessed outcome achievement survey, and 3) perceived relevance of the CNE courses by the clinical nurse educators. Results: Thirteen nursing students created three CNE courses together with sixteen nurses. Each course consisted of multiple 20-minute long web-based modules with automatic formative feedback. In the process, students exceeded course outcome-levels, journeyed from chaos to confidence and experienced new ways of viewing the group and their own capabilities. Conclusions: The innovative design of the course moved the focus from student-centered learning to learning by contributing to health care. Working in a real world context, the content of the students' efforts and the skills they developed not only met course requirements, but were also aligned with the needs of the wards. This contribution was valued by the students and the RNs which enhanced students' feelings of self-confidence. Further research lies in testing the model in other contexts.

    • Background: Chronic inflammation plays an important role in several human cancers and may be involved in the etiology of prostate cancer. Toll-like receptors (TLRs) are important in the innate immune response to pathogens and in cross-talk between innate immunity and adaptive immunity. Our previous finding of an association of TLR4 gene sequence variants and prostate cancer risk provides evidence for a role of TLRs in prostate cancer. In this study, we investigated whether sequence variants in the TLR6-TLR1-TLR10 gene cluster, residing within a 54-kb region on 4p14, were associated with prostate cancer risk. Methods: We selected 32 single-nucleotide polymorphisms (SNPs) covering these three genes and genotyped these SNPs in 96 control subjects from the Cancer Prostate in Sweden (CAPS) population-based prostate cancer case-control study. Five distinct haplotype blocks were inferred at this region, and we identified 17 haplotype-tagging SNPs (htSNPs) that could uniquely describe < 95% of the haplotypes. These 17 htSNPs were then genotyped in the entire CAPS study population (1383 case subjects and 780 control subjects). Odds ratios of prostate cancer for the carriers of a variant allele versus those with the wild-type allele were estimated using unconditional logistic regression. Results: The allele frequencies of 11 of the 17 SNPs were statistically significantly different between case and control subjects (P = .04-.001), with odds ratios for variant allele carriers (homozygous or heterozygous) compared with wild-type allele carriers ranging from 1.20 (95% confidence interval [CI] = 1.00 to 1.43) to 1.38 (95% CI = 1.12 to 1.70). Phylogenetic tree analyses of common haplotypes identified a clade of two evolutionarily related haplotypes that are statistically significantly associated with prostate cancer risk. These two haplotypes contain all the risk alleles of these 11 associated SNPs. Conclusion: The observed multiple associated SNPs at the TLR6-TLR1-TLR10 gene cluster were dependent and suggest the presence of a founder prostate cancer risk variant on this haplotype background. The TLR6-TLR1-TLR10 gene cluster may play a role in prostate cancer risk, although further functional studies are needed to pinpoint the disease-associated variants in this gene cluster.

    • With the increasing incidence of prostate cancer, identifying common genetic variants that confer risk of the disease is important. Here we report such a variant on chromosome 8q24, a region initially identified through a study of Icelandic families. Allele -8 of the microsatellite DG8S737 was associated with prostate cancer in three case-control series of European ancestry from Iceland, Sweden and the US. The estimated odds ratio (OR) of the allele is 1.62 (P = 2.7 x 10(-11)). About 19% of affected men and 13% of the general population carry at least one copy, yielding a population attributable risk (PAR) of approximately 8%. The association was also replicated in an African American case-control group with a similar OR, in which 41% of affected individuals and 30% of the population are carriers. This leads to a greater estimated PAR (16%) that may contribute to higher incidence of prostate cancer in African American men than in men of European ancestry.

  • Preventing Falls and Malnutrition among Older Adults in Municipal Residential Care in Sweden : A Registry Study
  • 2021
  • Ingår i: Sage Open Nursing. - : SAGE Publications Inc.. - 2377-9608. ; 7
  • Tidskriftsartikel (refereegranskat)abstract
    • Introduction: Older adults in municipal residential care are among the most vulnerable and in need of most care. The prevalence of negative events, such as falls and malnutrition, is increased among these older adults. The need for strategies to prevent falls and malnutrition is emphasized in guidelines and systematic, individualized risk assessments are prerequisites for adequate interventions. Objectives: The overall purpose of this study was to investigate the assessed risks of, and risk factors for, falling and malnutrition and the correlations between these assessed risks among older women and men in residential care. Further, the purpose was to investigate the consistency between planned and performed interventions among women and men assessed as at risk. Methods: A cross-sectional registry study based on risk assessment data in the Swedish national quality registry, Senior Alert. Altogether, 5,919 older adults ≥65 in nursing homes and dementia care units in 19 municipalities in Sweden were included. Results: Of the older adults, 77% were at risk of falls, and 59% were at risk of malnutrition. The most prevalent risk factors for falls were previous falls and not being cognitively oriented; and for malnutrition were having mild or severe dementia or depression. A significant positive correlation between the risk of falling and the risk of malnutrition was found. Less than half of the planned interventions for falls and malnutrition were performed. Care staff’s least common interventions to prevent falls were balance, muscular function, and strength training, which contrasts with the recommendations; interventions to prevent malnutrition were only partially adhering to recommendations. Conclusions: This cross-sectional registry study points towards the importance of using an evidence-based approach, based on adherence to recommended guidelines, in the prevention of falling and malnutrition. Further, the implementation of clinical practice guidelines is needed, which requires educational training for care staff and supportive leadership.

  • Assistive robots in care : Expectations and pereceptions of older people
  • 2020
  • Ingår i: Aging between Participation and Simulation. - : De Gruyter Open. ; , s. 139-156
  • Bokkapitel (refereegranskat)abstract
    • This chapter analyzes older people’s expectations and perceptions about welfare technology and in particular about robots in elderly care. Assistive robots may serve as a means to prolonged autonomy in old age as well as support for nursing staff. Justified by a rapid change in the health care sector, the need to focus on user driven and not technology driven development of assistive robots must be emphasized to ensure an adequate and sustainable orientation process toward assistive robots. This study presents an inventory of the expectations and perceptions of older people regarding assistive robots, by conducting a qualitative approach with focus group discussions. Our findings reveal that seven themes in particular need to be addressed in order to improve older people’s perceptions of robot technology: (1) independence and safety, (2) physical and mental assistance, (3) communication and socialization, (4) relief to nursing staff, (5) individual’s right to decide, (6) data protection, and (7) liability. Additionally, the focus group interviews stress that dissemination of information on how robots can provide assistance may change older people’s attitudes towards technology

  • When do individuals choose care robots over a human caregiver? : Insights from a laboratory experiment on choices under uncertainty
  • 2023
  • Ingår i: Computers in Human Behavior Reports. - : Elsevier B.V.. - 2451-9588. ; 9
  • Tidskriftsartikel (refereegranskat)abstract
    • Demographic changes and a predicted shortage of nursing staff are progressively putting pressure on the healthcare system. Care robots may represent one part of a possible solution to this problem as they can assist care work. However, large parts of the population are reportedly skeptical about robotics in care, and field studies are difficult to conduct due to the low prevalence of real robotics in the field. Therefore, we follow an experimental approach pertaining to the question of individual decision-making. In this regard, we analyze the aspects that influence the individual's choice between a care robot and a human caregiver for assistance in their daily life. Our economic experiment is conducted in a virtual laboratory to examine specifically how quality uncertainty of care affects individual's decisions for and against robotic care. In the experiment, 162 participants fully completed the experiment in which they were asked to repeatedly choose between a human caregiver and a care robot. Our results reveal that, overall, the care robot is chosen more often than a human caregiver. At the same time, the quality uncertainty of care linked to a human caregiver barely affected the choice of participants. On the other hand, a participant's health status and their attitude toward direct interactions with care robots did partially affect their choice. Additionally, we explored causes for indecisiveness and its effect on the choice. Here, we found indecisive participants tending to choose a human caregiver more often.
