- Exposure to vibrations from tools and machines used in construction work can induce damages to the human body. One of the most frequent symptoms is the hand-arm vibration syndrome commonly known as white fingers. The proportions of the international workforce exposed to vibrations are high and dominating sectors are construction, agriculture, forestry, and transport. Particularly exposed construction occupational groups include machine operators and drivers of vehicles. In 2005, the Swedish Work Environment Authority introduced a new guideline on the topic of preventing vibration exposure risks (AFS 2005:15) based on the European union 2002/44/EC directive on workers’ exposure to vibration. It includes raised demands on estimating vibration exposure, and clearly stated responsibilities and rights of employers and employees. However, in 2011 the Swedish Work Environment Authority’s inspections showed that many employers belonging to sectors such as building and construction, transport, and mining industry did not have any satisfactory proactive risk management work concerning vibration exposure. This paper reports on a pilot study performed in a large Swedish construction company with the aim to yield more knowledge about factors affecting the implementation of the guidelines and to suggest actions for improvement. A total of 31 construction workers and supervisors were interviewed at nine construction sites in southern Sweden. Interview results demonstrated a lack of knowledge in estimating vibration exposure; the incorporation of the Work Environment Authority’s directions had not been accomplished; driving forces for improving the proactive health and safety work and specifically vibration exposure management was weak on all organisational levels; important factors affecting the implementation of vibration exposure regulations are the psychosocial work environment at construction sites as well as company safety culture; a large proportion of the interviewed construction workers was judged to be at risk for developing vibration injuries if the exposure was not decreased; management, supervisory, and production levels need increased knowledge about vibration exposure and vibration injuries; and methods and tools for easy estimation of vibration exposure needs to be developed.

- The previous genome-wide scan in Scandinavian families supported earlier evidence for linkage of a region on chromosome 5 (5q31–33) to coeliac disease. This study deals with further genetic mapping of an 18 cM region, spanning from marker GAh18A (131.87 Mb) to D5S640 (149.96 Mb). Linkage and association analyses were performed in a two-step approach. First, seven microsatellites were added. Strong evidence for linkage was obtained with a Zlr score of 3.96, Pnc = 4 × 10−5 at marker D5S436. The strongest association was with a haplotype consisting of the markers D5S2033 and D5S2490 (Pnc < 0.001). In the second step, we added 17 microsatellites and 69 single nucleotide polymorphisms (SNPs) to the analysis. These markers were located close to or within candidate genes across the region of approximately 7 Mb beneath the linkage peak marked by D5S2017 and D5S812. A substantial increase of the linkage signal with a maximum Zlr score of 4.6 at marker rs1972644 (Pnc = 2 × 10−6) was obtained and several SNPs showed association. Seven SNPs that individually showed the strongest association were genotyped in a second independent family sample set (225 trios). In the trio family sample as well as in the multiplex family sample, the strongest association was found with SNPs within the region flanked by the associated microsatellites D5S2033 and D5S2490 at 5q32.

- Celiac disease (CD) is a gluten-induced enteropathy, which results from the interplay between environmental and genetic factors. There is a strong human leukocyte antigen (HLA) association with the disease, and HLA-DQ alleles represent a major genetic risk factor. In addition to HLA-DQ, non-HLA genes appear to be crucial for CD development. Chromosomal region 5q31–33 has demonstrated linkage with CD in several genome-wide studies, including in our Swedish/Norwegian cohort. In a European meta-analysis 5q31–33 was the only region that reached a genome-wide level of significance except for the HLA region. To identify the genetic variant(s) responsible for this linkage signal, we performed a comprehensive single nucleotide polymorphism (SNP) association screen in 97 Swedish/Norwegian multiplex families who demonstrate linkage to the region. We selected tag SNPs from a 16 Mb region representing the 95% confidence interval of the linkage peak. A total of 1404 SNPs were used for the association analysis. We identified several regions with SNPs demonstrating moderate single- or multipoint associations. However, the isolated association signals appeared insufficient to account for the linkage signal seen in our cohort. Collective effects of multiple risk genes within the region, incomplete genetic coverage or effects related to copy number variation are possible explanations for our findings.

- Growth-differentiation factor 15 (GDF-15) is expressed in low to moderate levels in most healthy tissues and increases in response to inflammation. GDF-15 is associated with cardiovascular dysfunction and over-expressed in the myocardium of patients with myocardial infarction (MI). However, little is known about the function of GDF-15 in cardiovascular disease, and the underlying regulatory network of GDF-15 is not known. To investigate a possible association between GDF-15 levels and DNA methylation, we performed a genome-wide DNA methylation study of white blood cells in a population-based study (N = 717). Significant loci where replicated in an independent cohort (N = 963). We also performed a gene ontology (GO) enrichment analysis. We identified and replicated 16 CpG-sites (false discovery rate [FDR] < 0.05), at 11 independent loci including MIR21. MIR21 encodes a microRNA (miR-21) that has previously been shown to be associated with the development of heart disease. Interestingly, GDF15 mRNA contains a binding site for miR-21. Four sites were also differentially methylated in blood from participants previously diagnosed with MI and 14 enriched GO terms (FDR < 0.05, enrichment > 2) were identified, including 'cardiac muscle cell differentiation'. This study shows that GDF-15 levels are associated with differences in DNA methylation in blood cells, and a subset of the loci are also differentially methylated in participants with MI. However, there might be interactions between GDF-15 levels and methylation in other tissues not addressed in this study. These results provide novel links between GDF-15 and cardiovascular disease.

- Lifestyle factors, such as food choices and exposure to chemicals, can alter DNA methylation and lead to changes in gene activity. Two such exposures with pharmacologically active components are coffee and tea consumption. Both coffee and tea has been suggested to play an important role in modulating disease-risk in humans by suppressing tumour progression, decreasing inflammation and influencing estrogen metabolism. These mechanisms may be mediated by changes in DNA methylation.To investigate if DNA methylation in blood is associated with coffee and tea consumption we performed a genome-wide DNA methylation study for coffee and tea consumption in four European cohorts (N = 3,096). DNA methylation was measured from whole blood at 421,695 CpG sites distributed throughout the genome and analysed in men and women both separately and together in each cohort. Meta-analyses of the results and additional regional-level analyses were performed.After adjusting for multiple testing, the meta-analysis revealed that two individual CpG-sites, mapping to DNAJC16 and TTC17, were differentially methylated in relation to tea consumption in women. No individual sites were associated in men or in the sex-combined analysis for tea or coffee. The regional analysis revealed that 28 regions were differentially methylated in relation to tea consumption in women. These regions contained genes known to interact with estradiol metabolism and cancer. No significant regions were found in the sex-combined and male-only analysis for either tea or coffee consumption.

Expert risk communication from an organisational context view
- 2023

Ingår i: ; , s. 65-65

Konferensbidrag (refereegranskat)abstract
- During recent years new threats have accentuated the role of scientific experts for creating risk awareness, understanding, and advice for action or preparedness for informed risk decisions. Scientific experts are expected to engage in risk communication with stakeholders at various levels, not least the general public. Scientific experts exist in organizations where forms and goals may vary, as well as in various industries. One such expert is the radiation protection expert, who exist in several organizational contexts. Responsibilities and requirements on communication are linked to the profession and a general supporting guideline on risk communication was in 2020 launched bythe International Radiation Protection Agency. However, less focus is on the organizational context such as how organizational conditions create opportunities and obstacles for the expert’s risk communication. The aim of this study was to analyze opportunities and limitations in organizational contexts and the significance they have on the experts’ communication on radiation risks. We study how the radiation protection expert understand their responsibility to communicate, how the expert is involved in communication, and how communication is shaped by the organizational context. The qualitative study focuses on radiation protection experts in three cases or contexts having different goals: an authority, a university hospital, and a European research infrastructure consortium. Communicative logics in the organizations was studied through text analyses of home pages and documents. In-depth interviews with radiation protection experts was conducted to learn about theircommunication strategies, practices, and experiences. The study show that high demands are put on the radiation protection expert to engage in communication with the public despite an often existing lack of training in communication. The experts have an implicit understanding of communication and their strategies are experience-based and context dependent. The study shows that communicative logics within the expert’s organization create some possibilities but also hindrances for the expert to communicate risk. Two such logics, the media and a promotional logic entails that certain stakeholders, channels and type of communication is prioritized. In both cases, experts are involved to a low extent and other aspects than risks are highlighted.

- The first genome-wide association study performed in a UK coeliac disease (CD) case-control cohort revealed association with a linkage disequilibrium block containing the KIAA1109/Tenr/IL2/IL21 genes. Also recently, an association with a non-synonymous polymorphism in Fcitalic gammaRIIa (CD32a) was reported in CD with an unusually strong P-value. We aimed to replicate the reported associations with the single nucleotide polymorphisms rs13119723 A>G and rs6822844 G>T in the KIAA1109/Tenr/IL2/IL21 region and rs1801274 G>A in the Fcitalic gammaRIIa gene in a family sample consisting of 325 Swedish/Norwegian families using the robust transmission disequilibrium test. The family sample used in this study included 100 families with two or more children affected by CD and 225 families with one affected child. We could confirm significant association between the polymorphisms rs13119723 A>G and rs6822844 G>T located in the KIAA1109/Tenr/IL2/IL21 region and CD (P-value 0.001 and 0.002, respectively). However, we found no association with the Fcitalic gammaRIIa rs1801274 G>A polymorphism (P-value=0.3). In conclusion, our results support the KIAA1109/Tenr/IL2/IL21 region as a true CD susceptibility region.

- Associations between epigenetic alterations and disease status have been identified for many diseases. However, there is no strong evidence that epigenetic alterations are directly causal for disease pathogenesis. In this study, we combined SNP and DNA methylation data with measurements of protein biomarkers for cancer, inflammation or cardiovascular disease, to investigate the relative contribution of genetic and epigenetic variation on biomarker levels. A total of 121 protein biomarkers were measured and analyzed in relation to DNA methylation at 470,000 genomic positions and to over 10 million SNPs. We performed epigenome-wide association study (EWAS) and genome-wide association study (GWAS) analyses, and integrated biomarker, DNA methylation and SNP data using between 698 and 1033 samples depending on data availability for the different analyses. We identified 124 and 45 loci (Bonferroni adjusted P < 0.05) with effect sizes up to 0.22 standard units' change per 1% change in DNA methylation levels and up to four standard units' change per copy of the effective allele in the EWAS and GWAS respectively. Most GWAS loci were cis-regulatory whereas most EWAS loci were located in trans. Eleven EWAS loci were associated with multiple biomarkers, including one in NLRC5 associated with CXCL11, CXCL9, IL-12, and IL-18 levels. All EWAS signals that overlapped with a GWAS locus were driven by underlying genetic variants and three EWAS signals were confounded by smoking. While some cis-regulatory SNPs for biomarkers appeared to have an effect also on DNA methylation levels, cis-regulatory SNPs for DNA methylation were not observed to affect biomarker levels. We present associations between protein biomarker and DNA methylation levels at numerous loci in the genome. The associations are likely to reflect the underlying pattern of genetic variants, specific environmental exposures, or represent secondary effects to the pathogenesis of disease.

- Learning from incidents is important for improving safety. Many companies spend a great deal of time and money on such learning procedures. The objectives of this paper are to present some early results from a project aimed at revealing weaknesses in the procedures for learning from incidents and to discuss improvements in these procedures, especially in chemical process industries. The empirical base comes from a project assessing organizational learning and the effectiveness of the different steps of the learning cycle for safety and studying relations between safety-specific transformational leadership, safety climate, trust, safety-related behavior and learning from incidents. The results point at common weaknesses in the organizational learning, both in the horizontal learning (geographical spread) and in vertical learning (double-loop learning). Furthermore, the effectiveness in the different steps of the learning cycle is low due to insufficient information in incident reports, very shallow analyses of reports, decisions that focus at solving the problem only at the place where the incident took place, late implementations and weak solutions. Strong correlations with learning from incidents were found for all safety climate variables as well as for safety-related behaviors and trust. The relationships were very strong for trust, safety knowledge, safety participation and safety compliance.

Konferensbidrag (refereegranskat)abstract
- Safety culture may be seen as the oil necessary for an efficient safety management system. During the work in HILAS SMS task force some weaknesses in the use of safety culture in practice were identified. A work stream was initiated to identify further weaknesses and suggest remedies for them. The objective of this paper is to discuss some of the weaknesses and propose mitigations. A major suggestion is to actively look for „holes‟ in the safety culture and mitigate them. The „holes‟ could be low-score groups, low-score aspects of safety culture, and critical time-windows. Also the efforts by top management may need to be improved. Also means for feed forward control should be used and further developed as proposed by the new school of resilience engineering. Also when problems with long questionnaires are too big shorter questionnaires could be used complemented by interviews and studies of behaviour and artefacts.

Tidskriftsartikel (refereegranskat)abstract
- Recent genome-wide association studies have identified 1q31 (RGS1), 2q11-12 (IL18RAP), 3p21 (CCR1/CCR3/CCR2), 3q25-26 (IL12A/SCHIP1), 3q28 (LPP), 4q27 (IL2/IL21), 6q25 (TAGAP) and 12q24 (SH2B3) as susceptibility regions for coeliac disease (CD). We have earlier replicated association with the IL2/IL21 region. This study aimed at replicating the remaining regions in a family cohort using the transmission disequilibrium test, which is not prone to population stratification as a source of false-positive results. Nine single nucleotide polymorphisms (SNPs) within these regions were genotyped in 325 Swedish-Norwegian CD families. We found significant associations with the same alleles in the regions 1q31 (rs2816316; P(nc)=0.0060), 3p21 (rs6441961; P(nc)=0.0006), 3q25-26 (rs17810564; P(nc)=0.0316 and rs9811792; P(nc)=0.0434) and 3q28 (rs1464510; P(nc)=0.0037). Borderline, but non-significant, associations were found for rs917997 (IL18RAP), whereas no evidence for association could be obtained for rs13015714 (IL18RAP) or rs1738074 (TAGAP). The lack of replication of the latter SNPs could be because of limited power. rs3184504 (SH2B3) was not analysed because of assay failure. The most significantly associated region, 3p21 (CCR1/CCR3/CCR2), was further analysed by typing of 30 SNPs, with the aim of identifying the causal variant responsible for the initial association. Several SNPs showed association with CD, but none displayed associations stronger than rs6441961, nor did any of them add to the effect initially marked by rs6441961 in a conditional analysis. However, differential effects of rs6441961(*)C carrying haplotypes were indicated, and we thus cannot exclude the possibility that our inability to obtain evidence for multiple independent effects in the CCR1/CCR3/CCR2 gene region was related to a power issue.

Tidskriftsartikel (refereegranskat)abstract
- In order to extend our previous findings of genetic linkage to the CD28/CTLA4/ICOS region on chromosome 2q33 (CELIAC3) in coeliac disease (CD), we have investigated 22 genetic markers in 325 Norwegian/Swedish multiplex and simplex CD families. We found both linkage and association with several markers, primarily in the multiplex material. We observed strong linkage disequilibrium (LD) between SNPs (Single Nucleotide Polymorphisms) within an LD block delimited by MH30 and D2S72. A haplotype of this region marked by the alleles -1147*T: + 49*A:CT60*G:CT61*A was significantly associated with CD, suggesting that one or more polymorphisms of this haplotype, possibly -1147*T, are involved in CD susceptibility. The CT60 SNP, a polymorphism found to be most strongly associated with some other immune-mediated diseases, was not associated with CD, as this SNP was part of both associated and non-associated haplotypes. Moreover, our results suggest that CELIAC3 harbours several independent loci contributing to CD susceptibility.

Tidskriftsartikel (refereegranskat)abstract
- For the transport sector to become more sustainable, substantial technological and behavioural changes are required. Increased understanding about household choices related to more green alternatives in transportation is needed in order for policy makers to make efficient policies in the future. The main purpose of this paper is to analyze which factors that determines the fuel choice between ethanol and gasoline for owners of flex-fuel vehicles (FFVs). We evaluate how the self-reported fuel choice is influenced by the relative price, as well as individual differences in norms and perceptions about environmental and quality attributes of ethanol. Data was collected through a survey sent to Swedish FFV owners and is analyzed in a binary choice and a LCM framework. Results show that price, perceptions about quality, age and environmental attitudes influence the self-reported willingness to choose ethanol. Furthermore, results show that preferences are not homogenous, three groups are identified; price conscious respondents, ethanol skeptical respondents and respondents with pronounced environmental concern. However, although the motive for introducing and subsidizing ethanol was to reduce climate and environmental impacts, the group that chooses ethanol based on climate and environmental motives is small. The results further reveal that the debate about motor damages from ethanol have had a long lasting effect on the willingness to choose ethanol. Thus, it is necessary to try to prevent or mitigate concerns regarding e.g. potential technical or ethical issues when promoting future technologies or fuels aimed at a sustainable transportation sector.

- In order to adapt to new conditions that increasing air traffic volumes bring forward, the Swedish Air Navigation Services (ANS) is going through a process of change. In order to meet the new conditions it will be necessary to be more efficient in the work of handling the air traffic. New conditions bring forward new demands, not only on technology and methods used, but also on organizational structures and individual employees. The challenge is to make the adaptation in ways that do not affect the safety standards. The Swedish air traffic control, ATC centers in Malmö and Stockholm are adjusting their activity to meet the new situations in mainly two ways: a new team-based organization has recently been introduced and a new ATC system will soon be installed.

- Air traffic control in Sweden is being studied in a joint long-term project between Lund University and the Swedish Air Navigation Services (ANS).The project aims to investigate how different organisational aspects such as organisational climate, team climate, leadership, psychosocial work environment and safety culture will be affected by ongoing organisational and technical changes. The basic research design comprises three studies, two prior to the introduction of a new air traffic control system and one after. This design has provided opportunities to compare the situation before and after the system introduction. The first and the second studies have been completed and the results concerning organisational climate and psychosocial work environment are the focus of this paper.

- A positive and innovative organizational climate is of great importance in order to manage and adapt to change. Such a climate seldom evolves in organizations closely governed by rules and regulations. Because of ongoing organizational and technical changes within the Swedish Air Navigation Services Provider, a study concerning the organizational climate for changes and innovations was conducted to investigate the organization’s capacity to cope with changes. Study locations were the two Swedish main air traffic control centers and parts of the civil aviation administration headquarters. 390 subjects took part in the study and the CCQ questionnaire was used to measure the organizational climate. The results show that the organizational climate is quite positive despite the rule governed work. The results also show that administrative personnel assess the organizational climate as more positive than operative personnel. Comparisons between management positions did not result in any differences.

Tidskriftsartikel (refereegranskat)abstract
- In high-risk environments such as air traffic control, leadership on different levels plays a certain role in establishing, promoting, and maintaining a good safety culture. The current study aimed to investigate how leadership styles, leadership style adaptability, and over and under task leadership behavior differed across situations, operative conditions, leadership structures, and working tasks in an air traffic control setting. Study locations were two air traffic control centers in Sweden with different operational conditions and leadership structures, and an administrative air traffic management unit. Leadership was measured with a questionnaire based on Leader Effectiveness and Adaptability Description (LEAD; Blanchard, Zigarmi & Zigarmi, 2003; Hersey & Blanchard, 1988). The results showed that the situation had strong impact on the leadership in which the leadership behavior was more relationship oriented in Success and Group situations than in Hardship and Individual situations. The leadership adaptability was further superior in Success and Individual situations compared with Hardship and Group situations. Operational conditions, leadership structures and working tasks were, on the other hand, not associated with leadership behavior.

Konferensbidrag (refereegranskat)abstract
- In a joint project – Human Factors in ANS, HUFA - between the Swedish Civil Aviation Administration and Lund University the aim is to find out how a new team-based organization and the introduction of a new air traffic control system will affect safety culture and psychosocial working environment by changes in organizational climate, team climate and leadership. All in all, four studies will be conducted, before and after the system introduction, involving the two air traffic control centers (ATCC) in Malmö and Stockholm as well as the air navigation services (ANS) division in Norrköping. This paper focus on findings from the first study concerning the team climate and the safety culture. The results show an overall positive picture concerning the safety culture at all three units. The team climate is assessed as average at the two ATCCs and just above at the ANS-division. No clear patterns could be found that can explain if and how the safety culture and the team climate are related.

Konferensbidrag (refereegranskat)abstract
- In a joint project between the Swedish Civil Aviation Administration (SCAA) and Lund University, questions concerning organizational aspects - such as organizational climate, team climate, situational leadership, psychosocial working environment - and safety culture are under study. A team-based organization has recently been introduced and a new air traffic control system will soon be installed at the two main air traffic control centers (ATCC) in Sweden. To find out how these changes will affect the organizational aspects and the safety culture, four studies will be conducted. These studies will involve the two air traffic control centers in Malmö and Stockholm as well as the Air Navigation Services Headquarters in Norrköping (ANS). The first study conducted about a year before the introduction of the new system, has been accomplished. The second study will be conducted just before the system introduction, the third directly after the introduction and the fourth approximately six months later. This design gives the opportunity to compare the situations before and after the system introduction.

Tidskriftsartikel (refereegranskat)abstract
- Twenty 10- to 18-year-old children and adolescents with varying degrees of hearing impairment (HI) and hearing aids (HA), ranging from mild-moderate to severe, produced picture-elicited narratives in a spoken and written version. Their performance was compared to that of 63 normally hearing (NH) peers within the same age span. The participants with HI and NH showed similar patterns regarding intragroup correlations between corresponding measures of spoken and written narratives. However, the participants with HI had significantly less diverse language than the NH group. The participants with poorer hearing (higher best ear hearing level [BEHL]) produced spoken and written narratives comprising more content words and they also produced written narratives that were less lexically diverse than the participants with better hearing (lower BEHL). The difference as to lexical skills emphasizes the importance of focusing on these skills in the group of children with HI. However, the results give support for a quite optimistic view on the development of narration in children with HI with HA, at least for picture-elicited narratives.
