Conference paper (peer-reviewed)abstract
- Förmågan att effektivt utnyttja och kritiskt förhålla sig till olika informationsresurser – ”information literacy” eller informationskompetens – är en central färdighet i det moderna samhället. Det utgör också en allt viktigare del av lärandet i högre utbildning. Syftet med detta paper är tvåfaldigt: 1) att problematisera relationen mellan informationskompetens som en generell färdighet och mer specifika ämnesorienterade kunskaper och färdigheter; 2) ge exempel på och utveckla redskap för lärare att på ett ämnesmässigt integrerat sätt arbeta med, utveckla och examinera studenternas informationskompetens. Ett huvudspår i framställningen är att synliggöra hur träningen i informationskompetens kan stimulera och hjälpa studenterna till fördjupade ämneskunskaper.

- OBJECTIVE: This study was performed to evaluate the use of high-risk HPV (hrHPV) viral load in screening tests for cervical cancer to predict persistent infection and presence of cervical intraepithelial neoplasia grade 2 or worse (CIN2+).METHODS: We followed women between 30 and 60 years of age who performed self-sampling of vaginal fluid and subsequently a hrHPV test. Women who were hrHPV positive in their screening test repeated the hrHPV test 3-6 months later and were included in the present study.RESULTS: Our results show that women with a persistent HPV16 infection had higher HPV viral load in their primary screening test than women with transient infections (p = 5.33e-03). This was also true for sum of viral load for all hrHPV types in the primary screening test (p = 3.88e-07). 48% of women with persistent HPV16 infection and CIN2+ had an increase in HPV16 titer in the follow-up test, as compared to only 20% of women with persistent infection but without CIN2+ lesions. For the sum of all hrHPV types, 41% of women with persistent infection and CIN2+ had an increase in titer as compared to 26% of women without CIN2 + .CONCLUSIONS: The results show that hrHPV viral load in the primary screening HPV test is associated with the presence of CIN2+ and could be used in triaging hrHPV positive women for different follow-up strategies or recall times. Serial testing of hrHPV viral load has the potential to distinguish women with CIN2+ lesions from women with persistent infection but without CIN2+ lesions.

Journal article (peer-reviewed)abstract
- BackgroundThe vaginal microbiota has been reported to be associated with HPV infection and cervical cancer. This study was performed to compare the vaginal microbiota at two timepoints in women performing self-sampling and had a persistent or transient HPV16 infection. The women were tested for 12 high-risk HPV (hrHPV) types but only women with single type (HPV16) were included to reduce confounding variables.MethodsIn total 96 women were included in this study. Of these, 26 were single positive for HPV16 in the baseline test and HPV negative in the follow-up test and 38 were single positive for HPV16 in both tests and diagnosed with CIN2+ in histology. In addition, 32 women that were negative for all 12 HPV tested were included. The samples of vaginal fluid were analyzed with the Ion 16S™ Metagenomics Kit and Ion 16S™ metagenomics module within the Ion Reporter™ software.ResultsK-means clustering resulted in two Lactobacillus-dominated groups, one with Lactobacillus sp. and the other specifically with Lactobacillus iners. The two remaining clusters were dominated by a mixed non-Lactobacillus microbiota. HPV negative women had lower prevalence (28%) of the non-Lactobacill dominant cluster in the baseline test, as compared to women with HPV16 infection (42%) (p value = 0.0173). Transition between clusters were more frequent in women with persistent HPV16 infection (34%) as compared in women who cleared the HPV16 infection (19%) (p value = 0.036).ConclusionsThe vaginal microbiota showed a higher rate of transitioning between bacterial profiles in women with persistent HPV16 infection as compared to women with transient infection. This indicate an instability in the microenvironment in women with persistent HPV infection and development of CIN2+.

- PROBLEM: Regulatory T cells (Treg cells), a small subset of CD4(+) T cells maintaining tolerance by immunosuppression, are proposed contributors to the survival of the fetal semiallograft. We investigated Treg cells in paired decidual and peripheral blood (PB) samples from healthy women in early pregnancy and PB samples from non-pregnant women.METHOD OF STUDY: Distribution, location, cytokine mRNA, and phenotype were assessed in CD4(+) CD25(+) Treg cells from paired samples using immunohistochemistry, immunofluorescence, flow cytometry, and real-time quantitative RT-PCR.RESULTS: The presence and in situ distribution of CD4(+) Foxp3(+) Treg cells in decidua are hereby demonstrated for the first time. Three Foxp3(+) cell populations, CD4(+) CD25(++) Foxp3(+), CD4(+) CD25(+) Foxp3(+), and CD4(+) CD25(-) Foxp3(+), were enriched locally in decidua. In contrast, no statistically significant difference in numbers of circulating Treg cells between pregnant and non-pregnant women was found. The Foxp3(+) cells expressed the surface molecules CD45RO, CTLA-4, CD103, Neuropilin-1, LAG-3, CD62L, and TGFβ1 mRNA consistent with Treg phenotype. The population of CD4(+) CD25(-) Foxp3(+) cells, not described in human decidua before, was enriched 10-fold compared with PB in paired samples. Their cytokine expression was often similar to Th3 profile, and the Foxp3 mRNA expression level in CD4(+) CD25(-) cells was stable and comparable to that of CD4(+) CD25(+) Treg cells implying that the majority of CD4(+) CD25(-) Foxp3(+) cells might be naïve Treg cells.CONCLUSION: (i) There is a local enrichment of Treg cells in decidua (ii) The exclusive accumulation of decidual CD4(+) CD25(-) Foxp3(+) cells suggests an additional reservoir of Foxp3(+) naïve Treg cells that can be converted to 'classical' Treg cells in uterus.

Journal article (peer-reviewed)abstract
- Background/aim: The lowering of natively analyzed Aβ42 in cerebrospinal fluid (CSF) is used as a diagnostic tool in Alzheimer’s disease (AD). Presence of Aβ oligomers can interfere with such analyses causing underestimation of Aβ levels due to epitope masking. The aim was to investigate if the lowering of CSF Aβ42 seen is caused by oligomerization. Methods: Aβ42 was analyzed under both denaturing and non-denaturing conditions. An Aβ42 oligomer ratio was calculated from these quantifications. Presence of oligomers leads to Aβ42 epitope masking during non-denaturing assays, resulting in a higher ratio. Results: The Aβ42 oligomer ratio was used for assessment of oligomerized Aβ in human CSF, after being evaluated in transgenic mouse brain homogenates. AD and mild cognitive impairment (MCI) samples displayed the expected decrease in natively measured Aβ42 compared to healthy controls and frontotemporal dementia, but not when analyzing under denaturing conditions. Accordingly, AD and MCI CSF had a higher Aβ42 oligomer ratio in CSF. Conclusion: Combining denaturing and non-denaturing quantifications of Aβ42 into an oligomer ratio enables assessment of Aβ oligomers in biological samples. The increased Aβ42 oligomer ratio for AD and MCI indicates presence of oligomers in CSF and that the lowering of natively measured Aβ42 is caused by oligomerization.

Journal article (peer-reviewed)abstract
- We conducted a randomised study to compare vaginal self-sampling with assisted sampling by medical personnel on the cervix for HPV testing in primary screening. The first aim was to determine if the HPV prevalence is independent of sampling location (vagina versus cervix) and the person performing the sampling. The second aim was to evaluate if the two sampling strategies differed in the detection rate of CIN2+. In total, 19,523 women were randomised into two groups, with 9926 invited to perform self-sampling (SS arm) using the Rover VIBA-brush and 9597 offered assisted sampling using the cytobrush (AS arm). All samples were applied to the indicating FTA elute card and analysed for high-risk HPV using the hpVIR real-time PCR assay. The outcome for the first aim was HPV prevalence and for the second aim the number of CIN2+ based on histology. In the SS arm, 52.7% of invited women participated in the study, as compared to 34.2% in the AS arm. All samples contained sufficient amount of nuclear DNA for a valid HPV result, with vaginal samples having a higher DNA amount than cervical samples (p < 4.62 × 10-11 ). HPV prevalence was 4.6% in the SS arm and 4.1% in the AS arm (p = 5.5 × 10-2 ), and the distribution of HPV types similar between arms. There was no difference in the prevalence of CIN2+ per 1000 women screened between arms (p = 0.86). The results show that vaginal self-sampling is an equivalent alternative to sampling by medical personnel for HPV typing and identification of CIN2+.

Journal article (peer-reviewed)abstract
- Background:This randomised study compared the detection rate of cervical intraepithelial neoplasia-positive (CIN2+) based on histology in women performing repeated self-sampling of vaginal fluid (VF) for human papillomavirus (HPV) test with a control group following the ordinary screening by Pap smear cytology.Methods:36390 women aged 30–49 years scheduled for invitation to organised screening were randomised in two groups, one to perform self-sampling of VF for HPV test (n=17 997, HPV arm) and the other group to perform screening by PAP smear cytology (n=18 393, control arm). HPV positive women in the HPV arm repeated the self-sampling and the HPV test on average 4.4 months later and those with two consecutive positive HPV tests were referred to colposcopy. Outcome was CIN2+ based on histology during 18-month follow-up.Results:Participation rate was 47% in the HPV arm and 39% in the control arm. The HPV prevalence in the first self-sampling was 6.9%, and 71% of these women were HPV positive in their second test. For the per-protocol approach, cumulative prevalence of histological CIN2+ in the HPV arm was 20.2 per 1000 women screened as compared to 10.8 in the control arm. The cumulative prevalence of CIN2+ diagnosed per 1000 years screened was 160.8 in the HPV arm as compared with 25.4 in the control arm.Conclusions:Repeated self-sampling of VF and HPV test had more than a two-fold higher discovery rate of CIN2+ per 1000 women screened as compared with PAP smear cytology.

New steering methods in regional policy : transforming the alliance of ‘state feminism’
- 2012

In: Women's Studies. - : Elsevier BV. - 0277-5395 .- 1879-243X. ; 35:3, s. 166-172

Journal article (peer-reviewed)abstract
- In this article, the theory of ‘state feminism’ is applied on the area of regional development policy, supplementing existing research about state–citizen relationships in northern and southern Europe. Based on Swedish data, it is argued that the former alliance between the women's movement and the welfare state has been transformed as a result of new steering methods in regional development policy in a way that is best understood as a paradox. This paradox includes both stronger and weaker relations. The public support to Women Resource Centres (WRCs) in Sweden is used as an example of ‘state feminism’. The ability of the WRCs to affect policy has changed over time, however, due to the adoption of new steering methods based on networks and market-orientation in Swedish regional development policy. The conclusions induce further development of ‘state feminism’ theory, making it more up-to-date with the prevalent interaction between women's movements and European welfare states.
