- Aim: It is unknown whether food allergies have greater impact on quality of life than respiratory allergies. This study compared health-related quality of life (HRQoL) in children allergic to wheat or grass. Methods: We surveyed 63 children with wheat allergies (median age of five) and 72 with grass allergies (median age 12), with their parents. The Child Health Questionnaires for parents (CHQ-PF28) and children (CHQ-CF87) were applied. Results: The parents of children in the wheat group recorded significantly lower CHQ-PF28 scores for the impact of their child's allergy on general behaviour, general health perceptions, parental impact of emotions and time and family activities, than the parents of children with grass allergies (p values ≤0.001). However, parents in the grass group recorded lower scores for the change in health item than the parents of children with wheat allergies (p = 0.020). In the grass group, children and parents reported similar scores for the different questions, but there was poorer correlation between parents and children in the wheat allergy group. Conclusion: HRQoL was lower in children with wheat than grass allergies according to parental reports, with more consistent perceptions of HRQoL among parents and children in the grass allergy than wheat allergy group.

- Angular correlations between charged trigger and associated particles are measured by the ALICE detector in p-Pb collisions at a nucleon-nucleon centre-of-mass energy of 5.02 TeV for transverse momentum ranges within 0.5 < P-T,P-assoc < P-T,P-trig < 4 GeV/c. The correlations are measured over two units of pseudorapidity and full azimuthal angle in different intervals of event multiplicity, and expressed as associated yield per trigger particle. Two long-range ridge-like structures, one on the near side and one on the away side, are observed when the per-trigger yield obtained in low-multiplicity events is subtracted from the one in high-multiplicity events. The excess on the near-side is qualitatively similar to that recently reported by the CMS Collaboration, while the excess on the away-side is reported for the first time. The two-ridge structure projected onto azimuthal angle is quantified with the second and third Fourier coefficients as well as by near-side and away-side yields and widths. The yields on the near side and on the away side are equal within the uncertainties for all studied event multiplicity and p(T) bins, and the widths show no significant evolution with event multiplicity or p(T). These findings suggest that the near-side ridge is accompanied by an essentially identical away-side ridge. (c) 2013 CERN. Published by Elsevier B.V. All rights reserved.

Tidskriftsartikel (refereegranskat)abstract
- The ALICE experiment at the LHC has studied J/psi production at mid-rapidity in pp collisions at root s = 7 TeV through its electron pair decay on a data sample corresponding to an integrated luminosity L-int = 5.6 nb(-1). The fraction of J/psi from the decay of long-lived beauty hadrons was determined for J/psi candidates with transverse momentum p(t) > 1,3 GeV/c and rapidity vertical bar y vertical bar < 0.9. The cross section for prompt J/psi mesons, i.e. directly produced J/psi and prompt decays of heavier charmonium states such as the psi(2S) and chi(c) resonances, is sigma(prompt J/psi) (p(t) > 1.3 GeV/c, vertical bar y vertical bar < 0.9) = 8.3 +/- 0.8(stat.) +/- 1.1 (syst.)(-1.4)(+1.5) (syst. pol.) mu b. The cross section for the production of b-hadrons decaying to J/psi with p(t) > 1.3 GeV/c and vertical bar y vertical bar < 0.9 is a sigma(J/psi <- hB) (p(t) > 1.3 GeV/c, vertical bar y vertical bar < 0.9) = 1.46 +/- 0.38 (stat.)(-0.32)(+0.26) (syst.) mu b. The results are compared to QCD model predictions. The shape of the p(t) and y distributions of b-quarks predicted by perturbative QCD model calculations are used to extrapolate the measured cross section to derive the b (b) over bar pair total cross section and d sigma/dy at mid-rapidity.

Tidskriftsartikel (refereegranskat)abstract
- We present measurements of Underlying Event observables in pp collisions at root s = 0 : 9 and 7 TeV. The analysis is performed as a function of the highest charged-particle transverse momentum p(T),L-T in the event. Different regions are defined with respect to the azimuthal direction of the leading (highest transverse momentum) track: Toward, Transverse and Away. The Toward and Away regions collect the fragmentation products of the hardest partonic interaction. The Transverse region is expected to be most sensitive to the Underlying Event activity. The study is performed with charged particles above three different p(T) thresholds: 0.15, 0.5 and 1.0 GeV/c. In the Transverse region we observe an increase in the multiplicity of a factor 2-3 between the lower and higher collision energies, depending on the track p(T) threshold considered. Data are compared to PYTHIA 6.4, PYTHIA 8.1 and PHOJET. On average, all models considered underestimate the multiplicity and summed p(T) in the Transverse region by about 10-30%.

Tidskriftsartikel (refereegranskat)abstract
- Background: Specific immunoglobulin E (IgE) sensitization to wheat is more common than a doctor's confirmed wheat allergy and is also frequently observed in grass pollen-allergic patients (pollinosis patients). Thus, the objective of this study was to investigate the level and feature of serological IgE cross-reactivity between grass pollen and wheat in a cohort of pollinosis subjects with no diagnosis of wheat allergy. Methods: Seventy-two children, aged 5-17 years, with a doctor's diagnosis of pollinosis, IgE towards grass pollen, and currently eating wheat were recruited. Serum samples were analyzed for IgE against wheat, timothy grass/wheatspecific allergen components, Pru p 3, and cross-reactive carbohydrate determinants (CCD) and specific IgE-binding inhibition experiments were performed. Results: Sixty per- cent of the grass pollen subjects were sensitized to wheat with a median of 0.5 kU(A)/L. Wheat-sensitized subjects were more often sensitized to the two allergens, Phl p 12 and CCD, known to be cross-reactive between grass and wheat. Sensitizations to seven wheat-specific allergens derived from the gluten fraction were, with the exception of one individual, only found in wheat-sensitized subjects. These subjects also more often reported current and past history of allergy to staple foods (milk, egg, wheat, soy, and fish). Conclusion: Wheat sensitization caused by cross-reactivity but also by sensitization to wheat-specific allergens was common in the grass-allergic children and also associated with allergy to staple foods other than wheat. The results indicate the presence of a subgroup of pollinosis patients with simultaneous sensitization to wheat and food allergy not only caused by cross-reactions.

Tidskriftsartikel (refereegranskat)abstract
- IntroductionWheat sensitization is common but IgE antibodies (IgE-abs) to wheat are not predictive of clinical symptoms in children with suspected wheat allergy. Wheat allergen components other than -5gliadin have not been well studied. Our aim was to characterize the clinical profile and investigate the value of adding measurements of IgE-abs to wheat components in a group of children with a doctor's diagnosed wheat allergy. MethodSixty-three children with a doctor's diagnosis of wheat allergy confirmed sensitization to wheat and, on a wheat elimination diet, went through oral wheat challenges or had a convincing recent history of wheat allergy. IgE-ab to -5 gliadin, low molecular weight glutenin (LMW-glutenin), high molecular weight glutenin (HMW-glutenin) and a native gliadin preparation containing -, -, -, and -gliadin (gliadin) were analyzed. ResultsTwenty-six children were positive in challenge, while six children were regarded as wheat allergic due to recent anaphylactic reactions. The IgE-ab levels to all four wheat components were significantly higher in the group with wheat allergy compared to the group with no wheat allergy (p<0.0001). Also, the severity of symptoms at challenge correlated with the IgE-ab levels to all four components (p<0.05). IgE-ab levels to -5 gliadin correlated best with challenge outcome, and by additional analysis of gliadin, HMW- and LMW-glutenin IgE-abs all challenge positive children could be identified. ConclusionMany children diagnosed as wheat allergic have outgrown their allergy and are unnecessarily on a wheat-free diet. The levels of IgE-ab to wheat gluten-derived components correlated well with wheat challenge outcome and severity.

Spelets regler : raggning och flirt på krogen

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- This thesis focuses on sexualized behaviour in nightclubs and pubs. It describes the patterns of interaction and the rituals characterizing nightlife “clubbing” and “pubbing” environments, and relates these to gender specific norms and ideals. Special focus is on men’s and women’s experiences of, and strategies in, nightlife clubbing environments, as well as on how they regard such behaviours as picking up potential sexual partners (“going on the pull”) and flirting.The study is based on fieldwork conducted in the nightclubs and pubs of Umeå. The fieldwork consisted of fifty nights out, during which data was collected through observations and participant observation. Ten women and nine men between the ages of twenty-one and thirty-two were interviewed individually or in groups.The analysis starts with a description of those behaviours that distinguish the club and pub environment as compared with everyday life. The suspension of everyday norms, allows for the relaxed behaviour associated with “partying”, and not least allowing for strangers to have sexualized encounters.Picking up sexual partners and flirting is analysed at different levels and from different perspectives. The meaning of flirting behaviour is related to discussions of sexual morals. Flirting is seen as a harmless and playful form of behaviour seeped through with notions of love, romance and coupledom. Picking up sexual partners is, on the other hand, behaviour associated with sexual urges, and is thus talked of as a sordid, low-life form of action.The study includes descriptions of mutually appreciated situations of picking-up and flirting behaviour and also its opposite - rejection behaviours, that seek to deflect and break off attempts at sexualized contact. The observations indicate that men and women use different strategies when participating in such events. Women’s behavioural strategies are premised on a rejecting attitude vis-à-vis men, which reflect ideals of respectability and a more restrictive sexual morale for women. Women’s ability to exert discretion and care in her choice of a man, and to reject unsuitable men, is interpreted as an indication of self-control and self-respect.Amongst men, “going on the pull” appears to be associated with notions of “conquering”, which in turn is seen as a form of manly performance. “Going on the pull” gives men an opportunity to prove themselves, but is also a source of a feeling of powerlessness and lack of control – as “pulling” needs to be conducted on women’s terms and conditions.Observations from pubs and clubs in the field, suggest that pretending to reject (token resistance) is a normalized part of women’s strategies. The existence of token resistance reinforces the notion of “a woman’s no means yes” and contributes to the unclear boundaries between rejection and consent. This is evident in situations where women experience unwished-for attentions from men and have difficulty rejecting them.

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- The program in Social Psychiatric Care is a three-year program at the university level leading to a vocational qualification in social psychiatric care and a bachelor's degree in the field of Health Sciences. Until the spring of 2018, six litters have graduated. Students in the social psychiatric care program often have personal interest, previous professional experience from the business areas or inspiration from related friends working in the field of activity. Personal experiences of problems in the fields of activity are also prominent among the students. Students believe that personal experience, willingness and ability is important in order to work within the profession. Characteristics of the students are also an interest and a clear empathetic willingness to work with people and they consider that the profession primarily requires characteristics such as altruism, empathy, social skills and deeper knowledge and understanding in the field. Upon completion of education, students want a career role where they can help other people, feel motivated, or they aim for specific positions or areas of activity. Both managers and alumni from the Social Psychiatric Care program value the broad professional competence that the program leads to. Psychiatric competence is emphasized as particularly valuable by both alumni and managers. This competence means that they also complement the other professions in the activities. Students consider themselves possessed a professional identity that involves introducing psychiatric and custody skills to organizations that previously lacked these perspectives. Something that also brings new approaches to patients, users and clients. Being able to use knowledge from several disciplines are considered to be a strength and competence that are well-needed in environments where people with mental ill health are cared for. The alumni perceive their knowledge as both interdisciplinary and interprofessional.

The role of natural killer cells and inflammatory mediators in preeclamptic pregnancies
- 2008
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The maternal immune system must be able to adjust during pregnancy and accept the foetus that expresses paternal antigens. These changes are found both in placenta and circulation, including a mild inflammatory response. NK cells are abundant during the early part of pregnancy in placenta and are thought to be important for placental development. During preeclampsia the placenta is poorly developed, together with an escalated pro-inflammatory profile noticed in both placenta and circulation. We wanted to study NK cells in placenta and circulation from preeclamptic cases as well as levels of cytokines. HMGB1, an alarmin involved in inflammation, was also measured in preeclamptic placentae.When studying preeclamptic placentae in third trimester we found higher numbers of NK cells as well as a higher expression of CD94+ NK cells. We also found slightly elevated levels of HMGB1 together with significantly lower expression of IL-12 in preeclamptic placentae. Further, the NK cell activating cytokines IL-12/IL-23p40 and IL-15 in sera from preeclamptic women were increased compared to healthy pregnancies. The elevated levels of NK cell activating IL-12/IL-23p40 and IL-15 found in preeclamptic sera, made us investigate the circulating NK cells in preeclampsia. However, no differences were seen between healthy and preeclamptic pregnancies.The main immunological alterations in third trimester preeclamptic pregnancies with regard to NK cells were found in placenta. Altered maternal cytokine levels in placenta could influence decidual NK cells in preeclampsia, noticed by their higher numbers and altered receptor expression. If these alterations also exist during early pregnancy it could result in a poorly developed and dysfunctional placenta.
