    Antenatal Corticosteroids and Postnatal Fluid Restriction Produce Differential Effects on AQP3 Expression, Water Handling, and Barrier Function in Perinatal Rat Epidermis2010Ingår i: Dermatology research and practice, ISSN 1687-6113Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Loss of water through the immature skin can lead to hypothermia and dehydration in preterm infants. The water and glycerol channel aquaglyceroporin-3 (AQP3) is abundant in fetal epidermis and might influence epidermal water handling and transepidermal water flux around birth. To investigate the role of AQP3 in immature skin, we measured in vivo transepidermal water transport and AQP3 expression in rat pups exposed to clinically relevant fluid homeostasis perturbations. Preterm (E18) rat pups were studied after antenatal corticosteroid exposure (ANS), and neonatal (P1) rat pups after an 18 h fast. Transepidermal water loss (TEWL) and skin hydration were determined, AQP3 mRNA was quantified by RT-PCR, and in-situ hybridization and immunocytochemistry were applied to map AQP3 expression. ANS resulted in an improved skin barrier (lower TEWL and skin hydration), while AQP3 mRNA and protein increased. Fasting led to loss of barrier integrity along with an increase in skin hydration. These alterations were not paralleled by any changes in AQP3. To conclude, antenatal corticosteroids and early postnatal fluid restriction produce differential effects on skin barrier function and epidermal AQP3 expression in the rat. In perinatal rats, AQP3 does not directly determine net water transport through the skin.

    Invisibility of Racism in the Global Neoliberal Era: Implications for Researching Racism in Healthcare2019Ingår i: Frontiers in Sociology, ISSN 2297-7775Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This paper describes the difficulties of researching racism in healthcare contexts as part of the wider issue of neoliberal reforms in welfare states in the age of global migration. In trying to understand the contradiction of a phenomenon that is historical and strongly felt by individuals and yet widely denied by both institutions and individuals, we consider the current political and socioeconomic context of healthcare provision. Despite decades of legislation against racism, its presence persists in healthcare settings, but data on these experiences is rarely gathered in Europe. National systems of healthcare provision have been subject to neoliberal reforms, where among others, cheaper forms of labor are sought to reduce the cost of producing healthcare, while the availability of services is rationed to contain demand. The restriction both on provision of and access to welfare, including healthcare, is unpopular among national populations. However, the explanations for restricted access to healthcare are assumed to be located outside the national context with immigrants being blamed. Even as migrants are used as a source of cheap labor in healthcare and other welfare sectors, the arrival of immigrants has been held responsible for restricted access to healthcare and welfare in general. One implication of (im)migration being blamed for healthcare restrictions, while racism is held to be a problem of the past, is the silencing of experiences of racism, which has dire consequences for ethnic minority populations. The implications of racism as a form of inequality within healthcare and the circumstances of researching racism in healthcare and its implication for the sociology of health in Sweden are described.

    ‘"A child, a tree": Challenges in building collaborative relations in a community research project in a Kenyan context2016Ingår i: Action Research, ISSN 1476-7503, E-ISSN 1741-2617, Vol. 14, nr 3, s. 257-275Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This paper highlights the potential for basing participatory action research on priorities identified by communities. The case builds on a research project by the Social Science Medicine Africa Network (Soma-net) focusing on AIDS prevention among school youth in Kajiado in Kenya during 2003-2006. It became clear from that study just how complex it is to promote open communication on issues of sexuality considered critical for sexual health promotion. Towards the end of that study a spin-off in the form of a concept a child, a tree or tree planting evolved and the research thereafter continued as a partnership between the school community and the researchers. The focus then was on understanding how health promotion could be integrated into other aspects of community life. The concept and tree planting when implemented created a sense of ownership among the pupils largely because they were placed at the centre of the development activities. The story illuminates the nature of change developing in the course of the project, but also the challenges and complexity of creating and maintaining collaborative relations in the face of cultural and gender power dynamics and interventions imposed from outside the community.

    'Not men enough to rule!': politicization of ethnicities and forcible circumcision of Luo men during the postelection violence in Kenya2013Ingår i: Ethnicity and Health, ISSN 1355-7858, E-ISSN 1465-3419, Vol. 18, nr 5, s. 454-468Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background

    As a contribution to ongoing research addressing sexual violence in war and conflict situations in the Democratic Republic of Congo, Kenya and Rwanda, this paper argues that the way sexual violence intersects with other markers of identity, including ethnicity and class, is not clearly articulated. Male circumcision has been popularized, as a public health strategy for prevention of HIV transmission, although evidence of its efficacy is disputable and insufficient attention has been given to the social and cultural implications of male circumcision.

    Methods

    This paper draws from media reporting and the material supporting the prosecutor at the International Criminal Court case against four Kenyans accused of crimes against humanity, to explore the postelection violence, especially forcible male circumcision.

    Results

    During the postelection violence in Kenya, women were, as in other conflict situations, raped. In addition, men largely from the Luo ethnic group were forcibly circumcised. Male circumcision among the Gikuyu people is a rite of passage, but when forced upon the Luo men, it was also associated with cases of castration and other forms of genital mutilation. The aim appears to have been to humiliate and terrorize not just the individual men, but their entire communities. The paper examines male circumcision and questions why a ritual that has marked a life-course transition for inculcating ethical analysis of the self and others, became a tool of violence against men from an ethnic group where male circumcision is not a cultural practice.

    Conclusion

    The paper then reviews the persistence and change in the ritual and more specifically, how male circumcision has become, not just a sexual health risk, but, contrary to the emerging health discourse and more significantly, a politicized ethnic tool and a status symbol among the Gikuyu elite. In the view of the way male circumcision was perpetrated in Kenya, we argue it should be considered as sexual violence, with far-reaching consequences for men's physical and mental health.

    Retrospective serological and virological survey of influenza D virus among cattle in Sweden2019Självständigt arbete på grundnivå (yrkesexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    Respiratory diseases in cattle can cause economic losses due to the decreased dairy and meat production. Virus is the main reason for these diseases. Symptoms can be fever, cough and nasal discharge.

        Influenza are a group of viruses belonged in the Ortomyxoviridae family. The big influenza groups are influenza A, B and C. The viruses can cause respiratory signs, and mammals can be affected. Recently a new influenza virus was found in the United States. The influenza virus was found in swine, but the natural host was later considered to be cattle. The virus was named influenza D. Different studies worldwide have confirmed the virus in a variety of regions. Antibodies have also been reported.

        In this study, virologic and serologic methods were used to detect if influenza D circulates among cattle in Sweden. The serologic method performed was indirect ELISA. Serum and milk samples were investigated in the ELISA method. For the virologic detection a real-time RT-PCR was made, with a variety of study material.

        Antibodies against influenza D were found in both serum and milk samples. No virus was found in the real-time RT-PCR. In Sweden the animal keeping is different compared to several other nations. For instance, the conditions of health and hygiene are better in Sweden, this may be an important cause of a system more resistant against spreading of infections. Influenza D could be more common in Sweden, but in that case further researches are needed to determine the prevalence.

    Increased IL-17A secretion in response to Candida albicans in autoimmune polyendocrine syndrome type 1 and its animal model2011Ingår i: European Journal of Immunology, ISSN 0014-2980, E-ISSN 1521-4141, Vol. 41, nr 1, s. 235-245Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Autoimmune polyendocrine syndrome type 1 (APS-1) is a multiorgan autoimmune disease caused by mutations in the autoimmune regulator (AIRE) gene. Chronic mucocutaneous candidiasis, hypoparathyroidism and adrenal failure are hallmarks of the disease. The critical mechanisms causing chronic mucocutaneous candidiasis in APS-1 patients have not been identified although autoantibodies to cytokines are implicated in the pathogenesis. To investigate whether the Th reactivity to Candida albicans (C. albicans) and other stimuli was altered, we isolated PBMC from APS-1 patients and matched healthy controls. The Th17 pathway was upregulated in response to C. albicans in APS-1 patients, whereas the IL-22 secretion was reduced. Autoantibodies against IL-22, IL-17A and IL-17F were detected in sera from APS-1 patients by immunoprecipitation. In addition, Aire-deficient (Aire(0/0) ) mice were much more susceptible than Aire(+/+) mice to mucosal candidiasis and C. albicans-induced Th17- and Th1-cell responses were increased in Aire(0/0) mice. Thus an excessive IL-17A reactivity towards C. albicans was observed in APS-1 patients and Aire(0/0) mice.

    Comparison of Molecular Multiplex and Singleplex Analysis of IgE to Grass Pollen Allergens in Untreated German Grass Pollen-Allergic Patients2015Ingår i: Journal of investigational allergology & clinical immunology, ISSN 1018-9068, E-ISSN 1698-0808, Vol. 25, nr 3, s. 190-195Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: The ImmunoCAP ISAC 112 platform is the only commercially available molecular allergy IgE multiplex test. Data on the comparison of this rather novel test with the molecular singleplex ImmunoCAP IgE platform are lacking. Objective:To compare the multiplex ISAC 112 platform and the singleplex ImmunoCAP platform in regard to IgE to grass pollen allergens in untreated grass pollen allergic patients in Germany. Methods: Serum samples from 101 adults with grass pollen allergy were analyzed for specific IgE (sIgE) to 8 allergenic molecules from timothy grass pollen and to the 112 allergenic molecules included in the ISAC panel. The results for the multiplex and singleplex tests were subsequently analyzed statistically. Results: Comparison of sIgE to grass pollen allergens detected by ISAC 112 and the singleplex ImmunoCAP assay revealed the following correlation coefficients: 0.88 (rPhl p1), 0.96 (rPhl p2), 0.70 (nPhl p4), 0.94 (rPhl p5b), 0.92 (rPhl p6), 0.85 (rPhl p11), and 0.78 (rPhl p12). Conclusion: Molecular testing with ISAC 112 correlates well with the ImmunoCAP platform for respective molecular timothy grass pollen allergens.

    Being Born Large for Gestational Age: Metabolic and Epidemiological Studies2008Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    Obesity is a major health problem in the Western world. Mean birth weight has increased during the last 25 years. One explanation is that the proportion of large for gestational age (LGA) infants has increased. Such infants risk developing obesity, cardiovascular disease and diabetes later in life. Despite the risk of neonatal hypoglycemia, their postnatal metabolic adaptation has not been investigated. Our data, obtained with stable isotope labeled compounds, demonstrate that newborn LGA infants have increased lipolysis and decreased insulin sensitivity. After administration of glucagon, the plasma levels of glucose and the rate of glucose production increased. The simultaneous increase in insulin correlated with the decrease in lipolysis, indicating an antilipolytic effect of insulin in these infants.

    We also demonstrated an intergenerational effect of being born LGA, since women born LGA, were at higher risk of giving birth to LGA infants than women not born LGA. Further, the LGA infants formed three subgroups: born long only, born heavy only, and born both long and heavy. Infants born LGA of women with high birth weight or adult obesity were at higher risk of being LGA concerning weight alone, predisposing to overweight and obesity at childbearing age. In addition we found that pregnant women with gestational diabetes were at increased risk of giving birth to infants that were heavy alone. This could explain the risk of both perinatal complications and later metabolic disease in infants of this group of women.

    To identify determinants of fetal growth, 20 pregnant women with a wide range of fetal weights were investigated at 36 weeks of gestation. Maternal fat mass was strongly associated with insulin resistance. Insulin resistance was related to glucose production, which correlated positively with fetal size. The variation in resting energy expenditure, which was closely related to fetal weight, was largely explained by BMI, insulin resistance, and glucose production. Lipolysis was not rate limiting for fetal growth in this group of women. Consequently, high maternal glucose production due to a high fat mass may result in excessive fetal growth.

    Gene Expression in Placentas From Nondiabetic Women Giving Birth to Large for Gestational Age Infants2015Ingår i: Reproductive Sciences, ISSN 1933-7191, E-ISSN 1933-7205, Vol. 22, nr 10, s. 1281-1288Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Gestational diabetes, obesity, and excessive weight gain are known independent risk factors for the birth of a large for gestational age (LGA) infant. However, only 1 of the 10 infants born LGA is born by mothers with diabetes or obesity. Thus, the aim of the present study was to compare placental gene expression between healthy, nondiabetic mothers (n = 22) giving birth to LGA infants and body mass index-matched mothers (n = 24) giving birth to appropriate for gestational age infants. In the whole gene expression analysis, only 29 genes were found to be differently expressed in LGA placentas. Top upregulated genes included insulin-like growth factor binding protein 1, aminolevulinate synthase 2, and prolactin, whereas top downregulated genes comprised leptin, gametocyte-specific factor 1, and collagen type XVII 1. Two enriched gene networks were identified, namely, (1) lipid metabolism, small molecule biochemistry, and organismal development and (2) cellular development, cellular growth, proliferation, and tumor morphology.

    Abstract [en]

    OBJECTIVE. In addition to neonatal hypoglycemia, infants who are born large for gestational age are at risk for developing obesity, cardiovascular disease, and diabetes later in life. The aim of this study was to investigate glucose production, lipolysis, and insulin sensitivity in infants who were born large for gestational age to mothers without diabetes. The effect of glucagon administration on production of energy substrates was also investigated.

    METHODS. Ten healthy term infants who were born large for gestational age to mothers without diabetes were studied 16 ± 8 hours postnatally after a 3-hour fast. Rates of glucose production and lipolysis were analyzed by gas chromatography–mass spectrometry following constant rate infusion of [6,6-2H2]glucose and [2-13C]glycerol. Insulin sensitivity was assessed by the Homeostasis Assessment Model. In 8 of the infants, the effect of an intravenous injection of 0.2 mg/kg glucagon was also analyzed.

    RESULTS. Plasma glucose and glycerol averaged 3.8 ± 0.5 mmol/L and 384 ± 183 µmol/L, respectively. The glycerol production rate, reflecting lipolysis, was 12.7 ± 2.9 µmol/kg per min. Mean rate of glucose production was 30.2 ± 4.6 µmol/kg per min. Homeostasis Assessment Model insulin sensitivity corresponded to 82% ± 19%, β-cell function to 221% ± 73%, and insulin resistance to 1.3 ± 0.3. After glucagon administration, rate of glucose production increased by 13.3 ± 8.3 µmol/kg per min and blood glucose by 1.4 ± 0.5 mmol/L. Glycerol production decreased from 12.8 ± 3.0 to 10.7 ± 2.9 µmol/kg per min. Mean insulin concentration increased from 10.9 ± 3.0 to 30.9 ± 10.3 mU/L. There was a strong inverse correlation between the decrease in lipolysis and increase in insulin after glucagon administration.

    CONCLUSIONS. Infants who are born large for gestational age show increased lipolysis and a propensity for decreased insulin sensitivity already at birth. The simultaneous increase in plasma insulin correlated strongly with the noted decrease in lipolysis, indicating an antilipolytic effect of insulin in these infants.

    Adipokines and their relation to maternal energy substrate production, insulin resistance and fetal size2013Ingår i: European Journal of Obstetrics, Gynecology, and Reproductive Biology, ISSN 0301-2115, E-ISSN 1872-7654, Vol. 168, nr 1, s. 26-29Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    OBJECTIVE:

    The role of adipokines in the regulation of energy substrate production in non-diabetic pregnant women has not been elucidated. We hypothesize that serum concentrations of adiponectin are related to fetal growth via maternal fat mass, insulin resistance and glucose production, and further, that serum levels of leptin are associated with lipolysis and that this also influences fetal growth. Hence, we investigated the relationship between adipokines, energy substrate production, insulin resistance, body composition and fetal weight in non-diabetic pregnant women in late gestation.

    STUDY DESIGN:

    Twenty pregnant women with normal glucose tolerance were investigated at 36 weeks of gestation at Uppsala University Hospital. Levels of adipokines were related to rates of glucose production and lipolysis, maternal body composition, insulin resistance, resting energy expenditure and estimated fetal weights. Rates of glucose production and lipolysis were estimated by stable isotope dilution technique.

    RESULTS:

    Median (range) rate of glucose production was 805 (653-1337)μmol/min and that of glycerol production, reflecting lipolysis, was 214 (110-576)μmol/min. HOMA insulin resistance averaged 1.5±0.75 and estimated fetal weights ranged between 2670 and 4175g (-0.2 to 2.7 SDS). Mean concentration of adiponectin was 7.2±2.5mg/L and median level of leptin was 47.1 (9.9-58.0)μg/L. Adiponectin concentrations (7.2±2.5mg/L) correlated inversely with maternal fat mass, insulin resistance, glucose production and fetal weight, r=-0.50, p<0.035, r=-0.77, p<0.001, r=-0.67, p<0.002, and r=-0.51, p<0.032, respectively. Leptin concentrations correlated with maternal fat mass and insulin resistance, r=0.76, p<0.001 and r=0.73, p<0.001, respectively. There was no correlation between maternal levels of leptin and rate of glucose production or fetal weight. Neither were any correlations found between levels of leptin or adiponectin and maternal lipolysis or resting energy expenditure.

    CONCLUSION:

    The inverse correlations between levels of maternal adiponectin and insulin resistance as well as endogenous glucose production rates indicate that low levels of adiponectin in obese pregnant women may represent one mechanism behind increased fetal size. Maternal levels of leptin are linked to maternal fat mass and its metabolic consequences, but the data indicate that leptin lacks a regulatory role with regard to maternal lipolysis in late pregnancy.

    Insulin Resistance, a Link between Maternal Overweight and Fetal Macrosomia in Nondiabetic Pregnancies2010Ingår i: Hormone research in paediatrics, ISSN 1663-2818, Vol. 74, nr 4, s. 267-274Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background/Aims: During the last decades the number of large for gestational age infants delivered by nondiabetic mothers has increased. Our aim was to investigate to what extent fetal growth in nondiabetic pregnant women can be explained by rates of maternal energy substrate production and resting energy expenditure. Methods: Twenty nonsmoking pregnant women without impaired glucose tolerance and with a wide range of fetal weights (0.2-2.7 SDS) were investigated at 36 weeks of gestation. Maternal lipolysis, glucose production, resting energy expenditure, body composition and insulin resistance were assessed.Results: Median (range) glucose production rate was 805 (653-1,337) mumol/min and that of glycerol, reflecting lipolysis, was 214 (110-576) mumol/min. Multiple linear regression analysis showed that maternal fat mass explained 36% of the variation in insulin resistance, accounting for 62% of the variation in glucose production. Further, glucose production explained 31% of the variation in fetal weight. Resting energy expenditure explained 51% of the variation in estimated fetal weight. Conclusion: Fetal weight is dependent on maternal glucose production, which is in turn determined by the degree of insulin resistance, induced in part by the maternal fat mass. The variation in maternal resting energy expenditure is closely related to fetal weight.

    Females born large for gestational age have a doubled risk of giving birth to large for gestational age infants2007Ingår i: Acta Paediatrica, ISSN 0803-5253, E-ISSN 1651-2227, Vol. 96, nr 3, s. 358-362Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Aim: To analyse if females born large for gestational age (LGA) have an increased risk to give birth to LGA infants and to study anthropometric characteristics in macrosomic infants of females born LGA.Methods: The investigation was performed as an intergenerational retrospective study of women born between 1973 and 1983, who delivered their first infant between 1989 and 1999. Birth characteristics of 47 783 females, included in the Swedish Birth Register both as newborns and mothers were analysed. LGA was defined as >2 SD in either birth weight or length for gestational age. The infants were divided into three subgroups: born tall only, born heavy only and born both tall and heavy for gestational age. Multiple logistic and linear regression analyses were performed.Results: Females, born LGA with regard to length or weight, had a two-fold (adjusted OR 1.96, 95% Cl 1.54-2.48) increased risk to give birth to an LGA infant. Females, born LGA concerning weight only, had a 2.6 (adjusted OR 2.63, 95%, 1.85-3.75) fold increased risk of having an LGA offspring heavy only and no elevated risk of giving birth to an offspring that was tall only, compared to females born not LGA. In addition, maternal obesity was associated with a 2.5 (adjusted OR 2.56, 95%, 2.20-2.98) fold increased risk of having an LGA newborn, compared to mothers with normal weight.Conclusion: Females, born LGA, have an increased risk to give birth to LGA infants, compared to mothers born not LGA. Maternal overweight increases this risk even further.

    School performance after preterm birth2015Ingår i: Epidemiology, ISSN 1044-3983, E-ISSN 1531-5487, Vol. 26, nr 1, s. 106-111Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BACKGROUND: An increased risk of poor school performance for children born preterm has been shown in many studies, but whether this increase is attributable to preterm birth per se or to other factors associated with preterm birth has not been resolved. METHODS: We used data from the Swedish Medical Birth Register, the Longitudinal Integration Database for Sickness Insurance and Labor Market Study, the Swedish Multigeneration Register, and the National School Register to link records comprising the Swedish birth cohorts from 1974 through 1991. Linear regression was used to assess the association between gestational duration and school performance, both with and without controlling for parental and socioeconomic factors. In a restricted analysis, we compared siblings only with each other. RESULTS: Preterm birth was strongly and negatively correlated with school performance. The distribution of school grades for children born at 31-33 weeks was on average 3.85 (95% confidence interval = -4.36 to -3.35) centiles lower than for children born at 40 weeks. For births at 22-24 weeks, the corresponding figure was -23.15 (-30.32 to -15.97). When taking confounders into account, the association remained. When restricting the analysis to siblings, however, the association between school performance and preterm birth after week 30 vanished completely, whereas it remained, less pronounced, for preterm birth before 30 weeks of gestation. CONCLUSIONS: Our study suggests that the association between school performance and preterm birth after 30 gestational weeks is attributable to factors other than preterm birth per se.

    Gestational diabetes and offspring body disproportion2010Ingår i: Acta Paediatrica, ISSN 0803-5253, E-ISSN 1651-2227, Vol. 99, nr 1, s. 89-93Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Aim:   It has been demonstrated that females born large for gestational age   (LGA) in weight but not length are at increased risk of being obese at   childbearing age. We addressed the question whether women with   gestational diabetes mellitus (GDM) are at increased risk of giving   birth to such infants.   Methods:   Birth characteristics of 884 267 infants of non-diabetic mothers and   7817 of mothers with GDM were analysed. LGA was defined as birth weight   or birth length > 2 standard deviation scores for gestational age.   Multiple logistic regression analysis was performed.   Results:   The odds ratio (OR) for a woman with GDM to give birth to an LGA infant   that was heavy alone was four times increased (OR: 3.71, 95% CI:   3.41-4.04). Furthermore, in the population of mothers giving birth to   LGA infants, the proportion heavy alone was 68% in the group of women   with GDM compared with 64.4% in the group of non-diabetic women. The   risks were independent of gender of the foetus.   Conclusion:   Women with GDM have an almost four times higher risk of delivering an   LGA infant that is heavy alone. The noted disproportion between weight   and length in infants of such mothers may have an impact on the risk of   later obesity.

    Dorsal Rhizotomy for Spasticity Management in Cerbral Palsy2018Ingår i: Cerebral Palsy / [ed] F. Miller et al, Springer International Publishing AG , 2018, s. 1-10Kapitel i bok, del av antologi (Refereegranskat)
    Abstract [en]

    Selective dorsal rhizotomy (SDR) is a neurosurgical procedure for the relief of spasticity interfering with motor function in children with spastic cerebral palsy (CP). The goal of the treatment is to improve function as well as reduce pain and discomfort related to severely increased spasticity. SDR is an ablative procedure that results in lifelong effects on function in the central nervous system. One must also be aware that performing SDR does not guarantee that other treatments for spasticity or orthopedic corrective procedures can be avoided. For SDR to be an effective treatment, it must be combined with specific physiotherapy over a long period of time. Today there exists a good body of evidence that SDR is an effective means of treating patients with the CP subtype spastic diplegia, as long as selection criteria are rigorously adhered to. The procedure is also safe with little risk of short or long-term complications. Further studies on long-term effects late in adulthood will show if the treatment effects are stable over time.

    Vascularization of the continuous human colonic cancer cell line LS 174 T deposited subcutaneously in nude rats1988Ingår i: Acta Pathologica, Microbiologica et Immunologica Scandinavica (APMIS), ISSN 0903-4641, E-ISSN 1600-0463, Vol. 96, nr 8, s. 701-710Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The macro- and microvasculature of the human colonic cancer cell line LS 174 T, 2-8 weeks after subcutaneous deposition in both hind legs of congenitally athymic rats was investigated by light microscopy, angiography, and microvascular corrosion casting with analysis in a scanning electron microscope. The tumour blood vessels were connected to branches of the femoral artery. Only the outer 200-500 micron of the tumour was extensively vascularized, with several concentric, incomplete layers of tortuous vessels, resembling onion skin. Light microscopy revealed necrosis and bleeding in the centre of the tumour, especially in the older tumours, which corresponded well to the central avascularity observed in the casts. There was an increase in venular and capillary density and tortousity towards the tumour in the adjacent muscular fascia. It is concluded that the cell line LS 174 T grows invasively inwards and recruits its vessels from the nude rat host. The overall tumour vascular pattern was unorganized, suggesting limited control of new vessel formation. Extravasations of resin, which were encountered in all cast tumours, can be a rough indicator of enhanced vascular permeability.

    Barnmorskors erfarenheter av att stödja och bemöta förstföderskor med förlossningsrädsla2018Självständigt arbete på avancerad nivå (magisterexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [sv]

    Bakgrund: Förlossningsrädsla hos gravida kvinnor som väntar sitt första barn påverkar både den blivande modern och det ofödda barnet. Det är därför viktigt att barnmorskan i mödravården kan uppmärksamma rädsla inför förlossningen i tid för att kunna hjälpa kvinnan på bästa sätt. Förlossningsrädsla är ett ökande problem som kan leda till fler komplicerade förlossningar och kejsarsnitt, vilket även kostar samhället mer pengar.

     

    Syfte: Syftet med denna studie var att belysa barnmorskors erfarenheter av att stödja och bemöta förstföderskor med förlossningsrädsla under graviditet samt studera vad som gett upphov till rädslan.

     

    Metod: Arbetet innehåller en kvalitativ design som baseras på individuella semi-strukturerade intervjuer med 11 barnmorskor inom mödravården i mellansverige. Datan har analyserats genom kvalitativ innehållsanalys och manifest metod.

     

    Resultat: Resultatet visade på fyra kategorier: Olika sätt att kommunicera rädsla, rädslans innehåll, inverkande faktorer samt att hjälpa och stötta kvinnor med förlossningsrädsla. Tretton subkategorier skapades och utgjorde kategorierna: Uttrycker rädslan med ord, sluter sig, katastroftankar, kontrollförlust, smärta, komplikationer, tidigare erfarenheter, övergrepp, psykisk ohälsa, yttre påverkan, svårt att nå kvinnan, en utmaning och stärka kvinnans självförtroende.

     

    Slutsats: De flesta förstföderskor uttrycker sin förlossningsrädsla tidigt i graviditeten men det är inte alla som vågar prata om den. Att tappa kontrollen beskrivs vara det främsta motivet till rädslan. Den vanligaste bidragande faktorn till förlossningsrädsla idag beror på yttre faktorer så som media och influenser från vänner och familj. Även dagens pressade förlossningssituation påverkar kvinnornas rädsla inför förlossningen. Det kan upplevas vara en utmaning att kunna stödja och bemöta kvinnan på bästa sätt.

    Arsenic-Associated Oxidative stress, Inflammation, and Immune Disruption in Human Placenta and Cord Blood2011Ingår i: Journal of Environmental Health Perspectives, ISSN 0091-6765, E-ISSN 1552-9924, Vol. 119, nr 2, s. 258-264Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BACKGROUND: Arsenic (As) exposure during pregnancy induces oxidative stress and increases the risk of fetal loss and low birth weight. OBJECTIVES: This study aimed to elucidate the effects of As exposure on immune markers in the placenta and cord blood, and the involvement of oxidative stress. METHODS: Pregnant women were enrolled around gestational week (GW) 8 in our longitudinal, population-based, mother-child cohort in Matlab, an area in rural Bangladesh with large variations in As concentrations in well water. Women (n=130) delivering at local clinics were included in the present study. We collected maternal urine twice during pregnancy (GW8 and 30) for measurements of As, and placenta and cord blood at delivery for assessment of immune and inflammatory markers. Placental markers were measured by immunohistochemistry and cord blood cytokines by multiplex cytokine assay. RESULTS: In multivariable adjusted models, maternal urinary As (U-As) exposure both at GW8 and 30 was significantly positively associated with placental markers of 8-oxoguanine (8-oxoG) and IL-1β, U-As at GW8 with TNF- α and IFN-γ, U-As at GW30 with leptin , and U-As at GW8 was inversely associated with CD3-T cells in the placenta. Cord blood cytokines (IL-1β, IL-8, IFN-γ, TNF-α) showed a U-shaped association with U-As at GW30. Placental 8-oxoG was significantly positively associated with placental pro-inflammatory cytokines. Multivariable adjusted analyses suggested that enhanced placental cytokine expression (TNF-α and IFN-γ) was primarily influenced by oxidative stress, while leptin expression appeared to be mostly mediated by As, and IL-1β appeared to be influenced by both oxidative stress and As. CONCLUSION: As exposure during pregnancy appeared to enhance placental inflammatory responses (in part by increasing oxidative stress), reduce placental T cells, and alter cord blood cytokines. These findings suggest that effects of As on immune function may contribute to impaired fetal and infant health.

    Arsenic Exposure Affects Plasma Insulin-Like Growth Factor 1 (IGF-1) in Children in Rural Bangladesh2013Ingår i: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 8, nr 11, s. e81530-Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Exposure to inorganic arsenic (As) through drinking water during pregnancy is associated with lower birth size and child growth. The aim of the study was to assess the effects of As exposure on child growth parameters to evaluate causal associations. Methodology/Findings: Children born in a longitudinal mother-child cohort in rural Bangladesh were studied at 4.5 years (n=640) as well as at birth (n=134). Exposure to arsenic was assessed by concurrent and prenatal (maternal) urinary concentrations of arsenic metabolites (U-As). Associations with plasma concentrations of insulin-like growth factor 1 (IGF-1), calcium (Ca), vitamin D (Vit-D), bone-specific alkaline phosphatase (B-ALP), intact parathyroid hormone (iPTH), and phosphate (PO4) were evaluated by linear regression analysis, adjusted for socioeconomic factor, parity and child sex. Child U-As (per 10 mu g/L) was significantly inversely associated with concurrent plasma IGF-1 (beta=-0.27; 95% confidence interval: -0.50, -0.0042) at 4.5 years. The effect was more obvious in girls (beta=-0.29; -0.59, 0.021) than in boys, and particularly in girls with adequate height (beta=-0.491; -0.97, -0.02) or weight (beta=-0.47; 0.97, 0.01). Maternal U-As was inversely associated with child IGF-1 at birth (r=-0.254, P=0.003), but not at 4.5 years. There was a tendency of positive association between U-As and plasma PO4 in stunted boys (beta=0.27; 0.089, 0.46). When stratified by % monomethylarsonic acid (MMA, arsenic metabolite) (median split at 9.7%), a much stronger inverse association between U-As and IGF-1 in the girls (beta=-0.41; -0.77, -0.03) was obtained above the median split. Conclusion: The results suggest that As-related growth impairment in children is mediated, at least partly, through suppressed IGF-1 levels.

    Antenatal care for Somali-born women in Sweden: Perspectives from mothers, fathers and midwives2019Ingår i: Midwifery, ISSN 0266-6138, E-ISSN 1532-3099, Vol. 74, s. 107-115Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objective:

    To explore Somali-born parents' experiences of antenatal care in Sweden, antenatal care midwives' experiences of caring for Somali-born parents, and their respective ideas about group antenatal care for Somali-born parents.

    Design:

    Eight focus group discussions with 2-8 participants in each were conducted, three with Somaliborn mothers, two with fathers and three with antenatal care midwives. The transcribed text was analysed using Attride-Stirling's tool "Thematic networks".

    Setting:

    Two towns in mid-Sweden and a suburb of the capital city of Sweden. Participants: Mothers (n = 16), fathers (n = 13) and midwives (n = 7) were recruited using purposeful sampling.

    Findings:

    Somali-born mothers and fathers in Sweden were content with many aspects of antenatal care, but they also faced barriers. Challenges in the midwife-parent encounter related to tailoring of care to individual needs, dealing with stereotypes, addressing varied levels of health literacy, overcoming communication barriers and enabling partner involvement. Health system challenges related to accessibility of care, limited resources, and the need for clear, but flexible routines and supportive structures for parent education. Midwives confirmed these challenges and tried to address them but sometimes lacked the support, resources and tools to do so. Mothers, fathers and midwives thought that language-supported group antenatal care might help to improve communication, provide mutual support and enable better dialogue, but they were concerned that group care should still allow privacy when needed and not stereotype families according to their country of birth.

    Key conclusions:

    ANC interventions targeting inequalities between migrants and non-migrants may benefit from embracing a person-centred approach, as a means to counteract stereotypes, misunderstandings and prejudice. Group antenatal care has the potential to provide a platform for person-centred care and has other potential benefits in providing high-quality antenatal care for sub-groups that tend to receive less or poor quality care. Further research on how to address stereotypes and implicit bias in maternity care in the Swedish context is needed. (c) 2019 The Authors. Published by Elsevier Ltd.

    Association of self-reported different aspects of workplace environment and general wellbeing with maximum workload – A cross- sectional study2018Självständigt arbete på avancerad nivå (masterexamen), 80 poäng / 120 hpStudentuppsats (Examensarbete)
    Abstract [en]

    Introduction

    Cardiovascular disease (CVD) is the leading cause of death globally and similarly in United Kingdom (UK), accounting for 31% and 45% annual deaths respectively. Workplace environment consists of different elements (e.g.- physical and psychosocial environment, intra and extra organizational settings) and interrelationship of employer and employee, playing an important role on workers’ health. Current study aims to identify the association of different aspects of workplace environment and general wellbeing with maximum workload (MW) in a working population in UK.

    Method

    A cross-sectional study has been done including a total of 77,781 working people aged 39 to 72 years old who participated voluntarily in the UK Biobank baseline assessment cohort study. Exposures were selfreported that included information about both physical and psychosocial aspects of workplace environment and general well-being. The outcome variable was maximum workload calculated during electrocardiogram (ECG) stress test. Three different statistical models were tested through ordinal logistic regressions using the SPSS software.

    Results

    No/low health satisfaction was associated with reduction in maximum workload and this association was constant in all analytical model, both in crude (B -0.786, 95% CI -0.825, -0.748) and adjusted models (B -0.866, 95% CI -0.910, -0.823). Other variables regarding different aspects of workplace environment and well-being showed no statistically significant result on the adjusted models.

    Conclusion

    Health satisfaction may be considered as an important determinant of CVD among middle and old-aged working population. Future research required to establish the result and to formulate preventive measures in workplace for better health outcome of workers.

    Lactate distribution in culture medium of human myometrial biopsies incubated under different conditions2009Ingår i: American Journal of Physiology. Endocrinology and Metabolism, ISSN 0193-1849, E-ISSN 1522-1555, Vol. 297, nr 6, s. E1414-E1419Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    It is generally believed that a relationship exists between muscle fatigue and intracellular accumulation of lactate. This reasoning is relevant to obstetrical issues. Myocytes in uterus work together during labor, and the contractions need to be strong and synchronized for a child to be delivered. At labor dystocia, the progress of labor becomes slow or arrested after a normal beginning. It has been described that, during labor dystocia, when the force of the contractions is low, the uterus is under hypoxia, and anaerobic conditions with high levels of lactate in amniotic fluid dominate. The purpose of this study was to examine whether myometrial cells are involved in the production of lactate in amniotic fluid and whether there are differences in production and distribution of lactate in cells incubated under aerobic and anaerobic conditions. We also wanted to elucidate the involvement of specific membrane-bound lactate carriers. Women undergoing elective caesarean section were included. Myometrial biopsies from uteri were collected and subjected to either immunohistochemistry to identify lactate carriers or in vitro experiments to analyze production of lactate. The presence of lactate carriers named monocarboxylate transporters 1 and 4 was verified. Myometrial cells produced lactate extracellularly, and the lactate carriers operated differently under anaerobic and aerobic conditions; while being mainly unidirectional under anaerobic conditions, they became bidirectional under aerobic conditions. Human myometrial cells produced and delivered lactate to the extracellular medium under both anaerobic and aerobic conditions. The delivery was mediated by lactate carriers.

    Carotid Artery Wall Layer Dimensions during and after Pre-eclampsia: An investigation using non-invasive high-frequency ultrasound2013Doktorsavhandling, sammanläggning (Övrigt vetenskapligt)
    Abstract [en]

    Pre-eclampsia is associated with increased risk of cardiovascular disease (CVD) later in life. The ‘gold standard’ for estimating cardiovascular risk - ultrasound assessment of the common carotid artery intima-media thickness (CCA-IMT) - does not convincingly demonstrate this increased risk. The aim of this thesis was to examine whether high-frequency (22 MHz) ultrasound assessment of the individual CCA intima and media layers and calculation of the intima/media (I/M) ratio - can indicate the increased cardiovascular risk after pre-eclampsia. After validation of the method in premenopausal women with systemic lupus erythematosus (SLE) who have a recognized increased risk of CVD, women during and after normal and preeclamptic pregnancies were investigated.

    Assessment of the individual artery wall layers reliably demonstrated the increased cardiovascular risk in premenopausal women with SLE, while CCA-IMT did not. The artery wall layer dimensions in women with SLE were comparable to those of postmenopausal women without SLE and were 30 years older.

    Among the women with normal pregnancies negative changes to the artery wall later on in the pregnancy were seen in those with lower serum estradiol, older age, higher body mass index or higher blood pressure early in the pregnancy. About one year postpartum, both the mean intima thickness and the I/M ratio had improved, compared to values during pregnancy. These findings support the theory that normal pregnancy is a stress on the vascular system.

    Women who developed pre-eclampsia (mean age 31 years) had thicker intima layers, thinner media layers and higher I/M ratios, both at diagnosis and one year postpartum, than women with normal pregnancies, indicating increased cardiovascular risk.

    Women with a history of severe pre-eclampsia (mean age 44 years; mean 11 years since the last delivery) had thicker intima layers and higher I/M ratios than women with a history of normal pregnancies, indicating long-standing negative vascular effects.

    Assessment of individual CCA wall layers, but not of CCA-IMT, provided clear evidence of the well-known increased cardiovascular risk in women with SLE or pre-eclampsia. The method has the potential to become an important tool in reducing cardiovascular morbidity and mortality in these women through early diagnosis and intervention.

    Sub-clinical atherosclerosis in the common carotid artery in women with/without previous pre-eclampsia: A seven-year follow-up.2019Ingår i: Atherosclerosis, ISSN 0021-9150, E-ISSN 1879-1484, artikel-id S0021-9150(19)30449-6Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BACKGROUND AND AIMS: Pre-eclampsia is associated with increased risk of cardiovascular disease and premature death. However, conventional common carotid artery intima-media thickness (CCA-IMT) measurement does not reflect this. In contrast, measurement of the individual CCA intima and media thicknesses clearly indicates increased vascular risk both at diagnosis and about one year after pre-eclampsia. This study examined whether individual CCA wall layers, risk factors for cardiovascular disease, and markers of endothelial dysfunction had normalized or remained unfavorable seven years after pre-eclampsia.

    METHODS: The individual CCA intima and media thicknesses were measured using 22 MHz ultrasound. Conventional cardiovascular risk factors were recorded. A thick intima, thin media and high intima/media thickness ratio (I/M) are signs of sub-clinical atherosclerosis.

    RESULTS: The median age of women with previous pre-eclampsia (cases = 23) or normal pregnancies (controls = 35) was 39/37 years. At follow-up (median about seven years), the intima remained thicker and the I/M was higher in cases than in controls [all p < 0.0001; p < 0.001 after adjustment for time to follow-up, body mass index (BMI), and mean arterial pressure (MAP)], whereas the CCA-IMT was illogically thinner. Further, BMI, MAP, hip circumference, abdominal height, serum endostatin and apolipoprotein B levels were higher in cases (all p < 0.05). Intima and I/M measurements were correlated with age, MAP, endostatin and apolipoprotein B, whereas no logical correlations were found for CCA-IMT.

    CONCLUSIONS: The arteries in cases but not controls were still adversely affected after seven years. Measuring intima thickness and I/M appears preferable to measuring CCA-IMT for demonstrating vascular risk after pre-eclampsia.

    Artery Wall Layer Dimensions during Normal Pregnancy: A longitudinal study using non-invasive high-frequency ultrasound2013Ingår i: American Journal of Physiology. Heart and Circulatory Physiology, ISSN 0363-6135, E-ISSN 1522-1539, Vol. 304, nr 2, s. H229-H234Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The vascular effects of normal pregnancy were investigated by estimating the intima and media thicknesses of the common carotid artery separately using 22MHz ultrasound (Collagenoson, Meudt, Germany) in 57 healthy women with normal pregnancies and pregnancy outcomes, in all three trimesters and at one year postpartum. A thick intima, thin media and high intima/media (I/M) ratio are signs of a less healthy artery wall. The mean artery wall layer dimensions remained fairly constant during pregnancy but the intima thickness and I/M thickness ratio appeared to improve (decrease) postpartum (p<0.001 for both). The cardiovascular risk parameters age, body mass index (BMI), and blood pressure in the first trimester were associated with higher I/M ratios, especially in the second trimester, whereas higher serum estradiol levels were significantly associated with a lower I/M ratio. Changes from the first to second trimesters in I/M ratio, taking into account differential changes in intima and media thickness, were significantly (p<0.05-0.001) associated with all risk parameters tested except age, which was associated with increased intima thickness (p=0.02). Associations with third trimester values and changes from first to third trimesters were similar but less apparent. Thus, fairly constant mean artery wall layer dimensions during pregnancy appeared to improve postpartum. However, higher age, BMI or blood pressure, and lower serum estradiol levels in the first trimester appeared to negatively affect the artery wall, strongly suggesting that pregnancy has negative vascular effects in some women. A less likely explanation involves possible adaptation to physiological changes during and after pregnancy.

    Individual Artery Wall Layer Dimensions Indicate Increased Cardiovascular Risk in Previous Severe Preeclampsia: An investigation using non-invasive high-frequency ultrasound2013Ingår i: Hypertension, ISSN 0194-911X, E-ISSN 1524-4563Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Preeclampsia, especially severe preeclampsia, is associated with an increased risk of cardiovascular disease later in life. However, ultrasound assessments of the common carotid artery intima-media thickness (CCA-IMT) do not convincingly demonstrate this. The aim of this study was to assess whether the individual thickness of the CCA intima and media layers and calculation of intima/media (I/M) ratio indicate an increased cardiovascular risk in women with previous severe PE. The thicknesses of the CCA intima and media layers were obtained by non-invasive high-frequency ultrasound (22 MHz) (Collagenoson, Meudt, Germany) in 42 women with previous severe preeclampsia and 44 women with previous normal pregnancies. A thick intima, thin media and high I/M ratio are signs of a less healthy artery wall. Women with previous severe preeclampsia had a thicker mean CCA intima and a higher I/M ratio than women with previous normal pregnancies (both p < 0.0001). CCA-IMT did not differ significantly between the groups. In receiver operating characteristic (ROC) curve analysis, both intima thickness and I/M ratio clearly discriminated between women with and without previous severe preeclampsia [area under the curve (AUC) about 0.95], whereas CCA-IMT did not (AUC 0.52). Estimation of the individual CCA intima and media layers using high-frequency ultrasound and calculation of the I/M ratio clearly demonstrated the well known increased cardiovascular risk in women with previous severe preeclampsia, whereas CCA-IMT did not. This method appears preferable to measuring CCA-IMT for imaging arterial effects and the increased cardiovascular risk in women with a history of previous severe preeclampsia.

    Changes in the Artery Wall Layer Dimensions in Women with Preeclampsia: an investigation using non-invasive high frequency ultrasound2012Ingår i: Acta Obstetricia et Gynecologica Scandinavica, ISSN 0001-6349, E-ISSN 1600-0412, Vol. 91, nr S159, s. 28-28Artikel i tidskrift (Övrigt vetenskapligt)
    Abstract [en]

    Background:

    Preeclampsia (PE) is associated with increased risk for cardiovascular disease later in life. Whether, the artery wall layer dimensions differ between PE and normal pregnancy is unclear. The aim of this study was to estimate if women with PE have different common carotid artery wall layer dimensions than women with normal pregnancy, both during pregnancy and about one year postpartum.

    Methods:

    By using high-frequency (22MHz) ultrasound (Collagenoson, Meudt, Germany) separate estimates of the common carotid artery intima and media layers were obtained and the I/M ratio was calculated in women with PE (n=55 during pregnancy and n=48 at postpartum) and with normal pregnancy (n=65 during pregnancy and n=59 at postpartum). Thick intima, thin media and a high intima/media ratio are signs of less healthy artery wall and vice versa.

    Results:

    In women with PE, the intima was thicker (0.18 } 0.03 vs. 0.11 } 0.02; p < .001), the media was thinner (0.47 } 0.12 vs. 0.55 } 0.14; p = .001) and the I/M ratio was higher (0.41 } 0.14 vs. 0.20 } 0.05; p < .001) compared to women with normal pregnancy. Further, for changes from pregnancy to postpartum, both for PE and normal pregnancy, the intima and the I/M ratio had improved but still significantly higher in women with PE than in women with normal pregnancy.

    Conclusion:

    In women with PE, we found a thicker intima, thinner media and a higher I/M ratio compared to women with normal pregnancy, indicating a more negatively affected artery wall layer dimensions. Persisting negative effects of PE on artery wall at postpartum, despite improvement of artery wall layers compared to values during pregnancy, indicates a permanent damage of the vascular system in this group of women.

    Association between angiogenic factors and signs of arterial aging in women with pre-eclampsia2017Ingår i: Ultrasound in Obstetrics and Gynecology, ISSN 0960-7692, E-ISSN 1469-0705, Vol. 50, s. 93-99Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    OBJECTIVES: Pre-eclampsia (PE) is associated with an increased risk of cardiovascular disease (CVD) later in life. In PE there is a substantial increase in levels of the anti-angiogenic factor soluble fms-like tyrosine kinase-1 (sFlt1) and decreased levels of the pro-angiogenic factor placental growth factor (PlGF). Elevated levels of sFlt1 are also found in individuals with CVD. The aims of this study were to assess sFlt1, PlGF and the sFlt1/PlGF ratio and their correlation with signs of arterial aging by measuring common carotid artery (CCA) intima and media thicknesses and their ratio (I/M ratio) in women with and without PE.

    METHODS: Serum sFlt1 and PlGF levels were measured using commercially available enzyme-linked immunosorbent assay kits, and CCA intima and media thicknesses were estimated using high-frequency (22 MHz) ultrasonography in 55 women at PE diagnosis and 64 women with normal pregnancies at a similar gestational age, with reassessment one year postpartum. A thick intima, thin media and a high I/M ratio indicate a less healthy arterial wall.

    RESULTS: During pregnancy, higher levels of sFlt1, lower levels of PlGF and thicker intima, thinner media and higher I/M ratios were found in women with PE vs. controls (all p < 0.0001). Further, sFlt1 and the sFlt1/PlGF ratio were positively correlated with intima thickness and I/M ratio (all p < 0.0001), but negatively correlated with media thickness (p = 0.002 and 0.03, respectively). About one year postpartum, levels of sFlt1 and the sFlt1/PlGF ratio had decreased in both groups, but compared with controls women in the PE group still had higher levels (p = 0.001 and 0.02, respectively). Further, sFlt1 levels and the sFlt1/PlGF ratio were still positively correlated with intima thickness and I/M ratio.

    CONCLUSIONS: Higher sFlt1 levels and sFlt1/PlGF ratios in women with PE were positively associated with signs of arterial aging during pregnancy. About one year postpartum sFlt1 levels and the sFlt1/PlGF ratios were still higher in the PE group, and also associated with the degree of arterial aging.

    Serum Pentraxin 3 is associated with signs of arterial alteration in women with preeclampsia.2017Ingår i: International Journal of Cardiology, ISSN 0167-5273, E-ISSN 1874-1754, Vol. 241, s. 417-422Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BACKGROUND: Preeclampsia (PE) in pregnancy is a state of exaggerated inflammation and is associated with an increased risk of cardiovascular disease (CVD) later in life. Levels of pentraxin 3 (PTX3), a novel inflammation marker, are increased during PE and in individuals with CVD. The primary aim of this study was to assess whether serum PTX3 in women with PE is associated with adverse arterial effects; a thicker intima and higher intima/media (I/M) ratio in the common carotid artery (CCA).

    METHODS: Serum PTX3 levels were measured using commercially available enzyme-linked immunosorbent assay kits, and individual CCA intima and media thicknesses were estimated by 22MHz non-invasive ultrasound in 55 women at PE diagnosis and 64 women with normal pregnancies at a similar gestational age, and about one year postpartum. A thick intima, thin media and high I/M ratio indicate a less healthy artery wall.

    RESULTS: During pregnancy serum PTX3 correlated positively with intima thickness and I/M ratio but negatively with media thickness (all p<0.0001), indicating adverse arterial effects. About one year postpartum, PTX3 levels had decreased in both groups and there remained no significant group difference or significant correlation with CCA wall layers.

    CONCLUSIONS: Higher levels of serum PTX3 in women with PE were significantly associated with signs of adverse arterial effects during pregnancy, but not one year postpartum, supporting the rapid dynamics of PTX3.

    Individual Common Carotid Artery Wall Layer Dimensions, but Not Carotid Intima-Media Thickness, Indicate Increased Cardiovascular Risk in Women With Preeclampsia: An investigation using non-invasive high-frequency ultrasound2013Ingår i: Circulation Cardiovascular Imaging, ISSN 1941-9651, E-ISSN 1942-0080, Vol. 6, nr 5, s. 762-768Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background Preeclampsia (PE) is associated with increased risk of cardiovascular disease later in life. Ultrasound assessment of the common carotid artery intima-media thickness (IMT) during or after PE has not indicated any increased cardiovascular risk. Methods and Results We used high-frequency ultrasound (22 MHz) to estimate the individual common carotid artery IMTs in 55 women at PE diagnosis and in 64 women with normal pregnancies at a similar stage. All were re-examined about 1 year postpartum. A thick intima, thin media, and high intima/media (I/M) ratio are signs of a less healthy artery wall. PE was associated with a significantly thicker mean common carotid artery intima, thinner media, and higher I/M ratio than in normal pregnancy (mean I/M difference, 0.21; 95% confidence interval, 0.17-0.25; P<0.0001). After adjustment for first trimester body mass index and mean arterial pressure, differences in intima thickness and I/M remained significant. About 1 year postpartum, these values had improved in both groups, but group differences remained significant (all adjusted P<0.0001). There were no significant differences in IMT between groups. In receiver-operating characteristic curve analysis, intima thickness and I/M were strongly predictive of prevalent PE (area under the curve, approximate to 0.95), whereas IMT was not (area under the curve, 0.49). Conclusions The arteries of women with PE were negatively affected during pregnancy and 1 year postpartum compared with women with normal pregnancies, indicating increased cardiovascular risk. Estimation of intima thickness and I/M ratio seem preferable to estimation of common carotid artery IMT in imaging cardiovascular risk in PE. Results from this pilot study warrant further confirmation.

    Incidence of Subclinical Hypothyroidism and Hypothyroidism in Early Pregnancy2017Ingår i: Journal of Women's Health, ISSN 1540-9996, E-ISSN 1931-843X, Vol. 26, nr 11, s. 1231-1235Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Untreated and subclinical hypothyroidism (SCH) has been associated with adverse pregnancy complications such as increased risk of miscarriage, hypertension, preeclampsia, and preterm delivery. However, in Sweden, screening for thyroid dysfunction during pregnancy is only recommended for women with a high risk of thyroid disease. Therefore, the aim of this study was to determine the incidence of clinical and SCH in women in the first trimester of pregnancy.

    Materials and Methods: In this prospective study, 1298 pregnant women were divided into three groups: one unselected general screening group (n=611), one low-risk group comprising women without risk factors for thyroid disorder (n=511), and one high-risk group comprising women with an inheritance or suspicion of thyroid disease or undergoing treatment for thyroid disease (n=88). Serum was obtained up to gestational week 13, and thyrotropin (TSH) was analyzed.

    Results: The incidences of thyroid dysfunction in the three screening groups were 9.8% in the general screening group, 9.6% in the low-risk group, and 10.2%, p=0.948, in the high-risk group. In the women with known hypothyroidism on levothyroxine treatment, 50.6% had serum TSH levels above 2.0mIU/L.

    Conclusions: High-risk screening is not useful in predicting which women are at risk of thyroid disease in early pregnancy since approximate to 10% of women with SCH or hypothyroidism could not be diagnosed in this way.

    Evaluation of ELISA and rapid test for the analysis of fecal Calprotectin2013Självständigt arbete på grundnivå (kandidatexamen), 10 poäng / 15 hpStudentuppsats (Examensarbete)
    Abstract [en]

    ABSTRACT

    Background Calprotectin is a protein found in the cytoplasm of neutrophile granulocytes. In the course of inflammatory bowel disease (IBD), calprotectin is released during chronic inflammation in the gut. Activation of neutrophils during the inflammation is followed by activation and secretion of pro-inflammatory molecules such as calprotectin. Calprotectin is stable in stool up to 7 days and can therefore be used as a non-invasive marker for diagnosis, treatment and measurement of the disease activity in patients with IBD. The most common method for analysis of calprotectin concentration is ELISA. This method is time-consuming and many manufactures have therefore developed rapid tests as a faster alternative for quantification of calprotectin in stool.

    Aim The aim of the study was to evaluate one ELISA and one rapid test from the same manufacture compare the data with the existing ELISA-method used in the laboratory for routine analysis.

    Methods A rapid test (CalFast) and an ELISA method (CalPrest) from Eurospital, were used for analysis of calprotectin in stool. These two methods were compared with known concentrations of calprotectin obtained by the ELISA method from Bühlmann used in the routine work. 

    Results The results showed poor correlation between the rapid test and the ELISA method. Furthermore, the comparison between the two ELISA-methods showed a poor correlation.

    Conclusion Evaluation of the two new methods showed poor correlation with the existing ELISA method from Bühlmann. Evaluation of the rapid test did not show any correlation with the two ELISA methods and the data cannot be trusted. It is difficult to conclude which of the two ELISA methods gives accurate results due to the absence of an international standard.

    Non-HLA gene polymorphisms in juvenile idiopathic arthritis: associations with disease outcome2017Ingår i: Scandinavian Journal of Rheumatology, ISSN 0300-9742, E-ISSN 1502-7732, Vol. 46, nr 5, s. 369-376Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objective: To test the hypothesis that non-HLA single-nucleotide polymorphisms (SNPs) associated with the risk of juvenile idiopathic arthritis (JIA) are risk factors for an unfavourable disease outcome at long-term follow-up.

    Methods: The Nordic JIA cohort is a prospective multicentre study cohort of patients from the Nordic countries. In all, 193 patients met the inclusion criteria of having an 8year follow-up assessment and available DNA sample. Seventeen SNPs met the inclusion criteria of having significant associations with JIA in at least two previous independent study cohorts. Clinical endpoints were disease remission, actively inflamed joints and joints with limitation of motion (LOM), articular or extra-articular damage, and history of uveitis.

    Results: Evidence of associations between genotypes and endpoints were found for STAT4, ADAD1-IL2-IL21, PTPN2, and VTCN1 (p=0.003-0.05). STAT4_rs7574865 TT was associated with the presence of actively inflamed joints [odds ratio (OR) 20.6, 95% confidence interval (CI) 2.2->100, p=0.003] and extra-articular damage (OR 7.9, 95% CI 1-56.6, p=0.057). ADAD1_rs17388568 AA was associated with a lower risk of having joints with LOM (OR 0.1, 95% CI 0-0.55, p=0.016). PTPN2_rs1893217 CC was associated with a lower risk of having joints with LOM (OR 0.2, 95% CI 0-0.99, p=0.026), while VTCN1_rs2358820 GA was associated with uveitis (OR 3.5, 95% CI 1-12.1, p=0.029).

    Conclusion: This exploratory study, using a prospectively followed JIA cohort, found significant associations between long-term outcome and SNPs, all previously associated with development of JIA and involved in immune regulation and signal transduction in immune cells.

    High-sensitive CRP as a predictive marker of long-term outcome in juvenile idiopathic arthritis2017Ingår i: Rheumatology International, ISSN 0172-8172, E-ISSN 1437-160X, Vol. 37, nr 5, s. 695-703Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    To evaluate whether C-reactive protein (CRP), including variation within the normal range, is predictive of long-term disease outcome in Juvenile Idiopathic Arthritis (JIA). Consecutive patients with newly diagnosed JIA were included prospectively from defined geographic areas of the Nordic countries from 1997 to 2000. Inclusion criteria were availability of a baseline serum sample within 12 months after disease onset and 8-year clinical assessment data. Systemic onset JIA was not included. CRP was measured by high-sensitive ELISA (detection limit of 0.2 mg/l). One hundred and thirty participants with a median follow-up time of 97 months (range 95-100) were included. At follow-up, 38% of the patients were in remission off medication. Absence of remission was associated with elevated level of CRP at baseline (odds ratio (OR) 1.33, confidence interval (CI) 1.08-1.63, p = 0.007). By applying a cutoff at the normal upper limit (> 10 mg/l), the risk of not achieving remission was increased to an OR of 8.60 (CI 2.98-24.81, p < 0.001). Variations of CRP within the normal range had no predictive impact on disease activity at follow-up. Baseline levels of ESR were available in 80 patients (61%) and elevated ESR was associated with absence of remission in a multivariable logistic regression analysis (OR 2.32, CI 1.35-4.00, p = 0.002). This results of this study indicate that baseline CRP concentrations above 10 mg/l are predictive of a poor outcome at 8-year follow-up. We could not demonstrate any predictive value of CRP variations within the normal range.

    Asparaginase treatment in infants with acute lymphoblastic leukemia; pharmacokinetics and asparaginase hypersensitivity in Interfant-062019Ingår i: Leukemia and Lymphoma, ISSN 1042-8194, E-ISSN 1029-2403, Vol. 60, nr 6, s. 1469-1475Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Acute lymphoblastic leukemia (ALL) is a rare disease in infants. Asparaginase is an essential part of the treatment, and there Acute is a need to evaluate the efficiency and safety of this drug in this age group. We evaluated the pharmacokinetics of intramuscularly administered native E. coli asparaginase (Asparaginase Medac((R))) and PEG-asparaginase (Oncaspar((R))) as well as hypersensitivity reactions during treatment in Interfant-06 (www.clinicaltrials.gov: NCT01025804). All patients without hypersensitivity had sufficiently high enzyme activity levels during treatment with both preparations. Patients with hypersensitivity reactions during treatment, characterized by the presence of either or not of clinical symptoms and no measurable enzyme activity, received ineffective therapy. For optimization of the bad prognosis in infant ALL, therapeutic drug monitoring should be performed for identification of patients who should be switched to a different asparaginase preparation because of inactivation of the drug.
