    Acute intermittent porphyria symptoms during the menstrual cycle2015Inngår i: Internal medicine journal (Print), ISSN 1444-0903, E-ISSN 1445-5994, Vol. 45, nr 7, 725-731 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Acute intermittent porphyria (AIP), a life-threatening form of the disease, is accompanied by several pain, mental and physical symptoms.

    Aims: In this study, we evaluated the cyclicity of AIP and premenstrual syndrome (PMS) symptoms in 32 women with DNA-diagnosed AIP during their menstrual cycles, in northern Sweden.

    Methods: The cyclicity of AIP symptoms and differences in them between the follicularand luteal phases, and the cyclicity of each symptom in each individual woman indifferent phases of her menstrual cycle were analysed with a prospective daily ratingquestionnaire. PMS symptoms were also evaluated in the patients on a daily rating scale.

    Results: Of the 32 women, 30 showed significant cyclicity in at least one AIP or PMS symptom (P < 0.05–0.001). Back pain (10/32) was the most frequent AIP pain symptomand sweet craving (10/15) was the most frequent PMS symptom. Pelvic pain (F = 4.823,P = 0.036), irritability (F = 7.399, P = 0.011), cheerfulness (F = 5.563, P = 0.025), sexualdesire (F = 8.298, P = 0.007), friendliness (F = 6.157, P = 0.019), breast tenderness (F =21.888, P = 0.000) and abdominal swelling (F = 16.982, P = 0.000) showed significantcyclicity. Pelvic pain and abdominal swelling (rs= 0.337, P < 0.001) showed the strongest correlation. The age of women with latent AIP was strongly correlated with abdominal swelling during the luteal phase (rs= 0.493, P < 0.01).

    Conclusion: Our results suggest that the symptoms of AIP patients change during their menstrual cycles.

    Intimate partner violence in urban Pakistan: prevalence, frequency, and risk factors2011Inngår i: International journal of women's health, ISSN 1179-1411, Vol. 3, 105-15 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Intimate partner violence (IPV) is an important public health issue with severe adverse consequences. Population-based data on IPV from Muslim societies are scarce, and Pakistan is no exception. This study was conducted among women residing in urban Karachi, to estimate the prevalence and frequency of different forms of IPV and their associations with sociodemographic factors.

    Methods: This cross-sectional community-based study was conducted using a structured questionnaire developed by the World Health Organisation for research on violence. Community midwives conducted face-to-face interviews with 759 married women aged 25–60 years.

    Results: Self-reported past-year and lifetime prevalence of physical violence was 56.3 and 57.6%, respectively; the corresponding figures for sexual violence were 53.4% and 54.5%, and for psychological abuse were 81.8% and 83.6%. Violent incidents were mostly reported to have occurred on more than three occasions during the lifetime. Risk factors for physical violence related mainly to the husband, his low educational attainment, unskilled worker status, and five or more family members living in one household. For sexual violence, the risk factors were the respondent’s low educational attainment, low socioeconomic status of the family, and five or more family members in one household. For psychological violence, the risk factors were the husband being an unskilled worker and low socioeconomic status of the family.

    Conclusion: Repeated violence perpetrated by a husband towards his wife is an extremely common phenomenon in Karachi, Pakistan. Indifference to this type of violence against women stems from the attitude that IPV is a private matter, usually considered a justifiable response to misbehavior on the part of the wife. These findings point to serious violations of women’s rights and require the immediate attention of health professionals and policymakers.

    Gender roles and their influence on life prospects for women in urban Karachi, Pakistan: a qualitative study2011Inngår i: Global health action, ISSN 1654-9880, Vol. 4, 7448- s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Pakistan is a patriarchal society where men are the primary authority figures and women are subordinate. This has serious implications on women’s and men’s life prospects.

    Objective: The aim was to explore current gender roles in urban Pakistan, how these are reproduced and maintained and influence men’s and women’s life circumstances.

    Design: Five focus group discussions were conducted, including 28 women representing employed, unemployed, educated and uneducated women from different socio-economic strata. Manifest and latent content analyses were applied.

    Findings: Two major themes emerged during analysis: ‘Reiteration of gender roles’ and ‘Agents of change’. The first theme included perceptions of traditional gender roles and how these preserve women’s subordination. The power gradient, with men holding a superior position in relation to women, distinctive features in the culture and the role of the extended family were considered to interact to suppress women. The second theme included agents of change, where the role of education was prominent as well as the role of mass media. It was further emphasised that the younger generation was more positive to modernisation of gender roles than the elder generation.

    Conclusions: This study reveals serious gender inequalities and human rights violations against women in the Pakistani society. The unequal gender roles were perceived as static and enforced by structures imbedded in society. Women routinely faced serious restrictions and limitations of autonomy. However, attainment of higher levels of education especially not only for women but also for men was viewed as an agent towards change. Furthermore, mass media was perceived as having a positive role to play in supporting women’s empowerment.

    Violence permeating daily life: a qualitative study investigating perspectives on violence among women in Karachi, Pakistan2012Inngår i: International Journal of Women's Health, ISSN 1179-1411, Vol. 4, 577-585 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: This study explored how married women perceive situations which create family conflicts and lead to different forms of violence in urban Pakistan. In addition, it examines perceptions of consequences of violence, their adverse health effects, and how women resist violence within marital life.

    METHODS: Five focus group discussions were conducted with 28 women in Karachi. Purposive sampling, aiming for variety in age, employment status, education, and socioeconomic status, was employed. The focus group discussions were conducted in Urdu and translated into English. Manifest and latent content analysis were applied.

    RESULTS: One major theme emerged during the analysis, ie, family violence through the eyes of females. This theme was subdivided into three main categories. The first category, ie, situations provoking violence and their manifestations, elaborates on circumstances that provoke violence and situations that sustain violence. The second category, ie, actions and reactions to exposure to violence, describes consequences of ongoing violence within the family, including those that result in suicidal thoughts and actions. The final category, ie, resisting violence, describes how violence is avoided through women's awareness and actions.

    CONCLUSION: The current study highlights how female victims of abuse are trapped in a society where violence from a partner and family members is viewed as acceptable, where divorce is unavailable to the majority, and where societal support of women is limited. There is an urgent need to raise the subject of violence against women and tackle this human rights problem at all levels of society by targeting the individual, family, community, and societal levels concurrently.

    Intimate partner violence and mental health effects: a population-based study among married women in Karachi, Pakistan2013Inngår i: International Journal of Behavioral Medicine, ISSN 1070-5503, E-ISSN 1532-7558, Vol. 20, nr 1, 131-139 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: Intimate partner violence (IPV) is recognized all over the world for its association with mental health problems in women. In Pakistan, such violence occurs commonly, but detailed information on mental health effects is scarce. The purpose of this study is to focused on married couples in urban Karachi to investigate mental health effects associated with physical, sexual and psychological violence perpetrated by husbands towards wives. Disclosure rates and health care-seeking behaviour were also investigated. METHOD: This cross-sectional study involved 759 women between the ages of 25 and 60 years, selected using a multi-stage random sampling technique. The women were interviewed by trained community midwives using a structured questionnaire. RESULTS: In the total population of women, mental symptoms were prevalent. Women subjected to any form of violence reported, however, considerably poorer mental health than unexposed women. A statistically significant difference for almost all of the studied health parameters persisted even after controlling for socio-demographic factors. The strongest associations were found for suicidal thoughts and physical violence (OR 4.41; 3.18-6.12), sexual abuse (OR 4.39; 3.17-6.07) and psychological abuse (OR 5.17; 3.28-8.15). The interviews revealed that only 27% of the women subjected to violence had disclosed this to anyone, in most cases to their parents. CONCLUSION: The findings in this study highlight that the violence women have to face contributes to the development of multiple forms of psychological stress and serious mental health problems. Women's restrictive life circumstances seriously hamper women's empowerment. Reliable health surveillance system and health care services are needed to serve abused women. Policy initiatives focused on IPV and gender inequality in Pakistan should be initiated.

    Prognostic significance of specific anti-WT1 IgG antibody level in plasma in patients with ovarian carcinoma2014Inngår i: Cancer Medicine, ISSN 2045-7634, E-ISSN 2045-7634, Vol. 3, nr 4, 909-918 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Ovarian carcinoma (OC) has a poor prognosis and lack early effective screening markers. Wilm's tumor gene 1 (WT1) is overexpressed in OCs. Therefore, it is of great interest to investigate whether WT1-specific antibody (Ab) measurements in plasma can serve as a biomarker of anti-OC response, and is of importance in relation to patient prognosis. Peripheral blood samples were obtained from a total of 103 women with ovarian tumors with median being 1 day (range 0-48 days) before operation. WT1 IgG Ab levels were evaluated using enzyme-linked immunosorbent assay (ELISA). Immunohistochemical analysis of WT1 protein expression was performed on OC tissue samples. We found that low-WT1 Ab level in plasma was related to improved survival in patients diagnosed at stages III-IV and grade 3 carcinomas. Positive WT1 protein staining on OC tissue samples had a negative impact on survival in the entire cohort, both overall survival (OS) (P = 0.046) and progression-free survival (PFS) (P = 0.006), but not in the serous OC subtype. Combining WT1 IgG Ab levels and WT1 staining, patients with high-WT1 IgG Ab levels in plasma and positive WT1 protein staining in cancer tissues had shorter survival, with a significant association in PFS (P = 0.016). These results indicated that WT1 Ab measurements in plasma and WT1 staining in tissue specimens could be useful as biomarkers for patient outcome in the high-risk subtypes of OCs for postoperative individualized therapy.

    Acute intermittent porphyria in women: clinical expression, use and experience of exogenous sex hormones. A population-based study in northern Sweden2003Inngår i: Journal of Internal Medicine, ISSN 0954-6820, E-ISSN 1365-2796, Vol. 254, nr 2, 176-183 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    OBJECTIVE: To describe the clinical expression of acute intermittent porphyria (AIP) in women, their use of exogenous sex hormones, and the effects on AIP. DESIGN: A retrospective population-based study. SUBJECTS: All women aged > or =18 years (n = 190) with DNA-diagnosed AIP in northern Sweden. RESULTS: A total of 166 women (87%) participated; 91 (55%) had manifest AIP. Severe attacks were reported by 82%; 39% reported recurrent premenstrual AIP attacks and 22% reported chronic AIP symptoms. Oral hormonal contraceptives had been used by 58% of all these women and by 50 with manifest AIP (57%). Twelve women (24%) associated oral contraceptives as precipitating AIP attacks; in nine cases their first attack. One woman experienced relief from AIP symptoms. On commencing their treatment, 72% of the women with manifest AIP had not yet suffered their first attack. Twenty-two women (25%) aged > or =45 years had used hormonal replacement therapy (HRT) at menopause to remedy climacteric symptoms (the percutaneous route was most frequently used); no AIP attack was precipitated. HRT to remedy vaginal dryness was used by 26 women (28%) aged > or =45 years without triggering an AIP attack. Miscarriages were more frequent in women with manifest AIP (50%) than in the latent group (30%, P = 0.014). CONCLUSIONS: About half of the women with AIP had used oral hormonal contraceptives. As 25% of women with manifest AIP reported attacks associated with such drugs, caution must still be recommended. Menopausal HRT only rarely affected the disorder. Miscarriage was more common amongst women with manifest AIP.

    Implications of psychiatric disorders during pregnancy and the postpartum period - A population-based study2004Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Background: Depressive and anxiety disorders are common health problems, affecting women at least twice as often as men. Although some studies have been made on pregnant women or, especially, in the postpartum period, most of these studies have been performed on small samples, mainly specific risk groups such as teenage mothers, women of low socioeconomic status and certain ethnic groups. Also, there is a lack of studies on antenatal and postpartum depression and/or anxiety using diagnostic criteria adhering to the Diagnostic and Statistical Manual of Mental disorders, fourth edition (DSM-IV).

    Aims and methods: The aims were to estimate the point prevalence of mood, anxiety and eating disorders, based on DSM-IV criteria, in an unselected population during the second trimester of pregnancy, and to assess the obstetric and neonatal outcome, as well as the health care consumption during pregnancy, delivery and the early postpartum period among women with a psychiatric disorder, compared to healthy subjects. Finally, we aimed to investigate depression and anxiety, and associated maternal characteristics and events through pregnancy and the postpartum period in the same group of women. The Primary Care Evaluation of Mental Disorders (PRIME-MD) was used for assessment of psychiatric disorders during the second trimester of pregnancy and three to six months after delivery. From October 2nd, 2000, to October 1st, 2001 all women attending the second trimester routine ultrasound-screening at two different hospitals in northern Sweden (at Umeå University Hospital and at Sunderby Central Hospital) were approached for participation in the study. After delivery, data were extracted from the medical records of the mothers and their offspring to evaluate obstetric and neonatal outcome. Three to six months after delivery, the women who had an antenatal depression and/or anxiety were contacted for an assessment using the PRIME-MD. The same procedure was made in a control group, consisting of 500 women, randomly selected among those who did not have any psychiatric diagnosis according to the PRIME-MD investigation during the second trimester of pregnancy.

    Results and conclusions: Of the 1555 women in the study population, 220 (14.1%) had one or more PRIME-MD diagnoses. Living single, low socioeconomic status, smoking, multiparity and a body mass index of 30 or more were significantly associated with a psychiatric diagnosis in the second trimester of pregnancy. Women with antenatal depression and/or anxiety more often suffered from nausea and vomiting during pregnancy were more often on sick leave, and they visited their obstetrician more often than healthy subjects, specifically because of fear of childbirth and premature contractions. Also, they were more commonly delivered by elective caesarean section, had an increased use of epidural analgesia and reported a longer self-experienced duration of labor. Severe complications of pregnancy, delivery, and the early postpartum period were not affected by antenatal depression and/or anxiety. There was no significant difference in neonatal outcome depending on antenatal depressive or anxiety disorder. Fewer cases of depressive and/or anxiety disorders were prevalent postpartum, but there was a significant shift from a majority of sub-threshold diagnoses during pregnancy to full DSM-IV diagnoses during the postpartum period. Previous psychiatric disorder and living singly were significantly associated with both a new-onset and a postpartum continuation/recurrence of depression and/or anxiety. Postpartum continuation/recurrence of a psychiatric disorder was additionally associated with smoking, obesity, and adverse obstetric events.

    Point prevalence of psychiatric disorders during the second trimester of pregnancy: a population-based study.2003Inngår i: American Journal of Obstetrics and Gynecology, ISSN 0002-9378, E-ISSN 1097-6868, Vol. 189, nr 1, 148-154 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    OBJECTIVE: This study was undertaken to determine the point prevalence of psychiatric disorders during the second trimester of pregnancy in a population-based sample of pregnant women. STUDY DESIGN: Participants were 1795 consecutive pregnant women attending routine ultrasound screening at two obstetric clinics in Northern Sweden during 1 year. The Primary Care Evaluation of Mental Disorders (PRIME-MD) was used for evaluating. RESULTS: Overall, 1734 (96.6%) of the women filled in the PRIME-MD patient questionnaire. Psychiatric disorders were present in 14.1% of the women. Major depression was prevalent in 3.3% of patients and minor depression in 6.9% of patients. Anxiety disorders were encountered in 6.6% of patients. Women with psychiatric disorders displayed significantly more somatic symptoms and more pronounced fear of childbirth. Among diagnosed patients, only 5.5% had some form of treatment. CONCLUSION: The prevalence of mood and anxiety disorders in this unselected population of pregnant women was high and the majority of the women were found to be undiagnosed and untreated.

    Depression and anxiety during pregnancy and six months postpartum: a follow-up study2006Inngår i: Acta Obstetricia et Gynecologica Scandinavica, ISSN 0001-6349, E-ISSN 1600-0412, Vol. 85, nr 8, 937-944 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    AIMS: To investigate the relationship between antenatal and postpartum depression and anxiety and to explore associated maternal characteristics. METHODS: From a population-based sample of 1,555 women attending two obstetric clinics in Sweden, all women with an antenatal psychiatric diagnosis (n = 220) and a random selection of healthy women (n = 500) were contacted for a second assessment three to six months postpartum. The Primary Care Evaluation of Mental Disorders was used for evaluation on both occasions. RESULTS: Fewer cases of depressive and/or anxiety disorders were prevalent postpartum compared with the second trimester screening. Depression and/or anxiety were prevalent in 16.5% of postpartal women versus 29.2% of pregnant women. There was a significant shift from a majority of subthreshold diagnoses during pregnancy to full Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition) diagnoses during the postpartum period. A history of previous psychiatric disorder, living single, and obesity were significantly associated with a new-onset postpartum psychiatric disorder. The absence of a previous psychiatric disorder was significantly associated with a postpartum recovery of depression or anxiety. CONCLUSIONS: Depression and anxiety appear to be less common postpartum than during pregnancy.

    Implications of antenatal depression and anxiety for obstetric outcome2004Inngår i: Obstetrics and Gynecology, ISSN 0029-7844, E-ISSN 1873-233X, Vol. 104, nr 3, 467-476 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    OBJECTIVE: To investigate the obstetric outcome and health care consumption during pregnancy, delivery, and the early postpartum period in an unselected population-based sample of pregnant women diagnosed with antenatal depressive and/or anxiety disorders, compared with healthy subjects. METHODS: Participants were 1,495 women attending 2 obstetric clinics in Northern Sweden. The Primary Care Evaluation of Mental Disorders was used to evaluate depressive and anxiety disorders in the second trimester of pregnancy. To assess demographic characteristics, obstetric outcome, and complications, the medical records of the included women were reviewed. RESULTS: Significant associations were found between depression and/or anxiety and increased nausea and vomiting, prolonged sick leave during pregnancy and increased number of visits to the obstetrician, specifically, visits related to fear of childbirth and those related to contractions. Planned cesarean delivery and epidural analgesia during labor were also significantly more common in women with antenatal depression and/or anxiety. CONCLUSION: There is an association between antenatal depressive and/or anxiety disorders and increased health care use (including cesarean deliveries) during pregnancy and delivery.

    Neonatal outcome following maternal antenatal depression and anxiety: a population-based study.2004Inngår i: American Journal of Epidemiology, ISSN 0002-9262, E-ISSN 1476-6256, Vol. 159, nr 9, 872-881 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The aim of this study was to determine neonatal outcomes among women who had depressive and anxiety disorders during the second trimester of pregnancy in a population-based sample. Participants were 1,465 women and their neonates born at two obstetric clinics in Sweden. The inclusion period for the women was October 2, 2000-October 1, 2001. The Primary Care Evaluation of Mental Disorders (PRIME-MD) classification system was used to evaluate mental disorders in the second trimester of pregnancy. For assessment of demographic characteristics, birth statistics, and birth-related complications, the medical records of the included women and their offspring were reviewed after delivery. The study results revealed no differences in neonatal outcome between women with antenatal depressive disorders and/or anxiety disorders and healthy subjects. The authors conclude that neonatal outcome did not deteriorate despite the women's impaired mental health during pregnancy.

    Swedish maternal mortality in the 19th century by different definitions: previous stillbirths but not multiparity risk factor for maternal death.2000Inngår i: Acta Obstetricia et Gynecologica Scandinavica, ISSN 0001-6349, E-ISSN 1600-0412, Vol. 79, nr 8, 679-86 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In conclusion, this study shows that the mother's reproductive history was the most important risk factor measured for all definitions of maternal death. Grand multiparity did not increase the risk of maternal death. Maternal mortality ratio varied threefold in the study population, depending on the definition used. The high mortality ratios found in this study, only declining by the end of the century, should be interpreted as a general condition of the society since no significant differences could be perceived regarding social class, while unmarried women were more at risk.

    The impact of neonatal mortality on subsequent survival in rural Ethiopia.2002Inngår i: Annals of Tropical Paediatrics, ISSN 0272-4936, Vol. 22, nr 1, 25-32 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    In countries where most deliveries occur at home and most available information is hospital-based, accurate information on neonatal mortality is difficult to obtain. This study was conducted in a rural community in Ethiopia that has been under monthly demographic surveillance since 1987. The analysis in this paper was based on data collected in the 1st decade (1987-96) and this database was used to calculate mortality incidence rates and analyse survival. The overall neonatal mortality rate was 27/1000 live births (95% CI 24.5-29.5). The rates in the early and late neonatal periods were 20 and 8/1000 live births, respectively (95% CIs 18.0-22.9 and 6.6-9.4). The mortality incidence rates show that, every day, three of every 1000 newborns die in their 1st week of life. Neonatal mortality accounted for 43% of infant mortality. If all neonates survived the 1st week of life, life expectancy would increase by 1 year. Increased risk of neonatal mortality was found to be associated with living in a rural lowland area, twin births and male gender. This paper also addresses the need for further identification of the complex environmental and behavioural risk factors for neonatal mortality and for instituting appropriate and affordable interventions to reduce neonatal mortality.

    Screening and cervical cancer cure: population based cohort study2012Inngår i: BMJ. British Medical Journal, ISSN 0959-535X, E-ISSN 1756-1833, Vol. 344, e900- s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objective To determine whether detection of invasive cervical cancer by screening results in better prognosis or merely increases the lead time until death.

    Design Nationwide population based cohort study. Setting Sweden.

    Participants All 1230 women with cervical cancer diagnosed during 1999-2001 in Sweden prospectively followed up for an average of 8.5 years. Main outcome measures Cure proportions and five year relative survival ratios, stratified by screening history, mode of detection, age, histopathological type, and FIGO (International Federation of Gynecology and Obstetrics) stage.

    Results In the screening ages, the cure proportion for women with screen detected invasive cancer was 92% (95% confidence interval 75% to 98%) and for symptomatic women was 66% (62% to 70%), a statistically significant difference in cure of 26% (16% to 36%). Among symptomatic women, the cure proportion was significantly higher for those who had been screened according to recommendations (interval cancers) than among those overdue for screening: difference in cure 14% (95% confidence interval 6% to 23%). Cure proportions were similar for all histopathological types except small cell carcinomas and were closely related to FIGO stage. A significantly higher cure proportion for screen detected cancers remained after adjustment for stage at diagnosis (difference 15%, 7% to 22%).

    Conclusions Screening is associated with improved cure of cervical cancer. Confounding cannot be ruled out, but the effect was not attributable to lead time bias and was larger than what is reflected by down-staging. Evaluations of screening programmes should consider the assessment of cure proportions.

    Screening-preventable cervical cancer risks: evidence from a nationwide audit in Sweden2008Inngår i: Journal of the National Cancer Institute, ISSN 0027-8874, E-ISSN 1460-2105, Vol. 100, nr 9, 622-629 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: The effectiveness of cervical cancer screening programs differs widely in different populations. The reasons for these differences are unclear. Routine and comprehensive audits have been proposed as an ethically required component of screening. We performed a nationwide audit of the effectiveness of the Swedish cervical cancer screening program.

    METHODS: We identified all invasive cervical cancer cases that were diagnosed in Sweden from January 1, 1999, through December 31, 2001, and had been reported to the Swedish Cancer Registry (n = 1230 cases). We verified the diagnoses by histopathologic rereview and matched each case subject to five (population-based) age-matched control subjects who were identified from the National Population Register. The Pap smear screening histories for case and control subjects were reviewed for a 6-year period using the National Cervical Cancer Screening Register, which contains data on essentially all relevant cytological and histological diagnoses in Sweden. Odds ratios (ORs), and their 95% confidence intervals (CIs), of cervical cancer according to screening history were calculated in conditional logistic regression models. All statistical tests were two-sided.

    RESULTS: Women who had not had a Pap smear within the recommended screening interval had higher risk of cervical cancer than women who had been screened (OR = 2.52, 95% CI = 2.19 to 2.91). This risk was similarly increased for all age groups (P(homogeneity) = .96). The risk for non-squamous cell cervical cancers (OR = 1.59, 95% CI = 1.20 to 2.11) was also increased. Women who had not had a Pap smear within the recommended screening interval had a particularly high risk of advanced cancers (OR = 4.82, 95% CI = 3.61 to 6.44). Among women who had been screened within the recommended interval, those with abnormal Pap smears had a higher risk of cervical cancer than those with normal smears (OR = 7.55, 95% CI = 5.88 to 9.69) and constituted 11.5% of all women with cervical cancer.

    CONCLUSIONS: Nonadherence to screening intervals was the major reason for cervical cancer morbidity. The screening program was equally effective for women of all ages and was also effective against non-squamous cancers.

    Allopregnanolone and mood: studies of postmenopausal women during treatment with progesterone2006Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Introduction. Allopregnanolone and pregnanolone (neuroactive metabolites of progesterone) act as positive modulators of the GABAA receptor system which is the major inhibitory system in CNS. Contradictory results on the effect of GABAA receptor modulators are reported. Beneficial properties such as anaesthesia, sedation, and anxiolysis are reported as well as adverse, anxiogenic and aggressive effects. It has been suggested that GABAA receptor agonists have bimodal effects. Low concentrations increase an adverse, anxiogenic effect, whereas higher concentrations show beneficial, calming properties.

    Aims. To investigate if progesterone treatment induces adverse mood in postmenopausal women and if the severity in mood symptoms is related to progesterone, allopregnanolone or pregnanolone serum concentrations. To evaluate differences in steroid concentrations induced by different doses and routes of administration of progesterone.

    Methods. Two randomised, placebo-controlled, double-blind crossover studies of postmenopausal women were performed. Subjects were treated with estradiol continuously. Different doses of progesterone, given vaginally or orally, were added sequentially during the last 14 days of each treatment cycle. Daily symptom ratings were kept using a validated rating scale. Blood samples for progesterone, allopregnanolone and pregnanolone analyses were collected during each treatment cycle. A study regarding the pharmacokinetics after ingestion of low-dose oral progesterone was conducted with postmenopausal women. Blood samples for the analyses of progesterone, allopregnanolone and pregnanolone were collected and pharmacokinetic parameters were calculated.

    Results. Certain postmenopausal women on sequential HT with vaginal and oral progesterone experience mood deterioration during the progesterone phase while on a low dose of progesterone but not on higher doses or the placebo. Negative mood symptoms occurred when the serum concentration of allopregnanolone was similar to endogenous luteal phase levels, whereas lower and higher concentrations had no effect on mood. Pharmacokinetic analyses show that low-dose oral progesterone can be used as a prodrug to allopregnanolone when the aim is to achieve physiological concentrations of allopregnanolone.

    Conclusions. A bimodal association between allopregnanolone concentration and adverse mood is observed in postmenopausal women treated with progesterone. The addition of low-dose progesterone to estradiol induces adverse mood in postmenopausal women, whereas higher doses and placebo have no mood-deteriorating effect.

    Sex steroid induced negative mood may be explained by the paradoxical effect mediated by GABAA modulators2009Inngår i: Psychoneuroendocrinology, ISSN 0306-4530, E-ISSN 1873-3360, Vol. 34, nr 8, 1121-1132 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Certain women experience negative mood symptoms as a result of progesterone during the luteal phase of the menstrual cycle, progestagens in hormonal contraceptives, or the addition of progesterone or progestagens in sequential hormone therapy (HT). This phenomenon is believed to be mediated via the action of the progesterone metabolites on the GABA(A) system, which is the major inhibitory system in the mammalian CNS. The positive modulators of the GABA(A) receptor include allopregnanolone and pregnanolone, both neuroactive metabolites of progesterone, as well as benzodiazepines, barbiturates, and alcohol. Studies on the effect of GABA(A) receptor modulators have shown contradictory results; although human and animal studies have revealed beneficial properties such as anaesthesia, sedation, anticonvulsant effects, and anxiolytic effects, recent reports have also indicated adverse effects such as anxiety, irritability, and aggression. It has actually been suggested that several GABA(A) receptor modulators, including allopregnanolone, have biphasic effects, in that low concentrations increase an adverse, anxiogenic effect whereas higher concentrations decrease this effect and show beneficial, calming properties. The allopregnanolone increase during the luteal phase in fertile women, as well as during the addition of progesterone in HT, has been shown to induce adverse mood in women. The severity of these mood symptoms is related to the allopregnanolone serum concentrations in a manner similar to an inverted U-shaped curve. Negative mood symptoms occur when the serum concentration of allopregnanolone is similar to endogenous luteal phase levels, while low and high concentrations have less effect on mood. It has also been shown that progesterone/allopregnanolone treatment in women increases the activity in the amygdala (as measured with functional magnetic resonance imaging) in a similar way to the changes seen during anxiety reactions. However, it is evident that only certain women experience adverse mood during progesterone or GABA(A) receptor modulator treatments. Women with premenstrual dysphoric disorder (PMDD) have severe luteal phase related symptoms; in this phase, they show changes in GABA(A) receptor sensitivity and GABA concentrations that are related to the severity of the condition. These findings suggest that negative mood symptoms in women with PMDD are caused by the paradoxical effect of allopregnanolone mediated via the GABA(A) receptor. CONCLUSION: Progesterone and progestagens induce negative mood, most probably via their GABA(A) receptor active metabolites. In postmenopausal women treated with progesterone and animals treated with allopregnanolone, there is a bimodal association between serum allopregnanolone concentration and adverse mood, resembling an inverted U-shaped curve. In humans, the maximal effective concentration of allopregnanolone for producing negative mood is within the range of physiological luteal phase serum concentrations.

    Determination of C-21 ketosteroids in serum using trifluoromethanesulfonic acid catalyzed precolumn dansylation and 1,1’-oxalyldiimidazole postcolumn peroxyoxalate chemiluminescence detection1998Inngår i: Analytical Chemistry, ISSN 0003-2700, E-ISSN 1520-6882, Vol. 70, nr 23, 5002-5009 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    A new procedure for the quantitation of C-21 ketosteroids using trifluoromethanesulfonic acid-catalyzed precolumn dansylation and coupled column liquid chromatographic separation, followed by postcolumn 1,1‘-oxalyldiimidazole peroxyoxalate chemiluminescence detection is presented. In the simultaneous optimization of chromatographic resolution and chemiluminescence intensity, a coupled column chromatographic system and a stopped-flow system were used. An eluent containing 20 mM phosphate buffer at pH 6.7 accomplished an efficient separation of 3α-hydroxy-5β-pregnan-20-one from a mixture containing 10 C-21 ketosteroids. Phosphate buffer also proved to be the most advantageous, among the six buffers tested, for sensitive detection. Experimental design and multivariate data analysis were used to characterize and optimize the postcolumn reaction chemistry in the chromatographic system. A valid full factorial design with excellent predictability showed that the flow rates for both 1,1‘-oxalyldiimidazole and hydrogen peroxide were the factors most strongly affecting the sensitivity of the system. The theoretical plate numbers were above 11 000 for all 10 dansylated ketosteroids. The 3σ detection limit estimated from 3α-hydroxy-5β-pregnan-20-one calibration curve data was 1.6 pmol (n = 4, 125 μL injected) and spiked serum containing 0−74 pmol of this compound showed overall recoveries of 73 ± 9% (n = 12). Quantitation of 3α-hydroxy-5β-pregnan-20-one was finally carried out on 45 serum samples and the results compared to those from a radioimmunoassay (RIA) method. The data acquired with the procedure described in this work compare well with the results from RIA, which confirms the reliability of the new analytical procedure.

    Robot-assisted surgery in cervical cancer patients reduces the time to normal activities of daily living2015Inngår i: Acta Obstetricia et Gynecologica Scandinavica, ISSN 0001-6349, E-ISSN 1600-0412, Vol. 94, nr 3, 260-265 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    ObjectiveTo evaluate current surgical cervical cancer treatment in Sweden 2008-12. Design and settingAnalysis of data in the Swedish National Quality Register for Gynecological Surgery (GynOP). SampleA total of 249 cervical cancer patients undergoing surgery. MethodsAnalysis of prospectively gathered preoperative and postoperative data including patient-reported information. Main outcome measuresMean operating time, blood loss/transfusion, length of hospital stay, return to activities of daily living. ResultsThe patients undergoing laparoscopic robot-assisted surgery (n=64) or laparotomy (n=185) did not differ in age, body mass index, American Society of Anesthesiologists score, International Federation of Gynecology and Obstetrics (FIGO) stage or mean operating time. Blood loss was higher in the laparotomy group (p<0.001). Thirteen patients in the laparotomy group (7%) received a blood transfusion, but none in the robot group. Intraoperative complications were more common in the laparotomy group (p=0.03). Re-admission or operations did not differ between the groups. The number of pelvic lymph nodes removed was significantly higher in the laparotomy group (median 31 vs. 24, p<0.001). There was no difference regarding the number of patients with lymph node metastases in the two groups. The postoperative length of hospital stay was longer in the laparotomy group compared with the robot group (6.1days vs. 2.1days, p=0.01). The patient-reported time to resume normal activities of daily living was longer in the laparotomy than the robot group (13.4days vs. 9.7days, p=0.04). ConclusionsLaparoscopic robotic-assisted surgery is preferable to laparotomy for cervical cancer patients because it entails a significantly shorter hospital stay, less blood loss, fewer intraoperative complications and shorter time to normal daily activities.

    Prefrontal activity during response inhibition decreases over time in the postpartum period2013Inngår i: Behavioural Brain Research, ISSN 0166-4328, E-ISSN 1872-7549, Vol. 241, 132-138 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The postpartum period is characterized by complex hormonal changes, but human imaging studies in the postpartum period have thus far predominantly focused on the neural correlates of maternal behavior or postpartum depression, whereas longitudinal studies on neural correlates of cognitive function across the postpartum period in healthy women are lacking. The aim of this study was to longitudinally examine response inhibition, as a measure of executive function, during the postpartum period and its neural correlates in healthy postpartum women and non-postpartum controls. Thirteen healthy postpartum women underwent event-related functional magnetic resonance imaging while performing a Go/NoGo task. The first assessment was made within 48 h of delivery, and the second at 4-7 weeks postpartum. In addition, 13 healthy women examined twice during the menstrual cycle were included as non-postpartum controls. In postpartum women region of interest analyses revealed task-related decreased activations in the right inferior frontal gyrus, right anterior cingulate, and bilateral precentral gyri at the late postpartum assessment. Generally, postpartum women displayed lower activity during response inhibition in the bilateral inferior frontal gyri and precentral gyri compared to non-postpartum controls. No differences in performance on the Go/NoGo task were found between time-points or between groups. In conclusion, this study has discovered that brain activity in prefrontal areas during a response inhibition task decreases throughout the course of the first postpartum weeks and is lower than in non-postpartum controls. Further studies on the normal adaptive brain activity changes that occur during the postpartum period are warranted. (C) 2012 Elsevier B.V. All rights reserved.

    Stress steroids as accelerators of Alzheimer's disease.: Effects of chronically elevated levels of allopregnanolone in transgenic AD models.2013Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Background Alzheimer’s disease (AD) and dementia are devastating con­ditions not only for the affected patients but also for their families.  The economical costs for the society are tremendous. Mid-life psychological stress, psychosocial stress and post-traumatic stress disorder cause cognitive dysfunction and lead to increased risk for dementia. However, the mecha­nisms behind stress-induced AD and dementia are not known. AD is char­acterized by solid amyloid plaques in the CNS. However, over the last decade it has been concluded that the levels of soluble beta-amyloid (Aβ) correlate to cognitive performance while plaques often do not. The soluble Aβ accu­mulate intracellularly and disturb the synaptic function. Interestingly, the levels of intracellular Aβ depend on neuronal activity. Previous studies have shown that decreased neuronal activity cause increased intracellular levels of Aβ and cognitive decline. Stress steroids produced in the brain, e.g. allopreg­nanolone, enhance the activity of the GABAergic system, i.e. the main in­hibitory system of the brain. Consequently, allopregnanolone affects neu­ronal activity. Therefore, it is possible that elevated levels of allopreg­nanolone (due to e.g. stress) cause increased intracellular levels of Aβ. This could be a mechanism behind stress-induced AD. The purpose of this thesis was to investigate if elevation of allopregnanolone is a possible link in the mechanism behind stress-induced AD by investigating the effects of chroni­cally elevated levels of allopregnanolone in transgenic mouse models for AD.

    Methods Swe/PS1 and Swe/Arc mice (transgenic models for AD) were treated chronically with elevated allopregnanolone levels, comparable to those at mild stress. After an interval of no treatment, the mice were tested for learning and memory performance in the Morris water maze. The brain tissue of the mice was then analyzed for disease markers, i.e. soluble and insoluble Aβ40 and Aβ42 using enzyme-linked immunosorbent assay, and amyloid plaques using immunohistochemistry and Congo red staining tech­nique. The brain tissue was also analyzed for a marker of synaptic function, i.e. synaptophysin.

    Results Chronic treatment of allopregnanolone caused impaired learning performance in both the Swe/PS1 and the Swe/Arc mouse models. The Swe/PS1 mice had increased levels of soluble Aβ in both hippocampus and cortex. Interestingly, the levels of soluble Aβ were unchanged in the Swe/Arc mice. Three months of allopregnanolone treatment in the Swe/PS1 mouse model caused decreased plaque size, predominantly in hippocampus. It may be concluded that chronic allopregnanolone elevation caused smaller but more abundant congophilic plaques as both total plaque area and number of plaques were increased in mice with poor learning ability. Additional spots for accumulation of Aβ, predominantly the more toxic Aβ42, and thus addi­tional starting points for plaque production could be a part of the mechanism behind stress-induced Alzheimer’s disease.

    Conclusions The conclusion of this thesis is that chronic elevation of allo­pregnanolon accelerated the development of Alzheimer’s disease in the Swe/PS1 and the Swe/Arc transgenic mouse models. Allopregnanolone may be an important link in the mechanism behind stress-induced AD. However, further studies are required to grasp the extent of its pathological influence.

    Brief but Chronic Increase in Allopregnanolone Cause Accelerated ADPathology Differently in Two Mouse Models2013Inngår i: Current Alzheimer Research, ISSN 1567-2050, Vol. 10, nr 1, 38-47 s.Artikkel i tidsskrift (Fagfellevurdert)

    Abstract: Previously, we have shown that chronic treatment with allopregnanolone (ALLO) for three months impaired learning function in the Swe/PS1 mouse model. ALLO is a neurosteroid, produced in the CNS and a GABAA receptor agonist. ALLO modulates the general inhibitory system in the CNS by enhancing the effect of GABA. Chronic treatment with other GABAA receptor active compounds, such as benzodiazepines, ethanol and medroxy-progesterone acetate has been associated to cognitive decline and/or increased risk for dementia. In this study, we sufficed with a treatment period of one month for the Swe/PS1 mouse, and included another Alzheimer’s disease mouse model; the Swe/Arc model. We found that one month of chronic treatment with elevated ALLO levels within physiological range impaired learning and memory function in the Swe/Arc female and male mice. Male Swe/PS1 mice also showed marginally impaired function, while the female mice did not. Furthermore, the chronic ALLO treatment caused increased levels of soluble Aβ in the Swe/PS1 mouse model while the levels were unchanged in the Swe/Arc model. Therefore, both Swe/Arc and Swe/PS1 mice showed signs of accelerated disease progression. Still, further studies are required to determine the mechanisms behind the cognitive impairment and the increased Aβ-levels caused by mildly elevated ALLO-levels. learning function in the Swe/PS1 mouse model.

    Chronic Allopregnanolone Treatment Accelerates Alzheimer's Disease Development in A beta PP(Swe)PSEN1(Delta E9) Mice2012Inngår i: Journal of Alzheimer's Disease, ISSN 1387-2877, Vol. 31, nr 1, 71-84 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The endogenous neurosteroid allopregnanolone alters neuronal excitability via modulation of the GABA(A) receptor and causes decreased neurotransmission. In Alzheimer's disease (AD), neurotransmission seems to alter the levels of toxic intracellular amyloid-beta (A beta) oligomers, which are implicated in AD pathogenesis and cause cognitive decline. Inhibition of synaptic activity has been shown to increase levels of intracellular A beta. Allopregnanolone at endogenous stress levels inhibits synaptic activity and could have similar effects. By using a transgenic A beta PP(Swe)PSEN1(Delta E9) mouse model for AD, we observed that chronic allopregnanolone treatment for three months with stress levels of allopregnanolone impaired learning in the Morris water maze. The learning impairment was seen one month after the end of treatment. Chronic allopregnanolone treatment also led to increased levels of soluble A beta in the brain, which could be a sign of advanced pathogenesis. Since the learning and memory of wild-type mice was not affected by the treatment, we propose that chronic allopregnanolone treatment accelerates the pathogenesis of AD. However, further studies are required in order to determine the underlying mechanism.

    Long-term continuous allopregnanolone elevation causes memory decline and hippocampus shrinkage, in female wild-type B6 mice2016Inngår i: Hormones and Behavior, ISSN 0018-506X, E-ISSN 1095-6867, Vol. 78, 160-167 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Chronic stress in various forms increases the risk for cognitive dysfunction, dementia and Alzheimer's disease. While the pathogenesis behind these findings is unknown, growing evidence suggests that chronic increase in neurosteroid levels, such as allopregnanolone, is part of the mechanism. We treated wild-type C57BL/6J mice with allopregnanolone for 5months, using osmotic pumps. This treatment led to moderately increased levels of allopregnanolone, equivalent to that of mild chronic stress. After an interval of no treatment for 1month, female mice showed impaired learning and memory function in the Morris water maze (MWM) in combination with diminished hippocampus weight and increased cerebellum weight, both correlating to MWM performance. Male mice showed a minor reduction in memory function and no differences in brain structure. We conclude that chronic allopregnanolone elevation can lead to cognitive dysfunction and negative brain alterations. We suggest that allopregnanolone could play a key role in the pathogenesis of stress-induced cognitive disturbances and perhaps dementia.

    Isoallopregnanolone antagonize allopregnanolone-induced effects on saccadic eye velocity and self-reported sedation in humans2015Inngår i: Psychoneuroendocrinology, ISSN 0306-4530, E-ISSN 1873-3360, Vol. 52, 22-31 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Allopregnanolone (AP) is an endogenous neurosteroid. It modulates the effect of gamma-amino-butyric acid (GABA) on the GABA type A (GABA(A)) receptor, which leads to increased receptor activity. Since the GABA-system is mainly inhibitory, increased AP activity leads to modulation of neuronal activity. In vitro studies of GABA(A) receptor activity and in vivo animal studies of sedation have shown that AP-induced effects can be inhibited by another endogenous steroid, namely isoallopregnanolone (ISO). In this study we investigated if ISO can antagonize AP-induced effects in healthy female volunteers, via measurements of saccadic eye velocity (SEV) and self-rated sedation. With a single-blind cross-over design, 12 women were studied on three separate occasions; given AP alone or AP in combination with one of two ISO doses. Congruent with previous reports, AP administration decreased SEV and induced sedation and these effects were diminished by simultaneous ISO administration. Also, the ISO effect modulation was seemingly stronger for SEV than for sedation. These effects were observed already at an ISO dose exposure that was approximately half of that of AP. In conclusion, ISO antagonized AP-induced decrease in SEV and self-reported sedation, probably in a non-competitive manner.

    Chronic allopregnanolone elevation cause altered plaque production in Swe/PS1 miceManuskript (preprint) (Annet vitenskapelig)
    Abstract [en]

    Abstract. We have previously shown that chronic elevation of the neurosteroid allopregnanolone caused learning dysfunction and increased levels of soluble Aβ in the Swe/PS1 mouse model. The mechanism behind these findings is however unknown. We further investigated the brain tissue of these mice to identify any effects on congophilic plaque burden, Aβ42-specific plaque burden and synaptic function. We found a significant reduction in the average size of the congophilic core of neuritic plaques after chronic allopregnanolone treatment compared to vehicle. This seems to be caused by an altered plaque production, leading to more abundant, but smaller neuritic plaques. We may also have detected a decrease in the amount of synaptophysin, and thus synaptic function among the same mice. However, the long interval between the end of treatment and tissue collection possibly allowed time for recovery and only minor differences were noted. We found that the natural relationship between levels of insoluble Aβ, congophilic and Aβ42-specific plaque load was disrupted after chronically elevated allopregnanolone levels. Furthermore, the levels of syn-aptophysin and insoluble Aβ became more important in the relationship to learning and memory. The causality of these factors is still unknown and further studies are required to fully understand the effect of neurosteroids on AD development.

    Predictive factors of the outcome of primary surgical treatment of stress incontinence in women1997Inngår i: Scandinavian Journal of Urology and Nephrology, ISSN 0036-5599, E-ISSN 1651-2065, Vol. 31, nr 1, 49-55 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Forty-five women with stress incontinence (mean age 50 years) scheduled for surgical treatment randomized either to retropubic urethrocystopexy or to pubococcygeal repair were prospectively studied. Fifty healthy women were used as a reference group. No difference emerged concerning the outcome for these two surgical techniques in terms of success rate. Consequently, the subjects were treated as one group. The aim of the study was to test for predictive factors of the outcome of surgical treatment. Age of the patient, duration of stress incontinence, parity, personality, psychological and social factors were investigated. The outcome of surgical treatment was estimated both subjectively and objectively (pad test). The women were classified as cured or improved/failure. There was an 80% concordance between subjective and objective methods. In the stress incontinent women who were improved/failure one year after surgery, a high degree of neuroticism, low degree of extraversion, high degree of somatic anxiety, psychic anxiety, psychasthenia and suspicion was observed compared to the cured women. Furthermore, the improved/failure women had a lower level of social integration, in terms of loneliness compared to the cured women. Our findings point to the need of psychosocial support and care in addition to the medical treatment. According to a stepwise logistic regression analysis three variables have been found of importance as predictors of the outcome of the surgical treatment: duration of stress incontinence, neuroticism and age of patient.

    Social adjustment and spouse relationships among women with stress incontinence before and after surgical treatment1996Inngår i: Social Science and Medicine, ISSN 0277-9536, E-ISSN 1873-5347, Vol. 42, nr 11, 1537-1544 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Forty-five women with stress urinary incontinence (SUI) and their partners have been interviewed three months before and one year after surgical treatment to investigate the social consequences of their impairment. One year after surgery 76% of the women reported that they were cured (group A, n = 34) and 24% that they were improved (group B, n = 11). The cured women were significantly younger than the improved women. The duration of urinary leakage before the operation was significantly shorter in group A than in group B. One year post surgery group A reported a significantly decrease in impediments to exert certain tasks due to urine leakage. As concerns leisure time, group A reported a higher level of overall activities before surgery than group B, whereas postsurgery both groups obtained about the same level of activities. Regarding social support, no differences between the groups occurred as concerns attachment. Furthermore, group A women showed a significantly higher degree of adequacy of social integration compared with group B. The majority of the couples could openly discuss sexual matters with their partners and were satisfied with their sexual life. More than half of the interviewed men reported an increase in sexual desire one year after their partners operation. Whereas about every third woman in both groups reported an increase in sexual desire. However, the frequency of intercourse did not change in any groups. In conclusion, this study underlines the importance of social factors in the assessment of the consequences of stress urinary incontinence and its treatment.

    A holistic view of urinary stress incontinence in women1995Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    The present study group consists of 45 women with genuine stress incontinence who were selected for surgical treatment and randomized either to retropubic urethrocystopexy (n=30) or pubococcygeal repair (n=15). The preoperative assessment included medical history, gynecological examination, urine analysis and culture, residual urine, pad test, frequency-continence charts, water urethrocystoscopy, continence test and cystometry with analysis of micturition. Moreover, five semistructured interviews were performed with the women and two with their partner. The following questionnaires were used measuring a) personality characteristics: Karolinska Scales of Personality (KSP), Eysenck Personality Inventory (EPI), b) depression: Beck Depression Inventory (BDI) and c) social support: Interview Schedule for Social Interaction (ISSI).

    The results have shown that there was no difference in the subjective cure rate between the two surgical methods (73% vs. 80 % respectively). The bladder volume had increased in both groups and the intravesical pressure of the bladder filled to maximum had increased in the pubococcygeal repair group. Other urodynamic variables were unchanged by the operation. Pad tests have demonstrated that 67 % of the women in the urethrocystopexy group and 47 % in the pubococcygeal repair group ceased to leak urine. Postoperatively, 63 % of the women in the urethrocystopexy group needed high doses of analgesics compared with only 33 % in the pubococcygeal repair group. Among the women experiencing severe to very severe pain dysphoric subjects were overrepresented. Postoperative residual urine was a minor nursing problem in both groups.

    Women with SUI of long duration scored significantly higher than controls on the KSP scales of somatic anxiety, psychic anxiety, psychasthenia, suspicion and on the EPI lie-scale. There was no significant difference in sexual activity before and after surgery. One or two sexual dysfunctions within the desire, excitement, orgasmic and resolution phase were reported by the majority of women both before and after surgical intervention.

    The cured women reported a higher level of overall activities before surgery than the improved (i.e. not cured) women, whereas post surgery both the cured and the improved women obtained about the same level of activities. Regarding social support, no differences between the cured or improved women occured as concerns attachment. The cured women showed a higher degree of adequacy of social integration compared with the improved women.

    In order to delineate predictive factors for the surgical outcome the following variables were investigated: age of patient, duration of urine leakage, parity, personality, psychological and social factors. The following predictors of the outcome of surgical treatment emerged: duration of stress incontinence, neuroticism and age of patient.

    The results of the present study indicate the ecessity of a multidisciplinary approach to the treatment and nursing of women with SUI.

    Personality traits were assessed by means of the Karolinska Scale of Personality (KSP) and the Eysenck Personality Inventory (EPI) in 45 genuine stress incontinent women and compared with a reference group of continent women in order to investigate the possible impact of this chronic condition on the personality. Women with stress incontinence of long duration scored significantly higher than controls on the KSP scales somatic anxiety, psychic anxiety, psychasthenia and suspicion and on the EPI lie-scale. These findings point to the importance of personality factors in chronic conditions such as urinary incontinence.

    Some Sexological Characteristics of Stress Incontinent Women1996Inngår i: Scandinavian Journal of Urology and Nephrology, ISSN 0036-5599, E-ISSN 1651-2065, Vol. 30, nr 3, 207-212 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Forty-four women with stress urinary incontinence (SUI) were interviewed in order to investigate sexual activities, sexual function and satisfaction one month before and one year after either one of two possible surgical interventions. The findings were related to sexual response cycle, size of urinary leakage, duration of incontinence and depression. There was no significant difference in sexual activity before and after surgery. One or two sexual dysfunctions within the desire, excitement, orgasmic and resolution phases were reported by the majority both before and after intervention independently of surgical method. Neither the magnitude of the leakage nor the duration of SUI influenced the sexual experiences significantly while continence after surgery promoted sexual desire. The discrepances between the prevalence of sexual dysfunctions and the relatively high level of sexual satisfaction as well as the non-influencing parameters indicate the complexity of human sexuality.

    The pre- and postsurgical nursing of women with stress incontinence1996Inngår i: Journal of Advanced Nursing, ISSN 0309-2402, E-ISSN 1365-2648, Vol. 23, nr 3, 502-511 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The aim of the present study was to evaluate subjective and objective methods used for the investigation of stress urinary incontinence (SUI) and to compare the outcome of two different surgical techniques regarding cure rate, postoperative nursing, bladder drainage and postoperative pain relief. The study included 45 women with SUI, randomized either to retropubic urethrocystopexy (n = 30) or pubococcygeal repair (n = 15). The assessment included medical history, gynaecological examination, urine analysis and culture, residual urine, pad test, frequency-continence charts, water urethrocystoscopy, continence test, and cystometry with micturition analysis. Moreover, Beck's Depression Inventory and the Eysenck Personality Inventory were used before surgery. One year after surgery no significant difference in subjective cure rate was found between the two surgical methods (73% vs. 80%, respectively). According to pad tests, 67% of the women in the urethrocystopexy group and 47% in the pubococcygeal repair group had ceased to leak urine. The bladder volume increased significantly in both groups. Sixty-three per cent of the women in the urethrocystopexy and 33% in the pubococcygeal repair group experienced severe to very severe postoperative pain. In these groups, significantly more dysphoric women were found as compared with the group of women with less postoperative pain. Furthermore, the women with more severe pain scored higher on the neuroticism scale. These findings indicate the importance of personality factors in the treatment and nursing of women with SUI.

    Pregnancy-related low back pain and pelvic girdle pain approximately 14 months after pregnancy - pain status, self-rated health and family situation2014Inngår i: BMC Pregnancy and Childbirth, ISSN 1471-2393, Vol. 14, 48- s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Pelvic girdle pain (PGP) in pregnancy is distinct from pregnancy-related low back pain (PLBP). However, women with combined PLBP and PGP report more serious consequences in terms of health and function. PGP has been estimated to affect about half of pregnant women, where 25% experience serious pain and 8% experience severe disability. To date there are relatively few studies regarding persistent PLBP/PGP postpartum of more than 3 months, thus the main objective was to identify the prevalence of persistent PLBP and PGP as well as the differences over time in regard to pain status, self-rated health (SRH) and family situation at 12 months postpartum. Methods: The study is a 12 month follow-up of a cohort of pregnant women developing PLBP and PGP during pregnancy, and who experienced persistent pain at 6 month follow-up after pregnancy. Women reporting PLBP/PGP (n = 639) during pregnancy were followed up with a second questionnaire at approximately six month after delivery. Women reporting recurrent or persistent LBP/PGP at the second questionnaire (n = 200) were sent a third questionnaire at 12 month postpartum. Results: A total of 176 women responded to the questionnaire. Thirty-four women (19.3%) reported remission of LBP/PGP, whereas 65.3% (n = 115) and 15.3% (n = 27), reported recurrent LBP/PGP or continuous LBP/PGP, respectively. The time between base line and the 12 months follow-up was in actuality 14 months. Women with previous LBP before pregnancy had an increased odds ratio (OR) of reporting 'recurrent pain' (OR = 2.47) or 'continuous pain' (OR = 3.35) postpartum compared to women who reported 'no pain' at the follow-up. Women with 'continuous pain' reported statistically significant higher level of pain at all measure points (0, 6 and 12 months postpartum). Non-responders were found to report a statistically significant less positive scoring regarding relationship satisfaction compared to responders. Conclusions: The results from this study demonstrate that persistent PLBP/PGP is a major individual and public health issue among women 14 months postpartum, negatively affecting their self-reported health. However, the perceived relationship satisfaction seems to be stable between the groups.

    Sick leave and healthcare utilisation in women reporting pregnancy related low back pain and/or pelvic girdle pain at 14 months postpartum2016Inngår i: Chiropractic and Manual Therapies, ISSN 2045-709X, E-ISSN 2045-709X, Vol. 24, 7Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Pregnancy related low back pain (PLBP) and pelvic girdle pain (PGP) are considered common complications of pregnancy. The long-term consequences for women with persistent PLBP/PGP postpartum are under-investigated. The main objective was to investigate the prevalence, pattern and degree of sick leave as well as healthcare utilisation and its perceived effect in women with persistent PLBP/PGP at 12 months postpartum.

    Method: This is a follow-up study of a cohort involving of a sample of women, who delivered from January 1st 2002 to April 30th in 2002 at Umea University Hospital and Sunderby Hospital, and who reported PLBP/PGP during pregnancy. A total of 639 women were followed-up by a second questionnaire (Q2) at approximately 6 months postpartum. Women with persistent PLBP/PGP at the second questionnaire (N = 200) were sent a third questionnaire (Q3) at approximately 12 months postpartum.

    Results: The final study sample consisted of 176 women reporting PLBP/PGP postpartum where N = 34 (19.3 %) reported 'no' pain, N = 115 (65.3 %) 'recurrent' pain, and N = 27 (15.3 %) 'continuous' pain. The vast majority (92.4 %) of women reported that they had neither been on sick leave nor sought any healthcare services (64.1 %) during the past 6 months at Q3. Women with 'continuous' pain at Q3 reported a higher extent of sick leave and healthcare seeking behaviour compared to women with 'recurrent' pain at Q3. Most women with persistent PLBP/PGP had been on sick leave on a full-time basis. The most commonly sought healthcare was physiotherapy, followed by consultation with a medical doctor, acupuncture and chiropractic.

    Conclusion: Most women did not report any sick leave or sought any healthcare due to PLBP/PGP the past 6 months at Q3. However, women with 'continuous' PLBP/PGP 14 months postpartum did report a higher prevalence and degree of sick leave and sought healthcare to a higher extent compared to women with 'recurrent' PLBP/PGP at Q3. Women with more pronounced symptoms might constitute a specific subgroup of patients with a less favourable long-term outcome, thus PLBP/PGP needs to be addressed early in pregnancy to reduce both individual suffering and the risk of transition into chronicity.

    Prevalence and predictors of persistent pelvic girdle pain 12 years postpartum2017Inngår i: BMC Musculoskeletal Disorders, ISSN 1471-2474, E-ISSN 1471-2474, Vol. 18, 399Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Pelvic girdle pain (PGP) is not always a self-limiting condition. Women with more pronounced persistent PGP (PPGP) report poorer health status compared to women with less pronounced symptoms. The knowledge concerning the long-term consequences of PPGP is limited, thus more knowledge in this area is needed. The overall aim was to study the prevalence and predictors of PPGP 12 years after delivery. Methods: This is a long-term follow-up study based on a previous cohort study that commenced in 2002. New questionnaire data 12 years postpartum were collected in 2014 and early 2015. The questionnaire was distributed to a total of 624 women from the initial cohort. Results: In total, 295 women (47.3%) responded to the questionnaire where 40.3% (n = 119) reported pain to a various degree and 59% (n = 174) reported no pain. Increased duration and/or persistency of pain, self-rated health, sciatica, neck and/or thoracic spinal pain, sick leave the past 12 months, treatment sought, and prescription and/or non-prescription drugs used were all associated with an statistically significant increase in the odds of reporting pain 12 years postpartum. Widespread pain was common and median expectation of improvement score was 5 on an 11-point numeric scale (interquartile range 2-7.50). More than one of five women (21.8%) reporting pain stated that they had been on sick leave the past 12 months and nearly 11% had been granted disability pension due to PPGP. No statistically significant differences were found between respondents and non-respondents regarding most background variables. Conclusions: This study is unique as it is one of few long-term follow-up studies following women with PPGP of more than 11 years. The results show that spontaneous recovery with no recurrences is an unlikely scenario for a subgroup of women with PPGP. Persistency and/or duration of pain symptoms as well as widespread pain appear to be the strongest predictors of poor long-term outcome. Moreover, widespread pain is commonly associated with PPGP and may thus contribute to long-term sick leave and disability pension. A screening tool needs to be developed for the identification of women at risk of developing PPGP to enable early intervention.

    Women's health in a rural setting in societal transition in Ethiopia.2001Inngår i: Social Science and Medicine, ISSN 0277-9536, E-ISSN 1873-5347, Vol. 53, nr 11, 1525-39 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    There are reports indicating a worsening of women's health in transitional rural societies in sub-Saharan Africa in relation to autonomy, workload, illiteracy, nutrition and disease prevalence. Although these problems are rampant, proper documentation is lacking. The objective of this study was to reflect the health situation of women in rural Ethiopia. Furthermore, the study attempts to address the socio-demographic and cultural factors that have potential influence on the health of women in the context of a low-income setting. A combination of qualitative and quantitative research methods was utilised. In-depth interviews and a cross-sectional survey of randomly selected women were the main methods employed. The Butajira Rural Health Program demographic surveillance database provided the sampling frame. Heavy workload, lack of access to health services, poverty, traditional practices, poor social status and decision-making power, and lack of access to education were among the highly prevalent socio-cultural factors that potentially affect the health of women in Butajira. Though the majority of the women use traditional healers younger women show more tendency to use health services. No improvement of women's status was perceived by the younger generation compared to the older generation. Female genital mutilation is universal with a strong motivation to its maintenance. Nail polish has replaced the rite of nail-extraction before marriage in the younger generation. As the factors influencing the health of women are multiple and complex a holistic approach should be adopted with emphasis on improving access to health care and education, enhancing social status, and mechanisms to alleviate poverty.
