- Background. Of the estimated one million Papanicolaou (pap) smears performed annually in Sweden, about 4% show any degree of abnormality. Approximately, 1% of these cases contain moderate or severe atypia (high-grade squamous intraepithelial lesions) and the rest contain low-grade atypia. Recommendations for the management of minor abnormalities vary in various parts of Sweden. Generally, a second Pap smear is obtained 4-6 months after the first one showing low-grade atypia. The aim of this study is to compare the sensitivity of human papilloma virus (HPV)-DNA testing for the detection of cervical intraepithelial neoplasia (CIN) 2-3 with that of a second Pap smear in women, who had low-grade atypia in their first Pap smear. Methods. Women with low-grade atypia in the Stockholm area, detected at a population-based cytology screening, were enrolled. A repeat Pap smear, HPV test, and colposcopically directed biopsies were obtained. For the detection of HPV, Hybrid Capture II (HC II) was used. Results. The HPV-DNA test was positive in 66% of the 177 participating women. The sensitivity of the second Pap smear and HPV-DNA test to detect CIN 2-3 was 61 (95% CI = 45-74) and 82% (95% CI = 67-91), respectively. The positive and negative predictive values of HPV testing were 27 (95% CI = 18-35) and 89% (95% CI = 80-97), respectively. Conclusions. In Sweden, a second Pap smear is often obtained for the follow-up of women with low-grade atypia. The results of our study show that compared to the second Pap smear, HPV testing with HC II is a more sensitive method for detecting high-grade lesions.

- Proteoglycans are well-known modulators of intercellular communication and signaling. Remodeling of the proteoglycans in the human uterus occurs throughout pregnancy, and during labor. We therefore hypothesize that heparan sulfate proteoglycans (HSPGs) play an important role in establishing normal labor. In this study HSPGs were characterized and localized in human uterine tissue. Uterine biopsies were obtained from four nonpregnant women, four women during elective cesarean section and four during emergency cesarean section. The biopsies were extracted using 4 mguanidinium hydrochloride (GuHCL). HSPGs were then purified by repeated ion-exchange chromatography on dehydroepiandrosterone (DEAE)-cellulose after digestion with chondroitinase ABC and finally precipitated with Alcian blue. HSPGs were identified by agarose gel electrophoresis and Western blotting. Controlled degradation of the heparan sulfate (HS) side-chains was performed using heparitinase or deglycosylation with trifluoromethanesulfonic acid (TFMS). The resulting core proteins were separated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) and visualized by Coomassie staining. HSPGs were localized in uterine tissue by immunohistochemistry. SDS-PAGE after deglycosylation indicated the presence of multiple distinct core proteins tentatively identified as syndecans 1-4 and glypican 1. Western blots confirmed the presence of these proteoglycans and also perlecan. Immunohistochemistry revealed that the HSPGs were localized mainly in the smooth muscle with few in the extracellular matrix (ECM). Syndecan 3, the dominant proteoglycan, showed the most pronounced changes during pregnancy and labor. For the first time several heparan sulfate proteoglycans have been identified and localized in the human uterus and shown to vary in expression during pregnancy and labor. Syndecan 3 had the most outstanding features in this respect.

Tidskriftsartikel (refereegranskat)abstract
- Background. Ethical issues arise in many obstetric situations and demand constant consideration by obstetricians. The aim of this study was to highlight the meaning of being in an ethically difficult situation as narrated by obstetricians. Methods. A descriptive design with a qualitative approach using a hermeneutic phenomenological method for analysis. Interviews were performed with 14 obstetricians working in a Swedish hospital setting. Results. The overriding theme was Sympathetic responsibility in the decisions of critical importance for the mother and her infant. Five related themes were to: (i) proceed with a moral reasoning that leads to the choice of a possible solution; (ii) balance one's own medical knowledge and moral insight with the needs and requests of the parents; (iii) be aware of one's medical and moral responsibility in relation to the decision made; (iv) experience the ability to take action and to make and carry out difficult and important decisions relating to the health of the mother and infant; and (v) reflect on a given situation in a manner leading to a rational acceptance of one's own conduct. Conclusions. Sympathetic responsibility is the structure of the meaning of the obstetricians' lived experience, which means that the obstetricians with the help of their medical knowledge and their desire to support the mother's autonomy do what is best for the mother and her infant. Implications include that an exchange of ethical thoughts and moral reasoning should lead to a higher degree of mutual understanding between colleagues and between the different professionals. Co-operation is important to achieve the best outcome for the mother and her infant.

- Objectives. To compare perinatal and infant mortality in breech and cephalic presentations and between planned vaginal and cesarean section (CS) breech deliveries in Sweden. Methods. The study comprised two parts. Study A is a national cohort study for the period 1991-2001, including 22 549 breech presentations and 875 249 cephalic presentations born at >= 38 completed weeks. Study B is a case-control study, including all 164 breech deliveries with perinatal or 1-year infant death (during 1991-1999 in Sweden) and controls. Results. Study A: Among non-malformed infants, the total mortality rate was 0.46% in breech and 0.28% in cephalic presentations [adjusted odds ratio (OR) 1.6; 95% confidence interval 1.3-1.9]. Non-malformed breech babies were at an increased risk of antenatal death (breech versus cephalic hazard ratio: 2.7, 2.1-3.6). The infant mortality among non-malformed breech deliveries was higher in vaginal birth than in delivery by CS before labor (OR 2.5, 1.2-5.3). The perinatal + infant mortality among non-malformed breech babies was higher at delivery after 39 completed weeks than at CS delivery at 38 weeks (0.53% versus 0.14%; OR 3.5, 1.9-6.4). The estimated needed number of CS to avoid one death was 400. Study B: In breech presentations without malformations, OR for perinatal or infant death was 3.1 (1.7-5.8) at planned vaginal delivery compared with planned CS delivery, and when breech presentations not diagnosed at 37 gestational weeks were excluded, OR was 3.7 (1.6-9.2). Conclusions. These large population-based and case-control studies both show a significant reduction of perinatal and infant mortality with planned CS in term breech pregnancy.

Tidskriftsartikel (refereegranskat)abstract
- Background. Deliveries among women who had an in vitro fertilization (IVF) are characterized by increased risks for both the mother and the infant/child. Part of these effects may be due to maternal characteristics. Methods. Using reports from all clinics performing IVF in Sweden, 12 186 women who gave birth after such procedures were identified (13 261 deliveries, 16 280 infants born). Various social and medical characteristics of the women were studied and compared with all women giving birth. Information was retrieved by interviews in early pregnancy or by linkage with various registers. Results. Women who had IVF were older than other women who gave birth and were older after standard IVF than after intracytoplasmatic sperm injection (ICSI). They were more often of first parity and smoked less than other delivered women. There were more women with high body mass index: they worked outside home less often and were more often of Swedish nationality. Women who had standard IVF had more previous miscarriages than expected, but this was not true for women who had ICSI. Their pattern of drug usage differed from that of other women who had given birth. Conclusions. Women who underwent IVF and gave birth showed marked deviations from other women who gave birth. Some of these characteristics may help to explain the increased risks associated with these procedures. Women who had ICSI were less deviating than women who had standard IVF. © Acta Obstet Gynecol Scand 2005.

Tidskriftsartikel (refereegranskat)abstract
- Background. Exercise is an important part of many women's lives. Women are often advised to refrain from physical exercise during pregnancy. The reason given is mainly safety, i.e. fear of maternal hyperthermia, which is known to be related to neural tube defects. However, exercise during pregnancy has not been shown to be related to hyperthermia. Objective. To study temperature and oxygen saturation responses to low-impact exercise in healthy pregnant women. Methods. Forty pregnant women and 11 controls participating in low-impact aerobic exercise were monitored before exercise, at maximum-exercise level, and after exercise with regard to core temperature, heart rate, and oxygen saturation level. Results. The core temperature among the pregnant women did not increase significantly at maximum exercise or after exercise (36.5 versus 36.7 or 36.5 °C, P = 0.1, P = 0.5). None of the pregnant women were even close to approaching a dangerous body temperature at an intensity level of 69% of their maximum heart rate. As compared with pre-exercise values, oxygen saturation among pregnant women was significantly reduced at both maximum-exercise and postexercise measurements, but no measurement was below 95% in oxygen saturation. Conclusion. Low-impact aerobics at about 70% of one's maximum heart rate appears to be safe in terms of risk of maternal hyperthermia.

Preterm birth in Sweden 1973-2001: rate, subgroups, and effect of changing patterns in multiple births, maternal age, and smoking
- 2005
-
Ingår i: Acta Obstet Gynecol Scand. - : Wiley. ; 84:6, s. 558-565
-
Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: The objectives of this report are to evaluate changes in the preterm birth rate in Sweden 1973-2001. Furthermore, describe the proportion of spontaneous and indicated preterm births and assess risk factors for the subgroups of preterm birth during the period from 1991 to 2001. METHODS: A population-based register study of all births occurring in Sweden from 1973 to 2001 registered in the Swedish Medical Birth Register was designed. The analysis of subgroups was restricted to the period 1991-2001. Gestational age was calculated using last menstrual period and best estimate. Odds ratio for preterm birth related to risk factors was calculated for the subgroups' spontaneous and indicated preterm birth. RESULTS: After an increase in the beginning of the 1980s, the preterm birth rate has decreased from 6.3% in 1984 to 5.6% in 2001 (P < 0.0001). The proportion of multiple births born preterm of the total birth rate increased from 0.34% in 1973 to 0.71% in 2001 (P < 0.0001). Spontaneous preterm births account for 55.2% and iatrogenic preterm births for 20.2% of all preterm births. The strongest association with maternal smoking in early pregnancy was found at gestational age <28 weeks and spontaneous preterm birth [odds ratio (OR) smoking versus no smoking: 1.55, 95% confidence intervals (CI): 1.42-1.69]. The strongest association for maternal age was found between gestational age <28 weeks and indicated preterm birth (OR 5-year increase: 1.34, 95% CI: 1.21-1.47). CONCLUSIONS: The preterm birth rate in Sweden has decreased since the mid 1980s. The composition of different subtypes of preterm birth in a Scandinavian low-risk population seems to be similar to populations with higher incidence of preterm birth and perinatal infections.

Tidskriftsartikel (refereegranskat)abstract
- In the past 20 years, a significant improvement has been shown in the treatment for infertility in both women and men through the development of in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI). Only donated sperm could be previously used for treatment; now oocytes can also be donated. Furthermore, the combination of IVF and ICSI with advanced genetic methods has made preimplantation genetic diagnosis possible for many genetic conditions. These methods enable genetic testing of the early human embryo by using only a single cell, one blastomere biopsied from the embryo, as the sample from which the diagnosis of many chromosome rearrangements and other inherited diseases can be made. It has also been established that a considerable proportion of infertility is caused by genetic defects, which have several implications for infertility treatment. The purpose of this review is to give a concise introduction on how genetics is involved in assisted reproduction technology to specialists who may not be working in this particular field of gynecology, but who would need some knowledge of this for proper care of their patients.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Sweden has the highest abortion numbers among the Nordic countries. Since 1995, the abortion rate among teenagers has increased by nearly 50%. We therefore undertook a study where the overall aim was to gain a deeper understanding on which factors female teenagers believe may explain the increasing numbers of teenage abortions. Teenagers' perceptions of teenage pregnancy, abortion, sexual behavior, and contraceptive habits were investigated. METHODS: Six focus group interviews with 17-year-old Swedish girls were conducted. The interviews were tape-recorded, transcribed verbatim, and analyzed by manifest content analysis. RESULTS: Negative attitudes toward teenage pregnancy and supportive attitudes toward abortion were expressed. Risk-taking behaviors such as negligence in contraceptive use and intercourse under the influence of alcohol were suggested as main reasons behind the increasing numbers of abortions among Swedish teenagers. The contemporary, sexualized, media picture was believed to influence adolescents' sexual behavior, and liberal attitudes toward casual sex were expressed. Girls were perceived as more obliged than boys in taking responsibility for contraceptive compliance and avoidance of pregnancy. The apprehension that hormonal contraceptives cause negative side-effects was widely spread, and the participants were found to have a somewhat limited knowledge of abortion. The majority were unsatisfied with the quality of sexual education provided by the schools. CONCLUSION: Possible reasons for increased abortion numbers among teenagers in Sweden could be liberal attitudes toward casual sex in combination with negligence in contraceptive use, use of alcohol followed by sexual risk-taking, fear of hormonal contraceptives, and a deterioration of sexual education in the schools.

Tidskriftsartikel (refereegranskat)abstract
- Background. The national recommendation in Sweden regarding number of antenatal care visits was reduced in 1996. The aim of this study was to explore the factors associated with number of visits made and with women’s own opinions about these visits. Another aim was to study associations between the number of visits and satisfaction with antenatal care overall.Methods. All Swedish-speaking women who came for their first visit to the midwife in 593 participating clinics during 3 weeks evenly spread over 1 year in 1999–2000 were invited to participate in the study. Information was collected by postal questionnaires after the booking visit and 2 months after childbirth. Cases of preterm delivery and intrauterine death were excluded. Results. After excluding miscarriages, non-Swedish-speaking women, and women booked at non-participating clinics, about 69% of all women booked in antenatal care were recruited. Of these, 2421 (83%) completed the two questionnaires. About 25% followed the standard visiting schedule for a normal pregnancy, 57% made more visits, and 17% fewer visits. The number of visits made was associated ith parity, medical diagnosis, depressive symptoms, level of education, and women’s preferences in early pregnancy. Women’s own opinion that they made too few visits was associated with a preference for more visits in early pregnancy and actually receiving fewer visits than the standard schedule. The view that they made too many visits was associated with a previous negative birth experience, a wish for fewer visits, having a medical diagnosis, many children, and major worries. The vast majority of women (87.6%) were satisfied with antenatal care overall but less with emotional (76.9%) than with medical (82.3%) aspects. No association was found between number of visits made and satisfaction, but women’s own opinion that they had too few visits was associated with dissatisfaction with medical as well as emotional aspects of care and the opinion that they made too many visits with the emotional aspects of care. Conclusion. Two-thirds of the women did not follow the standard visiting schedule, the the majority of women made more visits. The number of antenatal visits seemed to be fairly well adapted to women’s individual needs and, to some extent, to their own wishes. Very few women were dissatisfied with the number of visits made as well as the antenatal care overall.

- Background. The aim of this study is to investigate the long-term efficacy of the Burch colposuspension and to analyze the risk factors for an unsuccessful outcome at the long-term follow-up of more than 10 years. Methods. Data from patient files of 190 women on whom surgery was performed with Burch colposuspension during 1980-1988 and answers from a postal questionnaire performed median 14 years after the Burch colposuspension concerning the lower urinary tract function were retrieved retrospectively. Results. Subjectively significant urinary incontinence was experienced by 56% of the responders. Only 19% reported no incontinence episodes. Among the significant urinary incontinent women, symptoms of stress incontinence occurred in 26%, urge incontinence in 17%, and mixed incontinence in 42%. In 15%, the symptom of incontinence was atypical and could not be categorized. Feeling of incomplete bladder emptying post-operatively and pre-operative obesity was associated with the long-term outcome of Burch colposuspension (odds ratio (OR) = 2.33, 95% confidence interval (95% CI) = 1.20-4.54 and OR = 2.52, 95% CI = 1.10-5.77, respectively). Age, obesity at the long-term follow-up or having had surgery for fecal incontinence, genital prolapse, or hysterectomy were not significantly associated with the outcome of the Burch colposuspension. Conclusions. The subjective cure rate decreases with time after Burch colposuspension. Lower urinary tract symptoms are very common at the long-term after Burch colposuspension with more than three-fourth experiencing these. Feeling of incomplete bladder emptying post-operatively and pre-operative obesity seem to be long-term risk factors for an adverse outcome. A standard definition for follow-up periods is suggested. © Acta Obstet Gynecol Scand 2005.

- Objective. To evaluate the occurrence of voiding dysfunction and symptoms of genital prolapse at long-term follow-up after Burch colposuspension (Bc) in relation to the occurrence of the symptoms in an age-matched normal population. Materials and methods. A follow-up study of the 190 patients who underwent Bc in 1980-88 and 305 age-matched control women randomly selected from the general population. The participants answered a questionnaire in 1998 with detailed questions about the pelvic floor function. Univariate and multivariate analyses were performed. Results. The prevalence and frequency of urinary incontinence were significantly higher in the patient group compared with those in the control group as were urge incontinence, difficulty to start voiding, time needed at the toilet for voiding, the need to return to the toilet for emptying the bladder, feeling of incomplete emptying of the bladder, and limitation of social life because of the leakage. The symptoms of genital prolapse were significantly more common in the patient group in spite of a significantly larger proportion of genital prolapse surgery in this group. Parity, high body mass index, heavy lifting work, chronic pulmonary diseases, hiatus hernias, and hysterectomy were significantly more common in the patient group than among the controls. Conclusions. At long-term follow-up, patients exhibit substantial symptoms of pelvic floor dysfunction (PFD) concerning voiding dysfunction and symptoms of genital prolapse compared with a normal population. This highlights the importance and need of treating pelvic floor disorders in a comprehensive way. Scientific works with comprehensive studies of PFD are needed. © Acta Obstet Gynecol Scand 2005.

- Objective. To evaluate the prevalence of pelvic floor dysfunction (PFD) concerning bowel function at long-term follow-up after Burch colposuspension (Bc) in relation to the bowel function in an age-matched sample of women in the general population. Methods and material. This is a follow-up study of a cohort of 190 patients who underwent Bc in 1980-1988 and 305 age-matched control women without urinary anti-incontinence surgery, randomly selected from the general population. The participants answered a postal questionnaire with detailed questions about the pelvic floor function in 1998. Univariate and multivariate analyses were performed. Results. The patients showed considerable signs of bowel dysfunction compared with the general population in the following aspects: they used the fingers to help emptying the bowel [odds ratio (OR) 3.25 (1.35-7.86)], had feeling of incomplete emptying of the bowel [OR 2.29 (1.11-4.73)], felt no warning before passing a motion [OR 3.04 (1.20-7.71)], had gas incontinence [OR 1.98 (1.17-3.37), had loose stool incontinence [OR 3.67 (1.43-9.42)], used protection against fecal leakage during daytime [OR 3.22 (1.30-7.95)], and experienced that the bowel function affected the general well-being adversely [OR 2.15 (1.30-3.56)]. Conclusion. The patients who have undergone colposuspension for stress urinary incontinence have more symptoms of PFD concerning the bowel function than women without urinary anti-incontinence surgery in the general population. This affects the general well-being. A comprehensive concept of multidisciplinary assessment and treatment of PFD should be encouraged. © Acta Obstet Gynecol Scand 2005.

- AIM: The aim of this study is to find out how common miscarriages are among women who have delivered a child. METHODS: The numbers of deliveries and miscarriages were extracted from the Swedish Medical Birth Register between 1983 and 2003. Linear regression was performed in order to investigate whether the increasing mean age of mothers or differences in pregnancy identification methods could explain the increased frequency of miscarriage. RESULTS: The reported number of miscarriages increased each year during the 21-year period, with a marked increase between 1991 and 1993 and only a slight increase during the final 10 years. For primiparous women, the frequency of reported miscarriages per delivery increased from 8.6% in 1983 to 13.9% in 2003. The corresponding figures for 2-parous women showed an increase from 14.5% to 21.3% respectively. Women aged 30-34 years had an odds ratio of 1.43 (95% CI 1.40-1.45) to suffer spontaneous abortion compared to the age group 25-29 years. Linear regression showed that an increase in mean age at delivery could only partly explain the increase in the frequency of reported miscarriages. A possible explanation could be differences in methods of identifying early pregnancy. CONCLUSION: Of all women who deliver a child, nearly 20% have experienced previous miscarriage. The increased mean age of women could only explain a small portion of the seen increase in miscarriage. The marked increase from 1991 to 1993 is interesting. Possible reasons for the increase are discussed.

Tidskriftsartikel (refereegranskat)abstract
- Background: Women's grief after miscarriage is substantial and important. Women who experience early miscarriage do not constitute a homogenous group. The aim of this study is to measure whether a structured follow-up visit to a midwife (group 1) at 21-28 days after early miscarriage could reduce the women's grief, measured using the perinatal grief scale Swedish short version (PGS) after a further 3 months (i.e. 4 months after the miscarriage), compared to a regular follow-up visit to a midwife (group 2).Methods: We performed an open randomized study of women who experienced early miscarriage (n = 88). The midwife's attitude in group 1 came from Swanson science theory of midwifery. In group 2, the women were offered only the ordinary type of consultation at a regular visit. A questionnaire with the PGS was used in both groups. Four months after the miscarriage, a second questionnaire with the same perinatal grief scale was sent by post.Results: There was a 30% greater reduction in grief in group 1 than that in group 2, when comparing the first and second measurements (not significant). The biggest differences were in the subscales active grief and difficulty in coping. Women with the subdiagnosis missed abortions had, as a group, significantly higher PGS scores at both visits, especially in active grief and difficulty in coping, regardless of the type of follow-up visit.Conclusions: A structured follow-up visit did not, in comparison with a regular follow-up visit, imply any significant reduction in grief as measured using the PGS scale. However, the subgroup missed abortion had more extensive grief than the other women with miscarriage. Structured follow-up visits are not imperative for all women with early miscarriage.

- Background. Only scanty research exists about the relationship between women's expectations during pregnancy and their experiences as reported during the actual process of labor and afterwards. The aims of the present study were: 1. to investigate the associations between fear of childbirth during pregnancy and postpartum and fear and pain during early active labor (phase 1: cervix dilatation 3–5 cm), and 2. to explore possible differences regarding fear of childbirth during pregnancy and postpartum between women who did or did not receive epidural analgesia during labor.Methods. Fear of childbirth was measured in 47 nulliparous women during gestation weeks 37–39 by means of the Wijma Delivery Expectancy/Experience Questionnaire (W-DEQ version A). During early active labor we measured women's fear (Delivery Fear Scale) and their experiences of pain (a pain intensity scale). Finally, fear after childbirth (W-DEQ version B) was measured two hours, two days, and five weeks after delivery.Results. A positive correlation appeared between fear of childbirth during pregnancy, postpartum, and early active labor. There were no differences in fear of childbirth during late pregnancy between women who received epidural analgesia and those who did not. Postpartum fear was higher in the women who had received epidural analgesia.Conclusions. Pregnant women who fear childbirth are prone to report fear during the actual labor and postpartum. The administration of epidural analgesia is not a sufficient response to women's fear during the process of labor.

Comparison of ultrasound and autopsy findings in pregnancies terminated due to fetal anomalies
- 2006
-
Ingår i: Acta Obstetricia et Gynecologica Scandinavica. - : Wiley. - 0001-6349 .- 1600-0412. ; 85:10, s. 1208-1216

- Objective. To compare antenatal diagnoses with autopsy findings in pregnancies terminated after ultrasound detection of fetal anomalies. A second aim was to study the quality of antenatal fetal diagnosis over time. Design. Retrospective, multicenter study over two consecutive six-year periods in Uppsala and Stockholm. Setting. Cases were identified through fetal autopsy reports. Subjects. Three hundred and twenty-eight fetuses from pregnancies terminated between 1992 and 2003 because of ultrasonographically diagnosed anomalies. Main outcome measures. The findings at the last ultrasound examination were compared with the autopsy reports. Results. In 299 cases (91.2%) ultrasound findings either exactly matched or were essentially similar to the autopsy findings. In 23 cases (7%) ultrasound findings were not confirmed at autopsy, but the postnatal findings were at least as severe as the antenatal ones. In six cases (1.8%) termination was performed for an anomaly which proved to be less severe than was predicted by ultrasound. The number of such cases was the same in both six-year periods, while the total number of cases increased from 113 in the first to 215 in the second period. Fetal examination provided further diagnostic information in 47% of the cases. In 10% a syndrome was disclosed. Conclusion. Termination of pregnancy was not always based on a correct antenatal diagnosis. All fetuses but one from terminated pregnancies had evident anomalies. In six cases (1.8%) the decision to terminate was based on suboptimal prognostic and diagnostic information. Fetal autopsy by an experienced perinatal pathologist is essential to provide a definitive diagnosis.

Tidskriftsartikel (refereegranskat)abstract
- OBJECTIVES: To assess the ascertainment of spina bifida and cleft lip/palate (CLP) in newborns and in fetuses from terminated pregnancies (ToPs) in the Swedish Birth Defects Registry (BDR) and to estimate the true incidences of these two anomalies. DESIGN: Retrospective register study. SETTING: Center for Epidemiology at the Swedish National Board of Health and Welfare, and Uppsala University Hospital. POPULATION: Newborns and fetuses from ToPs with spina bifida (1999-2004) and CLP (1999-2002) in Sweden. METHODS: Data from four registries/sources were used to estimate ascertainment in BDR and incidences of spina bifida and CLP. Main outcome measure: Ascertainment, under-ascertainment, and true incidence. RESULTS: For newborns, under-ascertainment of spina bifida and CLP were 6 and 13%, respectively, in BDR after record linkage with the Medical Birth Registry. Ascertainment of cleft palate increased when accompanied by cleft lip. The under-ascertainment of spina bifida in ToPs after 18 gestational weeks was 27%. Ascertainment of CLP in all ToPs and of spina bifida in ToPs before the 18th gestational week could not be estimated. The majority (109/155, 70%) of ToPs with spina bifida occurred before the 18th week. The estimated incidence of spina bifida per 10,000 births was 6.1 (2.4 newborns and 3.7 ToPs) and of CLP 20.1 (18.9 newborns and 1.2 ToPs). CONCLUSION: The ascertainments are relatively high for newborns in BDR, but lower or unknown for ToPs, which has an impact on the surveillance of spina bifida in view of the high proportion of ToPs.

- Background. Description of incidence, clinical signs, symptoms, and consequences of eclampsia in Scandinavia, and assessment of substandard care and potential preventability. Methods. A descriptive cohort study including all women giving birth in a 2-year period (mid-1998-mid-2000) in Scandinavia. Notifications of eclampsia cases were obtained from all obstetric units at 3-monthly intervals. All patient files were reviewed, and systematic audit was performed to identify potentially preventable cases by using predefined criteria. Main outcome measures. Signs and symptoms preceding the eclamptic seizure, the standard of medical care, maternal and perinatal morbidity, and mortality were all recorded. Potentially preventable cases through improved care and cases eligible for primary prophylactic magnesium sulfate (MgSO4) were estimated. Results. The incidence of eclampsia was 5.0/10 000 maternities (CI = 4.3-5.7/ 10 000). Eighty-six percent had a diagnosis of pre-eclampsia before the seizure. Nine of 10 had at least one physical complaint before the first seizure, severe headache being the most common symptom, occurring in two-thirds. Most seizures (90%) occurred after admission to hospital. By audit, 89 cases (42%) were classified as having received substandard care. Prophylactic use of magnesium sulfate might have reduced the number of eclampsia cases by 35 (17%). Conclusions. Eclampsia occurred mainly in hospital and the majority of women had symptoms heralding the seizure. In retrospect, nearly half of the cases were found potentially preventable by timely intervention, improved medical care, and systematic use of prophylactic treatment with MgSO4.

- 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.

- 2006
-
Ingår i: Acta Obstet Gynecol Scand. - : Wiley. - 0001-6349. ; 85:8, s. 986-92

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: The aim was to describe the short- and long-term results of treatment for urinary incontinence (UI) in women using the tension-free vaginal tape (TVT) procedure at a single unit and to identify factors predictive of successful outcome. MATERIAL AND METHODS: Consecutive female patients (n = 707) treated for UI with the TVT procedure at Karlstad Hospital from November 1996 to June 2004 were included. After a standardized preoperative evaluation, the women were classified as having either stress urinary incontinence (SUI) or mixed urinary incontinence (MUI). The results of surgery were evaluated after 1, 2, and 5 years, by means of a postal questionnaire. An objective evaluation was performed after 5 years in a subsample of the first patients included (n = 59). Factors influencing the cure rate were analyzed using multiple regression analysis. RESULTS: The subjective cure rate was 83% after 1 year and 73% after 5 years. The objective cure rate was 83% in the subgroup after 5 years. Surgical time was 30+/-9 min (mean+/-SD). The rate of bladder perforations was 1.7%. In patients with MUI the cure rate was lower than in patients with SUI (after 5 years 54.9% versus 81.0%). Type of incontinence was the only independent variable found to influence surgical outcome. CONCLUSIONS: The TVT procedure, performed in over 700 women at a single gynecological unit, was found to be a safe and efficient surgical procedure. Type of incontinence was the only independent variable found to predict for outcome of surgery.

Forskningsöversikt (refereegranskat)abstract
- Objective. To assess the current knowledge concerning progestogen-only contraception (POC) and risks of venous thromboembolism (VTE). Design and setting. Systematic review of the literature on observational and analytical studies reporting risk estimates for VTE in women exposed to POCs. Methods and main outcome measures. We performed a computerized literature search in the Pub Med, Embase, and the Cochrane Library for studies published between 1966 and February 13, 2008. Based on the evaluated studies we calculated an overall risk estimate for VTE in association with POC. Results. Four case-control studies and one cohort study were included. Of the case-control studies, three reported an increased risk and one a decreased risk of VTE. The cohort study found divergent results depending on the type of statistical analysis used. None of the results was statistically significant. The overall odds ratio for POC-associated VTE in the four case-control studies was 1.45 (95% CI=0.92-2.26). Conclusions. The risk of VTE associated with use of POCs is poorly investigated. The slightly elevated overall risk estimate might suggest an association between POC and an increased risk for VTE. The results must, however, be interpreted with caution due to the possibility of residual confounding. Well-designed studies with sufficient statistical power to evaluate risks of VTE with POC are warranted.

Tidskriftsartikel (refereegranskat)abstract
- Background. The objective of this study was to investigate the attitudes towards and management of single embryo transfer (SET) among Nordic in vitro fertilisation (IVF) doctors, and to present the rate of SET and multiple pregnancies in the different countries. Methods. A questionnaire was sent to all IVF doctors in the Nordic countries (n=198, 78.5% responded). Pregnancy rates, SET and multiple births rates were extracted from registries. Main outcome measure was attitudes and management of SET. Results. Almost all doctors thought that a twin pregnancy compared unfavourably to a singleton. A twin rate >10% was acceptable for 5% of Swedish doctors. Corresponding figures for Finnish, Danish and Norwegian doctors were 21, 35 and 35%, respectively. For a woman <36 years, performing her first cycle and with two good quality embryos, almost all doctors would recommend SET. For a woman =36 years in a similar situation, SET would be recommended only in Sweden and Finland. The pregnancy rate per embryo transfer (ET), the SET rate 2003, the multiple birth rate, and the estimated SET rate 2004 were 33.3, 21.5, 22.7 and 25% (Denmark), 31.3, 43.4, 14 and 51% (Finland), 40.5, 10.5, 26.5 and 16% (Iceland), 30.6, 18, 25.2 and 26% (Norway), and 35.3, 55.1, 11.8 and 71% (Sweden). Conclusions. The SET and multiple birth rates reflect the attitudes of Nordic IVF doctors to SET and multiple births well. When introducing SET, the attitude of the IVF doctor seems to be important. © 2007 Taylor & Francis.

Ingår i: Acta Obstetricia et Gynecologica Scandinavica. - : Wiley. - 0001-6349 .- 1600-0412. ; 86:6, s. 671-677

Tidskriftsartikel (refereegranskat)abstract
- Background. Antenatal identification of infants small for gestational age (SGA) improves their perinatal outcome. Repeated measurements of the symphysis-fundus (SF) heights performed by midwives is the most widespread screening method for detection of SGA. However the insufficiency of this method necessitates improved practices. Earlier start and more frequent SF measurements, which could be acomplished by self-administered measurements, might improve the ability to detect deviant growth. The present study was set up to evaluate wether pregnant wome can reliable perform SF measurements by themself. Method. Forty healthy women with singelton and ultrasound-dated pregancies from 2 antenatal clinics in Uppsala, Sweden, were asked to perform 4 consecutive SF measureemnts once a week, from 20 to 25 weeks of gestation until delivery. The self-administered SF measurements were recorded and systematically compared with midwives' SF measurements. Results. Thirty-three pregnant women performed self-administered SF measurements over a 14-week period (range 1-21). The SF curves constructed from self-admiinistered SF measurements had the same shape as previously constructed population-based reference curves. The variance for self-admiinistered SF measurements was higher than that of the midwives. Conclusions. Pregnant women are capable of measuring SF heights by themselves, but with a higher individual variance than midwives. Repeated measurements at each occasion can compensate for the higher variance. The main advantage of self-administered SF measurements is the opportunity to follow fetal growth earlier and more frequently.

- Background. In Sweden measurements of the symphysis-fundus (SF) distance are used to detect small for gestational age (SGA) pregnancies. The aim of this study was to evaluate the efficiency of Swedish ultrasound-based SF reference curves in detecting SGA pregnancies. Methods. To assess the sensitivity for detection of SGA pregnancies we performed a case-control study. Through the Swedish Medical Birth Register we identified all singleton SGA infants born in Uppsala in 1993-1997 and randomly recruited non-SGA singleton infants as controls. We included 169 term and 73 preterm SGA cases and 296 controls, all born at term. The reference curves constructed by Steingrimsdottir (S curve) and Kieler (K curve) were evaluated. Gestational age at the first alarm in the preterm SGA group was recorded. Results. In term pregnancies the S curve showed a sensitivity of 32% and specificity of 90% at a cut-off of -2 SDs. The corresponding values for the K curve were 51% and 83%, respectively. In preterm SGA pregnancies the sensitivity of the S curve was 49% and of the K curve 58%. The first alarm below 2 SDs was noted before 32 weeks in 37% with the S curve and 43% with the K curve for preterm SGA pregnancies. Conclusions. Both tested Swedish SF reference curves had low sensitivities for term SGA pregnancies. Sensitivity was higher for the preterm group and SF measurements seem to be better for detecting the most severe cases of SGA.

- Background. Cigarette smoking during pregnancy is causally related to birthweight, but we do not know whether fetal growth restriction is a continuous process or, if not, at what stage of pregnancy it affects weight gain. Material and methods. A random sample of para 1 and 2 mothers, drawn from the population of pregnant women in Bergen and Trondheim, Norway, and Uppsala, Sweden, were examined by a detailed questionnaire concerning smoking habits, menstrual history and pregnancy dating, and subjected to morphometric sonography of their fetuses in or around week 17. Of the 547 study participants, 31.9% were smokers. Gestational age was primarily determined by the last menstrual period [LMP], except in those with irregular cycles, and in 30 cases (6.6% of those with regular cycles) in whom the biparietal diameter [BPD]-determined age deviated >14 days from the LMP-based date. Results. The analysis did not reveal any statistically significant differences between the fetuses of non-smokers, light smokers (0-9 cigarettes per day) and heavy (10+ cigarettes per day) smokers, regarding BPD, mean abdominal diameter [MAD] femur length [FL], and a 'body contour index': [BPD+FL]MAD. Conclusion. Tobacco-induced fetal growth restriction probably begins after gestational week 17.

Tidskriftsartikel (refereegranskat)abstract
- Objectives. To assess whether women with pre-eclampsia (PE) have different properties of the blood vessel wall compared to healthy pregnant controls. Further, to evaluate endothelial function and vascular mechanical properties in women with PE with special regard to its association with bilateral uterine artery notch and placental histopathology. Participants. Some 57 Caucasian pregnant women: 23 with uncomplicated pregnancies and normal uterine artery Doppler, and 34 with PE, the PE group comprising 2 subgroups according to the presence (n=20) or absence (n=14) of bilateral uterine artery notches. Methods. Ultrasonic echo-tracking assessed the elastic properties of the common carotid artery, abdominal aorta and popliteal artery. Flow-mediated dilatation (FMD) of the brachial artery was measured by ultrasonography. Histopathological examination of the placenta was carried out in 46 pregnancies: 18 uncomplicated pregnancies, 15 with PE with bilateral notch, and 13 with PE without bilateral notch. Results. There were no significant differences in carotid, aortic or popliteal vessel wall stiffness either between women with PE and controls or within the PE group. FMD was significantly lower in women with PE than in controls (p=0.03). The lowest FMD was observed in pre-eclamptic women with bilateral uterine artery notches 9.5% (SD: 5.3) compared to 11.6% (SD: 5.4) in pre-eclamptic women without bilateral uterine artery notch, and 13.4% (SD: 4.0) in controls (p=0.01). Bilateral uterine artery notching was significantly associated with a lower FMD (OR: 0.87, 95% CI: 0.77-0.98). There were significantly more placentas with high ischaemic score in the bilateral notch group than in the group with PE and normal circulation. Conclusions. There were no differences in vessel wall stiffness between women with PE and healthy controls. Women with PE showed signs of endothelial dysfunction, significantly more pronounced in women with bilateral uterine artery notch. Bilateral uterine artery notch was associated with ischaemic pathology of the placenta. Notwithstanding, a significant number of placentas in the PE group failed to show noteworthy ischaemic or other morphological changes that could explain the role of the placenta in the development of PE.

- Objective. To study whether increased maternal weight and other factors of importance is associated with higher birth weights of the children over a period of almost 25 years. Design. Retrospective cohort study. Setting. Delivery wards in southeast Sweden. Sample. A total of 4,330 delivered women and their children from the years 1978, 1986, 1992, 1997, and 2001. Methods. Analysis of covariance was used to evaluate the importance of the mothers body mass index (BMI) on the childrens birth weights during the study years and smoking, parity, employment, gestational age, and the age of the mothers were adjusted for. Main outcome measures. Weight of the offspring in relation to maternal BMI and possible confounders such as smoking, parity, employment, gestational age, and the age of the mother. Results. Between 1978 and 1992, there was an increase in birth weight in each of the four BMI categories (i.e. BMI20, 20-24.9, 25-29.9 and 30, respectively) even after adjustments were made for relevant background characteristics (p0.001). However, between 1992 and 2001, the birth weight for children whose mothers had a BMI of less than 20 or between 20 and 24.9 decreased (p0.001). For almost every study year, the mothers BMI was of significant influence on the childrens birth weights. However, the proportion of variance explained by the models (i.e. the adjusted R2) was not substantially altered when the mothers BMI was excluded from the models. Conclusion. Maternal BMI is of significance to explain trends in infants birth weight over time, but not of sole importance.

- Background. To determine the detection rate of fetal structural abnormalities by a routine 11-14-week ultrasound scan for dating in an unselected pregnant population. Methods. A prospective observational cohort study of 2,708 unselected pregnant women attending an abdominal ultrasound examination at 11-14 weeks gestation. The number of major fetal structural abnormalities diagnosed after birth was obtained from a computerized database at the same unit. Results. Out of 2,708 pregnant women, 89 (3.3%) were found to have a missed abortion at the time of the ultrasound scan and 33 (1.2%) were diagnosed as twins. Thirteen major structural abnormalities were detected, three cases of anencephaly (one case also had a spina bifida), one case with hydranencephaly, one fetus with Dandy-Walker syndrome, two cases with gastroschisis, one case with a bilateral hydronephrosis, one case with a generalized hydrops, one fetus with multiple malformations, and three cystic hygromas. An additional 19 major structural defects were detected at birth. Four cases of neural tube defects and nine fetuses with congenital heart defects were diagnosed. The antenatal ultrasound detection rate was 40.6% (13/32). Nine patients had a nuchal translucency greater than 3.0 mm (excluding cystic hygromas), two of them had chromosomal abnormalities (trisomy 21 and trisomy 18). Conclusions. Fetal structural abnormalities were detected in 41% (95%CI = 24-59) of the cases in an unselected pregnant population at a routine 11-14-week ultrasound scan for dating purpose. Two out of nine fetuses with a nuchal translucency greater than 3.0 mm had a chromosomal abnormality. © 2006 Taylor & Francis.
