    Deliveries among teenage women - with emphasis on incidence and mode of delivery: a Swedish national survey from 1973 to 20102013In: BMC Pregnancy and Childbirth, ISSN 1471-2393, E-ISSN 1471-2393, Vol. 13, no 204Article in journal (Refereed)
    Abstract [en]

    Background: Since the 1970-ies Sweden has actively developed strategies in social care, education and health care in order to counteract the negative consequences of adolescent parenthood. The aims of this study are to determine the annual incidence of singleton delivery among adolescents 1973-2010 and analyse obstetric and neonatal outcomes. Methods: A retrospective cohort study, using data from the Swedish Medical Birth Register was conducted. All singleton deliveries in Sweden between 1973 and 2010 were included. Totally 1,941,940 women had 3,761,576 deliveries during the period. Analyses of obstetric and neonatal outcome were restricted to 1992-2010. Adolescents were subdivided into three groups: less than16 years (n = 472), 16-17 years (n = 5376), 18-19 years (n = 23560). The reference group consisted of women age 20-30 years (n = 893505). Data were analysed using multivariate logistic regression models adjusted for confounding factors and presented as crude and adjusted odds ratios with 95% confidence interval. Results: The annual incidence of teenage births decreased significantly from 7.7 to 1.6%. Teenagers were more likely to deliver normally vaginally (aOR 1.70 (95% CI 1.64-1.75), less likely to have Caesarean section (aOR 0.61 (95% CI 0.58-0.64), and had a greater risk of delivering prematurely (less than 28 weeks)(aOR 1.61 (95% CI 1.31-2.00), but did not have more small-for-gestational-age babies (aOR 1.07 (95% CI 0.99-1.14). Risks of placenta previa, postpartum haemorrhage greater than 1000 ml and perineal rupture were significantly lower among teenagers. Although the rate with Apgar score less than 7 at 5 minutes was similar the teenagers neonates showed less fetal distress and meconium aspiration. Conclusion: Adolescent births have steadily decreased in Sweden. Adolescents were more likely to be delivered vaginally than the adult women. The risks for obstetric maternal complications for adolescents were lower than for adult women except for the risk of prematurity.

    Impact of maternal age on obstetric and neonatal outcome with emphasis on primiparous adolescents and older women: a Swedish Medical Birth Register Study2014In: BMJ Open, ISSN 2044-6055, E-ISSN 2044-6055, Vol. 4, no 11, e005840- p.Article in journal (Refereed)
    Abstract [en]

    Objectives: To evaluate the associations between maternal age and obstetric and neonatal outcomes in primiparous women with emphasis on teenagers and older women. Design: A population-based cohort study. Setting: The Swedish Medical Birth Register. Participants: Primiparous women with singleton births from 1992 through 2010 (N=798 674) were divided into seven age groups: less than17 years, 17-19 years and an additional five 5-year classes. The reference group consisted of the women aged 25-29 years. Primary outcome: Obstetric and neonatal outcome. Results: The teenager groups had significantly more vaginal births (adjusted OR (aOR) 2.04 (1.79 to 2.32) and 1.95 (1.88 to 2.02) for age less than17 years and 1719 years, respectively); fewer caesarean sections (aOR 0.57 (0.48 to 0.67) and 0.55 (0.53 to 0.58)), and instrumental vaginal births (aOR 0.43 (0.36 to 0.52) and 0.50 (0.48 to 0.53)) compared with the reference group. The opposite was found among older women reaching a fourfold increased OR for caesarean section. The teenagers showed no increased risk of adverse neonatal outcome but presented an increased risk of prematurity less than32 weeks (aOR 1.66 (1.10 to 2.51) and 1.20 (1.04 to 1.38)). Women with advancing age (greater than= 30 years) revealed significantly increased risk of prematurity, perineal lacerations, preeclampsia, abruption, placenta previa, postpartum haemorrhage and unfavourable neonatal outcomes compared with the reference group. Conclusions: For clinicians counselling young women it is of importance to highlight the obstetrically positive consequences that fewer maternal complications and favourable neonatal outcomes are expected. The results imply that there is a need for individualising antenatal surveillance programmes and obstetric care based on age grouping in order to attempt to improve the outcomes in the age groups with less favourable obstetric and neonatal outcomes. Such changes in surveillance programmes and obstetric interventions need to be evaluated in further studies.

    Mode of anesthesia and postoperative symptoms following abdominal hysterectomy in a fast-track setting2011In: Acta Obstetricia et Gynecologica Scandinavica, ISSN 0001-6349, E-ISSN 1600-0412, Vol. 90, no 4, 369-379 p.Article in journal (Refereed)
    Abstract [en]

    Objective. To determine whether postoperative symptoms differ between women who undergo abdominal benign hysterectomy in a fast-track model under general anesthesia or spinal anesthesia with intrathecal morphine. Design. Secondary analysis from a randomized, open, multicenter study. Setting. Five hospitals in south-east Sweden. Population. One-hundred and eighty women scheduled for benign hysterectomy were randomized; 162 completed the study; 82 were allocated to spinal and 80 to general anesthesia. Methods. The Swedish Postoperative Symptoms Questionnaire, completed daily for 1 week and thereafter once a week until 5 weeks postoperatively. Main Outcome Measures. Occurrence, intensity and duration of postoperative symptoms. Results. Women who had hysterectomy under spinal anesthesia with intrathecal morphine experienced significantly less discomfort postoperatively compared with those who had the operation under general anesthesia. Spinal anesthesia reduced the need for opioids postoperatively. The most common symptoms were pain, nausea and vomiting, itching, drowsiness and fatigue. Abdominal pain, drowsiness and fatigue occurred significantly less often and with lower intensity among the spinal anesthesia group. Although postoperative nausea and vomiting was reported equally in the two groups, vomiting episodes were reported significantly more often during the first day after surgery in the spinal anesthesia group. Spinal anesthesia was associated with a higher prevalence of postoperative itching. Conclusions. Spinal anesthesia with intrathecal morphine carries advantages regarding postoperative symptoms and recovery following fast-track abdominal hysterectomy.

    Cost-effectiveness of general anesthesia versus spinal anesthesia in fast track abdominal benign hysterectomy2011In: American Journal of Obstetrics and Gynecology, ISSN 0002-9378, E-ISSN 1097-6868, Vol. 205, no 4, 043- p.Article in journal (Refereed)
    Abstract [en]

    Objective: The study objective was to compare total costs for hospital stay and postoperative recovery for two groups of women who underwent fast track abdominal benign hysterectomy, one group under general anesthesia, the other under spinal anesthesia. Costs were evaluated in relation to health related quality of life.

    Study Design: Costs of treatment using data from a randomized multicenter study at five hospitals in Sweden were analyzed retrospectively. Of 180 women scheduled for benign abdominal hysterectomy; 162 were randomized for the study, 80 allocated to general anesthesia and 82 to spinal anesthesia.

    Results: Total costs (hospital costs plus costs reduced productivity costs) were lower for the spinal anesthesia group. Women who had spinal anesthesia had a faster recovery measured by health related quality of life and QALYs gained in postoperative month one.

    Conclusion: Use of spinal anesthesia for fast track benign abdominal hysterectomy was more cost-effective than general anesthesia.

    Health-related quality of life and postoperative recovery in fast-track hysterectomy2011In: Acta Obstetricia et Gynecologica Scandinavica, ISSN 0001-6349, E-ISSN 1600-0412, Vol. 90, no 4, 362-368 p.Article in journal (Refereed)
    Abstract [en]

    Objective. To determine whether health-related quality of life (HRQoL) and postoperative recovery of women who undergo abdominal hysterectomy in a fast-track program under general anesthesia (GA) differ from women who receive spinal anesthesia with intrathecal morphine (SA). Design. Secondary analysis from an open randomized controlled multicenter study. Setting. Five hospitals in south-east Sweden. Population. One hundred and eighty women admitted for abdominal hysterectomy for benign disease were randomized; 162 completed the study, 80 with GA and 82 with SA. Methods. The HRQoL was measured preoperatively using the EuroQoL EQ-5D and the Short-Form-36 health survey (SF-36) questionnaires. The EQ-5D was used daily for 1 week; thereafter, once weekly for 4 weeks and again 6 months after operation. The SF-36 was completed at 5 weeks and 6 months. Dates of commencing and ending sick leave were registered. Main Outcome Measures. Changes in HRQoL; duration of sick leave. Results. The HRQoL improved significantly faster in women after SA than after GA. Sick leave was significantly shorter after SA than after GA (median 22.5 vs. 28 days). Recovery of HRQoL and duration of sick leave were negatively influenced by postoperative complications. In particular, the mental component of HRQoL was negatively affected by minor complications, even 6 months after the operation. Conclusions. Spinal anesthesia with intrathecal morphine provided substantial advantages in fast-track abdominal hysterectomy for benign gynecological disorders by providing faster recovery and shorter sick leave compared with general anesthesia.

    Snabbspår har fördelar vid elektiv gynekologisk kirurgi.2014In: Läkartidningen, ISSN 0023-7205, E-ISSN 1652-7518, Vol. 111, no 25-26, 2-7 p.Article in journal (Refereed)
    Abstract [en]

    Fast-track is a multimodal strategy aimed at achieving an improved and accelerated postoperative recovery. The strategy combines unimodal evidence-based interventions concerning preoperative preparation, peroperative principles and postoperative care. There is substantial evidence for the benefits of following fast-track concepts in general elective surgery to enhance postoperative recovery. The main findings of this review are that there are benefits likewise within elective gynecological surgery, but studies of quality of life, patient satisfaction and health economics are needed. Studies of fast-track within non-elective surgery and gynaecological oncology surgery are lacking. Widespread information and education is needed to improve the rate of implementation of fast-track. Comprehensive involvement of the entire staff dealing with the patient in the perioperative period is crucial to ensure implementation and development of surgical care aiming for enhanced postoperative recovery.

    The impact of mode of anaesthesia on postoperative recovery from fast-track abdominal hysterectomy: a randomised clinical trial2011In: BJOG-AN INTERNATIONAL JOURNAL OF OBSTETRICS AND GYNAECOLOGY, ISSN 1470-0328, Vol. 118, no 3, 299-308 p.Article in journal (Refereed)
    Abstract [en]

    Objective To determine whether the duration of hospital stay after abdominal hysterectomy in a fast-track setting differed between women operated under general anaesthesia or in spinal anaesthesia with intrathecal morphine. Design An open randomised controlled multicentre study. Setting Five hospitals in the south-east of Sweden. Population One hundred and eighty women scheduled for benign hysterectomy were randomised: 162 completed the study, 82 were allocated to spinal anaesthesia and 80 were allocated to general anaesthesia. Methods Fast-track model comprising no use of sedatives for premedication, pre-emptive anti-emetic therapy, intravenous fluid restriction, analgesics based on non-opioids, early enteral nutrition and mobilisation, and standard criteria for discharge. Spinal anaesthesia with 20 mg hyperbaric bupivacaine and 0.2 mg morphine. General anaesthesia with propofol, fentanyl and rocuronium, and with continuous propofol and ventilation with oxygen-in-air for maintenance of anaesthesia. Main outcome measures Hospital stay, consumption of analgesics, vomiting, pruritus and bowel function recovery. Results Median hospitalisation did not differ significantly between women who had hysterectomy with spinal or general anaesthesia (46 and 50 hours, respectively). Spinal anaesthesia was associated with a significantly lower use of opioids and a faster recovery of bowel function, although vomiting and pruritus were more prevalent. Conclusions In a fast-track model the duration of hospitalisation after abdominal hysterectomy was andlt; 50 hours, independent of the mode of anaesthesia. Spinal anaesthesia reduced the need for postoperative morphine compared with general anaesthesia. In order to improve patient recovery after gynaecological surgery further studies based on fast-track programmes are needed.

    Differential expression of insulin and IGF-I receptors in human tissuesManuscript (preprint) (Other academic)
    Abstract [en]

    Insulin and IGF-I are related peptides with similar structure. They both signal via their cognate receptors, the insulin receptor (IR) and the insulin-like growth factor (IGF)-I receptor (IGF-IR).

    Our aim was to simultaneously measure the amount of insulin and IGF-I receptors in different human tissues and also the IR-A and IR-B isoforms to study tissue specific expression

    Renal artery intima-media, myometrium, skeletal muscle or liver tissue samples were obtained from patients undergoing surgery. IR, IGF-IR, IR-A and IR-B gene expression was investigated with real-time RT-PCR and expression of IR and IGF-IR protein was examined by Western blot and ELISA.

    Renal arteries and myometrium expressed the IGF-IR gene to a higher extent than the IR gene, liver expressed more IR than IGF-IR and skeletal muscle expressed almost equal amounts of both receptors. IR-B was the most abundant isoform in all tissues. With Western blot we could detect IR in skeletal muscle, liver and myometrium. With ELISA we found that, normalized to total protein, the highest levels of IGF-IR were found in renal arteries and myometrium and low levels in skeletal muscle and liver. The highest levels of IR were found in liver.

    In conclusion there is a large variation in the quantity and ratio of insulin receptors and IGF-I receptors expressed in different tissues, the extremes being arterial intima media with predominantly IGF-I receptors and liver with predominantly insulin receptors. This suggests that differential expression of insulin and IGF-I receptors is a key mechanism in regulation of growth and metabolism.

    Pelvic organ prolapse and anorectal manometry: a prospective study2012In: Urogynaecologia International Journal, ISSN 1121-3086, E-ISSN 2038-8314, Vol. 26, no 1, 12-16 p.Article in journal (Refereed)
    Abstract [en]

    The aim of this study was to evaluate associations between anal sphincter pressure and stage of prolapse and bowel and prolapse symptoms among women undergoing prolapse surgery and to determine whether anal sphincter pressure could predict symptomatic and anatomical outcomes of prolapse surgery. Fortytwo women with pelvic organ prolapse (POP) stage 2-3 were included in this prospective longitudinal study. Pre- and postoperative evaluation by means of a symptom questionnaire, clinical examination and anorectal manometry. The vaginal prolapse surgery included at the very least posterior colporrhaphy. Analysis of variance and covariance and logistic regression models were used for statistical analyses. The anal sphincter pressure at rest and squeeze was significantly lower in women with the symptom vaginal protrusion than in the women without the symptom. No associations were found between anal sphincter pressure and the extent or degree of prolapse or subjective and anatomical outcomes of POP surgery. The prolapse symptom vaginal protrusion is associated with a low anal sphincter pressure but the anal sphincter pressure does not seem to predict the outcome of POP surgery, neither regarding symptoms nor anatomy.

    Factors associated with symptoms of pelvic floor dysfunction six years after primary operation of genital prolapse2008In: Acta Obstetricia et Gynecologica Scandinavica, ISSN 0001-6349, E-ISSN 1600-0412, Vol. 87, no 9, 910-915 p.Article in journal (Refereed)
    Abstract [en]

    Objective: To determine prevalence of pelvic floor dysfunction (PFD) symptoms in women six years after primary pelvic organ prolapse (POP) surgery and analyze predictive factors for these symptoms. DESIGN: Cross-sectional observational study.

    Setting: Three Swedish hospitals.

    Sample: Women who underwent primary POP surgery in 1993 and had no subsequent POP surgery during the following six years.

    Methods: Clinical data from patient records and a postal questionnaire concerning symptoms of PFD completed in 1999.

    Main outcome measures: Prevalence of PFD symptoms, predictive factors.

    Results: Urinary incontinence episodes > or =weekly were reported by 41%, feeling of vaginal bulging by 18% and solid stool incontinence by 15%. Thirty nine percent were sexually active; 15% refrained completely from sexual activity because of own discomfort or pain and 46% had no sexual activity due to lack of or sick partner. Discomfort or pain during sexual activity was experienced by 42%. Previous incontinence surgery and urinary incontinence prior to POP surgery were predictive factors for urinary incontinence. Anterior repair was protective for the postoperative symptoms of incomplete bladder and bowel emptying and vaginal bulging. Posterior repair was a risk factor for incomplete bowel emptying and solid stool incontinence. The association between posterior repair and discomfort or pain during sexual activity was not significant.

    Conclusion: The prevalence of PFD symptoms six years after primary POP surgery seemed high. The extent of POP surgery was predictive for postoperative symptoms of urinary and bowel dysfunction but not for discomfort or pain during sexual activity.

    Genital prolapse surgery after a shift in treatment tradition: an analysis of subsequent prolapse surgery2008In: Acta Obstetricia et Gynecologica Scandinavica, ISSN 0001-6349, E-ISSN 1600-0412, Vol. 87, no 4, 449-456 p.Article in journal (Refereed)
    Abstract [en]

    Objective: To determine whether the shift in treatment tradition of genital prolapse surgery was followed by a change in the occurrence of subsequent prolapse surgery, and to analyze the complementary and recurrent surgery with respect to the size of the prolapse and the extent of the primary surgery.

    Methods: A retrospective study of patients consecutively operated with primary prolapse surgery in three Swedish hospitals in two time periods: 261 patients in 1983 (Period I) and 281 patients in 1993 (Period II). Clinical data were obtained from the patient records. A follow-up period of 6 years was used for both periods.

    Results: Subsequent prolapse surgery was seen significantly more often in Period II than in Period I (7.7 versus 2.7%), and after selective repairs compared with complete repairs (7.7 versus 3.2%). Despite a significant reduction in the use of posterior repair between the time periods, no significant increase was seen in complementary posterior repairs compared with complementary repair in any of the other compartments. Size of the prolapse at the primary surgery or hysterectomy did not seem to influence the occurrence of subsequent prolapse surgery. The postoperative complication rate was significantly higher after complete repairs than after selective repair, and especially when posterior repair was included in the operation.

    Conclusion: Subsequent prolapse surgery is slightly more common after selective repair than after complete repair. However, selective repairs are encumbered with a lower complication rate. The results of this study appear to be in favor of a restrictive use of 'prophylactic' posterior repair.

    Primary surgery of genital prolapse: a shift in treatment tradition.2006In: Acta Obstetricia et Gynecologica Scandinavica, ISSN 0001-6349, E-ISSN 1600-0412, Vol. 85, no 9, 1104-1108 p.Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: The use of complete repairs in genital prolapse surgery has been questioned because of the possible adverse effects of the surgery on the urogenital and sexual function and selective repairs have been advocated. The aims of this study were to establish information about genital prolapse surgery and to analyze whether a shift from extensive prolapse surgery with complete repairs to selective repairs occurred during a 10-year period.

    METHODS: A retrospective study of 610 consecutive patients operated upon for genital prolapse during 1983 (Period I) and 1993 (Period II) in a sample of three Swedish hospitals was conducted. Data were obtained from the patient records. 542 women had primary surgery and were analyzed with emphasis on demographic, clinical, and surgical data.

    RESULTS: The demographic and clinical data of the patients showed no significant differences between the two periods. In Period I, 69% of the patients underwent complete repair compared with 37% in Period II (p<0.001). The proportion of prolapse operations without posterior colporrhaphy increased significantly from the first to the second period from 14 to 43% (p<0.001).

    CONCLUSION: The surgery for genital prolapse seems to have changed from complete repairs towards selective repairs and posterior colporrhaphy was more often avoided in the second period. The implication of this shift in surgical treatment on pelvic floor function is not known. Further studies are needed to disclose the effect of the surgery on pelvic floor function and dysfunction in the long term.

    Obstetric anal sphincter rupture in older primiparous women: A case-control study2006In: Acta Obstetricia et Gynecologica Scandinavica, ISSN 0001-6349, E-ISSN 1600-0412, Vol. 85, no 10, 1252-1258 p.Article in journal (Refereed)
    Abstract [en]

    Objective. To determine if maternal age (35 years of age or older) in primiparous women is a risk factor for the development of obstetric anal sphincter rupture (OASR) and to identify obstetric factors associated with it. Material and methods. This is a retrospective case-control study. The study population was made up of the 5,345 primiparous women aged 24-45 years who delivered vaginally with singleton live-born neonates during 1990-99 at the Department of Obstetrics and Gynecology, Linköping University Hospital, Sweden. As cases the 327 primiparous women aged 35-45 years at delivery were selected. For each case two primiparous controls ten years younger were selected, matched for gestational age and year of delivery, in all 654 controls. Maternal, obstetrical, and neonatal data were obtained from the delivery records. Obstetric factors for the development of OASR were assessed with multivariate logistic regression analysis. Results. No significant association was found between the primiparous age category and OASR. Vacuum extraction, forceps delivery, and the head circumference of the neonate were found to be independent risk factors for OASR, while the use of mediolateral episiotomy or epidural analgesia were independent protective factors for developing OASR. Conclusions. Primiparous women, 35 years of age or older, do not seem to have a greater risk of OASR than younger primiparous women. Risk factors for OASR are instrumental vaginal delivery and the size of the neonate. Mediolateral episiotomy and epidural analgesia seem to reduce the risk for OASR. © 2006 Taylor & Francis.

    Long-term outcome of porcine skin graft in surgical treatment of recurrent pelvic organ prolapse. An open randomized controlled multicenter study2011In: Acta Obstetricia et Gynecologica Scandinavica, ISSN 0001-6349, E-ISSN 1600-0412, Vol. 90, no 12, 1393-1401 p.Article in journal (Refereed)
    Abstract [en]

    Objective. To determine the long-term objective and subjective outcomes of use of a porcine skin graft (Pelvicol(TM)) compared with conventional colporrhaphy in recurrent pelvic organ prolapse surgery and to analyze risk factors and safety. Design. Open randomized controlled multicenter study. Setting. Eight Swedish hospitals. Population. 135 consecutive women with recurrent cystocele and/or rectocele admitted for vaginal prolapse surgery; 132 completed the study, 64 were randomly allocated to receive conventional colporrhaphy and 68 to Pelvicol. Methods. Conventional anterior and posterior colporrhaphy and colporrhaphy with use of Pelvicol(TM) mesh reinforcement. Clinical evaluation by means of pelvic organ prolapse quantification (POP-Q) and symptom questionnaire preoperatively, three months and three years postoperatively. Main outcome measures. Anatomical and subjective outcome.? Recurrence was defined as POP-Q=stage 2. Results. At three-month follow-up, early recurrence/surgical failures occurred significantly more often in the Pelvicol(TM) group, but at the three-year follow-up the recurrence rates were similar. The recurrence rates in the anterior compartment were 5762% and 4423% in the posterior compartment for the colporrhaphy and Pelvicol(TM) groups, respectively. Symptoms were substantially and equally reduced in the two groups after surgery. Sexual activity and function did not seem to be affected adversely in any group. The complication rate was low. Risk factors for anatomical recurrence were age, body mass index and preoperative stage of the prolapse. Conclusions. With the surgical technique used in this study, Pelvicol(TM) did not provide advantages over conventional colporrhaphy in recurrent pelvic organ prolapse concerning anatomical and subjective outcomes.

    Population-based study of survival for women with serous cancer of the ovary, fallopian tube, peritoneum or undesignated origin - on behalf of the Swedish gynecological cancer group (SweGCG).2017In: Gynecologic Oncology, ISSN 0090-8258, E-ISSN 1095-6859, Vol. 144, no 1, 167-173 p.Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE: The aim of the study was to determine survival outcome in patients with serous cancer in the ovary, fallopian tube, peritoneum and of undesignated origin.

    METHODS: Nation-wide population-based study of women≥18years with histologically verified non-uterine serous cancer, included in the Swedish Quality Registry for primary cancer of the ovary, fallopian tube and peritoneum diagnosed 2009-2013. Relative survival (RS) was estimated using the Ederer II method. Simple and multivariable analyses were estimated by Poisson regression models.

    RESULTS: Of 5627 women identified, 1246 (22%) had borderline tumors and 4381 had malignant tumors. In total, 2359 women had serous cancer; 71% originated in the ovary (OC), 9% in the fallopian tube (FTC), 9% in the peritoneum (PPC) and 11% at an undesignated primary site (UPS). Estimated RS at 5-years was 37%; for FTC 54%, 40% for OC, 34% for PPC and 13% for UPS. In multivariable regression analyses restricted to women who had undergone primary or interval debulking surgery for OC, FTC and PPC, site of origin was not independently associated with survival. Significant associations with worse survival were found for advanced stages (RR 2.63, P<0.001), moderate (RR 1.90, P<0.047) and poor differentiation (RR 2.20, P<0.009), neoadjuvant chemotherapy (RR1.33, P<0.022), residual tumor (RR 2.65, P<0.001) and platinum single (2.34, P<0.001) compared to platinum combination chemotherapy.

    CONCLUSION: Survival was poorer for serous cancer at UPS than for ovarian, fallopian tube and peritoneal cancer. Serous cancer at UPS needs to be addressed when reporting and comparing survival rates of ovarian cancer.

    Short-Term Overeating Induces Insulin Resistance in Fat Cells in Lean Human Subjects2009In: Molecular medicine (Cambridge, Mass. Print), ISSN 1076-1551, E-ISSN 1528-3658, Vol. 15, no 7-8, 228-234 p.Article in journal (Refereed)
    Abstract [en]

    Insulin resistance and type 2 diabetes (T2D) are closely linked to obesity. Numerous prospective studies have reported on weight gain, insulin resistance, and insulin signaling in experimental animals, but not in humans. We examined insulin signaling in adipocytes from lean volunteers, before and at the end of a 4-wk period of consuming a fast-food, high-calorie diet that led to weight gain. We also examined adipocytes from patients with T2D. During the high-calorie diet, subjects gained 10% body weight and 19% total body fat, but stayed lean (body mass index = 24.3 kg/m2) and developed moderate systemic insulin resistance. Similarly to the situation in T2D subjects, in subjects on the high-calorie diet, the amount of insulin receptors was reduced and phosphorylation of IRS1 at tyrosine and at serine-307 (human sequence, corresponding to murine serine-302) were impaired. The amount of insulin receptor substrate protein-1 (IRS1) and the phosphorylation of IRS1 at serine-312 (human sequence, corresponding to murine serine-307) were unaffected by the diet. Unlike the T2D subjects, in subjects on the high-calorie diet, likely owing to the ongoing weight-gain, phosphorylation of MAP-kinases ERK1/2 became hyperresponsive to insulin. To our knowledge this study is the first to investigate insulin signaling during overeating in humans, and it demonstrates that T2D effects on intracellular insulin signaling already occur after 4 wks of a high-calorie diet and that the effects in humans differ from those in laboratory animals.

    Insulin resistance in human adipocytes occurs downstream of IRS1 after surgical cell isolation but at the level of phosphorylation of IRS1 in type 2 diabetes2005In: The FEBS Journal, ISSN 1742-464X, E-ISSN 1742-4658, Vol. 272, no 1, 141-151 p.Article in journal (Refereed)
    Abstract [en]

    Insulin resistance is a cardinal feature of type 2 diabetes and also a consequence of trauma such as surgery. Directly after surgery and cell isolation, adipocytes were insulin resistant, but this was reversed after overnight incubation in 10% CO2 at 37 °C. Tyrosine phosphorylation of the insulin receptor and insulin receptor substrate (IRS)1 was insulin sensitive, but protein kinase B (PKB) and downstream metabolic effects exhibited insulin resistance that was reversed by overnight incubation. MAP-kinases ERK1/2 and p38 were strongly phosphorylated after surgery, but was dephosphorylated during reversal of insulin resistance. Phosphorylation of MAP-kinase was not caused by collagenase treatment during cell isolation and was present also in tissue pieces that were not subjected to cell isolation procedures. The insulin resistance directly after surgery and cell isolation was different from insulin resistance of type 2 diabetes; adipocytes from patients with type 2 diabetes remained insulin resistant after overnight incubation. IRS1, PKB, and downstream metabolic effects, but not insulin-stimulated tyrosine phosphorylation of insulin receptor, exhibited insulin resistance. These findings suggest a new approach in the study of surgery-induced insulin resistance and indicate that human adipocytes should recover after surgical procedures for analysis of insulin signalling. Moreover, we pinpoint the signalling dysregulation in type 2 diabetes to be the insulin-stimulated phosphorylation of IRS1 in human adipocytes.

    “A challenge” – healthcare professionals' experiences when meeting women with symptoms that might indicate endometriosis2016In: Sexual & Reproductive HealthCare, ISSN 1877-5756, E-ISSN 1877-5764, Vol. 7, 65-69 p.Article in journal (Refereed)
    Abstract [en]

    Objective

    The aim of the study was to identify and describe the experiences of healthcare professionals when meeting women with symptoms that might indicate endometriosis.

    Methods

    Semi-structured interviews were conducted with 10 gynecologists, six general practitioners and nine midwives working at one university hospital, one central hospital, one private gynecology clinic and five healthcare centers in south-east Sweden. The interviews were recorded and transcribed verbatim and analyzed using qualitative conventional content analysis.

    Results

    Three clusters were identified: the corroborating encounter, the normal variation of menstruation cycles, and the suspicion of endometriosis. The healthcare professionals tried to make a corroborating encounter by acknowledging the woman, taking time to listen, and giving an explanation for the problems. Healthcare professionals had different ways to determine what was normal as regards menstrual pain, ovulation pain and dyspareunia. They also needed to have the competence to act and react when the symptoms indicated endometriosis.

    Conclusions

    Meeting women with symptoms that might indicate endometriosis is challenging and demands a certain level of competence from healthcare professionals. Sometimes the symptoms are camouflaged as “normal” menstruation pain, making it hard to satisfy the needs of this patient group.

    Long-term efficacy of Burch colposuspension: A 14-year follow-up study2005In: Acta Obstetricia et Gynecologica Scandinavica, ISSN 0001-6349, E-ISSN 1600-0412, Vol. 84, no 8, 767-772 p.Article in journal (Refereed)
    Abstract [en]

    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.

    Impact of stress coping capacity on recovery from abdominal hysterectomy in a fast-track programme: a prospective longitudinal study2012In: British Journal of Obstetrics and Gynecology, ISSN 1470-0328, E-ISSN 1471-0528, Vol. 119, no 8, 998-1007 p.Article in journal (Refereed)
    Abstract [en]

    Objective To evaluate the effect of stress coping capacity in combination with mode of anaesthesia on postoperative recovery in fast-track abdominal hysterectomy. Design Prospective longitudinal study. Setting Five hospitals in the south-east of Sweden. Population A cohort of 162 women undergoing fast-track abdominal hysterectomy for benign conditions. Methods Self-administered questionnaires, the Stress Coping Inventory (SCI) and the Swedish Postoperative Symptom Questionnaire (SPSQ), and clinical information were collected prospectively. Stress coping capacity was categorised as high or low according to the summed score of the SCI. Comparisons of effect variables were adjusted using a propensity score-matching model. Main outcome measures Associations between stress coping capacity and hospital stay, sick leave, use of analgesic and self-reported postoperative symptoms. Results Women with high stress coping capacity had a significantly shorter sick leave, experienced postoperative symptoms significantly less often, and with lower intensity, than women with low stress coping capacity. With the exception of symptom intensity, these findings were related to having had the operation under spinal anaesthesia as opposed to general anaesthesia. Hospital stay, use of analgesics and abdominal pain were not related to stress coping capacity. Conclusions In patients for whom spinal anaesthesia was applied, high stress coping seems to be a quality that helps patients manage the burden of surgery. It is desirable for the individual, as well as for the healthcare system, to enhance recovery by using intervention programmes designed to improve or manage stress coping, particularly for individuals with low stress coping capacity. This recommendation merits further investigation.

    Individualiserad behandling vid ovarialcancer kan bli möjlig2015In: Läkartidningen, ISSN 0023-7205, E-ISSN 1652-7518, Vol. 112, no 50, 2281-3 p.Article in journal (Refereed)
    Abstract [en]

    Epithelial ovarian cancer (EOC) is the most lethal gynecologic malignancy in developed countries. Several promising steps toward individualized therapy have been taken recently due to increased knowledge of molecular biology. Multidisciplinary conferences for treatment planning and the centralization to tertiary surgical centers improve quality of surgery and survival. The primary treatment of EOC is radical surgery followed by adjuvant chemotherapy with carboplatin and paclitaxel. Bevacizumab added to the chemotherapy and used as maintenance treatment is standard in the primary treatment of patients with residual tumor or inoperable patients. The PARP inhibitor olaparib is recommended as maintenance treatment of women with platinum sensitive relapsed BRCA mutated high-grade serous EOC who have responded to platinum-based chemotherapy. BRCA testing should be offered to women with EOC. In platinum-resistant recurrence addition of bevacizumab to chemotherapy should be considered.

    Vaginal cleansing and postoperative infectious morbidity in vaginal hysterectomy. A register study from the Swedish National Register for Gynecological Surgery2011In: ACTA OBSTETRICIA ET GYNECOLOGICA SCANDINAVICA, ISSN 0001-6349, Vol. 90, no 1, 63-71 p.Article in journal (Refereed)
    Abstract [en]

    Objective. To evaluate whether preoperative vaginal preparation routines influence postoperative infectious morbidity in vaginal hysterectomy and to analyze risk factors for postoperative infectious morbidity. Design. Retrospective, longitudinal cohort study. Setting. Forty -three hospitals in Sweden, participating in the Swedish National Register for Gynecological Surgery. Population. All 6,496 women who were enrolled in the Register and underwent vaginal or laparoscopically assisted vaginal hysterectomy between 1 January 2000 and 1 February 2008. Methods. Register data were collected prospectively using doctors forms and patient questionnaires. Information about vaginal preparation routines in the clinics were achieved retrospectively by an e-mail survey. Multiple logistic regression analyses models were used to determine associations and risk factors. Main outcome measures. Infectious morbidity within 6-8 weeks postoperatively. Results. No significant differences were seen in postoperative infectious morbidity in long term between vaginal preparation using saline or chlorhexidine solution or no cleansing. At discharge from hospital, those who had had vaginal cleansing using saline solution had a significantly higher risk of postoperative infections. Risk factors for infectious morbidity were young age, obesity, peroperative injury of the urinary bladder, operative time and duration of hospital stay. Protective were prophylactic antibiotics and concomitant prolapse surgery. Conclusions. Saline solution should not be used for vaginal cleansing due to a higher risk of infectious morbidity in the immediate postoperative period. Infectious morbidity may be reduced further by employing preventive measures such as meticulous surgical technique, preoperative weight reduction in obese women and minimizing time in hospital.

    The influence of preoperative vaginal cleansing on postoperative infectious morbidity in abdominal total hysterectomy for benign indications2009In: ACTA OBSTETRICIA ET GYNECOLOGICA SCANDINAVICA, ISSN 0001-6349, Vol. 88, no 4, 408-416 p.Article in journal (Refereed)
    Abstract [en]

    Objective. To evaluate whether vaginal cleansing reduces the risk of postoperative infection after abdominal total hysterectomy on benign indications and to analyze risk factors. Design. Retrospective cohort study. Setting. All clinics including patients in the Swedish National Register for Gynecological Surgery. Population. All 7,193 women who underwent abdominal total hysterectomy for benign indications from 2000 to 2007. Methods. Information on clinic routines for preoperative vaginal cleansing was obtained retrospectively in a postal survey. Associations between routines for vaginal cleansing and structured data from the Register were analyzed by means of multivariate logistic regression models. The main effect variable was postoperative infections defined as infections treated with antibiotics within six to eight weeks postoperatively, reported by the patient or the physician. Main outcome measures. Prevalence and risk factors for postoperative infections. Results. Prevalence of postoperative infections was 14.4%. The prevalence did not differ between those having had vaginal cleansing using chlorhexidine and those without vaginal cleansing, whereas using saline solution was encumbered with a significantly increased risk. Risk factors for postoperative infections were age 60, obesity, smoking, weight of the uterus, duration of hospital stay, blood transfusion, and peroperative injury of the urinary bladder or ureter. Conclusion. Vaginal cleansing using chlorhexidine solution did not reduce the risk of postoperative infections, whereas vaginal cleansing using saline solution seemed to increase the risk. Some risk factors for postoperative infectious morbidity seem to be preventable.

    The Impact of Quality of Sleep on Recovery from Fast-Track Abdominal Hysterectomy2012In: Journal of Clinical Sleep Medicine (JCSM), ISSN 1550-9389, E-ISSN 1550-9397, Vol. 8, no 4, 395-402 p.Article in journal (Refereed)
    Abstract [en]

    Study Objectives: To examine the impact of mode of anesthesia on perceived quality of sleep and to analyze the perceived quality of sleep in affecting recovery from surgery. less thanbrgreater than less thanbrgreater thanMethods: A randomized, controlled, open multicenter trial was conducted in 5 hospitals in Southeast Sweden. One-hundred eighty women scheduled for fast-track abdominal hysterectomy for benign conditions were randomized to spinal anesthesia or general anesthesia; 162 women completed the trial; 82 allocated to spinal anesthesia and 80 to general anesthesia. Symptoms and perceived quality of sleep after surgery were registered daily in the Swedish Postoperative Symptoms Questionnaire. less thanbrgreater than less thanbrgreater thanResults: Women in the general anesthesia group experienced bad quality of sleep the night after surgery significantly more often than the women who had spinal anesthesia (odds ratio [OR] 2.45; p = 0.03). This was almost exclusively attributed to a significantly higher consumption of opioids postoperatively in the general anesthesia group. Risk factors for bad quality of sleep during the first night postoperatively were: opioids (OR 1.07; p = 0.03); rescue antiemetics (OR 2.45; p = 0.05); relative weight gain (OR 1.47; p = 0.04); summary score of postoperative symptoms (OR 1.13; p = 0.02); and stress coping capacity (OR 0.98; p = 0.01). A longer hospital stay was strongly associated with a poorer quality of sleep the first night postoperatively (p = 0.002). less thanbrgreater than less thanbrgreater thanConclusions: The quality of sleep the first night after abdominal hysterectomy is an important factor for recovery. In fast-track abdominal hysterectomy, it seems important to use anesthesia and multimodal analgesia reducing the need for opioids postoperatively and to use strategies that diminish other factors that may interfere negatively with sleep. Efforts to enhance quality of sleep postoperatively by means of preventive measures and treatment of sleep disturbances should be included in fast-track programs.

    Abdominal urethrocystopexy using fibrin sealant. A prospective study of long-term efficacy2000In: International Urogynecology Journal, ISSN 0937-3462, E-ISSN 1433-3023, Vol. 11, no 2, 93-96 p.Article in journal (Refereed)
    Abstract [en]

    Over the past decade efforts have been made to develop less invasive surgical treatment for female stress urinary incontinence (SUI). Abdominal urethrocystopexy with fibrin sealant combined with a couple of absorbable sutures has previously been reported as a promising method. This prospective observational study was aimed at evaluating the efficacy and safety of abdominal urethrocystopexy through a minilaparotomy using solely fibrin sealant (Tisseel) as the fixation glue. Forty-three women with objectively proven SUI were operated upon with this method. The subjective cure rates at 1 and 3 years' follow-up were 72% and 55%, respectively. The corresponding objective cure rates were 64% and 60%. No serious major operative complications occurred. One patient had transient urinary retention for 3 months. Otherwise, micturition was established within a median 1 day (range 1-3 days) after the operation. The result of this pilot study indicates a cure rate lower than that obtained with the conventional abdominal Burch colposuspension. Thus the method cannot be recommended as a standard procedure for treatment of SUI.

    Pelvic floor dysfunction after Burch colposuspension - A comprehensive study. Part I2005In: Acta Obstetricia et Gynecologica Scandinavica, ISSN 0001-6349, E-ISSN 1600-0412, Vol. 84, no 9, 894-901 p.Article in journal (Refereed)
    Abstract [en]

    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.

    Abstract [en]

    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.

    Lymphedema after treatment for endometrial cancer - A review of prevalence and risk factors2017In: European Journal of Obstetrics, Gynecology, and Reproductive Biology, ISSN 0301-2115, E-ISSN 1872-7654, Vol. 211, 112-121 p.Article, review/survey (Refereed)
    Abstract [en]

    Lymphedema is one of the least studied complications of cancer treatment and a chronic condition with a substantial impact on health-related quality of life (HQoL). Lymphedema of the legs (LLL) constitutes a common adverse side effect of lymphadenectomy LA in gynecologic cancer treatment. Primary treatment of endometrial cancer (EC) comprises hysterectomy and bilateral salpingo-oophorectomy. Pelvic and para-aortic lymphadenectomy is recommended in prognostic high risk groups of EC. This review summarizes the published literature concerning the prevalence of LLL after treatment for EC, methods used for measuring LLL, risk factors and HQoL impact. The main findings are that the reported prevalence of LLL varies significantly between 0% and 50%. This is due to a lack of a generally accepted standardization of terminology in assessment of lymphedema. The studies use different methods to assess and grade lymphedema and often the methodology used for determining LLL is poorly described and lacks baseline measurement. Lymphadenectomy, number of lymph nodes removed, and radiation therapy seems to increase the risk for LLL. All studies dealing with HQoL show that women with LLL have impaired HQoL. The level of evidence in the published studies is generally low. Consequently it is difficult to make clear-cut conclusions about the true prevalence or determination of risk factors. More prospective longitudinal or randomized trials with LLL as the primary outcome are necessary before conclusions can be drawn regarding prevalence of LLL and risk factor determination in EC. An internationally accepted standardization for terminology and methodology in lymphedema in research is needed. (C) 2017 Elsevier B.V. All rights reserved.

    Single-dose tranexamic acid in advanced ovarian cancer surgery reduces blood loss and transfusions: double-blind placebo-controlled randomized multicenter study2014In: Acta Obstetricia et Gynecologica Scandinavica, ISSN 0001-6349, E-ISSN 1600-0412, Vol. 93, no 4, 335-344 p.Article in journal (Refereed)
    Abstract [en]

    ObjectiveTo determine whether single-dose tranexamic acid given intravenously immediately before surgery for presumed advanced ovarian cancer reduces perioperative blood loss and blood transfusions. DesignA randomized double-blind, placebo-controlled multicenter study. SettingTwo university hospitals and two central hospitals in the southeast health region of Sweden. PopulationOne hundred women with presumed advanced ovarian cancer scheduled for radical debulking surgery between March 2008 and May 2012 who complied with inclusion/exclusion criteria were randomized; 50 were allocated to receive tranexamic acid and 50 to receive placebo. Analysis was performed according to intention-to-treat principles. MethodsThe volume of tranexamic acid (15mg/kg body weight, 100mg/mL tranexamic acid) or the same volume of placebo (0.9% NaCl) was added to a 100-mL saline solution plastic bag. The study medication was given immediately before the start of surgery. Data were analyzed by means of non-parametric statistics and multivariate models adjusted for confounding factors. Main outcome measuresBlood loss and red blood cell transfusions. ResultsThe total blood loss volume and transfusion rate were significantly lower in the tranexamic acid group compared with the placebo group. Median total blood loss was 520 and 730mL, respectively (p=0.03). Fifteen (30%) and 22 (44%), respectively received transfusions (odds ratio 0.44; upper 95% CI 0.97; p=0.02). ConclusionA single dose of tranexamic acid given immediately before surgery reduces blood loss and transfusion rates significantly in advanced ovarian cancer surgery. Tranexamic acid may be recommended as standard prophylactic treatment in advanced ovarian cancer surgery.

    Adipokines and Vascular Endothelial Growth Factor in Normal Human Breast Tissue in Vivo - Correlations and Attenuation by Dietary Flaxseed2016In: Journal of mammary gland biology and neoplasia, ISSN 1083-3021, E-ISSN 1573-7039, Vol. 21, no 1-2, 69-76 p.Article in journal (Refereed)
    Abstract [en]

    Exposure to sex steroids increases the risk of breast cancer but the exact mechanisms are yet to be elucidated. Events in the microenvironment are important for carcinogenesis. Diet containing phytoestrogens can affect the breast microenvironment and alter the risk of breast cancer. It has previously been shown that estrogen regulates extracellular levels of leptin, adiponectin, and VEGF in normal breast tissue in vivo. Whether these proteins correlate in breast tissue in vivo or if diet addition of flaxseed, a major source of phytoestrogens in Western diets, alters adipokine levels in breast tissue are unknown. We used microdialysis to sample proteins of normal human breast tissue and abdominal subcutaneous fat in situ in 34 pre-and postmenopausal women. In vitro, co-culture of breast cancer cells and primary human adipocytes was used. In vivo, in normal breast tissue, a significant positive correlation between VEGF and leptin was detected. No correlations were found in fat tissue. Co-culture of adipocytes and breast cancer cells per se increased the secretion of VEGF and leptin and enhanced the effects of estradiol compared to culture of either cell type alone. In vitro, inhibition of VEGF diminished the release of leptin while inhibition of leptin had no influence on VEGF secretion. The levels of leptin decreased and adiponectin increased after a dietary addition of 25 g of flaxseed/day for one menstrual cycle. We conclude that VEGF and leptin correlate significantly in normal human breast tissue in vivo and that dietary addition of flaxseed affect adipokine levels in the breast.

    Correlation between vascular endothelial growth factor and leptin in normal human breast tissue in vivo2015Manuscript (preprint) (Other academic)
    Abstract [en]

    Introduction: Events in the microenvironment are important for carcinogenesis of the breast. Adipocytes, which produce adipokines with paracrine effects, are the most abundant cell type in breast tissue. Exposure to sex steroids affects the risk of breast cancer. It has previously been shown that estrogen regulates the extracellular levels of leptin, adiponectin, IL-1β, and VEGF in normal human breast tissue in vivo.

    Objective: We aimed to determine if there were any relationships between leptin, adiponectin, IL-1β, and/or VEGF in normal human breast tissue in vivo and to elucidate the role of adipocytes in the regulation of these factors.

    Design and methods: Microdialysis was used to sample proteins of normal human breast tissue and abdominal subcutaneous (s.c.) fat in situ in pre-and postmenopausal women. An in vitro co-culture model of breast cancer cells and primary mature human adipocytes was used.

    Results: In vivo, in normal breast tissue, significant positive correlations between VEGF and leptin, and VEGF and leptin/adiponectin ratio were detected. No correlations were found in s.c. abdominal fat tissue. Co-culture of adipocytes and breast cancer cells per se increased the secretion of VEGF and leptin and enhanced the effects of estradiol compared to culture of either cell type alone. In vitro, inhibition of VEGF diminished the release of leptin while inhibition of leptin had no influence on VEGF secretion. In breast tissue, significant correlations between IL-1β and leptin and VEGF were revealed.

    Conclusions: Our results suggest that VEGF regulates leptin in normal human breast tissue. Moreover, physical contact between adipocytes and breast cancer cells, induces phenotypic changes and enhances the effects of estradiol. These mechanisms may be involved in breast cancer progression.

    Risk factors for postoperative complications after fast-track abdominal hysterectomy2012In: Australian and New Zealand journal of obstetrics and gynaecology, ISSN 0004-8666, E-ISSN 1479-828X, Vol. 52, no 2, 113-120 p.Article in journal (Refereed)
    Abstract [en]

    Background: Fast-track regimen has been shown to reduce postoperative complications in gastrointestinal surgery. less thanbrgreater than less thanbrgreater thanAims: We investigated the incidence and type of postoperative complications and associated risk factors after benign abdominal hysterectomy undertaken in a fast-track program. less thanbrgreater than less thanbrgreater thanMethods: A prospective longitudinal cohort study. In five Swedish hospitals, a cohort of 162 women, ASA 1-2, undergoing abdominal hysterectomy in a fast-track program was prospectively studied. Surgery was performed under spinal or general anaesthesia. The fast-track concept was standardised with discharge criteria and a restricted intravenous fluid regimen. Complications were systematically registered during the five-week follow-up period. Risk factors for complications were analysed using multiple logistic regression models. less thanbrgreater than less thanbrgreater thanResults: Forty-one (25.3%) developed postoperative complications, mainly infection and wound healing complications. The majority of the complications developed after discharge and were treated in the outpatient clinics. Four women (2.5%) were readmitted to hospital. Substantial risk factors for postoperative complications were obesity (OR 8.83), prior laparotomy (OR 2.92) and relative increase in body weight on the first postoperative day (OR 1.52). less thanbrgreater than less thanbrgreater thanConclusions: Minor infection and wound healing complications seem to be common in healthy women undergoing abdominal hysterectomy in a fast-track program. Obesity is an important risk factor also in fast-track abdominal hysterectomy. A modest increase in postoperative relative weight gain during the first postoperative day seemed to increase the risk of postoperative complications. This factor merits further study. Randomised studies are necessary to determine the impact of fast-track program and perioperative fluid regimens on postoperative complications.

    POP-Q measurements and symptoms of PFD.

    Results

    Follow-up time was a median of 11.3 years. Less than 3% had stage-3 prolapse. No significant difference was found in the presence of stage-2 or higher stage prolapse between the two hysterectomy groups (39% in SH versus 37% in TH; OR 1.28, 95% CI 0.59–2.80). Nor was there any significant difference in the quality-of-life measurement between the SH and TH groups [summary score PFDI-20: median 93 (range 60–201) versus 87 (range 60–186); Fisher's protected least significant difference post hoc test, = 0.78 ). None of the symptoms of PFD revealed statistically significant differences between the hysterectomy groups.

    Conclusions

    This long-term follow-up study of PFD showed basically no significant differences in subjective or objective measurements of POP, or in specific pelvic floor quality-of-life aspects after SH and TH. However, because of the low statistical power the results are inconclusive. Larger trials, and probably also a longer follow-up period, are necessary.

    A one‐year follow‐up of psychological well‐being after subtotal and total abdominal hysterectomy‐ a randomised study2010In: BJOG-AN INTERNATIONAL JOURNAL OF OBSTETRICS AND GYNAECOLOGY, ISSN 1470-0328, Vol. 117, no 4, 479-487 p.Article in journal (Refereed)
    Abstract [en]

    Objective: To compare subtotal abdominal hysterectomy (SH) and total abdominal hysterectomy (TH) regarding influence on postoperative psychological well‐being and surgical outcome measurements.

    Design: A prospective, open, randomised multicenter trial.

    Setting: Seven hospitals and one private clinic in the south‐east of Sweden. Population: 200 women scheduled for abdominal hysterectomy for benign conditions were enrolled in the study; 179 women completed the study (94 SH and 85 TH).

    Methods: Four different psychometric tests measuring general well‐being, depression and anxiety preoperatively, six and 12 months postoperatively. Statistical analysis of variance and covariance were used. Main outcome measures: Effects of operating method on psychological well‐being postoperatively. Analysis of demographic, clinical and surgical data including peri‐ and postoperative complications and complaints at follow‐up.

    Results: No significant differences were observed between the two groups in any of the psychometric tests. Both surgical methods were associated with a significantly higher degree of psychological well‐being six and 12 months postoperatively compared with preoperatively. The operating time was significantly longer for TH than SH. No significant differences were found in the clinical measures including complications. A substantial number of women experienced persistent cyclic vaginal bleedings after SH. Neither minor or major postoperative complications nor serum concentration of sex hormones were associated with the psychological general well‐being 12 months after the operation. Conclusions: General psychological well‐being is equally improved after both SH and TH within 12 months after the operation and does not seem to be associated with occurrence of perioperative complications or serum concentration of sex hormones.

    Attitudes to mode of hysterectomy--a survey-based study among Swedish gynecologists2009In: Acta obstetricia et gynecologica Scandinavica, ISSN 1600-0412, Vol. 88, no 3, 267-74 p.Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE: To determine gynecologists' attitudes to mode of hysterectomy on benign indication. DESIGN: Cross-sectional study. SETTING: Sweden. POPULATION: Members of the Swedish Society of Obstetrics and Gynecology. METHODS: A postal questionnaire. Questions examined attitudes to mode of hysterectomy based on three clinical scenarios with different conditions of the uterus. Gynecologists were also asked to estimate how the distribution of the different modes of benign hysterectomy should be overall. The modes to choose were total abdominal, subtotal abdominal, laparoscopic or vaginal hysterectomy (VH). Analyses were performed with multiple logistic regression and multivariate analysis of covariance. MAIN OUTCOME MEASURES: Preferred mode of hysterectomy in the three scenarios and distribution of modes of hysterectomy. RESULTS: VH was the most preferred method in general as well as when the uterus was of normal size, whereas subtotal and total abdominal hysterectomy were the most favored methods when the uterus was enlarged. VH was more often preferred by male compared to female gynecologists as a personal preference. The choice and distribution of mode varied significantly between place of work, seniority and in the quantity of yearly performed hysterectomies. The minimal invasive methods, vaginal and laparoscopic hysterectomy, were recommended in more than 50% of the overall suggested distribution. CONCLUSION: Personal choice of mode of hysterectomy does not seem to strictly follow evidence-based recommendations, but varies significantly between gynecologist's gender, type of clinical setting in which the gynecologist works, seniority and by how many hysterectomies the gynecologist does annually.

    Factors associated with postoperative recovery after laparoscopic and abdominal hysterectomy2008In: European Journal of Obstetrics, Gynecology, and Reproductive Biology, ISSN 0301-2115, E-ISSN 1872-7654, Vol. 140, no 1, 108-113 p.Article in journal (Refereed)
    Abstract [en]

    OBJECTIVES: To determine whether the day-by-day recovery of general wellbeing was faster in women undergoing laparoscopic hysterectomy than in total abdominal hysterectomy and to analyse the association between stress coping and sick-leave and the day-by-day recovery measured as general wellbeing.

    STUDY DESIGN: A randomised multicentre trial conducted in five hospitals in the South East of Sweden. Hundred and twenty-five women scheduled for hysterectomy for benign conditions were enrolled in the study and 117 women completed the study. Fifty-five women were randomised to abdominal hysterectomy and 62 to laparoscopic hysterectomy. Day-by-day recovery of general wellbeing was measured by a visual analogue scale 1 week preoperatively, 35 days postoperatively, and during 1 week 6 months postoperatively. Stress-coping capability was measured preoperatively using a specific psychometric measurement. Sick-leave was granted with an initial period of 14 days and prolonged on patient demand with 7 days periods. Effects of operating method and stress-coping ability on the day-by-day recovery adjusted for postoperative complications and analgesics were analysed by means of analysis of variance for repeated measurements.

    RESULTS: No significant difference was found in the day-by-day recovery of the general wellbeing between the operating methods. Stress-coping ability did significantly influence the day-by-day recovery of general wellbeing. Duration of sick-leave was associated with the occurrence of postoperative complications but not with stress-coping ability.

    CONCLUSIONS: The day-by-day recovery of general wellbeing is not faster in laparoscopic hysterectomy than in abdominal hysterectomy. Women with high stress-coping abilities have a better outcome in general wellbeing than women with low stress-coping capacity. Identification of women with low stress-coping abilities and prevention of complications might be of benefit for improving postoperative wellbeing.

    Psychological wellbeing after laparoscopic and abdominal hysterectomy--a randomised controlled multicentre study2006In: British Journal of Obstetrics and Gynecology, ISSN 1470-0328, E-ISSN 1471-0528, Vol. 113, no 9, 1023-30 p.Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE: To compare laparoscopic hysterectomy and abdominal total hysterectomy regarding influence on postoperative psychological wellbeing and surgical measures. DESIGN: A prospective, open, randomised multicentre trial.

    SETTING: Five hospitals in the South East of Sweden.

    POPULATION: Hundred and twenty-five women scheduled for hysterectomy for benign conditions were enrolled in the study, and 119 women completed the study. Fifty-six women were randomised to abdominal hysterectomy and 63 to laparoscopic hysterectomy.

    METHODS: Psychometric tests measuring general wellbeing, depression and anxiety preoperatively and 5 weeks and 6 months postoperatively.

    MAIN OUTCOME MEASURES: Effects of operating method on the psychological wellbeing postoperatively. Analysis of data regarding operating time, peroperative and postoperative complications, blood loss, hospital stay and recovery time.

    RESULTS: No significant differences in the scores were observed between the two groups in any of the four psychometric tests. Both the surgical methods were associated with a significantly higher degree of psychological wellbeing 5 weeks postoperatively compared with preoperatively. The operating time was significantly longer for the laparoscopic hysterectomy group, but the duration of the stay in hospital and sick-leave were significantly shorter for laparoscopic hysterectomy group compared with the abdominal hysterectomy group.

    CONCLUSIONS: General psychological wellbeing is equal after laparoscopic and abdominal hysterectomy within 6 months after the operation. The advantages of the laparoscopic hysterectomy are the shorter stay in hospital and shorter sick-leave, but these issues must be balanced by a longer duration of the operation.

    Short‐term recovery after subtotal and total abdominal hysterectomy ‐ a randomised clinical trial2010In: BJOG-AN INTERNATIONAL JOURNAL OF OBSTETRICS AND GYNAECOLOGY, ISSN 1470-0328, Vol. 117, no 4, 469-478 p.Article in journal (Refereed)
    Abstract [en]

    Objective: To determine whether the day‐byday postoperative recovery differs between women undergoing subtotal and total abdominal hysterectomy and to analyse factors associated with postoperative recovery and sick‐leave.

    Design: A prospective, open, randomised multicenter trial.

    Setting: Seven hospitals and one private clinic in the south‐east of Sweden.

    Population: 200 women scheduled for hysterectomy for benign conditions were enrolled in the study and 178 women completed the study. 94 women were randomised to subtotal abdominal hysterectomy and 84 to total abdominal hysterectomy.

    Methods: Day‐by day recovery of general well‐being measured by a visual analogue scale in a diary seven days preoperatively and 35 days postoperatively. Psychometric measurements included depression, anxiety and general psychological well‐being.

    Main outcome measures: Effects of operating method and preoperative well‐being on the day‐by‐day recovery and sick‐leave duration.

    Results: No significant difference was found in the day‐by‐day recovery between operating methods. Day‐by‐day recovery of general well‐being and duration of sick‐leave was strongly associated with the occurrence of minor complications but not with major complications. The level of psychological wellbeing preoperatively was strongly associated with the day‐by‐day recovery of general wellbeing and duration of sick‐leave.

    Conclusions: Day‐by‐day recovery of general well‐being is not faster in subtotal versus total abdominal hysterectomy. Independent of operation method there is an interaction between preoperative psychological wellbeing, postoperative recovery of general wellbeing and duration of sick‐leave. Postoperative complications and preoperative psychological well‐being are strong determinants for duration of sick‐leave. There is a need for intervention studies with focus on complications and preoperative well‐being.

    Systems-wide Experimental and Modeling Analysis of Insulin Signaling through Forkhead Box Protein O1 (FOXO1) in Human Adipocytes, Normally and in Type 2 Diabetes2016In: Journal of Biological Chemistry, ISSN 0021-9258, E-ISSN 1083-351X, Vol. 291, no 30, 15806-15819 p.Article in journal (Refereed)
    Abstract [en]

    Insulin resistance is a major aspect of type 2 diabetes (T2D), which results from impaired insulin signaling in target cells. Signaling to regulate forkhead box protein O1 (FOXO1) may be the most important mechanism for insulin to control transcription. Despite this, little is known about how insulin regulates FOXO1 and how FOXO1 may contribute to insulin resistance in adipocytes, which are the most critical cell type in the development of insulin resistance. We report a detailed mechanistic analysis of insulin control of FOXO1 in human adipocytes obtained from non-diabetic subjects and from patients with T2D. We show that FOXO1 is mainly phosphorylated through mTORC2-mediated phosphorylation of protein kinase B at Ser(473) and that this mechanism is unperturbed in T2D. We also demonstrate a cross-talk from the MAPK branch of insulin signaling to stimulate phosphorylation of FOXO1. The cellular abundance and consequently activity of FOXO1 are halved in T2D. Interestingly, inhibition of mTORC1 with rapamycin reduces the abundance of FOXO1 to the levels in T2D. This suggests that the reduction of the concentration of FOXO1 is a consequence of attenuation of mTORC1, which defines much of the diabetic state in human adipocytes. We integrate insulin control of FOXO1 in a network-wide mathematical model of insulin signaling dynamics based on compatible data from human adipocytes. The diabetic state is network-wide explained by attenuation of an mTORC1-to-insulin receptor substrate-1 (IRS1) feedback and reduced abundances of insulin receptor, GLUT4, AS160, ribosomal protein S6, and FOXO1. The model demonstrates that attenuation of the mTORC1-to-IRS1 feedback is a major mechanism of insulin resistance in the diabetic state.

    Obstetric Outcomes in Adolescents Related to Body Mass Index and Compared with Low-Risk Adult Women2017In: Journal of Women's Health, ISSN 1540-9996, E-ISSN 1931-843X, Vol. 26, no 5, 426-434 p.Article in journal (Refereed)
    Abstract [en]

    Objective: To evaluate in adolescents the association between body mass index (BMI) and obstetric outcomes and to determine whether the outcomes in the BMI groups of adolescents differ from those of a low-risk population of adult women. Materials and Methods: This is a nationwide population-based register study. Obstetric outcomes of 31,386 singleton primiparous adolescents were evaluated in relation to BMI classes. Furthermore, the outcomes of the adolescents and 178,844 normal weight, nonsmoking, singleton primiparous women, 25-29 years old with no known comorbidity, defined as standard women, were compared. Multiple logistic regression models were used. Results are presented as crude odds ratios (ORs) or adjusted ORs and with a 95% confidence interval. Results: Compared with normal weight adolescents, obese adolescents had a lower chance of a normal vaginal delivery (VD)76% versus 85% [adjusted OR 0.61 (0.55-0.68)], a higher risk for acute cesarean section (CS)8.9% versus 4.5% [adjusted OR 2.45 (2.08-2.88)], and stillbirth0.7% versus 0.2% [adjusted OR 3.17 (1.74-5.77)]. Compared with standard women, overweight adolescents had a higher chance of a normal VD82% versus 75% [crude OR 1.53 (1.44-1.64)] and a lower risk for acute CS6.3% versus 7.1% [crude OR 0.85 (0.76-0.95)]. Obese adolescents had a lower risk for instrumental VD8% versus 13% [crude OR 0.61 (0.53-0.71)] and obstetric anal sphincter injury1% versus 3% [crude OR 0.38 (0.26-0.57)]. Conclusion: Several adverse obstetric outcomes were obesity related among adolescents. Overweight adolescents seemed to have better obstetric outcomes than standard women, something to consider when optimizing resources for women during pregnancy and delivery.

    Phosphorylation of IRS1 at Serine 307 in Response to Insulin in Human Adipocytes Is Not Likely to be Catalyzed by p70 Ribosomal S6 Kinase2013In: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 8, no 4Article in journal (Refereed)
    Abstract [en]

    The insulin receptor substrate-1 (IRS1) is phosphorylated on serine 307 (human sequence, corresponding to murine serine 302) in response to insulin as part of a feedback loop that controls IRS1 phosphorylation on tyrosine residues by the insulin receptor. This in turn directly affects downstream signaling and is in human adipocytes implicated in the pathogenesis of insulin resistance and type 2 diabetes. The phosphorylation is inhibited by rapamycin, a specific inhibitor of mammalian target of rapamycin (mTOR) in complex with raptor (mTORC1). The mTORC1-downstream p70 ribosomal protein S6 kinase (S6K1), which is activated by insulin, can phosphorylate IRS1 at serine 307 in vitro and is considered the physiological protein kinase. Because the IRS1 serine 307-kinase catalyzes a critical step in the control of insulin signaling and constitutes a potential target for treatment of insulin resistance, it is important to know whether S6K1 is the physiological serine 307-kinase or not. We report that, by several criteria, S6K1 does not phosphorylate IRS1 at serine 307 in response to insulin in intact human primary adipocytes: (i) The time-courses for phosphorylation of S6K1 and its phosphorylation of S6 are not compatible with the phosphorylation of IRS1 at serine 307; (ii) A dominant-negative construct of S6K1 inhibits the phosphorylation of S6, without effect on the phosphorylation of IRS1 at serine 307; (iii) The specific inhibitor of S6K1 PF-4708671 inhibits the phosphorylation of S6, without effect on phosphorylation of IRS1 at serine 307. mTOR-immunoprecipitates from insulin-stimulated adipocytes contains an unidentified protein kinase specific for phosphorylation of IRS1 at serine 307, but it is not mTOR or S6K1.

    Isolated primary human visceral fat cells release more angiotensin II than subcutaneous adipocytesManuscript (preprint) (Other academic)
    Abstract [en]

    Background. Visceral obesity relates strongly to the metabolic syndrome and hence to hypertension. Although a local renin-angiotensin-system (RAS) in fat tissue is known, very few studies have dealt with RAS in isolated primary human fat cells, in particular from the visceral compartment.

    Methods. Measurement of angiotensin II (Ang II) in medium from isolated primary human fat cells from visceral and subcutaneous adipose tissues and analyses of RAS-components in human fat cells and fat tissues.

    Results. Primary human fat cells from omental adipose tissue produced more Ang II than subcutaneous cells. Treatment with insulin did not affect Ang II production and body-massindex of the fat-donors was unrelated to Ang II production. The PPAR gamma agonist rosiglitazone inhibited Ang II production in both types of isolated fat cells while addition of the Ang II receptor antagonist eprosartan inhibited the production in only subcutaneous fat cells. Addition of 50 or 200 nM of Ang II inhibited the PPAR gamma response elementactivity (PPRE-activity) in visceral, but not in the subcutaneous adipocytes.

    Conclusions. Since high PPRE-activity induced by rosiglitazone inhibited the Ang II production, it is possible that reduced PPRE-activity in the visceral human fat cells, demonstrated by us earlier, can explain the comparatively high Ang II production in these cells. This could form the basis for a local paracrine viscous circle in visceral fat where low PPRE-activity increases Ang II production that is further enhanced by Ang II-mediated inhibition of PPRE-activity which ultimately leads to high concentrations of Ang II in human adipose tissue.

    Peroxisome proliferator activated receptor gamma activity is low in mature primary human visceral adipocytes2007In: Diabetologia, ISSN 0012-186X, E-ISSN 1432-0428, Vol. 50, no 1, 195-201 p.Article in journal (Refereed)
    Abstract [en]

    AIMS/HYPOTHESIS: The amount of visceral fat mass strongly relates to insulin resistance in humans. The transcription factor peroxisome proliferator activated receptor gamma (PPARG) is abundant in adipocytes and regulates genes of importance for insulin sensitivity. Our objective was to study PPARG activity in human visceral and subcutaneous adipocytes and to compare this with the most common model for human disease, the mouse.

    MATERIALS AND METHODS: We transfected primary human adipocytes with a plasmid encoding firefly luciferase controlled by PPARG response element (PPRE) from the acyl-CoA-oxidase gene and measured PPRE activity by emission of light. RESULTS: We found that PPRE activity was 6.6-fold higher (median) in adipocytes from subcutaneous than from omental fat from the same subjects (n = 23). The activity was also 6.2-fold higher in subcutaneous than in intra-abdominal fat cells when we used a PPARG ligand-binding domain-GAL4 fusion protein as reporter, demonstrating that the difference in PPRE activity was due to different levels of activity of the PPARG receptor in the two fat depots. Stimulation with 5 micromol/l rosiglitazone did not induce a PPRE activity in visceral adipocytes that was as high as basal levels in subcutaneous adipocytes. Interestingly, in mice of two different strains the PPRE activity was similar in visceral and subcutaneous fat cells.

    CONCLUSIONS/INTERPRETATION: We found considerably lower PPARG activity in visceral than in subcutaneous primary human adipocytes. Further studies of the molecular mechanisms behind this difference could lead to development of drugs that target the adverse effects of visceral obesity.

    OBJECTIVE: We studied the activity and regulation of the peroxisome proliferator-activated receptor-gamma response element (PPRE) in primary human adipocytes.

    METHODS: We transfected primary human adipocytes with a plasmid-encoding firefly luciferase cDNA under control of a PPRE from the acyl-coenzyme A oxidase gene by using our newly developed electroporation-based method. Several fatty acids were added to the fat cells to study potential activation of peroxisome proliferator-activated receptor-gamma.

    RESULTS: Cells responded maximally to 5 microM of rosiglitazone at a 5.1 +/- 1.4-fold over basal increase in luciferase activity. There was a positive correlation between body mass index and the response to 5 microM of rosiglitazone (r = 0.36, P = 0.03). Patients with type 2 diabetes had similar basal PPRE activity but responded more strongly to 5 microM of rosiglitazone than did non-diabetic subjects (10.2 +/- 5-fold and 5.4 +/- 1-fold over basal increase, respectively, P < 0.0001). Among saturated fatty acids, lauric acid was without effect, but 10 microM of palmitic or stearic acid increased PPRE activity 20% to 35% above basal levels. Monounsaturated palmitoleic acid at 1 microM induced a PPRE transcriptional activity that corresponded to half the therapeutic levels of rosiglitazone.

    CONCLUSION: Adipocytes from obese subjects and patients with type 2 diabetes responded particularly strongly to the effect of rosiglitazone on PPRE. Because fatty acids in the diet can affect the transcriptional activity of peroxisome proliferator-activated receptor-gamma over decades, the stimulation induced by stearic and palmitoleic acids can affect insulin sensitivity and, hence, cardiovascular morbidity and mortality in humans.

    Expression of a mutant IRS inhibits metabolic and mitogenic signalling of insulin in human adipocytes2004In: Molecular and Cellular Endocrinology, ISSN 0303-7207, Vol. 221, no 1-2, 1-8 p.Article in journal (Refereed)
    Abstract [en]

    Adipose tissue is a primary target of insulin, but knowledge about insulin signalling in human adipocytes is limited. We developed an electroporation technique for transfection of primary human adipocytes with a transfection efficiency of 15% ± 5 (mean ± S.D.). Human adipocytes were co-transfected with a mutant of IRS-3 (all four potential PI3-kinase binding motifs mutated: IRS-3F4) and HA-tagged protein kinase B (HA-PKB/Akt). HA-PKB/Akt was immunoprecipitated from cell lysates with anti-HA antibodies, resolved with SDS-PAGE, and immunoblotted with phospho-specific antibodies. We found that IRS-3F4 blocked insulin stimulation of HA-PKB/Akt phosphorylation and in further analyses also translocation of recombinant HA-tagged glucose transporter to the plasma membrane. IRS-3F4 also blocked insulin-induced activation of the transcription factor Elk-1. Our results demonstrate the critical importance of IRS for metabolic as well as mitogenic signalling by insulin. This method for transfection of primary human adipocytes will be useful for studying insulin signalling in human adipocytes with molecular biological techniques.

    Risk factors for lymph node metastases in women with endometrial cancer: A population-based, nation-wide register studyOn behalf of the Swedish Gynecological Cancer Group2017In: International Journal of Cancer, ISSN 0020-7136, E-ISSN 1097-0215, Vol. 140, no 12, 2693-2700 p.Article in journal (Refereed)
    Abstract [en]

    The role of lymphadenectomy in the management of early endometrial cancer remains controversial. In the recent ESMO-ESGO-ESTRO guidelines, lymphadenectomy is recommended for patients with endometrioid adenocarcinoma Grade 3 with deep myometrial invasion, but complete agreement was not achieved. In Sweden, DNA aneuploidy has been included as a high-risk factor. The aim of our study was to evaluate the impact of tumor histology, FIGO grade, DNA ploidy and myometrial invasion (MI) on occurrence of lymph node metastasis (LNM) in patients with endometrial cancer. The study design is a retrospective cohort study based on prospectively recorded register data. Endometrial cancer patients registered in the Swedish Quality Registry for Gynecologic Cancer 2010-2015 with FIGO Stages I-III and verified nodal status were included. Data on DNA ploidy, histology, FIGO grade and MI were included in multivariable log-binomial regression analyses with LNM as dependent variable. 1,165 cases fulfilled the inclusion criteria. The multivariable analyses revealed increased risk of LNM in patients with tumors with MI50% (risk ratio [RR]=4.1; 95% confidence interval [CI] 3.0-5.6), nonendometrioid compared to endometrioid histology (RR 1.8; CI 1.4-2.4) and FIGO Grade 3 compared to Grade 1-2 tumors (RR 1.5; CI 1.1-2.0). No statistically significant association between DNA ploidy status and LNM was detected. This population-based, nation-wide study in women with endometrial cancer confirms a strong association between MI50%, nonendometrioid histology and FIGO Grade 3, respectively, and LNM. DNA ploidy should not be included in the preoperative decision making of removing nodes or not. Whats new? Whether lymphadenectomy is beneficial for women with endometrial cancer remains uncertain. Moreover, additional studies are needed to explore factors that reliably predict lymph node metastasis (LNM). Here, multiple factors, including tumor histology, grade of differentiation and DNA aneuploidy, were evaluated for associations with LNM risk in women with endometrial cancer and verified lymph node status. Most significantly, deep myometrial invasion in tumors increased LNM risk fourfold, whereas DNA ploidy had essentially no impact on LNM risk. The findings confirm the predictive relevance of myometrial invasion, histology and grade reported in previous single-center and multicenter studies.
