  • Ongoing or previous mental disorders predispose to adverse mood reporting during combined oral contraceptive use
  • 2018
  • Ingår i: European Journal of Contraception and Reproductive Health Care. - : TAYLOR & FRANCIS LTD. - 1362-5187 .- 1473-0782. ; 23:1, s. 45-51

    • Purpose: Previous studies have emphasised that women with pre-existing mood disorders are more inclined to discontinue hormonal contraceptive use. However, few studies have examined the effects of combined oral contraceptives (COC) on mood in women with previous or ongoing mental disorders. Materials and methods: This is a supplementary analysis of an investigator-initiated, double-blinded, randomised clinical trial during which 202 women were treated with either a COC (1.5mg estradiol and 2.5mg nomegestrolacetate) or placebo during three treatment cycles. The Mini International Neuropsychiatric Interview was used to collect information on previous or ongoing mental disorders. The primary outcome measure was the total change score in five mood symptoms on the Daily Record of Severity of Problems (DRSP) scale in the intermenstrual phase of the treatment cycle. Results: Women with ongoing or previous mood, anxiety or eating disorders allocated to COC had higher total DRSP -scores during the intermenstrual phase of the treatment cycle in comparison with corresponding women randomised to placebo, mean difference 1.3 (95% CI 0.3-2.3). In contrast, among women without mental health problems, no difference in total DRSP -scores between COC- and placebo users was noted. Women with a risk use of alcohol who were randomised to the COC had higher total DRSP -scores than women randomised to placebo, mean difference 2.1 (CI 95% 1.0-3.2). Conclusions: Women with ongoing or previous mental disorders or risk use of alcohol have greater risk of COC-induced mood symptoms. This may be worth noting during family planning and contraceptive counselling.

  • Combined oral contraceptive use is associated with both improvement and worsening of mood in the different phases of the treatment cycle-A double-blind, placebo-controlled randomized trial
  • 2017
  • Ingår i: Psychoneuroendocrinology. - : PERGAMON-ELSEVIER SCIENCE LTD. - 0306-4530 .- 1873-3360. ; 76, s. 135-143

    • Objective: Ever since the introduction of combined oral contraception (COC), one of the major reasons for discontinuing the pill use has been mood-related side effects. Moreover, women who discontinue the pill turn to less effective methods whereby the probability of an unintended conception increases. Approximately 4-10% of COC users complain of depressed mood, irritability or increased anxiety, but drug-related causality has been difficult to prove. Given the lack of randomized controlled trials in this area, we aimed to prospectively estimate the severity of adverse mood in COC users that would be as representative of general users as possible. Methods: This investigator-initiated, multi-center, randomized, double-blinded, placebo-controlled study included 202 healthy women. Women were randomized to a COC (1.5 mg estradiol and 2.5 mg nomegestrolacetate) or placebo for three treatment cycles. Main outcome measure was the Daily Record of Severity of Problems (DRSP), which was filled out daily during one baseline cycle and the final treatment cycle. Results: Results from 84 women in the COC group and 94 women in the placebo group were analysed. COC use was associated with small, but statistically significant, increases in mean anxiety (0.22; 95% CI: 0.07-0.37, p = 0.003), irritability (0.23; 95% CI: 0.07-0.38, p = 0.012), and mood swings scores (0.15; 95% CI: 0.00-0.31, p = 0.047) during the intermenstrual phase, but a significant premenstrual improvement in depression (-0.33; 95% CI: -0.62 to -0.05, p = 0.049). Secondary analyses showed that women with previous adverse hormonal contraceptive experience reported significantly greater mood worsening in the intermenstrual phase in comparison with healthy women, p <0.05. The proportion of women who reported a clinically relevant mood deterioration did not differ between those allocated to COC (24.1%) or placebo (17.0%), p = 0.262. Conclusion: COC use is associated with small but statistically significant mood side effects in the inter menstrual phase. These findings are driven by a subgroup of women who clearly suffer from COC-related side effects. However, positive mood effects are noted in the premenstrual phase and the proportion of women with clinically relevant mood worsening did not differ between treatment groups. (C) 2016 Elsevier Ltd.

  • Contraceptive use among migrant, second-generation migrant and non-migrant women seeking abortion care : a descriptive cross-sectional study conducted in Sweden
  • 2019
  • Ingår i: BMJ sexual & reproductive health. - : BMJ Publishing Group Ltd. - 2515-1991 .- 2515-2009. ; 45:2, s. 118-126
  • Tidskriftsartikel (refereegranskat)abstract
    • INTRODUCTION: The objective of this study was to compare ever-in life contraception use, use of contraception at current conception, and planned use of contraception after an induced abortion, among three groups of women: migrants, second-generation migrants and non-migrant women, and to compare the types of contraception methods used and intended for future use among the three groups of women.METHODS: The cross-sectional study administered a questionnaire face-to-face to women aged 18 years and older who were seeking abortion care at one of six abortion clinics in Stockholm County from January to April 2015.RESULTS: The analysis included 637 women. Migrants and second-generation migrants were less likely to have used contraception historically, at the time of the current conception, and to plan to use contraception after their induced abortion compared with non-migrant women. Historically, non-migrants had used pills (89%) and withdrawal (24%) while migrants had used the copper intrauterine device (24%) to a higher extent compared to the other two groups of women. Both the migrants (65%) and second-generation migrants (61%) were more likely than the non-migrants (48%) to be planning to use long-acting reversible contraception.CONCLUSIONS: Lower proportions of contraception use were found in migrants and second-generation migrants than in non-migrants. In addition, there were significant differences in the types of contraception methods used historically and intended for future use.

  • Selective insulin-like growth factor-I antagonist inhibits mouse embryo development in a dose-dependent manner
  • 2010
  • Ingår i: Fertility and Sterility. - 0015-0282 .- 1556-5653. ; 93:8, s. 2621-2626
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVE: To study the role of a synthetic insulin-like growth factor-I receptor (IGF-IR) antagonist, picropodophyllin, for mouse preimplantation embryo development in vivo and in vitro. DESIGN: In vitro and in vivo study. SETTING: Hospital-based research unit. ANIMALS: FVB/N mice and mouse embryos. INTERVENTION(S): The effect of picropodophyllin in mouse embryo development in vivo and in vitro, immunohistochemistry, ELISA, polymerase chain reaction. MAIN OUTCOME MEASURE(S): Embryo development, presence of IGF-IR, messenger RNA expression, IGF-I synthesis. RESULT(S): The effect of picropodophyllin on embryo development in vitro and in vivo was not reversible. Mice treated with picropodophyllin 1 to 3 days after mating had a reduced number of blastocysts, 40.5% versus 78.8%, and a higher number of embryos with delayed development, 48.6% versus 11.5%. Insulin-like growth factor-IR protein is present in both phosphorylated and nonphosphorylated form at all stages of embryo development. The relative IGF-IR messenger RNA expression was highest in the oocyte and reduced during development to blastocyst stage. Insulin-like growth factor-I in culture media was reduced after picropodophyllin treatment. CONCLUSION(S): We conclude that IGF-I has an important role in normal mouse embryo development and that its receptor plays an essential role in the embryonic genome activation process.

  • "Who Wants to Go Repeatedly to the Hospital?" : Perceptions and Experiences of Simplified Medical Abortion in Rajasthan, India
  • 2016
  • Ingår i: Global qualitative nursing research. - : SAGE PUBLICATIONS INC. - 2333-3936. ; 3
  • Tidskriftsartikel (refereegranskat)abstract
    • The aim of this study is to explore women's experiences and perceptions of home use of misoprostol and of the self-assessment of the outcome of early medical abortion in a low-resource setting in India. In-depth interviews were conducted with 20 women seeking early medical abortion, who administered misoprostol at home and assessed their own outcome of abortion using a low-sensitivity pregnancy test. With home use of misoprostol, women were able to avoid inconvenience of travel, child care, and housework, and maintain confidentiality. The use of a low-sensitivity pregnancy test alleviated women's anxieties about retained products. Majority said they would prefer medical abortion involving a single visit in future. This study provides nuanced understanding of how women manage a simplified medical abortion in the context of low literacy and limited communication facilities. Service delivery guidelines should be revised to allow women to have medical abortion with fewer visits.

  • Sexual function and combined oral contraceptives : a randomised, placebo-controlled trial
  • 2018
  • Ingår i: Endocrine Connections. - : Bioscientifica. - 2049-3614 .- 2049-3614. ; 7:11, s. 1208-1216

    • Objective: The effect of combined oral contraceptives (COCs) on female sexuality has long been a matter of discussion, but placebo-controlled studies are lacking. Thus, the aim of the present study was to investigate if an oestradiol-containing COC influences sexual function.Design: Investigator-initiated, randomised, double-blinded, placebo-controlled clinical trial where 202 healthy women were randomised to a combined oral contraceptive (1.5 mg oestradiol and 2.5 mg nomegestrol acetate) or placebo for three treatment cycles.Methods: Sexual function at baseline and during the last week of the final treatment cycle was evaluated by the McCoy Female Sexuality Questionnaire. Serum and hair testosterone levels were assessed at the same time points.Results: Compared to placebo, COC use was associated with a small decrease in sexual interest (COC median change score: -2.0; interquartile range (IQR): -5.0 to 0.5 vs placebo: -1.0; IQR: -3.0 to 2.0, P=0.019), which remained following adjustment for change in self-rated depressive symptoms (B= -0.80 +/- 0.30, Wald =7.08, P=0.008). However, the proportion of women who reported a clinically relevant deterioration in sexual interest did not differ between COC or placebo users (COC 18 (22.2%) vs placebo 16 (17.8%), P=0.47). Change in other measured aspects of sexual function as well as total score of sexual function did not differ between the two treatments.Conclusions: This study suggests that use of oestradiol-based COCs is associated with reduced sexual interest. However, the changes are minute, and probably not of clinical relevance.

  • Molecular characterization of PRM-associated endometrial changes, PAEC, following mifepristone treatment
  • 2018
  • Ingår i: Contraception. - : Elsevier. - 0010-7824 .- 1879-0518. ; 98:4, s. 317-322
  • Tidskriftsartikel (refereegranskat)abstract
    • Objective: The progesterone receptor modulator (PRM) mifepristone holds the potential to be developed for regular contraception. However, long-term treatment can cause thickening of the endometrium and PRM-associated endometrial changes (PAEC). The objective of this study was to explore the molecular expression of endometrium displaying PAEC after mifepristone treatment in order to understand the future implications of PAEC and safety of long-term use. Study design: Endometrial biopsies were obtained from premenopausal women following 3 months of continuous mifepristone treatment. The biopsies were evaluated regarding occurrence of PAEC and followed up by a comparative analysis of gene expression in PAEC endometrium (n=7) with endometrium not displaying PAEC (n=4). Methods used included microarray analysis, Ingenuity Pathway Analysis (IPA) and real-time polymerase chain reaction. Results: Three genes relevant within endometrial function were up-regulated with PAEC: THY1 (p=.02), ADAM12 (p=.04) and TN-C (p=.04). The proliferation marker MKi67 was not altered (p=.31). None of the differentially regulated genes were involved in the endometrial cancer-signaling pathway (based on IPA knowledge database). Conclusion: The genes altered in endometrium displaying PAEC after 3 months of mifepristone exposure are mainly involved in the structural architecture of tissue. Implications: PAEC features may be explained by the altered genes and their networks affecting tissue architecture although not involved in endometrial cancer signaling pathways, and thus, treatment with mifepristone at this dosage does not show any adverse effect at endometrial level.

  • Persistent organic pollutants and the size of ovarian reserve in reproductive-aged women
  • 2021
  • Ingår i: Environment International. - : Elsevier. - 0160-4120 .- 1873-6750. ; 155
  • Tidskriftsartikel (refereegranskat)abstract
    • Industrial chemicals such as persistent organic pollutants (POPs) have been associated with reduced fertility in women, including longer time-to-pregnancy (TTP), higher odds for infertility, and earlier reproductive senescence. Fertility is highly dependent on the ovarian reserve, which is composed of a prenatally determined stock of non-growing follicles. The quantity and quality of the follicles decline with age, thereby eventually leading to menopause. In the clinical setting, assessing ovarian reserve directly through the histological analysis of follicular density in ovaries is not practical. Therefore, surrogate markers of ovarian reserve, such as serum anti-Müllerian hormone (AMH) are typically used. Here, we studied associations between chemical exposure and ovarian reserve in a cohort of pregnant women undergoing elective caesarean section (n = 145) in Stockholm, Sweden. Full data (histological, clinical, serum) were available for 50 women. We estimated the size of the reserve both directly by determining the density of follicles in ovarian cortical tissue samples, and indirectly by measuring AMH in associated serum samples. Concentrations of 9 organochlorine pesticides (OCPs), 10 polychlorinated biphenyls (PCBs), 3 polybrominated diphenylethers (PBDEs) and 9 perfluoroalkyl substances (PFAS) were determined in serum, and clinical data were retrieved from electronic medical records. Healthy follicle densities (median 0, range 0–193 follicles/mm3) and AMH levels (median 2.33 ng/mL, range 0.1–14.8 ng/mL) varied substantially. AMH correlated with the density of growing follicles. Twenty-three chemicals detected in more than half of the samples were included in the analyses. None of the chemicals, alone or as a mixture, correlated with AMH, growing or atretic follicles. However, HCB, transnonachlor, PCBs 74 and 99 were associated with decreased non-growing follicle densities. HCB and transnonachlor were also negatively associated with healthy follicle density. Further, mixture of lipophilic POPs (PBDE 99, p,p’-DDE, and PCB 187) was associated with lower non-growing follicle densities. In addition, exposure to HCB, p,p’-DDE, and mixture of OCPs were significantly associated with higher odds of infertility. The results suggest that exposure to chemicals may reduce the size of ovarian reserve in humans, and strongly encourage to study mechanisms behind POP-associated infertility in women in more detail.

  • Increasing uptake of long-acting reversible contraception with structured contraceptive counselling : cluster randomised controlled trial (the LOWE trial).
  • 2021
  • Ingår i: British Journal of Obstetrics and Gynecology. - 1470-0328 .- 1471-0528. ; 128:9, s. 1546-1554
  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVES: To evaluate the effect of structured contraceptive counselling on uptake of long-acting reversible contraceptives (LARCs), and pregnancy rates.DESIGN: Cluster randomised trial SETTING: Abortion, youth, and maternal health clinics in Stockholm, Sweden.POPULATION: Sexually active women ≥18 years without a wish for pregnancy seeking abortion and/or contraceptive counselling.METHODS: For participants in clinics randomised to intervention, trained health care providers implemented a study-specific intervention package designed for structured contraceptive counselling. Participants in the control clinics received routine counselling.MAIN OUTCOME MEASURES: Primary outcome was choice of LARCs at first visit. Secondary outcomes were LARC initiation at three months and pregnancy rates at three and 12 months. We used logistic mixed-effects models with random intercept for clinic to account for clustering.RESULTS: From September 2017 to May 2019, 28 randomised clinics enrolled 1364 participants. Analyses including 1338 subjects showed that more participants in the intervention compared to control group chose LARCs (267/658 (40.6%) versus 206/680 (30.3%), odds ratio (OR) 2.77, 95% CI 1.99 to 3.86). LARC initiation was higher in the intervention compared to the control group (213/528 (40.3%) versus 153/531 (28.8%), OR 1.74, 95% CI 1.22 to 2.49). At abortion clinics, pregnancy rate was significantly lower at 12 months in the intervention versus the control group (13/101 (12.9%) versus 28/103 (27.2%), OR 0.39, 95% CI 0.18 to 0.88).CONCLUSIONS: Structured contraceptive counselling increased LARC uptake in all clinics and significantly reduced unintended pregnancy rates in abortion clinics at 12 months follow-up.
