- Introduction: Complications after gynecological surgery in Sweden are registered in the well-established Swedish National Quality Register of Gynecological Surgery, GynOp. The aim of this study was to analyze interrater reliability in assessing complications according to the methods in GynOp, and to explore physicians' perceptions of registering complications.Material and methods: A digital survey was sent to gynecologists and residents in gynecology in Sweden. Participating clinics were recruited through the Swedish network for national clinical studies in Obstetrics and Gynecology, SNAKS. Twenty fictional cases, intended to represent normal postoperative course, failure to cure, and varying degrees of complications, were developed by the research group. The clinical scenarios included abdominal and laparoscopic surgery of the uterus and adnexa, vaginal hysterectomies, as well as hysteroscopy. The respondents graded each case on the presence of a complication (yes/no). Type of complication, severity, and what action the complication required according to Clavien-Dindo was registered if a complication was acknowledged, according to the method in GynOp. Interrater reliability and the opinions of the respondents were presented descriptively. More than 80% of respondents making the same assessment was considered as agreement.Results: The response rate was 41%, with 104 responding physicians from 16 gynecological clinics. Type and severity of complication was considered relevant to register by 88% and 89% of respondents, respectively. Agreement on whether the case described a complication was >80% in 85% (17/20) of cases and agreement using the Clavien-Dindo classification was >90% in 80% (16/20) of cases. There was high agreement in assessments of classically severe complications, such as pulmonary embolism and ureteral damage, in both presence of complication and severity, as well as Clavien-Dindo (>90% for all methods). Cases with agreement <80% on whether the case described a complication were bordering between normal postoperative course and minor complication.Conclusions: This study provides validation for the methods used to register complications after gynecological surgery according to the GynOp register, including the use of Clavien-Dindo in gynecology. However, the results indicate a need to define what should be considered symptoms inherent to each type of surgery.

HOPPSA update: changes in the study protocol of Hysterectomy and OPPortunistic SAlpingectomy, a registry-based randomized controlled trial
- 2023

Tidskriftsartikel (refereegranskat)abstract
- Background The HOPPSA trial is a multi-center national registry-based randomized controlled trial to test the safety and effectiveness of performing opportunistic salpingectomy at hysterectomy to reduce the risk of epithelial ovarian cancer (EOC). The study protocol was first published in January 2019 and is available at . Here, we report amendments made to the study protocol since commencement of the trial.Changes in methods and analysis The primary outcomes analyses have been changed. (1) Complications will be analyzed using binomial generalized estimating equation (GEE) with log link function, while the unadjusted analyses according to Miettinen and Nurminen will be performed as a sensitivity analysis. (2) Absolute change in Menopause Rating Scale (MRS) will primarily be analyzed using a mixed effects model, adjusted for baseline MRS and center as a random effect. (3) Time to EOC will be analyzed using the mixed effects Cox regression model with center as random effect, while the unadjusted log-rank test will be performed as a sensitivity analysis.The primary outcome Complications will be based solely on the specific assessment in the GynOp quality registry. The Clavien-Dindo classification will be evaluated as a secondary outcome.Furthermore, MRS is also measured three years postoperatively to better pinpoint the onset of menopausal symptoms.Discussion The changes to the protocol mainly concern the analyses of data. No changes to recruitment, randomization, intervention, or follow-up of primary outcomes have been made. An interim analysis during 2021 concluded that the study should continue until the target sample size is reached.

Forskningsöversikt (refereegranskat)abstract
- Purpose: The objective of this systematic review is to evaluate current literature comparing salpingectomy for sterilisation with tubal ligation, regarding the effectiveness and safety, and assess the certainty of evidence. Materials and methods: PubMed, Cochrane, and Embase databases were searched. Randomised (RCT) and observational studies were included. Articles were quality assessed and data extracted by two independent authors. Certainty of evidence was assessed using GRADE. Results: Of 2020 articles, 17 were included. No study investigated the risk of EOC. No difference in anti-Müllerian hormone was reported in one RCT at caesarean section (CS). Two cohort studies evaluated ovarian function with surrogate measures and found no difference at caesarean section. Complications did not differ but were inconsistently reported. Laparoscopic tubal ligation was 7 min faster (95% CI 3.8–10.5). Operative time at caesarean section was dependent on the use of surgical devices. Certainty of evidence was low or very low for all estimates, indicating knowledge gaps. Reliable safety data on salpingectomy for sterilisation is lacking, and there is no effectiveness data. Presently, women cannot be properly counselled regarding salpingectomy for sterilisation.

Tidskriftsartikel (refereegranskat)abstract
- Salpingectomy is currently suggested as an alternative to tubal ligation for sterilisation. Precursor lesions of ovarian carcinoma can be found in the fallopian tubes; thus, salpingectomy could possibly reduce the incidence. Most of the existing trials on safety are small, on caesarean section and report on surrogate ovarian function measures. Randomised trials in laparoscopy are lacking. Well-designed trials are needed to evaluate safety of laparoscopic opportunistic salpingectomy.In SALSTER, a national register-based randomised controlled non-inferiority trial, 968women <50 years, wishing laparoscopic sterilisation will be randomised to either salpingectomy or tubal ligation. The Swedish National Quality Register of Gynecological Surgery (GynOp) will be used for inclusion, randomisation and follow-up. Primary outcomes are any complication up to 8weeks postoperatively, and age at menopause. Both outcomes are measured with questionnaires, complications are also assessed by a gynaecologist. In a nested trial, ovarian function will be evaluated comparing the mean difference of anti-Müllerian hormone (AMH), assessed preoperatively and 1year after surgery.Performing salpingectomy for sterilisation has become increasingly common, despite the unclear risk-benefit balance. SALSTER studies the safety of salpingectomy compared with tubal ligation. Regardless of the result, SALSTER will provide gynaecologists with high quality evidence to inform women to decide on salpingectomy or not. The central ethical review board of Gothenburg, Sweden (Dnr. 316-18) approved the trial in 2018. Results will be presented at scientific congresses and published in peer-reviewed scientific journals. The results will be communicated through professional organisations and research networks.NCT03860805.

Tidskriftsartikel (refereegranskat)abstract
- In this post hoc study, arachidonic acid (AA)-induced platelet aggregation during pregnancy with and without acetylsalicylic acid (ASA) treatment was studied in 323 women with unexplained recurrent first-trimester miscarriage and in 59 healthy women with normal pregnancies. All women had normal AA-induced platelet aggregation in the non-pregnant state. Women with recurrent miscarriage were treated with 75 mg ASA or placebo daily. AA-induced platelet aggregation was measured with multiple electrode impedance aggregometry and presented in units (U), where 1 U = 10 aggregation units x minutes. There were no significant differences in platelet aggregation between placebo-treated women with recurrent miscarriage and healthy women. The mean differences were -0.7 (95%CI; -7.0; 5.6) U in the non-pregnant state, 3.8 (95%CI; -4.6; 12.2) U during the late first trimester and 1.7 (95%CI; -6.7; 10.3) U and 4.1 (95%CI; -3.9; 12.0) U during the early and late third trimester, respectively. ASA reduced platelet aggregation by median -84.0% (Q1; Q3; -89.8; -76.3), -79.9% (-84.7; -69.2) and -75.7% (-83.5; -49.5), respectively, during pregnancy. The degree of inhibition by ASA decreased during the third trimester (p < .0001). There were two (1.9%) complete non-responders to ASA and 32.1% with a partial response. The rate of subsequent miscarriage was not affected by ASA, which did not seem to influence the rate of early miscarriage if treatment was initiated when a viable pregnancy was detectable by ultrasound.

- To investigate preconceptual thyroid peroxidase antibody (TPO-ab) positivity and/or thyroid stimulating hormone (TSH) levels in the upper range of normal as risk factors for recurrent unexplained first-trimester miscarriage.A post-hoc study of a randomized trial, in which acetylsalicylic acid did not affect the risk of a new miscarriage.Women (n=483) with at least three unexplained recurrent first-trimester miscarriages investigated at a Swedish secondary referral center.The levels of TPO-ab and TSH were determined before pregnancy. The occurrence of a new first-trimester miscarriage was analyzed by logistic regression with adjustments when applicable, for age, number of previous miscarriages, obesity and the investigated covariates levels of TPO-ab and TSH.Including all first trimester miscarriages, odds ratio (OR) according to presence of TPO-ab was 1.60 (95% confidence interval [CI]; 0.99-2.57), after adjustment 1.54 (95% CI; 0.94-2.53). Very early (biochemical) pregnancy losses occurred more often in women with than without preconceptual TPO-ab (6.8% vs. 2.0%), OR 3.51 (95% CI; 1.15-10.71), after adjustment 2.91 (95% CI; 0.91-9.29). There was no association between TSH in the upper range of normal and a new miscarriage, adjusted OR 0.76 (95% CI; 0.32-1.83). A prediction model for a new miscarriage included number of previous miscarriages, woman's age and presence of TPO-ab.In women with at least three recurrent unexplained pregnancy losses, the presence of TPO-ab may contribute to an increased risk of a first-trimester miscarriage, possibly more pronounced in very early pregnancy. TSH levels 2.5-4.0 mU/L do not seem to increase the miscarriage risk.

Tidskriftsartikel (refereegranskat)abstract
- Objective: To address methodological deficiencies in published randomized controlled trials and systematic reviews, this study has developed a core outcome set to guide future research in ectopic pregnancy (EP).Design: To identify potential outcomes, we performed a comprehensive literature review and interviews with individuals with lived experience in EP. Potential core outcomes were then entered into a 3-round Delphi survey. A total of 154 participants from 6 continents, comprising health care professionals, researchers, and individuals with lived experience in EP, completed all 3 rounds of the Delphi survey. Outcomes were prioritized at 3 consensus development meetings, and recommendations were developed on how to report these outcomes where possible.Setting: Not applicable.Patient(s): Health care professionals, researchers, and individuals with lived experience in EP.Intervention(s): Not applicable.Main Outcome Measure(s): Consensus for inclusion in core outcome set.Result(s): Six outcomes reached full consensus, including treatment success, resolution time, the number of additional interventions, adverse events, mortality and severe morbidity, and treatment satisfaction.Conclusion(s): The core outcome set with 6 outcomes for EP will help standardize reporting of clinical trials, facilitate implementation of findings into clinical practice, and enhance patient-centered care.

Ingår i: Trials. - : Springer Science and Business Media LLC. - 1745-6215. ; 22:1
-
Tidskriftsartikel (refereegranskat)abstract
- Background: Randomised controlled trials (RCTs) evaluating ectopic pregnancy have reported many different outcomes, which are themselves often defined and measured in distinct ways. This level of variation results in an inability to compare results of individual RCTs. The development of a core outcome set to ensure outcomes important to key stakeholders are collected consistently will guide future research in ectopic pregnancy. Study aim: To develop and implement a core outcome set to guide future research in ectopic pregnancy. Methods and analysis: We have established an international steering group of key stakeholders, including healthcare professionals, researchers, and individuals with lived experience of ectopic pregnancy. We will identify potential outcomes from ectopic pregnancy from a comprehensive literature review of published randomised controlled trials. We will then utilise a modified Delphi method to prioritise outcomes. Subsequently, key stakeholders will be invited to score potential core outcomes on a nine-point Likert scale, ranging from 1 (not important) to 9 (critical). Repeated reflection and rescoring should promote whole and individual stakeholder group convergence towards consensus 'core' outcomes. We will also establish standardised definitions and recommend high-quality measurements for individual core outcomes.

- STUDY QUESTION: What is the rate of natural conception leading to ongoing pregnancy or livebirth over 6-12 months for infertile women of age >= 35 years? SUMMARY ANSWER: Natural conception rates were still clinically relevant in women aged 35 years and above and were significantly higher in women with unexplained infertility compared to those with other diagnoses. WHAT IS KNOWN ALREADY: In recent years, increasing numbers of women have attempted to conceive at a later age, resulting in a commensurate increase in the need for ART. However, there is a lack of data on natural fertility outcomes (i.e. no interventions) in women with increasing age. STUDY DESIGN, SIZE, DURATION: A systematic review with individual participant data (IPD) meta-analysis was carried out. PubMed, MEDLINE, EMBASE, the Cochrane Library, clinicaltrials.gov were searched until 1 July 2018 including search terms 'fertility service', 'waiting list', 'treatment-independent' and 'spontaneous conception'. Language restrictions were not imposed. PARTICIPANTS/MATERIALS, SETTING, METHODS: Inclusion criteria were studies (at least partly) reporting on infertile couples with female partner of age >= 35 years who attended fertility services, underwent fertility workup (e.g. history, semen analysis, tubal status and ovulation status) and were exposed to natural conception (e.g. independent of treatment such as IVF, ovulation induction and tubal surgery). Studies that exclusively studied only one infertility diagnosis, without including other women presenting to infertility services for other causes of infertility, were excluded. For studies that met the inclusion criteria, study authors were contacted to provide IPD, after which fertility outcomes for women of age >= 35 years were retrieved. Time to pregnancy or livebirth and the effect of increasing age on fertility outcomes after adjustment for other prognostic factors were analysed. Quality of studies was graded with the Newcastle-Ottawa Scale (non-randomised controlled trials (RCTs)) or the Cochrane Risk of Bias tool (for RCTs). MAIN RESULTS AND THE ROLE OF CHANCE: We included nine studies (seven cohort studies and two RCTs) (n = 4379 women of at least age 35 years), with the observed composite primary outcome of ongoing pregnancy or livebirth occurring in 429 women (9.8%) over a median follow-up of 5 months (25th to 75th percentile: 2.5-8.5 months). Studies were of moderate to high quality. The probability of natural conception significantly decreased with any diagnosis of infertility, when compared with unexplained infertility. We found non-linear effects of female age and duration of infertility on ongoing pregnancy and tabulated the predicted probabilities for unexplained infertile women aged 35-42 years with either primary or secondary infertility and with a duration of infertility from 1 to 6 years. For a 35-year-old woman with 2 years of primary unexplained infertility, the predicted probability of natural conception leading to ongoing pregnancy or livebirth was 0.15 (95% CI 0.11-0.19) after 6 months and 0.24 (95% CI 0.17-0.30) after 12 months. For a 42-year-old woman, this decreased to 0.08 (95% CI 0.04-0.11) after 6 months and 0.13 (95% CI 0.07-0.18) after 12 months. LIMITATIONS, REASONS FOR CAUTION: In the studies selected, there were different study designs, recruitment strategies in different centres, protocols and countries and different methods of assessment of infertility. Data were limited for women above the age of 40 years. WIDER IMPLICATIONS OF THE FINDINGS: Women attending fertility services should be encouraged to pursue natural conception while waiting for treatment to commence and after treatment if it is unsuccessful. Our results may aid in counselling women, and, in particular, for those with unexplained infertility.
