- BACKGROUND: In recent years, the fallopian tubes have been found to play a critical role in the pathogenesis of ovarian cancer. Therefore, bilateral salpingectomy at the time of hysterectomy has been proposed as a preventive procedure, but with scarce scientific evidence to support the efficiency and safety. OBJECTIVE: Our primary objective was to evaluate the risk of surgical complications and menopausal symptoms when performing bilateral salpingectomy in addition to benign hysterectomy. Furthermore, we sought to compare time in surgery, perioperative blood loss/blood transfusion, duration of hospital stay, days to normal activities of daily living, and days out of work for hysterectomy with bilateral salpingectomy compared with hysterectomy only. A secondary objective was to study the uptake of opportunistic salpingectomy in Sweden. STUDY DESIGN: This was a retrospective observational cohort study based on data from the National Quality Register of Gynecological Surgery in Sweden. Women <55 years of age who had a hysterectomy for benign indications with or without bilateral salpingectomy in 1998 through 2016 were included. Possible confounding was adjusted for in multivariable regression models. RESULTS: During the study period, 23,369 women had a hysterectomy for benign indications. The frequency of bilateral salpingectomy at the time of hysterectomy increased mainly from 2013, which is why the period 2013 through mid-2016 was selected for further analysis (n = 6892). There was a low frequency of vaginal hysterectomy with bilateral salpingectomy performed in this period, which is why only abdominal and laparoscopic surgeries were selected for comparative analysis (n = 4906). This study indicates an increased risk of menopausal symptoms (adjusted relative risk, 1.33; 95% confidence interval, 1.04-1.69) 1 year after hysterectomy with bilateral salpingectomy compared with hysterectomy only. Hospital stay was 0.1 days longer in women having salpingectomy (P = .01), and bleeding was slightly reduced in the salpingectomy group (-20 mL, P = .04). Other outcome measures were not significantly associated with salpingectomy, albeit a tendency toward higher risk of minor complications was seen (adjusted relative risk, 1.30; 95% confidence interval, 0.93-1.83). CONCLUSION: Bilateral salpingectomy at the time of hysterectomy was associated with an increased risk of menopausal symptoms 1 year after surgery. Randomized clinical trials reducing the risk of residual and unmeasured confounding and longer follow-up are needed to correctly inform women on the risks and benefits of opportunistic salpingectomy.

Physicians' assessment of complications after gynecological surgery in Sweden : The GYNCOM survey
- 2023

- 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.

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.

Hysterectomy and opportunistic salpingectomy (HOPPSA): study protocol for a register-based randomized controlled trial

- BackgroundThere is a great need for a prospective randomized trial to evaluate the risks and benefits of opportunistic salpingectomy. Recently, genetic and morphologic studies have indicated that epithelial ovarian cancer predominantly develops in the Fallopian tubes. Consequently, there is reason to believe that salpingectomy would reduce the risk of ovarian cancer. Studies on reducing the risk of ovarian cancer have compared indicated salpingectomy with no salpingectomy, while studies on surgical safety as well as ovarian function after opportunistic salpingectomy have been small with a short follow-up. No study has reported menopausal symptoms.Methods/designIn this national register-based randomized controlled trial, women <55years old, planned for a hysterectomy for a benign cause, will be randomized to concomitant salpingectomy or no salpingectomy. The follow-up will be conducted according to already established routines within the register using on-line questionnaires. Primary outcomes have been defined for three different time points: short-term complications up to 8 weeks postoperatively (n=2800), intermediate-term changes in menopausal symptoms measured by the Menopause Rating Scale at baseline and after 1 year (n=1670), and long-term epithelial ovarian cancer assessed through national registers after 30years (n=5052) (or n=7001 for high-grade serous cancer). In a sub-study of 75 women, ovarian function will be evaluated through change in anti-Mullerian hormone measured before surgery and after 1 year.DiscussionHysterectomy for a benign cause is a common surgical procedure and several national societies recommend salpingectomy while performing a benign hysterectomy, despite a lack of scientific evidence for the safety of the procedure. Sweden has unique conditions for clinical trials because of its national quality registers and health registers with excellent quality and near complete coverage. If no additional risks are associated with concomitant salpingectomy, it can be recommended at the time of benign hysterectomy to reduce the risk of epithelial ovarian cancer. If not, the risks and benefits must be balanced. The results of this study will be important for informing women undergoing a benign hysterectomy.Trial registrationClinicalTrials.gov, NCT03045965.

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.

Forskningsöversikt (refereegranskat)abstract
- To improve the accuracy of chemoradiation therapy in anal cancer patients PET/CT is frequently used in the planning of radiation therapy. A systematic review was performed to assess impact on survival, quality of life, symptom score, change in target definition and treatment intention. Systematic literature searches were conducted in Medline, EMBASE, the Cochrane Library, and Centre for Reviews and Dissemination. Ten cross-sectional studies were identified. No data were available on survival or quality of life. The summary estimate of the proportion of patients in which PET/CT had an impact on the target definition, was 23% (95% CI 16;33). The corresponding summary estimate of a change in treatment intent from curative to palliative was 3% (95% CI 2;6). Almost one in four patients had a change in target definition, which supports the use of PET/CT in radiation therapy planning, but the consequence regarding survival and quality of life is still uncertain.

- HTA (health technology assessment) innebär en systematisk granskning av det vetenskapliga underlaget för en viss teknik. Ett väl definierat PICO (patients, intervention, comparison, outcome) är en grundförutsättning för att få fram den dokumentation som ska granskas. En fokuserad fråga är central i HTA-processen. En teknik granskas med avseende på effektivitet och risker, etiska och organisatoriska aspekter samt kostnader. I en systematisk litteraturöversikt granskas vetenskapliga artiklar med avseende på kvalitet och relevans. Slutsatserna evidensgraderas enligt GRADE. I Västra Götalandsregionen har inrättats ett HTA-centrum som arbetar med regional medicinsk utvärdering. Regionalt HTA-arbete har flera fördelar; en är att den praktiska omsättningen av de nyvunna kunskaperna troligen kan ske snabbare.

Platelet aggregation in healthy women during normal pregnancy - a longitudinal study.
- 2019

Tidskriftsartikel (refereegranskat)abstract
- Increased platelet activation is involved in obstetric complications such as preeclampsia and intrauterine growth retardation. It is of interest to study platelet aggregation during pregnancy, since increased aggregation theoretically could be a mechanism associated with placenta-mediated complications, which possibly could be prevented by drugs inhibiting platelet aggregation. There are, however, few robust studies describing platelet aggregation during normal pregnancy. The present longitudinal study was performed in order to study platelet aggregation during normal pregnancy resulting in a healthy child, during the puerperium and in nonpregnant, fertile women. Healthy, nonsmoking, pregnant women (n=104), aged under 39years and with BMI <35, were followed during pregnancy and postpartum. Twenty-seven nonpregnant, non-puerperal, fertile women were studied for comparison. Platelet aggregation was determined with multiple electrode impedance aggregometry and analyzed at inclusion, 4 times during pregnancy and after at least 3 months postpartum. Platelet aggregation postpartum was compared with gestational weeks 8-15 and 37-40, respectively, and with nonpregnant, fertile women. Hemoglobin, leucocyte count, platelet count, prothrombin time, and activated partial thromboplastin time were determined at inclusion in order to verify normal hemostasis. Activation of platelets by arachidonic acid, adenosine diphosphate (ADP), and thrombin receptor activating peptide (trap-6) resulted in less aggregation during pregnancy, compared with postpartum (p<0.03-<0.001). Platelet aggregation following activation by collagen was unchanged. A minor increase in aggregation as pregnancy continued was found related to ADP (p<0.021). Positive correlations were found between platelet counts and platelet aggregation. Postpartum platelet aggregation after activation with arachidonic acid, collagen, and trap-6 was lower than in the non-puerperal fertile state. Other hemostatic analyses were normal. In conclusion, there is a minor decrease in platelet aggregation after activation with arachidonic acid, trap-6, and ADP, measured with multiple electrode impedance aggregometry during normal pregnancy resulting in healthy babies, compared with the postpartum period. The small changes in platelet aggregation may be a consequence of a minor decrease in platelet count and probably lack clinical significance under normal conditions. Interindividual variations at certain time-points are substantial, which limits the usefulness of the multiple electrode impedance aggregometry for determining minor changes in platelet function.

Tidskriftsartikel (refereegranskat)abstract
- Introduction: Recurrent pregnancy loss occurs in about 1% of fertile couples. Without proper evidence for an effect, different treatments have been used when no etiological factor has been detected. The present trial is the first randomized trial to compare 75 mg acetylsalicylic acid with placebo for women with recurrent pregnancy loss. Material and methods: This randomized, double-blind, placebo-controlled trial was conducted at a single center between 2008 and 2015. Recurrent pregnancy loss was defined as at least 3 consecutive first-trimester miscarriages within the couple. Women < 40 years old with a body mass index < 35 kg/m(2) were eligible if the workup was negative. Randomization was through a third party, who manufactured and delivered the study drugs, and occurred when fetal heartbeat was detected, to either 75 mg acetylsalicylic acid or placebo; 200 women in each group. Group allocation was concealed until all the study participants had a pregnancy outcome registered. All women attended the same control program. Primary outcome was live birth. Statistical analyses were according to intention-to-treat. Results: All 400 women completed the follow up. Live birth rate was 83.0% (n=166) and 85.5% (n=171) for the acetylsalicylic acid and placebo groups, respectively (P=0.58). The difference was -2.5% (95% CI -10.1% to 5.1%). The risk ratio was 0.97 (95% CI 0.89-1.06). Conclusions: Treatment with acetylsalicylic acid did not prevent recurrent miscarriage in women with at least three consecutive miscarriages in the first trimester, of unknown reasons and in the same relationship. The fertility prognosis is very good, the live birth rate being > 80% with or without acetylsalicylic acid.

- 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
- Introduction and hypothesis: Innovations in suturing devices have facilitated sacrospinous ligament fixation (SSF) for the correction of vaginal vault prolapse. It is uncertain if outcomes using suturing devices differ from those using a traditional suturing technique. We hypothesize that no difference exists in the efficacy and safety 1 year after SSF for vault prolapse performed with suturing devices or using a traditional technique. The objective was to compare SSF using a suturing device with traditional SSF for the treatment of vault prolapse, regarding symptoms of prolapse recurrence, patient satisfaction, incidence of re-operation, and complications 1 year postoperatively.Methods: We carried out a retrospective cohort study using register-based national data from 2006 to 2013. The Swedish Quality Register of Gynecological Surgery includes assessments pre-operatively, at hospital admittance, surgery, discharge, and questionnaires at 8 weeks and 1 year after surgery. Demographic variables and surgical methods were included in multivariate logistic regression analyses.Results: In the suturing device group (SDG, n = 353), 71.5% were asymptomatic of recurrence after 1 year compared with 78.7% in the traditional SSF group (TSG, n = 195); risk difference - 7.3% (95%CI -15.2%; 0.7%). Adjusted odds ratio (aOR) for being asymptomatic 1 year postoperatively was 0.56 (95%CI 0.31; 1.02, p = 0.057). Patient satisfaction was similar in SDG and TSG (78.1% vs 78.4%). Reoperation occurred in 7.4% in the SDG compared with 3.6% in the TSG, risk difference 3.8% (95%CI 0.0%; 7.5%), aOR 3.55 (95%CI 1.10; 11.44, p = 0.03).Conclusions: Patient satisfaction was similar 1 year after SSF, despite symptoms of recurrence being more likely and reoperation more common after using a suturing device compared with a traditional technique. The methods did not differ with regard to surgical complications.

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.

- It has been argued that salpingectomy would reduce the risk of epithelial ovarian cancer (EOC), based on the theory of the tube being the site of origin.To conduct a systematic review of 'salpingectomy' associated with ovarian cancer risk and 'salpingectomy with concomitant hysterectomy' on outcomes of complications including endocrine function.A comprehensive search was conducted in PubMed, Embase, and the Cochrane library.Original studies and systematic reviews were eligible.Each article was quality assessed. Data were extracted and, when possible, pooled in meta-analyses. The certainty of evidence across studies was evaluated using GRADE.Of 844 articles found, 11 were included. No study evaluated risk reduction for EOC after salpingectomy in conjunction with hysterectomy. Two retrospective studies reported a reduced ovarian cancer risk after indicated salpingectomy, compared with no surgery: adjusted hazard ratio 0.65 (95% confidence interval, 95% CI 0.52-0.81) and adjusted odds ratio 0.58 (95% CI 0.36-0.95). Complications did not differ between groups with or without salpingectomy, but were non-systematically reported. Ovarian endocrine function, measured with surrogate outcomes, did not differ at short-term follow-up in randomised or observational studies. The certainty of evidence was very low or low for all outcomes.There is currently insufficient evidence to state that opportunistic salpingectomy reduces the risk of EOC. The impact on long-term endocrine function is unknown. The heterogeneity in results and identified knowledge gaps stress the need for a prospective trial.Insufficient evidence for prophylactic removal of the fallopian tubes for risk reduction of ovarian cancer.

- The proposed different origins and pathways to of the dualistic model of epithelial ovarian cancer (EOC) may affect and alter the potential risk reduction related to hysterectomy, salpingectomy and tubal ligation. The aim of our study was to analyze associations between hysterectomy, salpingectomy or tubal ligation and risk reduction of EOC Type I and II. In this nationwide register-based case-control study, women diagnosed with EOC, Fallopian tube or primary peritoneal cancer between 2008 and 2014 were included. Cases were classified into Type I and II according to histology and predefined criteria. The exposure variables: hysterectomy, salpingectomy and tubal ligation were identified from national registries. Conditional logistic regression analyses were performed to evaluate associations between Type I and II EOC and the exposure variables. Among 4669 registered cases, 4040 were eligible and assessed for subtyping resulting in 1033 Type I and 3007 Type II. Ten controls were randomly assigned to each case from the register of population. In regression analyses, women with previous salpingectomy had a significantly lower risk of EOC Type II (odds ratio [OR] 0.62; 95% confidence interval [95%CI] 0.45-0.85) but not Type I (OR 1.16; 95%CI 0.75-1.78). Hysterectomy was associated with a reduced risk of both EOC Type I (OR 0.71; 95%CI 0.52-0.99) and Type II (OR 0.81; 95%CI 0.68-0.96). Similar estimates were obtained for tubal ligation, although without statistical significance. The association between salpingectomy and reduced risk of EOC Type II supports the proposed theory of high-grade serous cancer originating from the tubal fimbriae.

- STUDY QUESTION: Can a core outcome set to standardize outcome selection, collection and reporting across future infertility research be developed? SUMMARY ANSWER: A minimum data set, known as a core outcome set, has been developed for randomized controlled trials (RCTs) and systematic reviews evaluating potential treatments for infertility. WHAT IS KNOWN ALREADY: Complex issues, including a failure to consider the perspectives of people with fertility problems when selecting outcomes, variations in outcome definitions and the selective reporting of outcomes on the basis of statistical analysis, make the results of infertility research difficult to interpret. STUDY DESIGN, SIZE, DURATION: A three-round Delphi survey (372 participants from 41 countries) and consensus development workshop (30 participants from 27 countries). PARTICIPANTS/MATERIALS, SETTING, METHODS: Healthcare professionals, researchers and people with fertility problems were brought together in an open and transparent process using formal consensus science methods. MAIN RESULTS AND THE ROLE OF CHANCE: The core outcome set consists of: viable intrauterine pregnancy confirmed by ultrasound (accounting for singleton, twin and higher multiple pregnancy); pregnancy loss (accounting for ectopic pregnancy, miscarriage, stillbirth and termination of pregnancy); live birth; gestational age at delivery; birthweight; neonatal mortality; and major congenital anomaly. Time to pregnancy leading to live birth should be reported when applicable. LIMITATIONS, REASONS FOR CAUTION: We used consensus development methods which have inherent limitations, including the representativeness of the participant sample, Delphi survey attrition and an arbitrary consensus threshold. WIDER IMPLICATIONS OF THE FINDINGS: Embedding the core outcome set within RCTs and systematic reviews should ensure the comprehensive selection, collection and reporting of core outcomes. Research funding bodies, the Standard Protocol Items: Recommendations for Interventional Trials (SPIRIT) statement, and over 80 specialty journals, including the Cochrane Gynaecology and Fertility Group, Fertility and Sterility and Human Reproduction, have committed to implementing this core outcome set.

- STUDY QUESTION: Can consensus definitions for the core outcome set for infertility be identified in order to recommend a standardized approach to reporting? SUMMARY ANSWER: Consensus definitions for individual core outcomes, contextual statements and a standardized reporting table have been developed. WHAT IS KNOWN ALREADY: Different definitions exist for individual core outcomes for infertility. This variation increases the opportunities for researchers to engage with selective outcome reporting, which undermines secondary research and compromises clinical practice guideline development. STUDY DESIGN, SIZE, DURATION: Potential definitions were identified by a systematic review of definition development initiatives and clinical practice guidelines and by reviewing Cochrane Gynaecology and Fertility Group guidelines. These definitions were discussed in a face-to-face consensus development meeting, which agreed consensus definitions. A standardized approach to reporting was also developed as part of the process. PARTICIPANTS/MATERIALS, SETTING, METHODS: Healthcare professionals, researchers and people with fertility problems were brought together in an open and transparent process using formal consensus development methods. MAIN RESULTS AND THE ROLE OF CHANCE: Forty-four potential definitions were inventoried across four definition development initiatives, including the Harbin Consensus Conference Workshop Group and International Committee for Monitoring Assisted Reproductive Technologies, 12 clinical practice guidelines and Cochrane Gynaecology and Fertility Group guidelines. Twenty-seven participants, from 11 countries, contributed to the consensus development meeting. Consensus definitions were successfully developed for all core outcomes. Specific recommendations were made to improve reporting. LIMITATIONS, REASONS FOR CAUTION: We used consensus development methods, which have inherent limitations. There was limited representation from low- and middle-income countries. WIDER IMPLICATIONS OF THE FINDINGS: A minimum data set should assist researchers in populating protocols, case report forms and other data collection tools. The generic reporting table should provide clear guidance to researchers and improve the reporting of their results within journal publications and conference presentations. Research funding bodies, the Standard Protocol Items: Recommendations for Interventional Trials statement, and over 80 specialty journals have committed to implementing this core outcome set.

- STUDY QUESTION: Can the priorities for future research in infertility be identified? SUMMARY ANSWER: The top 10 research priorities for the four areas of male infertility, female and unexplained infertility, medically assisted reproduction and ethics, access and organization of care for people with fertility problems were identified. WHAT IS KNOWN ALREADY: Many fundamental questions regarding the prevention, management and consequences of infertility remain unanswered. This is a barrier to improving the care received by those people with fertility problems. STUDY DESIGN, SIZE, DURATION: Potential research questions were collated from an initial international survey, a systematic review of clinical practice guidelines and Cochrane systematic reviews. A rationalized list of confirmed research uncertainties was prioritized in an interim international survey. Prioritized research uncertainties were discussed during a consensus development meeting. Using a formal consensus development method, the modified nominal group technique, diverse stakeholders identified the top 10 research priorities for each of the categories male infertility, female and unexplained infertility, medically assisted reproduction and ethics, access and organization of care. PARTICIPANTS/MATERIALS, SETTING, METHODS: Healthcare professionals, people with fertility problems and others (healthcare funders, healthcare providers, healthcare regulators, research funding bodies and researchers) were brought together in an open and transparent process using formal consensus methods advocated by the James Lind Alliance. MAIN RESULTS AND THE ROLE OF CHANCE: The initial survey was completed by 388 participants from 40 countries, and 423 potential research questions were submitted. Fourteen clinical practice guidelines and 162 Cochrane systematic reviews identified a further 236 potential research questions. A rationalized list of 231 confirmed research uncertainties was entered into an interim prioritization survey completed by 317 respondents from 43 countries. The top 10 research priorities for each of the four categories male infertility, female and unexplained infertility (including age-related infertility, ovarian cysts, uterine cavity abnormalities and tubal factor infertility), medically assisted reproduction (including ovarian stimulation, IUI and IVF) and ethics, access and organization of care were identified during a consensus development meeting involving 41 participants from I I countries. These research priorities were diverse and seek answers to questions regarding prevention, treatment and the longer-term impact of infertility. They highlight the importance of pursuing research which has often been overlooked, including addressing the emotional and psychological impact of infertility, improving access to fertility treatment, particularly in lower resource settings and securing appropriate regulation. Addressing these priorities will require diverse research methodologies, including laboratory-based science, qualitative and quantitative research and population science. LIMITATIONS, REASONS FOR CAUTION: We used consensus development methods, which have inherent limitations, including the representativeness of the participant sample, methodological decisions informed by professional judgment and arbitrary consensus definitions. WIDER IMPLICATIONS OF THE FINDINGS: We anticipate that identified research priorities, developed to specifically highlight the most pressing clinical needs as perceived by healthcare professionals, people with fertility problems and others, will help research funding organizations and researchers to develop their future research agenda.
