Standard quality criteria in retracted vs nonretracted obstetrical randomized controlled trials

The number of retracted articles in peer-reviewed journals is increasing within the field of obstetrics. The most common reason for article retraction is scientific misconduct. Unfortunately, article retraction often occurs years after publication, allowing inaccurate data to be widely distributed to readers. There exists a great need for validated screening criteria for obstetric journals to use when reviewing randomized controlled trials for scientific misconduct. This study aimed to compare retracted obstetric randomized controlled trials with nonretracted randomized controlled trials with regard to their inclusion of 7 quality metrics: prospective trial registration, trial registration number, ethics approval statement, name of the approving committee, statement of informed consent, adherence to the Consolidated Standards of Reporting Trials guidelines, and a data sharing statement. Obstetric randomized controlled trials retracted between 1995 and 2021 identified through Retraction Watch were compared with nonretracted randomized controlled trials published between 2018 and 2020 with regard to inclusion of the 7 quality metrics. The main outcome was the difference in prospective trial registration. Secondary outcomes were the percentage of individual criteria met and the screening performance of quality criteria in predicting article retraction. A total of 150 randomized controlled trials were identified, of which 14 (9.3%) were retracted and 136 (90.7%) nonretracted. Retracted randomized controlled trials were less likely than nonretracted randomized controlled trials to be prospectively registered (14.3% vs 80.1%; P<.001). The median number of quality criteria met was lower for retracted randomized controlled trials (3 vs 6; P<.01). Using a cutoff of ≤4 criteria was associated with 85.7% (95% confidence interval, 57.2-98.2) sensitivity and 92.0% (95% confidence interval, 86.2-96.0) specificity in distinguishing the retracted randomized controlled trials from nonretracted studies. Retracted obstetric randomized controlled trials were less likely to include the 7 quality metrics required on submission by most top obstetrics and gynecology journals.

GRADE Use in Evidence Syntheses Published in High-Impact-Factor Gynecology and Obstetrics Journals: A Methodological Survey.

Objective: To identify and describe the certainty of evidence of gynecology and obstetrics systematic reviews (SRs) using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach. Method: Database searches of SRs using GRADE, published between 1 January 2016 to 31 December 2020, in the 10 "gynecology and obstetrics" journals with the highest impact factor, according to the Journal Citation Report 2019. Selected studies included those SRs using the GRADE approach, used to determine the certainty of evidence. Results: Out of 952 SRs, ninety-six SRs of randomized control trials (RCTs) and/or nonrandomized studies (NRSs) used GRADE. Sixty-seven SRs (7.04%) rated the certainty of evidence for specific outcomes. In total, we identified 946 certainty of evidence outcome ratings (n = 614 RCT ratings), ranging from very-low (42.28%) to low (28.44%), moderate (17.65%), and high (11.63%). High and very low certainty of evidence ratings accounted for 2.16% and 71.60% in the SRs of NRSs, respectively, compared with 16.78% and 26.55% in the SRs of RCTs. In the SRs of RCTs and NRSs, certainty of evidence was mainly downgraded due to imprecision and bias risks. Conclusions: More attention needs to be paid to strengthening GRADE acceptance and building knowledge of GRADE methods in gynecology and obstetrics evidence synthesis.

Bibliometric analysis of publications on COVID-19 and pregnancy from India

Introduction: There have been a large number of publications related to COVID-19 since the onset of the pandemic. Indian authors have not lagged. For a country like India, the outcomes of pregnancy are the very important measures of the development of the health-care system. Methods: All citations related to COVID-19 and pregnancy with at least an Indian author were extracted from Web Of Science. These were analysed used bibliometrix library in the R-environment. The analysis of content included word maps, thematic analysis, and most frequent word dendrograms. Results: A total of 145 documents were identified with an average citation rate of 2.29 per year. The maximum number of publications was in the International Journal of Gynecology and Obstetrics. A total of 875 authors were featured 1036 times across documents with the mean number of authors per document being 6.0. The corresponding author of these documents was from India in 127 (87.5%) manuscripts. A total of 460 author keywords, 211 “keyword plus” and all abstracts were analyzed and the output provided in graphical interfaces. Niche theme include stress and therapies for COVID-19 during pregnancies while a basic theme was risk to pregnancy. Motor themes were spread of infection, and SARS-CoV-2 binding to various tissues including foetal issue. Conclusion: This analysis reveals an active part taken by Indian authors in contribution to the world literature on COVID-19 during pregnancies. This is a surrogate marker for the importance being given to COVID-19 in pregnancy.Furthermore, we demonstrated persistent and emerging themes for these studies.

Imbalanced Incentives: A Content Analysis of research Participant Incentive Structures in Clinical and Translational Science.

In conducting research with underserved and vulnerable populations, incentives for research participants can improve recruitment efforts. However, incentives lose influence if researchers treat them as merely transactional. This study seeks to identify how researchers describe research participant incentives and incentive structures, with a focus on populations that experience health disparities. This study is a content analysis of research publications from peer-reviewed clinical journals. Although researchers share information about procedures through conference proceedings and grey literature, the most common mechanism for disseminating details about research studies is peer-reviewed literature. Sampling included research manuscripts from four journals (Annals of Family Medicine, Annals of Internal Medicine, American Journal of Emergency Medicine, American Journal of Obstetrics and Gynecology) within 2017-19. Within each issue, coders coded all manuscripts that the journal categorized as research. Using a deductive coding scheme, four authors sorted papers by research that enrolled participants versus other methods and then coded papers for variables of interest. Of 519 articles reviewed, 204 reported results to studies that enrolled human participants. Nine of these targeted populations that were vulnerable or experience disparities. Of 204 studies, 12 (5.9%) described an incentive for research participation. Participant type was significantly associated with offering a participant incentive, p < .001. Healthcare workers and online participants were more likely to receive an incentive than clinical research participants. Funding was also significantly associated with offering a participant incentive, p < .001, regardless of funding source. Of the 12 papers that disclosed incentive information, two focused on vulnerable populations. Findings here show few publications describe incentive structures, which indicates that either 1) incentives are underutilized in recruitment efforts or 2) studies are not publishing incentive information. Furthermore, incentives are more frequently used to recruit healthcare worker populations than community or clinical participants, which may indicate a transactional approach in contrast to a community or patient-oriented approach to research participation. A standardized approach to describing incentives could help researchers and clinicians contextualize a study's findings.

Trends, collaboration, and visibility of global scientific production on birth complications in pregnant women with tuberculosis: A scientometric study.

The increase in the number of pregnant women with tuberculosis is an important factor that should be analyzed at present. Thus, It is important to evaluate the bibliometric characteristics of the scientific production indexed in Scopus on complications of pregnancy and childbirth in pregnant women with tuberculosis. A cross-sectional bibliometric study was carried out analyzing the publications of journals indexed in Scopus between January 2016 and May 2022. A search strategy was developed using MESH terms and Boolean operators. The SciVal program (Elsevier) was used for bibliometric analysis of the information in the documents. Of the 287 publications analyzed, 13 were in the International Journal of Tuberculosis and Lung Disease and BJOG: An International Journal of Obstetrics and Gynaecology presented 11.9 citations per publication. Gupta Amita, from the United States, presented the most published papers; however, Myer London, from South Africa, had the highest impact, with 17.8 citations per publication. Johns Hopkins University was the institution with the highest number of publications (34). 51.9% of the publications were in journals in the Q1 quartile while 41.8% were international collaborations. In each year analyzed, scientific production was similar, with the highest proportion of publications in journals located in the Q1 and Q2 quartile. The institutions with the highest production were from the United States and South Africa. Therefore, there is a need to promote collaborative production in countries with greater presence of this disease.

The ABCs of a gynaecological teaching associate (GTA) programme

Gynaecological/Male Urogenital Teaching Associate (GTA/MUTA) methodology is considered the gold standard of invasive genital examination technique. Lay persons are trained in the technique of invasive genital examinations and patient-centred, trauma informed communication, and autonomously instruct learners on how to comfortably perform this examination using their own bodies as a teaching tool. GTAs/MUTAs function simultaneously as an autonomous instructor and a simulated patient during the exam. GTAs and MUTAs instruct clinical invasive examination techniques in a structured educational setting with a predetermined curriculum on which they have been trained, while letting learners perform these exam techniques on their bodies. Existing alternatives to GTA/MUTA education include the use of anesthetized patients, cadavers, plastic anatomical models (task trainers) and/or voluntary examinations on peers. There are unique benefits to the GTA/MUTA programme from both an institutional and learner perspective. Learner’s benefits unique to GTA/MUTA education include decreased learner anxiety [1], immediate feedback on examination technique with regard to patient’s physical comfort, and the opportunity to practise patient communication skills while performing such examinations. Institutional benefits unique to GTA/MUTA methodology are that after the initial setup cost, funds are saved removing the need for faculty to perform the examination instruction. Learner proficiency is higher compared to learners taught by physicians [1], and increased proficiency saves time and cost associated with learners being taken off clinical rotation to receive supplemental genital examination technique instruction. The use of simultaneous patient-instructors also introduces ‘elements of sensitivity and humanism’ to the examination [2] by having students learn to involve their patient and incorporate their perspective with regard to comfort and patient education information. By learning this examination from GTAs/MUTAs, a new model of physician patient relationship is taught, with GTAs/MUTAs functioning as informed collaborators rather than docile, uninformed patients [3]. In order to implement such a programme in an institution, among the first tasks is to obtain funding. This funding can be sought from grants or via institutional funds. Institutions may even choose to grow their GTA/MUTA programme to contract with outside institutions where this clinical examination instruction is needed. Other preparatory steps include establishing a curriculum, observing an established GTA/MUTA programme session to assess the format, and recruitment and training of GTAs and MUTAs. Once the programme is established, a clinical skills training day may be implemented. Implementing such a programme improves the learners’ experience and provides them with an increased understanding of sound technique that will benefit their patients in the long term. 1.

Editorial: Towards better and personalized management of ovarian cancer in China

Ovarian cancer remains the most lethal gynaecological malignancy worldwide, with 313 959 newly diagnosed cases and 207 252 deaths annually; approximately one-sixth of which occur in China.1 Despite the advances in the treatment of ovarian cancer, its 5-year survival rate has not surpassed 45%.2 In this supplement to the British Journal of Obstetrics and Gynaecology, eight manuscripts that focus on ovarian cancer therapy efficacy and consequences, therapeutic and prognostic biomarkers, shifts in treatment patterns, and establishment of big data gynaecological oncology platforms are included to outline the recent advances in our understanding of ovarian cancer management in China. Primary debulking surgery (PDS) followed by chemotherapy or neoadjuvant chemotherapy (NACT) and then interval debulking surgery (IDS) has been the standard of care for advanced epithelial ovarian cancer (EOC), and the absence of residual tumour after surgery is an important determinant of survival. Sun et al. summarised EOC-targeted fluorescent probes and open-field fluorescence imaging strategies to eradicate submillimetre and intraperitoneally scattered tumour masses to achieve complete resection. However, complete resection does not benefit all ovarian cancer subtypes. Liu et al. conducted a multicentre retrospective study and revealed that omentectomy did not improve survival and had no impact on pregnancy or live birth rates in apparently early malignant ovarian germ cell tumours. Therefore, prospective clinical trials are required to validate our conclusions. Intraperitoneally scattered tumour masses of ovarian cancer provide a rationale for the utilisation of intraperitoneal chemotherapy (IP). However, current randomised clinical trials failed to demonstrate the survival benefits of IP.3 Xiang et al. took advantage of the follow-up population of the AICE trial4 to conduct a treatment-free survival (TFS) analysis and demonstrated that patients with high tumour burden achieved significantly longer TFS and quality-adjusted overall survival (OS) compared with their counterparts with low tumour load when treated with IP followed by intravenous chemotherapy. Hyperthermic IP (HIPEC) after PDS improved the survival of EOC,5 but HIPEC in the neoadjuvant setting (NHIPEC) has not been sufficiently studied. Wu et al. demonstrated that NHIPEC plus NACT resulted in significantly prolonged progression-free survival (PFS) compared with NACT alone in patients with advanced high-grade serous ovarian cancer (HGSOC) in a retrospective study. Approximately 50% of HGSOC cases suffer from homologous recombination deficiency (HRD), which enables synthetic lethality with poly (ADP-ribose) polymerase (PARP) inhibition. Yuan et al. constructed a genomic scar model to predict HRD using machine learning algorithms, which demonstrated a sensitivity over 97% in detecting BRCA-deficient events and exhibited robustness in identifying responders to PARP inhibitors (PARPi). Treatment-naïve ovarian cancer often has a high response rate to platinum-based chemotherapy; however, platinum resistance inevitably emerges. Wu et al. revealed that co-expression of SLC7A11 and GPX4, two pivotal ferroptosis-related proteins, is significantly associated with platinum resistance and predicts worse PFS and OS. Liu et al. investigated the association among the primary treatment sequence (PDS versus NACT-IDS), recurrence characteristics, and post-relapse survival (PRS) based on real-world evidence. NACT-IDS was revealed as an independent risk factor for decreased PRS and was significantly associated with a shortened progression-free interval and a diffuse pattern of recurrence. China has the largest gynaecological oncology population worldwide and produces tremendous quantities of real-world disease- and treatment-related data. Zeng et al. established the National Union of Real-world Gynecological Oncology Research and Patient Management Platform (NUWA platform), the first large, scalable longitudinal clinico-genomic database in China that integrates multidimensional data on gynaecological oncology. They presented the implementation status and quality control methodology of the platform and leveraged the currently available data derived from 11 456 patients with ovarian cancer to display treatment pattern shifts in recent years. We are grateful to all the authors for their contributions and to British Journal of Obstetrics and Gynaecology for publishing this special issue. We believe that the contents of this issue will help readers understand the efforts of Chinese clinicians and researchers to facilitate better and personalised management of ovarian cancer in China.
