Introduction Gender disparities exist in the OBGYN discipline. This study investigates, for the first time, whether gender impacts on the confidence of practical and surgical skills among OBGYN residents, and of being prepared to work as a specialist. Methods The gynecological societies of Austria, Germany, and Switzerland established a web-based survey of 30 questions that was sent to all registered OBGYN members-in-training from August to September 2020. Data collection, controlling and analysis were performed by the Swiss Federal Institute of Technology in Zurich (ETH). Results A total of 422 participants took part in the survey, of which 375 (88.9%) were female, 46 (10.9%) were male, and one (0.2%) was divers. The diverse participant was excluded from further analyses. The gender distribution was comparable in all three countries. Multiple regression analyses showed that gender is an independent variable significantly impacting on the confidence levels in performing standard gynaecological ( p  = 0.03) and obstetric ( p  < 0.001) procedures. Similarly, the feeling of confidence in being prepared for working as a specialist in a clinic showed to be gender-dependent ( p  < 0.001), however, not the feeling of being prepared for working as specialist in an outpatient setting ( p  = 0.37). The “female factor” significantly decreases the confidence rating for surgical and practical skills and for working in a hospital. Covariates including year of training, country, workload, receiving regular feedback, and implemented simulation training were included in all analyses. Discussion Improvements of residency programs to promote female doctors to overcome factors reducing their confidence in their own OBGYN skills are highly warranted.

BackgroundC reactive protein (CRP) kinetics have recently been suggested as predictive biomarkers for the efficacy of immune checkpoint inhibitor (ICI) therapy in selected cancer types. The aim of this study was to characterize early CRP kinetics as a tumor-agnostic biomarker for ICI treatment outcomes.MethodsIn this multicenter retrospective cohort study, two independent cohorts of patients with various cancer types undergoing palliative ICI treatment at Austrian academic centers served as the discovery (n=562) and validation cohort (n=474). Four different patterns of CRP kinetics in the first 3 months of ICI therapy were defined (CRP-flare responders, CRP-responders, CRP non-responders, patients with all-normal CRP). Objective response rate (ORR), progression-free survival (PFS) and overall survival (OS) were defined as coprimary endpoints. Univariable and multivariable logistic regression, landmark analysis and Cox regression including CRP kinetics as time-dependent variable were performed.ResultsThe ORR in patients with all-normal CRP, CRP responders, CRP flare-responders and CRP non-responders was 41%, 38%, 31% and 12%, respectively. The median OS and PFS estimates were 24.5 months (95% CI 18.5 to not reached) and 8.2 months (95% CI 5.9 to 12.0) in patients with all-normal CRP, 16.1 months (95% CI 12.6 to 19-8) and 6.1 months (95% CI 4.9 to 7.2) in CRP-responders, 14.0 months (95% CI 8.5 to 19.4) and 5.7 months (95% CI 4.1 to 8.5) in CRP flare-responders and 8.1 months (95% CI 5.8 to 9.9) and 2.3 months (95% CI 2.2 to 2.8) in CRP non-responders (log-rank p for PFS and OS<0.001). These findings prevailed in multivariable analysis and could be fully confirmed in our validation cohort. Pooled subgroup analysis suggested a consistent predictive significance of early CRP kinetics for treatment efficacy and outcome independent of cancer type.ConclusionEarly CRP kinetics represent a tumor-agnostic predictor for treatment response, progression risk and mortality in patients with cancer undergoing ICI therapy.
