Purpose: Hysteroscopy can be used both to diagnose and to treat intrauterine pathologies. It is well known that hysteroscopy helps to improve reproductive outcomes by treating intrauterine pathologies. However, it is uncertain whether hysteroscopy is helpful in the absence of intrauterine pathologies. This study aimed to confirm whether hysteroscopy improves the reproductive outcomes of infertile women without intrauterine pathologies.Methods: We conducted a systematic review of 11 studies retrieved from Ovid-MEDLINE, Ovid-Embase, and the Cochrane Library. Two independent investigators extracted the data and used risk-of-bias tools (RoB 2.0 and ROBINS-I) to assess their quality.Results: Diagnostic hysteroscopy prior to in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) was associated with a higher clinical pregnancy rate (CPR) and live birth rate (LBR) than non-hysteroscopy in patients with recurrent implantation failure (RIF) (odds ratio, 1.79 and 1.46; 95% confidence interval, 1.40–2.30 and 1.08–1.97 for CPR and LBR, respectively) while hysteroscopy prior to first IVF was ineffective. The overall meta-analysis of LBR showed statistically significant findings for RIF, but a subgroup analysis showed effects only in prospective cohorts (odds ratio, 1.40 and 1.47; 95% confidence interval, 0.86–1.56 and 1.04–2.07 for randomized controlled trials and prospective cohorts, respectively). Therefore, the LBR should be interpreted carefully and further research is needed. Conclusion: Although further research is warranted, hysteroscopy may be considered as a diagnostic and treatment option for infertile women who have experienced RIF regardless of intrauterine pathologies. This finding enables nurses to educate and support infertile women with RIF prior to IVF/ICSI.

Background Lifestyle modification is the primary treatment for overweight and obese women with polycystic ovarian syndrome (PCOS). Developing mobile applications that motivate and provide lifestyle modification advice and evidence‐based information for women with PCOS is needed. Aims This study is aimed at the development of an integrated mobile application for lifestyle modifications in women with PCOS. Methods This study is a development study to develop a lifestyle modification mobile application for PCOS based on a systematic review and needs analysis according to the ADDIE model. The survey was conducted consecutively on patients with PCOS who visited a university hospital in Incheon, Republic of Korea from 1 November 2020 to 28 February 2021. The questionnaire was developed based on prior literature, and validity was evaluated by experts. The survey investigated respondents’ general characteristics, the perceptions and needs, and the preferred components of integrated mobile application for lifestyle modification. The usability of the application was evaluated by experts. STROBE statement has been followed in this study. Results The lifestyle modification programme was confirmed to be clinical effect through a systematic review. The necessity application and high scores in preference of all components was confirmed in a survey. The mobile application included every amount of intake, exercise time, menstrual period, and daily weight compared with the target weight and BMI. It also included questionnaires on hirsutism and acne, disease information, and communication with the researcher for counselling purposes. The application will motivate users to participate by giving scores according to a goal achievement each day. In usability test, experts evaluate this mobile application as suitable for use. Conclusion In this study, an integrated mobile application was developed in consideration of the systematic review and needs analysis of women with PCOS. The effectiveness of the application will need to be verified through further research. Relevance to clinical practice This study developed an integrated mobile application including diet and exercise therapy, as well as weight and menstrual period management, questionnaires and disease information. In addition, the mobile application motivates women with PCOS to provide personalised counselling and achieve goals. We expect to use it in future studies for women with PCOS in clinical practice.

(1) Background: The aim of this work was to systematically review existing studies on whether hysteroscopy improves the reproductive outcomes of women with infertility even in the absence of intrauterine pathologies when compared to women who did not receive a hysteroscopy. (2) Methods: We established the Participant-Intervention-Comparison-Outcome strategy and used the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement to conduct a systematic review of 11 studies which were retrieved from 3 electronic databases: Ovid-Medline, Ovid-Embase, and the Cochrane Library. Two independent investigators extracted the data from the included studies and used the Cochrane risk-of-bias tool to assess their quality. (3) Results: The primary outcome measures were the clinical pregnancy rates (CPRs) and live birth rates (LBRs) in the in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) cycles. Hysteroscopy in infertile women without intrauterine pathologies showed higher CPRs and LBRs than those in the same population who did not receive hysteroscopy in cases of recurrent implantation failure and IVF (odds ratio: 1.79 and 1.46, 95% confidence interval: 1.46-2.30 and 1.08-1.97 for CPR and LBR, respectively); however, the degree of significance was not as high for LBR. (4) Conclusions: Hysteroscopy before IVF/ICSI in infertile women without intrauterine pathologies may potentially be effective in improving the CPRs and LBRs in patients with RIF. Robust and high-quality randomized trials are warranted to confirm this finding.
