Actual Use of Rigid Hysteroscope Intrauterine BIGATTI Shaver (IBS<sup>®</sup>) with a Morcellator System

引用

Open Journal of Obstetrics and Gynecology 2021年第11期11卷 1494-1499页

作者： Toshiyuki Kakinuma Kaoru Kakinuma Ayano Shimizu Takahum Okusa Eri Suizu Masataka Kagimoto Masaki Abe koyomi saito Michitaka Ohwada Nobuhiro Takeshima Kaoru Yanagida Department of Obstetrics and Gynecology International University of Health and Welfare Hospital Iguchi Nasushiobara-City Tochigi Japan

Hysteroscopic resection of endometrial lesions has recently gained popularities. We here report the usefulness and safety of hysteroscopic surgery using Intrauterine BIGATTI Shaver (IBS®). We performed this surgery for 6 patients: 4 endometrial polyps and 2 intrauterine myoma. The average operation time was 25.7 ± 13.2 minutes. Only a small amount of bleeding was noted in all cases. There were no surgical complications. Two out of four patients who desired childbearing became pregnant. Hysteroscopic surgery using IBS® can safely and reliably remove intrauterine protruding lesions under aspiration without using a heat source. Less endometrial damage may help preserve fertility.

Exploiting open source omics data to advance pancreas research

胰腺病学杂志(英文) 2024年第1期7卷 21-27页

作者： Swaminathan Gayathri saito Toshie Husain Sohail Z. Division of Gastroenterology Hepatology and Nutrition Department of Pediatrics Stanford University School of Medicine Stanford CA

The "omics" revolution has transformed the biomedical research landscape by equipping scientists with the ability to interrogate complex biological phenomenon and disease processes at an unprecedented level. The volume of "big" data generated by the different omics studies such as genomics, transcriptomics, proteomics, and metabolomics has led to the concurrent development of computational tools to enable in silico analysis and aid data deconvolution. Considering the intensive resources and high costs required to generate and analyze big data, there has been centralized, collaborative efforts to make the data and analysis tools freely available as "Open Source," to benefit the wider research community. Pancreatology research studies have contributed to this "big data rush" and have additionally benefitted from utilizing the open source data as evidenced by the increasing number of new research findings and publications that stem from such data. In this review, we briefly introduce the evolution of open source omics data, data types, the "FAIR" guiding principles for data management and reuse, and centralized platforms that enable free and fair data accessibility, availability, and provide tools for omics data analysis. We illustrate, through the case study of our own experience in mining pancreatitis omics data, the power of repurposing open source data to answer translationally relevant questions in pancreas research.

The effect of ionospheric delay on the ground-based augmentation system under normal conditions can be mitigated by determining the value of the nominal ionospheric gradient(σvig).The nominal ionospheric gradient is generally obtained from Continuously Operating Reference Stations data by using the spatial single-difference method(mixed-pair,station-pair,or satellite-pair)or the temporal single-difference method(time-step).The time-step method uses only a single receiver,but it still contains ionospheric temporal *** introduce a corrected time-step method using a fixed-ionospheric pierce point from the geostationary equatorial orbit satellite and test it through simulations based on the global ionospheric *** also investigate the effect of satellite paths on the corrected time-step method in the region of the equator,which tends to be in a more north–south direction and to have less coverage for the east–west ionospheric *** study also addresses the limitations of temporal variation correction coverage and recommends using only the correction from *** processes are developed under simulations because observational data are still difficult to *** findings demonstrate that the corrected time-step method yieldsσvig values consistent with other approaches.

Education Programs for Invasive Procedures Involving Nurses: A Scoping Review

Background: Implementing invasive procedures is an important part of patient management by clinical nurses;however, there are gaps between nurses’ actual knowledge and skills and expected professional care capacity. Purpose: This scoping review aimed to map the existing literature related to recent institution-provided educational programs for invasive procedures involving clinical nurses. This study seeks to understand the contents of educational programs and the methods for assessing educational effects. Methods: This scoping review was completed using the following four databases: PubMed (MEDLINE), Embase, Cochrane Library, and Emcare for the period 2000-2022. We included studies that used all forms of educational approaches (e.g., didactic lectures, hands-on training, or on-the-job training). This scoping review considered peer-reviewed publications published in English using quantitative, qualitative, or mixed approaches. A total of 83 studies underwent in the final analysis. Results and Conclusion: A combination of didactic lectures and hands-on training was provided as an educational program in most studies. Contrary to our prediction, educational interventions with advanced technologies such as VR are extremely rare, suggesting that the effectiveness of advanced technologies in learning invasive procedures should be examined to facilitate and retain educational effects more efficiently in future studies. Regarding the assessment of educational effects, nurses’ cognitive (i.e., theoretical knowledge about procedures), psychomotor (i.e., implementing procedures), and psychological aspects (e.g., confidence and self-efficacy in procedures) were evaluated using questionnaires and observational methods. While most studies used a one-group pretest-posttest design, the ratio of randomized controlled trials (RCT) was relatively low. Thus, an RCT design should be introduced in future studies to test the validity of the developed educational program more accurately.
