Artificial intelligence model for enhancing the accuracy of transvaginal ultrasound in detecting endometrial cancer and endometrial atypical hyperplasia.

OBJECTIVES: Transvaginal ultrasound is typically the initial diagnostic approach in patients with postmenopausal bleeding for detecting endometrial atypical hyperplasia/cancer. Although transvaginal ultrasound demonstrates notable sensitivity, its specificity remains limited. The objective of this study was to enhance the diagnostic accuracy of transvaginal ultrasound through the integration of artificial intelligence. By using transvaginal ultrasound images, we aimed to develop an artificial intelligence based automated segmentation model and an artificial intelligence based classifier model. METHODS: Patients with postmenopausal bleeding undergoing transvaginal ultrasound and endometrial sampling at Mayo Clinic between 2016 and 2021 were retrospectively included. Manual segmentation of images was performed by four physicians (readers). Patients were classified into cohort A (atypical hyperplasia/cancer) and cohort B (benign) based on the pathologic report of endometrial sampling. A fully automated segmentation model was developed, and the performance of the model in correctly identifying the endometrium was compared with physician made segmentation using similarity metrics. To develop the classifier model, radiomic features were calculated from the manually segmented regions-of-interest. These features were used to train a wide range of machine learning based classifiers. The top performing machine learning classifier was evaluated using a threefold approach, and diagnostic accuracy was assessed through the F1 score and area under the receiver operating characteristic curve (AUC-ROC). RESULTS: 302 patients were included. Automated segmentation-reader agreement was 0.79±0.21 using the Dice coefficient. For the classification task, 92 radiomic features related to pixel texture/shape/intensity were found to be significantly different between cohort A and B. The threefold evaluation of the top performing classifier model showed an AUC-ROC of 0.90 (range 0.88-0.92) on the validation set and 0.88 (range 0.86-0.91) on the hold-out test set. Sensitivity and specificity were 0.87 (range 0.77-0.94) and 0.86 (range 0.81-0.94), respectively. CONCLUSIONS: We trained an artificial intelligence based algorithm to differentiate endometrial atypical hyperplasia/cancer from benign conditions on transvaginal ultrasound images in a population of patients with postmenopausal bleeding.

The Impact of Dobbs on US Graduate Medical Education.

The Dobbs decision will directly affect patients and reproductive rights; it will also impact patients indirectly in many ways, one of which will be changes in the physician workforce through its impact on graduate medical education. Current residency accreditation standards require training in all forms of contraception in addition to training in the provision of abortion. State bans on abortions may diminish access to training as approximately half of obstetrics and gynecology residency programs are in states with significant abortion restrictions. The Dobbs decision creates numerous hurdles for trainees and their programs. Trainees in restrictive states will have to travel to learn in a different program in a protective state. As training opportunities diminish, potentially leading to a decline in clinical skills, knowledge, and experience in the provision of abortion, the rate of complications and maternal mortality are likely to rise. This will likely have a disproportionately negative effect on preexisting disparities in reproductive health fueled by a longstanding history of systemic racism and inequities. This work aims to both define the looming problem in abortion training created by Dobbs and propose solutions to ensure that an adequate workforce is available in the future to serve patient needs.

What are essential laparoscopic skills these days? Results of the SAGES Fundamentals of Laparoscopic Surgery (FLS) Committee technical skills survey.

INTRODUCTION: The Fundamentals of Laparoscopic Surgery (FLS) program tests basic knowledge and skills required to perform laparoscopic surgery. Educational experiences in laparoscopic training and development of associated competencies have evolved since FLS inception, making it important to review the definition of fundamental laparoscopic skills. The Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) assigned an FLS Technical Skills Working Group to characterize technical skills used in basic laparoscopic surgery in current practice contexts and their possible application to future FLS tests. METHODS: A group of subject matter experts defined an inventory of 65 laparoscopic skills using a Nominal Group Technique. From these, a survey was developed rating these items for importance, frequency of use, and priority for testing for FLS certification. This survey was distributed to SAGES members, recent recipients of FLS certification, and members of the Association of Program Directors in Surgery (APDS). Results were collected using a secure web-based survey platform. RESULTS: Complete data were available for 1742 surveys. Of these, 1143 comprised results for post-residency participants who performed advanced procedures. Seventeen competencies were identified for FLS testing prioritization by determining the proportion of respondents who identified them of highest priority, at median (50th percentile) of the maximum survey scale rating. These included basic peritoneal access, laparoscope and instrument use, tissue manipulation, and specific problem management skills. Sixteen could be used to show appropriateness of the domain construct by confirmatory factor analysis. Of these 8 could be characterized as manipulative tasks. Of these 5 mapped to current FLS tasks. CONCLUSIONS: This survey-identified competencies, some of which are currently assessed in FLS, with a high level of priority for testing. Further work is needed to determine if this should prompt consideration of changes or additions to the FLS technical skills test component.

Levels of Gynecologic Care: A Task Force Consensus Statement.

Systems of care have been established for obstetrics, trauma, and neonatology. An American College of Obstetricians and Gynecologists Presidential Task Force was established to develop a care system for gynecologic surgery. A group of experts who represent diverse perspectives in gynecologic practice proposed definitions of levels of gynecologic care using the Delphi method. The goal is to improve the quality of gynecologic surgical care performed in the United States by providing a framework of minimal institutional requirements for each level. Subgroups developed draft criteria for each level of care. The entire Task Force then met to reach consensus regarding the levels of care final definitions and parameters. The levels of gynecologic care framework focuses on systems of care by considering institutional resources and expertise, providing guidance on the provision of care in appropriate level facilities. These levels were defined by the ability to care for patients of increasing risk, complexity, and comorbidities, organizing gynecologic care around hospital capability. This framework can also be used to inform the escalation of care to appropriate facilities by identifying patients at risk and guiding them to facilities with the skills, expertise, and capabilities to safely and effectively meet their needs. The levels of gynecologic care framework is intended for use by patients, hospitals, and clinicians in the United States to guide where elective surgery can be done most safely and effectively by specialists and subspecialists in obstetrics and gynecology. The key features of the levels of gynecologic care include ensuring provision of risk-appropriate care and regionalization of care by facility capabilities.

Virtual residency recruitment: future directions in the new era.

INTRODUCTION: The COVID-19 pandemic led to many changes in healthcare including graduate medical education (GME). Residency and fellowship programs halted in-person recruitment and pivoted to virtual models. Residency selection and recruitment were practices ripe for redesign, as they relied on in-person interviewing as the major point of contact prior to match list creation. In this commentary, we review the state of virtual interviewing and propose a future state where virtual interactions are commonplace and integrated into a comprehensive recruitment process. DISCUSSION: Virtual recruitment has led to a reduction of expenses, improved time efficiency for all parties and a reduced carbon footprint. Residency match outcomes have not changed substantially with the advent of virtual interviewing. Hybrid approaches, including virtual and in-person options have significant drawbacks and pitfalls which may limit adoption. Given the upheaval in GME recruitment caused by the pandemic, and the limitations of current methods for candidate assessment and interactions with programs, further innovation is needed to achieve an optimal state for all stakeholders. Multiple technology innovations are on the horizon which may improve the ability to interact virtually. Adoption of new technology along with expanding the timeline for residency recruitment may further optimize the process for both applicants and programs. CONCLUSIONS: The GME community was able to adopt technology for the recruitment interview rapidly due to the pandemic. As more opportunities for technology-based interactions grow, the opportunity exists to reimagine recruitment beyond the interview. While resources are constrained, some of the efficiencies gained by adopting virtual interviewing can be leveraged to expand the interactions between programs and applicants. Incorporation of in-person interaction may still be needed. Models will need to be developed to build upon the best characteristics of the virtual and in-person environments to optimize GME recruitment.KEY MESSAGES:Virtual communication methods have substantially changed residency recruitment during the COVID -19 pandemic.COVID -19 related changes in residency recruitment, including wide adoption of virtual methods, should be maintained and strengthened.Efforts should be made to advance the gains in residency recruitment strategy during the pandemic by use of technologies that expand virtual interactions beyond the interview.

Impact of Question Bank Use for In-Training Examination Preparation by OBGYN Residents - A Multicenter Study.

OBJECTIVE: To examine the impact of access to and utilization of a commercially available question bank (TrueLearn) for in-training examination (ITE) preparation in Obstetrics and Gynecology (OBGYN). DESIGN: This was a retrospective cohort study examining the impact of TrueLearn usage on ITE examination performance outcomes. Produced by the educational arm of the American College of Obstetricians and Gynecologists, the Council on Resident Education in Obstetrics and Gynecology (CREOG) exam is a multiple-choice test given to all residents annually. Residency programs participating in this study provided residency program mean CREOG scores from the year prior (2015), and the first (2016) and second (2017) years of TrueLearn usage. Programs also contributed resident-specific CREOG scores for each resident for 2016 and 2017. This data was combined with each resident's TrueLearn usage data that was provided by TrueLearn with residency program consent. The CREOG scores consisted of the CREOG score standardized to all program years, the CREOG score standardized to the same program year (PGY) and the total percent (%) correct. TrueLearn usage data included number of practice questions completed, number of practice tests taken, average number of days between successive tests, and percent correct of answered practice questions. SETTING: OBGYN Residency Training Programs. PARTICIPANTS: OBGYN residency programs that purchased and utilized TrueLearn for the 2016 CREOG examination were eligible for participation (n = 14). Ten residency programs participated, which consisted of 212 residents in 2016 and 218 residents in 2017. RESULTS: TrueLearn was used by 78.8% (167/212) of the residents in 2016 and 84.9% (185/218) of the residents in 2017. No significant difference was seen in the average CREOG scores available on a per- program level before versus after the first year of implementation either using the CREOG score standardized to all PGYs (mean difference 1.0; p = 0.58) or standardized to the same PGY (mean difference 3.1; p = 0.25). Using resident-level data, there was no significant difference in mean CREOG score standardized to all PGYs between users and non-users of TrueLearn in 2016 (mean, 199.4 vs 196.7; p = 0.41) or 2017 (mean, 198.2 vs 203.4; p = 0.19). The percent of practice questions answered correctly on TrueLearn was positively correlated with the CREOG score standardized to all PGYs (r = 0.47 for 2016 and r = 0.60 for 2017), as well as with the CREOG total percent correct (r = 0.47 for 2016 and r = 0.61 for 2017). Based on a simple linear regression, for every 500 practice questions completed, the CREOG score significantly increased for PGY-2 residents by an average (±SE) of 7.3 ± 2.8 points (p = 0.013); the average increase was 0.7 ± 2.5 (p = 0.79) for PGY-3 residents and 5.8 ± 3.3 points (p = 0.09) for PGY-4 residents. CONCLUSIONS: Adoption of an online question bank did not result in higher mean CREOG scores at participating institutions. However, performance on the TrueLearn questions correlated with ITE performance, supporting predictive validity and the use of this question bank as a formative assessment for resident education and exam preparation.

Lateral decubitus position to facilitate pelvic examination of the patient with severe obesity.

BACKGROUND: Patients with elevated BMI pose a number of challenges for the gynecologist. Pelvic examination may be more difficult due to adiposity in the perineum and labia, increasing the distance between the vulva and cervix. The objective of the current work was to describe use of the lateral decubitus position to improve visualization of the cervix in women with severe obesity. METHODS: A case series was collected. From 7/1/2010 until 1/31/2020, all records of patients with obesity and unsuccessful cervical visualization during pelvic exam in the dorsal lithotomy position in the author's clinical practice were reviewed after obtaining Mayo Clinic Institutional Review Board approval. For the lateral decubitus position, the patient was asked to lie on her side on the exam table, facing away from the examiner with knees bent. An assistant elevated the upper bent leg 45 degrees from horizontal, exposing the perineum. A vaginal speculum was then placed in the vagina with the posterior blade toward the anus. The speculum was opened gently as would be done with examination in dorsal lithotomy position until the cervix was visualized. RESULTS: Eleven patients with severe obesity in the gynecologic practice of the author with prior unsuccessful cervical visualization in dorsal lithotomy position were examined in the lateral decubitus position. In all but one case the cervix was successfully visualized in the lateral decubitus position and all intended intrauterine procedures were successfully performed. CONCLUSIONS: In this case series, the use of the lateral decubitus position appears to improve visualization of the cervix in the outpatient setting among women with severe obesity. Consideration should be given to use of the lateral decubitus position when the cervix cannot be visualized in the dorsal lithotomy position.

The nucleic acid binding protein YB-1-controlled expression of CXCL-1 modulates kidney damage in liver fibrosis.

Acute kidney injury is a common complication of advanced liver disease and increased mortality of these patients. Here, we analyzed the role of Y-box protein-1 (YB-1), a nucleic acid binding protein, in the bile duct ligation model of liver fibrosis and monitored liver and subsequent kidney damage. Following bile duct ligation, both serum levels of liver enzymes and expression of hepatic extracellular matrix components such as type I collagen were significantly reduced in mice with half-maximal YB-1 expression (Yb1+/-) as compared to their wild-type littermates. By contrast, expression of the chemokine CXCL1 was significantly augmented in these Yb1+/- mice. YB-1 was identified as a potent transcriptional repressor of the Cxcl1 gene. Precision-cut kidney slices from Yb1+/- mice revealed higher expression of the CXCL1 receptor CXCR2 as well as enhanced responsivity to CXCL1 compared to those from wild-type mice. Increased CXCL1 content in Yb1+/- mice led to pronounced bile duct ligation-induced damage of the kidneys monitored as parameters of tubular epithelial injury and immune cell infiltration. Pharmacological blockade of CXCR2 as well as application of an inhibitory anti-CXCL1 antibody significantly mitigated early systemic effects on the kidneys following bile duct ligation whereas it had only a modest impact on hepatic inflammation and function. Thus, our analyses provide direct evidence that YB-1 crucially contributes to hepatic fibrosis and modulates liver-kidney crosstalk by maintaining tight control over chemokine CXCL1 expression.

The YB-1:Notch-3 axis modulates immune cell responses and organ damage in systemic lupus erythematosus.

Systemic lupus erythematosus (SLE) is an autoimmune disease and lupus nephritis is a major risk factor for morbidity and mortality. Notch-3 signaling induced by membrane-bound or soluble ligands such as YB-1 constitutes an evolutionarily conserved pathway that determines major decisions in cell fate. Mass spectrometry of extracellular YB-1 in sera from patients with SLE and lupus-prone mice revealed specific post-translational guanidinylation of two lysine residues within the highly conserved cold-shock domain of YB-1 (YB-1-G). These modifications highly correlated with SLE disease activity, especially in patients with lupus nephritis and resulted in enhanced activation of Notch-3 signaling in T lymphocytes. The importance of YB-1:Notch-3 interaction in T cells was further evidenced by increased interleukin (Il)10 expression following YB-1-G stimulation and detection of both, YB-1-G and Notch-3, in kidneys of MRL.lpr mice by mass spectrometry imaging. Notch-3 expression and activation was significantly up-regulated in kidneys of 20-week-old MRL.lpr mice. Notably, lupus-prone mice with constitutional Notch-3 depletion (B6.Faslpr/lprNotch3-/-) exhibited an aggravated lupus phenotype with significantly increased mortality, enlarged lymphoid organs and aggravated nephritis. Additionally, these mice displayed fewer regulatory T cells and reduced amounts of anti-inflammatory IL-10. Thus, our results indicate that the YB-1:Notch-3 axis exerts protective effects in SLE and that Notch-3 deficiency exacerbates the SLE phenotype.

Use of High-Fidelity Simulation to Enhance Interdisciplinary Collaboration and Reduce Patient Falls.

OBJECTIVES: This pilot study aimed to determine the effect of nurse/physician interdisciplinary team training on patient falls. Specifically, we evaluated team training in a simulation center as a method for targeting and minimizing breakdowns in perceptions of respect, collaboration, communication, and role misunderstanding behaviors between care disciplines. METHODS: Registered nurses (RNs) were randomly assigned to participate. Residents were divided into groups and assigned based on their availability and clinical responsibility. All participants completed a demographic form, the Professional Practice Environment Assessment Scale (PPEAS), and the Mayo High Performance Teamwork Scale (MHPTS) after consenting and before participation in simulation training. The PPEAS and the MHPTS were readministered at 2 and 6 months after the simulation experience. Differences in MHPTS and PPEAS scores between the baseline and 2- and 6-month assessments were analyzed; fall rates over time were evaluated using Cochran-Armitage trend tests. RESULTS: After the team training exercises, teamwork as measured by the MHPTS improved significantly at both 2 and 6 months (P = 0.01; P < 0.001) compared with baseline measurement. Practice environment subscores, with the exception of positive organizational characteristics, also increased when measured 6 months after training. The primary outcome, reduction in anticipated patient falls, improved significantly (P = 0.02) over the course of the study. CONCLUSIONS: Results of this pilot study show that team training exercises result in improvement in both patient safety (anticipated patient falls) and team member perception of their work environment. If validated by other studies, improvement in this patient safety metric would represent an important benefit of simulation and team training.

Improving patient access through office hysteroscopy clinic redesign.

BACKGROUND AND OBJECTIVE: Patients with abnormal uterine bleeding (AUB) often require hysteroscopy as part of the diagnostic workup. The purpose of this study was to improve efficiency by shortening the time to patient appointment for office hysteroscopy. INTERVENTIONS: Preintervention, nurse practitioners (NPs) and gynecologists saw patients with abnormal uterine bleeding (AUB) separately. This created inefficiency for the patients, frequently requiring second visits for hysteroscopy. A new hysteroscopy clinic was designed to increase practice efficiency. A collaborative team model was created including consecutive visits with NPs and gynecologists. Each patient with AUB was first evaluated by an NP, followed immediately by a shorter visit with a gynecologist for office hysteroscopy as indicated. NPs managed other diagnostic evaluation and bleeding treatment if hysteroscopy was not warranted. Collaborative clinic staffing consisted of two NPs seeing patients with AUB paired with one gynecologist for procedural support. MEASUREMENTS AND RESULTS: Electronic records of 393 patients scheduled for AUB visits from January to June 2015 were evaluated for preintervention data. Postintervention, 647 patient records were reviewed from January to June of 2016. During the preintervention period, 30% of patients had a hysteroscopy appointment scheduled within 0-13 days from the initial visit for AUB. Postintervention, the wait time for appointments decreased, with 63% of patients scheduled within 0-13 days. Clinic redesign also resulted in an increase of 57.5% in appointment slots. No-show rates and appointment fill rates were not adversely affected. CONCLUSIONS: A collaborative team-based care model using NPs and gynecologists improved efficiency and access to office hysteroscopy services.

Use of Asynchronous Video Interviews for Selecting Obstetrics and Gynecology Residents.

OBJECTIVE: To assess the effect of using of asynchronous video interviewing as a screening tool for obstetrics and gynecology residency selection. METHODS: This project was part of a quality-improvement effort to enhance the resident application process. Applications to a single obstetrics and gynecology residency program were scored using standardized criteria. In the 2018 Match, top-scored applicants were invited to in-person interviews, and second-tier applicants were asked to complete a three-question asynchronous video interview. Video interviews were scored and used to invite the remaining applicants for in-person interviews. In the 2019 Match, video interviewing was expanded to all applicants with top application scores, and the video score was used to determine in-person interview invitations. Applicants for 2019 were surveyed on their views regarding video interviewing. RESULTS: Half of the candidates interviewed in person in the 2018 season were screened by the video interview process compared with 82% in the 2019 season. The mean in-person interview score increased from 59.0 in 2017, before screening with asynchronous video interviews, to 62.2 in 2018 (effect size 0.50; 95% CI 0.09-0.90) In 2018, a nonsignificant correlation was seen between the video interview score and rank list percentile (r=0.22, P=.15, n=27) and in-person interview score (r=0.18, P=.12, n=46). United States Medical Licensing Examination step 1 and 2 scores were not correlated with video interview scores in either season. Most (58%) candidates indicated that the asynchronous video interview was an effective way to tell their story; however, only 42% were comfortable with the interview process. CONCLUSION: Video interviewing may have promise as a tool for program directors to use to select candidates from a competitive applicant pool by measuring important noncognitive skills. Acceptance by obstetrics and gynecology applicants was mixed.

What makes a chronic pelvic pain patient satisfied?

Purpose: Caring for women with chronic pelvic pain (CPP) is challenging. There have been few studies on what factors patients consider to be important when being treated for their pelvic pain. This study sought to identify the key factors of the health care visit that contribute to patient's overall satisfaction with their care in a CPP clinic. Materials and methods: Between January 2015 and December 2016, new patients visiting a tertiary care CPP clinic were recruited to complete a patient satisfaction survey. Inductive thematic analysis was performed on response data regarding important factors that impact patient satisfaction with their visit/care. Results: Five themes of patient satisfaction identified included: providers with a compassionate and caring attitude, being listened to, clear communication with collaboration when needed, quality time spent with patient, and having a plan of care with recommendations. The theme regarding provider's compassion and listening skills was the most frequently identified. Pain relief was seldom mentioned as a source of patient satisfaction. Conclusions: The data suggest that a focus on empathic communication may make a meaningful difference in meeting the needs of women with CPP as well as strengthening the provider/patient relationship.

YB-1 increases glomerular, but decreases interstitial fibrosis in CNI-induced nephropathy.

Calcineurin inhibitors (CNIs) are a cornerstone of the current treatment in solid organ transplantation and autoimmune disease. However, CNIs also bear deleterious effects as they cause glomerular and tubulointerstitial fibrosis in the kidney. We recently identified Y-box protein-1 (YB-1) as a novel downstream effector of CNI-signaling in the cytoplasm of glomerular cells. In the present study, we corroborate the pro-fibrotic role of YB-1 in glomeruli of patients under CNI-treatment. Such effects in glomeruli are significantly mitigated in CNI-treated mice with half-normal YB-1 expression (Yb1+/-). Surprisingly, in the tubulointerstitium we observe an opposite role of the CNI-YB-1 axis. Here, YB-1 is predominantly located to the nuclei and represses transcription of several extracellular matrix genes. Consistently, CNI-treatment in Yb1+/- mice markedly increases pro-fibrotic changes in the tubulointerstitium. In summary, our data provide evidence that fibrotic CNI-induced YB-1 effects in glomerular cells need to be contrasted with beneficial anti-fibrotic effects in the tubulointerstitium.

Medical therapy versus radiofrequency endometrial ablation in the initial treatment of heavy menstrual bleeding (iTOM Trial): A clinical and economic analysis.

BACKGROUND: Radiofrequency endometrial ablation (REA) is currently a second line treatment in women with heavy menstrual bleeding (MHB) if medical therapy (MTP) is contraindicated or unsatisfactory. Our objective is to compare the effectiveness and cost burden of MTP and REA in the initial treatment of HMB. METHODS: We performed a randomized trial at Mayo Clinic Rochester, Minnesota. The planned sample size was 60 patients per arm. A total of 67 women with HMB were randomly allocated to receive oral contraceptive pills (Nordette ®) or Naproxen (Naprosyn®) (n = 33) or REA (n = 34). Primary 12-month outcome measures included menstrual blood loss using pictorial blood loss assessment chart (PBLAC), patients' satisfaction, and Menorrhagia Multi-Attribute Scale (MMAS). Secondary outcomes were total costs including direct medical and indirect costs associated with healthcare use, patient out-of-pocket costs, and lost work days and activity limitations over 12 months. RESULTS: Compared to MTP arm, women who received REA had a significantly lower PBLAC score (median [Interquartile range, IQR]: 0 [0-4] vs. 15 [0-131], p = 0.003), higher satisfaction rates (96.8%vs.63.2%, p = 0.003) and higher MMAS (median [IQR]: 100 [100-100] vs. 100 [87-100], p = 0.12) at 12 months. Direct medical costs were higher for REA ($5,331vs.$2,901, 95% confidence interval (CI) of mean difference:$727,$4,852), however, when indirect costs are included, the difference did not reach statistical significance ($5,469 vs. $3,869, 95% CI of mean difference:-$339, $4,089). CONCLUSION: For women with heavy menstrual bleeding, initial radiofrequency endometrial ablation compared to medical therapy offered superior reduction in menstrual blood loss and improvement in quality of life without significant differences in total costs of care. CLINICAL TRIAL REGISTRATION: NCT01165307.

YB-1 orchestrates onset and resolution of renal inflammation via IL10 gene regulation.

The Y-box-binding protein (YB)-1 plays a non-redundant role in both systemic and local inflammatory response. We analysed YB-1-mediated expression of the immune regulatory cytokine IL-10 in both LPS and sterile inflammation induced by unilateral renal ischaemia-reperfusion (I/R) and found an important role of YB-1 not only in the onset but also in the resolution of inflammation in kidneys. Within a decisive cis-regulatory region of the IL10 gene locus, the fourth intron, we identified and characterized an operative YB-1 binding site via gel shift experiments and reporter assays in immune and different renal cells. In vivo, YB-1 phosphorylated at serine 102 localized to the fourth intron, which was paralleled by enhanced IL-10 mRNA expression in mice following LPS challenge and in I/R. Mice with half-maximal expression of YB-1 (Yb1+/- ) had diminished IL-10 expression upon LPS challenge. In I/R, Yb1+/- mice exhibited ameliorated kidney injury/inflammation in the early-phase (days 1 and 5), however showed aggravated long-term damage (day 21) with increased expression of IL-10 and other known mediators of renal injury and inflammation. In conclusion, these data support the notion that there are context-specific decisions concerning YB-1 function and that a fine-tuning of YB-1, for example, via a post-translational modification regulates its activity and/or localization that is crucial for systemic processes such as inflammation.

Clinical Manifestations and Outcomes in Surgically Managed Gartner Duct Cysts.

STUDY OBJECTIVE: Gartner duct cysts (GDCs) are rare embryological remnants of the mesonephric duct with the majority of cases discovered incidentally in asymptomatic patients. The largest prior published series evaluating the surgical management of GDCs included 4 patients. The present study aimed to determine the manifestations and outcomes of surgically managed patients with GDCs with important implications for surveillance, monitoring, and management. DESIGN: A retrospective chart review (Canadian Task Force classification III). SETTING: A tertiary care center. PATIENTS: All women diagnosed with GDCs from January 1994 to April 2014 at our institution were identified. Patients were included if they underwent surgical management and had GDCs confirmed by pathology. One hundred twenty-four charts were manually reviewed, and 29 patients were included in the analysis. INTERVENTIONS: All patients underwent surgical management, which included vaginal excision or marsupialization. MEASUREMENTS AND MAIN RESULTS: A total of 29 patients met the inclusion criteria for this study. The median age of the patients included in the analysis was 36 years old. Eleven patients were asymptomatic at the time of diagnosis (37.9%). The reason for surgical intervention was not available in 9 of these patients. Surgical intervention was performed in 2 of the 11 asymptomatic patients because of an increasing size of the lesion during observation. Presenting symptoms included dyspareunia or pain with tampon placement (37.9%), pelvic pain or pressure (24.1%), pelvic mass or bulge (17.2%), and urinary incontinence (6.9%). Preoperative imaging studies were obtained in 62% of patients; ultrasound was used in 44.4%, computed tomographic scanning in 22.2%, magnetic resonance imaging in 16.7%, and multiple modalities in 16.7%. Approximately 10% were found to have other genitourinary anomalies, including a bladder cyst, urethral diverticulum, and a solitary right kidney with uterine didelphis and septate vagina. The average cyst size was 3.5 cm (±1.8 cm). Surgical excision of GDCs was performed in all except for 3 cases of marsupialization. No intraoperative complications occurred. The median follow-up was 82 months (range, 0-246 months). One patient had possible recurrence with dyspareunia and protruding tissue diagnosed 14 months postoperatively. There were no other postoperative complications in the follow-up period. CONCLUSION: GDCs are rare pelvic masses that are often asymptomatic but may present with dyspareunia, pelvic pain or pressure, pelvic mass or bulge, or urinary symptoms. Excision or marsupialization is successful in the majority of cases without significant morbidity.

Correlation of Behavioral Interviewing Performance With Obstetrics and Gynecology Residency Applicant Characteristics☆?>.

OBJECTIVE: To determine which individual residency applicant characteristics were associated with improved performance on standardized behavioral interviews. Behavioral interviewing has become a common technique for assessing resident applicants. Few data exist on factors that predict success during the behavioral interview component of the residency application process. DESIGN: Interviewers were trained in behavioral interviewing techniques before each application season. Standardized questions were used. Behavioral interview scores and Electronic Residency Application Service data from residency applicants was collected prospectively for 3 years. SETTING: It included the Accreditation Council for Graduate Medical Education-accredited obstetrics-gynecology residency program at a Midwestern academic medical center. PARTICIPANTS: Medical students applying to a single obstetrics-gynecology residency program from 2012 to 2014 participated in the study. RESULTS: Data were collected from 104 applicants during 3 successive interview seasons. Applicant's age was associated with higher overall scores on questions about leadership, coping, and conflict management (for applicants aged ≤25, 26-27, or ≥28y, mean scores were 15.2, 16.0, and 17.2, respectively; p = 0.03), as was a history of employment before medical school (16.8 vs 15.5; p = 0.03). Applicants who participated in collegiate team sports scored lower on questions asking influence/persuasion, initiative, and relationship management compared with those who did not (mean, 15.5 vs 17.1; p = 0.02). CONCLUSIONS: Advanced applicant age and history of work experience before medical school may improve skills in dealing with difficult situations and offer opportunities in leadership. In the behavioral interview format, having relevant examples from life experience to share during the interviews may improve the quality of the applicant's responses. Increased awareness of the factors predicting interview performance helps inform the selection process and allows program directors to prioritize the most appropriate candidates for the match.
