RESUMO
Importance: Compared with early cord clamping (ECC), umbilical cord milking (UCM) reduces delivery room cardiorespiratory support, hypoxic-ischemic encephalopathy, and therapeutic hypothermia in nonvigorous near-term and full-term infants. However, UCM postdischarge outcomes are not known. Objective: To determine the 2-year outcomes of children randomized to UCM or ECC at birth in the Milking in Nonvigorous Infants (MINVI) trial. Design, Setting, and Participants: A secondary analysis to evaluate longer-term outcomes of a cluster-randomized crossover trial was conducted from January 9, 2021, to September 25, 2023. The primary trial took place in 10 medical centers in the US, Canada, and Poland from January 5, 2019, to June 1, 2021, and hypothesized that UCM would reduce admission to the neonatal intensive care unit compared with ECC; follow-up concluded September 26, 2023. The population included near-term and full-term infants aged 35 to 42 weeks' gestation at birth who were nonvigorous; families provided consent to complete developmental screening questionnaires through age 2 years. Intervention: UCM and ECC. Main Outcomes and Measures: Ages and Stages Questionnaire, 3rd Edition (ASQ-3) and Modified Checklist for Autism in Toddlers, Revised/Follow-Up (M-CHAT-R/F) questionnaires at ages 22 to 26 months. Intention-to-treat analysis and per-protocol analyses were used. Results: Among 1730 newborns from the primary trial, long-term outcomes were evaluated in 971 children (81%) who had ASQ-3 scores available at 2 years or died before age 2 years and 927 children (77%) who had M-CHAT-R/F scores or died before age 2 years. Maternal and neonatal characteristics by treatment group were similar, with median birth gestational age of 39 (IQR, 38-40) weeks in both groups; 224 infants (45%) in the UCM group and 201 (43%) in the ECC group were female. The median ASQ-3 total scores were similar (UCM: 255 [IQR, 225-280] vs ECC: 255 [IQR, 230-280]; P = .87), with no significant differences in the ASQ-3 subdomains. Medium- to high-risk M-CHAT-R/F scores were also similar (UCM, 9% [45 of 486] vs ECC, 8% [37 of 441]; P = .86). Conclusions and Relevance: In this secondary analysis of a randomized clinical trial among late near-term and full-term infants who were nonvigorous at birth, ASQ-3 scores at age 2 years were not significantly different between the UCM and ECC groups. Combined with previously reported important short-term benefits, this follow-up study suggests UCM is a feasible, no-cost intervention without longer-term neurodevelopmental risks of cord milking in nonvigorous near-term and term newborns. Trial Registration: ClinicalTrials.gov Identifier: NCT03631940.

OBJECTIVE: The primary objective of this clinical practice guideline is to provide gynaecologists with an algorithm and evidence to guide the diagnosis and management of endometrial polyps. TARGET POPULATION: All patients with symptomatic or asymptomatic endometrial polyps. OPTIONS: Options for management of endometrial polyps include expectant, medical, and surgical management. These will depend on symptoms, risks for malignancy, and patient choice. OUTCOMES: Outcomes include resolution of symptoms, histopathological diagnosis, and complete removal of the polyp. BENEFITS, HARMS, AND COSTS: The implementation of this guideline aims to benefit patients with symptomatic or asymptomatic endometrial polyps and provide physicians with an evidence-based approach toward diagnosis and management (including expectant, medical, and surgical management) of polyps. EVIDENCE: The following search terms were entered into PubMed/Medline and Cochrane: endometrial polyps, polyps, endometrial thickening, abnormal uterine bleeding, postmenopausal bleeding, endometrial hyperplasia, endometrial cancer, hormonal therapy, female infertility. All articles were included in the literature search up to 2021 and the following study types were included: randomized controlled trials, meta-analyses, systematic reviews, observational studies, and case reports. Additional publications were identified from the bibliographies of these articles. Only English-language articles were reviewed. VALIDATION METHODS: The authors rated the quality of evidence and strength of recommendations using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. See Appendix A (Tables A1 for definitions and A2 for interpretations of strong and weak recommendations). INTENDED AUDIENCE: Gynaecologists, family physicians, registered nurses, nurse practitioners, medical students, and residents and fellows. TWEETABLE ABSTRACT: Uterine polyps are common and can cause abnormal bleeding, infertility, or bleeding after menopause. If patients don't experience symptoms, treatment is often not necessary. Polyps can be treated with medication but often a surgery will be necessary. SUMMARY STATEMENTS: RECOMMENDATIONS.

BACKGROUND: Delayed cord clamping and umbilical cord milking provide placental transfusion to vigorous newborns. Delayed cord clamping in nonvigorous newborns may not be provided owing to a perceived need for immediate resuscitation. Umbilical cord milking is an alternative, as it can be performed more quickly than delayed cord clamping and may confer similar benefits. OBJECTIVE: We hypothesized that umbilical cord milking would reduce admission to the neonatal intensive care unit compared with early cord clamping in nonvigorous newborns born between 35 and 42 weeks' gestation. STUDY DESIGN: This was a pragmatic cluster-randomized crossover trial of infants born at 35 to 42 weeks' gestation in 10 medical centers in 3 countries between January 2019 and May 2021. The centers were randomized to umbilical cord milking or early cord clamping for approximately 1 year and then crossed over for an additional year or until the required number of consented subjects was reached. Waiver of consent as obtained in all centers to implement the intervention. Infants were eligible if nonvigorous at birth (poor tone, pale color, or lack of breathing in the first 15 seconds after birth) and were assigned to umbilical cord milking or early cord clamping according to their birth hospital randomization assignment. The baseline characteristics and outcomes were collected following deferred informed consent. The primary outcome was admission to the neonatal intensive care unit for predefined criteria. The main safety outcome was hypoxic-ischemic encephalopathy. Data were analyzed by the intention-to-treat concept. RESULTS: Among 16,234 screened newborns, 1780 were eligible (905 umbilical cord milking, 875 early cord clamping), and 1730 had primary outcome data for analysis (97% of eligible; 872 umbilical cord milking, 858 early cord clamping) either via informed consent (606 umbilical cord milking, 601 early cord clamping) or waiver of informed consent (266 umbilical cord milking, 257 early cord clamping). The difference in the frequency of neonatal intensive care unit admission using predefined criteria between the umbilical cord milking (23%) and early cord clamping (28%) groups did not reach statistical significance (modeled odds ratio, 0.69; 95% confidence interval, 0.41-1.14). Umbilical cord milking was associated with predefined secondary outcomes, including higher hemoglobin (modeled mean difference between umbilical cord milking and early cord clamping groups 0.68 g/dL, 95% confidence interval, 0.31-1.05), lower odds of abnormal 1-minute Apgar scores (Apgar ≤3, 30% vs 34%, crude odds ratio, 0.72; 95% confidence interval, 0.56-0.92); cardiorespiratory support at delivery (61% vs 71%, modeled odds ratio, 0.57; 95% confidence interval, 0.33-0.99), and therapeutic hypothermia (3% vs 4%, crude odds ratio, 0.57; 95% confidence interval, 0.33-0.99). Moderate-to-severe hypoxic-ischemic encephalopathy was significantly less common with umbilical cord milking (1% vs 3%, crude odds ratio, 0.48; 95% confidence interval, 0.24-0.96). No significant differences were observed for normal saline bolus, phototherapy, abnormal 5-minute Apgar scores (Apgar ≤6, 15.7% vs 18.8%, crude odds ratio, 0.81; 95% confidence interval, 0.62-1.06), or a serious adverse event composite of death before discharge. CONCLUSION: Among nonvigorous infants born at 35 to 42 weeks' gestation, umbilical cord milking did not reduce neonatal intensive care unit admission for predefined criteria. However, infants in the umbilical cord milking arm had higher hemoglobin, received less delivery room cardiorespiratory support, had a lower incidence of moderate-to-severe hypoxic-ischemic encephalopathy, and received less therapeutic hypothermia. These data may provide the first randomized controlled trial evidence that umbilical cord milking in nonvigorous infants is feasible, safe and, superior to early cord clamping.

Xenograft models are invaluable tools in establishing the current paradigms of hematopoiesis and leukemogenesis. The zebrafish has emerged as a robust alternative xenograft model but, like mice, lack specific cytokines that mimic the microenvironment found in human patients. To address this critical gap, we generated the first humanized zebrafish that express human hematopoietic-specific cytokines (GM-CSF, SCF, and SDF1α). Termed GSS fish, these zebrafish promote survival, self-renewal and multilineage differentiation of human hematopoietic stem and progenitor cells and result in enhanced proliferation and hematopoietic niche-specific homing of primary human leukemia cells. Using error-corrected RNA sequencing, we determined that patient-derived leukemias transplanted into GSS zebrafish exhibit broader clonal representation compared to transplants into control hosts. GSS zebrafish incorporating error-corrected RNA sequencing establish a new standard for zebrafish xenotransplantation that more accurately recapitulates the human context, providing a more representative cost-effective preclinical model system for evaluating personalized response-based treatment in leukemia and therapies to expand human hematopoietic stem and progenitor cells in the transplant setting.

BACKGROUND: Abnormal uterine bleeding (AUB) is the direct cause of a significant health care burden for women, their families, and society as a whole. Up to 30% of women will seek medical assistance for the problem during their reproductive years. OBJECTIVE: To provide current evidence-based guidelines on the techniques and technologies used in endometrial ablation (EA), a minimally invasive technique for the management of AUB of benign origin. METHODS: Members of the guideline committee were selected on the basis of individual expertise to represent a range of practical and academic experience in terms of both location in Canada and type of practice, as well as subspecialty expertise and general background in gynaecology. The committee reviewed all available evidence in the English medical literature, including published guidelines, and evaluated surgical and patient outcomes for the various EA techniques. Recommendations were established by consensus. EVIDENCE: Published literature was retrieved through searches of MEDLINE and The Cochrane Library in 2013 and 2014 using appropriate controlled vocabulary and key words (endometrial ablation, hysteroscopy, menorrhagia, heavy menstrual bleeding, AUB, hysterectomy). RESULTS were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies written in English from January 2000 to November 2014. Searches were updated on a regular basis and incorporated in the guideline to December 2014. Grey (unpublished) literature was identifies through searching the websites of health technology assessment and health technology-related agencies, clinical practice guideline collections, clinical trial registries, and national and international medical specialty societies. VALUES: The quality of evidence in this document was rated using the criteria described in the Report of the Canadian Task Force on Preventive Health Care (Table 1). RESULTS: This document reviews the evidence regarding the available techniques and technologies for EA, preoperative and postoperative care, operative set-up, anaesthesia, and practical considerations for practice. BENEFITS, HARMS, AND COSTS: Implementation of the guideline recommendations will improve the provision of EA as an effective treatment of AUB. Following these recommendations would allow the surgical procedure to be performed safely and maximize success for patients. CONCLUSIONS: EA is a safe and effective minimally invasive option for the treatment of AUB of benign etiology. Summary Statements 1. Endometrial ablation is a safe and effective minimally invasive surgical procedure that has become a well-established alternative to medical treatment or hysterectomy to treat abnormal uterine bleeding in select cases. (I) 2. Endometrial preparation can be used to facilitate resectoscopic endometrial ablation (EA) and can be considered for some non-resectoscopic techniques. For resectoscopic EA, preoperative endometrial thinning results in higher short-term amenorrhea rates, decreased irrigant fluid absorption, and shorter operative time than no treatment. (I) 3. Non-resectoscopic techniques are technically easier to perform than resectoscopic techniques, have shorter operative times, and allow the use of local rather than general anaesthesia. However, both techniques have comparable patient satisfaction and reduction of heavy menstrual bleeding. (I) 4. Both resectoscopic and non-resectoscopic endometrial ablation (EA) have low complication rates. Uterine perforation, fluid overload, hematometra, and cervical lacerations are more common with resectoscopic EA; perioperative nausea/vomiting, uterine cramping, and pain are more common with non-resectoscopic EA. (I) 5. All non-resectoscopic endometrial ablation devices available in Canada have demonstrated effectiveness in decreasing menstrual flow and result in high patient satisfaction. The choice of which device to use depends primarily on surgical judgement and the availability of resources. (I) 6. The use of local anaesthetic and blocks, oral analgesia, and conscious sedation allows for the provision of non-resectoscopic EA in lower resource-intense environments including regulated non-hospital settings. (II-2) 7. Low-risk patients with satisfactory pain tolerance are good candidates to undergo endometrial ablation in settings outside the operating room or in free-standing surgical centres. (II-2) 8. Both resectoscopic and non-resectoscopic endometrial ablation are relatively safe procedures with low complication rates. The complications perforation with potential injury to contiguous structures, hemorrhage, and infection. (II-2) 9. Combined hysteroscopic sterilization and endometrial ablation can be safe and efficacious while favouring a minimally invasive approach. (II-2) Recommendations 1. Preoperative assessment should be comprehensive to rule out any contraindication to endometrial ablation. (II-2A) 2. Patients should be counselled about the need for permanent contraception following endometrial ablation. (II-2B) 3. Recommended evaluations for abnormal uterine bleeding, including but not limited to endometrial sampling and an assessment of the uterine cavity, are necessary components of the preoperative assessment. (II-2B) 4. Clinicians should be vigilant for complications unique to resectoscopic endometrial ablation such as those related to fluid distention media and electrosurgical injuries. (III-A) 5. For resectoscopic endometrial ablation, a strict protocol should be followed for fluid monitoring and management to minimize the risk of complications of distension medium overload. (III-A) 6. If uterine perforation is suspected to have occurred during cervical dilatation or with the resectoscope (without electrosurgery), the procedure should be abandoned and the patient should be closely monitored for signs of intraperitoneal hemorrhage or visceral injury. If the perforation occurs with electrosurgery or if the mechanism of perforation is uncertain, abdominal exploration is warranted to obtain hemostasis and rule out visceral injury. (III-B) 7. With resectoscopic endometrial ablation, if uterine perforation has been ruled out acute hemorrhage may be managed by using intrauterine Foley balloon tamponade, injecting intracervical vasopressors, or administering rectal misoprostol. (III-B) 8. If repeat endometrial ablation (EA) is considered following non-resectoscopic or resectoscopic EA, it should be performed by a hysteroscopic surgeon with direct visualization of the cavity. Patients should be counselled about the increased risk of complications with repeat EA. (II-2A) 9. If significant intracavitary pathology is present, resectoscopic endometrial ablation combined with hysteroscopic myomectomy or polypectomy should be considered in a non-fertility sparing setting. (II-3A).
Contexte : Les saignements utérins anormaux (SUA) sont directement à l'origine d'un fardeau de santé considérable que doivent porter les femmes, leur famille et la société en général. Jusqu'à 30 % des femmes chercheront à obtenir l'aide d'un médecin pour contrer ce problème au cours de leurs années de fertilité. Objectif : Fournir des lignes directrices factuelles à jour quant aux techniques et aux technologies utilisées aux fins de l'ablation de l'endomètre (AE), soit une intervention à effraction minimale permettant la prise en charge des SUA d'origine bénigne. Méthodes : Les membres du comité sur la directive clinique ont été sélectionnés en fonction de leurs spécialisations respectives en vue de représenter une gamme d'expériences pratiques et universitaires : le milieu de pratique au Canada, le type de pratique, la sous-spécialité et les antécédents généraux en gynécologie ont donc été pris en considération. Le comité a analysé les données pertinentes issues de la littérature médicale anglophone (y compris les lignes directrices publiées), en plus d'évaluer les issues chirurgicales et les issues qu'ont connues les patientes à la suite de l'utilisation de diverses techniques d'AE. Les recommandations ont été formulées par consensus. Données : La littérature publiée a été récupérée par l'intermédiaire de recherches menées dans MEDLINE et The Cochrane Library en 2013 et en 2014 au moyen d'un vocabulaire contrôlé et de mots clés appropriés (p. ex. « endometrial ablation ¼, « hysteroscopy ¼, « menorrhagia ¼, « heavy menstrual bleeding ¼, « AUB ¼, « hysterectomy ¼). Les résultats ont été restreints aux analyses systématiques, aux études observationnelles et aux essais comparatifs randomisés / essais cliniques comparatifs publiés en anglais entre janvier 2000 et novembre 2014. Les recherches ont été mises à jour de façon régulière et intégrées à la directive clinique jusqu'en décembre 2014. La littérature grise (non publiée) a été identifiée par l'intermédiaire de recherches menées dans les sites Web d'organismes s'intéressant à l'évaluation des technologies dans le domaine de la santé et d'organismes connexes, dans des collections de directives cliniques, dans des registres d'essais cliniques et auprès de sociétés de spécialité médicale nationales et internationales. Valeurs : La qualité des résultats a été évaluée au moyen des critères décrits dans le rapport du Groupe d'étude canadien sur les soins de santé préventifs (Tableau). Résultats : Le présent document passe en revue les données quant aux techniques et aux technologies disponibles en ce qui concerne l'AE, les soins préopératoires et postopératoires, le milieu d'intervention, l'anesthésie et les facteurs pratiques à prendre en considération. Avantages, désavantages et coûts : La mise en Åuvre des recommandations de la présente directive clinique entraînera une amélioration de l'offre de l'AE à titre de traitement efficace contre les SUA. Le respect de ces recommandations permettrait l'exécution de l'intervention chirurgicale en cause de façon sûre et en maximiserait la réussite pour les patientes. Conclusions : L'AE est une option à effraction minimale sûre et efficace pour la prise en charge des SUA d'étiologie bénigne. Déclarations sommaires 1. L'ablation de l'endomètre est une intervention chirurgicale à effraction minimale sûre et efficace qui en est venue à constituer, dans certains cas, une solution de rechange bien établie au traitement médical ou à l'hystérectomie pour la prise en charge des saignements utérins anormaux. (I) 2. Une préparation de l'endomètre peut être mise en Åuvre pour en faciliter l'ablation résectoscopique et peut également être envisagée dans le cas de certaines techniques non résectoscopiques. Lorsque l'on a recours à l'ablation résectoscopique de l'endomètre, l'amincissement préopératoire de ce dernier donne lieu à une hausse des taux d'aménorrhée à court terme, à une atténuation de l'absorption du liquide de distension et à une réduction de la durée opératoire, par comparaison avec l'absence de traitement. (I) 3. Les techniques non résectoscopiques sont techniquement plus faciles à utiliser que les techniques résectoscopiques, nécessitent des temps opératoires plus courts et permettent l'utilisation d'une anesthésie locale (plutôt que d'avoir recours à une anesthésie générale). Toutefois, ces deux techniques comptent des taux comparables de satisfaction des patientes et d'atténuation des saignements menstruels abondants. (I) 4. Les techniques résectoscopiques et non résectoscopiques d'ablation de l'endomètre comptent toutes de faibles taux de complication. La perforation utérine, la surcharge liquidienne, l'hématomètre et les lacérations cervicales sont plus courantes dans le cas de l'AE résectoscopique; les crampes utérines, la douleur et les nausées / vomissements périopératoires sont plus courants dans le cas de l'AE non résectoscopique. (I) 5. L'efficacité de tous les dispositifs d'ablation non résectoscopique de l'endomètre disponibles au Canada a été démontrée en ce qui concerne l'atténuation du flux menstruel; de plus, ils mènent tous à des taux élevés de satisfaction des patientes. Le choix du dispositif à utiliser dépend principalement de l'opinion du chirurgien et de la disponibilité des ressources. (I) 6. L'utilisation d'anesthésiques et de blocs locaux, d'une analgésie orale et d'une sédation consciente permet la tenue d'une ablation non résectoscopique de l'endomètre au sein de milieux nécessitant des ressources moindres, y compris dans des milieux non hospitaliers réglementés. (II-2) 7. Les patientes n'étant exposées qu'à de faibles risques et présentant une tolérance satisfaisante à la douleur sont de bonnes candidates pour ce qui est de la tenue d'une ablation endométriale dans un milieu autre qu'en salle d'opération ou dans un centre chirurgical autonome. (II-2) 8. Les techniques d'ablation de l'endomètre tant résectoscopiques que non résectoscopiques sont relativement sûres et ne comptent que de faibles taux de complication. Parmi les complications les plus graves, on trouve la perforation (s'accompagnant de lésions potentielles aux structures adjacentes), l'hémorragie et l'infection. (II-2) 9. La tenue concomitante d'une stérilisation hystéroscopique et d'une ablation endométriale peut être sûre et efficace tout en favorisant une approche à effraction minimale. (II-2) Recommandations 1. L'évaluation préopératoire devrait être exhaustive, de façon à pouvoir écarter toute contre-indication à l'ablation de l'endomètre. (II-2A) 2. Les patientes devraient être avisées de la nécessité d'une contraception permanente à la suite de l'ablation de l'endomètre. (II-2B) 3. Les évaluations recommandées en présence de saignements utérins anormaux (dont, entre autres, le prélèvement endométrial et l'évaluation de la cavité utérine) sont des composantes nécessaires de l'évaluation préopératoire. (II-2B) 4. Les cliniciens devraient demeurer à l'affût des complications propres à l'ablation résectoscopique de l'endomètre, comme celles qui sont associées au produit de distension et aux lésions électrochirurgicales. (III-A) 5. Dans le cas de l'ablation résectoscopique de l'endomètre, un protocole strict devrait être respecté pour ce qui est de la surveillance liquidienne et de la prise en charge, et ce, afin de minimiser le risque de voir se manifester des complications associées à la surcharge de produit de distension. (III-A) 6. Lorsque l'on soupçonne qu'une perforation utérine s'est manifestée au cours de la dilatation cervicale ou dans le cadre de l'utilisation du résectoscope (sans électrochirurgie), l'intervention devrait être abandonnée et la patiente devrait faire l'objet d'une surveillance étroite de façon à ce que l'on puisse demeurer à l'affût des signes d'hémorragie intrapéritonéale ou de lésion viscérale. Lorsque la perforation se manifeste dans le cadre d'une électrochirurgie ou lorsque le mécanisme de la perforation demeure incertain, la tenue d'une exploration abdominale est justifiée pour assurer l'hémostase et écarter la présence de lésions viscérales. (III-B) 7. Dans le cas de l'AE résectoscopique, lorsque la présence d'une perforation utérine a été écartée, l'hémorragie aiguë pourrait être prise en charge au moyen d'un tamponnement intra-utérin par sonde de Foley, d'une injection intracervicale de vasopresseurs ou de l'administration de misoprostol par voie rectale. (III-B) 8. Lorsqu'une nouvelle ablation de l'endomètre est envisagée à la suite d'une intervention non résectoscopique ou résectoscopique, elle devrait être menée par un chirurgien hystéroscopique sous visualisation directe de la cavité. Les patientes devraient bénéficier de services de counseling au sujet des risques de complications qui sont associés à la tenue d'une nouvelle ablation de l'endomètre. (II-2A) 9. En présence d'une pathologie intracavitaire considérable, la tenue concomitante d'une ablation résectoscopique de l'endomètre et d'une myomectomie / polypectomie hystéroscopique devrait être envisagée. (II-3A).

INTRODUCTION AND HYPOTHESIS: Little evidence is available concerning the ability of women with urinary incontinence (UI) to properly assess their problem. This study compared women's assessments of their UI type with physicians' diagnoses. METHODS: Women referred to a urogynecology clinic for UI were asked to anonymously answer a short validated Questionnaire for Urinary Incontinence Diagnosis (QUID) before their physician visit. Women completed the QUID and read a brief explanation of its interpretation, after which they were asked to choose their UI type: stress, urge, or mixed. Physicians, blinded to patients' answers, conducted routine examinations and indicated their diagnoses of incontinence types. Sample size was representative of typical clinic volumes. Levels of agreement among physician diagnoses, QUID scores, and patient self-assessments of UI type were calculated with kappa (κ) statistics. Physician diagnosis was the gold standard. RESULTS: We had 497 patients return the questionnaire; 338 met inclusion criteria. Mean age was 53 (± 13) years. Levels of agreement among physician diagnoses and patients' assessments of UI type (κ=0.411, p<0.01) and QUID scores (κ=0.378, p<0.01) were significant. Significant level of agreement was found among QUID scores and patients' assessments of UI type (κ=0.497, p<0.001). CONCLUSIONS: With aid of a brief standardized questionnaire, women can accurately assess their UI type. This suggests women could be educated about UI via good-quality Internet health sites and choose appropriate conservative management options.

OBJECTIVES: To review the etiology and incidence of and associative factors in the formation of adhesions following gynaecological surgery. To review evidence for the use of available means of adhesion prevention following gynaecological surgery. OPTIONS: Women undergoing pelvic surgery are at risk of developing abdominal and/or pelvic adhesive disease postoperatively. Surgical technique and commercial adhesion prevention systems may decrease the risk of postoperative adhesion formation. OUTCOMES: The outcomes measured are the incidence of postoperative adhesions, complications related to the formation of adhesions, and further intervention relative to adhesive disease. EVIDENCE: Medline, EMBASE, and The Cochrane Library were searched for articles published in English from 1990 to March 2009, using appropriate controlled vocabulary and key words. Results were restricted to systematic reviews, randomized control trials/controlled clinical trials, cohort studies, and meta-analyses specifically addressing postoperative adhesions, adhesion prevention, and adhesive barriers. Searches were updated on a regular basis and incorporated in the guideline to March 2009. Grey (unpublished) literature was identified through searching the websites of health technology assessment and health technology assessment-related agencies, clinical practice guideline collections, clinical trial registries, and national and international medical specialty societies. VALUES: The quality of evidence was rated using the criteria described in the Report of the Canadian Task Force on Preventive Health Care.

OBJECTIVE: To formulate clinical recommendations for the assessment of endometrial thickening when it is found on ultrasound in a postmenopausal patient without bleeding. OUTCOMES: Ensure that women with asymptomatic thickening and endometrial polyps found on ultrasound are managed appropriately. EVIDENCE: Published literature was retrieved through searches of English language articles from the EMBASE, Cochrane, and PubMed databases for relevant peer-reviewed articles dating from 1970 to 2009, using appropriate controlled vocabulary (e.g., "asymptomatic endometrial thickness," "endometrial cancer," "postmenopausal bleeding," "transvaginal ultrasonography," "endometrial biopsy" and "endometrial polyp"). Results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies. Searches were updated on a regular basis and incorporated in the guideline to April 2010. Grey (unpublished) literature was identified through searching the websites of health technology assessment and health technology assessment-related agencies, clinical practice guideline collections, clinical trial registries, and national and international medical specialty societies. VALUES: The level of evidence was determined according to the criteria established by the Canadian Task Force on Preventative Health Care (Table). Recommendations are ranked according to this method. BENEFITS, HARMS, AND COSTS: It is anticipated that the adoption of these recommendations would save postmenopausal women unnecessary anxiety, pain, and risk of procedural complication. It is also expected to decrease the cost to the health system by eliminating unnecessary interventions.

OBJECTIVE: To assess the perceived learning outcomes from the various roles involved in the development and implementation of an objective structured clinical examination (OSCE) by residents for residents. METHODS: Final-year residents in Obstetrics and Gynaecology at the University of Toronto created OSCE stations in preparation for their certification examination. They evaluated their experience using a survey designed to assess the learning effectiveness of the roles played in an OSCE. Residents were asked to compare resident-created stations with faculty-created stations. RESULTS: The students found every aspect of OSCE development to be of educational benefit. Residents rated the candidate role as more beneficial than other roles. Residents perceived the benefits of the OSCE sessions to be greater than equivalent lengths of time spent in traditional group study sessions. CONCLUSIONS: A self-directed learning approach, based on OSCE development and implementation, shows promise as a learning aid at the senior residency level. We suggest a controlled trial designed to objectively measure outcomes of this learner-centred approach.
