Purpose: To analyze the leadership network structure among nursing leaders in Spain identified through the Grupo40Enfermeras y Universidad event. Methods: A descriptive cross-sectional study using social network analysis was used. Study sample consisted of 210 individuals, of whom 119 received nominations as referents. Structural analysis of the network was conducted using centrality and cohesion. Results: A network structure was generated in which different leadership strategies were identified through InDegree, Eigenvector, and Betweenness Centrality. Five leaders were identified as bridges to other individuals using Betweenness. The whole network presented little cohesion although two highly cohesive cores were detected by K-core measurements. Conclusion: A strategy is needed to support nursing leaders with high degree of Betweenness to serve as bridges to connect other nursing leaders

ObjectiveIn this video, we present our technique for ureter assessment during pelvic ultrasound examination. MethodsWe used a general electric Voluson E10 (General electric, Wauwatosa, WI, USA) to perform transvaginal ultrasonography. These images were shared after thorough counselling, and obtaining informed consent from the patient. Thisvideo was edited using FinalCut ProX® (Apple Inc, Cupertino, CA, USA). ResultsWe systematized this routine after assessing the cervix, uterus, and adnexa. The vaginal probe was slightly removed tofocus on the urethra. Next, we approached the hand on the contralateral thigh to the ureter. At this point, the probewas directed to the lateral pelvic wall where the ureteric orifice was found. Then, we raised our hands and performan internal rotation movement to ascend the ureteral segments until it is related to the iliac vessels. ConclusionThe urinary tract may be involved in gynecological pathologies. Transvaginal ultrasound is an easy, reproducible, andwell-tolerated examination that can be used to evaluate the ureters below the pelvic brim. 영어

Objectives: The upper molars generally have three roots; therefore, different combinations of fusion can occur, increasing the possibility of finding more complex root canal systems. The purpose of this study was to evaluate the prevalence and characterization of fused roots in first and second maxillary molars using cone-beam computed tomography (CBCT) in a Colombian population. Materials and Methods: A total of 1274 teeth were evaluated, of which 534 were maxillary first molars and 740 were maxillary second molars. Axial sections were made at the cervical, middle, and apical levels to determine the prevalence of root fusion and the types of fusion. Results: Overall, 43% of the molars (n = 551) presented some type of fused root. Root fusion was present in 23.4% of the maxillary first molars. The most frequent type of fused root was type 3 (distobuccal-palatal; DB-P) (58.9%). Root fusion was observed in 57.6% of the maxillary second molars, and the most prevalent type of fused root was type 6 (cone-shaped) (45.2%). Of the maxillary molars, 12.5% were classified as C-shaped. Conclusion: Within the limitations of this study, there was a high prevalence of fused roots in maxillary molars in the Colombian population, mainly in the maxillary second molars. In first molars, the most common type of fused root was type 3 (DB-P) and in second molars, the most common type was type 6 (cone-shaped). Additionally, molars with root fusion presented variation at different levels of the radicular portion, with implications for treatment quality.

Objective: Patients with endometriosis are at increased risk of ovarian cancer. It has been suggested that atypical endometriosis is a precursor lesion of endometriosis-associated ovarian cancer (EAOC). The aim of this study is to evaluate if cytologic (cellular) atypia and architectural atypia (hyperplasia), histologic findings described as atypical endometriosis, play a different role in patients with EAOC. Methods: A prospective study was conducted between January 2014 and April 2017 at our institution with patients undergoing surgery with a histologic diagnosis of endometriosis, ovarian cancer, or EAOC. The prevalence and immunohistologic study (Ki-67, BAF250a, COX-2) of cases of cellular and architectural atypia in endometriosis were analyzed. Results: Two hundred and sixty-six patients were included: the diagnosis was endometriosis alone in 159 cases, ovarian cancer in 81, and EAOC in 26. Atypical endometriosis was reported in 23 cases (12.43%), 39.13% of them found in patients with EAOC. Endometriosis with cellular atypia was found mainly in patients without neoplasm (71.4%), and endometriosis with architectural atypia was seen in patients with ovarian cancer (88.9%) (p=0.009). Ki-67 was significantly higher in endometriosis patients with architectural atypia than those with cellular atypia. Conclusion: The diagnosis of endometriosis with architectural atypia is important because it may be a precursor lesion of ovarian cancer; therefore, pathologists finding endometriosis should carefully examine the surgical specimen to identify any patients with hyperplasia-type endometriosis, as they may be at higher risk of developing EAOC.
