Effects of Perceived Parent-Child Relationships and Self-Concept on Creative Personality among Middle School Students.

This study investigated the impact of perceived parent-child relationships on creative personality in middle school students according to self-concept, focusing on environmental (parent-child relationships) and individual (self-concept) factors that can influence these students' creative personalities. To this end, this study verified the moderation effect using sixth-year data (third year of middle school students) from the Seoul Longitudinal Educational Study 2010 Panel, utilizing SPSS 26.0 and the PROCESS macro. The results revealed that the self-concept of middle school students moderated the influence of parent-child relationships on creative personality. Specifically, it was found that as the level of self-concept increased above the average the positive relationship between parent-child relationships and creative personality strengthened. Based on the study's findings, theoretical and practical suggestions for creating a home and educational environment to promote creativity during adolescence were discussed.

A longitudinal study of the effect of individual and socio-cultural factors on students' creativity.

This longitudinal study investigated how characteristics of individual and social relationships affect Korean students' creativity development. Fifth graders (male: 3,623, female: 3,701) from 242 schools in Korea were followed annually from their 5th to 9th grades (indicating from the 5th elementary school grade to the 3rd middle school grade in the Korean school system). Exploratory factor analysis, internal consistency reliability (coefficient alpha), confirmatory factor analysis, and two-level growth model methods were performed. We investigated all nine constructs and their related items by checking metric and scalar invariance assumptions. When the measurement invariance assumptions were satisfied, we used the mean of items that constitute respective factors. We checked growth trajectories of creativity and tapped the possibility of the existence of subgroups based on the growth/change pattern using latent class growth modeling. The results showed that no subgroups existed. Thus, we constructed a two-level growth model to investigate the overall growth pattern of the students. Regarding level 1, we included time-varying variables such as peer attachment, self-regulation habits (self-management), parents' academy-oriented involvement, parent affective support, individualized, interactive teaching methods, teachers' academic pressure, and academic achievement. At level 2, we used gender and parenting style that was obtained at time point 1. The final combined model incorporating level 1 and 2 variables showed that students' self-regulation had the most association with the student's creativity followed by peer attachment, parents' academic support, interaction with parents, interaction with teachers, academic pressure from teachers, and relationships with teachers. Methods for enhancing students' creativity were discussed.

[Portal Biliopathy Misdiagnosed as Hilar Cholangiocarcinoma].

Portal biliopathy refers to the changes in the bile duct caused by portal vein thrombosis or obstruction. It is assumed to be caused by cavernous transformation due to the development of the venous system surrounding the bile duct, but the exact pathology is still unknown. Biliary morphologic abnormalities of portal biliopathy are discovered incidentally on radiographic images, but it is sometimes difficult to differentiate them from cholangiocarcinoma. Given the poor prognosis of cholangiocarcinoma, a surgical approach can be considered when the diagnosis is uncertain. Herein, we report a case of portal biliopathy with bile ductal wall thickening, which was diagnosed after surgical resection was performed due to the presumed diagnosis of cholangiocarcinoma.

Discrete terminal ileal ulcers in patients diagnosed with ulcerative colitis: clinical significance and natural course.

BACKGROUND: Terminal ileal (TI) ulcers are occasionally detected in asymptomatic individuals and mostly resolve without any treatment. In patients with ulcerative colitis (UC), TI ulcers are infrequently observed without evidence of backwash ileitis. However, the clinical significance and natural course of the lesions are unclear. The aim of our study was to evaluate the frequency and clinical implications of TI ulcers in patients with UC. METHODS: We retrospectively reviewed 397 patients with UC via successful TI intubation during colonoscopy. We compared the clinical characteristics of patients manifesting TI ulcers with those who did not. The natural course of TI lesions was also investigated during the follow-up periods. RESULTS: Forty-one patients (10.3%) showed TI ulcers without evidence of inflammation in the right colon. The patients with and without TI ulcers were not different in terms of baseline characteristics, disease activity and extent at the time of the UC diagnosis, proximal extension, Mayo endoscopic score at the last endoscopic examination, medication history, UC-related hospitalization, and relapse during follow-up periods. Of the 30 patients who underwent follow-up colonoscopy in patients with TI ulcers, 23 (76.7%) showed resolution of TI ulcer. In addition, patients with remaining TI ulcers did not differ in disease activity and biopsy results compared with those with resolving TI ulcers. CONCLUSIONS: Discrete TI ulcers are more common in patients with UC, compared with the healthy cohort. No significant clinical impact on disease extension and severity is found.

Relationship between angiography timing and angiographic visualization of extravasation in patients with acute non-variceal gastrointestinal bleeding.

BACKGROUND: Angiographic embolization is now considered the first-line therapy for acute gastrointestinal (GI) bleeding refractory to endoscopic therapy. The success of angiographic embolization depends on the detection of the bleeding site. This study aimed to identify the clinical and procedural predictors for the angiographic visualization of extravasation, including angiography timing, as well as analyze the outcomes of angiographic embolization according to the angiographic visualization of extravasation. METHODS: The clinical and procedural data of 138 consecutive patients (mean age, 66.5 years; 65.9% men) who underwent angiography with or without embolization for acute non-variceal GI bleeding between February 2008 and July 2018 were retrospectively analyzed. RESULTS: Of the 138 patients, 58 (42%) had active extravasation on initial angiography and 113 (81.9%) underwent embolization. The angiographic visualization of extravasation was significantly higher in patients with diabetes (p = 0.036), a low platelet count (p = 0.048), high maximum heart rate (p = 0.002) and AIMS65 score (p = 0.026), upper GI bleeding (p = 0.025), and short time-to-angiography (p = 0.031). The angiographic embolization was successful in all angiograms, with angiographic visualization of extravasation (100%). The clinical success of patients without angiographic visualization of extravasation (83.9%) was significantly higher than that of patients with angiographic visualization of extravasation (65.5%) (p = 0.004). In multivariate analysis, the time-to-angiography (odds ratio 0.373 [95% CI 0.154-0.903], p = 0.029) was the only significant predictor associated with the angiographic visualization of extravasation. The cutoff value of time-to-angiography was 5.0 h, with a sensitivity and specificity of 79.3% and 47.5%, respectively (p = 0.012). CONCLUSIONS: Angiography timing is an important factor that is associated with the angiographic visualization of extravasation in patients with acute GI bleeding. Angiography should be performed early in the course of bleeding in critically ill patients.
