Background: Mammalian orthoreovirus type 3 (MRV3), which is responsible for gastroenteritis in many mammalian species including pigs, has been isolated from piglets with severe diarrhea. However, the use of pig-derived cells as an infection model for swineMRV3 has rarely been studied. Objectives: This study aims to establish porcine intestinal organoids (PIOs) and examine their susceptibility as an in vitro model for intestinal MRV3 infection. Methods: PIOs were isolated and established from the jejunum of a miniature pig.Established PIOs were characterized using polymerase chain reaction (PCR) and immunofluorescence assays (IFAs) to confirm the expression of small intestine-specific genes and proteins, such as Lgr5, LYZI, Mucin-2, ChgA, and Villin. The monolayered PIOs and threedimensional (3D) PIOs, obtained through their distribution to expose the apical surface, were infected with MRV3 for 2 h, washed with Dulbecco’s phosphate-buffered saline, and observed. Viral infection was confirmed using PCR and IFA. We performed quantitative realtime reverse transcription-PCR to assess changes in viral copy numbers and gene expressions linked to intestinal epithelial genes and antiviral activity. Results: The established PIOs have molecular characteristics of intestinal organoids. Infected PIOs showed delayed proliferation with disruption of structures. In addition, infection with MRV3 altered the gene expression linked to intestinal epithelial cells and antiviral activity, and these effects were observed in both 2D and 3D models. Furthermore, viral copy numbers in the supernatant of both models increased in a time-dependent manner. Conclusions We suggest that PIOs can be an in vitro model to study the infection mechanism of MRV3 in detail, facilitating pharmaceutical development.

Background: This study was conducted to examine the effect of adverse childhood experiences on depressive symptoms in university students and to verify whether positive psychological resources act as a protective factor for depression. Methods: Data from 1,317 young adults aged 18-29 years who took part in the university-based cross-sectional survey were analyzed. All participants completed self-report questionnaires that included demographic variables, the Adverse Childhood Experience (ACE) Scale, the Patient Health Questionnaire-9, and the Positive Resources Test. Results: The incidence of depression was 33.3% and was higher in women than in men. Based on the 10 ACE categories, 32.7% of the students reported one or more adverse childhood experiences, and 14.4% reported two or more forms of adverse childhood experiences. Students with depressive symptoms were likely to report more traumatic experiences in childhood and fewer positive psychological resources than those without depressive symptoms. Hierarchical regression analysis indicated that positive psychological resources moderated the relationship between adverse childhood experiences and depression. Conclusion Based on these results, professionals should consider identifying adverse childhood experiences early and provide active mental health service support, including positive psychological and social resources for individuals who have adverse experiences during childhood.

Meckel diverticulum is a common congenital malformation of the gastrointestinal tract and can cause complications such as ulceration, hemorrhage, intussusception, and perforation. This report describes a very rare complication of an enterovesical fistula associated with chronic Meckel diverticulum. A 51-year-old male presented with over 10 years of persistent pyuria. Tests were performed to rule out malignancy, including serum prostate-specific antigen level, urine cytology, bacterial culture, cystoscopy, and bladder computed tomography. An enterovesical fistula was identified, and laparoscopic exploration was performed. The findings suggested enterovesical fistula formation caused by chronic inflammation at the tip of a Meckel diverticulum. Segmental resection of the small bowel including the diverticulum and primary repair of the urinary bladder along with partial cystectomy were performed. The postoperative clinical course was uneventful. An enterovesical fistula is a very rare complication resulting from chronic inflammation of a Meckel diverticulum.

Objectives: Adverse childhood experiences (ACEs) of mothers may negatively affect the mental health of their offspring. Little is known about the intergenerational effect of maternal ACE on post-traumatic stress disorder (PTSD) in the offspring. This study investigated the impact of maternal ACEs on PTSD in the offspring. Methods: A total of 156 mothers with children aged 13–18 years completed the Diagnostic Interview Schedule for Children (DISC) Predictive Scales to determine the presence of psychiatric disorders in their offspring. The subjects completed the ACE questionnaire and the Early Trauma Inventory Self-Report-Short Form. Multivariable logistic regression was used to analyze the relationship between maternal ACEs and PTSD in the offspring. Results: Of the mothers, 23.7% had at least one ACE, and PTSD was reported in 21.8% of the offspring. The offspring of the mothers in the ACE group had a significantly higher rates of traumatic experiences and PTSD than the offspring of the mothers in the no ACE group. Maternal household dysfunction independently predicted offspring PTSD [odds ratio (OR)=3.008, p=0.05), and three or more maternal ACEs were significantly related to PTSD in the offspring (OR=10.613, p=0.025). Conclusion Maternal ACEs have a significant impact on the risk of traumatic experiences and PTSD in the offspring. These findings suggest the presence of intergenerational transmissions by which maternal ACEs affect the mental health of the offspring.

BACKGROUND: Social anxiety and suicide are serious common problems in college students. However, there are few studies on the relationship between social anxiety symptoms and suicidal risk. Therefore, we evaluated the associationbetween social anxiety symptoms and suicidal risk in college students.METHODS: A total of 579 college students were recruited for a college-based cross-sectional survey in the Jeju area. The participants completed a questionnaire gathering sociodemographic information; they also completed the Korean Social Avoidance and Distress Scale (SADS) to assess social anxiety symptoms and the Center for Epidemiologic Studies Depression Scale (CES-D) to assess depressive symptoms. To obtain information regarding suicidal risk, we administered the Korean version of the Suicide module of the Mini International Neuropsychiatric Interview (M.I.N.I.).RESULTS: The prevalence of higher levels of social anxiety symptoms among college students was 28.0% (n=162). A higher level of social anxiety symptoms resulted in a 2.10-times higher suicidal risk after adjusting for depression in college students (95% confidence interval, 1.05-4.23; p=0.037).CONCLUSION: Based on the results of this study, social anxiety symptoms should be managed and controlled to prevent suicidality in Korean college students.

β Blockers such as propranolol and labetalol are known to induce toxic myopathy because of their partial β₂ adrenoceptor agonistic effect. Nebivolol has the highest β1 receptor affinity among β blockers, and it has never been reported to induce rhabdomyolysis until now. We report a patient who developed rhabdomyolysis after changing medication to nebivolol. A 75-year-old woman was admitted to our hospital because of generalized weakness originating 2 weeks before visiting. Approximately 1 month before her admission, her medication was changed from carvedilol 12.5 mg to nebivolol 5 mg. Over this time span, she had no other lifestyle changes causing rhabdomyolysis. Her blood chemistry and whole body bone scan indicated rhabdomyolysis. We considered newly prescribed nebivolol as a causal agent. She was prescribed carvedilol 12.5 mg, which she was previously taking, instead of nebivolol. She was treated by hydration and urine alkalization. She had fully recovered and was discharged.

PURPOSE: The goal of this study was to assess the clinicopathologic and ultrasonographic features of thyroid nodules with nondiagnostic results on repeat ultrasonography (US)-guided fineneedle aspiration biopsy (FNAB) according to size and the number of suspicious findings and to determine the proper management of nodules with consecutive nondiagnostic results. METHODS: This retrospective study included 297 nodules with nondiagnostic results on repeat FNAB that were evaluated by US over the course of at least 12 months of follow-up, a follow-up biopsy, or an operation. We compared clinical and US variables between benign and malignant nodules in thyroid nodules with repeat nondiagnostic results. RESULTS: The comparison of benign and malignant nodules with repeat nondiagnostic results revealed that age, marked hypoechogenicity, irregular or microlobulated margins, microcalcifications, and nonparallel shape were significantly associated with malignancy. Multivariate logistic regression analysis in malignant nodules revealed that microcalcifications and irregular or microlobulated margins were independently associated with malignancy. Among them, only irregular or microlobulated margins were independently significant as a predictor of malignancy in repeatedly nondiagnostic nodules measuring >10 mm. Using receiver operating characteristic analysis, the best cutoff value for the "number of suspicious findings" between benign and malignant nodules was three in nodules of all sizes, three in nodules measuring ≤10 mm, and two in nodules measuring >10 mm. CONCLUSION: Irregular or microlobulated margins may be the most frequent US features in repeatedly nondiagnostic nodules >10 mm. The presence of "two or more suspicious findings" can be used as the cutoff for distinguishing benign and malignant nodules.

PURPOSE: The aim of this study was to investigate the change of nutritional status and the incidence of dumping syndrome after gastrectomy for gastric cancer. METHODS: From January 2013 to May 2014, 36 patients who underwent gastrectomy for gastric cancer were prospectively investigated in terms of nutritional status by body weight, anthropometric measurements, biochemical data, and Patient-Generated Subjective Global Assessment (PG-SGA). Dumping syndrome was assessed using a newly developed questionnaire based on the Japanese Society of Gastroenterological Surgery survey and Sigstad's scoring system. RESULTS: Body weight losses were 4.6%, 8.1%, and 6.9% at discharge, six months, and one year after discharge, respectively. Triceps skinfold thickness had no significance, however, mid-arm muscle circumference showed significant loss after gastrectomy. A part of the biochemical data showed significant change after gastrectomy, but almost indicated a restoring tendency within two months after discharge. In terms of PG-SGA, 33 patients (91.7%) were classified as A (well-nourished) before surgery, however, the number of well-nourished patients showed a sharp decrease to 1 (2.8%) at two weeks after discharge, and then gradually increased to 25 (69.4%) at one year. The main obstacles against diet intake were reported as 'early satiety' and 'anxiety'. The number of patients who had experience in at least one dumping syndrome related symptom was 21 (58.3%) at discharge, 26 (72.2%) at two months after discharge, and 11 (30.6%) at one year after discharge. CONCLUSION: Nutritional deficit as well as dumping syndrome is encountered in a large number of gastric cancer patients after gastrectomy. Postoperative nutritional support and personalized education seem to be very important during the postoperative period.
