Comparison of laxative effects of fermented soybeans (Cheonggukjang) containing toxins and biogenic amines against loperamide-induced constipation mouse model

BACKGROUND/OBJECTIVES@#(Cheonggukjang) is a traditional fermented soybean paste with significant health-promoting effects. On the other hand, there have been insufficient studies on the safety and efficacy of (Cheonggukjang), which is produced using traditional methods containing toxins and biogenic amines (BAs). This study compared the laxative effect of (Cheonggukjang), containing high or low levels of toxins and BAs (HTBC or LTBC) in a loperamide (Lop)-induced constipation mouse model.MATERIALS/METHODS: To induce constipation, Lop (5 mg/kg) was administered orally to ICR mice twice a day for 4 days, and the dose was increased to 8 mg/kg after a 3-day rest period. (Cheonggukjang) (500 mg/kg, HTBC, or LTBC respectively) was administered for four weeks before the Lop treatment. @*RESULTS@#The number of stools, fecal weight, water contents, gastrointestinal transit, and histological alterations were recovered significantly in the HTBC or LTBC groups. HTBC and LTBC administration did not induce significant changes in body weight, dietary intake, and behavior. The opioid-receptor downstream signaling pathway in colon tissues was also evaluated. The c-Kit, stem cell kinase, and mitogen-activated protein kinases subfamilies, including extracellular signal-regulated kinase 1/2, c-Jun N-terminal kinases, and p38, were all downregulated in the HTBC or LTBC-administered mice colon compared to the Lop group. @*CONCLUSION@#These results show that (Cheonggukjang), containing high levels of toxins and BAs, have a similar laxative effect in a mouse model of Lop-induced constipation.

A Comparative Study on the Nursing Dependency of Suspected COVID-19 Patients and General Patients in the Emergency Department / 임상간호연구

Purpose@#This study was conducted to investigate the nursing needs and workload of nurses according to nursing dependency for effective placement of nursing staff in the emergency department (ED). @*Methods@#In June 2020, 256 adult patients who visited the ED were classified as two groups, suspected COVID-19 patients and general patients. The participants’electronic medical records were analyzed using descriptive statistics, t-test, x 2 -test, and Fisher's exact test using the SPSS. @*Results@#The patient dependence score showed a significant difference between the two groups, with an average of 13.99±1.85 for the suspected COVID-19 patient group and 10.58±2.10 for the general patient group (t=12.42, p<.001). There were statistically significant differences in communication (t=3.28, p=.001), mobility (t=3.29, p=.001), nutrition, elimination, and personal care (t=7.34, p<.001) among the six domains of nursing dependency. In the domains of environment, safety, health, and social needs, the dependency score was 3 for all suspected COVID-19 patients and 1 for all general patients. @*Conclusion@#The results of this study confirmed that infection control activities of emergency patients who need isolation affect the patients’ nursing dependency on nursing care.

Semantic Network Analysis of Iussues Related to Mental Illness in Korea Media: Focusing on the Five Major Media from 2016 to 2018 / 신경정신의학

OBJECTIVES: This study examined the trend of press reports on mental illness in Korea to help set a desirable direction for future press reports on the subject.METHODS: This study adopted the method of semantic network analysis to analyze the trend of press reporting on mental illness in Korea. The study analyzed 1253 newspaper articles from 2016 to 2018 published by the five major Korean press: The Kyunghyang Shinmun, The Dong-A Ilbo, The Chosun Ilbo, The JoongAng Ilbo, and The Hankyoreh.RESULTS: The number of articles on mental illness is on the decline year by year, with 465 articles in 2016, 406 in 2017, and 382 in 2018. According to keyword analysis, the order of the words of the highest frequency is as follows: treatment (659), patients (486), mental health (466), incidents (436), and children and adolescents (413). In terms of the Degree Centrality, Closeness Centrality, and Betweenness Centrality, the following words are commonly ranked within the top 10 on the lists: treatment, children and adolescents, patient, mental health, depressive disorder, family, suicide, and counselling.CONCLUSION: The press should pay more attention to mental illness, and its reporting should guarantee accuracy, objectivity, fairness, diversity, and social responsibility. In addition, reports on mental illness need to provide balanced health information, considering the readers, from basic information on mental illness to detailed treatment methods. Establishing reporting guidelines for mental illness would help reduce harm and prejudice related to mental illness and increase access to treatment.

Comparison of Attention-Deficit/Hyperactivity Disorder Practice in Adults According to a Training Background in Child Psychiatry

OBJECTIVES: Awareness of attention-deficit/hyperactivity disorder (ADHD) in adults has significantly increased; however, clinical data specific to the Korean population are insufficient. Clinical experience of ADHD may differ based on whether psychiatrists have received pediatric psychiatry-specific training. In order to prepare a practice parameter for adult ADHD patients in Korea, we examined questionnaire data to observe how pediatric psychiatry training could affect clinical practice for adults with ADHD. METHODS: A questionnaire about the diagnosis and treatment process was distributed to both general psychiatrists (GPsy) and child and adolescent psychiatrists (CAP) at the summer and winter workshop meetings of Korean Academy of Child and Adolescent Psychiatry. RESULTS: In total, 142 psychiatrists participated in the survey (86 GPsy, 56 CAP). GPsy and CAP preferred pharmacotherapy (GPsy 82.40%, CAP 64.30%) as the primary treatment option and answered that the clinical psychiatric interview is the most necessary step in diagnostic assessment (GPsy 22.16%, CAP 19.00%). The GPsy responded with an optimal and average treatment duration that was shorter than that reported by CAP. CONCLUSION: Identification of the initial presenting symptom as the correct diagnosis and the optimal duration of pharmacotherapy differed between GPsy and CAP in practice, whereas concepts in diagnosis and treatment of ADHD in adults were similar for both groups. These results suggest the urgent need for the Continuing Medical Education program for psychiatrists treating adults with ADHD.

The Revised Korean Practice Parameter for the Treatment of Attention-Deficit Hyperactivity Disorder (II): Diagnosis and Assessment

Attention-deficit hyperactivity disorder (ADHD) is a highly prevalent, impairing, and comorbid disorder that persists into adulthood. ADHD should be diagnosed in the same manner as other common adult mental health disorders. The three most important components in the comprehensive evaluation of patients with ADHD are the clinical interview, medical examination, and completion and scoring of behavior rating scales. The diagnostic evaluation of ADHD should include questions about the symptoms, family history, prior evaluation and treatment of ADHD, as well as other problems including alcohol and drug use. Screening interviews or rating scales, as well as interviews, should be used. When it is feasible, clinicians may wish to supplement these components of the evaluation with the objective assessments of the ADHD symptoms, such as through psychological tests. These tests are not essential to reaching a diagnosis, however, or to treatment planning, but may yield further information about the presence and severity of cognitive impairments that could be associated with some cases of ADHD. As comorbidity is the rule rather than the exception, clinicians should carefully screen for comorbid disorders as part of a comprehensive assessment of ADHD. To receive a diagnosis of ADHD, the person must be experiencing significant distress or impairment in his or her daily functioning, and must not meet the criteria for other mental disorders which might better account for the observed symptoms, such as mental retardation, autism or other pervasive developmental disorders, mood disorders and anxiety disorders. This report aims to suggest practice guidelines for the assessment and diagnosis of children, adolescents and adults with ADHD in Korea.

Low serum bilirubin level predicts the development of chronic kidney disease in patients with type 2 diabetes mellitus

BACKGROUND/AIMS: We evaluated whether serum bilirubin levels can predict the development of chronic kidney disease (CKD) in patients with type 2 diabetes mellitus (T2DM). METHODS: This was a retrospective observational longitudinal study of patients presenting at the Pusan National University Hospital. A total of 349 patients with T2DM and preserved kidney function (estimated glomerular filtration rate ≥ 60 mL/min/1.73 m²) were enrolled. The main outcome was the development of CKD stage 3 or greater. The patients were divided into four groups according to the quartiles of the total serum bilirubin levels at baseline. RESULTS: The group with the lowest range of total serum bilirubin level (Q1) showed the highest cumulative incidence of CKD stage 3 or greater than that of the other lower quartiles (Q1 vs. Q4; hazard ratio [HR], 6.75; 95% confidence interval [CI], 1.54 to 29.47; p = 0.011). In multivariate analysis, the risk of developing CKD stage 3 or greater was higher in the second lowest quartile of the serum bilirubin level than that in the highest quartile of the serum bilirubin level (Q2 vs. Q4; HR, 9.36; 95% CI, 1.33 to 65.73; p = 0.024). In the normoalbuminuria subgroup (n = 236), multivariate analysis showed that the risk of developing CKD stage 3 or greater was higher in the lowest quartile of the serum bilirubin level than that in the highest quartile of the serum bilirubin level (Q1 vs. Q4; HR, 7.36; 95% CI, 1.24 to 35.82; p = 0.019). CONCLUSIONS: Serum bilirubin might be an early clinical marker for predicting the progression of CKD in patients with T2DM and preserved renal function.

A Validation Study of the Korean Version of Social Communication Questionnaire

OBJECTIVES: The purposes of this study were to examine the reliability and validity of the Korean version of Social Communication Questionnaire (K-SCQ) and to determine cut-off scores for diagnosis of autism spectrum disorder (ASD). METHODS: A total of 166 subjects with ASD and their 186 unaffected siblings were recruited through child psychiatry clinics of university hospitals. Board certified child psychiatrists screened all probands suspected to have ASD based on the Diagnostic and Statistical Manual of Mental Disorders, fourth edition. To confirm the diagnoses, the Korean versions of the Autism Diagnostic Observation Schedule and the Autism Diagnostic Interview-Revised (K-ADI-R) were administered to all the subjects. All parents completed the K-SCQ and Social Responsiveness Scale (SRS). The non-ASD siblings were evaluated with the same instruments as the probands with ASD. We performed a factor analysis to examine the structure of K-SCQ. For testing the validity of K-SCQ, we compared the difference in Lifetime and Current scores of probands with ASD and their non-ASD siblings using t-test and analysis of covariance. Correlations between the K-SCQ and other measurements of ASD symptomatology, including K-ADI-R totals and domain scores and SRS, were examined. Receiver operation characteristic curve analysis was performed to extract cutoff scores discriminating affection status. RESULTS: Four factors were extracted through factor analysis of K-SCQ ; 1) social relation and play, 2) stereotyped behavior, 3) social behavior, and 4) abnormal language. Cronbach's internal consistency was .95 in K-SCQ Lifetime, and .93 in K-SCQ Current. There were significant differences in total score of K-SCQ, both in Lifetime and Current between the ASD group and non-ASD siblings group (p<.001). K-SCQ scores were significantly correlated with K-ADI-R subdomain scores and SRS total scores (p<.001). The best-estimate cut-off scores of K-SCQ for diagnosis of ASD were 12 for 48 months and over, and 10 for below 47 months. CONCLUSION: Our findings suggest that the K-SCQ is a reliable and valid instrument for screening autistic symptoms in the Korean population. Lower cut-off scores than the original English version might be considered when using it as a screening instrument of ASD.

Association of the Preoperative Neutrophil-to-ymphocyte Count Ratio and Platelet-to-Lymphocyte Count Ratio with Clinicopathological Characteristics in Patients with Papillary Thyroid Cancer

BACKGROUND: Several inflammatory biomarkers, especially a high preoperative neutrophil-to-lymphocyte count ratio (NLR) and platelet-to-lymphocyte count ratio (PLR), are known to be indicator of poor prognosis in several cancers. However, very few studies have evaluated the significance of the NLR and PLR in papillary thyroid cancer (PTC). We evaluated the association of the preoperative NLR and PLR with clinicopathological characteristics in patients with PTC. METHODS: This study included 1,066 female patients who underwent total thyroidectomy for PTC. Patients were stratified into 4 quartiles by preoperative NLR and PLR. And the combination of preoperative NLR and PLR was calculated on the basis of data obtained value of tertile as follows: patients with both an elevated PLR and an elevated NLR were allocated a score of 2, and patients showing one or neither were allocated a score of 1 or 0, respectively. RESULTS: The preoperative NLR and PLR were significantly lower in patients aged > or =45 years and in patients with Hashimoto's thyroiditis. The PLR was significantly higher in patients with tumor size >1 cm (P=0.021).When the patients were categorized into the aforementioned four groups, the group with the higher preoperative PLR was found to have a significantly increased incidence of lateral lymph node metastasis (LNM) (P=0.018). However, there are no significant association between the combination of preoperative NLR and PLR and prognostic factors in PTC patients. CONCLUSION: These results suggest that a preoperative high PLR were significant associated with lateral LNM in female patients with PTC.

Successful Treatment of Duodenal Variceal Bleeding by Endoscopic Clipping

Duodenal varix bleeding is an uncommon cause of gastrointestinal bleeding in patients with portal hypertension but can cause severe and potentially fatal bleeding. However, the incidence is low and a good treatment method has not been well established yet. Duodenal variceal bleeding can be treated surgically or nonsurgically. We have successfully treated a patient with duodenal variceal bleeding secondary to liver cirrhosis using hemoclips to control the bleeding.

A Case of Portal Vein Thrombosis in Acute Necrotizing Pancreatitis Treated with Low-Molecular-Weight Heparin / 대한내과학회지

Portal vein thrombosis can result from the obstruction of blood flow, inflammation, and hypercoagulability of blood. Clinical symptoms include those of bowel ischemia caused by extension of the thrombus, portal hypertension, and gastrointestinal varix bleeding. Cases arising from complications of acute pancreatitis are very rare. The management of portal vein thrombosis varies, but spontaneous resolution of the thrombosis is uncommon. To prevent complications, anticoagulation therapy may be considered. We report a 51-year-old man who was treated successfully with low-molecular-weight heparin for portal vein thrombosis complicating acute necrotizing pancreatitis.

A Case of Duodenal Duplication Cyst Manifested by Duodenal Polyp

Duodenal duplication cyst is a rare anomaly, totaling only 4% to 12% of gastrointestinal duplications, and is usually encountered during infancy or in early childhood. Most are commonly located posterior to the first or second portion of the duodenum. Presenting signs and symptoms include vomiting, decreased oral intake, periumbilical tenderness, abdominal distention, obstructive jaundice, acute pancreatitis, and gastrointestinal bleeding. The traditional treatment of a duodenal duplication cyst has been complete surgical resection, but very few cases of endoscopic treatment have been reported in the literature. Here, we report a case of duodenal duplication cyst that was manifested by a duodenal polyp.

A Case of Liver Abscess and Bacteremia Caused by Vibrio cholerae Non-O1 / 대한소화기학회지

Vibrio cholerae non-O1 have caused several well-studied food-borne outbreaks of gastroenteritis and also have been responsible for sporadic cases of otitis media, wound infection, and bacteremia. Few cases of liver abscess caused by Vibrio cholerae non-O1 have been reported. A 73-year-old man with underlying diabetes mellitus was admitted with nausea, vomiting, dyspepsia and febrile sensation. We identified Vibrio cholerae non-O1 in his blood cultures and multiple hepatic microabscess on abdominal computed tomography. He was treated with systemic antibiotics and fluid therapy, but died due to septic shock on sixth day. We report here, a case of liver abscess with bacteremia due to Vibrio cholerae non-O1 in a patient with diabetes mellitus.
