OBJECTIVES: This study examined the admission type and its related factors among patients with psychotic disorders defined based on the revised mental health welfare law. METHODS: This study was conducted on a total of 100 patients diagnosed on the schizophrenia spectrum and other psychotic disorders. The admission type and sociodemographic characteristics were examined. Social support, psychopathology, excitement, insight, and social functioning were evaluated using the Social Support Scale, Positive and Negative Syndrome Scale (PANSS), PANSS excitement component, Brief Psychiatric Rating Scale, Global Assessment Functioning Scale, Strauss-Carpenter scale, Korean version of the Scale to Assess Unawareness of Mental Disorder, and Korean version of Beck Cognitive Insight Scale. RESULTS: The severity of psychotic symptoms, excitement, social functioning, and insight were significantly different between involuntary and voluntary admissions (p<0.05). Excitement and insight were found to be factors affecting the admission type (p<0.05). CONCLUSION: Excitement and insight were factors mainly accounting for the admission type in patients with psychotic disorder. This study could be helpful in improving clinical decision-making and community mental health care.

PURPOSE: Fibroblast growth factor receptor 4 (FGFR4) plays an important role in cancer progression during tumor proliferation, invasion, and metastasis. This study evaluated the prognostic role of FGFR4 polymorphism in patients with resected colon cancer, including the underlying mechanism. MATERIALS AND METHODS: FGFR4 polymorphism was characterized in patientswho received curative resection for stage III colon cancer. FGFR4-dependent signal pathways involving cell proliferation, invasion, and migration according to genotypes were also evaluated in transfected colon cancer cell lines. RESULTS: Among a total of 273 patients, the GG of FGFR4 showed significantly better overall survival than the AG or AA, regardless of adjuvant treatment. In the group of AG or AA, combination of folinic acid, fluorouracil, and oxaliplatin (FOLFOX) resulted in better survival than fluorouracil/leucovorin or no adjuvant chemotherapy. However, in GG, there was no difference among treatment regimens. Using multivariate analyses, the Arg388 carriers, together with age, N stage, poor differentiation, absence of a lymphocyte response, and no adjuvant chemotherapy, had a significantly worse OS than patients with the Gly388 allele. In transfected colon cancer cells, overexpression of Arg388 significantly increased cell proliferation and changes in epithelial to mesenchymal transition markers compared with cells overexpressing the Gly388 allele. CONCLUSION: The Arg388 allele of FGFR4 may be a biomarker and a candidate target for adjuvant treatment of patients with resected colon cancer.

OBJECTIVE: This study examined the characteristics of suicidal attempters, including pre-hospital patients and those who visited the emergency department. METHODS: Suicidal attempters who had been reported to the 119 call center were selected between July 2015 and June 2016. Sex, age, place, methods of suicidal attempt, season, time, and suicide success rate were reviewed in the fire center records. RESULTS: A total 961 suicide attempters were enrolled. Among them, 53.6% were males who had an approximately 2.6 times higher mortality than that of females (9.2%). The most preferred place to commit suicide was the home in both sexes (68.0% in male, 82.8% in female) and the most preferred methods was drug intoxication, particularly pesticide. The method with the highest mortality was hanging and the lowest was self-harm. The season of the highest mortality was spring. The success of suicide and the time variation were similar. Most of the un-transferred patients also selected fatal suicide attempts compared to transfer patients. CONCLUSION: Unlike previous studies, this study includes information on un-transferred patients. Overall, the probability of death was highest as more than 50 years men chose hanging as a method, which had an influence on the un-transferred patients group.

Percutaneous needle aspiration biopsy is a relatively simple and safe procedure for the diagnosis of lung and mediastinal lesions. Systemic air embolism during and after percutaneous needle aspiration biopsy of the lung is very rare; however, it is still a complication that can cause fatal outcomes, such as cerebral infarction and myocardial infarction. Here, we report a 72-year-old woman who suffered a change in consciousness immediately after receiving a percutaneous needle aspiration biopsy for the pathologic examination of pulmonary nodules found during a routine health medical examination. She had left side weakness and ST segment elevation on an electrocardiogram. After a high concentration of oxygen, she recovered from neurological symptoms and electrocardiographic abnormalities. The authors report a case of air embolism occurring simultaneously in the brain and coronary arteries after percutaneous needle aspiration biopsy.

An aortoesophageal fistula is one of the very few causes of upper gastrointestinal bleeding but can be fatal if the diagnosis is delayed. This usually occurs secondary to esophageal or aortic surgery. A primary aortoesophageal fistula is rare and less likely to be suspected. Here, we present a case of a primary aortoesophageal fistula that presented as massive upper gastrointestinal bleeding. An 81-year-old man with a history of aortic aneurysm had syncope and bright color hematemesis. The aortoesophageal fistula was not diagnosed early enough and the patient died. Therefore, emergency physicians should consider aortoesophageal fistula as a potential cause when encountering upper gastrointestinal bleeding.

Objective: The number of elderly patients in Korea has been on the rise recently, and hence the number of out-of-hospital cardiac arrest (OHCA) elderly patients is also rising. The causes of cardiac arrest for the elderly vary, and, it is difficult to predict the recovery of spontaneous circulation (ROSC) in OHCA patients. Therefore, the purpose of this study was to ascertain the predictive value of arterial blood gas analysis (ABGA) results in achieving ROSC in the elderly. Methods: A retrospective analysis of emergency department patients with OHCA was performed at the Kangwon National University Hospital, Korea from 1 January 2016 to 31 December 2019. The initial ABGA results were compared between two patient groups, those who had achieved a return of spontaneous circulation and those who had not. Univariate and multivariable analyses were performed to elucidate the factors associated with ROSC. Results: Overall, 229 OHCA patients were included in the final analysis. The lactate level was independently related to ROSC. A receiver operating characteristics (ROC) curve was plotted to obtain the best cutoff value. The lactate level <9.85 mmol/L showed the largest area under the ROC curve (AUC) to predict ROSC (AUC, 0.666; 95% confidence interval, 0.588-0.743). Multiple regression analysis was performed using the cutoff value, which was a lactate level of 9.85 (odds ratio, 2.907; 95% confidence interval, 1.432-5.902; P=0.003). Conclusion The ABGA results during the cardiopulmonary resuscitation of OHCA patients, showed that the lactate level was an independent factor associated with ROSC. The lactate cutoff value was 9.85 mmol/L.

PURPOSE: A combination of β1-adrenergic receptor (β₁-AR) blockade and β₂-AR activation might potentially be the novel therapy for treating heart failure. However, the use of β-AR agonists and/or antagonists in the clinical setting is controversial due to the lack of information on cardiac inotropic or chronotropic regulation by AR signaling. METHODS: In this study, we performed a hemodynamic evaluation by examining the force frequency response (FFR), Frank-Starling relationship, and response to non-selective β-AR agonist (isoproterenol) in the hearts isolated from 6-month-old transgenic (TG) mice overexpressing β₁- and β₂-ARs (β₁- and β₂-AR TG mice, respectively). RESULTS: Cardiac physiologic consequences of β₁- and β₂-AR overexpression resulted in a similar maximal response to that of isoproterenol and faster temporary decline of positive inotropic response in β₂-AR TG mice. β₁-AR TG mice showed a pronounced negative limb of FFR, whereas β2-AR TG mice showed high stimulation frequencies with low contractile depression during FFR. Contrastingly, Frank-Starling relationship was equally enhanced in both β₁- and β₂-AR TG mice. CONCLUSION: Hemodynamic evaluation performed in the present study showed a difference between β₁- and β₂-AR signaling, which may be due to a difference in the desensitization of β₁- and β₂-ARs.
