ABSTRACT

Objective@#This study examined the path model predicting suicide attempts (SA) by interpersonal need for suicide desire, acquired capability for suicide, the emotion dysregulation, and depression symptoms in people admitted to hospitals for medical treatment. @*Methods@#A total of 344 participants (200 depressed patients with attempted suicide, 144 depressed patients with suicidal ideation) were enrolled for this study. Depression, anxiety, emotion regulation, interpersonal needs, and acquired capability for suicide were evaluated. A model with pathways from emotion regulation difficulties and interpersonal needs to SA was proposed. Participants were divided into two groups according to the presence of SA or suicidal ideation. @*Results@#Acquired capability for suicide mediated the path from depression to SA. In the path model, difficulties in emotion regulation and interpersonal needs predicted depression significantly. Although depression itself was not significantly related to acquired capability for suicide, depression was significantly related to acquired capability for suicide in suicide attempter group. @*Conclusion@#Interventions with two factors affecting SA will clarify the suicide risk and contribute to finding risk factors.

ABSTRACT

Objective@#Childhood trauma is the most important environmental factor for several psychiatric disorders. Depressed patients with childhood trauma appear to have severe symptoms that frequently recur. This study investigated whether depressed patients with childhood trauma showed attenuated Nogo event-related potentials (ERPs) and source activity during response-inhibition tasks. @*Methods@#Forty-four patients patients with major depressive disorder (MDD) were instructed to perform a Go/Nogo task during electroencephalography. Sensors and source activities of N2 and P3 of the Nogo ERPs were analyzed. The participants’ clinical symptoms were assessed using the Childhood Trauma Questionnaire (CTQ), Beck Depression Inventory, State-Trait Anxiety Inventory, Barratt Impulsivity Scale, and Affective Lability Scale. The participants were divided into two groups (low and high), based on their total CTQ scores. @*Results@#MDD subjects with high CTQ scores showed significantly decreased Nogo P3 amplitudes at the frontal, frontocentral, central, and parietal electrodes than those with low CTQ scores (all p < 0.01). In Nogo P3, the source activities of the right cuneus, right posterior cingulate cortex, right precuneus, left supramarginal gyrus, and left lingual gyrus were significantly lower in the high CTQ group than in the low one (all p < 0.01). There were significant negative correlations between the total CTQ scores and the Nogo P3 amplitudes in the frontocentral (p = 0.03) and parietal regions (p = 0.02), which showed lower source activity in the Nogo P3 condition. @*Conclusion@#Depressed patients with severe childhood trauma showed different Nogo-ERP characteristics, which might reflect inhibitory failure and dysfunction in related brain regions.

ABSTRACT

Objective@#The objective of the present study was to explore causal pathways to understand how second traumatic experiences could affect the development of emotional exhaustion and psychiatric problems. @*Methods@#A total of 582 workers who had jobs vulnerable to secondary traumatic experiences were enrolled for this study. Emotional exhaustion, secondary trauma, resilience, perceived stress, depression, anxiety, and sleep problems were evaluated. A model with pathways from secondary traumatic experience score to depression and anxiety was proposed. The participants were divided into three groups according to the resilience: the low, middle and high resilience group. @*Results@#Resilience was a meaningful moderator between secondary traumatic experiences and psychiatric problems. In the path model, the secondary trauma and perceived stress directly and indirectly predicted perceived stress, emotional exhaustion, depression, anxiety, and sleep problems in all three groups. Direct effects of perceived stress on depression and anxiety were the largest in the low resilience group. However, direct effects of secondary trauma on perceived stress and emotional exhaustion were the largest in the high resilience group. @*Conclusion@#Understanding the needs of focusing for distinct psychological factors offers a valuable direction for the development of intervention programs to prevent emotional exhaustion among workers with secondary traumatic experiences.

ABSTRACT

Objective@#Mismatch negativity (MMN) is known to be associated with neuro-cognition and functional outcomes. Remission and recovery rates are related to the neuro-cognition of patients with schizophrenia. The present study explored the relationship of MMN with remission in patients with schizophrenia. @*Methods@#Forty patients with schizophrenia were recruited and divided into two groups, with or without remission, according to the Remission in Schizophrenia Working Group criteria (RSWGcr). Symptom severity (Positive and Negative Syndrome Scale, PANSS), cognitive function, functional outcome, and MMN of the patients were evaluated. A regression analysis was used to identify the factors that significantly predicted symptom improvement and remission including MMN at frontal site assessed at baseline, and anticipated clinical variables as predictive factors. @*Results@#MMN amplitudes in frontal sites were further decreased in the groups without remission compared to the groups with remission. MMN amplitude was significantly correlated with measures of symptom change and functional outcome measurements in patients with schizophrenia. Regression analysis revealed that symptom severity and MMN significantly predicted remission in patients with schizophrenia. Symptom improvement significantly predicted PANSS at baseline, illness duration, and antipsychotic dose, as did MMN amplitude at frontal site. @*Conclusion@#Our results suggest that MMN reflected symptom improvement and remission in patients with schizophrenia. MMN indices appear to be promising candidates as predictive factors for schizophrenia remission.

ABSTRACT

Background/Aims@#Distinguishing gastric ectopic pancreas (GEP) from malignant tumors is relatively difficult. This study evaluated the endosonography findings of pathologically proven GEP. @*Methods@#Thirty-one patients diagnosed with GEP based on a histopathological analysis from January 2004 to July 2018 were enrolled in this study. All patients underwent EUS and an endoscopic resection. @*Results@#Seventeen patients were female, and the median age was 41.1 years (range, 14-74). The lesions were localized most commonly in the antrum. The mean size of the GEP was 10.6 mm (range, 7-15). Superficial type lesions, lesions with heterogeneous echogenicity, mixed pattern lesions, and lesions with indistinct borders were commonly observed on EUS. Calcification, anechoic duct-like structures, and thickening of the muscularis propria were observed in some patients. Endoscopic mucosal resection (41.9%) and endoscopic submucosal dissection (58.1%) were performed. The mean procedure time was 22.5 minutes. Complete resection was achieved for 71% of patients. No statistically significant results between the endosonography findings and complete resection rates were obtained. The mean follow-up esophagogastroduodenoscopy duration was 4.5 months. None of the patients presented with residual lesions on subsequent endoscopy. @*Conclusions@#EUS can help identify the features of GEP. Careful observations of the EUS findings can avoid unnecessary removal of GEP.

ABSTRACT

OBJECTIVE: We examined associations between emotional exhaustion and selected sociodemographic and psychological factors among nurses in inpatient and outpatient nursing units at a university hospital in South Korea. METHODS: The participants were 386 nurses who completed the Maslach Burnout Inventory, a measure of emotional exhaustion. Psychological characteristics were evaluated, including hardiness, self-esteem, experience of trauma, resilience, perceived stress, and social support. Correlation analyses examined the relationships between emotional exhaustion with sociodemographic, occupational, and psychological characteristics. Linear regression was used to evaluate the associations between emotional exhaustion and the assessed characteristics. RESULTS: Higher emotional exhaustion scores were associated with greater depression, anxiety, traumatic experience, and perceived stress. Exhaustion was inversely associated with hardiness, self-esteem, resilience, and quality of life. The regression analysis indicated that gender, marriage, resilience, depression, perceived stress, and secondary traumatic stress were significantly associated with emotional exhaustion. CONCLUSION: This study showed that psychological characteristics, such as resilience, depression, and secondary traumatic experiences, may cause emotional exhaustion. Understanding the needs of people with distinct demographic and psychological characteristics offers valuable direction for the development of intervention programs to prevent burnout among nurses.

ABSTRACT

PURPOSE: Viral infections are involved in ~50% of exacerbations among Caucasian adult asthmatics. However, there have been few reports on the causative virus of exacerbations in Korean adult asthmatics. Thus, we compared frequencies and types of viruses between lower respiratory tract illnesses (LRTIs) with exacerbations (exacerbated LRTIs) and those without exacerbations (stable LRTIs) to evaluate contribution of respiratory viruses to exacerbations. METHODS: Viral RNA was extracted from sputum using the Viral Gene-spin™ Kit. Reverse transcription-polymerase chain reaction (RT-PCR) was performed to detect adenovirus (ADV), metapneumovirus (MPV), parainfluenza virus (PIV) 1/2/3, influenza virus (IFV) A, IFV B, respiratory syncytial virus (RSV) A/B, and rhinovirus (RV) A. RESULTS: Among the 259 patients, 210 underwent a single sputum examination, and the remaining 49 underwent 2 to 4 sputum examinations. Virus was detected in 68 of the 259 exacerbated episodes and in 11 of the 64 stable episodes. Among the exacerbated episodes, RV was the most frequently detected virus, followed by influenza A, parainfluenza, RSV A/B, and ADV. Among the 11 stable episodes, RV was most frequently detected. Detection rates of these viruses did not differ between the 2 groups (P>0.05). Thirty-five patients underwent the virus examination at 2 episodes of exacerbation, while 14 patients underwent at each time of exacerbated and stable episodes. Virus detection rate at the second examination was significantly higher in cases with 2 exacerbation episodes than in those with initial exacerbation and sequential stable episodes (P=0.003). A seasonal pattern was noted in the detection rates of RV (September to December), IFV (January to April), PIV (May to September), and RSV A/B (September to April). CONCLUSIONS: Respiratory viruses were identified in approximately 20% of LRTI irrespective of the presence of asthma exacerbation. RV and IFV A/B were most frequently detected. A group of patients experienced frequent viral infections followed by asthma exacerbations.

ABSTRACT

OBJECTIVE: We aimed to identify depressive symptom profiles that indicated the presence of depressive disorder and present optimal cut-off sub-scores for depressive symptom profiles for detecting depressive disorder in elderly subjects with chronic physical diseases including diabetes, chronic obstructive pulmonary disease/asthma, and coronary artery disease, using the Patient Health Questionnaire-9 (PHQ-9). METHODS: Two hundred and thirty-one elderly patients with chronic physical diseases were recruited consecutively from a university-affiliated general hospital in South Korea. RESULTS: Greater severities of all 9 depressive symptoms in the PHQ-9 were presented in those with depressive disorder rather than those without depressive disorder. A binary logistic regression modeling presented that little interest [adjusted odds ratio (aOR)=4.648, p<0.001], reduced/increased sleep (aOR=3.269, p<0.001), psychomotor retardation/agitation (aOR=2.243, p=0.004), and concentration problem (aOR=16.116, p<0.001) were independently associated with increased likelihood of having depressive disorder. Receiver operating characteristics (ROC) curve analysis presented that the optimal cut-off value of score on the items for little interest, reduced/increased sleep, psychomotor retardation/agitation and concentration problem (PHQ-9) for detecting depressive disorder was 4 with 61.9% of sensitivity and 91.5% of specificity [area under curve (AUC)=0.937, p<0.001]. CONCLUSION: Our findings suggested that the diagnostic weighting of little interest, reduced/increased sleep, psychomotor retardation/agitation, and concentration problem is needed to detect depressive disorder among the elderly patients with chronic physical diseases.

ABSTRACT

Pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma is a rare disease and usually presents as pulmonary masses, mass-like consolidation, or pulmonary nodules on chest images. We report a case of a 43-year-old man with symptoms of chronic cough for 1 year, showing bilateral diffuse bronchovascular bundle thickening and focal ground glass opacities on a chest computed tomography scan. Video-assisted thoracoscopic surgery was performed and the final pathologic diagnosis was pulmonary MALT lymphoma. Concurrent involvement of the pancreas was discovered during staging workup. After diagnosis, he was treated with cytotoxic chemotherapy and rituximab and showed improvements in his lung lesion and pancreas.

ABSTRACT

Our study aimed to examine the knowledge and attitude of nursing personnel toward depression in general hospitals of Korea. A total of 851 nursing personnel enrolled at four university-affiliated general hospitals completed self-report questionnaires. Chi-square tests were used to compare the knowledge and attitude of registered or assistant nurses toward depression. In addition, binary logistic regression analysis was used to adjust for the following confounders: age-group and workplace. Registered and assistant nurses differed in their knowledge and attitude toward depression. The proportion of rational and/or correct responses were higher in registered nurses than assistant nurses for the following: constellation of depressive symptoms defined by DSM-IV (adjusted odds ratio [aOR], 3.876; P<0.001); suicide risk in depression recovery (aOR, 3.223; P=0.001) and psychological stress as a cause of depression (aOR, 4.370; P<0.001); the relationship between chronic physical disease and depression (aOR, 8.984; P<0.001); and other items. Our results suggest that in terms of the biological model of depression, the understanding of registered nurses is greater than that of assistant nurses. Moreover, specific psychiatric education programs for nursing personnel need to be developed in Korea. Our findings can contribute to the development of a general hospital-based model for early detection of depression in patients with chronic medical diseases.

ABSTRACT

OBJECTIVES: Argon plasma coagulation (APC) is a noncontact form of electrocautery that utilizes ionized argon as the electrical current. A rigid bronchoscopic use of APC for the management of central airway obstruction could be safe and rapidly effective. This study evaluated the usefulness of rigid bronchoscopy with APC for the management of central airway obstructions due to benign or malignant tumors. METHODS: Twenty patients with obstructing central airway tumors were retrospectively reviewed from February 2008 to February 2013 at Chonnam National University Hospital. All patients received rigid bronchoscopic tumor removal under general anesthesia. APC was applied before and after tumor removal. RESULTS: The median age of patients was 59 years (interquartile range [IQR], 51 to 67 years) and 70% were female. The causes of airway obstruction included malignancy (n=8) and benign tumor (n=12). Airway tumors comprised intraluminal lesions (n=11, 55%) and mixed intraluminal/extraluminal lesions (n=9, 45%). The median tumor size was 15 mm (IQR, 10 to 18 mm). The median degree of airway obstruction was significantly reduced after intervention (90% [IQR, 88% to 96%] vs. 10% [IQR, 0% to 20%], P<0.001). The median American Thoracic Society dyspnea grade (3 [IQR, 1 to 4] vs. 1 [IQR, 0 to 1], P<0.001) and forced expiratory volume in one second (1.03 L [IQR, 0.52 to 1.36 L] vs. 1.98 L [IQR, 1.57 to 2.64 L], P=0.004) were significantly improved after intervention. There were no procedure-related acute complications and deaths. CONCLUSION: Rigid bronchoscopy with APC is an effective and safe procedure to alleviate central airway obstruction caused by tumors.

ABSTRACT

We investigated the combined moisturizing effect of liposomal serine and a cosmeceutical base selected in this study. Serine is a major amino acid consisting of natural moisturizing factors and keratin, and the hydroxyl group of serine can actively interact with water molecules. Therefore, we hypothesized that serine efficiently delivered to the stratum corneum (SC) of the skin would enhance the moisturizing capability of the skin. We prepared four different cosmeceutical bases (hydrogel, oil-in-water (O/W) essence, O/W cream, and water-in-oil (W/O) cream); their moisturizing abilities were then assessed using a Corneometer(R). The hydrogel was selected as the optimum base for skin moisturization based on the area under the moisture content change-time curves (AUMCC) values used as a parameter for the water hold capacity of the skin. Liposomal serine prepared by a reverse-phase evaporation method was then incorporated in the hydrogel. The liposomal serine-incorporated hydrogel (serine level=1%) showed an approximately 1.62~1.77 times greater moisturizing effect on the skin than those of hydrogel, hydrogel with serine (1%), and hydrogel with blank liposome. However, the AUMCC values were not dependent on the level of serine in liposomal serine-loaded hydrogels. Together, the delivery of serine to the SC of the skin is a promising strategy for moisturizing the skin. This study is expected to be an important step in developing highly effective moisturizing cosmeceutical products.

ABSTRACT

This study was aimed to observe that extremely low frequency magnetic field (ELF-MF) may be relevant to changes of major neurotransmitters in rat brain. After the exposure to ELF-MF (60 Hz, 2.0 mT) for 2 or 5 days, we measured the levels of biogenic amines and their metabolites, amino acid neurotransmitters and nitric oxide (NO) in the cortex, striatum, thalamus, cerebellum and hippocampus. The exposure of ELF-MF for 2 or 5 days produced significant differences in norepinephrine and vanillyl mandelic acid in the striatum, thalamus, cerebellum and hippocampus. Significant increases in the levels of serotonin and 5-hydroxyindoleacetic acid were also observed in the striatum, thalamus or hippocampus. ELF-MF significantly increased the concentration of dopamine in the thalamus. ELF-MF tended to increase the levels of amino acid neurotransmitters such as glutamine, glycine and gamma -aminobutyric acid in the striatum and thalamus, whereas it decreased the levels in the cortex, cerebellum and hippocampus. ELF-MF significantly increased NO concentration in the striatum, thalamus and hippocampus. The present study has demonstrated that exposure to ELF-MFs may evoke the changes in the levels of biogenic amines, amino acid and NO in the brain although the extent and property vary with the brain areas. However, the mechanisms remain further to be characterized.

ABSTRACT

OBJECTIVES: Depression is commonly comorbid in elderly patients with physical illness. This study examined the prevalence of depression in the elderly with Diabetes Mellitus (DM). METHODS: Eighty-nine patients, over 60 years old, with DM were enrolled. The medical and psychiatric history, Hamilton Rating Scale for Depression (HDRS), Patient Health Questionnaire-9 (PHQ-9), Geriatric Depression Scale-Short form Korean (GDS-SF-K), and Mini-Mental Status Examination Korean version were examined. RESULTS: The prevalence of depression was estimated as 21.3% (male 4.5% ; female 16.9%) in HDRS, 32.6% (male 9.0% ; female 23.6%) in PHQ-9, and 24.7% (male 5.6% ; female 19.1%) in GDS-SF-K. CONCLUSION: The self-reporting scale, such as GDS-SF-K, PHQ-9 is an effective screening test for depression. The prevalence of elderly depression with DM ranged from 20% to 30%, the prevalence of depression is almost three times more common in women.

ABSTRACT

Chronic sputum is a troublesome symptom in many respiratory diseases. The prevalence of chronic sputum varies from 1.2% to 13% according to the country. The purpose of this study was to estimate the prevalence of chronic sputum and to find its associated factors in a general Korean population. We analyzed the data of the Korea National Health and Nutrition Examination Survey 2010 and 2011. A total number of 6,783 subjects aged 40 yr or more were enrolled in this study with 3,002 men and 3,781 women. As a result, the prevalence of chronic sputum was 6.3% (n=430). Significant risk factors for chronic sputum by multivariate analysis were: age (> or =70 yr) (odds ratio [OR], 1.954; 95% confidence interval [CI], 1.308-2.917), current smoking (OR, 4.496; 95% CI, 3.001-6.734), chronic obstructive pulmonary disease (COPD) (OR, 1.483; 95% CI, 1.090-2.018), and tuberculosis (OR, 1.959; 95% CI, 1.307-2.938). In conclusion, the prevalence of chronic sputum in Korea was in the intermediate range compared with other countries. Smoking is a preventable risk factor identified in this study, and major respiratory diseases, such as COPD and tuberculosis, should be considered in subjects with chronic sputum.

ABSTRACT

Crizotinib-associated severe hepatotoxicity has been rarely reported and experts recommended stopping crizotinib treatment in patients with grade 3/4 transaminase elevation. We experienced a case of anaplastic lymphoma kinase-positive non-small cell lung cancer occurring as a result of severe hepatotoxicity due to crizotinib-associated hepatitis, accompanied by the reactivation of chronic hepatitis B, which was reversed with dose reduction and anti-viral therapy. Our case highlights the possibility that crizotinib might induce hepatitis and this might be associated with the underlying presence of chronic hepatitis B. In addition, crizotinib could be continued with reduced unless there are any other therapeutic options.

ABSTRACT

Soybean polyunsaturated phosphatidylcholine (PC) is thought to exert anti-inflammatory activities and has potent effects in attenuating acute renal failure and liver dysfunction. The aim of this study was to investigate the effects of PC in protecting multiple organ injury (MOI) from lipopolysaccharide (LPS). Six groups of rats (N=8) were used in this study. Three groups acted as controls and received only saline, hydrocortisone (HC, 6 mg/kg, i.v.) or PC (600 mg/kg, i.p.) without LPS (15 mg/kg, i.p.) injections. Other 3 groups, as the test groups, were administered saline, HC or PC in the presence of LPS. Six hours after the LPS injection, blood and organs (lung, liver and kidney) were collected from each group to measure inflammatory cytokines and perform histopathology and myeloperoxidase (MPO) assessment. Serum cytokines (TNF-alpha, IL-6 and IL-10) and MPO activities were significantly increased, and significant histopathological changes in the organs were observed by LPS challenge. These findings were significantly attenuated by PC or HC. The treatment with PC or HC resulted in a significant attenuation on the increase in serum levels of TNF-alpha and IL-6, pro-inflammatory cytokines, while neither PC nor HC significantly attenuated serum levels of IL-10, anti-inflammatory cytokine. In the organs, the enhanced infiltration of neutrophils and expression of ED2 positive macrophage were attenuated by PC or HC. Inductions of MPO activity were also significantly attenuated by PC or HC. From the findings, we suggest that PC may be a functional material for its use as an anti-inflammatory agent.

ABSTRACT

OBJECTIVES: Depression is commonly comorbid in the elderly patients with physical illness. This study examined the prevalence of depression in the elderly with chronic obstructive pulmonary disease (COPD). METHODS: The eighty-seven patients with COPD were enrolled. The subjects are over 60 years old. The medical and psychiatric history, Hamilton Rating Scale for Depression (HDRS), Patient Health Questionnaire-9 (PHQ-9), Patient Health Questionnaire-2 (PHQ-2), Geriatric Depression Scale-Short form Korean (GDS-SF-K), Mini-Mental Status Exam Korean version (MMSE-KC) were investigated. Global Initiative for Chronic Obstructive Lung Disease (GOLD), which predict the severity of COPD, also investigated. RESULTS: The prevalence of depression was estimated to be 24.7% (male 19.3% ; female 35.7%) in HDRS, 31.0% (male 24.6% ; female 43.3%) in PHQ-9, 8.0% (male 10.5% ; female 3.3%) in PHQ-2, 23.0% (male 17.5% ; female 33.3%) in GDS-SF-K. The severity of COPD (GOLD) was associated with the prevalence of depression (HDRS, p=0.027 ; PHQ-9, p=0.045 ; PHQ-2, p=0.112 ; GDS-SFK, p=0.089). CONCLUSION: The prevalence of elderly depression with COPD ranged from about 20% to 30%, the prevalence of depression is nearly two times more common in women. The severity of COPD (GOLD) was associated with the prevalence of depression. The self-reporting scale, such as GDS-SF-K, PHQ-9 and PHQ-2 is the effective screening test of depression.

ABSTRACT

BACKGROUND: Hemoptysis due to pulmonary tuberculosis (TB) frequently develops in Korea where the prevalence of TB is intermediate. The effect of bronchial artery embolization (BAE) on the control of massive hemoptysis has been well known. This study is designed to identify the risk factors contributing to rebleeding after BAE in patients with TB. METHODS: We retrospectively evaluated risk factors and the time for rebleeding after BAE in 72 patients presenting with hemoptysis. RESULTS: The overall immediate success rate of BAE was 93.1% (67 of 72 patients). Of the 29 patients (40.3%) who showed rebleeding after BAE, 13 patients experienced rebleeding within 1 month, and 14 patients between 1 month to 1 year. The existence of a shunt in angiographic finding, aspergilloma, and diabetes mellitus were risk factors of rebleeding after BAE in multivariate analysis. CONCLUSION: BAE was very effective for obtaining immediate bleeding control in hemoptysis associated with active TB or post-TB sequelae. It is important to observe whether or not rebleeding occurs up to 1 year of BAE especially in TB patients with aspergilloma, DM, or a shunt. Even rebleeding can be managed well by second BAE.

ABSTRACT

In patients with advanced non-small cell lung cancer harboring epidermal growth factor receptor (EGFR) mutations, the epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) are used as first treatment option. Because adenosquamous carcinoma (ASC) is a rare histologic subtype, evidences about EGFR-TKIs as first treatment option for advanced ASC are lacking. We report a case of an advanced ASC patient with the EGFR mutation, who showed good responses during 4-month treatment with gefitinib. And we will review about a necessity of EGFR mutation test and efficacy of EGFR-TKIs in ASC patients from the recent studies.
