RESUMO
Fluid overload is an independent risk factor of mortality in patients with acute kidney injury (AKI) receiving continuous kidney replacement therapy (CKRT). However, the association between fluid status, as assessed by bioelectrical impedance analysis (BIA) or lung ultrasound, and survival in patients with AKI requiring CKRT has not been established. Methods: We analyzed 36 participants with sepsis-associated AKI who received CKRT at a tertiary hospital. The main exposures were volume surrogates: 1) overhydration normalized by extracellular water (OH/ECW, L/L) assessed by BIA, 2) the number of B-lines measured by lung ultrasound, and 3) weight change ([body weight at CKRT initiation – body weight at admission] × 100/body weight at admission). The primary outcome was the 28-day mortality. Results: Seventeen participants (47.2%) died within 28 days. There were no significant correlations between OH/ECW and weight change (R2 = 0.040, p = 0.24), number of B-lines and OH/ECW (R2 = 0.056, p = 0.16), or weight change and number of B-lines (R2 = 0.014, p = 0.49). Kaplan-Meier analyses revealed that patients in the highest tertile of OH/ECW showed a significantly lower cumulative 28-day survival probability than the others (the lowest + middle tertiles). The survival probability of participants in the highest tertile of the number of B-lines or weight change did not differ from that of their counterparts. In a multivariate Cox proportional hazard model, the hazard ratio for the highest tertile of OH/ECW was 3.83 (95% confidence interval, 1.04–14.03). Conclusion: Volume overload assessed using BIA (OH/ECW) was associated with the 28-day survival rate in patients with sepsis-associated AKI who received CKRT.
RESUMO
objectives@#:The purpose of this study is to determine whether there is a significant difference in the neutro-phil-to-lymphocyte ratio and platelet-to-lymphocyte ratio according to the history of suicide attempt in patients with psychiatric diseases. @*Methods@#:A medical record review was conducted on patients who had been hospitalized in Konyang University Hospital since 2021-03-01 to 2023-02-28 to collect demographic and clinical characteristics. T-test for continuous variables and Chi-square test for categorical variables were performed to determine demographic differences according to the history of suicide attempt, and the ANCOVA test was performed to compare the average value of peripheral inflammatory marker according to the history of suicide attempt with gender and age as co-variates. One-way variance analysis was performed to determine whether the number of suicide attempt causes significant difference of the peripheral inflammatory marker. @*Results@#:The final analysis target of this study was 266 patients, 101 had history of suicide attempt, and 165 had no history of suicide attempt. The neutrophil-to-lymphocyte ratio (p<0.001) and platelet-to-lymphocyte ratio (p<0.001) were higher in patients with the history of suicide attempt than patients without the history of suicide attempt, but the neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio were not significantly in-creased depending on the serial increase of number of suicide attempts. @*Conclusions@#:This study suggests that peripheral inflammatory markers are meaningful and easily accessible indicators for predicting the risk of suicide attempt in psychiatric patients. We expect that prospective follow-up study will be conducted with more subjects and controlled potential confounding variables.
RESUMO
Objectives@#:This study was conducted to investigate the effect of 1-year administration of second-generation antipsychotics (SGAs) on the platelet activity in patients with schizophrenia through a retrospective review of the medical records. @*Methods@#:The mean platelet component (MPC) value was used as an index of the platelet activity. The included subjects (N=24) were the patients who were confirmed to have taken SGAs continuously for one year after the first MPC measurement had been performed. The change of MPC was verified through a paired sample t-test. @*Results@#:The result revealed that the mean MPC value was significantly decreased from 26.5±1.4 g/dL to 25.6±1.8 g/dL after 1-year administration of SGAs from the time of the first MPC measurement. @*Conclusions@#:This study suggests that 1-year administration of SGAs may be related with increased platelet activity, and that close monitoring for risks such as cerebrovascular/cardiovascular or thromboembolic diseases may be necessary during SGAs treatment in clinical practice.
RESUMO
Objectives@#: In this study, we evaluate psychological stress, symptoms of anxiety and depressed mood and resilience which medical residents and interns perceived during COVID-19 event, then investigate the associations between stress and the symptoms and mediating effect of resilience on the associations. @*Methods@#: In this study, we made a self-reporting form to evaluate psychological stress with perceived stress scale (PSS), symptoms of anxiety and depressed mood with Hospital anxiety and depression scale (HAD), and resilience with Conner-Davidson Resilience Scale (CD-RISC). Medical residents and interns, who worked in a hospital during COVID-19 event, filled the self-reporting forms from july, 2020 to august, 2020. We conducted a Pearson correlation coefficient and a multiple regression to confirm association between psychological stress and symptoms of anxiety and depressed mood, then mediating effect of resilience. @*Results@#: The higher stress perceived, the more symptoms of anxiety and depressed mood were reported by medical residents and interns. The higher resilience is associated with lower stress and less symptoms of anxiety and depressed mood, which resilience is proven to mediate partially the association between stress and symptoms of depressed mood. @*Conclusions@#: This study shows that resilience has a partial mediating effects on the association between stress and psychological pathology especially depressed mood, given that medical residents and interns were under psychological distress during COVID-19 event. This suggests that resilience is the key for medical trainees to overcome the future crisis like COVID-19 event.
RESUMO
Objectives@#:The aim of the present study is to investigate the impact of COVID-19 on the incidence and severity of childhood and adolescent self-harm. @*Methods@#:Medical records were retrospectively reviewed for patients under the age of 18 who visited the emergency room of Konyang University Hospital to compare the rate of self-harm attempts and the demographic, clinical, and self-harm-related of self-harm attempters aspects before and after the COVID-19 outbreak. @*Results@#:During 11 months after the COVID-19 outbreak, the proportion of the number of children and adolescents patients with self-harm and their episodes increased significantly compared to that during 11 months be-fore the COVID-19 outbreak (χ2 =14.397, p<0.001; χ2 =24.156, p<0.001). Between about the year before and after the outbreak of COVID-19, there was a significant difference in the prior self-harm history and psychiatric history among children and adolescents who visited the emergency room and the ratio of hospitalization to other departments than department of psychiatry (p<0.05; p<0.05; p<0.05). @*Conclusions@#:In the COVID-19 situation, the proportion of children and adolescents who visited the emergency room due to self-harm and admission to other departments are increasing. And it has been shown that the inci-dence of self-harm has significantly increased in children and adolescents with a history of prior self-harm and psychiatric past history. These findings underscore the need for the psychiatric evaluation and intervention of self-harm related high-risk groups among children and adolescents in pandemic situations.
RESUMO
Objectives@#:Clozapine has been known to increase the possibility of developing cardio/cerebrovascular diseases, and the platelet activation has been deemed to be related to the occurrence of them. In author’s previous study, we observed the increase of platelet activity with short-term clozapine administration. This study was conducted, as a follow-up study, to investigate the effect of clozapine on the platelet activity when administered continuously for long-term period of time of 1 year. @*Methods@#:The medical records of the patients with schizophrenia or schizoaffective disorder who were treated with clozapine for 1 year were retrospectively reviewed. The degree of platelet activation was assessed by measuring the mean platelet component. @*Results@#:Total of 24 patients were enrolled. 9 of them (37.5%) were male and 15 of them (62.5%) were female. In the Wilcoxon sign-ranks test, no significant change was observed between the mean platelet factor values at the beginning and at the end of one year. @*Conclusions@#:No significant changes of mean platelet activity were observed after continued administration of clozapine for 1 year. Considering the author’s previous findings that observed a prominent decrease of mean platelet component after short-term clozapine administration, the result of this study suggests the possibility that the activity of the platelet may change depending on the duration of the clozapine administration.
RESUMO
Background@#The 24-hour uric acid excretion measurement is important in assessing disease status and helping to select the appropriate uric acid-lowering agent for patients with gout, however, it is inconvenient. The authors investigated the efficacy of the random urine uric acid-to-creatinine (UA/CR) ratio to screen the patients who under-secreted 24-hour urine uric acid. @*Methods@#This was a retrospective cross-sectional study. Ninety patients with gout, without undergoing uric acid-lowering treatment were enrolled. Twenty-four-hour urine and random urine samples were obtained on the same day. Six hundred mg of uric acid in the 24-hour urine sample was used as a standard for distinguishing between over and under-excretion groups. @*Results@#The random urinary UA/CR ratio showed positive correlation with 24-hour urine uric acid excretion (γ = 0.398, P < 0.001). All the patients with the random UA/CR less than 0.2 excreted less than 600 mg uric acid in 24-hour urine collection. When the random urine UA/CR ratio < 0.2 was regarded as a positive result, the positive predictive value, negative predictive value, sensitivity, and specificity in the uric acid under-excretion were 100% (8 of 8), 64.6% (53 of 82), 21.6% (8 of 37), and 100% (53 of 53), respectively. @*Conclusion@#There is a moderate positive correlation between the random urinary UA/CR ratio and 24-hour urine uric acid excretion, so that UA/CR ratio may not be a good predictor of 24-hour urine uric acid excretion. However, the random urine UA/CR ratio 0.2 can be a useful predictor to screen the gouty patients who need to be treated with uricosuric drugs.

RESUMO
Uniform mixing of liquid substances is difficult to attain. Recently, mixtures of fat and platelet-rich plasma (PRP) have been used extensively in autologous fat transfer. Although various methods have been utilized to mix the fat and PRP involved in this procedure, these methods still carry disadvantages in the time taken and the potential for cell damage, and it is questionable whether effective mixing can occur using these techniques. To facilitate mixing that is as uniform as possible, the authors of this study invented a special cannula. Use of the conventional luer-lock-to-luer-lock connector method has been found to cause cell damage and makes it difficult to achieve uniform mixing, while random injection-type mixing has been shown to have limited accuracy and effectiveness. We expect that the newly designed cannula will solve the problem detailed above.

Patients receiving hemodialysis are vulnerable to infectious diseases due to their impaired immunity and high risk of exposure to pathogens. To protect patients, staff, and visitors from potential infections, each hemodialysis unit should establish and follow standard infection control and prevention measures. Therefore, clinical practice guidelines were developed by a working group of nephrologists and infection control specialists to provide evidence-based guidance for dialysis physicians and nurses, with the aim of preventing infection transmission and controlling infection sources in hemodialysis facilities. The areas of infection control covered by these guidelines include standard precautions, isolation strategies, vascular access, water treatment, cleaning/disinfecting/sterilizing, and vaccination. This special report summarizes the key recommendations from the Korean clinical practice guidelines for preventing the transmission of infections in hemodialysis facilities.

PURPOSE: This study investigated the effectiveness of meaning-centered psychotherapy (MCP), which is known to be a helpful psychotherapeutic intervention in distressing conditions, for patients with pancreatobiliary cancer. MATERIALS AND METHODS: We recruited 37 patients with pancreatobiliary cancer from three university general hospitals and assessed their psychological characteristics. Patients who reported clinically significant emotional distress were recommended to undergo MCP. Patients who consented to MCP were provided four sessions of the therapy. Patient psychological characteristics were assessed again 2 months after MCP. For statistical comparison, outcome variables included anxiety, depression, mental adjustment to cancer, and quality of life (QoL), as well as the degree of stress and physical symptoms. RESULTS: Sixteen patients completed the MCP and the final assessment 2 months later. In the initial assessment, the patients receiving MCP showed higher levels of anxiety and depression than those not receiving MCP, and QoL was also lower in terms of role function, emotional function, social function, and global QoL. At the 2-month follow-up, the MCP group showed a significant improvement in anxiety (p=0.007), depression (p=0.010), and anxious preoccupation (p < 0.001). In addition, QoL significantly improved in the MCP group, while there was no significant change in the non-MCP group. CONCLUSION: In this study, MCP showed potential therapeutic benefits against emotional distress in patients with pancreatobiliary cancer, improving their QoL.

OBJECTIVES: Clozapine is a widely prescribed antipsychotic drug for schizophrenia and is known to increase the risk of cardiovascular disease due to its metabolic side effects. However, little is known about the effect of clozapine on the platelet activation, another important factor in the development of cardiovascular disease. In this study, we tried to investigate the effect of clozapine on platelet activity in patients with schizophrenia by comparing the mean platelet component (MPC) values before and after the clozapine administration. METHODS: A retrospective review of medical records of patients with schizophrenia, who newly started clozapine treatment from September 1st, 2003 to April 30th, 2007 at the Department of Psychiatry, Konyang University Hospital in Republic of Korea was performed. The final statistical analysis included 14 participants. Bayer ADVIA 120® system was used to measure MPC. RESULTS: Among the 14 participants, five subjects were males (28.60%), and ten subjects were females (71.40%). The mean age of participants was 37.50±11.64 years. Average of duration of illness was 91.00±93.96 months, with the mean dosage of clozapine taken by participants at the time of the last blood test was 337.50±109.52 mg. The mean MPC measurement before and after receiving clozapine was 26.12±2.22 g/dL and 25.14±2.08 g/dL respectively. Wilcoxon signed rank test showed that there was a statistically significant decrease in MPC levels after clozapine administration (V=16, p=0.024). CONCLUSIONS: Decreased MPC levels after clozapine administration implies that clozapine may increase platelet activation which could have an adverse effect on the occurrence of thromboembolic disease. Our findings also suggest that careful monitoring of the risk factors of cardiovascular diseases, such as platelets activity, is necessary when administering clozapine.

OBJECTIVES: Depression is a common mental illness and a major cause of suicide. Although serum lipids have been associated with depression and suicide, there has been much debate. In this study, we investigated the relationship between depression, suicide, and serum lipids in patients admitted with depressed mood. METHODS: A total of 134 subjects were divided into 86 non-suicide patients and 48 suicide attempters. The serum lipid levels and sub-scores of the Korean Symptom Checklist-95 (KSCL95) were compared. We also investigated the relationship between serum lipids and sub-scores of KSCL95 and investigated whether serum lipids were risk factors for suicide attempts. RESULTS: There was no difference in serum lipids between the two groups. Among the sub-items of KSCL95, obsession was higher in non-suicide group. Triglyceride showed positive correlations with anxiety, phobic anxiety, agoraphobia, schizophrenia, and self-regulation problem. High triglyceride was a risk factor for suicide attempts. CONCLUSIONS: Triglyceride is associated with depression, anxiety, and self - regulation, and high serum triglyceride levels may be a risk factor for suicide attempts.

Empathy is the ability to identify with or make a vicariously experience of another person's feelings or thoughts based on memory and/or self-referential mental simulation. The default mode network in particular is related to self-referential empathy. In order to elucidate the possible neural mechanisms underlying empathy, we investigated the functional connectivity of the default mode network in subjects from a general population. Resting state functional magnetic resonance imaging data were acquired from 19 low-empathy subjects and 18 medium-empathy subjects. An independent component analysis was used to identify the default mode network, and differences in functional connectivity strength were compared between the two groups. The low-empathy group showed lower functional connectivity of the medial prefrontal cortex and anterior cingulate cortex (Brodmann areas 9 and 32) within the default mode network, compared to the medium-empathy group. The results of the present study suggest that empathy is related to functional connectivity of the medial prefrontal cortex/anterior cingulate cortex within the default mode network. Functional decreases in connectivity among low-empathy subjects may reflect an impairment of self-referential mental simulation.

OBJECTIVES: Although the Attention Network Test(ANT) has been widely used to assess selective attention including alerting, orienting, and conflict processing, data on its test-retest reliability are lacking for clinical population. The objective of the current study was to investigate test-retest reliability of the ANT in healthy controls and patients with schizophrenia. METHODS: Fourteen patients with schizophrenia and 23 healthy controls participated in the study. They are tested with ANT twice with 1 week interval. Test–retest reliability was analyzed with Pearson and Intra-class correlations. RESULTS: Patients with schizophrenia showed high test–retest correlations for mean reaction time, orienting effect, and conflict effect. Also, they showed moderate to high test-retest correlations for mean accuracy and moderate test-retest correlations for alerting effect and conflict error rate. On the other hand, healthy controls revealed high test–retest correlations for mean reaction time and moderate to high test-retest correlations for conflict error rate. In addition, they revealed moderate test-retest correlations for alert effect, orienting effect, and conflict effect. CONCLUSIONS: The mean reaction time, alerting effect, orienting effect, conflict effect, and conflict error rate of ANT showed acceptable test–retest reliabilities in healthy controls as well as patient with schizophrenia. Therefore, the analyses of these reliable measures of ANT are recommended for case-control studies in patients with schizophrenia.

OBJECTIVES: There has been long lasting trend of deinstitutionalization and public health centered care in management of individuals with disabling mental illness. We aimed to investigate current vocational rehabilitation state and effectiveness of system in korea. METHODS: We carried basic survey via telephone and e-mail beforehand to figure out how many and which institutions are operating vocational rehabilitation programs to psychiatric patients. A questionnaire packages were sent to total of 108 institutions in Korea which were operating occupation rehabilitation program. RESULTS: Of 108 institutions, 40.74% were returned with answers. The person in charge of vocational rehabilitation at each institution was mainly mental health social worker(48.8%), and the budget under \1,000,000 was the majority(61.5%) among surveyed institutions. The most commonly used vocational rehabilitation programs was case management(23.1%), followed by psychosocial rehabilitation program(21.2%), and on-the-job training(17.9%). The most effective program was case management(27.4%), followed by psychosocial rehabilitation program(19.8%), on-the-job training(17.9%). The main barrier of occupation rehabilitation to be conducted widely was ‘worries about being excluded from beneficiary of National Basic livelihood Protection Act’. CONCLUSIONS: Our results suggest that, in spite of high demand in vocational rehabilitation programs, government financial support is still lacking.

OBJECTIVES: The objective of this study was to investigate the characteristics of language profiles according to whether or not Korean children with autism spectrum disorder(ASD) also have ADHD, and to examine the relationship with executive function. METHODS: Participants in the study were boys with ADHD aged 6 to 11 years who visited the clinic from January 2012 to December 2013. In this study, 25 boys with ASD were included, and completed scales included the Korean version of Autism Diagnostic Interview-Revised(K-ADI-R), Korean version of Autism Diagnostic Observation Schedule(K-ADOS), Korean ADHD Rating Scale(K-ARS), and Korean-Conners' Parent Rating Scale(K-CPRS). They also completed neuropsychological tests and assessed language profiles. Patients were categorized into two groups(with ADHD and without ADHD). T-test and Multivariate analysis of covariance (MANCOVA) was used for analysis. RESULTS: Statistically, no difference was found in receptive and expressive language ability between the ASD groups with and without ADHD. However, a lower score in Test of Problem solving(TOPS) was observed for ASD with ADHD than for ASD without ADHD, with problem solving and finding cues showing significant differences. CONCLUSIONS: These findings suggest that language profiles in the ASD group without ADHD could be similar to those in the ASD group with ADHD, but comorbid ADHD could lead to more difficulty in linguistic ability for problem solving and could be related with executive function of the frontal lobe.

Tumor heterogeneity of triple-negative breast cancer (TNBC) has been the main barrier in conquering breast cancer. To dissect the molecular diversity of TNBC and discover therapeutic targets for TNBC, the molecular classification of TNBC is a prioritized issue in research area. Accordingly, recent studies have been successful in classifying TNBC into several distinct subtypes with specific biologic pathways. Despite the different methodologies used and varied number of final subtypes, these studies identically suggested that TNBC consists of four major subtypes: basal-like, mesenchymal, luminal androgen receptor, and immune-enriched. By reviewing these methods of classifications of TNBC, we highlight the unmet need to develop a molecular classifier suited for TNBC.

OBJECTIVES: The deficit of recognition memory has been found as one of the common neurocognitive impairments in patients with schizophrenia. In addition, they were reported to fail to enhance the memory about emotional stimuli. Previous studies have shown that bilateral eye movements enhance the memory retrieval. Therefore, this study was conducted in order to investigate the memory enhancement of bilaterally alternating eye movements in schizophrenic patients. METHODS: Twenty one patients with schizophrenia participated in this study. The participants learned faces (angry or neutral faces), and then performed a recognition memory task in relation to the faces after bilateral eye movements and central fixation. Recognition accuracy, response bias, and mean response time to hits were compared and analysed. Two-way repeated measure analysis of variance was performed for statistical analysis. RESULTS: There was a significant effect of bilateral eye movements condition in mean response time(F=5.812, p<0.05) and response bias(F=10.366, p<0.01). Statistically significant interaction effects were not observed between eye movement condition and face emotion type. CONCLUSIONS: Irrespective of the emotional difference of facial stimuli, recognition memory processing was more enhanced after bilateral eye movements in patients with schizophrenia. Further study will be needed to investigate the underlying neural mechanism of bilateral eye movements-induced memory enhancement in patients with schizophrenia.

Currently, a variety of Information and Communication Technology(ICT) is being broadly utilized for mental health. Especially, mobile application is one of the effective ICT, and several applications have been developed after the spread of smartphones. The mobile-based mental health has several strengths, such as better treatment accessibility and easier check-ups of symptoms or daily activities by real-time monitoring. Better follow-ups of treatment course, more customized feedback and better transportability enable patients to be more adherent. However, there are some limitations of mobile technology about the mental health, such as technical troubles of electric errors, data safety problems and personal information extrusion. Therefore, full considerations should be given during the development and provision of the technology. Most of all, mental health specialists should actively participate in the development process by incorporation of evidence-based experiences and assurance of good clinical qualities.
