Occupational and Psychological Factors Associated With Burnout in Night Shift Nurses

Objective@#Providing inpatient nursing care inevitably involves night shift work. However, night shift work nurses often face psychiatric health problems such as burnout. If night shift work is an essential work type for nurses, it is necessary to select personnel suitable for night shift work or establish improvement measures such as psychiatric intervention through psychiatric evaluation. The objective of this study was to identify factors that could be interventional among factors affecting burnout in shift-working nurses. @*Methods@#A total of 231 night shift female nurses participated in this study. A questionnaire survey was given to assess their general characteristics. To assess burnout, the Maslach Burnout Inventory–General Survey Korean version was adopted. In addition, several mental health scales were used to identify individual psychological characteristics. To identify variables associated with the presence of burnout, odds ratios were calculated using a logistic regression model taking three dimensions of burnout as a dependent variable after adjusting for psychological and occupational factors. @*Results@#High resilience was a significant preventive factor in the three dimensions of burnout. Regarding occupational factor, the longer the duration of employment, the higher depersonalization, but the professional efficacy was good. @*Conclusion@#Our results indicate that resilience and social support could be prevention factors for burnout. This study is meaningful in examining items that require active intervention and support for burnout targeting night shift nurses who are indispensable for patient care.

Loss of Acquired Skills: Regression in Young Children With Autism Spectrum Disorders

Objectives@#Regression, while not a core symptom of autism spectrum disorder (ASD), has been suggested to be a distinct subtype by previous studies. Therefore, this study aimed to explore the prevalence and clinical differences between those with and without regression in children with ASD. @*Methods@#This study includes data from toddlers and young children aged 2–7 years acquired from other projects at Seoul National University Bundang Hospital. The presence and characteristics of regression were explored using question items #11–28 from the Autism Diagnostic Interview-Revised. Chi-square and independent t-tests were used to compare various clinical measurements such as autistic symptoms, adaptative behavior, intelligence, and perinatal factors. @*Results@#Data from 1438 young children (1020 with ASD) were analyzed. The overall prevalence rate of regression, which was mainly related to language-related skills, was 10.2% in the ASD group, with an onset age of 24 months. Regarding clinical characteristics, patients with ASD and regression experienced ASD symptoms, especially restricted and repetitive interests and behaviors, with greater severity than those without regression. Furthermore, there were significant associations between regression and hypertension/placenta previa. @*Conclusion@#In-depth surveillance and proactive interventions targeted at young children with ASD and regression should focus on autistic symptoms and other areas of functioning.

Patterns of Restricted and Repetitive Behaviors in Toddlers and Young Children with Autism Spectrum Disorder

Objectives@#Restricted and repetitive behaviors (RRBs) are a core symptom in the diagnosis of autism spectrum disorder (ASD). The complexity of behavioral patterns has called for the creation of phenotypically homogeneous subgroups among individuals with ASD.The purpose of this study was 1) to investigate the different types of RRBs and 2) to explore whether subgroups created by RRBs would show unique levels of functioning in toddlers and young children with ASD. @*Methods@#A total of 313 children with ASD, aged 12–42 months were included in the analysis. The Autism Diagnostic Interview-Revised was used to obtain information on the different types of RRBs by grouping 15 items into six categories. The Vineland Adaptive Behaviors Scale, a parent-reported questionnaire, was used to measure adaptive functioning. A portion of the children were analyzed separately for verbal-related RRBs based on their expressive language level. Two-step cluster analysis using RRB groups as features was used to create subgroups. Analysis of covariance while covarying for age and language was performed to explore the clinical characteristics of each cluster group. @*Results@#Sensory-related RRBs were the most prevalent, followed by circumscribed interests, interest in objects, resistance to change, and repetitive body movements. A subset of the children was analyzed separately to explore verbal-related RRBs. Four cluster groups were created based on reported RRBs, with multiple RRBs demonstrating significant delays in adaptive functioning. @*Conclusion@#Heterogeneity of RRBs emerges at a young age. The different patterns of RRBs can be used as valuable information to determine developmental trajectories with better implications for treatment approaches.

Validation of Social Responsiveness Scale for Korean Preschool Children With Autism

Objective@#This cross-cultural study aims to examine the psychometric properties of the Social Responsiveness Scale (SRS) and to determine the best-estimate-cut-off scores for the diagnosis of autism spectrum disorder (ASD) in Korean preschool children. @*Methods@#A total of 563 children was recruited from multiple sources, including Seoul National University Bundang Hospital. Participants were assessed by a multidisciplinary research team using multiple diagnostic tools based on DSM-5 diagnostic criteria. Discriminative validity was tested by comparing the difference in SRS scores between ASD and non-ASD groups. Convergent validity was tested by examining correlations between SRS scores with other diagnostic instruments. A receiver operation characteristic curve analysis was conducted to test the sensitivity and specificity of SRS and to determine the best-estimate-cut-off scores for screening ASD in Korean preschool children. @*Results@#There were significant differences in the total SRS scores between the ASD (n=242) and non-ASD group (n=321) (p<0.01, 95% confidence interval [CI]: 14.08–17.24). The differences were significant even after adjusting for age. SRS scores were significantly correlated with other prescreening diagnostic tools for ASD. The best-estimate cut-off score to screen ASD was 55 (area under curve=0.88, sensitivity 78.1%, specificity 86.6%). @*Conclusion@#The SRS is a valid and reliable instrument to screen and aid in the diagnosis of ASD in Korean preschool children. The adjusted cut-off scores, notably lower than in the original U.S. version, may yield a more accurate diagnosis by reflecting transcultural differences.

Meteorological Factors Associated with the Number of Emergency Room Patients with Wrist-Cutting Behavior / 정신신체의학

Objectives@#：Although the seasonality of suicide is a well-known phenomenon, little is reported about the seasonality of non-suicidal self-injury. The purpose of this study was to identify the seasonality of wristcutting behavior and to examine its relationship with meteorological factors. @*Methods@#：To identify the presence of seasonality, we investigated whether there was a difference in the average number of visits per month to an emergency room (ER) of an urban hospital for 226 patients with wrist-cutting behavior enrolled between December 2014 and May 2019. To ascertain significant meteorological factors, we used the multiple Poisson regression using generalized additive model with time, monthly temperature, monthly sunshine hour, and atmospheric pressure in the prior month as explanatory variables. @*Results@#：In males, the average number of monthly visits to the ER for wrist cutting behavior differed by month and was the highest in September (male : p=0.048, female : p=0.21, total : p=0.28). As a result of multiple regression analysis, the average number of patients admitted to the ER for wrist cutting behavior was related to the interaction between atmospheric pressure in the prior month and temperature in males (p=0.010), and showed a positive correlation with sunlight in females [p=0.044 , β=4.70×10-3 , 95% CI=(1.19×10-4 , 9.27×10-3 )]. @*Conclusions@#：Wrist cutting behavior shows seasonality in male, which is associated with changes in meteorological variables.

Analysis of risk factors for portal vein thrombosis after liver resection

PURPOSE: We evaluated the risk factors for posthepatectomy thrombosis including portal vein thrombosis (PVT) and clinical outcomes. METHODS: We retrospectively analyzed 563 patients who had undergone hepatectomy from February 2009 to December 2014. Twenty-nine patients with preoperatively confirmed thrombosis and tumor recurrence-related thrombosis were excluded. We identified the location of the thrombosis as main portal vein (MPV), peripheral portal vein (PPV) and other site such as hepatic vein or inferior vena cava. Patients with MPV thrombosis and PPV thrombosis with main portal flow disturbance were treated with anticoagulation therapy. We performed operative thrombectomy before anticoagulation therapy who did combined portal vein (PV) segmental resection. RESULTS: Of the 534 patients, 22 (4.1%) developed posthepatectomy thrombosis after hepatectomy. Among them, 19 (86.4%) had PVT. The mean duration of Pringle's maneuver was significant longer in the PVT group than the no-thrombosis group (P = 0.020). Patients who underwent combined PV segmental resection during hepatectomy were more likely to develop posthepatectomy PVT (P = 0.001). Thirteen patients who had MPV thrombosis and PPV thrombosis with main portal flow disturbance received anticoagulation therapy immediately after diagnosis and all of them were improved. Among them, 2 patients who developed PVT at the PV anastomosis site after PV segmental resection, underwent operative thrombectomy before anticoagulation therapy and both were improved. There were no patients who developed complications related to anticoagulation therapy. CONCLUSION: Long duration of Pringle's maneuver and PV segmental resection were risk factors. Anticoagulation therapy or operative thrombectomy should be considered for PVT without contraindications.

Clinical characteristics of intentional self-harm inpatient with lethal methods

OBJECTIVE: The aim of this study was to identify the latent class, according to the risk factors, of the patients hospitalized due to intentional self-harm by lethal means. METHODS: The risk factors were derived by categorizing the intentional self-harming measures by lethal (hanging, pesticide poisoning, jumping, and drowning) and non-lethal (drug poisoning and stab) measures and comparing the demographics, diseased state, and suicide-related characteristics. Latent class analysis was performed to identify the type of intentional self-harm. RESULTS: Male (sex), elderly (age), rural (residing location), and comorbid diseases were found to be the risk factors for fatal injuries. For this, four latent classes were modeled. Factors, such as the age group between 20 to 40 years, women, and family conflict were included in the first class. The second class included the age group between 30 to 50 years, men, and financial problems. The third class covered the age group between 60 to 70 years and comorbidity. The fourth class contained the age group of 10 to 50 years, women, and mental problems. The rate of suicide and choice of fatal suicide was ranked in the order of 3 (62.7%, 21.5%), 2 (59.8%, 13.9%), 4 (36.8%, 5.7%), and 1 (29.5%, 5.9%). CONCLUSION: A lethal mean access control policy needs to be established for the high-risk group of self-harm. Moreover, establishing an emergency room-community link prevention policy could help reduce the re-suicide attempt among suffering patients.

The Association of Plasma Inflammatory Cytokines with Dementia and Mild Cognitive Impairment / 생물치료정신의학

OBJECTIVES: The aim of this study was to investigate the association of plasma levels of inflammatory cytokines with dementia and mild cognitive impairment.METHODS: We compared serum levels of tumor necrosis factor-alpha(TNF-alpha), interleukin-6(IL-6), and insulin-like growth factor-1(IGF-I) in patients with dementia(n=8), mild cognitive impairment(MCI, n=15) and normal elderly (n=14). The diagnosis of dementia was made by the Diagnostic Statistical Manual of Mental Disorders-4th edition (DSM-IV). MCI was diagnosed based on the criteria of the National Institute of Aging and Alzheimer Association(NIA-AA) working group.RESULTS: When compared with normal controls, the levels of TNF-alpha and IL-6 were increased and level of IGF-I was decreased in MCI and dementia. Higher levels of TNF-alpha and IL-6 and lower level of IGF-I were also associated with increased age. However, when adjusted for age, the association between diagnosis and TNF-alpha, Il-6 and IGF-I was not significant.CONCLUSION: The difference in plasma levels of inflammatory cytokines in dementia and MCI may be associated with aging.

Clinical outcome of 1,000 consecutive cases of liver transplantation: a single center experience

PURPOSE: The aim of this study was to analyze survival outcomes in 1,000 consecutive liver transplantations (LTs) performed at a single institution from 1993 to April 2017. METHODS: The study population was divided into 2 groups based on donor type: deceased donor LT (DDLT; n = 181, 18.1%) and living donor LT (LDLT; n = 819; 81.9%), and into 3 periods based on the number of cases (first 300 cases, middle 300 cases, last 400 cases). RESULTS: Infection was the most common cause of death, accounting for 34.8% (95 of 273). Mortality due to hepatocellular carcinoma recurrence occurred most frequently between 1 and 5 years after transplantation. Mortality rate by graft rejection was highest between 5 and 10 years after transplantation. And mortality by de novo malignancy occurred most frequently after 10 years after transplantation. The patient survival rates for the entire population at 5 and 10 years were 74.7%, and 68.6%, respectively. There was no difference in survival rate between the LDLT and DDLT groups (P = 0.188). Cause of disease, disease severity, case period, and retransplantation had a significant association with patient survival (P = 0.002, P = 0.031, P = 0.003, and P = 0.024, respectively). CONCLUSION: Surgical techniques and perioperative management for transplant patients have improved and undergone standardization. Controlling perioperative infection and managing patients with HCC as LT candidates will result in better outcomes.

Association between Impulsivity and Medical Lethality of Suicide Attempts among Suicide Attempters

OBJECTIVES: Although impulsivity has long been thought as an important factor influencing suicidal behaviors, it is unknown whether impulsivity increases the risk of dying from suicidal behaviors and what specific component among constructs of impulsivity contributes to the risk of dying among suicide attempters. METHODS: To elucidate the association between impulsivity and medical lethality of suicide attempt among suicide attempters, we consecutively recruited 46 suicide attempters who visited an emergency room of a general hospital located in a metropolitan area, Seoul, Republic of Korea, due to suicide attempts and consented to participate in this study. Then we assessed medical lethality with the Beck Lethality Scale (LS) and impulsivity with the Korean version of the Barratt Impulsiveness Scale-11-Revised (BIS). Demographic variables were obtained from medical records and structured social work reports for suicide attempters. RESULTS: Although total scores of the BIS did not correlate with LS scores, only the scores of self-control, that is one of the Barret's six theoretical constructs of impulsivity in which the higher score indicates less self-control and more impulsivity, had a significant positive correlation with scores of LS (p = 0.003). The association remained significant after adjusting for variables known to affect suicide lethality such as job status, recent alcohol consumption, diagnosis of depressive disorders, and having a plan for suicide (β = 0.429, p = 0.009). CONCLUSIONS: Not impulsivity in general, but poor self-control, in particular, predicts lethal suicidal behaviors among suicide attempters. The degree of self-control should be evaluated when assessing patients with elevated suicide risk, and proper measures should be installed to prevent possible future lethal suicide attempts.

Effects of splanchnic vasoconstrictors on liver regeneration and survival after 90% rat hepatectomy

PURPOSE: Posthepatectomy liver failure is a serious complication and considered to be caused by increased portal pressure and flow. Splanchnic vasoactive agents and propranolol are known to decrease portal pressure. The aim of this study was to identify optimal candidates with potential for clinical use among somatostatin, terlipressin, and propranolol using rats with 90% hepatectomy. METHODS: Rats were divided into 5 groups: sham operation (n = 6), control (n = 20), propranolol (n = 20), somatostatin (n = 20), and terlipressin group (n = 20). Seven-day survival rates and portal pressure change were measured, and biochemical, histologic, and molecular analyses were performed. RESULTS: Portal pressure was significantly decreased in all 3 treatment groups compared to control. All treatment groups showed a tendency of decreased liver injury markers, and somatostatin showed the most prominent effect at 24 hours postoperatively. Histologic liver injury at 24 hours was significantly decreased in propranolol and terlipressin groups (P = 0.016, respectively) and somatostatin group showed borderline significance (P = 0.056). Hepatocyte proliferation was significantly increased after 24 hours in all treatment groups. Median survival was significantly increased in terlipressin group compared to control group (P < 0.01). CONCLUSION: Terlipressin is considered as the best candidate, while somatostatin has good potential for clinical use, considering their effects on portal pressure and subsequent decrease in liver injury and increase in liver regeneration.

Risk factors for cancer recurrence or death within 6 months after liver resection in patients with colorectal cancer liver metastasis

PURPOSE: The aim of this study was to find risk factors for early recurrence (ER) and early death (ED) after liver resection for colorectal cancer liver metastasis (CRCLM). METHODS: Between May 1990 and December 2011, 279 patients underwent liver resection for CRCLM at Korea University Medical Center. They were assigned to group ER (recurrence within 6 months after liver resection) or group NER (non-ER; no recurrence within 6 months after liver resection) and group ED (death within 6 months after liver resection) or group NED (alive > 6 months after liver resection). RESULTS: The ER group included 30 patients (10.8%) and the NER group included 247 patients (89.2%). The ED group included 18 patients (6.6%) and the NED group included 253 patients (93.4%). Prognostic factors for ER in a univariate analysis were poorly differentiated colorectal cancer (CRC), synchronous metastasis, ≥5 cm of liver mass, ≥50 ng/mL preoperative carcinoembryonic antigen level, positive liver resection margin, and surgery alone without perioperative chemotherapy. Prognostic factors for ED in a univariate analysis were poorly differentiated CRC, positive liver resection margin, and surgery alone without perioperative chemotherapy. Multivariate analysis showed that poorly differentiated CRC, ≥5-cm metastatic tumor size, positive liver resection margin, and surgery alone without perioperative chemotherapy were independent risk factors related to ER. For ED, poorly differentiated CRC, positive liver resection margin, and surgery alone without perioperative chemotherapy were risk factors in multivariate analysis. CONCLUSION: Complete liver resection with clear resection margin and perioperative chemotherapy should be carefully considered when patients have the following preoperative risk factors: metastatic tumor size ≥ 5 cm and poorly differentiated CRC.

Dual-incision laparoscopic spleen-preserving distal pancreatectomy

Laparoscopic spleen-preserving distal pancreatectomy has been widely performed for benign and borderline malignancy in the body or tail of the pancreas when there are not oncologic indications for splenectomy. As the need for minimally invasive procedures to reduce postoperative morbidity and improve the quality of life is increasing, many surgeons have attempted to reduce the number of trocars and incision size to minimize access trauma and scarring. Single-port laparoscopic spleen-preserving distal pancreatectomy is the result of these efforts; however it has many limitations such as technical difficulty and prolonged operation time. In this article, we report the first case of dual-incision laparoscopic spleen-preserving distal pancreatectomy, proving that it can be a safe and feasible minimally invasive procedure for benign or borderline malignant tumors in the body or tail of the pancreas.

Fifteen-year Experience with Telemedicine Services in Gangwon Province in Korea / 대한의료정보학회지

OBJECTIVES: This study attempted to identify the factors that contribute to successful telemedicine service. This was done by analyzing the operational state of successful telemedicine services offered in Gangwon Province of Korea and their outcome for the last fifteen years. METHODS: A comparative analysis was made based on reports and a thesis on the satisfaction rate of patients and providers, patient compliance to treatment, and economic assessment of Gangwon telemedicine service, which were carried out in three periods: the years 2006, 2010, and 2012. RESULTS: The satisfaction surveys in all three periods showed similar results for patients (4.46+/-0.70 point) and healthcare practitioners, including nurses (3.82+/-0.62 point) and physicians (3.60+/-0.56 point), in decreasing order from the year 2012. Through the survey of patients' compliance with treatment, it was confirmed that telemedicine services increased patients' compliance with drug administration, facilitated improvement of lifestyle habits, improved glycated hemoglobin for patients with diabetes mellitus, and enhanced the rate of blood pressure control. In the survey conducted on patients' willingness to pay for telemedicine services in 2007, it was found that those patients were willing to pay about $3.5 for services. CONCLUSIONS: The telemedicine services of Gangwon Province increased patients' compliance with drug administration, improved blood glucose control, enhanced blood pressure control for patients with hypertension, and provided economic advantage.

De novo hepatitis B virus infection developing after liver transplantation using a graft positive for hepatitis B core antibody

PURPOSE: The use of hepatitis B core antibody (HBcAb)-positive grafts is increasing, especially where hepatitis B is endemic. However, this remains controversial because of the risk of development of de novo HBV infection. METHODS: We collected information obtained between January 2000 and December 2012 and retrospectively analyzed data on 187 HBsAg-negative donors and recipients were analyzed retrospectively. De novo HBV infection was defined as development of HBsAg positivity with or without detection of HBV DNA. RESULTS: Forty patients (21.4%) received HBcAb-positive grafts. Survival rate did not differ by donor HBcAb status (P = 0.466). De novo HBV infection occurred in five patients (12.5%) who were not treated with anti-HBV prophylaxis, and was significantly more prevalent in hepatitis B surface antibody (HBsAb)- and HBcAb-negative than HBsAb- and HBcAb-positive recipients (50% vs. 4.2%, P = 0.049). All patients except one were treated with entecavir with/without antihepatitis B immunoglobulin and four were negative in terms of HBV DNA seroconversion. No patient died. CONCLUSION: HBcAb-positive grafts are safe without survival difference. However, the risk of de novo hepatitis B virus infection was significantly increased in HBsAb- and HBcAb-negative recipients. All patients were successfully treated even after recurrence.

Effects of glucose concentration in the medium on rat hepatocyte culture

PURPOSE: To determine the optimum culture conditions by investigating isolated rat hepatocytes cultured in medium containing different glucose concentrations. METHODS: Hepatocytes were isolated from rats using a two-step perfusion technique and divided into the following two groups cultured in medium containing different glucose concentrations: (1) low-glucose group and (2) high-glucose group. Total cell count and viability of cultured rat hepatocytes and liver function parameters (i.e., concentrations of albumin, ammonia, and urea in the culture medium) were measured. The morphology of cultured rat hepatocytes was examined by staining with hematoxylin and eosin, and albumin receptor expression was confirmed by immunofluorescence. RESULTS: Total cell count and viability showed smaller increases in the low-glucose group than the high-glucose group, although the difference was not statistically significant (P = 0.112 and P = 0.147, respectively). The levels of albumin (P = 0.943), ammonia (P = 0.744), and urea (P = 0.709) were not significantly different between the two groups. In both groups, the function of cultured hepatocytes decreased significantly over time. The morphology of hepatocytes was well maintained in both groups at 3 days. On day 7, the cytoplasm was transformed into a spindle shape. On day 10, these changes were exaggerated, and were more prominent in the high-glucose group. CONCLUSION: Morphological assessment indicated that low-glucose culture medium is better than high-glucose culture medium for culturing of hepatocytes, although there was not significantly different in functional assessment. The cultured hepatocytes with low-glucose culture medium could be maintained for 7 days.

Tangalle Sri Lanka Emergency Medical Center: To Implement a New Operating and Management System Through Means of Surveys

PURPOSE: This study was conducted in the base hospital of Tangalle, Sri Lanka, in order to improve a new emergency operating system. METHODS: Emergency staff and patients were surveyed based on the five point Likert scale. Doctors and nurses were asked to rate their level of satisfaction regarding their relationship with patients. Patients were asked to rate their level of satisfaction with doctors, facilities, and the environment in the hospital. RESULTS: Doctors were overall satisfied with their job, scoring an average of 3.7. They were displeased with limitation of autonomous decision making on medical treatment, which they gave a score of 2.80. Nurses were generally satisfied with emergency services, with a score of 4.53. Nurses feel discomfort in non-specialized training (3.02). They also sense a lack of opportunities in their hospital (3.12). Patients' findings indicate that most patients were satisfied (4.2) and were displeased with wait time (3.429) and the attention that was given to each patient (3.92). When asked if they would recommend their physician to others and were willing to come back to their physician, outcomes were generally positive, receiving scores of 4.1, respectively. CONCLUSION: Findings showed that in order to create a well-structured system in the emergency centers around the Tangalle area, it is crucial to meet the needs of both patients and the emergency staff. Patients must have a sense of rapid treatment as well as privacy. Training should be provided to the staff so that they are better informed in quality care and up to date on recent studies.

Outcomes of living donor liver transplantation using elderly donors

PURPOSE: Living donor liver transplantation (LDLT) using elderly donors is increasing in frequency in response to organ shortage. However, elderly donor graft has been reported to negatively affect graft patency and patient survival. METHODS: We retrospectively reviewed the medical records of 604 patients who underwent LDLT at Seoul St. Mary's Hospital, The Catholic University of Korea between May 1999 and September 2012. Elderly donors were defined as those > or =55 years of age. Here, we evaluate the survival differences and causes of death of recipients of elderly donor grafts. RESULTS: The overall mortality rate of the recipients was significantly higher in the elderly donor group (group A) than in the younger donor group (group B: 46.2% vs. 18.1%, P = 0.004). The survival length of group A was significantly shorter than that of group B (31.2 +/- 31.3 and 51.4 +/- 40.8 months, P = 0.014). The significantly common causes of death in group A were biliary (41.7%) and arterial complication (16.7%), and it was higher than those in group B (P = 0.000 and P = 0.043, respectively). CONCLUSION: LDLT using elderly donors could induce more serious complications and higher mortality rates than those at using younger donors. As such, careful donor selection is needed, especially with regard to assessing the condition of potential elderly donor livers. Furthermore, a large-volume and multicenter study of complications and outcomes of LDLT using elderly donor liver is required.
