RESUMO
Objective@#Subjective cognitive decline (SCD) refers to self-reported memory loss despite normal cognitive function and is considered a preclinical stage of Alzheimer’s disease. This study aimed to examine the mediating effects of depression and Instrumental Activities of Daily Living (IADL) on the association between the scoring of Clinical Dementia Rating Scale-Sum of Boxes (CDR-SB) and Subjective Cognitive Decline Questionnaire (SCD-Q). @*Methods@#A sample of 139 community-dwelling older adults aged 65–79 with normal cognitive function completed the SCD-Q, a comprehensive neuropsychological battery, and functional/psychiatric scales. We conducted 1) a correlation analysis between SCD-Q scores and other variables and 2) a path analysis to examine the mediating effects of depression and IADL on the relationship between CDR-SB and SCD-Q. @*Results@#CDR-SB was found to be indirectly associated with SCD-Q, with depressive symptoms mediating this relationship. However, no direct association was observed between SCD-Q and CDR-SB. Additionally, IADL was not associated with SCD-Q and did not mediate the relationship between CDR-SB and SCD-Q. The model fit was acceptable (minimum discrepancy function by degrees of freedom divided [CMIN/DF]=1.585, root mean square error of approximation [RMSEA]=0.065, comparative fit index [CFI]=0.955, Tucker-Lewis index [TLI]=0.939). @*Conclusion@#Our results suggest that SCD-Q is influenced by depressive symptoms, but not by IADL. The role of depressive symptoms as a mediator between CDR-SB and SCD-Q indicates that psychological factors may contribute to the perception of SCD. Therefore, interventions targeting depression may mitigate the concerns associated with SCD and reduce feelings of worse performance compared to others of the same age group.
RESUMO
Objective@#This study aimed to assess the usefulness of a memory complaint questionnaire for predicting amyloid PET positivity in community-dwelling older adults. @*Methods@#We recruited community-dwelling older adults without history of dementia who wished to participate in the study based on voluntary consent. We performed the Seoul Neuropsychological Screening Battery-Core (SNSB-C), Memory Age-associated Complaint Questionnaire (MACQ), Apolipoprotein E (ApoE) genotyping, and amyloid PET. According to the result ofthe SNSB-C, participants with objective cognitive impairment were excluded, and finally 124 participants were included in thisstudy. We used receiver operating characteristic (ROC) curve and calculated area under the ROC curve (AUC) to evaluate usefulness of the MACQ compared to the result of ApoE genotyping for predicting amyloid PET positivity in cognitively unimpaired community-dwelling older adults. @*Results@#The mean age of the study participants was 73.3 years, and 69.4% were female. ROC curve with MACQ score and with ApoE4 carrier was created and AUC of each model was calculated. AUC value was 0.660 for MACQ score, and 0.695 for ApoE4 carrier. There was no statistically significant difference in AUC value (p=0.494). @*Conclusion@#In community-dwelling older adults without objective cognitive decline, the memory complaint questionnaire― MACQ showed no significant difference with ApoE4 carrier for predicting amyloid PET positivity.
RESUMO
Objective@#This study aimed to investigate treatment effects of combination therapy of memantine and acetylcholinesterase inhibitors (AchEIs) compared with AchEIs alone on behavioral and psychological symptoms of dementia (BPSD) in patients with moderate Alzheimer’s dementia (AD). @*Methods@#This was a 12-week, double-blind, randomized, placebo-controlled trial. A total of 148 patients with moderate AD participated in this study. Mini-Mental State Examination, Neuropsychiatric Inventory (NPI), Clinician’s Interview-Based Impression of Change plus caregiver input, Gottfries–Bråne–Steen Scale, and Zarit Burden Interview were used as assessment scales. @*Results@#There were no significant differences in age, sex, or education between AChEIs alone and combination groups. The combination group showed significantly more improvement of NPI-disinhibition score (0.76±2.15) than the AChEIs alone group (-0.14±1.71) after 12 weeks. @*Conclusion@#Our findings suggest that the combination therapy of memantine and AchEIs might be a beneficial option for reducing disinhibition symptoms of patients with moderate AD compared with AchEIs alone. We believe that clinicians need to consider additional memantine treatment when patients with moderate AD complain disinhibition symptom. A larger clinical trial is needed to further determine the efficacy and advantages of such combination therapy of memantine and AchEIs for treating BPSD of patients with moderate AD.
RESUMO
Objectives@#South Korea has established four national dementia plans (NDPs). However, there have been few policy studies focusing on health services to improve the effectiveness of the NDPs. This study aimed to develop measures to raise the efficacy of medical care in NDP. @*Methods@#We classified the implementation policies of the 3rd NDP and the national dementia initiative according to the key objectives of the dementia policy of the Organisation for Economic Co-operation and Development. After investigating the progress, complementary policies were developed by reviewing the existing policy literature and exemplary cases in developed countries. @*Results@#The Community Dementia Reassurance Center should provide integrated services. To promote early screening, private medical services should be engaged. To provide post-diagnostic support, we propose a “Dementia Intensive Support Team” in hospitals. To care for severe cases of behavioral and psychological symptoms of dementia (BPSD), an “Intensive Care Unit for BPSD” is needed. It would be more effective for the various functions of the “Dementia Reassurance Hospital” to be implemented by various private medical institutions, rather than for all the functions to be implemented only by public long-term care hospitals. @*Conclusion@#Rather than carrying out all projects in the public domain, active use of private resources will increase the effectiveness and efficiency of the NDP.

RESUMO
Objectives@#Deliberate self-poisoning (DSP) is the most common suicide method and can be life-threatening. The purpose of this study was to investigate the factors related to the lethality of DSP and the characteristics of the adolescent group. @*Methods@#A retrospective study was conducted on patients who had visited an academic hospital’s regional emergency medical center between 2015 and 2018. The data reviewed through their medical records included sociodemographic factors, clinical variables, and psychiatric treatment. Four groups (Q1–Q4) were categorized by descriptive analysis using the risk-rescue rating scale. @*Results@#A total of 491 patients were enrolled in this study. This study showed that high lethality had statistically significant associations with male sex, older age, admitting suicidal intentions, and the use of herbicides for suicide. Logistic regression analyses showed a significant association between high-lethality and female [odds ratio (OR)=0.50, 95% confidence interval (CI)=0.30–0.81, p=0.01], non-psychiatric drugs (over-the-counter drug: OR=2.49, 95% CI=1.08–5.74, p=0.03; herbicide: OR=8.65, 95% CI=3.91–19.13, p<0.01), and denial of suicide intent (OR=0.28, 95% CI=0.15–0.55, p<0.01). @*Conclusion@#This study showed the clinical factors associated with the high lethality of DSP and suggested that efforts were needed to care for and thoroughly examine patients with DSP.
RESUMO
Objective@#The association between benzodiazepine use and the risk of cognitive impairment or dementia has been controversial. Our study aims to detect this association through a caseon-case method using the Korea Institute of Drug Safety & Risk Management-Korea adverse event reporting system database (KIDS-KD) between 2007 and 2016. @*Methods@#Cases were adverse event (AE)-pairs with suspected cognitive impairment or dementia. 10 non-cases were matched to each case on age and sex. Exposure was defined as use of benzodiazepines, including long-, intermediate-, and short-acting benzodiazepine. We conducted multivariable logistic regression analyses to estimate reporting odds ratios (ROR) and 95% confidence intervals (CI). @*Results@#Of the 1,086,584 AE-pairs, 887 cases were suspected AE-pairs of cognitive impairment or dementia, and 775,444 non-cases were selected. Benzodiazepine use was associated with increased AE-pairs of cognitive impairment or dementia when assessed using those with certain, probable, and/or possible in causality assessments (ROR=2.69, 95% CI=1.66–4.38). Higher ROR estimates were shown in female (2.33, 1.48–3.67) and in those with polypharmacy (2.20, 1.35–3.57). Dementia safety profiles were inconsistent across individual benzodiazepine components. @*Conclusion@#These results suggest the potentially increased association between benzodiazepine use and cognitive impairment or dementia in female and those with polypharmacy. Inconsistent safety profiles of benzodiazepine components should be further investigated.
RESUMO
Background@#and Purpose: The effect of the integrated program comprising cognitive training, art therapy, and music therapy has not been extensively studied in patients with Alzheimer's disease (AD). The present study investigated the effect of integrated cognitive intervention therapy on cognition, and activity of daily life (ADL), and mood in patients with mild to moderate AD. @*Methods@#In this study, the data of 59 patients who met the National Institute of Neurological and Communicative Disorders and Stroke-Alzheimer disease and Related Disorders Association (NINCDS-ADRDS) criteria of probable AD among those who registered at the Centenarian's Good Memory Program in Goyang from September 2014 to August 2019 were collected. We statistically analyzed the scores of Korean version of a Mini-Mental Status Examination (K-MMSE), Korean Dementia Screening Questionnaire-Cognition (KDSQ-C), Geriatric Depression Scale (GDS), Beck Anxiety Inventory (BAI), and Seoul-Instrumental Activities of Daily Living (S-IADL) of the same patients before and after the use of integrated cognitive intervention therapy. @*Results@#K-MMSE slightly increased from 18.7±4.5 to 19.7±5.0 (p<0.001) and KDSQ-C improved from 14.5±7.6 before therapy to 12.6±7.2 after therapy (p=0.001). Mean S-IADL score improved from 17.6±7.6 before therapy to 15.7±9.5 after therapy (p<0.001). Additionally, mean GDS score before the therapy was 5.6±3.5 that improved to 4.2±3.0 after the therapy (p<0.001).Mean BAI score decreased from 8.4±10.3 before therapy to 5.9±8.4 after therapy (p=0.001). @*Conclusions@#In conclusion, this study demonstrated the possibility that the use of an integrated cognitive therapy improved cognition, ADL, and mood (depression and anxiety) in patients with mild to moderate ADs.
RESUMO
OBJECTIVE: Empathy is important in the education of medical students. Many psychosocial variables are related to empathy. The aim of the study was to investigate the relationship between empathy and psychosocial factors such as burnout, personality, self-esteem, and resilience. METHODS: The participants completed a set of self-reporting questionnaires, including questions related to socio-demographic characteristics, the Korean edition of the Jefferson Scale of Empathy, student version (JSE-S-K), Maslach Burnout Inventory General Survey (MBI-GS), NEO Five-Factor Inventory (NEO-FFI), Rosenberg Self-esteem Scale (R-SES), and Connor-Davidson Resilience Scale (CD-RISC). Partial correlation and regression analyses were performed. RESULTS: In male students, there were positive correlations between JSE-S-K and R-SES (r=0.229, p=0.002); conscientiousness of the NEO-FFI (r=0.153, p=0.037) and negative correlations, specifically between JSE-S-K and depersonalization of MBI (r=-0.206, p=0.005). In female students, there was positive correlations between JSE-S-K and personal accomplishment of MBI (r=0.384, p=0.004). In the multiple regression model, the JSE-S-K was affected by conscientiousness of the NEO-FFI (adjusted R² =0.245, β=0.201, p=0.001); depersonalization, personal accomplishment of the MBI-GS (β=-0.188, p=0.001, β=0.143, p=0.017); R-SES (β=0.176, p=0.004); sex (β=0.117, p=0.029). CONCLUSION: The present findings suggested that conscientiousness, depersonalization, personal accomplishment, self-esteem and sex have an influence on empathy. Therefore, these must be considered in medical education and can be helpful to nurture more empathetic doctors.

OBJECTIVE: Fall is one of major causes of morbidity and mortality in the elderly. It is known that sleep is associated with quality of life in the elderly. Snoring is one of the factors affecting sleep quality. The aim of the study was to examine whether snoring affect fall in the community elderly. METHODS: This survey was performed as a part of the Korean Social Life, Health, and Aging Project, which studied the elderly living in Ganghwa-gun. Fall was defined as any history of fall in the last year through face-to-face interview. We examined the following variables: age, sex, snoring, insomnia, hypertension, diabetes, stroke, bone disease, vision problems, depression, alcohol intake, mini-mental state examination, and body mass index. The data was analyzed by multiple logistic regression to determine the association of fall with the risk factors. RESULTS: In the multivariate analysis of 516 participants, the adjusted odd ratios (95% confidence interval) of simple snoring affecting fall was 1.70 (1.10–2.63). In addition, sex (female), age, and diabetes were significantly predicted the fall. CONCLUSION: Our result suggested that snoring could be a risk factor of fall. A more comprehensive study of the relationship between snoring and fall is needed to improve the quality of life of the community elderly.

OBJECTIVE: This study determined whether cognitive behavioral therapy for insomnia (CBT-i) decreased the need for sleep medications and produced better treatment outcomes than pharmacotherapy alone. METHODS: We reviewed data from patients with insomnia in the outpatient clinic of a general hospital between 2009 and 2015. We compared 41 patients who received five sessions of CBT-i with 100 age- and sex-matched patients who received pharmacotherapy only. We evaluated the change in prescription for sleep (i.e., antidepressants, hypnotics, and others) between the first and last visits using repeated measures analysis of variance (ANOVA). Clinical global impressions and completion status at the last visit were assessed using the chisquare test. RESULTS: We found a significant decrease in the prescription rate and the dosage of hypnotics among patients who received CBT-i when compared with control patients. There was no significant change in the dosage of antidepressants between the two groups. Achievement of case closure was better in the CBT-i group at the trend level. Clinical global impression at the last visit was not significantly different. CONCLUSION: These results show that CBT-i reduces the need for hypnotics among insomnia patients. Our results indicate that CBT-i offers additional benefits beyond improving sleep characteristics and thus provides another reason for recommending CBT-i as a first-line treatment for insomnia.

BACKGROUND AND PURPOSE: Several studies have validated the clinical efficacy of computerized cognitive training applications. However, few studies have investigated the neural substrates of these training applications using simultaneous multimodal neuroimaging modalities. We aimed to determine the effectiveness of computerized cognitive training and corresponding neural substrates through a multimodal approach. METHODS: Ten patients with mild cognitive impairment (MCI), six patients with subjective memory impairment (SMI), and 10 normal controls received custom-developed computerized cognitive training in the memory clinic of a university hospital. All of the participants completed 24 sessions of computerized cognitive training, each lasting 40 minutes and performed twice weekly. They were assessed using neuropsychological tests (both computerized and conventional), electroencephalography, fluorodeoxyglucose positron-emission tomography (FDG-PET), volumetric magnetic resonance imaging (MRI), and diffusion-tensor imaging (DTI) at pre- and posttraining. RESULTS: The patients with MCI exhibited significant improvements in the trail-making test–black & white-B, and memory domain of the computerized cognitive assessment. Subjects with normal cognition exhibited significant improvements in scores in the language and attention-/psychomotor-speed domains. There were no significant changes in subjects with SMI. In the pre- and posttraining evaluations of the MCI group, FDG-PET showed focal activation in the left anterior insula and anterior cingulate after training. Volumetric MRI showed a focal increase in the cortical thickness in the rostral anterior cingulate. DTI revealed increased fractional anisotropy in several regions, including the anterior cingulate. CONCLUSIONS: The anterior cingulate and anterior insula, which are parts of the salience network, may be substrates for the improvements in cognitive function induced by computerized cognitive training.

OBJECTIVES: Firefighters frequently experience traumatic events, high-tension situations and shift work. Therefore, the prevalence of insomnia of firefighters is higher than one of general population. Not only does the quality of sleep affect the satisfaction of personal life, but it also influences their performance for the public's safety. We investigated which factors affect the quality of sleep of firefighters. METHODS: After personally delivering 120 questionnaires to 3 fire stations, the survey was conducted when the consents were signed. It inquired about alcohol use, smoking, shift work, sleep quality, depression, anxiety, and experience of traumatic events. We then divided the firefighting officers in two groups according to the quality of sleep and compared the variables examined to conduct the logistic regression analyses according to the results. RESULTS: The poor sleeper group reported a higher level of current alcohol consumption, depression, anxiety and experience of traumatic events. Logistic regression analyses showed that the current alcohol intake (Crude odds ratio=3.707, 95% confidence interval=1.288–10.672, p=0.015 ; Adjusted odds ratio=3.288, 95% confidence interval=1.011–10.694, p=0.048) has a significant effect on sleep quality. CONCLUSIONS: Current alcohol consumption, depression, anxiety and experience of traumatic events were respectively associated with sleep quality of firefighters. When all significant factors considered, the current alcohol use was the only statistically significant. To improve the quality of sleep for firefighters, it will be necessary to evaluate alcohol intake, educate the poor sleep quality caused by alcohol, and provide specific interventions to reduce consumption.

OBJECTIVES: Psychiatric staffs may experience excessive work stress, burnout, and reduced job satisfaction in clinical settings. This can increase chances of diminishing their overall working efficiency or having difficulty managing their own mental health. The purpose of this study was to investigate the effect of group mindfulness- based cognitive therapy(MBCT) on job stress, burnout, self-efficacy, resilience, and job satisfaction. METHODS: Twenty eight psychiatric staffs who agreed to participate in the study were included. Self-report questionnaires were used to measure job stress, burnout, resilience, self-efficacy, and job satisfaction. To examine the effects of group MBCT, the scores were compared before and after MBCT. RESULTS: Work stress and burnout scale scores were significantly decreased after group MBCT. Resilience, job satisfaction, and self-efficacy scale scores were significantly increased after group MBCT. CONCLUSIONS: In the current study, group MBCT for psychiatric staffs helped to reduce their work stress and burnout, and, as well, helped to improve resilience, self-efficacy, and job satisfaction. This suggests that, in mental health treatment settings, psychiatric staffs can improve their mental health through group MBCT. Improving mental health of psychiatric staff may also have a positive impact on their patients.

OBJECTIVE: Sleep disturbance is common in the elderly, which is result from multi-factorial causes encompassing socio-demographic, behavioral, and clinical factors. We aimed to identify factors associated with insomnia among the elderly in a rural community in South Korea, a country with a rapidly growing aged population. METHODS: This cross-sectional study used the data from the second wave of the Korean Social life, Health and Ageing Project, which is a cohort study of individuals living in a typical rural community in South Korea. Socio-demographic, behavioral, and clinical characteristics were obtained through face-to-face interviews. Various factors suspected to be associated with insomnia were compared between elderly participants with and without insomnia, and multiple logistic regression analyses were conducted to identify independent risk factors for insomnia. RESULTS: We found that 32.4% of 509 participants (72.8±7.7 years old) had insomnia. Female sex [odds ratio (OR)=2.19], low education level (OR=2.44), current smoking (OR=2.26), number of chronic diseases (OR=2.21 for 2–3 chronic diseases; OR=2.06 for 4 or more chronic diseases), and depression (OR=2.53) were independently associated with insomnia. CONCLUSION: We found that sex, education, chronic disease, and depression independently increase the risk of insomnia of the elderly in a Korean rural community. To overcome the elderly's insomnia, interventions should target modifiable factors such as depression. To promote active aging, longitudinal studies of factors associated with insomnia among the elderly should be performed in different regions and communities.

OBJECTIVES: Sleep disturbance is a very rapidly growing disease with aging. The purpose of this study was to investigate the prevalence of sleep disturbances and its predictive factors in a three-year cohort study of people aged 60 years and over in Korea. METHODS: In 2012 and 2014, we obtained data from a survey of the Korean Social Life, Health, and Aging Project. We asked participants if they had been diagnosed with stroke, myocardial infarction, angina pectoris, arthritis, pulmonary tuberculosis, asthma, cataract, glaucoma, hepatitis B, urinary incontinence, prostate hypertrophy, cancer, osteoporosis, hypertension, diabetes, hyperlipidemia, or metabolic syndrome. Cognitive function was assessed using the Mini-Mental State Examination for dementia screening in 2012, and depression was assessed using the Center for Epidemiologic Studies Depression Scale in 2012 and 2014. In 2015, a structured clinical interview for Axis I psychiatric disorders was administered to 235 people, and sleep disturbance was assessed using the Pittsburgh Sleep Quality Index. The perceived stress scale and the State-trait Anger Expression Inventory were also administered. Logistic regression analysis was used to predict sleep disturbance by gender, age, education, depression score, number of coexisting diseases in 2012 and 2014, current anger score, and perceived stress score. RESULTS: Twenty-seven percent of the participants had sleep disturbances. Logistic regression analysis showed that the number of medical diseases three years ago, the depression score one year ago, and the current perceived stress significantly predicted sleep disturbances. CONCLUSION: Comorbid medical disease three years previous and depressive symptoms evaluated one year previous were predictive of current sleep disturbances. Further studies are needed to determine whether treatment of medical disease and depressive symptoms can improve sleep disturbances.

Emphysematous pyelonephritis (EPN) is a necrotizing infection of the kidney with gas formation that can be fatal if it is not detected and treated promptly. Typical manifestations are high fever, flank pain, and shock. It typically occurs in patients with diabetes and, although rarely reported, in hemodialysis (HD) patients with or without diabetes. Furthermore, asymptomatic EPN has not yet been reported in HD patients. Here, we report a case of asymptomatic EPN in a diabetic HD patient incidentally detected with follow-up abdominal computed tomography after resection of colon cancer.

BACKGROUND/AIMS: The aim of this study was to evaluate the efficacy of high definition (HD) i-SCAN for colorectal polyp detection in screening colonoscopy. METHODS: We retrospectively analyzed the records of 501 patients who had undergone screening colonoscopy performed by three endoscopists with either HD i-SCAN (n=149) or standard white light (n=352) from January 2, 2014 through June 30, 2014. Patient information and inter-endoscopist variation as well as polyp number, endoscopic findings, and pathologic characteristics were reviewed. RESULTS: The detection rates of colorectal and neoplastic polyps were significantly higher using HD i-SCAN than standard white light colonoscopy (52% vs. 38.1%, p=0.004 for colorectal polyps; and 37.2% vs. 27.9%, p=0.041 for neoplastic polyps). Analysis of endoscopic findings revealed no difference in detected polyp size between HD i-SCAN and standard white light colonoscopy (4.59+/-2.35 mm vs. 4.82+/-2.81 mm, p=0.739), but non-protruding polyps were more commonly detected by i-SCAN than by standard white light colonoscopy (24.6% vs. 13.5%, p=0.007). CONCLUSIONS: Colonoscopy using HD i-SCAN had a significantly higher detection rate of colorectal polyps, including neoplastic polyps, because of improved sensitivity for detecting non-protruding lesions.

Diagnoses of pyelonephritis caused by Staphylococcus aureus should be accompanied by investigations of concomitant bladder obstruction and metastatic infections, especially to the spine or heart. Complicated pyelonephritis due to S. aureus requires more than 2 weeks of antibiotics, which is the typically recommended treatment duration for pyelonephritis. We describe a patient who was diagnosed with complicated epidural and paraspinal abscesses after insufficient evaluation and treatment of acute pyelonephritis due to S. aureus. A 62-year-old man with type 2 diabetes was admitted with fever, increased urinary frequency, and left flank pain. He was diagnosed with acute pyelonephritis caused by S. aureus. His fever and flank pain subsided after 3 days of intravenous antibiotics. Evaluation of bladder obstruction and metastatic infection were not performed, as he declined further evaluation. The patient was discharged with oral antibiotics and was requested to attend weekly appointments but was lost to follow-up. One month later, the patient presented at the outpatient clinic with similar symptoms. Computed tomography showed recurrent pyelonephritis and a distended bladder. His flank pain persisted despite administration of an opioid agent. Therefore, magnetic resonance imaging was performed, revealing epidural and paraspinal abscesses. Ultrasound-guided aspiration of the paraspinal muscle layer was performed, and blood and percutaneous aspirated fluid cultures revealed S. aureus growth. The pattern of antimicrobial sensitivity was identical to that at his first admission. Following more than 4 weeks of antibiotics, magnetic resonance imaging showed the abscesses had decreased in size. The patient was discharged without neurologic sequelae and was provided with oral antibiotics.
