ABSTRACT

Objective: We conducted a descriptive analysis of multi-drug resistant tuberculosis (MDR-TB) in Vietnam's two largest cities, Hanoi and Ho Chi Minh city. Methods: All patients with rifampicin resistant tuberculosis were recruited from Hanoi and surrounding provinces between 2020 and 2022. Additional patients were recruited from Ho Chi Minh city over the same time period. Demographic data were recorded from all patients, and samples collected, cultured, whole genome sequenced and analysed for drug resistance mutations. Genomic susceptibility predictions were made on the basis of the World Health Organization's catalogue of mutations in Mycobacterium tuberculosis associated with drug resistance, version 2. Comparisons were made against phenotypic drug susceptibility test results where these were available. Multivariable logistic regression was used to assess risk factors for previous episodes of tuberculosis. Results: 233/265 sequenced isolates were of sufficient quality for analysis, 146 (63 %) from Ho Chi Minh City and 87 (37 %) from Hanoi. 198 (85 %) were lineage 2, 20 (9 %) were lineage 4, and 15 (6 %) were lineage 1. 17/211 (8 %) for whom HIV status was known were infected, and 109/214 (51 %) patients had had a previous episode of tuberculosis. The main risk factor for a previous episode was HIV infection (odds ratio 5.1 (95 % confidence interval 1.3-20.0); p = 0.021). Sensitivity for predicting first-line drug resistance from whole genome sequencing data was over 90 %, with the exception of pyrazinamide (85 %). For moxifloxacin and amikacin it was 50 % or less. Among rifampicin-resistant isolates, prevalence of resistance to each non-first-line drug was < 20 %. Conclusions: Drug resistance among most MDR-TB strains in Vietnam's two largest cities is confined largely to first-line drugs. Living with HIV is the main risk factor among patients with MDR-TB for having had a previous episode of tuberculosis.

ABSTRACT

We characterized the spatial distribution of drug-susceptible (DS) and multidrug-resistant (MDR) tuberculosis (TB) cases in Ho Chi Minh City, Vietnam, a major metropolis in southeastern Asia, and explored demographic and socioeconomic factors associated with local TB burden. Hot spots of DS and MDR TB incidence were observed in the central parts of Ho Chi Minh City, and substantial heterogeneity was observed across wards. Positive spatial autocorrelation was observed for both DS TB and MDR TB. Ward-level TB incidence was associated with HIV prevalence and the male proportion of the population. No ward-level demographic and socioeconomic indicators were associated with MDR TB case count relative to total TB case count. Our findings might inform spatially targeted TB control strategies and provide insights for generating hypotheses about the nature of the relationship between DS and MDR TB in Ho Chi Minh City and the wider southeastern region of Asia.

ABSTRACT

Objectives@#:This study intends to assess the associations among perceived stigma at the time of infection, coping strategies adopted 12 months later and depressive and posttraumatic symptoms 24 months later in Middle Eastern Respiratory Syndrome (MERS) survivors. @*Methods@#:A nationwide cohort study was conducted on 63 survivors of 2015 MERS outbreak. Demographic data, illness severity of MERS, depression and posttraumatic stress symptoms, coping strategies and MERS-related stigma were collected 12 and 24 months after the MERS outbreak, respectively. @*Results@#:Higher levels of perceived stigma at the time of outbreak were associated with higher levels of dysfunctional coping strategies after 12 months (p=0.003) and more severe depressive (p=0.058) and posttraumatic stress symptoms (p=0.011) after 24 months. Moreover, higher levels of dysfunctional coping strategies after 12 months were significantly associated with more severe depressive (p=0.002) and posttraumatic stress symptoms (p<0.001) after 24 months. @*Conclusions@#:Social stigma against people who have contracted an emerging infectious disease can leave a negative impact on the mental health of the survivors in the long term. In case of novel pandemics in the future, promptrectification of stigma and promotion of adaptive coping strategies in survivors are needed.

ABSTRACT

Objective@#Among old adults, caring for a spouse with cognitive decline is well-known to be associated with significant risk to the caregiver’s health such as cardiovascular disease, depression and, especially, cognitive impairment. It is important to understand the caregiving-related risk factors for caregiver’s cognitive decline. Therefore, in this study, we examined the impact of caregiver’s burden on the modifiable lifestyle factors influencing cognitive decline among spousal caregivers (SCGs), focusing on nutritional status which contribute to SCG’s cognitive decline. @*Methods@#A total of 44 subjects were included in the analysis. As clinical assessment, we evaluated the care burden (Zarit Burden Interview), depression (Geriatric Depression Scale), sleep quality (Pittsburgh Sleep Quality Index), cognitive function (Mini-Mental State Examination, MMSE) physical activity (International Physical Activity Questionnaire), and nutritional status (Mini Nutritional Assessment). @*Results@#High Neuropsychiatric Inventory (NPI) score and low MMSE score were significantly correlated with increased care burden. The SCG’s caregiving burden was significantly associated with the risk of malnutrition and increased level of depressed mood. These significant relationships unchanged even after adjusting for care-recipient’s MMSE or NPI score. @*Conclusion@#This study provides substantial evidence that SCGs of cognitive impairment are at risk for depression and malnutrition, which can further affect cognitive decline. As such, these factors should be well assessed and monitored among SCGs for patient with cognitive impairment.

ABSTRACT

Objectives@#:To describe the differences in long-term outcomes in Alzheimer’s disease (AD) patients according to initial dementia severity. @*Methods@#:A retrospective chart review of AD patients from a dementia clinic at the University Hospital in Korea was conducted from April 2010 to March 2017. There were 168 patients enrolled, who were divided into three groups based on initial Clinical Dementing Rating (CDR). There were 55 in the very mild group (CDR=0.5 ; mean age 80.64±6.57), 93 in the mild group (CDR=1 ; mean age 80.57±7.28) and 20 in the moderate group (CDR=2 ; mean age 83.00±9.07). Participants were treated with donepezil±memantine. The observation period was 2.44±0.50 years. Cognitive function and severity of dementia were initially assessed by the Consortium to Establish a Registry for Alzheimer’s Disease Neuropsychological Assessment Battery (CERAD-NP) and were annually assessed by Mini-Mental State Exam (MMSE), CDR and CDR-Sum of boxes (CDR-SB). @*Results@#:The annual decline rate of MMSE score was -0.82 and those of very mild, mild, moderate groups were -0.63, -0.80, -1.96 respectively, while the annual change in CDR-SB score was 0.98, very mild group 0.86, mild group 1.03, moderate group 1.26. Education level, male, initial CDR were found to be significant potential factors in the annual change in MMSE, while initial CDR was a significant potential factor in the annual change in CDR-SB. @*Conclusion@#:It is meaningful that we studied long-term outcomes of anti-dementia medications in real-world clinical setting. The higher the initial severity of AD, the higher the cognitive decline rate.

ABSTRACT

Objective@#Cardiovascular diseases are representative risk factors for the onset of cognitive decline. The purpose of this study was to confirm the relationship between diastolic blood pressure and cognitive function in elderly people in Korea. @*Methods@#Data from subjects who were enrolled in the prospective Korean Longitudinal Study on Cognitive Aging and Dementia were used in this study. Data from 701 subjects whose diastolic blood pressure range did not change (≤79 mm Hg or ≥80 mm Hg) over 2 years were analyzed. To analyze the differences in cognitive function between the groups at the 2-year follow-up, an analysis of covariance was performed with covariates, which were significantly different between the two groups, and the baseline cognitive function. @*Results@#Significant differences were observed between the two groups, and the mean scores on the constructional praxis (η2=0.010) and word list recall tests (η2=0.018) in the diastolic blood pressure ≥80 mm Hg group were higher than those in the diastolic blood pressure ≤79 mm Hg group at the 2-year follow-up. @*Conclusion@#These results indicate that maintaining a DBP below 79 mm Hg presents a greater risk of cognitive decline in Korean elderly people.

ABSTRACT

Objective@#This study estimated the incidence of driving-related adverse events and examined the association of cognitive function with the risk of future driving-related adverse events in the elderly Korean male population. @*Methods@#We analyzed 1,172 male drivers aged 60 years or older in the Korean Longitudinal Study on Cognitive Aging and Dementia (KLOSCAD). Using the data from Korean National Police Agency, we classified the participants into three groups: safe driving (drove for 2 years after baseline without a traffic accident or repeated violations), driving cessation (stopped driving), and risky driving (one or more traffic accidents or repeated violations). We estimated the incidences of driving cessation and risky driving, and examined the effect of cognitive function on their risks. @*Results@#The incidence of driving cessation and risky driving in the Korean male drivers aged 60 years or older was 19.3 and 69.9 per 1,000 person-years respectively and increased in the late 80s. Drivers with better baseline Word List Memory Test scores showed less risky driving (OR=0.94, p=0.039). @*Conclusion@#Driving-related adverse events increased in late 80s, and better memory function was protective against these events.

ABSTRACT

Objective@#We investigated the frequency of depressive disorders in the elderly with normal cognition (NC), mild cognitive impairment (MCI) and dementia patients living in the community to find out the association between cognitive disorders and depressive disorders in the community dwelling elderly. @*Methods@#6,262 baseline study subjects from November 2010 through October 2012 were enrolled based on the Korean longitudinal study on cognitive aging and dementia which is the first nationwide multi-center population based prospective cohort study in Korea. Diagnosis of MCI, dementia, major depressive disorder (MDD), minor depressive disorder (mDD) and subsyndromal depression (SSD) was made by psychiatrists with expertise in dementia based on the appropriate diagnostic criteria. @*Results@#4,303 NC, 1,737 MCI, 222 dementia were enrolled. The frequency of MDD, mDD, SSD were highest in dementia and lowest in NC and showed significant difference among three groups. The odds ratio also increased significantly in MCI and dementia compared with NC showing highest odds ratio in dementia. @*Conclusion@#Our findings propose that MCI and dementia in the community dwelling elderly were significantly associated with various types of depressive disorders showing highest association tendency in dementia.

ABSTRACT

Nonelderly disabled Medicare beneficiaries have a higher prevalence of chronic conditions, higher utilization of prescription medications, and increased demand for clinical services when compared to beneficiaries 65 years of age and older who are not disabled. Out-of-pocket costs and medication-related problems are major barriers to medication compliance and achievement of therapeutic goals. A school of pharmacy partnered with a nonprofit organization that provides care to individuals with developmental disabilities. The present study highlights outcomes resulting from (a) providing Medicare Part D plan optimization services to lower prescription drug costs and (b) Medication Therapy Management services to evaluate safe and effective medication use in this beneficiary population. Provided interventions were shown to reduce overall medication costs and identify significant medication-related problems.

ABSTRACT

OBJECTIVE: The relationship among chronic fatigue, depressive symptoms, and post-traumatic stress symptoms (PTSSs) among Middle East respiratory syndrome (MERS) survivors is poorly understood. METHODS: Of 148 survivors who consented to be registered and underwent assessments at 12 months (T1) and 18 months (T2) after the MERS outbreak, 72 (48.65%) were evaluated for chronic fatigue, depressive symptoms, and PTSSs based on the Impact of Event ScaleRevised (IES-R), the Patient Health Questionnaire-9 (PHQ-9), and the Fatigue Severity Scale (FSS). Data from 52 subjects, who completed both assessments, were analyzed using a regression-based serial multiple mediation model (PROCESS Model 6). RESULTS: Bootstrap analyses indicated no direct effects of T1 FSS on T2 IES-R but significant positive indirect effects of T1 FSS on T2 IESR through T1 PHQ-9 and T2 PHQ-9 (B=2.1601, SE=1.3268, 95% confidence interval=0.4250–6.1307). In other words, both T1 PHQ-9 and T2 PHQ-9 fully mediated the relationship between T1 FSS and T2 IES. CONCLUSION: Chronic fatigue 12 months after MERS had indirect effects on prolonged PTSSs 18 months after MERS via persisting depression in MERS survivors. This finding supports the need to promote interventional programs for emerging infectious disease survivors with chronic fatigue to reduce depression and prevent prolonged PTSSs.

ABSTRACT

OBJECTIVES: Patients with an infectious diseases during an outbreak can experience extreme fear and traumatic events in addition to suffering from their medical illness. This study examined the long-term impact of the outbreak of Middle East Respiratory Syndrome (MERS) in Korea, 2015 on the mental health of the survivors. METHODS: Sixty-three survivors from MERS were recruited from a prospective cohort study at six hospitals one year after the outbreak in 2015. The Korean-Symptom Check List 95 was administered to evaluate their psychiatric problems and analyzed according to the patient's characteristics and exposure to traumatic events during the outbreak. RESULTS: A total of 63.5% of survivors suffered from significant psychiatric problems: post-traumatic symptoms (36.5%), sleep problems (36.5%), anxiety (34.9%), and depression (30.2%). Survivors with a history of a ventilator treatment during the MERS epidemic, a family member who died from MERS, and a past psychiatric history showed higher post traumatic stress disorder, anxiety, depression, and suicidality than people who do not have those histories. CONCLUSION: The study suggests that MERS survivors could have a high chance of adverse psychiatric consequences, even after their recovery from MERS. Exposure to traumatic events during the outbreak and premorbid individual vulnerability would affect the long-term mental health problems.

ABSTRACT

OBJECTIVE: Declines in naming ability and semantic memory are well-known features of early Alzheimer's disease (AD). We developed a new screening algorithm for AD using two brief language tests : the Categorical Fluency Test (CFT) and 15-item Boston Naming Test (BNT15). METHODS: We administered the CFT, BNT15, and Mini-Mental State Examination (MMSE) to 150 AD patients with a Clinical Dementia Rating of 0.5 or 1 and to their age- and gender-matched cognitively normal controls. We developed a composite score for screening AD (LANGuage Composite score, LANG-C) that comprised demographic characteristics, BNT15 subindices, and CFT subindices. We compared the diagnostic accuracies of the LANG-C and MMSE using receiver operating curve analysis. RESULTS: The LANG-C was calculated using the logit of test scores weighted by their coefficients from forward stepwise logistic regression models : logit (case)=12.608−0.107×age+1.111×gender+0.089×education−0.314×HS(1st)−0.362×HS(2nd)+0.455×perseveration+1.329×HFCR(2nd)−0.489×MFCR(1st)−0.565×LFCR(3rd). The area under the curve of the LANG-C for diagnosing AD was good (0.894, 95% confidence interval=0.853–0.926 ; sensitivity=0.787, specificity=0.840), although it was smaller than that of the MMSE. CONCLUSION: The LANG-C, which is easy to automate using PC or smart devices and to deliver widely via internet, can be a good alternative for screening AD to MMSE.

ABSTRACT

OBJECTIVE: We investigated the impact of depressed mood (dysphoria) and loss of interest or pleasure (anhedonia)on the risk of dementia in cognitively-normal elderly individuals. METHODS: This study included 2,685 cognitively-normal elderly individuals who completed the baseline and 4-year follow-up assessments of the Korean Longitudinal Study on Cognitive Aging and Dementia. We ascertained the presence of dysphoria and anhedonia using the Mini International Neuropsychiatric Inventory. We defined subjective cognitive decline as the presence of subjective cognitive complaints without objective cognitive impairments. We analyzed the association of dysphoria and anhedonia with the risk of cognitive disorders using multinomial logistic regression analysis adjusted for age, sex, education, Cumulative Illness Rating Scale score, Apolipoprotein E genotype, and neuropsychological test performance. RESULTS: During the 4-year follow-up period, anhedonia was associated with an approximately twofold higher risk of mild cognitive impairment (OR=2.09, 95% CI=1.20–3.64, p=0.008) and fivefold higher risk of dementia (OR=5.07, 95% CI=1.44–17.92, p=0.012) but was not associated with the risk of subjective cognitive decline. In contrast, dysphoria was associated with an approximately twofold higher risk of subjective cognitive decline (OR=2.06, 95% CI=1.33–3.19, p=0.001) and 1.7-fold higher risk of mild cognitive impairment (OR=1.75, 95% CI=1.00–3.05, p=0.048) but was not associated with the risk of dementia. CONCLUSION: Anhedonia, but not dysphoria, is a risk factor of dementia in cognitively-normal elderly individuals.

ABSTRACT

OBJECTIVE: This study aimed to examine the association between normal-but-low folate levels and cognitive function in the elderly population using a prospective cohort study. METHODS: We analyzed 3,910 participants whose serum folate levels were within the normal reference range (1.5–16.9 ng/mL) at baseline evaluation in the population-based prospective cohort study named the “Korean Longitudinal Study on Cognitive Aging and Dementia.” The association between baseline folate quartile categories and baseline cognitive disorders [mild cognitive impairment (MCI) or dementia] was examined using binary logistic regression analysis adjusting for confounding variables. The risks of incident MCI and dementia associated with the decline of serum folate level during a 4-year follow-up period were examined using multinomial logistic regression analysis. RESULTS: The lowest quartile group of serum folate (≥1.5, ≤5.9 ng/mL) showed a higher risk of cognitive disorders than did the highest quartile group at baseline evaluation (odds ratio 1.314, p=0.012). Over the 4 years of follow-up, the risk of incident dementia was 2.364 times higher among subjects whose serum folate levels declined from the 2nd–4th quartile group to the 1st quartile than among those for whom it did not (p=0.031). CONCLUSION: Normal-but-low serum folate levels were associated with the risk of cognitive disorders in the elderly population, and a decline to normal-but-low serum folate levels was associated with incident dementia. Maintaining serum folate concentration above 5.9 ng/mL may be beneficial for cognitive status.

ABSTRACT

OBJECTIVES: This study was conducted to evaluate the gender differences in stress-coping methods that affect stress responses in graduate medical students.METHODS: The participants were 209 students of C medical school in Daejeon, Korea. Stress response was measured using the Stress Response Inventory. Coping methods were measured through the Ways of Coping Checklist and Problem-solving Style Scale. Data were analyzed using T-Tests, a correlation analysis, and stepwise multiple regression analysis.RESULTS: The mean±standard deviation score of the stress response inventory was 23.56±20.20 in males and 32.34±23.44 in females. The stepwise multiple regression analysis revealed the following factors related to stress response: helplessness, problem-solving control, approach style in males and helplessness, social readjustment rating scale, problem-solving confidence in females. No relationship between stress-coping style and academic performance was found in both genders.CONCLUSION: Hopelessness seemed to be the main reason for the stress response in medical students of both genders. We also found differences in coping methods affecting the stress response by genders. Future studies need to identify more such factors that lead to differences in coping methods and help adapt to stress in medical education.

ABSTRACT

OBJECTIVE: This study evaluated the outcomes of ischemic stroke patients according to delirium motor subtype.METHODS: This study included patients who were admitted to the stroke unit between August 2017 and March 2019 and met the DSM-5 diagnostic criteria for delirium. Patients were assessed twice weekly throughout their delirium episodes using the Korean version of the Delirium Motor Subtype Scale (K-DMSS) and the Korean version of the Delirium Rating Scale-Revised-98 (K-DRS-98). The clinical characteristics and short-term outcomes of the patients were also assessed.RESULTS: A total of 943 stroke patients were included; the rate of incident delirium was 10.18%. Of the 95 delirium patients, 34 were classified as the hyperactive subtype, 30 as the mixed subtype, 25 as the hypoactive and six as no subtype. Among the subtype groups, the hypoactive subtype had the highest initial scores on the National Institutes of Health Stroke Scale (NIHSS; 6.72±4.75, p=0.02) and the modified Rankin Scale (mRS; 3.96±1.24, p<0.01). Additionally, the mixed and hypoactive subtypes had longer durations (p<0.01) and more severe symptoms of delirium (p=0.03) than the other motor subtypes, and the hypoactive subtype group had a significantly longer hospital stay (36.88±27.71 days, p<0.01) than the other subtype groups. After adjusting for baseline covariates in a multiple linear regression analysis, these differences remained significant.CONCLUSION: The present results suggest that the motor subtype of delirium is associated with different characteristics and outcomes in ischemic stroke patients.

ABSTRACT

OBJECTIVE: The Delirium Motor Subtype Scale (DMSS) is a validated and reliable instrument developed from various methods previously used to assess delirium motor subtypes. It focuses on pure motor disturbances with a relative specificity for delirium. The aim of this study was to investigate the validity and reliability of a Korean version of the DMSS (K-DMSS). METHODS: We recruited 145 patients who were older than 60 years and had been referred for psychiatric consultation for delirium. These patients were evaluated using the K-DMSS, Liptzin & Levkoff criteria, and the Korean version of the Delirium Rating Scale-Revised-98 (K-DRS-R98) to compare delirium motor subtypes. RESULTS: The internal consistency of the K-DMSS in assessing delirium motor subtypes was acceptable (Cronbach's alpha=0.79). Delirium motor subtypes identified with the K-DMSS and K-DRS-R98 showed almost perfect agreement (Cohen's Kappa=0.81), while those identified with the K-DMSS and Liptzin & Levkoff criteria showed substantial agreement (Cohen's Kappa=0.78). CONCLUSION: Our results suggest that the K-DMSS is a valid and reliable tool for identifying delirium subtypes.

ABSTRACT

OBJECTIVE: We investigated the prevalence and risk factors of physically abusive behaviors (PhAB) and psychologically abusive behaviors (PsAB) towards people with dementia (PWD) in family caregivers, and compared their prevalences between East Asian and Western countries. METHODS: We estimated the prevalence and risk factors of PhAB and PsAB in 467 Korean pairs of community-dwelling PWD and their primary family caregivers. We evaluated abusive behaviors using the Modified Conflict Tactics Scale. In addition, we compared the prevalence of abusive behaviors between Asian and Western countries through a meta-analysis on 12 studies including the current one. RESULTS: More than a half of the caregivers reported PsAB and about one out of seven caregivers admitted PhAB within past three months. PsAB and PhAB were slightly more prevalent in East Asian countries than in Western countries. Non-Alzheimer type and moderate to severe behavioral and psychological symptoms of dementia were associated with the risk of PhAB but not with the risk of PsAB. Severe care burden and low income were associated with the risk of PhAB and PsAB. CONCLUSION: PhAB and PsAB were as prevalent in the family caregivers of PWD in Asian countries including Korea as in Western countries. Prevention strategies should be implemented according to the type of abusive behaviors.

ABSTRACT

OBJECTIVE: This study aimed to identify the core symptoms of delirium, particularly in elderly people associated with major risk factors, using the Korean version of the Delirium Rating Scale-Revised-98. METHODS: The study sample consisted of 200 patients (mean age: 72.7±3.9 years, male: 68.5%) who had been diagnosed with delirium. Exploratory factor analysis was used to investigate the factor structure, and confirmatory factor analysis was used to evaluate the goodness of fit of the results. RESULTS: The results demonstrated three core domains of delirium in the elderly patients: 1) the cognitive domain (e.g., language, thought process, orientation, attention, long-term memory, and visuospatial ability); 2) the circadian domain (e.g., sleep-wake cycle and motor behavior); and 3) the short-term memory domain (short-term memory). These results were confirmed by confirmatory factor analysis. CONCLUSION: The findings of this study suggest a theoretical domain structure for delirium in elderly patients.
