The Influence of the Burden of Nurturing and Depression on Sleep Quality in Female Full-Time Homemakers : The Moderated Mediating Effect of Monthly Income / 수면정신생리

Objectives@#This study investigated sleep quality in female full-time homemakers and evaluated the relationship of sleep disturbance with psychological and socio-environmental factors. @*Methods@#This cross-sectional study adopted a structured survey and sequential recruitment method for randomized participation of community-dwelling full-time female homemakers. Sleep quality and mental health were measured using the Korean version of the Pittsburgh Sleep Quality Index (K-PSQI), Korean version of the Beck Depression Inventory-II (K-BDI-II), Korean version of the Beck Anxiety Inventory (K-BAI), and Korean version of the Beck Hopelessness Scale (K-BHS). The willingness-to-pay (WTP) method was selected to measure the self-evaluated monetary value of household service work. The relationship among the main relevant factors was statistically analyzed through a mediation model. @*Results@#A total of 166 participants were analyzed and classified having poor versus good sleep quality (poor : 24.1%, n = 40 ; good : 75.9%, n = 126 ; cut-off point = 9 on the K-PSQI). Significant between-group differences were observed in mental health status (K-BDI-II, p < 0.001 ; K-BAI, p < 0.001 ; K-BHS, p = 0.003). The moderated mediation model was verified, indicating that depression may mediate the association between nurturing burden and sleep disturbance. The path from nurturing burden to depression may be moderated by average monthly household income. @*Conclusion@#A relatively high portion of full-time female homemakers may suffer from sleep disturbance and interactions between psychological and socio-environmental factors might determine sleep quality, suggesting the need for public health policies targeting improvement of sleep quality and mental health among full-time homemakers.

Depression and Gap between Perceived- and Self-Willingness-to-Pay for Labor in Community-Dwelling Full-Time Female Homemakers / 신경정신의학

OBJECTIVES@#Knowledge of labor and mental health status of full-time homemakers is essential for the health and maintenance of our society. This study investigated the current states of mental health and related factors in full-time female homemakers, and the effect of the gap between socially evaluated (perceived)- and self-evaluated value of labor of full-time female homemakers on depression.@*METHODS@#Participants were sequentially recruited from among community-dwelling full-time female homemakers, and assessed using structured questionnaires composed of general items as well as Korean versions of Beck Depression Inventory-II (K-BDI-II), Beck Anxiety Inventory (K-BAI), and Beck Hopelessness Scale (K-BHS). The willingness-to-pay (WTP) approach was used to measure perceived and self-evaluated values of labor of full-time homemakers.@*RESULTS@#A total of 169 participants were enrolled. The analytical results showed that 45.2% of participants were positive when screened by BDI (mild to severe depression), 39.6% positive by K-BAI (anxiety), and 60.9% positive by K-BHS (hopelessness). Multiple regression analysis of significant factors related to depression were burden of nurturing (t=3.99, p<0.001), monthly income (t=−3.24, p<0.01), and relationship with husband (t=−3.03, p<0.01). Logistic regression analysis showed that the gap between perceived- and self-WTP was a significant negative impact factor for depression level transition (K-BDI-II≥14) (p=0.025, odds ratio=0.995).@*CONCLUSION@#The results showed that full-time female homemakers are under relatively risky conditions and are associated with blind spots in the mental health perspective, suggesting that social support and a political approach are necessary for the maintenance of mental health of full-time female homemakers.

Efficacy of Galantamine on Cognition in Mild-to-Moderate Alzheimer's Dementia after Failure to Respond to Donepezil

OBJECTIVE: This study compares the efficacy of the cholinesterase inhibitor (ChEI) galantamine on cognition in patients with mild-to-moderate Alzheimer's dementia (AD) who were either naïve to ChEI drugs or who had failed a trial of the ChEI donepezil. METHODS: Outpatients with AD were sequentially referred for screening and enrollment. Current outpatients who had taken donepezil for at least 6 months without demonstrated efficacy on cognition were switched to galantamine (switched group). New outpatients with no ChEI prescription history were classified as the naïve group and were given galantamine. The primary outcome measures for the between-group comparison were response rate on cognition at 26 and 52 weeks (categorical) and change on the Korean version of the Alzheimer's Disease Assessment Scale-cognitive subscale (dimensional). Secondary cognitive outcomes were measured using the subset of frontal executive function and the Korean Mini-Mental State Examination. RESULTS: Seventy outpatients were enrolled and 66 were analyzed by Intent-to-treat (ITT). There were 42 cases in the naïve group and 24 in the switched group. Response rates did not differ at 26 weeks (71.4% naïve vs. 58.3% switched; p=0.277) or at 52 weeks (59.5% naïve vs. 41.6% switched; p=0.162). No significant differences were observed in the pattern of change over the 52 weeks on the primary and secondary cognitive scales. CONCLUSION: As the efficacy of galantamine on cognition was not inferior in the switched group compared to that in the naïve group, switching ChEI drugs is clinically feasible for non-responding patients with mild-to-moderate AD.

A Provincial Population-Based Survey on Attitudes towards Wills of Individuals with Dementia and Related Issues / 신경정신의학

OBJECTIVES: This study investigated the attitudes of a provincial population towards wills of individuals with dementia and related concerns to prevent civil disputes related to dementia in an aging society. METHODS: The target population was registered residents in a province aged 19 years or older. The population forming the sampling frame was 1478821 (as of May 31, 2013). With a confidence interval of 2% and significance level of 5%, 2540 participants were sampled. This survey used a structured questionnaire composed of two main parts : seven items of general information (sex, age, residence, marital status, education, occupation, and income) and Testamentary Capacity-Related Questionnaire-12 items (TCRQ-12) comprising four items of basic knowledge and eight items of specific situational questions, using a five point Likert scale. RESULTS: The respondents were favorable toward the guarantee of will-making capacity of individuals with dementia. Self-relatedness, disadvantageousness and undue influence are significantly associated with objection to the will of individuals with dementia. In the pre-evaluation of testamentary capacity of individuals with dementia, the respondents responded strongly and with more favorable attitudes for evaluation by medical specialists than by lawyers. Last, in acceptance of the denial of self-related will due to dementia, negative response was dominant over positive response. CONCLUSION: Although it would be desirable that the will or testamentary capacity of individuals with dementia should be guaranteed for maximum, institutional and professional approaches are necessary to prevent civil disputes related to dementia.

Atypical Antipsychotics for Behavioral and Psychological Symptoms in Alzheimer's Dementia

In addition to cognitive and functional decline, various behavioral and psychological symptoms in dementia (BPSD) are manifested in the patients with Alzheimer's dementia (AD). Some of BPSD, especially psychosis, agitation, and aggression could be challenges to caregivers and clinicians. Atypical antipsychotic drugs (risperidone, olanzapine, quetiapine, and aripiprazole) are widely prescribed to manage complicated neuropsychiatric symptoms associated with AD. It is known that atypical antipsychotics (AAP) have modest and significant beneficial effects in the short term treatment of BPSD. However their safety of AAP has been concerned with potentially increased adverse events. This article reviewed the treatment outcomes and adverse effects of AAP when managing BPSD in the patients with AD. The effects of risperidone and aripiprazole are obvious on psychosis and aggression, but with small effect size. AAP could exacerbate cognitive decline, and it could increase the rate of cerebrovascular accidents and mortality rate in the patients with AD.

Bilateral Repetitive Transcranial Magnetic Stimulation for Auditory Hallucinations in Patients with Schizophrenia: A Randomized Controlled, Cross-over Study

OBJECTIVE: A randomized double-blind cross-over trial was conducted in patients with persistent auditory hallucinations (AHs) to investigate whether bilateral repetitive transcranial magnetic stimulation (rTMS) at the temporoparietal area or Broca's area is more effective at high- or low-frequencies compared to a sham condition. METHODS: Twenty three patients with persistent AHs who remained stable on the same medication for 2 months were enrolled. They were randomized to one of four conditions: low-frequency (1 Hz)-rTMS to the temporoparietal area (L-TP), high-frequency (20 Hz)-rTMS to the temporoparietal area (H-TP), high-frequency (20 Hz)-rTMS to Broca's area (H-B), or sham. RESULTS: All the four rTMS conditions resulted in significant decrease in the scores under the auditory hallucination rating scale and hallucination change scale over time. However, there were no significant treatment effects or interaction between time and treatment, suggesting no superior effects of the new paradigms over the sham condition. CONCLUSION: Our findings suggest that bilateral rTMS at the temporoparietal area or Broca's area with high- or low-frequency does not produce superior effects in reducing AHs compared to sham stimulation.

Effects of Galantamine Treatment on Attention, Activities of Daily Living, and Neuropsychiatric Symptoms between the Patients with Pure Alzheimer's Disease and Mixed Dementia

OBJECTIVES: The purpose of this study was to compare the efficacy of galantamine treatment, especially attention ability between patients with pure Alzheimer's disease (AD) and Mixed dementia (MD) during a 24-week trial. METHODS: A total of 40 patients were recruited for this 24-week study. The effect of galantamine on attention was measured using Seoul Computerized NeuroCognitive Function Test (SCNT) and frontal functions test of Seoul Neuropsychological Screening Battery (SNSB). Patients'activities of daily living using the Seoul-Activities of Daily Living (S-ADL) and the Seoul-Instrumental Activities of Daily Living (S-IADL) ; behavioral symptoms using the Korean version Neuropsychiatric Inventory (K-NPI) were measured at baseline and 24-week. RESULTS: 17 pure AD patients and 23 MD patients were analyzed in this study. Attention as measured by SCNT was not significantly different from baseline after 24 weeks of treatment in both groups. There was no significant difference between two groups in mean change from baseline in the SCNT, S-ADL, S-IADL and K-NPI scores at 24-week. CONCLUSION: Galantamine showed a therapeutic effect on cognition, activities of daily living, neuropsychiatric symptoms in pure AD and MD. Furthermore, Galantamine may specifically help to maintain attention and it may have positive effects on other cognitive and functional abilities.

Comparative Assessment of Clinical Efficacy between the Naive and the Switching Group to Donepezil: 12 Months Prospective Study

OBJECTIVES: The purpose of this study was to compare the efficacy between switching patients with Alzheimer's disease (AD) from galantamine or rivastigmine to donepezil because they were not responding adequately, and naive patients with AD who initiated therapy with donepezil. METHODS: A total of 108 patients were recruited for this 52-week study. The effect of donepezil on cognitive function was measured using Alzheimer's Disease Assessment Scale-cognitive subscale-preliminary Korean version (ADAS-cog-K). Patients' activities of daily living using Seoul-Activities of Daily Living (S-ADL) and the Seoul-Instrumental Activities of Daily Living (S-IADL);behavioral symptoms using the Korean version Neuropsychiatric Inventory (K-NPI) were measured at baseline, 13-weeks, 26-weeks, 39-weeks and 52-weeks. We defined the responsive patients to donepezil at those who showed a cognitive improvement or no change during the first six-month clinical trial. RESULTS: 86 naive patients and 22 switching patients were enrolled in the study. 74 patients completed the study and 34 discontinued their treatment before week 52. There was no significant difference between two patient groups in demographic data, baseline characteristics and dementia severity except duration of illness. The total ADAS-cog-K scores were not significantly different from baseline after 52 weeks of treatment in both groups. Both groups demonstrated deterioration of S-ADL and S-IADL at 52 weeks. The NPI scores did not significantly change in both groups. Based on the operational criteria, 61.6% of the naive group and 54.5% of the switching group were responders to donepezil. CONCLUSION: The switching group had similar levels of efficacy with the naive group who initiated therapy with donepezil. These results suggest that patients not responding adequately to rivastigmine or galantamine may improve or stabilize after switching to donepezil and prior medication does not effect donepezil's efficacy.

Comparative Assessment of Clinical Efficacy after 12-Month Clinical Trial of Donepezil between the Patients with Pure Alzheimer's Disease and Mixed Dementia

OBJECTIVES: The purpose of this study was to compare the efficacy of donepezil treatment between patients with pure Alzheimer's disease (AD) and Mixed dementia (MD) during a 12-month trial. METHODS: A total of 139 patients were recruited for this 52-week study. The effect of donepezil on cognitive function was measured using Alzheimer's Disease Assessment Scale-cognitive subscale-preliminary Korean version (ADAS-cog-K). Patients' activities of daily living using the Seoul-Instrumental Activities of Daily Living (S-IADL) and Seoul-Activities of Daily Living (S-ADL);behavioral symptoms using the Korean version Neuropsychiatric Inventory (K-NPI) were measured at baseline, 13-weeks, 26-weeks, 39-weeks and 52-weeks. We defined the responsive patients to donepezil at those who showed a cognitive improvement or no change during the first six-month clinical trial. RESULTS: 84 pure AD patients and 34 MD patients were available for intent-to-treat (ITT) last observation carried forward (LOCF) analysis. There was no significant difference between two groups in mean change from baseline in the total ADAS-cog-k, S-ADL, S-IADL and K-NPI scores at 52-week. Based on the operational criteria, 60.7% of pure AD patients and 58.8% of MD patients were responders to donepezil. CONCLUSION: MD patients had similar levels of efficacy with pure AD patients and donepezil was well tolerated in both groups. These results suggest that donepezil is an effective and well-tolerated treatment for MD patients as well as for pure AD patients.

CONCLUSION: MD patients had similar levels of efficacy with pure AD patients and donepezil was well tolerated in both groups. These results suggest that donepezil is an effective and well-tolerated treatment for MD patients as well as for pure AD patients.

Clinical Efficacy and Safety of Memantine in Patients with Moderate to Severe Dementia / 대한정신약물학회지

OBJECTIVE: This study examined the efficacy and safety of memantine-an uncompetitive N-methyl-D-aspartate (NMDA) receptor antagonist-in the treatment of moderate-to-severe dementia. METHODS: Forty-four patients with moderate-to-severe dementia received 20 mg of memantine daily for 24 weeks. The primary efficacy variable was measured by the Korean version of Severe Impairment Battery(K-SIB), and the secondary efficacy variables were measured using the Seoul-Activites of Daily Living(S-ADL) and Neuropsychiatric Inventory-Questionnaire(NPI-Q). Neuropsychological assessments were administrated at baseline, 12 weeks, and 24 weeks. Safety parameters were monitored. RESULTS: Of 44 patients recruited, 30 completed the study and 14 dropped out. Memantine-treated patients showed a therapeutic benefit in all efficacy variables ; the K-SIB, S-ADL, and NPI-Q total scores were not significantly different from baseline either at the endpoint(in the analysis of intention-to-treat, with the last observation carried forward, ITT-LOCF) or at week 24(in the analysis of observed cases, OC). The response rates, when "response" was defined as improved or unchanged in the K-SIB or the S-ADL scores, were 43.3 and 50%, respectively(in the analysis of OC). The responders showed significant improvement in the cognitive subdomain of memory function, praxis, visuospatial ability, and orienting to name. Memantine was shown to be tolerable and safe. CONCLUSIONS: Memantine treatment reduced or delayed clinical deterioration in cognition, function, and behavior in patients with moderate-to-severe dementia.

Comparison of bone mineral density in premature ovarian failure patients and spontaneous menopausal women / 대한산부인과학회잡지

OBJECTIVE: It is widely accepted that the estrogen plays an important role in the maintenance of bone mineral density (BMD). The purpose of this study is to compare the BMD between premature ovarian failure (POF) patients and spontaneous menopausal women, both of which are characterized by estrogen deficiency. METHOD: We compared the BMD of Lumbar 2-4 and Femur neck(right) measured by dual energy X-ray absorptiometry in 17 premature ovarian failure patients and 21 spontaneous menopausal women. RESULTS: POF patients and spontaneous menopausal women showed the BMD of 1.000+/-0.165g/cm2, 1.167+/-0.279g/cm2 at Lumbar 2-4 and 0.793+/-0.132g/cm2, 0.885+/-0.128g/cm2 at Femur neck, respectively. POF patients had lower BMD of Lumbar 2-4 and Femur neck significantly(p<0.05). FSH and estradiol level were not different between the two groups. CONCLUSION: This study demonstrated that the BMD in POF patients was decreased more severely than that of spontaneous menopausal women. Therefore, more preventive measures against bone loss is required in POF patients than spontaneous menopausal women.
