Abstract
OBJECTIVE It was unclear whether older people without dementia who attempted suicide were at increased risk of subsequently developing dementia. METHODS Using the Taiwan National Health Insurance Research Database, 1,189 patients aged ≥ 65 years who attempted suicide and 4,756 age- and sex-matched control subjects were enrolled in our study and followed to the end of 2011. Those who developed dementia during the follow-up were identified. RESULTS Cox regression analysis, after adjusting for demographic data and medical comorbidities, found that geriatric suicide attempt was associated with an increased risk of subsequent dementia (HR: 7.40; 95% CI: 6.11-8.97; Wald χ2 = 414.87, df = 1, p < 0.001). Both patients aged between 65 and 79 years (HR: 7.74; 95% CI: 6.17-9.71; Wald χ2 = 312.62, df = 1, p < 0.001) and patients aged ≥ 80 years (HR: 6.94; 95% CI: 4.73-10.17; Wald χ2 = 97.78, df = 1, p < 0.001) who attempted suicide had an increased risk of developing dementia in later life. CONCLUSION The elderly who attempted suicide were prone to developing dementia in later life, independent of depression and medical comorbidities. Further studies are necessary to clarify the underlying mechanisms between geriatric suicide and dementia and whether the prompt intervention for geriatric suicide may reduce this risk.

Abstract
OBJECTIVES Previous studies suggested a relationship between posttraumatic stress disorder (PTSD) in the specific population (i.e., war survivors and veterans) and subsequent dementia risk. However, whether patients with PTSD in the general population were at an increased risk for developing dementia in later life remained unclear. METHODS The Cox regression analysis was performed using data from the Taiwan National Health Insurance Research Database. The study sample comprised 1750 patients diagnosed with PTSD between 2001 and 2009 and 7000 age-/sex-matched individuals without PTSD. Those who developed dementia during follow-up to the end of 2011 were identified. RESULTS After adjusting for demographic data and medical and psychiatric comorbidities, PTSD was an independent risk factor for the risk for subsequent dementia (hazard ratio [HR]=4.37; 95% confidence interval [CI]: 2.53-7.55). There was a dose-dependent relationship between PTSD severity indicated by the frequency of psychiatric clinics visiting of PTSD (times per year) and the risk of subsequent dementia (<5: HR: 2.81, 95% CI: 1.50-5.29; 5-10: 6.90, 95% CI: 3.09-15.40;>10: HR: 18.13, 95% CI: 9.13-36.00). Furthermore, patients with depressive disorder and medical comorbidities, such as cerebrovascular diseases, diabetes mellitus, and head injuries, exhibited a higher risk for developing dementia. DISCUSSIONS Our study suggested a significant dose-dependent association between PTSD and its severity and an increased risk of developing dementia later in life. The importance of mental care for trauma victims would increase in the coming century, and our findings broadened another era for the end result of a widely prevalent psychiatric disorder.

Abstract
In a maca-containing herbal supplement claimed to remedy erectile dysfunction, a new sildenafil analogue was found using adulterant screening with TLC, GC-MS and LC-MS/MS. This compound was isolated by column chromatography and HPLC, and identified by extensive 1D- and 2D-NMR and mass spectral analyses. The structure of this new compound was established as 5-[2-ethoxy-5-(piperazine-1-carbonyl) phenyl]-1-methyl-3-propyl-1,6-dihydro-pyrazolo[4,3-d]pyrimidin-7-one, and was named desethylcarbodenafil.

Abstract
OBJECTIVE Studies have suggested the association between autism spectrum disorder (ASD) and type 2 diabetes mellitus (DM)-related risk factors, such as obesity and dyslipidemia. However, the association between ASD and type 2 DM remains unknown. RESEARCH DESIGN AND METHODS We used the Taiwan National Health Insurance Research Database for enrolling 6,122 adolescents and young adults with ASD and 24,488 age- and sex-matched control subjects between 2002 and 2009 and monitored them until the end of 2011. Participants who developed type 2 DM during the follow-up period were identified. RESULTS Adolescents (hazard ratio [HR] 2.71 [95% CI 1.64-4.48]) and young adults (HR 5.31 [95% CI 2.85-9.90]) with ASD had a higher risk of developing type 2 DM than those without ASD, after adjustment for demographic data, atypical antipsychotics use, and medical comorbidities. Sensitivity analyses after excluding first year (HR 3.03 [95% CI 2.03-4.51]) and first 3-year (HR 2.62 [95% CI 1.62-4.23]) observation periods were consistent. Short-term (HR 1.97 [95% CI 1.20-3.23]) and long-term (HR 1.64 [95% CI 1.02-2.63]) use of atypical antipsychotics were associated with a higher likelihood of subsequent type 2 DM. CONCLUSIONS Adolescents and young adults with ASD were more likely to develop type 2 DM during the follow-up. In addition, those with ASD using atypical antipsychotics exhibited a high risk. Therefore, further research is necessary to investigate the common pathophysiology of ASD and type 2 DM.

Abstract
OBJECTIVES Bipolar I disorder (BD) is a highly heritable disorder characterized by mood swings between high-energy and low-energy states. Amygdala hyperactivity and cortical inhibitory hypoactivity [e.g., of the dorsolateral prefrontal cortex (dlPFC)] have been found in patients with BD, as evidenced by their abnormal resting-state functional connectivity (FC) and glucose utilization (GU). However, it has not been determined whether functional abnormalities of the dlPFC-amygdala circuit exist in unaffected, healthy siblings of the patients with BD (BDsib). METHODS Twenty euthymic patients with BD, 20 unaffected matching BDsib of the patient group, and 20 well-matched healthy control subjects were recruited. We investigated seed-based FC (seeds: dlPFC) with resting-state functional magnetic resonance imaging and GU in the regions of interest (e.g., dlPFC and amygdala) using (18) F-fluorodeoxyglucose positron emission tomography. RESULTS The FC in the dlPFC (right)-amygdala circuit was statistically abnormal in patients with BD and BDsib, but only the patients with BD demonstrated hypoactive GU bilaterally in the dlPFC and hyperactive GU bilaterally in the amygdala. Facilitating differentiation between the BD groups, the altered FC between dlPFC (right) and amygdala (left) was even more prominent in the patients with BD (p < 0.05). CONCLUSIONS There was a dysfunctional connection with intact GU in the dlPFC-amygdala circuit of the BDsib, which highlights the vulnerability in families with BD. Diminished top-down control from the bilateral dlPFC, which prevents adequate inhibition of limbic hyperactivity, might mediate the development of BD.

Abstract
A high-performance liquid chromatography (HPLC) method was developed for the determination of maleic acid which was released from starch maleate (SM) through the alkaline hydrolysis reaction. The proper alkaline hydrolysis conditions and LC separation are reported in this study. The starch samples were treated with 50% methanol for 30 minutes, and then hydrolyzed by 0.5N KOH for 2 hours to release maleic acid. A C18 column and gradient mobile phase consisting of 0.1% phosphoric acid and methanol at a flow rate of 1.0 mL/minute were used for separation. The method showed a good linearity in the range of 0.01–1.0 ìg/mL, with a limit of quantification (LOQ) at 10 mg/kg in starch. The recoveries in corn starch, noodle, and fish balls were between 93.9% and 108.4%. The relative standard deviation (RSD) of precision was <4.9% (n = 3). This valid method was rapid, sensitive, precise, and suitable for routine monitoring of the illegal adulteration of SM in foods.

Abstract
Bipolar disorder (BD) is a major psychiatric disorder that is easily misdiagnosed. Patient adherence to a treatment regimen is of utmost importance for successful outcomes in BD. Several trials of antipsychotics suggested that depot antipsychotics, including long-acting first- and second-generation agents, are effective in preventing non-adherence, partial adherence, and in reducing relapse in BD. Various long-acting injectable (LAI) antipsychotics are available, including fluphenazine decanoate, haloperidol decanoate, olanzapine pamoate, risperidone microspheres, paliperidone palmitate, and aripiprazole monohydrate. Due to the increasing number of BD patients receiving LAI antipsychotics, treatment guidelines have been developed. However, the clinical applicability of LAI antipsychotics remains a global cause for concern, particularly in Asian countries. Expert physicians from Taiwan participated in a consensus meeting, which was held to review key areas based on both current literature and clinical practice. The purpose of this meeting was to generate a practical and implementable set of recommendations for LAI antipsychotic use to treat BD; target patient groups, dosage, administration, and adverse effects were considered. Experts recommended using LAI antipsychotics in patients with schizophrenia, rapid cycling BD, BD I, and bipolar-type schizoaffective disorder. LAI antipsychotic use was recommended in BD patients with the following characteristics: multiple episodes and low adherence; seldom yet serious episodes; low adherence potential per a physician’s clinical judgment; preference for injectable agents over oral agents; and multiple oral agent users still experiencing residual symptoms.

Abstract
Background Family caregivers may not agree with patients with dementia regarding attitudes toward end-of-life preferences, and the effects of this type of disagreement are not well understood. This study sought to identify such a disagreement and its predictors. Methods A cross-sectional sample of 84 family caregivers and patients with dementia was recruited from memory clinics. We used the Mini-Mental State Examination, Neuropsychiatric Inventory, Clinical Dementia Rating, and Katz index of independence in activities of daily living to assess patient symptoms, functions, and severity of dementia. Caregivers completed questionnaires on perceived patient end-of-life care preferences, caregiver end-of-life care preferences for patients, Zarit Burden Interview (ZBI), Center for Epidemiological Studies–Depression Scale (CES-D), and knowledge of clinical complications of advanced dementia. Results The self-disclosure rates of patient preferences were 34.5% for tube feeding, 39.3% for cardiopulmonary resuscitation, and 45.2% for mechanical ventilation. For patients who had disclosed preferences, the disagreement rate between them and their caregivers was 48.3% for tube feeding, 48.5% for cardiopulmonary resuscitation, and 60.3% for mechanical ventilation. Caregiver depression (i.e., CES-D ≥16) was associated with disagreements on cardiopulmonary resuscitation (adjusted odds ratio (aOR) = 6.6, 95% CI = 1.4–31.1, P = 0.01) and mechanical ventilation (aOR = 14, 95% CI = 2.2–87.2, P = 0.005) preferences. Conclusion The preferences of end-of-life issues differed greatly between dementia patients and their caregivers. Depression in caregivers is associated with such discrepancy.

Abstract
BACKGROUND & AIMS It remains unknown what the prevalence of minimal hepatic encephalopathy is in Taiwan, a highly endemic country for chronic viral hepatitis infection. It is also unclear whether abnormal serum cytokine levels can be indicative of the presence of minimal hepatic encephalopathy. We aimed to standardize the tests of psychometric hepatic encephalopathy score and predictive value of proinflammatory cytokines in minimal hepatic encephalopathy in Taiwan. METHODS 180 healthy subjects and 94 cirrhotic patients without a history of overt hepatic encephalopathy from a tertiary center were invited to participate in this cross-sectional study. Blood sampling for determination of serum levels of interleukin 6 and 18 and tumor necrosis factor-α was performed. Based on the normogram of psychometric hepatic encephalopathy score from healthy volunteers, patients with minimal hepatic encephalopathy were identified from the cirrhotic patients using the criterion of a psychometric hepatic encephalopathy score less than -4. RESULTS In the healthy subjects, age and education were predictors of subtests of psychometric hepatic encephalopathy score. Minimal hepatic encephalopathy was identified in 27 (29%) cirrhotic patients. Serum interleukin 6 level (OR = 6.50, 95% CI = 1.64-25.76, P = 0.008) was predictive of the presence of minimal hepatic encephalopathy after multivariate analysis. CONCLUSIONS The psychometric hepatic encephalopathy score can be a useful tool for detecting patients with minimal hepatic encephalopathy in Taiwan and around one third of cirrhotic outpatients fulfill this diagnosis. A high serum interleukin 6 level is predictive of the presence of minimal hepatic encephalopathy.

Abstract
Bipolar disorder (BD) is highly heritable and associated with dysregulation of brain glucose utilizations (GU). The mitochondrial DNA (mtDNA) 10398A polymorphism, as a reported BD risk factor, leads to deficient glycolytic energy production by affecting mitochondrial matrix pH and intracellular calcium levels. However, whether mtDNA-10398A has functional effects on the brain and how our body responds remain elusive. We compared peripheral and central glucose-utilizing patterns between mtDNA A10398G polymorphisms in BD and their unaffected siblings (BDsib). Since siblings carry identical mtDNA, we hypothesized that certain characteristics co-segregate in BD families. We recruited twenty-seven pairs of non-diabetic BD patients and their BDsib and 30 well-matched healthy control subjects (HC). The following were investigated: mtDNA, fasting plasma glucose/insulin, cognitive functions including Montreal Cognitive Assessment (MoCA), and brain GU at rest. Insulin resistance was rechecked in sixty-one subjects (19-BD, 18-BDsibib, and 24-HC) six months later. We found that BD-pairs (BD+BDsib) carried more mtDNA-10398A and had higher fasting glucose, even after controlling for many covariates. BD-pairs had abnormally lower dorso-prefrontal-GU and higher cerebellar-GU, but only BD demonstrated lower medio-prefrontal-GU and MoCA. Subjects carrying mtDNA-10398A had significantly lower prefrontal-GU (FWE-corrected p<0.05). An abnormal inverse pattern of insulin-GU and insulin-MoCA correlation was found in BD-pairs. The insulin-MoCA correlation was particularly prominent in those carrying mtDNA-10398A. mtDNA-10398A predicted insulin resistance 6 months later. In conclusion, mtDNA-10398A was associated with impaired prefrontal-GU. An up-regulation of glucose utilizations was found in BD-pairs, probably compensating for mtDNA-10398A-related energy loss.

Abstract
BACKGROUND Previous evidence has shown positive associations between post-traumatic stress disorder (PTSD) and hypertension, dyslipidaemia and diabetes mellitus, which are all risk factors for stroke, but the role of PTSD in the subsequent development of stroke is still unknown. AIMS To investigate the temporal association between PTSD and the development of stroke. METHOD Identified from the Taiwan National Health Insurance Research Database, 5217 individuals aged ≥18 years, with PTSD but with no history of stroke, and 20 868 age- and gender-matched controls were enrolled between 2002 and 2009, and followed up until the end of 2011 to identify the development of stroke. RESULTS Individuals with PTSD had an increased risk of developing any stroke (hazard ratio (HR) 3.37, 95% CI 2.44-4.67) and ischaemic stroke (HR = 3.47, 95% CI 2.23-5.39) after adjusting for demographic data and medical comorbidities. Sensitivity tests showed consistent findings (any stroke HR = 3.02, 95% CI 2.13-4.28; ischaemic stroke HR = 2.89, 95% CI 1.79-4.66) after excluding the first year of observation. CONCLUSIONS Individuals with PTSD have an increased risk of developing any stroke and ischaemic stroke. Further studies are required to investigate the underlying mechanisms.

Abstract
Background Although the comorbidity between migraine and major depressive disorder (MDD) has been recognized, the pathophysiology remains unclear. The dorsolateral prefrontal cortex (DLPFC) is a well-known neural substrate for MDD. We investigated the relationship between brain metabolites in DLPFC and comorbid MDD in migraine patients. Methods We recruited migraine patients from a tertiary headache clinic. A board-certified psychiatrist conducted a structured interview for MDD diagnosis. The severity of depression was evaluated by the Beck Depression Inventory (BDI). Thirty migraine patients (five men, 25 women; mean age: 40.4 ± 12.4 years) completed the study, and 16 of them were diagnosed with MDD. All patients underwent a magnetic resonance spectroscopy (MRS) examination focusing on bilateral DLPFC. The ratios of N-acetylaspartate (NAA), choline (Cho), and myo-inositol (mI) to total creatine (tCr) were compared between migraine patients with and without MDD, and were correlated with BDI scores. Results Relative to patients without MDD, migraine patients with MDD had higher mI/tCr ratios in the bilateral DLPFC ( p = 0.02, left; p = 0.02, right, Mann-Whitney U test). The mI/tCr ratios in the right DLPFC were positively correlated with BDI scores ( r = 0.52, p = 0.003). The NAA/tCr and Cho/tCr ratios did not differ between migraine patients with and without MDD. Conclusion Increased mI/tCr within the DLPFC might be associated with the presence of MDD in migraine patients.

Abstract
BACKGROUND Studies have shown that chronic inflammation may play a vital role in the pathophysiology of both gastroesophageal reflux disease (GERD) and bipolar disorder. Among patients with GERD, the risk of bipolar disorder has not been well characterized. OBJECTIVE We explored the relationship between GERD and the subsequent development of bipolar disorder, and examined the risk factors for bipolar disorder in patients with GERD. METHODS We identified patients who were diagnosed with GERD in the Taiwan National Health Insurance Research Database. A comparison cohort without GERD was matched according to age, sex, and comorbidities. The occurrence of bipolar disorder was evaluated in both cohorts based on diagnosis and the prescription of medications. RESULTS The GERD cohort consisted of 21,674 patients, and the comparison cohort consisted of 21,674 matched control patients without GERD. The incidence of bipolar disorder (incidence rate ratio [IRR] 2.29, 95% confidence interval [CI] 1.58-3.36, P<.001) was higher among GERD patients than among comparison cohort. Multivariate, matched regression models showed that the female sex (hazard ratio [HR] 1.78, 95% CI 1.76-2.74, P = .008), being younger than 60 years old (HR 2.35, 95% CI 1.33-4.16, P = .003), and alcohol use disorder (HR 4.89, 95% CI 3.06-7.84, P = .004) were independent risk factors for the development of bipolar disorder among GERD patients. CONCLUSIONS GERD may increase the risk of developing bipolar disorder. Based on our data, we suggest that attention should be focused on female patients younger than 60 years, and patients with alcohol use disorder, following a GERD diagnosis.

Abstract
BACKGROUND Previous studies have suggested an association between asthma and dementia, but the results are still inconsistent. METHODS Using the Taiwan National Health Insurance Database, we enrolled 11,030 participants aged more than 45 years with asthma and 44,120 (1:4) age-/sex-matched controls between 1998 and 2008, and followed them to the end of 2011. Cases of any dementia or Alzheimer's disease that developed during the follow-up period were identified. RESULTS Asthma was associated with an increased risk of developing any dementia [hazard ratio (HR): 2.17, 95% confidence interval (CI): 1.87-2.52] and Alzheimer's disease (HR: 2.62, 95% CI: 1.71-4.02). Stratified by age, both asthma in midlife (>45 years and <65 years) and in late life (≥65 years) was associated with a greater likelihood of any dementia (HR: 2.48, 95% CI: 1.80-3.41; HR: 2.06, 95% CI: 1.74-2.44). DISCUSSION Asthma in midlife and in late life increased the risk of developing any dementia and Alzheimer's disease. The underlying mechanisms between asthma and dementia require further investigation.

Abstract
The ATP-binding cassette, subfamily A, member 7 gene (ABCA7) was recently identified as a susceptible gene of Alzheimer's disease (AD) in the Caucasian population and African Americans. To test its genetic effect in the Han-Chinese population, 536 AD cases and 307 cognitive-intact, elder controls were genotyped for ABCA7 rs3764650 and apolipoprotein E (APOE) ε2/ε3/ε4 alleles. Global cognitive performance was assessed by the Mini-Mental State Examination in both AD patients and controls. For AD patients, comprehensive evaluation of each cognitive domain was further conducted as the following: (1) attention (forward and backward digit span); (2) memory (12-item word recall test); (3) executive function (category verbal fluency); (4) processing speed (Trail making test, part A); and (5) naming task (Boston naming test). ABCA7 rs3764650 was significantly associated with AD and the GG genotype carried a reduced risk for AD (odds ratio = 0.52, p = 0.0026). The association was further confirmed in 1802 population-based, healthy controls from Taiwan Biobank as a replicate (odds ratio = 0.70, p = 0.032). After adjustment of age, sex, and APOE ε4 allele, rs3764650 remained to be an independent predictor of AD (p = 0.001). The influence of ABCA7 was only evident in individuals without APOE ε4 alleles (p = 0.0004) but absent in ε4 carriers (p = 0.91). None of the cognitive tests was related to ABCA7 rs3764650 genotypes. The minor allele frequency and effect size of rs3764650 disclosed in the Han-Chinese population differed from those reported in the Caucasians and African Americans. Further studies were warranted to elucidate ABCA7's effect among different ethnic groups.

Abstract
BACKGROUND & AIMS To evaluate the risk of depressive disorders among non-alcoholic patients by using the Taiwan National Health Insurance Research Database (NHIRD). METHODS We conducted a retrospective study of a matched cohort of 52 725 participants (10 545 non-alcoholic cirrhotic patients and 42 180 control patients) who were selected from the NHIRD. Patients were observed for a maximum of 11 years to determine the rates of newly onset depressive disorders, and Cox regression was used to identify the risk factors associated with depressive disorders in cirrhotic patients. RESULTS During the 11-year follow-up period, 395 (3.75%) non-alcoholic cirrhotic patients and 1 183 (2.80%) control patients were diagnosed with depressive disorders. The incidence risk ratio of depressive disorders between non-alcoholic cirrhotic patients and control patients was 1.76 (95% CI, 1.57-1.98, P<.001). After adjusting for age, sex, and comorbidities, non-alcoholic cirrhotic patients were 1.75 times more likely to develop depressive disorders (95% CI, 1.56-1.96, P<.001) compared with the control patients. The hazard ratios for patients younger than 60 years old (1.31) and female (1.25) indicated that each is an independent risk factor for depressive disorders in non-alcoholic cirrhotic patients. CONCLUSIONS The likelihood of developing depressive disorders is greater among non-alcoholic cirrhotic patients than among patients without cirrhosis. Symptoms of depression should be sought in patients with cirrhosis.

Abstract
OBJECTIVE The association between selective serotonin receptor inhibitors (SSRIs) and risk of upper gastrointestinal bleeding remains controversial. Previous studies have generally evaluated the issue for approximately 3 months, even though the SSRI-mediated inhibition of platelet serotonin concentrations occurs within 7-14 days. The authors explored the risk of upper gastrointestinal bleeding after short-term SSRI exposure by a case-crossover design. METHOD The records of psychiatric inpatients with upper gastrointestinal bleeding were retrieved from the Taiwan National Health Insurance Database (1998-2009). Rates of antidepressant use were compared for case and control periods with time windows of 7, 14, and 28 days. The adjusted self-matched odds ratios from a conditional logistic regression model were used to determine the association between SSRI use and upper gastrointestinal bleeding. RESULTS A total of 5,377 patients with upper gastrointestinal bleeding were enrolled. The adjusted odds ratio for the risk of upper gastrointestinal bleeding after SSRI exposure was 1.67 (95% CI=1.23-2.26) for the 7-day window, 1.84 (95% CI=1.42-2.40) for the 14-day window, and 1.67 (95% CI=1.34-2.08) for the 28-day window. SSRIs with high and intermediate, but not low, affinity for serotonin transporter were associated with upper gastrointestinal bleeding. An elevated risk of upper gastrointestinal bleeding after SSRI exposure was seen in male but not female patients. CONCLUSIONS Short-term SSRI use (7-28 days) is significantly associated with upper gastrointestinal bleeding. Gender differences may exist in the relationship between SSRI use and upper gastrointestinal bleeding. Physicians should carefully monitor signs of upper gastrointestinal bleeding even after short-term exposure to SSRIs, as is done with nonsteroidal anti-inflammatory drugs and aspirin.

Abstract
This study assessed the utility of multiscale entropy (MSE), a complexity analysis of biological signals, to identify changes in dynamics of surface electroencephalogram (EEG) in patients with Alzheimer's disease (AD) that was correlated to cognitive and behavioral dysfunction. A total of 108 AD patients were recruited and their digital EEG recordings were analyzed using MSE methods. We investigate the appropriate parameters and time scale factors for MSE calculation from EEG signals. We then assessed the within-subject consistency of MSE measures in different EEG epochs and correlations of MSE measures to cognitive and neuropsychiatric symptoms of AD patients. Increased severity of AD was associated with decreased MSE complexity as measured by short-time scales, and with increased MSE complexity as measured by long-time scales. MSE complexity in EEGs of the temporal and occipitoparietal electrodes correlated significantly with cognitive function. MSE complexity of EEGs in various brain areas was also correlated to subdomains of neuropsychiatric symptoms. MSE analysis revealed abnormal EEG complexity across short- and long-time scales that were correlated to cognitive and neuropsychiatric assessments. The MSE-based EEG complexity analysis may provide a simple and cost-effective method to quantify the severity of cognitive and neuropsychiatric symptoms in AD patients.

Abstract
BACKGROUND The aim of this study was to investigate the relationship between social engagement and daytime sleepiness among aged residents of a veterans' housing facility in Taiwan. METHODS A total of 597 men were enrolled in this cross-sectional study. Each subject was assessed with the Resident Assessment Instrument-Minimum Data Set, Geriatric Depression Scale, Pittsburgh Sleep Quality Index, and Mini-Mental State Examination. Social engagement was measured with the Index of Social Engagement (ISE), and daytime sleepiness was defined according to the relevant Pittsburgh Sleep Quality Index subcomponent. Subjects were divided into two groups according to their ISE levels. A multivariate logistic regression model was used to examine the association between ISE and other variables. RESULTS The sample's mean age was 80.8 ± 5.0 years (range: 65-99 years). Mean ISE score was 1.5 ± 1.3 (range 0-5), with 52% of participants reporting poor social engagement (ISE = 0-1). Mean Pittsburgh Sleep Quality Index global score was 5.6 ± 3.6 (range: 0-18), and 31% of participants reported daytime sleepiness. The analysis was adjusted for level of depression, cognitive impairment, dependence in activities of daily life, unsettled relationships, and illiteracy. After adjustment, daytime sleepiness was found to be independently associated with subjects' level of social engagement (odds ratio: 2.5; 95% confidence interval: 1.7-3.8; P < 0.001). CONCLUSIONS Daytime sleepiness and poor social engagement are common among aged residents of a veterans' housing facility. Subjects experiencing daytime sleepiness but not poor general sleep quality were at increased risk of poor social engagement. The clinical care of older residents must focus on improving daytime sleepiness to enhance their social engagement.

Abstract
Background Bupropion, which is widely used in patients with depressive disorder, may cause allergic reactions. However, the real prevalence of these side effects may be overlooked and underreported due to the delayed onset phenomenon. Objective This study aimed to estimate the real incidence of bupropion-induced urticaria and clarify the delayed onset phenomenon. Methods We conducted a nationwide cohort study between 2000 and 2009 using Taiwan’s National Health Insurance Dataset. Among 65,988 patients with depressive disorders, we identified new users of bupropion with depressive disorders (bupropion cohort, n = 2,839) and matched them at a ratio of 1:4 regarding age and sex (non-bupropion matched cohort, n = 11,356). The risk of urticaria was compared between the two cohorts. Results The risk of urticaria occurrence was higher in bupropion users than in matched controls within 4 weeks of starting the medication (risk ratio 1.81; 95% confidence interval 1.28–2.54; p = 0.001). The occurrence of urticaria in the bupropion cohort were more frequent on Days 15–28 than Day 1–14 (p = 0.002). Cox proportional hazards model showed that a history of urticaria was an independent risk factor for developing bupropion-induced urticaria. Conclusions Of the antidepressants, bupropion may pose a higher risk of drug-induced urticaria, and this condition might be ignored due to the delayed onset phenomenon. Depressive patients with a history of urticaria are at higher risk of the adverse drug reaction. This study emphasizes the need for increased clinical awareness of this adverse outcome to bupropion use.

Abstract
OBJECTIVES To evaluate the prevalence and the association of psychological disturbance in migraine patients with allodynia. METHODS We recruited 434 migraine patients from an outpatient clinic. The participants completed three self-administered questionnaires, including a headache questionnaire, an allodynia symptoms checklist, and the Hospital Anxiety and Depression Scale (HADS). RESULTS Among the migraineurs, 48.4% participants reported allodynia. The HADS total score (15.5 ± 7.8 vs. 13.7 ± 8.5, P = 0.022) and anxiety subscore (9.1 ± 4.5 vs. 7.6 ± 4.7, P = 0.001) were higher in migraineurs with allodynia than in those without allodynia. The anxiety subscore in patients with moderate to severe allodynia, mild allodynia, and no allodynia were 10.0 ± 4.5, 8.4 ± 4.3, and 7.6 ± 4.7 ( P < 0.001, by one-way analysis of variance). Among patients with moderate to severe allodynia, there was a trend of higher depression subscore (7.1 ± 4.0, P = 0.059) than those with no (6.1 ± 4.4) or mild allodynia (5.8 ± 4.0). In a regression model, the presence of allodynia is an independent risk factor for clinically significant anxiety. Moderate to severe allodynia is an independent risk factor for clinically significant depression. CONCLUSIONS In migraineurs, the severity of cutaneous allodynia was associated with their mood status, especially anxiety.

Abstract
OBJECTIVE Agitation and depression are among the commonest behavioural and psychological symptoms exhibited by Alzheimer's disease patients. However, their pathophysiology remains unclear. We therefore investigated the relationship between the brain metabolism in the posterior cingulate gyrus and the dorsolateral prefrontal cortex, and agitation and depression in patients diagnosed with Alzheimer's disease. METHODS We recruited 26 patients (14 women and 12 men) with a mean age of 75 years and probable Alzheimer's disease. All patients completed the Mini-Mental State Examination (MMSE), the Geriatric Depression Scale-Short Form (GDS) assessment, and the Cohen-Mansfield Agitation Inventory (CMAI) in order to evaluate cognition, depression, and agitation, respectively. All subjects underwent magnetic resonance imaging and (1)H-magnetic resonance spectroscopy of the brain. The ratios of N-acetylaspartate (NAA), choline (Cho), and myo-inositol (mI) to creatine (Cr) in the posterior cingulate gyrus and the dorsolateral prefrontal cortex were measured and compared with neuropsychological test results. RESULTS The MMSE scores correlated positively with the NAA/Cr ratio in the left posterior cingulate gyrus (r = 0.56; p = 0.001). The CMAI scores correlated negatively with the NAA/Cr ratio in the left posterior cingulate gyrus (r = -0.46; p = 0.02). The GDS scores correlated positively with the Cho/Cr ratio in the left dorsolateral prefrontal cortex (r = 0.59; p = 0.01), and mI/Cr in both left (r = 0.47; p = 0.03) and right (r = 0.47; p = 0.03) cingulate gyri. CONCLUSIONS Agitation and depression levels correlated with different neurochemical metabolites in specific brain areas. We conclude that various neuropsychiatric symptoms might have separate pathophysiologies.

Abstract
BACKGROUND Subcortical ischemic vascular dementia (SIVD) caused by small-artery disease, and hypoperfusion is a major cause of vascular cognitive impairment. Little is known about the relationship between sleep disturbance and white matter hyperintensity (WMH). We investigated the association between sleep disturbance and WMH, measured by magnetic resonance imaging (MRI), in patients with SIVD. METHODS Patients with SIVD recruited from our outpatient clinic completed the Sleep Disturbance Symptom Questionnaire (SDSQ) and Geriatric Depression Scale-short form (GDS-S) and underwent brain MRI. Total SDSQ scores were calculated by summing frequency ratings of the instrument's 20 items. We graded WMH on brain MR images using a visual rating scale ranging from 0 (barely detectable) to 9 (extensive changes). RESULTS We enrolled 72 patients (31 men, 41 women; mean age, 75.9 ± 7.9 years) with SIVD. The SDSQ scores were positively correlated with WMH grading (r = .337, P = .001) and tended to be associated with higher GDS-S scores (r = .268, P = .022). Patients with diabetes mellitus tended to display higher mean WMH severity than those without diabetes (4.2 vs 3.3, P = .022). After controlling for confounding factors, the multivariate regression model showed that WMH severity was significantly associated with sleep disturbance (P = .002). CONCLUSIONS This study showed that manifestations of sleep disturbance were significantly associated with WMH severity, with most symptoms related to daytime hypersomnolence. Disruption of the frontal-subcortical neuronal circuit might play a role in sleep disturbance in patients with SIVD.

Abstract
In 2009, more than 50% of vine type French beans were found bearing severe viral symptoms in a vegetable garden in Nantou County, Taiwan. Infected plants were stunted and exhibited pronounced mottling symptoms on their leaves. The symptomatic plants were mechanically inoculated on Chenopodium quinoa and local lesions developed 7 to 10 days after inoculation. The virus source established by back isolation the single lesion from C. quinoa on French beans developed symptoms similar to those found in the field. Host range test showed that this isolate could only infect leguminous plants, including soybean, mung bean, pea, peanut, asparagus bean, cowpea, adzuki bean, and lima bean, but not cucurbitaceous and solanaceous plants. Since only Cucumber mosaic virus (CMV) has been reported in Taiwan to induce similar symptoms in French beans, we tested both the field collected and inoculated French beans by CMV antiserum in ELISA but obtained a negative result. Due to subsequent electron microscopy studies that found potyvirus and carlavirus like particles in the leaf dips of infected French beans, we conducted reverse transcription (RT)-PCR using generic degenerate primers for potyviruses (Hrp5/Pot1 (2) and PotZ/Pot1 (3)) and carlaviruses (Decarla-u2 (5'-TGCACTGARTCMGAYTATGARGCYTT-3' and Decarla-d1 (5'-GCACATRTCRTCVCCDGCAAA-3') previously designed in our lab. No amplification was found from the potyvirus primers, while the carlavirus one gave an expected amplicon of 285 bp, which was found sharing 81% nucleotide sequence identity with the replicase gene of Cowpea mild mottle virus (CpMMV) (GenBank Accession No. FJ560903). A primer pair (CpMMV-CPu: 5'-TTTACTCTTAggTWATggAgTC-3' and CpMMV-CPd: 5'-CCTATTAAAACACACAAHTCAAA-3') was thus designed to amplify the complete coat protein (CP) gene based on the reported CP sequences and obtained an expected 867-bp product from our French bean isolate. This 867-bp sequence (JX020701) was confirmed to have 97.6% amino acid sequence identities with the CP gene of a Puerto Rican CpMMV isolate (GU191840). In a separate survey, another isolate from asparagus bean (CpMMV-V) causing mild mottling symptom was obtained. Analyses of the CP gene of CpMMV-V (JX070669) confirmed that it shared 88.8% and 97.8% of nucleotide and amino acid sequence identities with the French bean isolate, respectively. Different from most carlaviruses with aphid transmissibility, CpMMV has been shown to be transmitted non-persistently by whiteflies (1). Both CpMMV isolates from Taiwan were confirmed to be transmitted by silver leaf whiteflies (Bemicia argentifolii Bellows and Perring). This is the first record of whitefly transmissible legume virus in Taiwan. Since whitefly has been a problem in agriculture worldwide, CpMMV can be a new emerging threat for Taiwan's legume crop production. References: (1) M. Iwaki et al. Plant Dis. 66:365, 1982. (2) S. S.

Abstract
OBJECTIVE The objective of this study is to assess the incidence and risk of mood disorders, including major depression, anxiety, and bipolar disorders, in Taiwanese patients after the diagnosis of breast cancer compared with a matched cohort. METHODS From January 2000 to December 2005, 26,629 newly diagnosed breast cancer patients were enrolled by the Taiwan National Health Insurance program database. The control cohort was selected randomly from 1,000,000 National Health Insurance beneficiaries from a population of 21,400,826 enrolled throughout Taiwan. Each patient was matched with one subject without breast cancer by age, sex, and presence of comorbidities with the same diagnosis index date. The diagnosis of mood disorders was defined by compatible International Classification of Diseases, 9th revision, clinical modification codes plus the prescription of antidepressants for at least 30 days. RESULTS The overall incidence rate ratio of mood disorders was 1.33 (95% CI 1.28-1.39, p < 0.001) in the breast cancer cohort compared with the matched cohort. The incidence rate ratios for specific mood disorders were 2.06 for bipolar disorder (95% CI 1.37-3.15 p = 0.0003), 1.94 for major depressive disorder (95% CI 1.76-2.13 p < 0.001), and 1.22 for anxiety (95% CI 1.16-1.27 p < 0.001). Independent risk factors for developing mood disorders included breast cancer, as well as age, hypertension, chronic obstructive pulmonary disease, autoimmune disease, ischemic heart disease, and cerebrovascular disease. CONCLUSIONS Breast cancer is a prominent risk factor for mood disorders, including major depressive disorder, anxiety, and bipolar disorder. The impact is most potent in the first year after diagnosis. Psychological support is a critical issue in these patients.

Abstract
OBJECTIVE To evaluate the risk of cancer among patients with generalized anxiety disorder (GAD) in a nationwide population-based dataset. METHODS We recruited newly-diagnosed GAD patients aged 20 years or older without antecedent cancer from the Taiwan National Health Insurance Research database between 2000-2010. Standardized incidence ratios (SIRs) of cancers were calculated in GAD patients, and the subgroup of GAD patients diagnosed by psychiatric specialists. RESULTS A total of 559 cancers developed among 19,793 GAD patients with a follow-up of 89,485 person-years (median follow-up of 4.34 years), leading to a significantly increased SIR of 1.14 [95% confidence interval (CI) 1.05-1.24]. Male GAD patients had a significantly increased SIR overall (1.30, 95% CI 1.15-1.46) and for lung and prostate cancer (1.77, 95% CI 1.33-2.30 and 2.17, 95% CI 1.56-2.93, respectively). Patients over 80 years of age also had a significantly increased SIR (1.56, 95% CI 1.25-1.92), especially in males. However, psychiatrist-diagnosed GAD patients did not show increased cancer risk relative to the general population, perhaps due to having fewer physical comorbidities than non-psychiatrist-diagnosed GAD patients. CONCLUSION This study found that overall cancer risk is elevated among patients with GAD. The risk of lung and prostate cancer also increased in male patients with GAD. This increased cancer risk may be due to physical comorbidities and surveillance bias. Further prospective study is necessary to confirm these findings.

Abstract
OBJECTIVE To compare the effectiveness of the Minimum Data Set-based Depression Rating Scale (MDS-DRS) and Geriatric Depression Scale (GDS) in screening depression among older institutionalized Chinese men living in Taiwan. METHOD MDS Nursing Home 2.1 Chinese version, Mini-Mental State Examination (MMSE), and short form Geriatric Depression Scale (GDS-15) were used among elderly residents in Banciao Veterans Home. Screening results of MDS-DRS and GDS-15, and relationship between 16 MDS Mood and Anxiety symptoms and depression were evaluated. RESULTS The prevalence of depression defined by MDS-DRS and GDS were 0.2% and 8.7%, respectively. Multiple logistic regression disclosed that E1a (OR: 12.9, 95% CI: 2.8-58.8, p = 0.001), E1k (OR: 15.6, 95% CI: 5.6-43.5, p < 0.001), and E1l (OR: 22.2, 95% CI: 6.1-83.3, p < 0.001) were all independent associative factors for GDS-defined depression but only explained 51.9% of all depressive subjects. CONCLUSIONS The effectiveness of MDS-DRS is limited, and a new MDS-based depression screening instrument is needed.

Abstract
AIMS Previous research has suggested that patients with interstitial cystitis have more sleep disturbances and higher levels of depression. However, reports that employ validated sleep questionnaires are rare for this population. The present study investigates the relationship between sleep quality, anxiety, depression, and the severity of urologic interstitial cystitis symptoms in outpatients, and risk factors for poor sleep quality. METHODS A total of 69 patients (52 female) with interstitial cystitis met National Institute of Arthritis, Diabetes, Digestive and Kidney Diseases (NIDDK) criteria, completed all instruments. The O'Leary-Sant Interstitial Cystitis Symptom Index (ICSI) was performed to assess interstitial cystitis severity. The Pittsburgh Sleep Quality Index (PSQI) and Hospital Anxiety and Depression Scale (HADS) were used to evaluate quality of sleep and depression level, respectively. Multiple linear regressions were used to identify independent factors of sleep quality. RESULTS Mean PSQI global score was 9.5 +/- 4.2 (range: 1-19); 81.2% of subjects had poor sleep quality (PSQI > 5). Regression analysis suggested that the severity of interstitial cystitis (Beta coefficient = 0.42, P < 0.001) and level of anxiety and depression (Beta coefficient = 0.26, P < 0.05) were significant independent risk factors for poor sleep quality, after controlling for age, gender, marital status, years of education, and years of symptomatic duration. Further analysis of ICSI subdomain scores shows that association between nighttime urination and poor sleep quality remains significantly (Beta coefficient = 0.32, P < 0.05), after adjustment for demographic data and anxiety and depression. CONCLUSIONS Poor sleep quality is common in interstitial cystitis patients and severity of urological symptoms and depression levels are important independent risk factors.

Abstract
Late-onset major depression is thought to have a biological (vascular) basis, which could be a result of brain structure change. Vascular lesions can affect both the gray matter (GM) and white matter (WM), while most previous studies addressed WM abnormality. This study explored the disease- and symptom (history of suicide attempt) -related GM morphometry in elderly male patients with late-onset depression. A total of 70 patients with depression admitted to our geriatric psychiatric ward were investigated, and 26 age-matched males were recruited as controls. We used T1-weighted magnetic resonance imaging (MRI) to obtain cerebral structural information and adopted voxel-based morphometry (VBM) to investigate brain volume change related to disease (depression vs control) and symptom (depression with history of suicide attempt vs depression without history of suicide attempt). Late-onset depression was associated with smaller volumes in several regions of GM (insula and the posterior cingulate region) and WM (subcallosal cingulate cortex, floor of lateral ventricles, parahippocampal region, insula, and the cerebellum). Compared with nonsuicidal counterpart, suicidal depression was associated with decreased GM and WM volume in the frontal, parietal, and temporal regions, and the insula, lentiform nucleus, midbrain, and the cerebellum. Marked regional volume reduction was noticed at dorsal medial prefrontal cortex. Our results demonstrate that the development of suicidal behaviors in major depression is related to widespread but discrete volume reduction in several cortical and subcortical structures, fitting with the hypothesis that decreased cerebral volume in certain regions renders biological susceptibility to attempt suicide during depressive states.

Abstract
AIM Alzheimer's disease (AD) is characterized by cognitive symptoms and behavioral symptoms, and their association is inconsistent. The aim of this study was to investigate the relationship between cognitive function and the changes in behavioral and psychological symptoms of dementia (BPSD) in patients with AD. METHODS A total of 101 patients with probable AD were enrolled (57 women and 44 men, mean age 77.6 +/- 7.7 years). The Category Verbal Fluency Test (CVFT), the Mini-Mental State Examination (MMSE), the Constructional Praxis Test, the Delayed Word Recall Test, the Clinical Dementia Rating Scale, and the Neuropsychiatry Inventory (NPI) were administered at baseline. The NPI was reassessed with a median follow-up duration of 10 months (range 6-18 months). The change in the NPI scores was defined as the end-point score of the NPI minus the initial one. The associations between the changes in NPI total score, its four subdomains (hyperactivity, psychosis, affection, and apathy), and cognitive function were examined using multivariate linear models. The results were adjusted for confounders including demographics, baseline NPI, and duration of follow up. RESULTS The mean MMSE was 18.6 +/- 5.6, the CVFT score was 7.1 +/- 3.9, and the NPI score was 10.9 +/- 13.8. Regression analyses found that the CVFT score (beta = -0.32, P = 0.004) was significantly associated with the change in NPI score, but not the MMSE, the Delayed Word Recall score, or the Constructional Praxis score. The CVFT score was significantly associated with changes in the psychosis subdomain (beta = -0.34, P = 0.001), but not the other subdomains. CONCLUSIONS Our study showed that CVFT was predictive of the changes in behavior disturbance in patients with AD, particularly in the psychosis domain.

Abstract
The striking influence of the growth kinetics and substrate enhanced surface mobility on the control of the self-assembly of rare earth tantalate particles (1.5 mol% of nanoparticles in YBa(2)Cu(3)O(7) thin films) is demonstrated. Strongly enhanced flux pinning, control of the anisotropy property and superior critical current densities were achieved. Owing to the unique ability to probe nanoparticle self-assembly through determination of the nature and extent of the anisotropy of the superconducting properties, this system serves as the perfect model system for understanding how to tune and control functional nanocomposite nanostructures for a wide range of multifunctional applications.

Abstract
BACKGROUND Social engagement prolongs the lifespan and preserves cognition in the elderly. However, most studies concerning social engagement have been conducted in Western countries; few have been performed in the Chinese population. This study attempted to identify the risk factors for poor social engagement among elderly veterans in Taiwan. METHODS A total of 597 male veterans were enrolled, with a mean age of 80.8 +/- 5.0 years. This cross-sectional study employed the Resident Assessment Instrument (RAI) Minimum Data Set (MDS), the Geriatric Depression Scale-Short Form (GDS-SF), and the Mini-Mental State Examination (MMSE). Multivariate logistic regression analysis was done to investigate significant independent risk factors for poor social engagement, which were identified using the MDS Index of Social Engagement (ISE). RESULTS Mean ISE score was 1.5 +/- 1.3 (range, 0-5); 52% of subjects had poor levels of social engagement (ISE < 2; 312/597). Regression analyses suggested that depression (OR, 6.6; 95% CI, 2.7-16.1; p < 0.001), illiteracy (OR, 2.2; 95% CI, 1.3-3.8; p = 0.003), the presence of unsettled relationships (OR, 3.6; 95% CI, 1.5-8.7; p = 0.004), and cognitive impairment (OR, 2.0; 95% CI, 1.1-3.9; p = 0.03) were significant independent risk factors for poor social engagement, after controlling for age, marital status, level of daily living activity and degree of sensory impairment. CONCLUSION Poor social engagement is common among Chinese assisted-living veteran home residents. Depression is the greatest risk factor of poor social engagement in this population.

Abstract
BACKGROUND To assess the screening abilities of the Chinese (Taiwan) version of the Social Phobia Inventory (SPIN) for evaluating social phobia in an adolescent community sample. METHODS A total of 3,393 students (1,669 boys, 1,724 girls), aged 13-15, completed the SPIN questionnaire. A total of 144 students were enrolled for validity. The Mini-International-Neuropsychiatric-Interview-Kid (MINI-Kid) was used to establish Diagnostic and Statistical Manual of Mental Disorders-IV diagnosis. RESULTS The mean SPIN total score of all subjects was 14.2 +/- 9.4, which was higher in girls than in boys (14.7 +/- 9.4 vs. 13.7 +/- 9.1; p < 0.01). The 7th graders had the highest SPIN total scores compared with the 8th and 9th graders (15.4 +/- 9.7 vs. 13.4 +/- 9.1 and 14.0 +/- 9.4; p < 0.001). Internal consistency (Cronbach's alpha = 0.85) and test-retest reliability (r = 0.73) were both good. A cut-off score of 25 resulted in balanced sensitivity (80%) and specificity (77%). CONCLUSION The Chinese (Taiwan) SPIN has good screening abilities. The cut-offs are different from those in other countries, and highlight the importance of culturally adapted cut-offs.

Abstract
In this paper, we report the design of a system equipped with a multielement thermopile for measuring the temperature of a given plane. We evaluate the performance of our measurement system, which comprises a microcontroller, an analog-to-digital converter, a liquid crystal display (LCD), light-emitting diodes (LEDs), a buzzer, laser pointers, and a rotary encoder. We use different types of display modes such as an LCD for displaying the measured temperature, LEDs which colors indicate the temperature range, and an RS-232 or a wireless interface that transmits the temperature values to be displayed as different colors on a PC screen. The buzzer/alarm in the system is activated when the threshold temperature is reached. The system is inexpensive, portable, and can be used for two-dimensional temperature measurements; further, its emissivity can be easily adjusted. The effective detection range of this system is from -20 to 115 degrees C, and the field of view is 41 degrees x32 degrees ; the measurement error is confined to +/-1 degrees C. The experimental results demonstrate the effectiveness of the system in monitoring the temperature of a remote plane. Hence, it is possible to identify a hot spot that occurred in the electrical heating equipment or a smoldering source hidden in upholstery.

Abstract
OBJECTIVE Suicide attempt is rarely reported in dementia. This study explores the clinical and phenomenological aspects as well as the treatment of Chinese demented patients who have attempted suicide. METHODS During a 1-year period, demented patients admitted to a geropsychiatric unit as a result of suicide attempt were investigated for factors related to suicide attempt, such as motives and method. RESULTS In this 1-year survey, seven demented patients (11.7% of all demented patients) were admitted immediately following a suicide attempt. All seven patients had mild or moderate dementia. Three had significant clinical depression symptoms on admission. In all patients, delusions were the primary cause of suicide attempt. Their suicidal ideations were improved with antipsychotic and antidepressant treatment. CONCLUSION These cases, taken together, suggest that suicide attempt can occur in patients with dementia. It is important for clinicians to be aware of the risk of suicide in patients with dementia, especially those associated with delusions, even if they have no major depression or suicide attempt history. Antidepressants and antipsychotics may play a critical role in the treatment of suicide attempt in dementia.

Abstract
BACKGROUND Little is known about the prevalence of specific depressive and anxiety disorders in women before a new course of assisted reproductive technology treatment. Few studies have adopted the proper psychiatric diagnostic procedures. METHODS All consecutive women visiting the assisted reproduction clinic of a university-affiliated medical centre, with the intention of starting a new assisted reproduction treatment course, were recruited. A psychiatrist made a diagnosis of psychiatric disorders using a structured interview, the Mini-International Neuropsychiatric Interview (MINI). RESULTS Of a total of 112 participants, 40.2% had a psychiatric disorder. The most common diagnosis was generalized anxiety disorder (23.2%), followed by major depressive disorder (17.0%), and dysthymic disorder (9.8%). Participants with a psychiatric morbidity did not differ from those without in terms of age, education, income, or years of infertility. Women with a history of previous assisted reproduction treatment did not differ from those without in depression or anxiety. CONCLUSIONS Depressive and anxiety disorders were highly prevalent among women who visited an assisted reproduction clinic for a new course of the treatment. Demographic features and a history of previous assisted reproduction treatment were not risk factors for these psychiatric morbidities in the assisted reproduction clinic.

Abstract
The modulation of cytochrome P-450 2B1 expression by alpha-tocopheryl succinate and whether prostaglandin E2 is involved in this modulation in primary rat hepatocytes in the presence of phenobarbital were investigated. A primary rat hepatocyte culture model that faithfully reproduces the phenobarbital response observed in vivo was used. Intracellular alpha-tocopherol content was dose dependently increased by alpha-tocopheryl succinate incubation. Hepatocytes were demonstrated to have prostaglandin E2-synthesizing capability. alpha-Tocopheryl succinate inhibited prostaglandin E2 synthesis by hepatocytes and increased cytochrome P-450 2B1 expression in the presence of phenobarbital; however, it had little effect on intracellular cAMP level. To mimic the exogenous source of prostaglandin E2 from nonparenchymal cells, various concentrations of prostaglandin E2 were added to the cell culture. High doses of exogenous prostaglandin E2 (100 and 1,000 nM) inhibited the cytochrome P-450 2B1 expression in the presence of phenobarbital compared with low doses (1 and 10 nM); however, the presence of high doses of prostaglandin E2 had no effect on intracellular cAMP level. Forskolin significantly increased intracellular cAMP level and inhibited cytochrome P-450 2B1 expression in the presence of phenobarbital. The results of this study indicate that alpha-tocopheryl succinate increases cytochrome P-450 2B1 expression via its inhibition of prostaglandin E2 synthesis in the presence of phenobarbital; however, changes in intracellular cAMP level are not related to cytochrome P-450 2B1 expression.

Abstract
INTRODUCTION Coexistence of double tachycardias in one patient has been infrequently reported. Furthermore, the mechanisms of transition between double paroxysmal supraventricular tachycardias have not been well studied. METHODS AND RESULTS Thirty-five patients with two paroxysmal supraventricular tachycardias were studied. Group IA consisted of 3 patients with spontaneous transition between AV reciprocating tachycardia (AVRT) and AV nodal reentrant tachycardia (AVNRT). Group IB consisted of 13 patients without spontaneous transition between AVRT and AVNRT. Group IIA consisted of 5 patients with spontaneous transition between AVNRT and atrial tachycardia (AT). Group IIB consisted of 14 patients without spontaneous transition between AVNRT and AT. The absolute values of differences between the two tachycardia cycle lengths were significantly smaller in patients with than in those without transition between the two tachycardias (25+/-8 msec vs 90+/-46 msec, P < 0.05, IA vs IB; 21+/-25 msec vs 99+/-57 msec, P < 0.01, IIA vs IIB). The cutoff point of 25 msec had 80% positive predictive value for transition between the two tachycardias. Transition between two tachycardias occurred due to a spontaneous premature atrial complex (30%), conduction block at one limb of tachycardia (20%), or tachycardia-induced tachycardia (50%). Absence of transition between two tachycardias might be explained by the absence of a spontaneous premature atrial complex, longer cycle length of the first tachycardia, larger difference between two tachycardia cycle lengths, or induction of each tachycardia under different situations. CONCLUSION Double supraventricular tachycardias with similar tachycardia cycle lengths are vulnerable to transition between different tachycardias.

Abstract
BACKGROUND The atrial musculature in the cavotricuspid isthmus is a part of posterior inputs to the AV node. In patients with typical atrial flutter, effects of radiofrequency ablation of this isthmus on AV node conduction are still unknown. METHODS AND RESULTS This study included 16 patients with clinically documented typical atrial flutter. Group 1 had 8 patients without and group 2 had 8 patients with dual AV nodal pathway physiology. Electrical pacing from the interatrial septum and low right atrium was performed to evaluate antegrade AV node function before and after ablation of the cavotricuspid isthmus. In group 1, the AV node conduction properties were similar before and after ablation. In group 2, the AV node Wenckebach cycle length and maximal AH interval during low right atrium (356+/-58 versus 399+/-49 ms, P=0.008; 303+/-57 versus 376+/-50 ms, P=0.008) and interatrial septum (365+/-62 versus 393+/-59 ms, P=0.008; 324+/-52 versus 390+/-60 ms, P=0.008) pacing were significantly longer after ablation. Elimination of the slow pathway after ablation was noted in 2 patients, including 1 with AV nodal reentrant echo beats. CONCLUSIONS Radiofrequency ablation of the cavotricuspid isthmus was effective in eliminating typical atrial flutter without injury of antegrade fast AV node conduction. The atrial musculature in the cavotricuspid isthmus significantly contributed to the slow AV node conduction.
