Effectiveness of oral health promotion program for persons with severe mental illness: a cluster randomized controlled study.

OBJECTIVE: To evaluate the effectiveness of a composite oral health promotion program designed to reduce dental plaque among persons with severe mental illness in a psychiatric institution. METHODS: A cluster randomized controlled study was carried out in chronic psychiatric wards of a general hospital in central Taiwan. Sixty-eight eligible male individuals admitted to 2 wards were randomly assigned to an experimental and a control group. Participants in the experimental group underwent an oral health promotion program that consisted of biweekly group education sessions, and a 12-week individual behavioral modification for oral hygiene course. The participants in the control group received usual care only. Dental plaque (measured by the Plaque Control Index) was examined by a single dentist before and after the experiment. Each participant responded to a questionnaire regarding oral health knowledge, attitude and behavior before and after the experiment. RESULTS: Fifty-eight individuals completed the study. Before the experiment, the plaque index was similar between the intervention group (68.9; N = 27) and the control group (69.8; N = 31). After the experiment, the plaque index was significantly better in the intervention group than in the control group (42.6 vs. 61.8; P < 0.001). Participants in the intervention group also demonstrated better oral health knowledge, attitude and behavior than those in the control group after the experiment. CONCLUSIONS: A composite oral health promotion program using both group education and individual behavioral methods over a 12-week period was effective in both reducing dental plaque and improving the oral health knowledge of persons with severe mental illness in the institution. TRIAL REGISTRATION: This study was retrospectively registered in Clinicaltrials.gov, with number NCT04464941, dated 7/7/2020. https://register.clinicaltrials.gov/RD103035018 .

Gender difference in the association and presentation of visual hallucinations in dementia with Lewy bodies: a cross-sectional study.

OBJECTIVE: Visual hallucinations (VHs) are among the most striking features of dementia with Lewy bodies (DLB). We investigated gender differences in the association and presentation of VHs in DLB. METHODS: A cross-sectional analysis of baseline data from a prospective, longitudinal study on dementia was performed. Cumulative frequency, 1-month frequency, and phenomenology of VHs were summarized and compared between female and male patients with DLB. Gender differences in the factors associated with VHs were investigated in patients with and without hallucinations. RESULTS: A total of 152 patients including 65 (42.8%) women and 87 (57.2%) men were analyzed. The cumulative and 1-month frequencies of VHs were 60% and 55.4%, respectively, in women and 44.8% and 41.4%, respectively, in men. Adjusting for age and disease severity resulted in the inclusion of more women in the VH group [odds ratio (OR) = 2.33, p = 0.028)] than in the non-VH group. In female participants, older age (OR = 9.16, p = 0.003) and higher neuropsychiatric inventory score (OR = 4.89, p = 0.009) were associated with VHs, whereas in male participants, more severe dementia stage (clinical dementia rating 2-3 versus clinical dementia rating 0.5, OR = 6.22, p = 0.008) and higher rates of using antipsychotics (OR = 9.64, p = 0.047) were associated with VHs. CONCLUSION: The frequencies of 1-month and cumulative VHs were high in DLB, which indicated a high prevalence as well as a high persistency of VHs in DLB. The patterns of factors associated with VHs differed between female and male patients. Copyright © 2017 John Wiley & Sons, Ltd.

Variant GADL1 and response to lithium therapy in bipolar I disorder.

BACKGROUND: Lithium has been a first-line choice for maintenance treatment of bipolar disorders to prevent relapse of mania and depression, but many patients do not have a response to lithium treatment. METHODS: We selected subgroups from a sample of 1761 patients of Han Chinese descent with bipolar I disorder who were recruited by the Taiwan Bipolar Consortium. We assessed their response to lithium treatment using the Alda scale and performed a genomewide association study on samples from one subgroup of 294 patients with bipolar I disorder who were receiving lithium treatment. We then tested the single-nucleotide polymorphisms (SNPs) that showed the strongest association with a response to lithium for association in a replication sample of 100 patients and tested them further in a follow-up sample of 24 patients. We sequenced the exons, exon-intron boundaries, and part of the promoter of the gene encoding glutamate decarboxylase-like protein 1 (GADL1) in 94 patients who had a response to lithium and in 94 patients who did not have a response in the genomewide association sample. RESULTS: Two SNPs in high linkage disequilibrium, rs17026688 and rs17026651, that are located in the introns of GADL1 showed the strongest associations in the genomewide association study (P=5.50×10(-37) and P=2.52×10(-37), respectively) and in the replication sample of 100 patients (P=9.19×10(-15) for each SNP). These two SNPs had a sensitivity of 93% for predicting a response to lithium and differentiated between patients with a good response and those with a poor response in the follow-up cohort. Resequencing of GADL1 revealed a novel variant, IVS8+48delG, which lies in intron 8 of the gene, is in complete linkage disequilibrium with rs17026688 and is predicted to affect splicing. CONCLUSIONS: Genetic variations in GADL1 are associated with the response to lithium maintenance treatment for bipolar I disorder in patients of Han Chinese descent.

Utilization of dental care among patients with severe mental illness: a study of a National Health Insurance database.

BACKGROUND: The oral health of patients with severe mental illness is poor, in general, and this may be attributed, in part, to inadequate dental care. This study investigated dental care utilization among patients with severe mental illness using a national representative sample. METHODS: This study used Taiwan's National Health Insurance Research Dataset for 2009. Patients with the diagnosis of severe mental illness (ICD-9-CM: 290-298) were recruited as the study sample, and others comprised the control. Any visit to a dentist was defined as positive in terms of dental care utilization. Regression analyses were applied to determine the odds of dental care utilization for each diagnostic entity of severe mental illness, compared with the general population and controlling for potential covariates. RESULTS: Only 40 % of 19,609 patients with severe mental illness visited the dentist within 12 months. This was significantly lower than the dental visit rate of 48.3 % for the control population (odds ratio [OR] = .72, 95 % confidence interval [CI] = .69-.74; P <0.0001). The odds of dental care utilization differed among the severe mental illness diagnostic categories; e.g., the odds were lowest among those with alcohol psychoses (OR = .54, CI = .43-.68), senile dementia (OR = .55, CI = .52-.59) and other organic psychoses (OR = .58, CI = .52-.65), and highest among those with mood disorder (OR = .89, CI = .85-.94), with schizophrenic patients occupying a mid-level position (OR = .63, CI = .59-.67). CONCLUSIONS: Patients with severe mental illness received less dental care than the general population. Health care providers and caregivers of patients with severe mental illness should encourage them to visit the dentist regularly, in order to improve the oral health of these vulnerable patient groups.

Depressive symptoms as an independent risk factor for mortality in elderly persons: results of a national longitudinal study.

OBJECTIVE: Depressive symptoms have been associated with increased mortality risk in previous cohort studies, but there is a paucity of research on Asian elderly in recent years. The authors investigated the depression-mortality link using data from a representative national cohort. METHODS: Data came from the Survey of Health and Living Status of the Elderly in Taiwan. A cohort of 2416 men and women in Taiwan aged 65 or older were followed up for eight years from 1999 to 2007. Depressive symptoms were assessed by the 10-item Center for Epidemiologic Studies Depression Scale. The mortality risk of depression was computed after adjustment for a variety of covariates. Data on the presence or absence of chronic diseases were further analyzed. RESULTS: Overall, depressive symptoms were associated with all-cause mortality (hazard ratio (HR), 1.21; 95% confidence interval (CI), 1.03-1.42) after eight years follow-up, but this mortality risk was detected in men only (HR, 1.27; 95% CI, 1.03-1.56), not in women (HR, 1.1; 95% CI, 0.86-1.4). Further analyses showed that in the group without chronic diseases (without diabetes mellitus, stroke, lung disease, cancer, or cognitive impairment), depressive symptoms were associated with mortality (HR, 1.40; 95% CI, 1.12-1.76) after eight years follow-up; however, there was no association between depressive symptoms and mortality in participants with chronic diseases (HR, 1.02; 95% CI, 0.82-1.26). CONCLUSION: Depressive symptoms are an independent risk factor for mortality in the elderly. Elderly depressive men and elderly without chronic diseases seemed to have a greater mortality risk.

The impact of media reporting of the suicide of a singer on suicide rates in Taiwan.

PURPOSE: To examine if widespread media reporting of the suicide of a young female singer by charcoal burning increased suicide rates, and to examine whether the suicide induced a high risk of imitation suicide by this method among the young female group. METHODS: Poisson time series autoregression model was applied to examine the relative risk of overall and subgroup (age, gender and method) suicides during the 2-week period after the initiation of media reporting of the celebrity suicide. RESULTS: We found a significant increase (adjusted relative risk = 1.17, p = 0.04) in suicide deaths following media reporting of the celebrity suicide. The increase in suicides was particularly significant among female and young age groups. A marked increase in suicide by charcoal burning among females (adjusted relative risk = 1.44, p < 0.0001) was further observed. CONCLUSIONS: Detailed description of a specific suicide method following celebrity suicides may induce extensive modeling effect, attracting wider age/sex groups to model the method. Our finding provides further support for restraining media reporting of celebrity suicide in suicide prevention.

The influence of media reporting of a celebrity suicide on suicidal behavior in patients with a history of depressive disorder.

BACKGROUND: Few studies have directly assessed the impact of a specific media report in vulnerable people. This study investigates possible influences of media reporting of a celebrity suicide on subsequent suicidal behaviors and associated risk factors among depressive patients. METHODS: Depressive patients (N=461) were assessed through a structured interview soon after extensive media reporting of a celebrity suicide. RESULTS: Among 438 depressive patients exposed to the media report, 38.8% reported an influence on subsequent suicidal behaviors, including 24 (5.5%) with a suicide attempt. The risk of such influence was highest among patients in a severe depressive state just prior to the media report (adjusted OR 7.81, 95% CI 3.28-18.59). Such influence on a subsequent suicide attempt was highest in patients with a most recent suicide attempt within one month prior to the media reports (adjusted hazard ratio 11.91, 95% CI 3.76-37.72). LIMITATIONS: Our finding of the significant media influence may reflect adverse thoughts among more suicidal and depressed individuals. The possible influence of other factors on the findings cannot be ruled out. CONCLUSIONS: This study has provided more convincing evidence suggesting negative influences of media reporting of a celebrity suicide on subsequent suicidal behaviors among depressive patients. Particular attention in terms of potential negative media influences should be paid to patients who are younger and currently depressed and have made a recent suicide attempt.

Psychometric validations and comparisons of schizophrenia-specific health-related quality of life measures.

To compare schizophrenia-specific quality of life measures, this study examined an 18-item Chinese version of 41-item Quality of Life Questionnaire in Schizophrenia (S-QoL; S-QoL-18-C) using 41 patients. The S-QoL-18-C was validated and compared with Schizophrenia Quality of Life Scale-Revision 4 (SQLS-R4). Index scores of S-QoL-18-C showed nearly identical psychometrics to S-QoL-C and S-QoL-18. No significant ceiling/floor effects were found, except with psychological and selfesteem subscales. Internal consistency was acceptable for whole scale and all subscales, except family relationships and sentimental life. Test-retest reliability was moderate to high (ICC=0.58-87). Score distributions and reliability of S-QoL-18-C were slightly lower than those of S-QoL-C. Convergent validity was supported by satisfactory correlations between subscales/index scores of S-QoL-18-C and similar scales (r=∣-0.35 ∣ to 0.80) and between corresponding subscales in S-QoL-18-C and S-QoL-C (r=0.85-0.97). S-QoL-18-C and SQLS-R4 demonstrated discriminant validity by differentiating among 30 patients with symptom remission, 30 patients without symptom remission, and 30 healthy individuals. Two patient groups were classified by criteria proposed by Remission in Schizophrenia Working Group. Three groups were controlled for five factors. Furthermore SQLS-R4, but not S-QoL-18-C, differentiated between patient groups with different hospitalization frequencies. Overall, S-QoL-18-C and SQLS-R4 show different advantages psychometrically.

Change in depressive status and mortality in elderly persons: results of a national longitudinal study.

The authors aimed to investigate whether a change in depressive status was associated with a change in the risk of mortality in the elderly during a four-year follow-up period. Data came from the Survey of Health and Living Status of the Elderly in Taiwan. A cohort of 1784 men and women in Taiwan aged 65 or older who were assessed on two occasions in 1999 and 2003, and subsequently followed up until 2007. Depressive symptoms were assessed by the 10-item Center for Epidemiologic Studies Depression Scale (CES-D). The mortality risk of different depressive statuses was computed after adjustment for a variety of covariates. The data were further analyzed by gender and cause of death. Overall, chronic depression was associated with all-cause mortality (hazard ratio [HR], 1.66; 95% confidence interval [CI], 1.18-2.32) after 4 years of follow-up and controlling for covariates. When analyzing by gender, incident depression was associated with mortality in males only (HR=1.54; 95% CI=1.04-2.27). In females, only chronic depression was associated with a higher risk of mortality (HR=1.77; 95% CI=1.08-2.88). The increased risk of mortality with incident depression in males and chronic depression in females was attributed to non-cardiovascular disease (non-CVD) causes more than to CVD causes. In males, chronic depression predicted a higher incidence of CVD deaths. While chronic depression confers a greater risk of mortality in older women, incident depression predicts increased mortality in older men. The link between changing depressive status, gender, ethnicity and mortality warrants further investigation.

Oral health of psychiatric inpatients: a survey of central Taiwan hospitals.

OBJECTIVE: The objective was to investigate the status of oral health and its determinants in a group of psychiatric inpatients in central Taiwan. METHOD: A cross-sectional study of the oral health of psychiatric inpatients (n=200) in three hospitals in central Taiwan was carried out during a half-year period. Demographic data and data on oral health habits, dental visit frequency, treatment fear and dental health knowledge were collected. Oral health was determined by the Decayed/Missing/Filled Teeth (DMFT) index, Community Periodontal Index (CPI), Plaque Index and Gingival Index. RESULTS: In terms of prevalence of caries, the mean DMFT score for all patients was 14.9 ± 8.8 (S.D.), which was significantly worse than that in the general population. The CPI showed that only 10% of patients were periodontally healthy, 9.5% had bleeding, 31% had calculus and 49.5% had periodontal pockets. Increasing age, treatment anxiety, neglect of tooth-brushing and chronic ward inpatients were predictive factors for poor periodontal health. The self-awareness of poor oral health was inadequate and the treatment needs were huge in psychiatric inpatients. CONCLUSION: The oral health of psychiatric inpatients was poor compared with the general population and was generally ignored by the patients themselves. The phenomenon is universal, occurring in both Western and Eastern countries.

The influence of media coverage of a celebrity suicide on subsequent suicide attempts.

OBJECTIVE: To investigate the impact of media reporting of a celebrity suicide on subsequent suicide attempts. METHOD: A Poisson time series autoregression analysis was conducted to examine whether there was a significant increase in suicide attempts during the 3-week period after the start of extensive media reporting of a celebrity suicide. The reporting began on May 2, 2005, and lasted about 17 days. To investigate the influence of media reporting on suicide attempts, a structured interview was conducted with 124 suicide attempters identified from 2 counties in Mid Taiwan who had exposure to the media reporting. RESULTS: After controlling for seasonal variation, calendar year, temperature, and humidity, there was a marked increase in the number of suicide attempts during the 3-week period after media reporting began (adjusted relative risk = 1.55, 95% CI = 1.26 to 1.91). Among 124 suicide attempters exposed to the media reports, 23.4% reported an influence from them. There was no relationship between the attempters' ages and the age of the celebrity or the method, but male attempters had a significantly higher risk for such influence. A considerably higher risk for such influence was found among subjects with a history of suicide attempt(s) in the previous year (odds ratio = 52.3, 95% CI = 5.96 to 459.1). CONCLUSIONS: The extensive media reporting of the suicide of a celebrity was followed by an increase in suicide attempts. The effect was particularly marked in individuals with a recent history of a suicide attempt. The results provide further support for the need for more restrained reporting of suicides as part of suicide prevention strategies and for special vigilance for contagious effects of such reporting on people who have carried out recent suicidal acts.
