The associates of anxiety among lung cancer patients: Dehydroepiandrosterone (DHEA) as a potential biomarker.

OBJECTIVE: Anxiety is a prevalent comorbidity in lung cancer (LC) patients associated with a decline in quality of life. Dehydroepiandrosterone (DHEA), a neuroactive steroid, levels rise in response to stress. Prior research on the association between DHEA and anxiety has yielded contradictory results and no study has investigated this association in LC patients. METHODS: A total of 213 patients with LC were recruited from a general hospital. Data on demographic and cancer-related variables were collected. Using the Chinese version of the Hospital Anxiety and Depression Scale (HADS), the degree of anxiety was determined. Cortisol, DHEA, and Dehydroepiandrosterone sulfate (DHEA-S) levels in saliva were measured. Adjusting for confounding variables, a multivariate regression analysis was conducted. RESULTS: 147 men and 66 women comprised our group with an average age of 63.75 years. After accounting for demographic and treatment-related factors, anxiety levels were significantly correlated with, post-traumatic stress symptoms (PTSSs) (ß = 0.332, p < 0.001) and fatigue (ß = 0.247, p = 0.02). Association between anxiety and three factors, including DHEA, PTSSs, and fatigue, was observed in patients with advanced cancer stages (III and IV) (DHEA ß = 0.319, p = 0.004; PTSS ß = 0.396, p = 0.001; fatigue ß = 0.289, p = 0.027) and those undergoing chemotherapy (DHEA ß = 0.346, p = 0.001; PTSS ß = 0.407, p = 0.001; fatigue ß = 0.326, p = 0.011). CONCLUSIONS: The association between anxiety and DHEA remained positive in advanced cancer stages and chemotherapy patients. Further study is necessary to determine whether DHEA is a potential biomarker of anxiety in LC patients.

Association between maternal antidepressant use during pregnancy and the risk of autism spectrum disorder and attention deficit hyperactivity disorder in offspring.

Prenatal antidepressant exposure has been reported to be associated with adverse neurodevelopmental outcomes, yet studies considering confounding factors in Asian populations are lacking. This study utilized a nationwide data base in Taiwan, enrolling all liveborn children registered in the National Health Insurance system between 2004 and 2016. Subjects were divided into two groups: antidepressant-exposed (n = 55,707)) and antidepressant-unexposed group (n = 2,245,689). The effect of antidepressant exposure during different trimesters on autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) was examined. Sibling controls and parallel comparisons by paternal exposure status were treated as negative controls. Additional sensitivity analyses were conducted to examine the effects of antidepressant exposure before and after pregnancy. Prenatal antidepressant exposure was associated with increased risks of ASD and ADHD in population-wide and adjusted analysis. However when comparing antidepressant-exposed children with their unexposed siblings, no differences were found for ASD (Hazard ratio [HR]: 1.04, 95% confidence interval [CI] 0.76-1.42 in first trimester; HR: 0.96, 95% CI 0.62-1.50 in second trimester; HR: 0.69, 95% CI 0.32-1.48 in third trimester) and ADHD (HR: 0.98, 95%CI 0.84-1.15 in first trimester; HR: 0.91, 95% CI 0.73-1.14 in second trimester; HR: 0.79, 95% CI 0.54-1.16 in third trimester). Increased risks for ASD and ADHD were also noted in paternal control, before and after pregnancy analyses. These results imply that the association between prenatal antidepressant exposure and ASD and ADHD is not contributed to by an intrauterine medication effect but more likely to be accounted for by maternal depression, genetic, and potential environmental factors.

Neurobiological mechanisms of dialectical behavior therapy and Morita therapy, two psychotherapies inspired by Zen.

Psychotherapy is a learning process. Updating the prediction models of the brain may be the mechanism underlying psychotherapeutic changes. Although developed in different eras and cultures, dialectical behavior therapy (DBT) and Morita therapy are influenced by Zen principles, and both emphasize the acceptance of reality and suffering. This article reviews these two treatments, their common and distinct therapeutic factors, and their neuroscientific implications. Additionally, it proposes a framework that includes the predictive function of the mind, constructed emotions, mindfulness, therapeutic relationship, and changes enabled via reward predictions. Brain networks, including the Default Mode Network (DMN), amygdala, fear circuitry, and reward pathways, contribute to the constructive process of brain predictions. Both treatments target the assimilation of prediction errors, gradual reorganization of predictive models, and creation of a life with step-by-step constructive rewards. By elucidating the possible neurobiological mechanisms of these psychotherapeutic techniques, this article is expected to serve as the first step towards filling the cultural gap and creating more teaching methods based on these concepts.

Functional dyspepsia in depression: A population-based cohort study.

BACKGROUND: Patients with functional dyspepsia (FD) are more likely to have persistent depression, yet whether depression and antidepressant treatments are associated with subsequent risk of FD remain unclear. METHODS: Using population-based insurance administrative data of Taiwan, an 11-year historic cohort study was assembled, comparing cases aged 18 and above with the diagnosis of depressive disorder, to a propensity score-matched sample of adults without depression. Incident FD as a primary diagnosis was ascertained. Hazard ratios of FD were calculated using Cox regression models by age, gender, other comorbidities, nonsteroidal anti-inflammatory medications, antidepressants and antidiabetic agents. RESULTS: A total of 20,197 people with depressive disorder and 20,197 propensity score-matched comparisons without depression were followed up. The incidence of FD was 1.7-fold greater in the depressive cohort than in comparisons (12.9 versus 7.57 per 1000 person-years), with an adjusted hazard ratio (aHR) of 2.16 (95% confidence interval (CI) 1.93~2.41). Increased risks were significant regardless of comorbidities or medication uses, the highest in the untreated depression group compared to the group without depression, with an aHR of 2.51(95% CI 2.15~2.93). CONCLUSIONS: This population-based study showed that patients with depressive disorder are at elevated risk of FD. Antidepressant treatment could reduce the risk of FD.

Methylphenidate and mortality in children with attention-deficit hyperactivity disorder: population-based cohort study.

BACKGROUND: Little is known about methylphenidate (MPH) use and mortality outcomes. AIMS: To investigate the association between MPH use and mortality among children with an attention-deficit hyperactivity disorder (ADHD) diagnosis. METHOD: This population-based cohort study analysed data from Taiwan's National Health Insurance Research Database (NHIRD). A total of 68 096 children and adolescents aged 4-17 years with an ADHD diagnosis and prescribed MPH between 2000 and 2010 were compared with 68 096 without an MPH prescription, matched on age, gender and year of first ADHD diagnosis. All participants were followed to death, migration, withdrawal from the National Health Insurance programme or 31 December 2013. MPH prescriptions were measured on a yearly basis during the study period, and the association between MPH use and mortality was analysed using a repeated-measures time-dependent Cox regression model. The outcome measures included all-cause, unnatural-cause (including suicide, accident and homicide) and natural-cause mortality, obtained from linkage to the National Mortality Register in Taiwan. RESULTS: The MPH group had lower unadjusted all-cause, natural-, unnatural- and accident-cause mortality than the comparison group. After controlling for potential confounders, MPH use was associated with a significantly lower all-cause mortality (adjusted hazard ratio AHR = 0.81, 95% CI 0.67-0.98, P = 0.027), delayed use of MPH was associated with higher mortality (AHR = 1.05, 95% CI 1.01-1.09) and longer MPH use was associated with lower mortality (AHR = 0.83, 95% CI 0.70-0.98). CONCLUSIONS: MPH use is associated with a reduced overall mortality in children with ADHD in this cohort study, but unmeasured confounding cannot be excluded absolutely.

The effects of anxiety on the receipt of treatments for esophageal cancer.

OBJECTIVE: This study aimed to evaluate the association between anxiety and receipt of treatments for esophageal cancer. METHODS: We used a population-based cohort to obtain information of patients with esophageal cancer. Baseline diagnoses of depression or anxiety were identified. Competing risk analyses were used to estimate hazard ratios for risk factors affecting the receipt of anticancer therapies. Subanalysis for the association of anxiety and anticancer therapy stratified by covariates were also performed. RESULTS: Ten thousand five hundred thirty-seven patients with esophageal cancer were identified. Seven hundred thirty-two patients (6.9%) had anxiety disorder before the diagnosis of esophageal cancer. Competing risk model showed that having anxiety disorder was positively associated with the receipt of anticancer treatments (hazard ratio 1.12, 95% CI 1.03-1.22, P = .011), while having depression did not affect patients' status of receiving treatments (hazard ratio 1.05, 95% CI 0.93-1.19, P = .462). Besides, older age, female gender, lower income, and having comorbidities of chronic renal failure and liver cirrhosis were associated with a decreased possibility of receiving anticancer therapy. CONCLUSIONS: Our results indicate that esophageal cancer patient with anxiety disorder has higher possibility to receive anticancer therapy than patients without anxiety disorder.

Increased risk of developing psychiatric disorders in children with attention deficit and hyperactivity disorder (ADHD) receiving sensory integration therapy: a population-based cohort study.

Parents of children with attention deficit hyperactivity disorder (ADHD) have been found to prefer sensory integration (SI) training rather than guideline-recommended ADHD treatment. This study investigated whether SI intervention for children with ADHD was associated with a reduced risk of subsequent mental disorders. From children < 8-years-old newly diagnosed with ADHD in a nationwide population-based dataset, we established a SI cohort and a non-SI cohort (N =  1945) matched by propensity score. Incidence and hazard ratios of subsequent psychiatric disorders were compared after a maximum follow-up of 9 years. The incidence of psychiatric disorders was 1.4-fold greater in the SI cohort, with an adjusted hazard ratio of 1.41 (95% confidence interval 1.20-1.67), comparing to the non-SI cohort. Risks were elevated for emotional disturbances, conduct disorders, and adjustment disorders independent of age, gender, or comorbidity. Among children with only psychosocial intervention, the incidence of psychiatric disorders was 3.5-fold greater in the SI cohort than in the non-SI cohort. To our knowledge, this is the first study to report an increased risk of developing psychiatric disorders for children with ADHD who received SI compared to those who did not. Potential adverse effects of SI for ADHD children should be carefully examined and discussed before practice.

The Psychometric Properties in the Chinese Version of the Reasons for Living Inventory and the Relationship with Suicidal Behaviors Among Psychiatric Patients in Taiwan.

This study examines the reliability, factor structure, convergent, and construct validities of the Mandarin Chinese version of the Reasons For Living Inventory (RFL) among Taiwanese psychiatric patients. Demographical characteristics of patients who hold these adaptive cognitions and differences on the level of endorsement between suicidal and non-suicidal individuals were also investigated. All adult patients that had visited the psychiatric ambulatory clinic or had been admitted to the psychiatric ward in a general hospital in Taiwan over a 3-month period were consecutively invited to complete an inventory that included background information, the Mandarin Chinese versions of the RFL, the Suicidal Behaviors Questionnaire-Revised (SBQ-R), and the Beck Hopeless Scale (BHS). Of the 254 respondents aged 19 to 65 years, 47.2% had suicidal ideations or attempts within the past year. The original six-factor structure of the American version was confirmed to be acceptable. The Cronbach α was 0.964.Total scores on RFL were inversely and significantly correlated with that from BHS. Multivariate analysis with demographic data and items from SBQ-R revealed that higher scores on the RFL have been associated with married, have children or religious beliefs, fewer past and current suicidal ideations and attempts, fewer histories of suicidal threats, and a less self-reported likelihood of future suicide in our sample. The Mandarin version of the RFL inventory showed acceptable psychometric properties and could distinguish suicidal patients from non-suicidal ones.

Risk Factors for Sudden Cardiac Death Among Patients with Alcohol Dependence: A Nested Case-Control Study.

BACKGROUND: Excessive alcohol consumption causes a broad range of health problems, including premature mortality and sudden cardiac death (SCD). We identified potential clinical characteristics and laboratory indices associated with SCD among patients with alcohol dependence. METHODS: Patients with alcohol dependence (n = 2,793) admitted to a psychiatric center in northern Taiwan between 1985 and 2008 were linked with a national mortality database for causes of death. Of the 2,793 patients in the cohort, 67 cases died of SCD. The standardized mortality ratio (SMR) of SCD relative to the general population was calculated. Based on a nested case-control design, we selected a set of sex-, age-, and year-of-admission-matched two control subjects for each case derived from the cohort. We collated the clinical information through a standardized review of patients' medical records. Conditional logistic regressions were then conducted to explore potential exposures associated with SCD. RESULTS: The sample had substantially higher SCD mortality (SMR 12.8) compared to the general population. After adjustments in the multivariate analyses for the clinical profiles at the index (earliest) admission, both abnormal electrocardiography (ECG) (adjusted risk ratio = 16.97, 95% confidence interval (CI) 1.60 to 179.58, p = 0.019) and elevated aspartate aminotransferase levels (adjusted risk ratio = 1.01, 95% CI 1.00 to 1.02, p = 0.046) were significantly associated with SCD. CONCLUSIONS: This study raises the question of whether intensive follow-up of patients with elevated AST and abnormal ECG findings should be evaluated as a strategy to prevent SCD in patients with alcohol dependence.

Validation of the Chinese SAD PERSONS Scale to predict repeated self-harm in emergency attendees in Taiwan.

BACKGROUND: Past and repeated self-harm are long-term risks to completed suicide. A brief rating scale to assess repetition risk of self-harm is important for high-risk identification and early interventions in suicide prevention. The study aimed to examine the validity of the Chinese SAD PERSONS Scale (CSPS) and to evaluate its feasibility in clinical settings. METHODS: One hundred and forty-seven patients with self-harm were recruited from the Emergency Department and assessed at baseline and the sixth month. The controls, 284 people without self-harm from the Family Medicine Department in the same hospital were recruited and assessed concurrently. The psychometric properties of the CSPS were examined using baseline and follow-up measurements that assessed a variety of suicide risk factors. Clinical feasibility and applicability of the CSPS were further evaluated by a group of general nurses who used case vignette approach in CSPS risk assessment in clinical settings. An open-ended question inquiring their opinions of scale adaptation to hospital inpatient assessment for suicide risks were also analyzed using content analysis. RESULTS: The CSPS was significantly correlated with other scales measuring depression, hopelessness and suicide ideation. A cut-off point of the scale was at 4/5 in predicting 6-month self-harm repetition with the sensitivity and specificity being 65.4% and 58.1%, respectively. Based on the areas under the Receiver Operating Characteristic curves, the predictive validity of the scale showed a better performance than the other scales. Fifty-four nurses, evaluating the scale using case vignette found it a useful tool to raise the awareness of suicide risk and a considerable tool to be adopted into nursing care. CONCLUSIONS: The Chinese SAD PERSONS Scale is a brief instrument with acceptable psychometric properties for self-harm prediction. However, cautions should be paid to level of therapeutic relationships during assessment, staff workload and adequate training for wider clinical applications.

An exploratory analysis on the association between suicidal ideation and the microbiome in patients with or without major depressive disorder.

BACKGROUND: Scarce research has investigated associations between suicidal ideation and the gut microbiota. We aimed to explore variations in the gut microbiome associated with suicidal ideation and major depressive disorder (MDD). METHOD: A case-control study compared abundances of fecal microbiota and biomarkers of gut permeability among patients with MDD, with or without suicidal ideation, and healthy volunteers without depression. Information on demographic variables and assessments of suicidal ideation (Beck Suicidal Ideation Scale), depression (Hamilton Depression Scale, Patient Health Questionnaire, Hospital Anxiety and Depression Scale- Depression), as well as anxiety (Hospital Anxiety and Depression Scale- Anxiety), were obtained. Univariate and multivariate regression model was performed to explore the possible predictors of suicidal ideation. RESULTS: Among the 140 participants, significant differences in Beta diversity were found between MDD patients with (n = 43) or without suicidal ideation (n = 34), and healthy volunteers (n = 42) (all p < 0.001). The strain of g-Phascolarctobacterium was found to have significant positive associations with scores of BSSI and BSSI Part 1 (suicidal ideation), particularly in MDD patients with suicidal ideation, after controlling for demographic and mood covariates. Mediation analyses revealed that g-Phascolarctobacterium may be a partial mediator between depression and suicidal ideation; however, it is also possible that the association between g-Phascolarctobacterium and suicidal ideation was partially mediated by the level of depression. CONCLUSION: We found different compositions, diversities, and possible mediating of the gut microbiome associated with suicidal ideations. Potential mechanisms need further investigation to establish whether this reflects a biological process that might be the focus for intervention development. SYNOPSIS: Our objective was to investigate whether the diversities and abundances of the gut microbiome varied in people with or without suicidal ideation and with or without MDD after considering possible demographic and mood confounders.

Trends of drug expenditure in Taiwan National Health Insurance before and during COVID-19 pandemic.

Background: The Taiwanese government adopted the National Health Insurance (NHI) system in March 1995. This study aimed to understand the difference in medication costs before (year 2019) and during the COVID-19 pandemic (2020-2021) among different hospitals for treating their patients. Methods: The NHI claims database consisting of claims of prescription drugs for inpatients (IPD) and outpatients (OPD) in Taiwan was used to determine drug expenditure in different hospitals, particularly the top 10 prescription Anatomical Therapeutic Chemical (ATC) categories. Results: In medical centers, L01X (other antineoplastic agents) showed the highest drug expenditure, followed by L04A (immunosuppressants) and J05A (direct-acting antivirals). The drug expenditure pattern in regional hospitals was similar to that in medical centers, with L01X (other antineoplastic agents) showing the highest drug expenditure. L01X (other antineoplastic agents) also showed the highest drug expenditure in district hospitals, followed by N05A (antipsychotics) and A10B (blood glucose-lowering drugs, excluding insulin). In clinics, A10B (blood glucose-lowering drugs, excluding insulin) showed the highest drug expenditure. The total medication costs in 2021 were lower or similar to those in 2019. The use of systemic use anti-infectives decreased over time in OPDs among all hospita1 levels but increased in IPDs in medical centers and district hospitals. Furthermore, our analysis revealed that the trend in drug expenditure closely mirrored the trend in drug prescription volume for the highest annual sum cost item among the top 10 drug subgroups across different hospital levels. Conclusion: Our analysis found that annual drug expenditures in 2021 were lower or similar to those in 2019, suggesting that the COVID-19 pandemic has contributed to this reduction in drug expenditure.

Stool microbiota analysis for abundance of genus Klebsiella among adults and children in endemic area for community Klebsiella pneumoniae infection.

BACKGROUND: Invasive Klebsiella pneumoniae syndrome is a significant endemic disease in Taiwan. Intestinal colonization of virulent clones that cause this phenomenon has been demonstrated in asymptomatic adults. Comparisons of healthy adults and children with stool K. pneumoniae colonization have rarely been reported. We aimed to evaluate the frequency and abundance of K. pneumoniae in the stool of adults and children by stool microbiota analysis. METHODS: Healthy volunteers and their children without antibiotic exposure within 3 months were recruited in a Taiwanese medical center. Stool samples were sent for gut microbiota analysis, using amplification of V3-V4 hypervariable regions of 16sRNA followed by high-throughput sequence. Rectal/stool swabs were sent for K. pneumoniae culture and identification by matrix-assisted laser desorption ionization-time-of-flight mass spectrometry (MALDI-TOF MS). RESULTS: Fifty-five adults with a mean age of 46.9 years (range, 23.1-72.1 years) and 20 children with a mean age of 2.3 years (range, 0.9-5.8) were enrolled, and 29 adults and 6 children had positive K. pneumoniae swabs. Children had lower microbiota diversity than adults, including higher abundance of phylum Actinobacteria and Proteobacteria, and lower Bacteriodetes. For genus comparison, higher abundance of Escherichia, Streptococcus, Enterococcus and Bifidobacterium were found in children, but the composite abundance of Klebsiella in adults (median: 0.0156, range: 0-0.031) and in children (median: 0.0067, range: 0-0.043) were similar. Klebsiella abundance was significantly higher in participants with positive swabs (p < 0.0001). Klebsiella-positive swabs were strongly negatively correlated with Enterobacter spp. (p < 0.0001), but no known demographic factors correlated with Klebsiella-positive swabs. CONCLUSION: Klebsiella species are present in young children, and the abundance is similar in adults and children. Positive swabs correlate strongly with higher abundance in microbiota analysis.

Lacticaseibacillus paracasei PS23 increases ghrelin levels and modulates microbiota composition: a post-hoc analysis of a randomized controlled study.

Muscle damage can occur due to excessive, high-intensity, or inappropriate exercise. It is crucial for athletes and sports enthusiasts to have access to ways that expedite their recovery and alleviate discomfort. Our previous clinical trial demonstrated the anti-inflammatory and muscle damage-ameliorating properties of Lacticaseibacillus paracasei PS23 (PS23), prompting us to further explore the role of this probiotic in muscle damage recovery. This post-hoc analysis of a randomized controlled study investigated potential mediators between the intake of PS23 and the prevention of strength loss after muscle damage. We recruited 105 students from a sports university who had participated in the previously published clinical trial. These participants were randomly allocated to three groups, receiving capsuled live PS23 (L-PS23), heat-treated PS23 (HT-PS23), or a placebo over a period of six weeks. Baseline and endpoint measurements were taken for the levels of circulating ghrelin and other blood markers, stress, mood, quality of life, and the fecal microbiota. A significant increase in ghrelin levels was recorded in the L-PS23 group compared to the other groups. Additionally, both L-PS23 and HT-PS23 interventions led to positive shifts in the gut microbiota composition, particularly in elevated Lacticaseibacillus, Blautia, and Lactobacillus populations. The abundance of these bacteria was positively correlated with exercise performance and inversely correlated with inflammatory markers. In conclusion, dietary supplementation with PS23 may enhance exercise performance and influence muscle damage by increasing ghrelin levels and modulating the gut microbiota composition. Further clarification of the possible mechanisms and clinical implications is required.

Psychiatric disorders in term-born children with marginally low birth weight: a population-based study.

BACKGROUND: Marginally low birth weight (MLBW) is defined as a birth weight of 2000 ~ 2499 g. Inconsistent findings have been reported on whether children with low birth weight had higher rates of neurological, attention, or cognitive symptoms. No studies have explored the occurrence of clinically diagnosed psychiatric disorders in term- born MLBW infants. We aimed to investigate the risk of subsequent psychiatric disorders in term-born children with MLBW. METHODS: This is a nationwide retrospective cohort study, by analysing the data from Taiwan's National Health Insurance Research Database from 2008 to 2018. The study population includes propensity-score-matched term-born infants with MLBW and those without MLBW (birth weight ≥ 2500 g). Cox proportional hazard analysis was used after adjustment for potential demographic and perinatal comorbidity confounders. Incidence rates and hazard ratios (HR) of 11 psychiatric clinical diagnoses were evaluated. RESULTS: A total of 53,276 term-born MLBW infants and 1,323,930 term-born infants without MLBW were included in the study. After propensity score matching for demographic variables and perinatal comorbidities, we determined that the term-born MLBW infants (n = 50,060) were more likely to have attention deficit and hyperactivity disorder (HR = 1.26, 95% confidence interval (CI) [1.20, 1.33]), autism spectrum disorder (HR = 1.26, 95% CI [1.14, 1.40]), conduct disorder (HR = 1.25, 95% CI [1.03, 1.51]), emotional disturbance (HR: = 1.13, 95% CI [1.02, 1.26]), or specific developmental delays (HR = 1.38, 95% CI [1.33, 1.43]) than term-born infants without MLBW (n = 50,060). CONCLUSION: MLBW was significantly associated with the risk of subsequent psychiatric disorder development among term-born infants. The study findings demonstrate that further attention to mental health and neurodevelopment issues may be necessary in term-born children with MLBW. However, possibilities of misclassification in exposures or outcomes, and risks of residual and unmeasured confounding should be concerned when interpreting our data.

Associations of asthma and psychiatric comorbidities on suicide mortality among community adolescents: A 20-year cohort study.

BACKGROUND: The role of psychiatric comorbidity as a confounder between asthma and subsequent suicide mortality in adolescents remained unclarified. METHODS: This study used a 20-year community-based cohort in Taiwan. Adolescents aged 11 to 16 from 123 schools were classified into three subgroups: current asthma (symptoms present in the past year), previous asthma (history of asthma but no symptoms in the past year), and no asthma. The mortality and medical care utilizations until the end of follow-up in 2015 were obtained. Cox proportional hazard and competing risk models were performed. Different adjustment models that included covariates of demographic status, allergy, cigarette smoking, psychiatric diagnoses, alcohol or substance misuse, and attention deficit and hyperactivity disorders were compared. RESULTS: During the follow-up, 285 out of 153,526 participants died from suicide. The crude hazard ratio for suicide was 1.95 (95 % CI=1.46∼2.60) in the current asthma subgroup and 2.01 (1.36∼2.97) in the previous asthma subgroup. The adjusted hazard ratios (aHR) attenuated to 1.67 (1.25∼2.24) and 1.72 (1.16∼2.54) respectively after further adjustment for all mental disorders, ADHD, substance, and alcohol use disorders. CONCLUSIONS: Our adjustment analyses stratified by different models highlight evidence of asthma as an independent risk factor that predicts suicide among adolescents. Depression and mental disorders were potential confounders and identifications of asthma and psychiatric disorders might help decrease suicide risk.

Excess Mortality in Individuals with Autism Spectrum Disorder: A Population-Based Cohort Study.

Purpose: Autism spectrum disorder (ASD) may be associated with increased mortality, but relevant findings have been inconsistent. The modifying effects of gender and intellectual disability on excess mortality in individuals with ASD are underexplored. Patients and Methods: Using Taiwan's National Health Insurance Research Database and the National Death Registry, this population-based cohort study selected the data of 75,946 patients with ASD (ASD cohort) and 75,946 age group-, gender-, and income-matched (1:1) patients without ASD (non-ASD cohort). Cox proportional hazards models were used to compare mortality rates between the cohorts, and stratified analyses were used to evaluate the influence of gender and intellectual disability on mortality risk. Results: The ASD cohort had higher mortality rates for all causes of death than did the non-ASD cohort (adjusted hazard ratio 1.64, 95% confidence interval 1.54-1.75). Comorbid intellectual disability was associated with an increased risk of mortality, and this association was stronger in female patients than in male patients. Moreover, when focusing on deaths from natural causes, we found a significantly higher odds ratio for mortality in the ASD population with ID compared to those without ID. Conclusion: ASD is associated with increased mortality, especially among female individuals and those with intellectual disability.

Diagnostic procedures, revascularization, and inpatient mortality after acute myocardial infarction in patients with schizophrenia and bipolar disorder.

OBJECTIVE: To investigate inpatient mortality and the use of invasive diagnostic and revascularization procedures after acute myocardial infarction (AMI) in people with schizophrenia and bipolar disorder. METHODS: A case-control study was nested within the first AMI episodes between 1996 and 2007 using nationwide data. Participants with schizophrenia or bipolar disorder were compared with a random sample of all other adults without severe mental illness. Inpatient mortality and receipt of cardiac catheterization, coronary arteriography, percutaneous transluminal coronary angioplasty, and coronary artery bypass graft were compared in logistic regression models after adjusting for demographic and health status, hospital type, and AMI complications. RESULTS: A total of 3361 adult patients who had incident AMI between 1996 and 2007 were identified. Patients with schizophrenia and bipolar disorder (n = 834; 24.8%) had a significantly decreased likelihood of catheterization (12.2% and 14.0%, respectively) and revascularization (9.0% and 12.8%, respectively) during the index AMI episode compared with controls (27.9% of whom received catheterization and 23.9% of whom received revascularizations). Inpatient mortality remained 2.68 times the rate in patients with schizophrenia (95% confidence interval = 1.73-4.15; p < .001) compared with controls after adjusting for intervention receipt among other covariates, but mortality was not significantly raised in patients with bipolar disorder. CONCLUSIONS: In a large national sample and in the context of a comprehensive free health service, patients with schizophrenia and bipolar disorder were substantially disadvantaged, being half as likely to receive catheterization or revascularization procedures after AMI. Further research is required to clarify the reasons for this.

Effects of short-term interventions to reduce mental health-related stigma in university or college students: a systematic review.

Although there are many interventions to reduce mental health-related stigma in university or college students, their overall effect is unknown. This article systematically reviews intervention studies and aims to identify the effective approaches. We searched 11 bibliographic databases, Google, Web sites of relevant associations, and reference lists and contacted specialists. A total of 35 studies (N = 4257) of a wide range of interventions met the inclusion criteria. Social contact or video-based social contact interventions seemed to be the most effective in improving attitudes and reducing desire for social distance. Evidence from one study suggests that a lecture that provided treatment information may enhance students' attitudes toward the use of services. However, methodological weaknesses in many studies were also found. There was a lack of evidence for interventions in medical students, for long-term effects of interventions, or for having a positive impact on actual behaviors. Further research having more rigorous methods is needed to confirm this.
