Anxiety disorders are among the most common mental disorders worldwide, and most previous studies have focused solely on alcohol drinking or tobacco smoking as risk factors for anxiety.

This study investigated the associations of alcohol drinking and tobacco smoking with anxiety.

The data of 30 836 individuals in the Taiwan Biobank were retrieved and analysed in our study. To investigate the associations of tobacco and alcohol use with anxiety, we analysed Patient Health Questionnaire 4 (specifically scores for the first two questions assessing generalised anxiety disorder) results of the included participants and data on their tobacco and alcohol use, and other covariates.

Participants who used only tobacco and those using both tobacco and alcohol were more likely to experience anxiety than were those who did not use tobacco or alcohol. Among men, the use of alcohol and/or tobacco was associated with a significantly higher risk of anxiety. Among women, the use of both alcohol and tobacco was associated with a significantly higher risk of anxiety. Older age was associated with a lower risk of anxiety.

Tobacco and alcohol use significantly influence the risk of anxiety, particularly in men, and older age also influences this risk. The associations of anxiety with tobacco and alcohol use in women may change because of the increasing prevalence of their use among women in Taiwan in recent years.

Increasing evidence has established a strong association between social anxiety disorder and suicidal behaviours, including suicidal ideation and suicide attempts. However, the association between social anxiety disorder and suicide mortality remains unclear.

This study analysed data from 15,776 patients with social anxiety disorder, extracted from a nationwide Taiwanese cohort between 2003 and 2017. Two unexposed groups without social anxiety disorder, matched by birth year and sex in 1:4 and 1:10 ratios, respectively, were used for comparison. Suicide deaths during the same period were examined. Psychiatric comorbidities commonly associated with social anxiety disorder, including schizophrenia, bipolar disorder, major depression, alcohol use disorder (AUD), substance use disorder (SUD), obsessive-compulsive disorder, autism, and attention deficit hyperactivity disorder, were identified.

Time-dependent Cox regression models, adjusted for demographic factors and psychiatric comorbidities, revealed that individuals with social anxiety disorder had an increased risk of suicide (hazard ratio: 3.49 in the 1:4 matched analysis and 2.84 in the 1:10 matched analysis) compared with those without the disorder. Comorbidities such as schizophrenia, bipolar disorder, major depression, AUD, and SUD further increased the risk of suicide in patients with social anxiety disorder.

Social anxiety disorder is an independent risk factor for suicide death. Additional psychiatric comorbidities, including schizophrenia, major affective disorders, and AUD, further increased social anxiety disorder-related suicide risk. Therefore, mental health officers and clinicians should develop targeted suicide prevention strategies for individuals with social anxiety disorder.

To construct an evidence-based practice programme for the nutrition management of older adults in nursing homes. The programme will provide a basis for improving or solving the nutrition management problems of older adults in nursing homes.

The study is based on guideline evidence and Delphi method. The evidence was comprehensively searched, assessed and summarized, and the best evidence and a preliminary programme for nutrition management of older adults in nursing homes were aggregated. Then, the Delphi method was used to assess the applicability of the preliminary programme and the obstacle factors to modify, supplement and improve the nutrition management programme.

Baseline survey data were collected from three nursing homes in Ningxia, China, and guideline evidence was obtained through systematic searches of the Cochrane Library, PubMed and other scientific databases, as well as relevant official websites.

A total of 350 older adults residing nursing homes and 160 nurses participated in the baseline survey. To ensure the programme’s applicability and identify potential implementation obstacles, fifteen experts from local grade A hospitals, nursing homes and community health centres were consulted for review.

A fourteen-item, fifty-six-best-evidence nutrition management programme for older adults in nursing homes was developed based on five guideline evidences and baseline survey findings.

This is a systematic and comprehensive nutritional management programme for older adults in nursing homes based on guideline evidence, which can provide a standardised basis for the implementation of scientific nutritional management in nursing homes in Ningxia. Managers should promote the translation of evidence into practice in accordance with the specific circumstances of individual nursing homes.

Inconsistent results regarding the risk of relapse and better subjective outcomes of previous antipsychotic dose reduction trials in patients with remitted psychosis have not been verified using therapeutic drug monitoring (TDM). This study examined plasma drug concentrations of a dose-tapering trial which exhibited the potential of successful maintenance under lower antipsychotic dosages.

A 2-year open-label randomized prospective trial recruited remitted patients to undergo guided antipsychotic tapering. Blood samples were collected at baseline, annually, and after each dose reduction. Plasma aripiprazole/dehydroaripiprazole concentrations were determined using LC–MS/MS. The relationship between the dose and serum drug levels was examined using Spearman's correlation. Divided at 120 ng/mL, relapse rate, global function, quality of life, and psychopathology were compared between high- and low- drug level groups.

A total of 126 blood samples were collected, after excluding13 samples due of non-adherence. The correlation coefficients between dosage and drug level were 0.853 (aripiprazole) and 0.864 (dehydroaripiprazole), and the dose and concentration plots were parallel along the tapering trajectories, except patients with non-adherence. The concentration-to-dose ratio of aripiprazole in this cohort, 17.79 ± 7.23 ng/mL/mg, was higher than that in Caucasian populations. No significant differences were observed in the clinical outcomes between the high- and low-level groups. Remarkably, 12 of 15 patients maintained remission at plasma aripiprazole concentrations of <120 ng/mL.

The lower-than-expected doses reached in our antipsychotic tapering trial were substantiated to provide adequate prophylactic effects by TDM results in a subset of patients treated with aripiprazole, even considering the differences in pharmacogenomics between ethnicities.

Adolescence is an important period for the development of the possible self. It is also a time when depression is prevalent. The cognitive theory of depression proposes that a negative view of the future is a key feature of depression. Targeting these negative thoughts about the future during cognitive behavioural therapy may be helpful in depression. However, little is known about how adolescents envisage their future (i.e. possible) self, or if the content is associated with affect. The aim of this quantitative study is to describe how adolescents describe their ‘possible self’ and examine the relationship between the valence of the possible self and depression in adolescents.

Adolescents (n = 584) aged 13–18 years were recruited via opportunity sampling via their schools and completed measures of depression symptoms (the Mood and Feelings Questionnaire) and the ‘possible self’ (a variant of the ‘I Will Be’ task). Possible selves were coded for content and valence.

Despite depression severity, the most common possible selves generated by adolescents were positive and described interpersonal roles. The valence of the possible self was associated with depression severity but only accounted for 3.4% of the variance in severity.

The results support the cognitive model of depression. However, adolescents with elevated symptoms of depression were able to generate positive, possible selves and therefore may remain somewhat ‘hopeful’ about their future despite clinically significant depression symptoms. Future-oriented treatment approaches such as cognitive behavioural therapy that focus on changing unhelpful negative future thinking may not be appropriate for this population.

Many studies supported that children with autism spectrum disorder (ASD) have worse executive functions (EFs) when compared to typically developmental (TD) children in many domains, such as planning, flexibility, inhibition, and self-monitoring. The current study aims to use an adapted version of the computerized tower test to investigate the EFs of children with ASD. Furthermore, the researcher also assessed children's EFs-related behaviors in their schools using a teacher-filled behavior rating inventory of executive function, 2nd edition (BRIEF-2).

61 Children aged 7 to 12 years old (M = 9.23) were included in the current study. 29 of them were in the ASD group, and 31 of them were in the TD group. All participants conducted an adapted computerized tower test. All participants' teachers completed BRIEF-2 to investigate their EFs-related behaviors in their schools.

The results indicated that there were no significant differences in the tower test between the ASD group and TD group in all indexes. Therefore, it implied that the current indexes might not be sensitive enough to distinguish whether a child has ASD or not. In addition, we further investigate the correlations between the tower test and the teacher-filled BRIEF-2. We found the different patterns in the two groups. In the ASD group, we found that the task-monitor index was positively correlated with total-number-of-rule-violations, total-complete-time, and total-rule-violations-per-item-ratio. The task-monitor index was negatively correlated with total-achievement-score, implying that poorer ability to monitor tasks leads to a longer completion time, more rule violations, and a lower total achievement score. Moreover, we also found a high correlation between the organization-of-materials in BRIEF-2 and total-complete-time in the tower test, suggesting the long problem-solving time in ASD groups is highly related to the disability of keeping working space ordered. In addition, we found that the shift index is positively correlated with total-complete-time and total-rule-violations-per-item-ratio. Hence, it indicates that those with poor flexibility in solving problems tend to need more time to complete tasks and violate more rules in ASD groups. In the TD group, we only found the correlation effects were significant between inhibition and self-monitor in the BRIEF-2 and the total-rule-violations-per-item-ratio in the tower test. It suggested that individuals with behavioral regulation problems, such as impulse control and monitoring problems are more likely to make rule violations. The result indicated that behavioral regulations play a more significant role in the TD group. In contrast, cognitive and emotional regulations are more critical in ASD children.

Our findings found no significant difference in the computerized tower test between children with and without ASD, suggesting that the current indexed might not be sensitive enough to differentiate children with or without ASD. However, the results of the correlation between the tower test and teacher-filled BRIEF-2 showed that different patterns might be the cause of the EF performances between the two groups, indicating that there might be a different domain of EFs the children used in the tower test between two groups.

Therefore, further research could focus on developing new indexes in the Tower test and finding the EF mechanism of ASD children with different approaches.

Somatic symptom disorders (SSD) and functional somatic syndromes (FSS) are often regarded as similar diagnostic constructs; however, whether they exhibit similar clinical outcomes, medical costs, and medication usage patterns has not been examined in nationwide data. Therefore, this study focused on analyzing SSD and four types of FSS (fibromyalgia, chronic fatigue syndrome, irritable bowel syndrome, functional dyspepsia).

This population-based matched cohort study utilized Taiwan's National Health Insurance (NHI) claims database to investigate the impact of SSD/FSS. The study included 2 615 477 newly diagnosed patients with SSD/FSS and matched comparisons from the NHI beneficiary registry. Healthcare utilization, mortality, medical expenditure, and medication usage were assessed as outcome measures. Statistical analysis involved Cox regression models for hazard ratios, generalized linear models for comparing differences, and adjustment for covariates.

All SSD/FSS showed significantly higher adjusted hazard ratios for psychiatric hospitalization and all-cause hospitalization compared to the control group. All SSD/FSS exhibited significantly higher adjusted hazard ratios for suicide, and SSD was particularly high. All-cause mortality was significantly higher in all SSD/FSS. Medical costs were significantly higher for all SSD/FSS compared to controls. The usage duration of all psychiatric medications and analgesics was significantly higher in SSD/FSS compared to the control group.

All SSD/FSS shared similar clinical outcomes and medical costs. The high hazard ratio for suicide in SSD deserves clinical attention.

Patients with remitted psychosis wish to reduce antipsychotic doses yet facing increased risks of relapse. Examining dose-tapering processes may provide insights to re-evaluate the risk-to-benefit balance. We aimed to depict and subgroup tapering trajectories, and explore factors associated with different dose-reduction patterns.

A 2-year open-label randomized prospective comparative trial from August 2017 to September 2022 in Taiwan. Patients with a history of schizophrenia-related psychotic disorders under stable medications and symptoms were eligible, randomizing a proportion to conduct guided dose reduction. We depicted the trajectories of individual patients and named subgroups based on dose-tapering patterns. Predictors of baseline characteristics for designated subgroups were examined by logistic regression analysis; changes in outcomes were compared by paired t-test.

Fifty-one patients undergoing guided dose reduction, 18 (35.3%) reduced 4 steps consecutively (sequential reducers, SR), 14 (27.5%) reduced 1 to 3 steps (modest reducers, MR), 3 (5.9%) re-escalated to previous level (alert reducers, AR), 7 (13.7%) returned to baseline level (baseline returners, BR), 6 (11.7%) relapsed (failed reducers, FR) and 3 (5.9%) withdrew without relapse (early exits, EE). Patients with a history of relapse assumed a conservative dose-tapering pace; only the SR subgroup exhibited significant improvements in functioning and quality of life while failing to identify variables for predicting who would become SR or FR.

Guided dose reduction comprises dynamic processes with differences between individual trajectories. The proposed naming of dose-tapering patterns/subgroups provides a framework depicting patients undergoing dose-tapering. Longer-term observation and more flexible tapering approaches are anticipated to reveal favorable outcomes.

Individuals who self-harm have increased suicide rates. Brief interventions are associated with reduced repeated suicide attempts. However, very few previous studies investigated the acceptability of brief interventions before implementing new trials.

We aimed to explore the perceptions of individuals who self-harm toward a brief intervention, the Chinese version of the volitional help sheet (VHS-C), which encourages people to link a critical situation with an appropriate response.

Fourteen participants who presented to hospitals with self-harm were interviewed about their perspectives regarding the acceptability of the paper- and web-based VHS-C. Data were analysed with the framework method.

The participants could understand the intended goal of the VHS-C by reading the written instructions, but indicated that having verbal instructions would also help. They shared the reasons why they felt the VHS-C was helpful (e.g. relatable contents, useful coping strategies and appropriate instructions that made them feel understood) or unhelpful (e.g., being not specific enough, not useful during the crisis and triggering negative emotional responses). Some indicated that the VHS-C might not be applicable to people experiencing ongoing distress in emergency departments. Most participants preferred the web-based to the paper-based VHS-C, and suggested that the format and frequency of follow-up reminders could leave the patient to decide.

The contents of the VHS-C were acceptable for people who presented to hospitals with self-harm. The VHS-C may be more helpful before individuals encounter suicidal thoughts than when they have an ongoing crisis.
