A network model of depressive and anxiety symptoms: a statistical evaluation.

BACKGROUND: Although network analysis studies of psychiatric syndromes have increased in recent years, most have emphasized centrality symptoms and robust edges. Broadening the focus to include bridge symptoms within a systematic review could help to elucidate symptoms having the strongest links in network models of psychiatric syndromes. We conducted this systematic review and statistical evaluation of network analyses on depressive and anxiety symptoms to identify the most central symptoms and bridge symptoms, as well as the most robust edge indices of networks. METHODS: A systematic literature search was performed in PubMed, PsycINFO, Web of Science, and EMBASE databases from their inception to May 25, 2022. To determine the most influential symptoms and connections, we analyzed centrality and bridge centrality rankings and aggregated the most robust symptom connections into a summary network. After determining the most central symptoms and bridge symptoms across network models, heterogeneity across studies was examined using linear logistic regression. RESULTS: Thirty-three studies with 78,721 participants were included in this systematic review. Seventeen studies with 23 cross-sectional networks based on the Patient Health Questionnaire (PHQ) and Generalized Anxiety Disorder (GAD-7) assessments of clinical and community samples were examined using centrality scores. Twelve cross-sectional networks based on the PHQ and GAD-7 assessments were examined using bridge centrality scores. We found substantial variability between study samples and network features. 'Sad mood', 'Uncontrollable worry', and 'Worrying too much' were the most central symptoms, while 'Sad mood', 'Restlessness', and 'Motor disturbance' were the most frequent bridge centrality symptoms. In addition, the connection between 'Sleep' and 'Fatigue' was the most frequent edge for the depressive and anxiety symptoms network model. CONCLUSION: Central symptoms, bridge symptoms and robust edges identified in this systematic review can be viewed as potential intervention targets. We also identified gaps in the literature and future directions for network analysis of comorbid depression and anxiety.

Utilizing plasma drug levels and genetic testing to achieve optimal treatment response in a patient with treatment-resistant schizoaffective disorder.

We report the case of a Chinese male with schizoaffective disorder, an active smoker and a nonresponder to clozapine (600 mg daily). Therapeutic clozapine monitoring was analyzed, revealing a low concentration-dose ratio. A pharmacogenetic test showed that the patient had the CYP1A2*1F/*1F genotype, indicating an ultra-rapid clozapine metabolizer. In combination with fluvoxamine, a CYP1A2 enzyme inhibitor, clozapine plasma concentrations approached the reference range and achieved clinical improvement. This case demonstrates how pharmacogenetics can help understand the value of therapeutic drug monitoring to enhance the treatment of refractory schizoaffective disorder.

Exploring the interplay of psychiatric symptoms, antipsychotic medications, side effects, employment status, and quality of life in Chronic Schizophrenia.

BACKGROUND: Many factors contribute to quality of life (QoL) in patients with schizophrenia, yet limited research examined these factors in patients in China. This cross-sectional study explores subjective QoL and its associated factors in patients. METHODS: The QoL was assessed using the Schizophrenia Quality of Life Scale (SQLS). Clinical symptoms were evaluated using the Brief Psychiatric Rating Scale (BPRS) and seven factors were extracted. Patient Health Questionnaire-9 (PHQ-9), and Generalized Anxiety Disorder Scale (GAD-7) were used to assess depression and anxiety. Cognitive impairment was assessed using the Ascertain Dementia 8 (AD8). The Treatment Emergent Symptom Scale (TESS) and Rating Scale for Extrapyramidal Side Effects (RSESE) were used to evaluate the side effects of medications. RESULTS: We recruited 270 patients (male:142,52.6%, mean age:41.9 ± 9.4 years). Positive correlations were observed between SQLS and its subdomains with the total score of BPRS, PHQ-9, GAD-7, AD8, TESS, and RSESE (all P < 0.005). Patients who were taking activating second-generation antipsychotics (SGAs) had lower scores on total SQLS, Motivation/ Energy domain of SQLS (SQLS-ME) as well as Symptoms/ Side effects domain of SQLS (SQLS-SS) compared to those taking non-activating SGAs (all P < 0.005). Multiple regression analysis showed that depressive/ anxiety symptoms and cognitive impairment had significant negative effects on QoL (P ≤ 0.001), while activating SGAs had a positive effect (P < 0.005). Blunted affect and unemployment were inversely associated with the motivation/energy domain (P < 0.001). CONCLUSION: Our findings emphasize the important role of depression/anxiety symptoms and cognitive impairment in the QoL of patients with chronic schizophrenia. Activating SGAs and employment may improve the QoL of these individuals. TRIAL REGISTRATION: This protocol was registered at chictr.org.cn (Identifier: ChiCTR2100043537).

COVID-19 and Sleep Problems: A Perspective from Bibliometric Analysis.

OBJECTIVES: The Coronavirus Disease 2019 (COVID-19) pandemic and the containment measures for COVID-19 have affected sleep quality in the population. This study explored sleep-related research from a bibliometric perspective to provide an overview of the research outputs in this field. METHODS: Original and review articles were retrieved from the Web of Science Core Collection (WOSCC) database from December 2019 to 7 Aug 2023. R package "bibliometrix" was used to summarize the number of articles of authors, institutions, and countries; count the citations of the articles, and generate a Three-Fields Plot. VOSviewer software was applied to visualize the collaboration network among authors and institutions, and to conduct a co-occurrence analysis of keywords. RESULTS: A total of 4,499 articles on COVID-19 and sleep, and 25,883 articles on non-COVID-19 and sleep were included. Sleep related articles were mainly published by authors from China, the USA, and Italy. For COVID-19 and sleep research, Huazhong University of Science was the most productive institution. The Psychiatry Research was the most influential journal across the different subject categories of this field. "Mental health", "anxiety", and "depression" were the most common keywords, while "sleep quality" and "quality of life" were the likely topic areas in terms of future research directions. CONCLUSIONS: Our findings provide a comprehensive perspective for researchers to understand the wider landscape of both COVID-19 and non-COVID-19 sleep-related research area.

The association between the adverse event reporting system and burnout and job satisfaction of nurses: Workplace violence as a mediator.

AIMS: This study aims to explore the association between the implementation of the adverse event reporting system (AERS), burnout, and job satisfaction among psychiatric nurses, with a focus on examining the mediating effect of workplace violence from patients. BACKGROUND: Many organizational and personal factors contribute to burnout and job satisfaction experienced by nurses. AERS, serving as a key component of organizational-level quality improvement system, impacts the overall workplace wellness of nurses. METHODS: A national sample of 9,744 psychiatric nurses from 41 psychiatric hospitals across 29 provinces in China participated. Burnout was measured by the Maslach Burnout Inventory. Job satisfaction was measured using the Minnesota Satisfaction Questionnaire. Workplace violence was assessed by nurses' experience of verbal and physical violence. Multilevel linear regression analyses were carried out to examine if AERS impacts burnout and job satisfaction and to identify the mediating role of workplace violence. RESULTS: AERS was positively associated with job satisfaction, but negatively with burnout and workplace violence. Workplace violence exhibited a positive association with burnout and a negative association with job satisfaction. Mediation analyses indicated that the associations between AERS, burnout, and job satisfaction were mediated by workplace violence. CONCLUSIONS: The application of AERS is associated with a reduction in workplace violence in hospitals, which contributes to the diminished burnout and heightened job satisfaction among psychiatric nurses. IMPLICATIONS FOR NURSING PRACTICE AND HEALTH POLICY: The study highlights the importance of organizational efforts and mechanisms in promoting nurses' well-being. It is necessary for hospital management to create a safe workplace through the implementation of AERS.

Medication treatment for alcohol use disorder in special populations.

BACKGROUND AND OBJECTIVES: Alcohol use disorder (AUD) is a significant public health concern, with underutilized effective treatments, particularly in special populations. This article summarizes the current evidence and guidelines for treating AUD in special populations. METHODS: This article is a literature review that synthesizes the latest research on AUD treatment for special populations. We screened 242 articles and included 57 in our final review. RESULTS: There are four food and Drug Administration-approved medications for AUD (MAUD): disulfiram, oral naltrexone, extended-release injectable naltrexone (XR-NTX), and acamprosate. Naltrexone and disulfiram have the potential to cause liver toxicity, and acamprosate should be avoided in patients with severe kidney disease. Psychosocial treatments should be considered first-line for pregnant and nursing patients. Naltrexone is contraindicated in patients on opioids, as it may precipitate acute withdrawal. For patients experiencing homelessness, nonabstinent treatment goals may be more practical, and XR-NTX should be considered to improve adherence. Limited evidence suggests medication can improve AUD treatment outcomes in adolescents and young adults. For patients with poor treatment response despite adequate medication adherence, switching to a different medication and augmentation with psychosocial treatments should be considered. DISCUSSION AND CONCLUSIONS: Understanding the unique considerations for special populations with AUD is crucial, and addressing their special needs may improve their treatment outcomes. SCIENTIFIC SIGNIFICANCE: Our study significantly contributes to the existing literature by summarizing crucial information for the treatment of AUD in special populations, highlighting distinct challenges, and emphasizing tailored approaches to improve overall health and well-being.

Efficacy of various surgical approaches in treating hematospermia using transurethral seminal vesiculoscopy.

PURPOSE: To explore the efficacy of different approaches of seminal vesiculoscopy surgery and the predictive factors of good treatment outcome. MATERIALS AND METHODS: A retrospective analysis of 68 patients who underwent seminal vesiculoscopy for hematospermia in our hospital from January 2015 to January 2021. According to different surgical approaches, they were divided into three groups: natural ejaculatory ducts (method A, 45 cases), assisted transurethral resection/incision of ejaculatory ducts (method B, 14 cases), fenestration in prostatic utricle (method C, 9 cases). We analyzed the recurrence rate of the three surgical approaches and the predictive factors of treatment efficacy. RESULTS: The total recurrence rate after the seminal vesiculoscopy for hematospermia in this group was 32.35%. The postoperative recurrence rates of the three methods were 24.44% for method A, 50.00% for method B and 44.44% for method C, and there was no significant difference among the three methods (P > 0.05). The data of five predictors of 45 cases in method A group were included in the Univariate Logistic analysis, the results suggest that whether complicated with seminal tract stones/cysts was an effective predictor (OR 0.250, P = 0.022), which was still an effective predictor in the Multivariate Logistic analysis model (OR 0.244, P = 0.010). CONCLUSIONS: The Transurethral seminal vesiculoscopy technique demonstrates a low postoperative recurrence rate in treating hematospermia. Among the various approaches, the intraoperative use of natural orifices through the ejaculatory duct exhibits the lowest recurrence rate. Additionally, seminal tract stones/cysts effectively predict favorable postoperative outcomes.

Factors Associated With Utilization of Electroconvulsive Therapy During Psychiatric Hospitalization Among Children and Adolescents in China.

PURPOSE: Based on a nationally representative sample in China, we examined the demographic and clinical correlates of utilization of electroconvulsive therapy (ECT) in child and adolescent (C/A) patients younger than 18 years during psychiatric hospitalization. METHODS: As part of a national survey, 41 provincial tertiary psychiatric hospitals in mainland China were selected. Data from 196 C/A patients who were discharged from these psychiatric hospitals from March 19 to 31, 2019, were retrieved and analyzed. RESULTS: (1) The overall rate of ECT among C/A patients during psychiatric hospitalization was 15.6% (n = 30). (2) Between ECT and non-ECT groups, significant differences were found in sex, age, length of stay, Global Assessment of Functioning at admission, treatment outcome, and self-injurious behavior during hospitalization, and the ratio of marked improvement on discharge. (3) Multiple logistic regression analysis revealed that ECT use was independently and positively associated with an older age, male sex, lower Global Assessment of Functioning, and self-injurious behavior during hospitalization. CONCLUSIONS: The frequency of ECT use was relatively frequent in C/A patients during psychiatric hospitalization in our nationally representative sample in China. Developing more specific and operational criteria for the use of ECT for C/A patients is needed to provide guidance for the optimal use of ECT in this patient population.

Neck and shoulder strains under various head flexing positions while standing and sitting with and without back support for male and female smartphone users.

This study recruited 30 young participants (15 men and 15 women) to examine the smartphone usage patterns in three postures (standing, supported sitting, and unsupported sitting) and at five head angle (HA) positions (0°-40°). Cervical erector spinae (CES) and upper trapezius (UTZ) muscle activity, neck flexion (NF), gaze angle (GA), viewing distance (VD), and discomfort scores were collected. Results showed that HA and posture almost affected all responses, while CES muscle activity, NF, and VD differed between sexes. Strain in the neck and shoulder region increased with HA increase. Particularly, when the HA exceeded 20°, the discomfort scores considerably increased. Unsupported sitting should be avoided during smartphone use because of relatively poor responses in all variables. However, both standing and supported sitting have their respective benefits. Sex-related differences were typically observed in the standing position, with women tending to have lower NF but higher CES muscle activity compared with men.Practitioner summary: Although smartphones have become daily necessities, the overall quantitative neck and shoulder strain of using smartphones in different postures is rarely evaluated. We suggest that maintaining the HA within 20° is recommended because of relatively low load on the neck and shoulders. An unsupported sitting should be avoided during smartphone use.

The effects of childhood trauma on personality in unaffected first-degree relatives of patients with major depressive disorder.

ABSTRAC: OBJECTIVES: This study aimed to preliminarily and exploratorily examine the associations between childhood trauma (CT), its subtypes, and personality traits among unaffected first-degree relatives (FDR, children, or siblings) of patients with major depressive disorder (MDD). METHODS: The study sample included three subgroups: MDD patients (N = 85), Patients' FDRs (N = 35), and healthy control individuals (HC, N = 89). The Childhood Trauma Questionnaire (CTQ) was used to assess childhood trauma and the Eysenck Personality Questionnaire was used to assess personality traits. RESULTS: Significant differences were found in a few personality traits (p < 0.05 for extraversion, neuroticism, and psychoticism) among MDD patients, FDR, and HC, and there were no significant differences between HC and FDR. In the FDR group, compared with those without CT, participants with CT scored significantly higher for neuroticism (N) (F = 3.246, p = 0.046). CT was significantly associated with N, psychoticism (P) and Lie (L), and the strongest association was between CT total score and N. Significantly positive correlations were found between N and sexual abuse (SA) (r = 0.344, p = 0.043), emotional neglect (EN) (r = 0.394, p = 0.019), physical neglect (PN) (r = 0.393, p = 0.019), and CTQ total score (r = 0.452, p = 0.006); between P and CTQ total score (r = 0.336, p = 0.049); and significant negative correlations were found between L and EN (r = -0.446, p = 0.007), CTQ total score (r = -0.375, p = 0.027). CONCLUSION: In unaffected FDRs, there were significant associations between childhood trauma and a few personality traits, including neuroticism, psychoticism, and lie, and emotional neglect was significantly associated with neuroticism.

An International Adult Guideline for Making Clozapine Titration Safer by Using Six Ancestry-Based Personalized Dosing Titrations, CRP, and Clozapine Levels.

This international guideline proposes improving clozapine package inserts worldwide by using ancestry-based dosing and titration. Adverse drug reaction (ADR) databases suggest that clozapine is the third most toxic drug in the United States (US), and it produces four times higher worldwide pneumonia mortality than that by agranulocytosis or myocarditis. For trough steady-state clozapine serum concentrations, the therapeutic reference range is narrow, from 350 to 600 ng/mL with the potential for toxicity and ADRs as concentrations increase. Clozapine is mainly metabolized by CYP1A2 (female non-smokers, the lowest dose; male smokers, the highest dose). Poor metabolizer status through phenotypic conversion is associated with co-prescription of inhibitors (including oral contraceptives and valproate), obesity, or inflammation with C-reactive protein (CRP) elevations. The Asian population (Pakistan to Japan) or the Americas' original inhabitants have lower CYP1A2 activity and require lower clozapine doses to reach concentrations of 350 ng/mL. In the US, daily doses of 300-600 mg/day are recommended. Slow personalized titration may prevent early ADRs (including syncope, myocarditis, and pneumonia). This guideline defines six personalized titration schedules for inpatients: 1) ancestry from Asia or the original people from the Americas with lower metabolism (obesity or valproate) needing minimum therapeutic dosages of 75-150 mg/day, 2) ancestry from Asia or the original people from the Americas with average metabolism needing 175-300 mg/day, 3) European/Western Asian ancestry with lower metabolism (obesity or valproate) needing 100-200 mg/day, 4) European/Western Asian ancestry with average metabolism needing 250-400 mg/day, 5) in the US with ancestries other than from Asia or the original people from the Americas with lower clozapine metabolism (obesity or valproate) needing 150-300 mg/day, and 6) in the US with ancestries other than from Asia or the original people from the Americas with average clozapine metabolism needing 300-600 mg/day. Baseline and weekly CRP monitoring for at least four weeks is required to identify any inflammation, including inflammation secondary to clozapine rapid titration.

Cardiovascular Effects of High-Frequency Magnetic Seizure Therapy Compared With Electroconvulsive Therapy.

BACKGROUND: Magnetic seizure therapy (MST) is a novel convulsive therapy that has been shown to have antidepressant efficacy comparable to electroconvulsive therapy (ECT) with fewer cognitive side effects. However, the cardiovascular (CVS) effects of high frequency MST in comparison to ECT have not been investigated. MATERIALS AND METHODS: Forty-five patients with depression received 6 treatment sessions of 100 Hz MST versus 6 bifrontal ECT treatments in a nonrandomized comparative clinical design. Data on CVS function including heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), and rate pressure product (RPP) were collected at baseline (T0), after the induction of anesthesia but before the electrical stimulation (T1), during convulsion (T2), 2 minutes after cessation of motor seizure (T3), 5 minutes after cessation of motor seizure (T4), and 10 minutes after cessation of motor seizure (T5). Comparisons were made with baseline data and between MST and ECT groups. RESULTS: There were statistically significant elevations in the maximum HR, SBP, DBP, and RPP in patients receiving ECT compared with MST both in the initial and sixth treatments (all P < 0.05). Particularly, at T2, the ECT group had significantly higher HR, SBP, DBP, and RPP than those in MST group both in initial and sixth treatment (all P < 0.001). At the sixth treatment, the ECT group had significantly higher SBP, DBP, and RPP during the treatment than in the MST group (all P < 0.001). LIMITATIONS: The anesthetic choices for this study may limit the generalizability of our findings. The sample size was relatively small. CONCLUSIONS: Compared with ECT, high-frequency MST has fewer CVS side effects and may be a safer option for depression patients with CVS disorders.

LncRNA SNHG15 relieves hyperglycemia-induced endothelial dysfunction via increased ubiquitination of thioredoxin-interacting protein.

Numerous studies have revealed that hyperglycemia is a pivotal driver of diabetic vascular complications. However, the mechanisms of hyperglycemia-induced endothelial dysfunction in diabetes remain incompletely understood. This study aims to expound on the underlying mechanism of the endothelial dysfunction induced by hyperglycemia from the perspective of long non-coding RNAs (lncRNA). In this study, a downregulation of SNHG15 was observed in the ischemic hind limb of diabetic mice and high glucose (HG)-treated HUVECs. Functionally, the overexpression of SNHG15 promoted cell proliferation, migration, and tube formation, and suppressed cell apoptosis in HG-treated HUVECs. Mechanistically, SNHG15 reduced thioredoxin-interacting protein (TXNIP) expression by enhancing ITCH-mediated ubiquitination of TXNIP. TXNIP overexpression abrogated the protective effect of lncRNA SNHG15 overexpression on HG-induced endothelial dysfunction. The following experiment further confirmed that SNHG15 overexpression promoted angiogenesis of the ischemic hind limb in diabetic mice. In conclusion, SNHG15 is a novel protector for hyperglycemia-induced endothelial dysfunction via decreasing TXNIP expression.

Experimental Analysis of the Quality of Needle-Assisted Fenestration in Aortic Stent-Grafts and the Differences Between Gradual and Rapid Balloon Dilation.

Purpose: To report the findings of an in vitro experiment to evaluate the quality of needle fenestrations dilated by different size balloons in various stent-grafts and to investigate the differences between gradual and rapid dilation. Materials and Methods: Fenestrations were made using an 18-G needle in 5 different polyester or expanded polytetrafluoroethylene (ePTFE) stent-grafts: Relay, Valiant, Hercules, TAG, and Ankura. Each stent-graft received 2 groups of fenestrations: one was followed by gradual sequential dilation (4-, 6-, 8-, and 10-mm balloons) and the other by rapid dilation (4- and 10-mm balloons). The pressure was increased to 10 atmospheres or until the balloon was fully inflated with no waist. Quantitative and qualitative evaluations, including fenestration diameter, area, shape, and margins were conducted using light microscopy and scanning electron microscopy. Results: Relay had the strongest resistance to dilation and Ankura the slightest. The maximum length and area of holes expanded as the balloon diameter increased. The fenestrations in polyester devices were mostly elliptical or slit-like, with limited tears but extensive fibers visible in the margin, while ePTFE stent-grafts showed larger fenestration areas with clearer margins. Ankura showed the best quality of fenestrations, which were always circular or square without fabric tears, while the holes in the TAG were square or elliptical but sometimes had a slit after large balloon dilation (≥6 mm). The Relay, Valiant, Hercules, and Ankura devices showed no difference in maximum diameter, fenestration area, or scores of shape and margin (p>0.05). Rapid dilation in the TAG increased the rate of uncontrolled fabric tear, resulting in a larger final diameter (12.90 vs 10.82 mm, p=0.047), smaller area (30.46 vs 41.09 mm2, p=0.028), worse shape (0.75 vs 1.20, p=0.268), and worse margin (0.40 vs 1.00, p=0.174). Though the decreased fenestration shape and margin scores did not reach statistical significance, the trend for decline was more obvious than with the other devices. Conclusion: Materials and structures of the stent-grafts determine the quality of fenestrations dilated by different size balloons. The use of sequential vs rapid balloon dilation is also crucial for fashioning high-quality fenestrations and should be selected judiciously.

Burnout and job satisfaction of psychiatrists in China: a nationwide survey.

BACKGROUND: Despite a significant shortage of psychiatrists in China, an ever-increasing number of psychiatrists in China are experiencing burnout and job dissatisfaction and considering leaving their jobs. Yet, to our knowledge, there have been no nationwide studies to date that examined both burnout and job dissatisfaction of psychiatrists in China. Therefore, this study evaluated burnout and job dissatisfaction of psychiatrists in China, and identified relevant characteristics. METHODS: We conducted a nationwide, cross-sectional survey in March 2019. Psychiatrists from all tertiary psychiatric hospitals in China were invited to participate. The Maslach Burnout Inventory-Human Service Survey and the short version of the Minnesota Satisfaction Questionnaire were used to measure burnout and job satisfaction. Data on socio-demographic and occupational characteristics were collected. Multivariate logistic regression was conducted to identify socio-demographic and occupational characteristics associated with burnout and job satisfaction. RESULTS: In total, 4520 psychiatrists from tertiary psychiatric hospitals in China completed the questionnaire. Overall, 38.4% of respondents met the criteria for burnout and 35.6% were dissatisfied with their jobs. Being male, more years of practice, having no leadership role, and longer working hours per week were significantly associated with burnout and job dissatisfaction. Lower monthly pay was significantly associated with job dissatisfaction but not burnout. Moreover, burnout was significantly associated with job dissatisfaction. CONCLUSIONS: Our data suggest a high rate of burnout and job dissatisfaction among psychiatrists in China. In order to preserve and strengthen the mental health workforce, proactive measures are urgently needed to mitigate burnout and job dissatisfaction among psychiatrists in China.

Off-label use of antipsychotic medications in psychiatric inpatients in China: a national real-world survey.

BACKGROUND: The off-label use of antipsychotic medications is common in many countries, and the extent of such use in psychiatric inpatients in China has not been sufficiently studied. The purpose of this study was to survey the incidence and examine the correlates of off-label antipsychotic use in a large, nationally-representative sample in China. METHODS: This study included discharged psychiatric patients between March 19 and 31, 2019 from 41 tertiary psychiatric hospitals across 29 provinces in China. Their socio-demographic and clinical data were collected and analyzed. RESULTS: After excluding patients with schizophrenia spectrum disorder or bipolar disorder, 981 patients were included in the analysis. Overall, antipsychotics were prescribed to 63.2% (95%CI 60.2-66.2%) of the sample. Antipsychotics were used in a wide spectrum of psychiatric disorders, with the rate being the highest among patients with dissociative (conversion) disorders (89.9, 95%CI 83.0-94.8%), organic mental disorders (81.7, 95%CI 73.1-88.7%), dementia (79.0,95%CI 67.8-87.9%), obsessive-compulsive disorder (77.8, 95%CI 55.7-92.5%), mental disorders due to psychoactive substances (75.3,95%CI 64.7-84.2%), behavioural and emotional disorders with onset usually occurring in childhood and adolescence (71.4, 95%CI 45.5-90.1%), somatoform disorders (63.2, 95%CI 40.8%-82..2%), major depression disorder (53.7,95%CI 48.8-58.6%), anxiety disorder (38.8,95%CI 30.5-47.7%), and insomnia (25.0, 95%CI 8.5-28.9%). The top three most commonly used antipsychotics were olanzapine (29.1%), quetiapine (20.3%) and risperidone (6.8%), and their corresponding average doses were 9.04 ± 5.80 mg/day, 185.13 ± 174.72 mg/day, and 2.98 ± 1.71 mg/day, respectively. A binary logistic regression showed that younger age, having the Employee Health Insurance or Residents Health Insurance, having psychotic symptoms and requiring restraint during hospitalization were significantly associated with off-label use of antipsychotics. CONCLUSION: Off-label use of antipsychotics is very common in psychiatric inpatients in China, mainly with moderate-dose use of single agents. However, the efficacy and safety of this practice is uncertain for many diagnoses and for the elderly. Clinicians should be cautious about this practice while waiting for more research data.

Alcohol Use Among Mental Health Professionals in China: A Nationwide Cross-sectional Survey.

AIM: To survey the use of alcohol, and its correlates by mental health professions in China, a nation where there is rapid increase in alcohol consumption and problems. METHODS: As a part of a large-scale, nation-wide online survey of healthcare professionals, we collected demographic variables and other health-related variables anonymously. The Alcohol Use Disorder Identification Test-Concise (AUDIT-C) was used to collect data on alcohol use. RESULTS: 13,980 mental health professionals completed the survey (4382 doctors, 9339 nurses and 259 clinical psychologists), representing 64% of the total targeted. Respondents were predominantly female (75.1%). Alcohol consumption was reported by 41.8% of participants (by 53.9% of doctors, 36.2% of nurses and 40.5% of clinical psychologists). Based on the cut-off scores of the AUDIT-C (≥3 for women and ≥4 for men), 7.5% were classified as probable alcohol misusers in the past year, and the rates were 10.2% in doctors, 6.3% in nurses and 5.8% in clinical psychologists. Multiple logistic regression showed that male sex (OR = 3.772; CI = 3.206-4.439), being a doctor (OR = 1.259; CI = 1.052-1.506), being divorced or widowed (OR = 1.979; CI = 1.467-2.666), having an associate degree or less (OR = 1.809; CI = 1.040-3.147), working in Northeast China (OR = 1.538; CI = 1.281-1.848) and the habit of smoking (OR = 3.345; CI = 2.280-3.967) were significantly associated with alcohol misuse. CONCLUSIONS: Alcohol use and misuse were relatively common among mental health professionals in China, and male sex, being a doctor, with lower education, working in Northeast China and cigarette smoking were significant associations. Awareness and interventions are recommended to promote healthier use of alcohol in this professional group, especially among risk subgroups.

Elevated Rates of Restraint and Seclusion in Child and Adolescent Psychiatric Inpatients in China and Their Associated Factors.

To investigate the rate of restraint and seclusion (R&S) use in child and adolescent psychiatric inpatients in China and to examine factors associated with use of these interventions. As part of an official national survey, 41 provincial tertiary psychiatric hospitals in China were selected. Data from 196 youth inpatients discharged from these hospitals from March 19 to 31, 2019 were retrieved and analyzed. (1) The overall rate of R&S was 29.1% (N = 57) and the rate of restraint was 28.6% (N = 56), and seclusion was 11.7% (N = 23) respectively. (2) Compared to patients who did not require R&S, those who required R&S were more likely to have been hospitalized on an involuntary basis, more likely to present with either manic symptoms or aggressive behavior as primary reason for admission, had more frequent aggressive behaviors during hospitalization, and had a significantly longer length of stay. (3) A logistic regression showed that aggressive behaviors during hospitalization was significantly associated with the use of R&S (OR = 21.277, p < 0.001), along with three other factors: manic symptoms as a reason for admission, involuntary admission and a lower GAF score at admission (all p < 0.01). The rate of R&S is dramatically higher in child and adolescent psychiatric hospitalizations in China compared to other regions. Targeted training of staff, development of precise operational guidelines for appropriate use of R&S, and strict oversight are urgently needed to minimize the inappropriate use of R&S in child and adolescent patients.

Maximum strength levels for pulling and pushing handleless cartons in warehousing tasks.

This study examined the variation in individuals' static maximum forward pushing and backward pulling (FPBP) strength for handleless cartons under different task conditions. Thirty young Taiwanese men were recruited as participants and were requested to perform maximum FPBP exertion tests under four exertion heights (50, 80, 110, and 140 cm), two types of hand contact (bare hands and gloves), and two carton widths (40 and 60 cm). The results of this study indicated that the pushing strength for handleless cartons was almost twice the pulling strength for all exertion heights. This finding is different from those of previous relevant studies. The pulling force generated when gloves were worn was 38% higher than that generated under barehanded pulling. Moreover, the pulling force generated with a 40-cm-wide carton was 13% higher than that generated with a 60-cm-wide carton. Pushing strength was affected by only the exertion height. Practitioner Summary: We examined the effects of exertion height, carton width, and type of contact on the maximum FPBP strengths. Pulling strength should be considered first for the related task design because it is lower than pushing strength. However, pulling strength can be maximised by wearing gloves to pull a 60-cm-wide carton. Abbreviations: FPBP: forward pushing and backward pulling; ANOVA: analysis of varianceHIGHLIGHTSMaximum forward pushing and backward pulling (FPBP) forces vary for cartons.FPBP forces for force direction, contact type, carton width, and exertion height were examined.FPBP forces generated for handleless cartons differ from those generated for cartons with handles.Pulling strength can be maximised by wearing gloves and using a 60-cm-wide carton.Gloves are useful tools for pulling handleless cartons.

Synthesis of Ordered Pt Nanocube Arrays Directed by Block Copolymer Nanotemplate and Their Potential on Ethanol Oxidation Reaction.

In this work, well-ordered platinum (Pt) nanocubes (NCs), with precise control on the size and the spatial arrangement, are synthesized from a microemulsion overgrowth in a block copolymer (BC) nanotemplate. The nanovials on this self-assembled BC template serve as microreactors for the reduction of the HCl/H2PtCl6 precursor and direct the ordered periodic arrangement of the reduced Pt nanoparticles (NPs). As the content of HCl increases from 0% to 25%, the Pt NPs evolve from quasi-spheres to NCs, for which the density functional theory (DFT) computation reveals that the different adsorption energies of Cl and HCl dominate this morphology transition. For their potential application in fuel cells, the electrochemical catalysis of the Pt NCs demonstrates a 2.8-fold mass activity in contrast to the commercial JM 40% catalyst at the same Pt loading in ethanol oxidation reaction (EOR) and a good stability of 2.2% ECSA loss over 10 000 CV cycling.
