Clinical Significance of Serum Visfatin in Renal Transplant Recipients.

Chronic antibody-mediated rejection is the most common cause of late graft loss in renal transplant recipients. Visfatin is a pre-B cell colony-enhancing factor secreted by activated lymphocytes. We hypothesize that visfatin may play a role in the augmentation of B cell colonies and facilitate antibody-mediated rejection. Renal transplant recipients were randomly selected for the study. Fasting blood samples were obtained for the assay of visfatin. The participants were prospectively followed up for 3 years. A total of 146 patients were recruited for the study and were divided into 3 groups according to tertile of serum visfatin level. At the end of follow-up, 6 patients had graft loss, including 1 graft loss in tertile 1, 3 in tertile 2, and 2 in tertile 3 (P = .60). Fourteen patients experienced at least 1 episode of acute rejection, while 21 patients were diagnosed as having chronic rejection. The distribution of acute rejection was 10.2% in tertile 1, 10.2% in tertile 2, and 8.3% in tertile 3 (P = .94); chronic rejection occurred in 10.2%, 16.3%, and 16.7%, respectively (P = .59). We conclude that serum visfatin level was not correlated with either graft failure or patient mortality in a 3-year observation period.

Common mental health problems in rural-to-urban migrant workers in Shenzhen, China: prevalence and risk factors.

AIMS: Rural-to-urban migrant workers are a large marginalised population in urban China. Prevalence estimates of common mental health problems (CMHPs) in previous studies varied widely and very few studies have investigated migration-related factors of CMHPs in migrant workers. The objective of this study was to determine the prevalence and risk factors of CMHPs among Chinese migrant workers. METHODS: A random sample of 3031 migrant workers of ten manufacturing factories in Shenzhen, China, completed a standardised questionnaire containing socio-demographic and migration-related variables and the Chinese 12-item General Health Questionnaire (GHQ-12). A GHQ-12 score of three or higher was used to denote the presence of CMHPs. RESULTS: The prevalence of CMHPs was 34.4% in Chinese migrant workers. In multiple logistic regression, risk factors for CMHPs included being 16-25 years old (odd ratio [OR] 1.65, 95% confidence interval [CI] 1.28, 2.12), being 26-35 years old (OR 1.36, 95% CI: 1.05, 1.75), low monthly income (OR 1.42, 95% CI 1.04, 1.92), poor living condition (OR: 1.76, 95% CI: 1.22, 2.54), physical illness in the past 2 weeks (OR 1.72, 95% CI 1.43, 2.05), having worked in many cities (OR 1.34, 95% CI 1.03, 1.74), infrequently visiting hometown (OR 1.56, 95% CI 1.22, 1.99), poor Mandarin proficiency (OR 1.51, 95%CI 1.13, 2.01), a low level of perceived benefits of migration (OR 1.33, 95% CI 1.14, 1.55) and working more than 8 h/day (OR 1.39, 95% CI 1.14, 1.70). CONCLUSIONS: CMHPs are very prevalent among Chinese migrant workers. Given the large number of Chinese migrant workers, there is an urgent need to address the mental health burden of China's migrant worker population.

Efficacy and safety of adjunctive topiramate for schizophrenia: a meta-analysis of randomized controlled trials.

OBJECTIVE: To systematically examine the randomized controlled trial (RCT) evidence regarding efficacy and tolerability of topiramate cotreatment with antipsychotics in schizophrenia-spectrum disorders. METHODS: Random-effects meta-analysis of RCTs of topiramate cotreatment with antipsychotics vs. placebo/ongoing antipsychotic treatment in schizophrenia-spectrum disorders. Standardized or weighted mean difference (SMD/WMD), risk ratio (RR) ±95% confidence intervals (CIs), and number needed to harm (NNH) were calculated. RESULTS: Across 16 RCTs (n = 934, duration = 11.8 ± 5.6 weeks), topiramate outperformed the comparator regarding change/endpoint of total (SMD: -0.58, 95% CI: -0.82, -0.35, P < 0.00001), positive (SMD: -0.37, 95% CI: -0.61, -0.14, P = 0.002), negative (SMD: -0.58, 95% CI: -0.87, -0.29, P < 0.0001), and general symptoms (SMD: -0.68, 95% CI: -0.95, -0.40, P < 0.00001). Furthermore, topiramate was superior regarding body weight (WMD: -2.75 kg, 95% CI: -4.03, -1.47, P < 0.0001), body mass index (BMI) (WMD: -1.77, 95% CI: -2.38, -1.15, P < 0.00001), triglycerides (P = 0.006), and insulin levels (P < 0.00001). Superiority regarding psychopathology and body weight/BMI was consistent across Chinese/Asian and Western RCTs, double-blind and open designs, clozapine and non-clozapine cotreatment, augmentation and co-initiation RCTs, and higher and lower quality RCTs. In meta-regression analyses, topiramate's efficacy for total symptoms was moderated by shorter illness duration (P = 0.047), while weight loss was greater in prevention/co-initiation vs. intervention/augmentation RCTs (-4.11 kg, 95% CI: -6.70, -1.52 vs. -1.41 kg, 95% CI: -2.23, -0.59, P < 0.001). All-cause discontinuation was similar between topiramate and comparators (RR: 1.28, 95% CI: 0.91, 1.81, P = 0.16). While topiramate led to more concentration/attention difficulties (P = 0.03, NNH = 8, 95% CI=4-25), psychomotor slowing (P = 0.02, NNH = 7, 95% CI = 4-25), and paresthesia (P = 0.05, NNH = 2, 95% CI = 4-33), it led to less ≥7% weight gain (P = 0.0001, NNH = 2, 95% CI = 2-3) and constipation (P = 0.04, NNH = 9, 95% CI = 5-100) than the comparator. CONCLUSIONS: These results indicate that adjunctive topiramate to antipsychotics is an effective and safe treatment choice for symptomatic improvement and weight reduction in patients with schizophrenia-spectrum disorders.

Prognosis of Kidney Transplant Recipients With Pretransplantation Malignancy: A Nationwide Population-Based Cohort Study in Taiwan.

OBJECTIVE: The objective of this study was to evaluate the prognosis of kidney transplant recipients with pretransplantation malignancy and the incidence of recurrent malignancy in kidney transplant recipients using claims data from Taiwan's universal health insurance program. METHOD: A total of 4350 transplant recipients were retrospectively analyzed. The rates of pretransplantation or recurrent malignancy, which was defined by their inclusion in the catastrophic illness patient registry using the International Classification of Diseases, 9th Revision, were evaluated. Cox proportional hazard regression and Kaplan-Meier curves were used for the analyses. RESULTS: In total, there were 4350 kidney transplant recipients, 52.1% of patients were male, the mean age at transplantation was 45.8 years old, and the percentages of diabetes mellitus, hypertension, hepatitis B viral infection, and hepatitis C viral infection were 14%, 63.2%, 4.2%, and 2.4%, respectively. There were 95 patients (2.2%) with pretransplantation malignancy. The top 3 pretransplantation malignancies, in decreasing order, were urinary tract, kidney, and breast cancers. After kidney transplantation, 10 recipients had recurrent cancer. The overall cancer recurrence rate was 10.5%. These 10 cancers included urothelial carcinoma (n = 5), renal cell carcinoma (n = 3), breast cancer (n = 1), and thyroid cancer (n = 1). Eleven recipients had a secondary cancer. Patients without pretransplantation and post-transplantation malignancy had the best survival. Patients with pretransplantation malignancy had a greater occurrence of cancers and increased mortality regardless of whether or not they had recurrence of cancer. CONCLUSION: Our results suggest the higher risk of cancer, recurrent or secondary, and mortality after kidney transplantation. Adequate waiting time before transplantation and preventive strategies are strongly suggested in kidney transplant recipients with cancer history.

Prescribing Pattern of Antidepressants in Children and Adolescents: Findings from the Research on Asia Psychotropic Prescription Pattern.

OBJECTIVE: Pharmacotherapy of depression in children and adolescents is complex. In the absence of research into the efficacy and safety of antidepressants in this group of patients, their off-label prescription is common. This paper aimed to illustrate the prescription pattern of antidepressants in children and adolescents from major psychiatric centres in Asia. METHODS: The Research on Asia Psychotropic Prescription Pattern on Antidepressants worked collaboratively in 2013 to study the prescription pattern of antidepressants in Asia using a unified research protocol and questionnaire. Forty psychiatric centres from 10 Asian countries / regions participated and 2321 antidepressant prescriptions were analysed. RESULTS: A total of 4.7% antidepressant prescriptions were for children and adolescents. Fluoxetine, sertraline, and escitalopram were the most common antidepressants prescribed for children and adolescents. Almost one-third (30.3%) of prescriptions were for diagnoses other than depressive and anxiety disorders. There was less antidepressant polypharmacy and concomitant use of benzodiazepine, but more concomitant use of antipsychotics in children and adolescents compared with adults. CONCLUSION: Off-label use of antidepressants in children and adolescents was reported by 40 Asian psychiatric institutions that participated in the study. In-service education and regulatory mechanisms should be reinforced to ensure efficacy and safety of antidepressants in children and adolescents.

Extract of Ginkgo biloba for Tardive Dyskinesia: Meta-analysis of Randomized Controlled Trials.

OBJECTIVE: Free radicals may be involved in the pathogenesis of tardive dyskinesia (TD). We conducted this meta-analysis to systematically examine the efficacy of extract of Ginkgo biloba (EGb), a potent antioxidant possessing free radical-scavenging properties, as a treatment for TD in schizophrenia using randomized controlled trial (RCT) data. METHOD: Drawn from English and Chinese databases, 3 RCTs of EGb augmentation of antipsychotics (APs) vs. AP plus placebo or AP monotherapy were identified. 2 evaluators extracted data. The primary outcome measure was the severity of TD symptoms assessed by the Abnormal Involuntary Movement Scale (AIMS). Weighted mean difference (WMD) and risk ratio (RR) ±95% confidence intervals (CI) were calculated. Statistical analyses were performed using Review Manager (version 5.1.7.0) and STATA (version 12.0). RESULTS: The 3 RCTs (n=299) from China, of 12 weeks duration, involved schizophrenia patients with TD of 55.9±13.4 years old. EGb (240 mg/day) outperformed the control group in reducing the severity of TD and clinical symptoms as measured by the AIMS (trials=3, n=299, WMD: -2.30 (95%CI: - 3.04, -1.55), P<0.00001) and the adverse drug reactions as assessed by the Treatment Emergent Symptom Scale (TESS) (trials=2, n=142, WMD: -2.38 (95%CI: -4.01, -0.74), P=0.004). Both the Positive and Negative Syndrome Scale (PANSS) total score (trials=2, n=239, P=0.87) and all-cause discontinuation (trials=3, n=299, P=0.21) were similar between the EGb and control group. CONCLUSION: This meta-analysis suggests that adjunctive EGb appeared to be an effective and safe option for improving TD in the treatment of schizophrenia patients. However, better RCTs are needed to demonstrate its efficacy and safety especially on cognitive function in TD. PROSPERO: CRD42015024930.

Single i.v. ketamine augmentation of newly initiated escitalopram for major depression: results from a randomized, placebo-controlled 4-week study.

BACKGROUND: While oral antidepressants reach efficacy after weeks, single-dose intravenous (i.v.) ketamine has rapid, yet time-limited antidepressant effects. We aimed to determine the efficacy and safety of single-dose i.v. ketamine augmentation of escitalopram in major depressive disorder (MDD). METHOD: Thirty outpatients with severe MDD (17-item Hamilton Rating Scale for Depression total score ⩾ 24) were randomized to 4 weeks double-blind treatment with escitalopram 10 mg/day+single-dose i.v. ketamine (0.5 mg/kg over 40 min) or escitalopram 10 mg/day + placebo (0.9% i.v. saline). Depressive symptoms were measured using the Montgomery-Asberg Depression Rating Scale (MADRS) and the Quick Inventory of Depressive Symptomatology - Self-Report (QIDS-SR). Suicidal ideation was evaluated with the QIDS-SR item 12. Adverse psychopathological effects were measured with the Brief Psychiatric Rating Scale (BPRS)-positive symptoms, Young Mania Rating Scale (YMRS) and Clinician Administered Dissociative States Scale (CADSS). Patients were assessed at baseline, 1, 2, 4, 24 and 72 h and 7, 14, 21 and 28 days. Time to response (⩾ 50% MADRS score reduction) was the primary outcome. RESULTS: By 4 weeks, more escitalopram + ketamine-treated than escitalopram + placebo-treated patients responded (92.3% v. 57.1%, p = 0.04) and remitted (76.9% v. 14.3%, p = 0.001), with significantly shorter time to response [hazard ratio (HR) 0.04, 95% confidence interval (CI) 0.01-0.22, p < 0.001] and remission (HR 0.11, 95% CI 0.02-0.63, p = 0.01). Compared to escitalopram + placebo, escitalopram + ketamine was associated with significantly lower MADRS scores from 2 h to 2 weeks [(peak = 3 days-2 weeks; effect size (ES) = 1.08-1.18)], QIDS-SR scores from 2 h to 2 weeks (maximum ES = 1.27), and QIDS-SR suicidality from 2 to 72 h (maximum ES = 2.24). Only YMRS scores increased significantly with ketamine augmentation (1 and 2 h), without significant BPRS or CADSS elevation. CONCLUSIONS: Single-dose i.v. ketamine augmentation of escitalopram was safe and effective in severe MDD, holding promise for speeding up early oral antidepressant efficacy.

Trends in the access to and the use of antipsychotic medications and psychotropic co-treatments in Asian patients with schizophrenia.

To date, antipsychotics remain the mainstay of treatment for schizophrenia and related disorders although other psychotropic medications and non-pharmaceutical interventions have been used adjunctively in some patients and settings. Regular surveys on access to and prescription patterns of psychotropic medications in clinical practice are an important and efficient way of examining the use and time trends of treatments in a given population and region. Unlike developed Western countries, Asian countries have not fully undergone deinstitutionalisation of the severely and chronically mentally ill, and community-based mental health services are still under-developed. As a result, a large number of psychiatric patients still receive treatments in psychiatric hospitals. Moreover, there have been very limited studies examining access to and prescription patterns of psychotropic medications for schizophrenia patients in Asian countries. In this paper, we focus on the only international project on the use of psychotropic medications in schizophrenia patients in selected East and Southeast Asian countries/territories summarising its major findings. Most of the first- and second-generation antipsychotics (FGAs and SGAs) are available in Asian countries, but the access to psychotropic medications is largely affected by socio-cultural and historical contexts, health insurance schemes, health care policy, medication cost and consumers' preference across different countries/territories. Overall, the proportional use of FGAs, high dose antipsychotic treatment and antipsychotic polypharmacy have decreased, while the use of SGAs and antidepressants have increased and the utilisation of benzodiazepines and mood stabilisers has remained relatively stable over time. However, within these general trends, there is great inter-country variation regarding the psychotropic prescribing patterns and trends in Asian schizophrenia patients that also seems to differ from data in many Western countries.

Frequency and Correlates of Distant Visual Impairment in Patients with Schizophrenia, Bipolar Disorder, and Major Depressive Disorder.

OBJECTIVE: Distant visual impairment in the severely mentally ill is under-researched. This study aimed to assess the frequency and correlates of distant visual impairment in a cohort of Chinese psychiatric patients, including its effect on their quality of life. METHODS: Adult psychiatric inpatients with schizophrenia, bipolar disorder, and major depressive disorder consecutively admitted to a psychiatric hospital in Beijing, China underwent assessments of psychopathology (Brief Psychiatric Rating Scale, 16-item Quick Inventory of Depressive Symptomatology [Self-Report]), quality of life (12-item Short-Form Medical Outcomes Study [SF-12], 25-item National Eye Institute Visual Function Questionnaire [NEI-VFQ25]), adverse effects (Udvalg for Kliniske Undersøgelser Side Effect Rating Scale), and presenting (as opposed to uncorrected) distant visual acuity (Logarithm of the Minimum Angle of Resolution [LogMAR] chart with patients wearing spectacles, if they owned them). Distant visual impairment was defined as binocular distant visual acuity of a LogMAR score of ≥ 0.5 (< 6/18 Snellen acuity). RESULTS: Among 356 patients who met the study criteria, the frequency of distant visual impairment was 12.6% (15.2% with schizophrenia, 11.9% with bipolar disorder, 8.8% with major depressive disorder). In multiple logistic regression analysis, distant visual impairment was significantly associated with ocular disease only (p = 0.002, odds ratio = 3.2, 95% confidence interval = 1.5-6.7). Controlling for the confounding effect of ocular disease, patients with distant visual impairment had a lower quality of life in the general vision domain of the NEI-VFQ25 (F[2, 353] = 9.5, p = 0.002) compared with those without. No differences in the physical and mental domains of the SF-12 and in other domains of the NEI-VFQ25 were noted in these 2 groups. CONCLUSION: One-eighth of middle-aged severely mentally ill patients had distant visual impairment. Considering the impact of distant visual impairment on daily functioning, severely mentally ill patients need to be screened for impaired eyesight as part of their comprehensive health assessment.

Clozapine prescription and quality of life in Chinese patients with schizophrenia treated in primary care.

OBJECTIVE: Clozapine is frequently used to treat schizophrenia in China. Maintenance treatment for clinically stable patients with schizophrenia is usually provided by Chinese primary care physicians, but no study has investigated the frequency of its use prescribed by primary care physicians. This study described the frequency, demographic and clinical characteristics of clozapine treatment and its impact on insight and quality of life (QOL) of patients with schizophrenia treated in primary care in China. METHOD: A total of 623 patients with schizophrenia treated in 22 primary care services in Guangzhou, China in 2013 formed the study sample. Patients' socio-demographic and clinical characteristics including psychopathology, medication side effects and QOL were recorded using a standardized protocol and data collection. RESULTS: The frequency of clozapine prescription was 35.6% with a mean daily dose of 127.7±88.2 mg. There were no significant differences between the patients with and without clozapine in either of the QOL domains after controlling the confounding factors. Multiple logistic regression analyses revealed that patients on clozapine had younger age of onset, more hospitalizations, more severe extrapyramidal side effects, but better insight and fewer prescriptions of first generation antipsychotics. CONCLUSIONS: Clozapine use was found to be common and associated with better insight in patients with schizophrenia treated in primary care in China. Further examination of the rationale and appropriateness of clozapine in primary care in China is warranted.

The Chinese First-Episode Schizophrenia Trial: background and study design.

Schizophrenia is a complex illness with unknown aetiology and pathogenesis. Currently, a considerable number of patients with schizophrenia do not receive standardised and systematic treatment in China. In the past years, many controlled trials have been conducted in chronic schizophrenia. In contrast, research on first-episode schizophrenia is lacking. This paper describes the background and design of the Chinese First-Episode Schizophrenia Trial project--a multicentre, randomised, open-label clinical trial. A total of 600 first-episode schizophrenia patients were randomly divided into 3 groups and treated with risperidone, aripiprazole, and olanzapine for 1 year. During the study period, only 1 medication change of the 3 antipsychotic medications was allowed.

The Hong Kong mental morbidity survey: background and study design.

Mental disorders are highly prevalent conditions with immense disease burden. To inform health and social services policy formulation, local psychiatric epidemiological data are required. The Hong Kong Mental Morbidity Survey is a 3-year population-based study in which 5700 community-dwelling Chinese adults aged between 16 and 75 years were interviewed with the aim of evaluating the prevalence, co-morbidity, functional impairment, physical morbidity, and social determinants of significant mental disorders in the population. This paper describes the background and design of the survey, and is the first territory-wide psychiatric epidemiological study in Hong Kong.

Characteristics of unrecognised bipolar disorder in patients treated for major depressive disorder in China: general versus psychiatric hospitals.

OBJECTIVES: Bipolar disorder is often misdiagnosed as major depressive disorder. Such misdiagnosis partly depends on the type of treatment setting. This study compared general hospital psychiatric units with psychiatric hospitals in China with respect to basic demographic and clinical characteristics of patients with unrecognised bipolar disorder who are treated for major depressive disorder. METHODS: Patients treated for major depressive disorder were consecutively examined in 13 health centres (6 general hospital psychiatric units and 7 psychiatric hospitals) in China. Their socio-demographic and clinical features were recorded using a standardised protocol and data collection procedure. The DSM-IV diagnoses were established using the Mini-International Neuropsychiatric Interview. RESULTS: Of the 1487 patients included in the study, 309 (20.8%) were diagnosed with bipolar disorder. There was no significant difference between general hospital psychiatric units and psychiatric hospitals in the ratio of all types of unrecognised bipolar disorders (χ2 = 0.008, degrees of freedom = 1, p = 0.9) and bipolar II disorders (χ2 = 3.1, degrees of freedom = 1, p = 0.08). The proportions of unrecognised bipolar I disorders (χ2 = 4.1, degrees of freedom = 1, p = 0.04) differed significantly between the 2 types of study site. Multivariate analyses showed that patients with bipolar I disorders with more seasonal depressive episodes were more likely to receive treatment in general hospital psychiatric units (odds ratio = 3.3, 95% confidence interval = 1.1-9.8). CONCLUSION: Patients with bipolar I disorders receiving treatment in general hospital psychiatric units had different clinical characteristics compared to their counterparts treated in psychiatric hospitals in China.

Assessing mental capacity for everyday decision-making in the Chinese older population.

1. The abilities to make everyday decisions may be reliably measured in the local elderly population. 2. The Chinese version of the Assessment of Capacity for Everyday Decision-Making is a reliable tool to assess these abilities. 3. Significant proportion of participants with mild dementia was mentally incapable in making decisions on everyday tasks. Global cognitive functioning appeared to be an important prerequisite for intact mental capacity.

Adjunctive mood stabilizer and benzodiazepine use in older Asian patients with schizophrenia, 2001-2009.

OBJECTIVE: This study surveyed the use of adjunctive mood stabilizers (MS) and benzodiazepines (BZD) in older Asian schizophrenia patients and examined their demographic and clinical correlates. METHOD: Information on hospitalized schizophrenia patients aged 55 years or more were extracted from the database of the Research on Asian Psychotropic Prescription Patterns (REAP) study. A total of 1,452 patients from 9 Asian countries and territories was included in the study. The patients' sociodemographic and clinical characteristics and the prescriptions of antipsychotics, MS and BZD were recorded using a standardized protocol and data collection procedure. RESULTS: The frequency of MS prescription was 26.7% in the pooled sample, with 25.5% in 2001, 26.9% in 2004 and 27.7% in 2009. The corresponding figures for BZD were 20.7%, 20.2%, 18.4% and 23.1%, respectively. Multiple logistic regression analysis of the whole sample revealed that patients on MS were younger and more likely to be men and to have extrapyramidal side effects (EPS) and a longer duration of illness. Compared to patients in China, those in Japan were more likely to receive MS, while Korean patents were prescribed less MS. In contrast, there were no significant sociodemographic or clinical correlates of BZD use. Compared to patients in China, their Korean and Singaporean counterparts were more likely to be on BZD. CONCLUSIONS: The use of MS and BZD is not uncommon in older Asian patients with schizophrenia. Given the paucity of empirical data on the efficacy of these agents in individuals with schizophrenia of any age and concerns about added side effects in older patients in particular, the rationale for the prescription of these agents in this population warrants further examination.

Suicidal thoughts and behaviors in older adults in rural China: a preliminary study.

BACKGROUND: One purpose of this study was to examine the feasibility of conducting epidemiological survey on suicidal thoughts and behaviors (hereafter "suicidal thoughts/behaviors"; i.e., any suicidal ideation, serious ideation, planning, and attempts) among older adults in rural China. Another purpose was to investigate among older people in rural China the prevalence of suicidal thoughts/behaviors, as well as their sociodemographic and clinical correlates. METHODS: A randomly selected sample of 263 subjects, 50 years or older, was recruited in a remote rural area of Southwestern China (Mianyang Region, Sichuan Province) and interviewed using structured instruments. Basic sociodemographic and clinical data were collected. RESULTS: There was no refusal among approached subjects, and subjects were willing to answer questions on suicidal thoughts/behaviors. The lifetime prevalence of suicidal ideation, serious ideation, planning, and attempt was 28.9% (23.4%-34.4%), 19.7% (14.9%-24.6%), 11.4% (7.5%-15.3%), and 5.3% (2.6%-8.1%), respectively. The corresponding 12-month prevalence was 8.8% (5.3%-12.2%), 5.3% (2.6%-8.1%), 2.7% (0.7%-4.6%), and 0%, respectively. The 2-week prevalence was 3.4% (1.2%-5.6%), 2.3% (0.5%-4.1%), 2.3% (0.5%-4.1%), and 0%, respectively. Correlates of suicidal thoughts/behaviors of this group are similar to findings from other community studies, such as female gender, unmarried status, major medical conditions, insomnia, financial difficulties and lower education, depressive symptoms, recent stressful life events, greater life dissatisfaction. CONCLUSIONS: Our findings suggest that larger scale epidemiological survey of suicidal thoughts/behaviors on older adults in rural China would be feasible. Suicidal thoughts/behaviors are common among older people in rural China, as seen in this preliminary study, which points to the need for further larger scale investigations.

Effects of a Chinese medical herbs complex on cellular immunity and toxicity-related conditions of breast cancer patients.

Rose geranium (Pelargonium graveolens, Geraniaceae) has anti-cancer and anti-inflammatory properties, and promotes wound healing. Similarly, Ganoderma tsugae (Ganodermataceae), Codonopsis pilosula (Campanulaceae) and Angelica sinensis (Apiaceae) are traditional Chinese herbs associated with immunomodulatory functions. In the present study, a randomised, double-blind, placebo-controlled study was conducted to examine whether the Chinese medicinal herb complex, RG-CMH, which represents a mixture of rose geranium and extracts of G. tsugae, C. pilosula and A. sinensis, can improve the immune cell count of cancer patients receiving chemotherapy and/or radiotherapy to prevent leucopenia and immune impairment that usually occurs during cancer therapy. A total of fifty-eight breast cancer patients who received chemotherapy or radiotherapy were enrolled. Immune cell levels in patient serum were determined before, and following, 6 weeks of cancer treatment for patients receiving either an RG-CMH or a placebo. Administration of RG-CMH was associated with a significant reduction in levels of leucocytes from 31·5 % for the placebo group to 13·4 % for the RG-CMH group. Similarly, levels of neutrophils significantly decreased from 35·6 % for the placebo group to 11·0 % for the RG-CMH group. RG-CMH intervention was also associated with a decrease in levels of T cells, helper T cells, cytotoxic T cells and natural killer cells compared with the placebo group. However, these differences between the two groups were not statistically significant. In conclusion, administration of RG-CMH to patients receiving chemotherapy/radiotherapy may have the capacity to delay, or ease, the reduction in levels of leucocytes and neutrophils that are experienced by patients during cancer treatment.

Antipsychotic polypharmacy in inpatients with schizophrenia in Asia (2001-2009).

OBJECTIVE: This study aimed to identify trends in the use of antipsychotic polypharmacy (APP) and their demographic and clinical correlates in the treatment of schizophrenia in Asia between 2001 and 2009. METHOD: A total of 6,761 schizophrenia inpatients in 9 Asian countries and territories were examined; 2,399 in 2001, 2,136 in 2004, and 2,226 in 2009. Patients' socio-demographic and clinical characteristics and prescriptions of psychotropic drugs were recorded using a standardized protocol and data collection procedure. RESULTS: The proportion of APP prescription decreased from 46.8 % in 2001, to 38.3 % in 2004, and increased to 43.4 % in 2009, with wide intercountry variations at each survey. Multiple logistic regression analysis of the whole sample revealed that patients on APP were younger, had a higher dose of antipsychotics in chlorpromazine equivalents, and more severe positive and negative symptoms. They were also more likely to receive depot and fi rst-generation antipsychotic drugs. CONCLUSIONS: The frequency of APP prescription varied between countries and territories, suggesting that a host of clinical and socio-cultural factors played a role in determining APP use in Asia. To resolve the discrepancy between treatment recommendation and clinical practice, regular reviews of prescription patterns are needed.
