Development and Evaluation of Psychometric Properties Regarding the Whole Person Health Scale for Employees of Hospital to Emphasize the Importance of Health Awareness of the Workers in the Hospital.

(1) Background: Whole person health (WPH) is important among employees in hospitals. It will affect their performance and attitude toward patient care and organization. This project was designed to develop and assess the validity and reliability of utilizing the Whole Person Health Scale for Employees of a Hospital (WPHS-EH) to determine overall employee health. (2) Methods: A mixed-methods focus group and cross-sectional survey was adopted. Employees held six focus groups, with 62 employees from different departments in medical center in Taiwan. After analyzing the interview content, five experts tested its validity, and the 14-item WPHS-EH scale was analyzed. This was followed by an additional 900 participants questionnaire survey, response rate: 94.9%. Descriptive statistics, Cronbach's alpha, exploratory factor analysis (EFA), and items analysis were used. Additionally, the scale was implemented to conducted confirmatory factor analysis (CFA) test for validity. (3) Results: Three dimensions were extracted from the questionnaires by EFA: "hospital circumstance and system", "professional and interpersonal interaction" and "workload and harm". The Cronbach's alpha of the WPHS-EH scale was 0.82, while the three sub-dimensions were all significantly correlated with total scores. CFA confirmed the scale construct validity, with a good model fit. (4) Conclusions: The WPHS-EH is a reliable measurement tool to assess the effects of hospitals' Whole Person Health among employees. The intent of the WPHS-EH was to provide a reliable scale to analyze the work environment for hospital staff and useful information to healthcare administrators interested in improving the staff's whole person health.

Associations of diabetes severity and risk of depression: a population-based cohort study.

OBJECTIVE: Previous literature investigating effects of diabetes complications on subsequent depression have been inconsistent. We aim to investigate associations of diabetes, complication severity, and depression. DESIGN: This study used a nationwide database to establish an 11-year cohort comprised of people with new onset Type II diabetes mellitus (DM) aged 20 and above. METHOD: Severity of DM was measured using the adapted Diabetes Complication Severity Index (aDCSI). Status of depression was determined by having one recorded depression diagnosis from the inpatient setting or three recorded depression diagnoses from the outpatient setting. The risk of depression was analyzed by multivariate Cox proportional models. RESULTS: In 50,590 cases with new onset DM from years 2000 to 2011, the incidence of depression increased with severity and rates of progressions in diabetes complications regardless of demographic status, comorbidities, or medication compliance. Adjusted hazard ratios (aHR) of depression were 1.21, 1.25, 1.48 (p<0.001 for trend) in patients with a total aDCSI score of 1, 2, and > 3, respectively. Risks of depression were the highest in subgroup with the most serious progression (change of aDCSI score >2 per year) (aHR ranged between 11.6~26.0). Elevated risks of depression (aHR: 1.59~4.36) were also observed in the slower progression subgroups throughout the disease course. CONCLUSIONS: Risks of depression were associated with multiple DM-related complications and rates of progression in severity.

Serial multiple mediation of demoralization and depression in the relationship between hopelessness and suicidal ideation.

OBJECTIVE: Suicidal ideation is common in cancer patients and may be associated with hopelessness, demoralization, and depression. This study aims to investigate the serial multiple mediation of demoralization and depression in the relationship between hopelessness and suicidal ideation in cancer patients. METHODS: A total of 244 cancer patients were investigated by using the following standardized self-reported questionnaires: self-rating idea of suicide scale, Beck hopelessness scale, demoralization scale-Mandarin version, and patient health questionnaire depression scale-9. The mediation hypothesis was tested with a serial multiple mediation model (PROCESS model 6). An exploratory graph analysis was performed to detect the correlations among the dimensions of the mental conditions measured by these instruments. RESULTS: Bootstrap analyzes indicate that there were direct and indirect effects of hopelessness on suicidal ideation mediated solely by demoralization (B = 2.3074, SE = 0.1724, P < .001) or by demoralization together with depression (B = 0.1605, SE = 0.0303, 95% confidence interval [CI] = 0.1102 to 0.2303). The mediation of depression alone in the relationship between hopelessness and suicidal ideation was insignificant (B = 0.1541, SE = 0.0519, 95% CI = -0.0565 to 0.0715). The exploratory graph analysis suggests that the strongest edge of dimensions between demoralization and suicidal ideation was desperation-disheartenment (0.62). CONCLUSIONS: The results of the study support the hypothesis that demoralization and depression mediate between hopelessness and suicidal ideation. The early identification of and interventions for hopelessness, demoralization, and depression may prevent cancer patients from developing suicidal ideation.

Exploring the factors affecting musculoskeletal disorders risk among hospital nurses.

BACKGROUND: Musculoskeletal disorder (MSD) is currently recognized as one of the most common occupational injuries for which nursing personnel in the medical service industry have been identified as a high-risk group. In this study, we explore the prevalence of MSD in various body parts as well as their risk factors among hospital nurses. METHODS: A cross-sectional descriptive design with stratified cluster sampling was used to collect data from 1,803 nurses. The survey included a demographic questionnaire, and Nordic Musculoskeletal Questionnaire. RESULTS: The results showed that the greatest prevalence of MSD symptoms by body regions were in the right shoulder (85.8%), the left shoulder (80.9%), the neck (62.4%), the right wrist (62.2%) and the lower back (60.4%). Risk factors for shoulder discomfort includes department type, exercise habits, and age (p < .05). Risk factors for neck discomfort includes seniority in the current unit, "job title, and "history of MDS (p < .05). Risk factors for upper back discomfort includes age and seniority in the current unit (p < .05). Risk factors for lower back discomfort including seniority in the current unit, department type, and number of days worked per week (p < .05). CONCLUSIONS: The results of this study can serve as a reference for nursing administration managers and decision-makers for reducing musculoskeletal discomfort among nurses and thereby achieving superior quality in clinical care.

A preliminary study of the effectiveness of cancer communication skills training for interdisciplinary staff.

BACKGROUND: Studies have emphasized that the disclosure of a diagnosis and prognosis is the doctor's responsibility, but little attention has been given to the importance of interdisciplinary cooperation. OBJECTIVE: Therefore, this study examined and compared the effectiveness of cancer communication skills training (CST) for doctors and interdisciplinary staff in Taiwan. METHODS: This study utilized a quasi-experimental design. The participants were 124 oncology professionals who participated in cancer CST. These 124 professionals included a group of 65 doctors and a group of 59 interdisciplinary professionals, both of which received the same CST. After the participants have received CST, the changes in their disease disclosure skills were evaluated. RESULTS: Significant pretest-posttest differences were observed in the overall truth-telling scores for both groups (doctors: t = 6.94, P < 0.001; interdisciplinary professionals: t = 7.71, P < 0.001) and in different constructs. However, in many items, the doctors demonstrated no progress after receiving the training (P > 0.05), whereas the interdisciplinary professionals demonstrated significant progress (P < 0.05). In particular, the doctors' scores for 'disclosing information in a monotonous tone' showed significant retrogression (P < 0.05). There were no significant differences in the overall truth-telling scores of the two groups with regard to pre- and post-CST (P > 0.05 and P > 0.05, respectively), and there were also no significant differences in the four sub-scales' scores. CONCLUSION: The CST for interdisciplinary professionals improved their cooperation and communication skills.

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.

Preference of cancer patients and family members regarding delivery of bad news and differences in clinical practice among medical staff.

OBJECTIVES: To study the preferences of cancer patients and their families in way of being informed of their condition and, by comparing their preferences with the medical staff's clinical practices, explore the factors underlying the latter's preferences. METHODS: A survey was conducted with 216 cancer patients, 242 families, and 176 clinical staff members with the Medical Status Communication questionnaire (Simplified Chinese edition). RESULTS: The clinical staff scored lower than the cancer patients and their families in terms of the total score, way of communication, emotional support, and additional information (F = 16.134, p < .001; F = 28.604, p < .001; F = 13.839, p < .001; F = 16.745, p < .001). Factors underlying the medical staff's clinical practices included, as revealed by the multiple linear regression analysis, gender (p = .03), and willingness to improve the way of communication about cancer (p = .006). CONCLUSIONS: A gap existed between the medical staff's clinical practice and the preferences of the cancer patients and their families. The medical staff should receive adequate training in cancer communication skills and techniques for improvement in this respect. When designing training for skills in delivering bad news to cancer patients, the well-being of cancer patients and their families must be thoroughly considered, and patient demands for information should be satisfied in the context of the information explosion of the current age.

Quetiapine ameliorates collagen-induced arthritis in mice via the suppression of the AKT and ERK signaling pathways.

OBJECTIVE AND DESIGN: To investigate the amelioration effects of quetiapine on rheumatoid arthritis with RAW 264.7 macrophage and collagen-induced arthritis (CIA) DBA/1J mouse model. SUBJECTS: RAW 264.7 macrophage and DBA/1J mice. TREATMENT: Lipopolysaccharide and collagen. METHODS: RAW 264.7 macrophages stimulated by lipopolysaccharide (LPS) followed by quetiapine treatments were investigated. Activations of CD80 and CD86 were analyzed by flow cytometry. Pro-inflammatory cytokines such as IL-6, TNF-α and IL-1ß were analyzed by ELISA. Proteins involved in signaling pathways related to the formation of rheumatoid arthritis were assayed by Western blotting. Therapeutic efficacy of quetiapine in CIA mouse model was also assayed. 18F-FDG/micro-PET was used to monitor the inflammation status in the joints, and the severity of bone erosion was evaluated with micro-CT and H&E staining. RESULTS: The inhibition of pro-inflammatory cytokines by quetiapine was found through the ERK and AKT phosphorylation and subsequent NF-κB and CREB signaling pathways. Pro-inflammatory cytokines such as IL-17, IL-6 and IL-1ß were decreased, while immunosuppressive factors such as TGF-ß and IL-10 were increased in CIA mice treated with quetiapine. Notably, no uptake of 18F-FDG and bone erosion was found with micro-PET images on days 32 and 43 in the quetiapine-treated and normal control groups. However, significant uptake of 18F-FDG could be observed in the CIA group during the same time course. Similar results were further verified with ex vivo autoradiography. CONCLUSION: Taken together, these results suggest that quetiapine is a potential anti-inflammatory drug, and may be used as an adjuvant for the treatment of rheumatoid arthritis.

Truth telling in Taiwanese cancer care: patients' and families' preferences and their experiences of doctors' practices.

OBJECTIVE: Despite the significant role played by cancer patients' families in medical decision-making in Asian countries, inconsistencies have hitherto not been evaluated between patients' and families' preferences and doctors' actual practices with regard to cancer truth telling. METHODS: For this quantitative comparative study of cancer patients' and families' truth-telling preferences and their experiences of doctors' practices, 532 patients, 551 family members, and 127 doctors (N = 1 210) were enrolled from five hospitals across Taiwan over 2 years. Truth telling was assessed using the Taiwanese version of a modified Japanese truth-telling scale. RESULTS: Patients' truth-telling preferences and their experiences of doctors' truth-telling practices differed significantly in scores on the overall truth-telling scale and each subscale, including method of disclosure, emotional support, additional information, and setting (P < .001). Similar findings were obtained for families' preferences and doctors' actual practices (P < .001). Patients' and families' truth-telling preference scores were higher than doctors' actual practice scores. Multiple regression analysis revealed a dose-dependent effect of doctors' monthly truth-telling frequency on their truth-telling preferences, but this effect was only borderline significant (P = .08). This multiple regression model explained 30% of the total variance in doctors' truth-telling preferences (F = 1.38, P = .22). CONCLUSIONS: Taiwanese medical educational policies need to be revised to better equip doctors to practice truth telling in accordance with the preferences of cancer patients and families. Communication skills training should be prioritized for doctors who refrain from truth telling in actual practice.

Self-harm and its association with internet addiction and internet exposure to suicidal thought in adolescents.

BACKGROUND/PURPOSE: Self-harm (SH) is a risk factor for suicide. We aimed to determine whether internet addiction and internet exposure to confided suicidal ideation are associated with SH in adolescents. METHODS: This study was a cross-sectional survey of students who self-completed a series of online questionnaires including a sociodemographic information questionnaire, questionnaire for suicidality and SH, Chen Internet Addiction Scale (CIAS), Patient Health Questionnaire (PHQ-9), multi-dimensional support scale (MDSS), Rosenberg self-esteem scale (RSES), Alcohol Use Disorder Identification Test-Consumption (AUDIT-C), and questionnaire for substance abuse. RESULTS: A total of 2479 students completed the questionnaires (response rate = 62.1%). They had a mean age of 15.44 years (range 14-19 years; standard deviation 0.61), and were mostly female (n = 1494; 60.3%). The prevalence of SH within the previous year was 10.1% (n = 250). Among the participants, 17.1% had internet addiction (n = 425) and 3.3% had been exposed to suicidal content on the internet (n = 82). In the hierarchical logistic regression analysis, internet addiction and internet exposure to suicidal thoughts were both significantly related to an increased risk of SH, after controlling for gender, family factors, exposure to suicidal thoughts in the real life, depression, alcohol/tobacco use, concurrent suicidality, and perceived social support. However, the association between internet addiction and SH weakened after adjusting for the level of self-esteem, while internet exposure to suicidal thoughts remained significantly related to an increased risk of SH (odds ratio = 1.96; 95% confidence interval: 1.06-3.64). CONCLUSION: Online experiences are associated with SH in adolescents. Preventive strategies may include education to increase social awareness, to identify the youths most at risk, and to provide prompt help.

Resting respiratory sinus arrhythmia is related to longer hospitalization in mood-disordered repetitive suicide attempters.

OBJECTIVES: Our aims were (1) to measure respiratory sinus arrhythmia (RSA), a high-frequency spectrum component of heart rate variability (HRV) in mood-disordered suicide attempters and (2) to investigate the relationship of RSA to symptoms and length of hospitalization. METHODS: Forty-nine female repetitive-suicide attempters with depressive disorder or bipolar disorder were recruited in a general hospital setting. Manic or psychotic patients were excluded. Resting RSA values were calculated from electrocardiogram data, and severity of clinical presentation shortly after admission and length of hospital stay were assessed. RESULTS: RSA was positively associated with a higher Beck Scale for Suicidal Ideation score (r = 0.33 P = 0.019). Stepwise multiple regression analysis showed a significant correlation between RSA and hospitalization length after adjusting other variables (beta coefficient = 3.00; P = 0.030). Patients with a higher resting RSA had more prolonged hospitalizations (hospitalization beyond 30 days) after controlling for other variables (odds ratio = 5.08, P = 0.017). CONCLUSIONS: Interaction between the environment and the autonomic nervous system is complex. Further and more comprehensive research is needed.

Posttraumatic growth and demoralization after cancer: The effects of patients' meaning-making.

OBJECTIVE: It is common for patients to experience positive and negative psychological changes (e.g., posttraumatic growth or demoralization) after being diagnosed with cancer. Although demoralization and posttraumatic growth are both related to meaning-making, little attention has been paid to the associations among these concepts. The current study investigated the relationship between demoralization, posttraumatic growth, and meaning-making (focusing on sense-making and benefit-finding during the experience of illness) in cancer patients. METHOD: Some 200 cancer patients (with lung cancer, lymphoma, or leukemia) at the MacKay Memorial Hospital in New Taipei completed the Demoralization Scale-Mandarin Version (DS-MV), the Chinese Posttraumatic Growth Inventory (CPTGI), and a self-designed questionnaire for assessing sense-making and benefit-finding. RESULTS: Demoralization was negatively correlated with posttraumatic growth, sense-making, benefit-finding, and time-since-diagnosis. Multiple regression analysis showed that meaning-making had different effects on demoralization and posttraumatic growth. The interactions of sense-making with either benefit-finding or time-since-diagnosis significantly predicted demoralization. Individuals with relatively higher sense-making and benefit-finding or shorter time-since-diagnosis experienced less demoralization. SIGNIFICANCE OF RESULTS: The suffering of cancer may turn on the psychological process of demoralization, posttraumatic growth, and meaning-making in patients. Cancer patients who evidenced higher posttraumatic growth experienced less demoralization. Trying to identify positive changes in the experience of cancer may be a powerful way to increase posttraumatic growth. As time goes by, patients experienced less demoralization. Facilitating sense-making can have similar effects. Cancer patients with less benefit-finding experience higher demoralization, but sense-making buffers this effect.

A correlational study of suicidal ideation with psychological distress, depression, and demoralization in patients with cancer.

PURPOSE: This study aims to study the effects of depression and demoralization on suicidal ideation and to determine the feasibility of the Distress Thermometer as a screening tool for patients with cancer who experience depression and demoralization, and thus to establish a model screening process for suicide prevention. METHODS: Purposive sampling was used to invite inpatients and outpatients with lung cancer, leukemia, and lymphoma. Two hundred participants completed the questionnaire, which included the Distress Thermometer (DT), Patient Health Questionnaire-9 (PHQ-9), Demoralization Scale-Mandarin Version (DS-MV), and Beck Scale for Suicide Ideation. All data obtained were analyzed using SPSS 18.0 and SAS 9.3. RESULTS: Tobit regression analysis showed that demoralization influenced suicidal ideation more than depression did (t = 2.84, p < 0.01). When PHQ-9 ≥ 10 and DS-MV ≥42 were used as criteria for the DT, receiver operating characteristic analysis revealed that the AUC values were 0.77-0.79, with optimal cutoff points for both of DT ≥5; sensitivity 76.9 and 80.6 %, respectively; and specificity of 73.9 and 72.2 %, respectively. CONCLUSIONS: Demoralization had more influence on suicidal ideation than depression did. Therefore, attention should be paid to highly demoralized patients with cancer or high demoralization comorbid with depression for the purposes of suicide evaluation and prevention. The DT scale (with a cutoff of ≥5 points) has discriminative ability as a screening tool for demoralization or depression and can also be used in clinical settings for the preliminary screening of patients with cancer and high suicide risk.

The characteristics, management, and aftercare of patients with suicide attempts who attended the emergency department of a general hospital in northern Taiwan.

BACKGROUND: Suicide is a serious public health problem worldwide. The emergency department (ED) is often the first place of contact with medical and mental health care for suicidal patients. This study aimed to determine the characteristics, management, and aftercare of patients who attempted suicide and then were taken to the ED of a general hospital in Taipei, Taiwan. METHODS: Our study was a cross-sectional retrospective study that consecutively recruited patients with suicide attempts attended to the ED of a general hospital from June 2004 to May 2005. The patients' medical information and records pertaining to their emergency visit were subsequently reviewed. RESULTS: Overall, 481 persons were recruited into our study. The male:female ratio of total surviving attempters was approximately 1:4 and the average age was 33.6 [standard deviation (SD) 12.3] years. The most frequently observed general characteristics from which participants suffered were mental illness (73.1%) and interpersonal problems (76.1%). Nearly all patients (91.7%) received ED on-site psychosocial assessments from social workers (SWs) and psychiatrists in 84.2% and 53.4% of cases, respectively. Less than half of patients (45.1%) were referred to psychiatric outpatient aftercare, and only 26.1% contacted the psychiatric outpatient clinics after discharge from the ED. The stated reasons for psychiatric outpatient referral were associated with interpersonal problems, current psychiatric illness, the ED on-site psychiatrist consultation, and admission to medical, surgical, or psychiatric wards. However, individuals with interpersonal problems, previous psychiatric intervention, and ED on-site psychiatrist consultation were significantly more likely to attend outpatient psychiatric aftercare. CONCLUSION: Individuals who harmed themselves had a high rate of psychiatric morbidity and interpersonal problems. However, their adherence to psychiatric outpatient aftercare was low. Improved identification of the needs of patients with suicidal tendencies who did not attend outpatient services will have implications for future services provided to this patient population, and will better enable medical personnel to most effectively assist in suicide attempt interventions.

Effectiveness of Japanese SHARE model in improving Taiwanese healthcare personnel's preference for cancer truth telling.

BACKGROUND: Communication skills training (CST) based on the Japanese SHARE model of family-centered truth telling in Asian countries has been adopted in Taiwan. However, its effectiveness in Taiwan has only been preliminarily verified. This study aimed to test the effect of SHARE model-centered CST on Taiwanese healthcare providers' truth-telling preference, to determine the effect size, and to compare the effect of 1-day and 2-day CST programs on participants' truth-telling preference. METHOD: For this one-group, pretest-posttest study, 10 CST programs were conducted from August 2010 to November 2011 under certified facilitators and with standard patients. Participants (257 healthcare personnel from northern, central, southern, and eastern Taiwan) chose the 1-day (n = 94) or 2-day (n = 163) CST program as convenient. Participants' self-reported truth-telling preference was measured before and immediately after CST programs, with CST program assessment afterward. RESULTS: The CST programs significantly improved healthcare personnel's truth-telling preference (mean pretest and posttest scores ± standard deviation (SD): 263.8 ± 27.0 vs. 281.8 ± 22.9, p < 0.001). The CST programs effected a significant, large (d = 0.91) improvement in overall truth-telling preference and significantly improved method of disclosure, emotional support, and additional information (p < 0.001). Participation in 1-day or 2-day CST programs did not significantly affect participants' truth-telling preference (p > 0.05) except for the setting subscale. Most participants were satisfied with the CST programs (93.8%) and were willing to recommend them to colleagues (98.5%). CONCLUSIONS: The SHARE model-centered CST programs significantly improved Taiwanese healthcare personnel's truth-telling preference. Future studies should objectively assess participants' truth-telling preference, for example, by cancer patients, their families, and other medical team personnel and at longer times after CST programs.

Acute effects of three club drugs on the striatum of rats: evaluation by quantitative autoradiography with [18F]FDOPA.

In this work, we used quantitative autoradiography to study the acute effect of cocaine, methamphetamine, and ketamine on the uptake of [(18)F]FDOPA in the striatum of rats. Drugs were treated 0.5 h before (pre-treated), and 1.5 h after (post-treated) [(18)F]FDOPA injections, rats were then sacrificed at 2 h post [(18)F]FDOPA injections to determine the striatum/frontal cortex binding ratios in the striatum. The ratios were lower in the post-treated groups than those of the pre-treated groups, suggesting a net effect of inhibition of trapping of the tracer. The order of uptake inhibition is: ketamine>methamphetamine>cocaine.

Truth telling in medical practice: students' opinions versus their observations of attending physicians' clinical practice.

OBJECTIVE: Truth telling or transmitting bad news is a problem that all doctors must frequently face. The purpose of this cross-sectional study was to investigate if medical students' opinions of truth telling differed from their observations of attending physicians' actual clinical practice. METHODS: The subjects were 275 medical clerks/interns at a medical center in northern Taiwan. Data were collected on medical students' opinions of truth telling, their observations of physicians' clinical practice, students' level of satisfaction with truth telling practiced by attending physicians, and cancer patients' distress level when they were told the truth. RESULTS: Students' truth-telling awareness was significantly higher than the clinical truth-telling practice of attending physicians (p<0.001), and the means for these parameters had a moderate difference, especially in three aspects: method, emotional support, and providing additional information (p<0.001). Regardless of this difference, students were satisfied with the truth telling of attending physicians (mean ± SD=7.33 ± 1.74). However, our data also show that when cancer patients were informed of bad news, they all experienced medium to above average distress (5.93 ± 2.19). CONCLUSIONS: To develop the ability to tell the truth well, one must receive regular training in communication skills, including experienced attending physicians. This study found a significant difference between medical students' opinions on truth telling and attending physicians' actual clinical practice. More research is needed to objectively assess physicians' truth telling in clinical practice and to study the factors affecting the method of truth telling used by attending physicians in clinical practice.

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.

Mirtazapine inhibits tumor growth via immune response and serotonergic system.

To study the tumor inhibition effect of mirtazapine, a drug for patients with depression, CT26/luc colon carcinoma-bearing animal model was used. BALB/c mice were randomly divided into six groups: two groups without tumors, i.e. wild-type (no drug) and drug (mirtazapine), and four groups with tumors, i.e. never (no drug), always (pre-drug, i.e. drug treatment before tumor inoculation and throughout the experiment), concurrent (simultaneously tumor inoculation and drug treatment throughout the experiment), and after (post-drug, i.e. drug treatment after tumor inoculation and throughout the experiment). The "psychiatric" conditions of mice were observed from the immobility time with tail suspension and spontaneous motor activity post tumor inoculation. Significant increase of serum interleukin-12 (sIL-12) and the inhibition of tumor growth were found in mirtazapine-treated mice (always, concurrent, and after) as compared with that of never. In addition, interferon-γ level and immunocompetent infiltrating CD4+/CD8+ T cells in the tumors of mirtazapine-treated, tumor-bearing mice were significantly higher as compared with that of never. Tumor necrosis factor-α (TNF-α) expressions, on the contrary, are decreased in the mirtazapine-treated, tumor-bearing mice as compared with that of never. Ex vivo autoradiography with [(123)I]ADAM, a radiopharmaceutical for serotonin transporter, also confirms the similar results. Notably, better survival rates and intervals were also found in mirtazapine-treated mice. These findings, however, were not observed in the immunodeficient mice. Our results suggest that tumor growth inhibition by mirtazapine in CT26/luc colon carcinoma-bearing mice may be due to the alteration of the tumor microenvironment, which involves the activation of the immune response and the recovery of serotonin level.
