Beneficial effects of omega-3 fatty acid supplementation in schizophrenia: possible mechanisms.

BACKGROUND: Schizophrenia is a serious long-term psychotic disorder marked by positive and negative symptoms, severe behavioral problems and cognitive function deficits. The cause of this disorder is not completely clear, but is suggested to be multifactorial, involving both inherited and environmental factors. Since human brain regulates all behaviour, studies have focused on identifying changes in neurobiology and biochemistry of brain in schizophrenia. Brain is the most lipid rich organ (approximately 50% of brain dry weight). Total brain lipids is constituted of more than 60% of phospholipids, in which docosahexaenoic acid (DHA, 22:6n-3) is the most abundant (more than 40%) polyunsaturated fatty acid (PUFA) in brain membrane phospholipids. Results from numerous studies have shown significant decreases of PUFAs, in particular, DHA in peripheral blood (plasma and erythrocyte membranes) as well as brain of schizophrenia patients at different developmental phases of the disorder. PUFA deficiency has been associated to psychotic symptoms and cognitive deficits in schizophrenia. These findings have led to a number of clinical trials examining whether dietary omega-3 fatty acid supplementation could improve the course of illness in patients with schizophrenia. Results are inconsistent. Some report beneficial whereas others show not effective. The discrepancy can be attributed to the heterogeneity of patient population. METHODS: In this review, results from recent experimental and clinical studies, which focus on illustrating the role of PUFAs in the development of schizophrenia were examined. The rationale why omega-3 supplementation was beneficial on symptoms (presented by subscales of the positive and negative symptom scale (PANSS), and cognitive functions in certain patients but not others was reviewed. The potential mechanisms underlying the beneficial effects were discussed. RESULTS: Omega-3 fatty acid supplementation reduced the conversion rate to psychosis and improved both positive and negative symptoms and global functions in adolescents at ultra-high risk for psychosis. Omega-3 fatty acid supplementation could also improve negative symptoms and global functions in the first-episode patients with schizophrenia, but improve mainly total or general PANSS subscales in chronic patients. Patients with low PUFA (particularly DHA) baseline in blood were more responsive to the omega-3 fatty acid intervention. CONCLUSION: Omega-3 supplementation is more effective in reducing psychotic symptom severity in young adults or adolescents in the prodromal phase of schizophrenia who have low omega-3 baseline. Omega-3 supplementation was more effective in patients with low PUFA baseline. It suggests that patients with predefined lipid levels might benefit from lipid treatments, but more controlled clinical trials are warranted.

Increased circulating endothelial progenitor cells and improved short-term outcomes in acute non-cardioembolic stroke after hyperbaric oxygen therapy.

BACKGROUND: Acute ischemic stroke is a leading cause of mortality and long-term disability, and profiles of endothelial progenitor cells (EPCs) reflect the degree of endothelial impairment. This study tested the hypothesis that hyperbaric oxygen therapy (HBOT) both improves the clinical short-term outcomes and increases the number of circulating EPCs and antioxidant capacity. METHODS: The numbers of circulating EPCs [CD133+/CD34+ (%), KDR+/CD34+ (%)], biomarkers for oxidative stress (thiols and thiobarbituric acid-reactive substances), and clinical scores (National Institutes of Health Stroke Scale [NIHSS], Barthel index [BI], and modified Rankin Scale [MRS]) were prospectively evaluated in 25 patients with acute non-cardioembolic stroke under HBOT at two time points (pre- and post-HBOT). The biomarkers and clinical scores were compared with those of 25 age- and sex-matched disease controls. RESULTS: The numbers of KDR+/CD34+ (%) in the HBOT group following HBOT increased significantly, whereas the numbers of CD133+/CD34+ (%) also showed a tendency to increase without statistical significance. The mean high-sensitivity C-reactive protein levels showed significant decrease post-HBOT follow-up in the HBOT group. The changes in KDR+/CD34+EPC (%) numbers were positively correlated with changes in clinical outcomes scores (BI, NIHSS, and MRS) in the HBOT group. CONCLUSIONS: Based on the results of our study, HBOT can both improve short-term clinical outcomes and increase the number of circulating EPCs in patients with acute non-cardioembolic stroke.

Adjunctive Hyperbaric Oxygen Therapy for Healing of Chronic Diabetic Foot Ulcers: A Randomized Controlled Trial.

PURPOSE: The purpose of this study was to compare the effect of standard wound care with adjunctive hyperbaric oxygen therapy (HBOT) to standard wound care alone on wound healing, markers of inflammation, glycemic control, amputation rate, survival rate of tissue, and health-related quality of life in patients with diabetic foot ulcers (DFUs). DESIGN: Prospective, randomized, open-label, controlled study. SUBJECTS AND SETTING: The sample comprised 38 patients with nonhealing DFUs who were deemed poor candidates for vascular surgery. Subjects were randomly allocated to an experimental group (standard care plus HBOT, n = 20) or a control group (standard care alone, n = 18). The study setting was a medical center in Kaohsiung City, Taiwan. METHODS: Hyperbaric oxygen therapy was administered in a hyperbaric chamber under 2.5 absolute atmospheric pressure for 120 minutes; subjects were treated 5 days a week for 4 consecutive weeks. Both groups received standard wound care including debridement of necrotic tissue, topical therapy for Wagner grade 2 DFUs, dietary control and pharmacotherapy to maintain optimal blood glucose levels. Wound physiological indices were measured and blood tests (eg, markers of inflammation) were undertaken. Health-related quality of life was measured using the Medical Outcomes Study 36-Item Short Form. RESULTS: Complete DFU closure was achieved in 5 patients (25%) in the HBOT group (n = 20) versus 1 participant (5.5%) in the routine care group (n = 18) (P = .001). The amputation rate was 5% for the HBOT group and 11% for the routine care group (χ = 15.204, P = .010). The HBOT group showed statistically significant improvements in inflammation index, blood flow, and health-related quality of life from pretreatment to 2 weeks after the last therapy ended (P < .05). Hemoglobin A1c was significantly lower in the HBOT group following treatment (P < .05) but not in the routine care group. CONCLUSIONS: Adjunctive HBOT improved wound healing in persons with DFU. Therapy also reduced the risk of amputation of the affected limb. We assert that at least 20 HBOT sessions are required to be effective.

Apolipoprotein J, a glucose-upregulated molecular chaperone, stabilizes core and NS5A to promote infectious hepatitis C virus virion production.

BACKGROUND & AIMS: Hepatitis C virus (HCV) infection leads to glucose abnormality. HCV depends on lipid droplets (LDs) and very-low density lipoproteins for assembly/releasing; however, the components and locations for this process remain unidentified. Apolipoprotein J (ApoJ), upregulated by glucose, functions as Golgi chaperone of secreted proteins and resides abundantly in very-low density lipoproteins. This study investigates the interplay between glucose, ApoJ and HCV virion production. METHODS: The effects of high glucose on ApoJ expression and HCV production were evaluated with cultivated HuH7.5, primary human hepatocytes, and in treatment naive chronic hepatitis C patients. How ApoJ affects HCV lifecycle was assessed using siRNA knockdown strategy in JFH1 infected and subgenomic replicon cells. The interactions and locations of ApoJ with viral and host components were examined by immunoprecipitation, immunofluorescence and subcellular fractionation experiments. RESULTS: HCV infection increased ApoJ expression, which in parallel with HCV infectivity was additionally elevated with high glucose treatment. Serum ApoJ correlated positively with fasting blood glucose concentration and HCV-RNA titre in patients. ApoJ silencing reduced intracellular and extracellular HCV infectivity and extracellular HCV-RNA, but accumulated intracellular HCV-RNA in HCV-infected cells. ApoJ interacted with HCV core and NS5A and stabilized the dual protein complex. HCV infection dispersed cytoplasmic ApoJ from the compact zones of the Golgi to encircle LDs, where co-localization of the core, NS5A, HCV-RNA, subcellular markers for LDs, endoplasmic reticulum (ER), Golgi, and membrane contact sites occurred. CONCLUSIONS: ApoJ facilitates infectious HCV particle production via stabilization of core/NS5A, which might surround LDs at the ER-Golgi membrane contact site.

Routine depression screening and diagnosing strategy for cancer inpatients.

BACKGROUND: Clinical practice guidelines frequently recommend systematic screening for depression in cancer patients to improve recognition and prompt appropriate management. We aimed to screen major depressive disorder (MDD) in cancer inpatients using a structured tool and explore its applicability. METHODS: Cancer inpatients were routinely screened by nurses using the Taiwanese Depression Questionnaire (TDQ), and for those screened positive, this was followed by a non-mandated referral to a psychiatrist for clinical evaluation and diagnosis. Patients who completed this two-stage procedure comprised the analysis sample. RESULTS: Routine screening of 8800 patients in a period of 27 months yielded 1087 (26.9%) positive first-time screens. Of them, 298 (27.4%) completed the psychiatric consultation. Depressive disorders were diagnosed in 185 patients (62.1%), mainly adjustment disorder (23.8%) and MDD (21.5%). The estimated prevalence of MDD was 21.5%. Area under the curve was 0.72, a result produced by the receiver operating characteristic curve of the TDQ scores relative to the clinical psychiatric diagnoses of MDD. A TDQ cutoff score of ≧26 provided an optimal diagnostic accuracy for MDD. CONCLUSIONS: This two-stage depression screening and diagnosing strategy is practical for improving recognition of MDD and other depressive disorders in cancer patients and could be routinely applied, rather than selectively, in a comprehensive cancer care system.

Adult patients with schizophrenia using violence towards their parents: a phenomenological study of views and experiences of violence in parent-child dyads.

AIMS: To describe the lived experiences of aggression and violence among patients with schizophrenia and their victimized biological parent as the major caregiver being aggressed by their child (parent-adult-child dyads), and to gain an understanding of the precipitating factors influencing violence. BACKGROUND: Child-to-parent violence, particularly in the mentally ill adult child, is arguably the most stressful and under-researched issue of family violence. Violence in patients with mental illness is most frequently targeted at family members, and most often takes place at home. Both patients and their parents' experiences of violence are relatively unexplored. DESIGN: Qualitative study design. METHODS: Data were collected using individual in-depth interviews between August 2010-August 2011 in Taiwan. Purposive sample of 14 hospitalized patients with schizophrenia who had aggression and violence in the past year directed towards their biological parent of either gender. FINDINGS: Five main themes were identified: violence occurring beyond control in a particular situation translated into parent and patient's possible endangerment, the repetitive nature of violence, distress, ineffective communication, and management of violence and help-seeking. Repetitive violent episodes and tension made both the parent and patient feel uncontrollable. Parents had a perceived fear of adverse consequences such as being punished by receiving more retribution and they also had concerns related to their parental responsibility. CONCLUSIONS: Health professionals should be aware of the complexity of phenomena and the interplay of factors inducing violence. A comprehensive dyadic parent-child intervention is suggested for violence prevention.

Improving quality-of-life outcomes for patients with cancer through mediating effects of depressive symptoms and functional status: a three-path mediation model.

AIMS AND OBJECTIVES: To test a hypothetical three-path mediation model evaluating the effects of functional status and depressive symptoms on the relationship between fatigue and quality of life in patients with cancer on the basis of the Theory of Unpleasant Symptoms. BACKGROUND: Patients with cancer often experience two or more concurrent, interrelated, mutually influential symptoms. Multiple unpleasant symptoms that have been proposed as mediating variables affecting quality of life in a model proposed in recent cancer studies are scanty. DESIGN: This study was a cross-sectional, descriptive, correlational design. METHODS: Three hundred and twenty-six patients with cancer from oncology clinics were recruited in Taiwan between 2010-2011. Mediation models were tested and confirmed by applying structural modelling using Analysis of Moment Structures and the joint significance test. RESULTS: Fatigue affects patient quality of life directly or indirectly through functional status and depressive symptoms. These two mediating variables exhibited direct effects on quality of life. A path analysis approach revealed that 47·28 and 67·70% of the total effects of functional status and depressive symptoms, respectively, on the quality-of-life mediation models are attributable to 29·6 and 44·7% of the total effects between fatigue and quality of life, which mediated through two mediators, respectively. CONCLUSION: Quality of life may be enhanced by simultaneously improving physiological and psychological factors. RELEVANCE TO CLINICAL PRACTICE: An understanding of mediating effects is valuable in nursing care of patients with cancer, particularly in the early phase of treatment or in newly diagnosed stages I-III or recently treated patients with cancer in different disease stages.

The dyslipidemia-associated SNP on the APOA1/C3/A5 gene cluster predicts post-surgery poor outcome in Taiwanese breast cancer patients: a 10-year follow-up study.

BACKGROUND: Post-surgery therapies are given to early-stage breast cancer patients due to the possibility of residual micrometastasis, and optimized by clincopathological parameters such as tumor stage, and hormone receptor/lymph node status. However, current efficacy of post-surgery therapies is unsatisfactory, and may be varied according to unidentified patient genetic factors. Increases of breast cancer occurrence and recurrence have been associated with dyslipidemia, which can attribute to other known risk factors of breast cancer including obesity, diabetes and metabolic syndrome. Thus we reasoned that dyslipidemia-associated nucleotide polymorphisms (SNPs) on the APOA1/C3/A5 gene cluster may predict breast cancer risk and tumor progression. METHODS: We analyzed the distribution of 5 selected APOA1/C3/A5 SNPs in recruited Taiwanese breast cancer patients (n=223) and healthy controls (n=162). The association of SNP (APOA1 rs670) showing correlation with breast cancer with baseline and follow-up parameters was further examined. RESULTS: APOA1 rs670 A allele carriage was higher in breast cancer patients than controls (59.64% vs. 48.77%, p=0.038). The rs670 A allele carrying patients showed less favorable baseline phenotype with positive lymph nodes (G/A: OR=3.32, 95% CI=1.77-6.20, p<0.001; A/A: OR=2.58, 95% CI=1.05-6.32, p=0.039) and negative hormone receptor expression (A/A: OR=4.85, 95%CI=1.83-12.83, p=0.001) in comparison to G/G carriers. Moreover, rs670 A/A carrying patients had higher risks in both tumor recurrence (HR=3.12, 95% CI=1.29-7.56, p=0.012) and mortality (HR=4.36, 95% CI=1.52-12.47, p=0.006) than patients with no A alleles after adjustments for associated baseline parameters. Furthermore, the prognostic effect of rs670 A/A carriage was most evident in lymph node-negative patients, conferring to the highest risks of recurrence (HR=4.98, 95% CI=1.40-17.70, p=0.013) and mortality (HR=9.87, 95%CI=1.60-60.81, p=0.014) than patients with no A alleles. CONCLUSIONS: APOA1 rs670 A/A carriage showed poor post-surgery prognosis in Taiwanese lymph node-negative breast cancer patients, whose prognosis were considered better and adjuvant treatment might be less stringent according to currently available assessment protocols. Our findings suggest that APOA1 rs670 indicate a post-surgery risk of breast cancer disease progression, and that carriers of this SNP may benefit from more advanced disease monitoring and therapy regimens than the current regular standards. Furthermore, control of lipid homeostasis might protect APOA1 rs670 minor allele carriers from breast cancer occurrence and progression.

Lived Experience of Violence Perpetrated by Treated Patients and Their Visitors in Intensive Care Units: A Qualitative Study of Nurses.

BACKGROUND: Patient and visitor violence (PVV) is a widespread problem for health professionals. Nurses working in intensive care units (ICUs) face a relatively high risk of experiencing PVV, which significantly impacts both the health of nurses and the institution as a whole. The subjective perceptions of ICU nurses regarding PVV are inadequately explored in the literature. PURPOSE: The purpose of this study was to explore the perspectives, experiences, and perceptions of PVV in ICU nurses and to better understand the precipitating factors of violence. METHODS: A phenomenological qualitative design and purposive sampling were used. A semistructured interview guide was used to conduct in-depth interviews with 12 ICU nurses with PVV experiences. Giorgi's method of analysis was used to discover and identify the essential categories of experience. RESULTS: Five main experience categories were identified: family and patient factors as flashpoints, managing suppressed emotions by weathering the emotional storm, spiritual awakening after violence, and strategies for surviving further violence. The participants' experiences with PVV included a range of caring and mental health difficulties. In ICU settings, patient progress is often unpredictable, resulting in discrepancies between patient/family expectations and reality. Because feelings of frustration and powerlessness can eventually cause exhaustion in ICU nurses, implementing effective emotional management, stress adjustment, psychological counseling, team support, and violence intervention programs are crucial. CONCLUSIONS/IMPLICATIONS FOR PRACTICE: This study provides new information on the process by which nurses can progress from inner trauma to self-recovery, moving from a negative affectivity disposition to a better understanding of threat appraisals and coping response options. Nurses should increase their awareness of the complexity of the phenomenon and of the interplay among the factors underlying PVV. The results of this study suggest that routine confusion and delirium assessments to rule out patients with ICU delirium in ICUs are important to preventing PVV. This study considers some of the implications of the research findings for nursing managers. Interventions, training programs, and/or management action should be used to ensure psychological and mental support is extended to all witnesses of PVV events and not only to those targeted by violence.

Early B blasts acquire a capacity for Ig class switch recombination that is lost as they become plasmablasts.

Rapid production of neutralizing antibody can be critical for limiting the spread of infection. Such early antibody results when B-cell blasts mature directly to plasmablasts without forming germinal centers. These extrafollicular responses can involve Ig class switch recombination (CSR), producing antibody that can readily disseminate through infected tissues. The present study identifies the differentiation stage where CSR occurs in an extrafollicular response induced by 4-hydroxy-3-nitrophenyl acetyl (NP) conjugated to Ficoll (NP-Ficoll). To do this, we took advantage of the antigen dose dependency of CSR in this response. Thus, while both 30 and 1 µg NP-Ficoll induce plasmablasts, only the higher antigen dose induces CSR. Activation-induce cytidine deaminase (AID) is critical for CSR and in keeping with this a proportion of NP-specific B-cell blasts induced by 30 µg NP-Ficoll express AID. None of the B blasts responding to the non-CSR-inducing 1 µg dose of NP-Ficoll express AID. We confirmed that CSR occurs in B blasts by demonstrating the presence of rearranged heavy-chain transcripts in B blasts in the 30 µg response. CSR in this extrafollicular response is confined to B blasts, because NP-specific plasmablasts, identified by expressing CD138 and Blimp-1, no longer express AID and cannot undergo CSR.

An exploratory study of religious involvement as a moderator between anxiety, depressive symptoms and quality of life outcomes of older adults.

AIMS: The aims of this study were to examine the relationships among religion, religious involvement, anxiety, depressive symptoms and quality of life in older adults with psychological problems and whether religious involvement moderated anxiety and depressive symptoms on the outcome of quality of life. Evidence for the mechanism through which religious involvement exerts its moderated effect on anxiety and depressive symptoms was provided. BACKGROUND: Older adults suffering from stress may consequently have anxiety or depressive symptoms and their quality of life is also influenced. The meanings of religious involvement are well documented but less is known about moderating characteristics that determine which older adults with psychological problems are most likely to benefit. DESIGN: A correlational, cross-sectional study. METHODS: The study was conducted in 2007-2008 with a purposive sample of 115 older adults who were 60 years of age or older at a psychiatric centre in Taiwan. Three reliable and valid questionnaires and a demographic sheet were administered. RESULTS: Approximately 75% of older adults had mild to severe anxiety; 76·5% had depressive symptoms; and 67·8% of participants who had depressive symptoms also had comorbid anxiety. Findings indicated that there was a significant moderating effect for religious involvement on the quality of life outcome. Religious involvement significantly moderated anxiety and depressive symptoms on quality of life. Moreover, religious participants had a better quality of life and had lower anxiety and depressive symptoms than non-religious participants. CONCLUSION: Testing for moderating effects provides important information regarding the benefits of religious involvement. The current study reveals that religious participants have lower levels of depressive symptoms and anxiety and better quality of life than non-religious ones. Religious involvement plays a role in buffering the relationship between psychological problems and quality of life. RELEVANCE TO CLINICAL PRACTICE: Nurses can encourage individuals with health problems to participate in religious involvement, which may help individuals to experience a feeling of support and enhance their quality of life.

Efficacy and safety of combination of risperidone and haloperidol with divalproate in patients with acute mania.

OBJECTIVE: The current study evaluated the efficacy and safety of risperidone and haloperidol as an adjunctive agent in combination with divalproate in patients with an episode of acute mania. METHODS: This 6-week randomized, single-blind study was conducted in psychiatric wards of a mental hospital. A total of 41 patients were randomly assigned to the risperidone (risperidone plus divalproate) or haloperidol groups (haloperidol plus divalproate). Efficacy was assessed by changes in symptom rating scales [Young Mania Rating Scale (YMRS), Brief Psychiatric Rating Scale (BPRS), and Clinical Global Impression (CGI) scores]. Safety and tolerability were assessed by monitoring the Extrapyramidal Symptom Rating Scale (ESRS) and Hamilton Rating Scale for depression. RESULTS: Mean doses at baseline, and at weeks 4 and 6 were 3.77, 4.95 and 5.00 mg/day of risperidone and 5.89, 9.95 and 8.58 mg/day of haloperidol, respectively. Risperidone was shown to have significant anti-manic effects which was observed as early as week 1, following start of treatment. The BPRS scores were in favor of risperidone at week 2. Patients receiving risperidone exhibited significant greater global improvement on the CGI, as early as week 2 and over the entire treatment period, than haloperidol after 4 weeks of treatment. The ESRS at endpoint were significantly higher in the haloperidol patients. CONCLUSIONS: Risperidone plus divalproate was more efficacious than haloperidol plus divalproate for treatment of acute mania, and was well tolerated due to its evidence showing rapid anti-manic action, effective and sustained control of manic and psychotic symptoms and a favorable safety and tolerability profile in acute mania.

Effects of Integrated Workplace Violence Management Intervention on Occupational Coping Self-Efficacy, Goal Commitment, Attitudes, and Confidence in Emergency Department Nurses: A Cluster-Randomized Controlled Trial.

Patient and visitor violence (PVV), the most prevalent source of workplace violence, is largely ignored, underreported, and a persistent problem in emergency departments. It is associated with physical injuries, psychological distress, and occupational stress in nurses. A randomized controlled trial was conducted in Taiwan from January to December 2020. This study aimed to test the efficacy of an integrated Workplace Violence Prevention and Management Training Program on PVV in 75 emergency department (ED) nurses from a hospital. Cluster sampling was used because the policy of subdivision strategy was enforced during the COVID-19 pandemic. ED nurses received either the intervention or 1-hour in-service class. Data were collected from questionnaires. Data were analyzed mainly by the repeated measure analysis of variance and generalized estimating equations. The intervention had positive effects on developing stronger goal commitment, improving occupational coping self-efficacy, increasing confidence in ability to deal with violent situations, and modifying attitudes toward the causes and management of PVV in ED nurses (p < 0.05). The marginal R2 of the generalized estimating equation model for goal commitment, occupational coping self-efficacy, confidence, attitudes toward aggression in ED and aggressive behavior variables was high as 0.54 (p < 0.001), 0.45 (p < 0.001), 0.58 (p < 0.001), 0.29 (p < 0.05), and 0.72 (p < 0.001), respectively. These study models could effectively predict changes in the mean values. The benefit was driven by the effect of the intervention in ED nurses. Thus, the intervention, when applied in conjunction with routine in-service class, could exert synergistic improvements on outcomes measured in nurses.

Dilemmas and Repercussions of Workplace Violence against Emergency Nurses: A Qualitative Study.

Nurses received the highest rate of workplace violence due to their close interaction with clients and the nature of their work. There have been relatively few qualitative studies focus on nurses' perceptions of and experiences with the antecedents, dilemma and repercussions of the patient and visitor violence (PVV), leaving a considerable evidence gap. The aim of this study was to explore nurses' experience of PVV in emergency department, the impact of PVV on quality of care, and supports needed after exposure to such incidents. We conducted semi-structured interviews with a purposive and snowball sample of nurses, and analyzed the content of the interview transcripts. A total of 10 nurses were approached and agreed to participate. Those participants ranged in age from 24 to 41 years old, eight female and two male nurses, and the majority of them (80%) held a university Bachelor degree in nursing. The average time in nursing practice was 7.2 years. We conceptualized five analytical themes, which comprised: (1) multifaceted triggers and causes of PVV; (2) experiences following PVV; (3) tangled up in thoughts and struggle with the professional role; (4) self-reflexivity and adjustment; and, (5) needs of organizational efforts and support following PVV. This paper provides compelling reasons to look beyond solely evaluating the existence of workplace, and considering the perceived professional inefficacy, impacts of being threatened or assaulted in nurses. There are also urgent needs in provision of prevention and management of workplace training programs to ensure the high-quality nursing care.

Effects of Integrated Moral Reasoning Development Intervention for Management of Violence in Schizophrenia: A Randomized Controlled Trial.

Moral cognition is an important and multidimensional, but often overlooked, determinant of violence. Very few interventions have systematically examined the role of moral reasoning, anger management and problem-solving together in violence. A randomized controlled trial was conducted to comprehensively evaluate the sustained effects of an integrated Moral Reasoning Development Intervention (MRDI) in the management of repetitive violence in schizophrenia. This study placed special emphasis on essential components related to moral reasoning and violence in patients with schizophrenia. Evaluations, including measures of violence, moral reasoning, ethical valuation and judgement, decision-making, conflict management style, and personality traits, were performed at baseline, end of intervention, and 1-month follow-up after intervention. We found that MRDI was superior to treatment-as-usual, in improving moral reasoning and related variables and violence outcomes (p < 0.05). In comparison with the treatment-as-usual group (n = 22), patients in the MRDI group (n = 21) showed improved levels of moral reasoning, with decreased levels of violent behaviors. The MRDI participants also experienced significantly greater improvements or changes (p < 0.05) in their ethical valuation and judgement, decision-making style and preferences, and conflict management style. Our findings provide important implications for risk assessment and violence management and prevention.

A randomised controlled trial of the effect of music therapy and verbal relaxation on chemotherapy-induced anxiety.

AIMS: To determine the effect of music therapy and verbal relaxation on state anxiety and anxiety-induced physiological manifestations among patients with cancer before and after chemotherapy. BACKGROUND: Cancer and its treatment provoke a series of changes in the emotional sphere of the patient's anxiety. Music therapy and verbal relaxation had reported the anxiety reduction effect on patients with cancer receiving chemotherapy. Few studies have been undertaken comparing music therapy and verbal relaxation in differentiating high-normal state anxiety subsample. DESIGN: A randomised controlled trial and permuted block design were used. Outpatient chemotherapy clinic operated by a University medical centre in southern Taiwan. METHODS: Ninety-eight patients were randomised into three groups: the music therapy group received one-hour single music session; the verbal relaxation group received 30 minutes of guided relaxation; the control group received usual care. Spielberger State-Trait Anxiety Instrument, Emotional Visual Analog Scale, three biobehavioural indicators: skin temperature, heart rate and consciousness level were measured during and after chemotherapy. RESULT: Music therapy had a greater positive effect on postchemotherapy anxiety than verbal relaxation and control groups and a significantly increase in skin temperature. Patients with high state anxiety receiving music therapy had a greater drop in postchemotherapy anxiety than did the normal state anxiety subsample. CONCLUSIONS: Both music and verbal relaxation therapy are effective in reducing chemotherapy-induced anxiety. Thirty minutes of intervention initiates anxiety reduction. Patients with high state anxiety receiving chemotherapy obtain the most benefit from music or verbal relaxation. RELEVANCE TO CLINICAL PRACTICE: Prior to chemotherapy, patients with high state anxiety must be sorted from all patients as they are more responsive to interventions. Oncology nurses can offer music and verbal relaxation as adjuvant interventions to reduce chemotherapy-induced anxiety and enhance the quality of care.

Subsequent Dyslipidemia and Factors Associated with Mortality in Schizophrenia: A Population-Based Study in Taiwan.

Background: Persons with schizophrenia are at greater risk of developing subsequent medical conditions. To date, few studies have examined comprehensively the risks, mortality and survival rates in schizophrenia and subsequent dyslipidemia over different time periods. The objective of this study was to evaluate the occurrence of subsequent dyslipidemia after the diagnosis of schizophrenia, and factors associated with mortality and survival rate in patients with schizophrenia. Methods: We used a population-based cohort from Taiwan National Health Insurance Research Database, to investigate in patients whom were first diagnosed with schizophrenia during the period from 1997 through 2009, the risk of subsequent dyslipidemia during follow-up. Cumulative incidences and hazard ratios after adjusting for competing mortality risks were calculated. Results: A total of 20,964 eligible patients were included. Risks (i.e., comorbidity) and protective factors (i.e., statin use) have significant impacts on mortality. The mortality exhibits a U-shaped pattern by age. After 50, the risk of death increases with age. Risk of mortality before 50 increases with a decrease in age. Risks differed by the duration time to subsequent dyslipidemia after schizophrenia. Mean duration was 63.55 months in the survive group, and 43.19 months in the deceased group. The 5-, 10-, and 15-year survival rates for patients with schizophrenia and subsequent dyslipidemia were 97.5, 90, and 79.18%, respectively. Conclusion: Early occurrence of subsequent dyslipidemia is associated with increased overall mortality in patients with schizophrenia.

A Systematic Review of Effectiveness of Omega-3 Fatty Acid Supplementation on Symptoms, Social Functions, and Neurobiological Variables in Schizophrenia.

BACKGROUND: Disturbance of lipid, particularly omega-3 polyunsaturated fatty acid (PUFA), metabolism is associated with the etiology and symptoms of schizophrenia. Numerous clinical studies have tried to evaluate whether omega-3 PUFA supplementation can ameliorate the disorder, but the results are inconclusive. OBJECTIVES: This systematic review integrates and refines the research evidence of the effectiveness of omega-3 PUFA nutritional supplementation on schizophrenia during the different developmental phases of the disease (prodromal, first-episode, and chronic phases) and examines whether different developmental stages modulate the efficacy of omega-3 PUFA supplementation. DATA SOURCES: Scientific articles from 2000 to 2020 in PubMed/Medline, Allied Health Literature, PsychINFO, and SCOPUS following the Preferred Reporting Items for Systematic Reviews guidelines. METHODS: A systematic review was performed. We reviewed electronic databases and identified 1,266 clinical studies. Of these, 26 met the inclusion criteria. RESULTS: The effectiveness of omega-3 dietary supplementation on symptoms varies among different phases of illness. Omega-3 supplementation significantly improves positive and negative symptoms at the prodromal phase, improves mainly the negative symptoms in patients with the first-episode, and effects symptoms partly in patients with chronic schizophrenia. DISCUSSION: The effectiveness of omega-3 PUFA dietary supplementation is modulated by age, duration of untreated psychosis and illness, baseline levels of omega-3 fatty acids, and status of antioxidant capacity of patients. The important implications for psychiatric research and clinical practice developments as well as nursing care are presented and discussed.

Effects of Integrated Violence Intervention on Alexithymia, Cognitive, and Neurocognitive Features of Violence in Schizophrenia: A Randomized Controlled Trial.

Patients with schizophrenia and repetitive violence express core impairments that encompass multiple domains. To date, there have been few interventions integrating neurocognition, social cognition, alexithymia, and emotion regulation together as an approach to manage repetitive violence. The aim of this open-label randomized controlled trial was to examine more comprehensively the effectiveness of a novel Integrated Cognitive Based Violence Intervention Program on management of repetitive violence in patients with schizophrenia (vSZ). Sixty recruited patients were aged ≥20 years, diagnosed with schizophrenia for >2 years, had repetitive violent behavior within one year, and were psychiatrically hospitalized. The vSZ patients were randomly allocated to two groups and received either the intervention or treatment as usual. The intervention module, consisting of all defined 11 cognitive and social cognitive domains as well as emotion regulation, which were grouped into four modules. The intervention placed emphasis on the patients' behavioral problems or intrinsic conflicts in relation to repetitive violence. The results indicate a statistically significant trend toward reducing impulsivity, anger with resentment, physical aggression, suspicion, and hostility (p < 0.05). The intervention significantly alleviated the intensity of cognitive failure, improved the management of alexithymic features and attribution styles and errors, and fostered adequate decision-making styles and emotion regulation capacity (p < 0.05). The intervention, when applied in conjunction with psychiatric standard care, could exert synergistic effects on alexithymia and cognitive, clinical, and neurocognitive features of repetitive violence in schizophrenia. This intervention provided patients a more active role to manage their violent behavior with the involvement of alexithymia.

Use of Charlson Comorbidity Index and Nomogram to Predict Mortality in Elderly Patients with Late-Life Schizophrenia.

Objectives: Comorbid illness burden signifies a poor prognosis in schizophrenia. The aims of this study were to estimate the severity of comorbidities in elderly patients with schizophrenia, determine risk factors associated with mortality, and establish a reliable nomogram for predicting 1-, 3- and 5-year mortality and survival. Methods: This population-based study rigorously selected schizophrenia patients (≥65 years) having their first admission due to schizophrenia during the study period (2000-2013). Comorbidity was scored using the updated Charlson Comorbidity Index (CCI). Results: This study comprised 3827 subjects. The mean stay of first admission due to schizophrenia was 26 days. Mean numbers of schizophrenia and non-schizophrenia-related hospitalization (not including the first admission) were 1.80 and 3.58, respectively. Mean ages at death were 73.50, 82.14 and 89.32 years old, and the mean times from first admission to death were 4.24, 3.33, and 1.87 years in three different age groups, respectively. Nearly 30% were diagnosed with ≥3 comorbidities. The most frequent comorbidities were dementia, chronic pulmonary disease and diabetes. The estimated 1-, 3- and 5-year survival rates were 90%, 70%, and 64%, respectively. Schizophrenia patients with comorbid diseases are at increased risk of hospitalization and mortality (p < 0.05). Conclusion: The nomogram, composed of age, sex, the severity of comorbidity burden, and working type could be applied to predict mortality risk in the extremely fragile patients.
