Influence and mechanism of intolerance of uncertainty on anxiety / 四川精神卫生

The purpose of this paper is to review the research on the influence and mechanism of intolerance of uncertainty （IU） on anxiety both at home and abroad in recent years. IU refers to the individual's disgust response due to the intolerance of perceived lack of prominent， critical or sufficient information， and it has individual tendency. IU plays an important role in the occurrence and development of anxiety， but the specific process and mechanism remain unclear. This paper reviews the influence of IU on anxiety， and clarifies its mechanism of action on the generation and development of anxiety from the perspectives of cognition， emotion and behavior， so as to provide references for preventing the development of general anxiety into anxiety disorders and developing new psychological intervention and treatment strategies.

A Cross Sectional Study on Sexual Dysfunction and Quality of Life in Patients with Bipolar Affective Disorder

Introduction: Sexual dysfunction is one of the leading causes of psychological distress in bipolar affective disorder patients. The current study aims to study the relationship between sexual dysfunction and quality of life in patients with Bipolar affective disorder in remission. Materials and methods: A cross-sectional study of purposively sampled bipolar patients in remission (N=60) was conducted in an OPD setting. After reinforcing confidentiality and privacy, data was collected and analyzed. Results: 73% with BD reported impaired sexual function. About 51.7% and 48.3% of male and female participants, respectively, had at least one form of sexual dysfunction. Better sexual function was associated with a higher degree of satisfaction with sexual life and higher QoL score. Conclusion: Sexual dysfunction is associated impaired quality of life, poor functioning and poor medication adherence. Hence, it should be made a routine practice to evaluate and address the problem of sexual dysfunction in patients with Bipolar affective disorder.

A cross-sectional comparative study of functioning in patients with bipolar depression and patients with unipolar depression

Background: Bipolar affective disorder is an episodic illness in which patient suffers from unexpected change in affect like elated mood episode (mania) followed by either depressed mood with period of inter episode euthymia. The disease in comparison to unipolar depression starts in early thirties, more severe symptoms and with more detriment in functioning and wellbeing. Aim and Objectives: The present study asses the level of global functioning of bipolar depressive patients in different domains and data compared with unipolar depressive patients. Materials and Methods: This study was done at a tertiary center in India. The study included 30 patients with bipolar depression in study group and 30 patients with unipolar depression included in control group. In all the patients of both groups, relevant scales, that is, back depression inventory and global assessment of functioning (GAF) were applied. These data were statistically analyzed by SPSS software. Results: On Comparison of global assessment of functioning scores between both groups the GAF score in bipolar depressive patients (SD ± 50.03 [4.75]) had significantly lower score as compared to unipolar depressive patients (62.37 [SD ± 11.50]), also patients show significant negative correlation. (?0.559) of GAF score and total Beck Depression Inventory score in case group (bipolar depressive patients). Conclusion: These findings of greater impairment in global functioning may be interpreted by understanding that life of patients with bipolar depression also complicated by having episode or episodes of manic symptoms in addition to their depressive episodes while patients with unipolar depression are experiencing depressive episodes only.

Resonancia magnética nuclear funcional en estado de reposo en pacientes con trastorno bipolar: más allá de la eutimia / Resting-state functional nuclear magnetic resonance imaging in patients with bipolar disorder: beyond euthymia

Resumen Introducción: La resonancia magnética funcional en estado de reposo (RMf-ER) permite identificar redes de conectividad funcional completas y los posibles correlatos neuronales de trastornos psiquiátricos. Se revisa la literatura sobre RMf-ER y trastorno bipolar (TB) haciendo énfasis en los hallazgos en las fases de manía, hipomanía y depresión. Métodos: Es una revisión narrativa de la literatura en la que se buscaron artículos en PubMed y EMBASE con las palabras clave en inglés "bipolar disorder" AND "resting state", sin límite en la fecha de publicación. Resultados: Los estudios de pacientes con TB en fases de manía e hipomanía sometidos a RMf-ER muestran resultados concordantes en cuanto a la disminución de la conectividad funcional cerebral entre la amígdala y algunas regiones corticales, lo cual indica que esta conexión funcional tendría alguna implicación en la regulación normal del afecto. Los pacientes en fase depresiva muestran disminución en la conectividad funcional cerebral, pero como son varias las estructuras anatómicas implicadas y las redes neuronales reportadas en los estudios, no es posible compararlos. Conclusiones: Hay disminución en la conectividad funcional en los pacientes con TB, pero la evidencia actual no permite establecer cambios específicos en redes de conectividad funcional cerebral puntuales. Sin embargo, ya hay algunos hallazgos que muestran correlación con la clínica de los pacientes.

ABSTRACT Introduction: imaging in the resting state (R-fMRI) Functional nuclear magnetic allows the identification of complete functional connectivity networks and the possible resonance neuronal correlations of psychiatric disorders. The literature on R-fMRI and bipolar disorder (BD) will be reviewed, emphasising the findings in the phases of mania, hypomania and depression. Methods: It is a narrative review of the literature in which articles were searched in PubMed and Embase, with the key words in English "bipolar disorder" AND "resting state", without limit on the date of publication. Results: The studies of BD patients in the mania and hypomania phases who underwent R-fMRI show concordant results in terms of decreased functional cerebral connectivity between the amygdala and some cortical regions, which indicates that this functional connection would have some implication in the normal affect regulation. Patients in the depressive phase show a decrease in functional brain connectivity, but as there are seve-ral anatomical structures involved and neural networks reported in the studies, it is not possible to compare them. Conclusions: There is a decrease in functional connectivity in patients with BD, but current evidence does not allow establishing specific changes in specific functional brain connectivity networks. However, there are already some findings that show correlation with the patients' symptoms.

Sintomatología depresiva y calidad de vida en estudiantes de medicina en alta latitud sur / Depression and seasonal sensitivity among medical students residing in high southern latitudes

Background: There is no evidence for the association of depressive symptoms with the sense of well-being of undergraduate medical students residing in high southern latitudes (HSL). Aim: To assess the frequency of depressive symptoms and its relationship with seasonal sensitivity and quality of life in medical students residing in HSL. Material and Methods: The Beck anxiety and depressive symptoms inventory, the seasonal pattern assessment questionnaire and the quality-of-life questionnaire of the WHO were applied to 102 medical students residing in Magallanes, Chile. Results: Fifty-two percent of respondents reported some degree of depressive symptoms. These symptoms were significantly associated with the seasonal pattern score (r = 0.432, p < 0.01). They were also inversely associated with parameters of physical health and psychosocial health (r = −0.567, p < 0.01 and r = −0.708, p < 0.01, respectively). There was also a correlation between depressive and anxiety symptoms. Conclusions: Depressive symptoms are common in medical students residing in HSL and they are associated with seasonal sensitivity and quality of life measures.

Clinical and demographic profile of patients treated with electro convulsive therapy from a tertiary care psychiatry hospital in North India

Background: Electro-convulsive therapy (ECT) refers to the electrical stimulation of the brain to produce seizures for therapeutic purpose. This study was undertaken with the aim of exploring the clinical and demographic profile of patients treated with ECT from a tertiary care psychiatry hospital in north India.Methods: It was a retrospective descriptive study of patients who were treated with ECT after admission in the inpatient psychiatry unit of Institute of mental health and neurosciences Kashmir during a period of one year (March 2017 to February 2018).Results: A total of 70 patients received ECT during the course of one year. About 72.85% of the patients belonged to 20-39 years age group. Female patients constituted more than half of the subjects (55.71%). Review of diagnostic profile showed that majority of patients receiving ECT were suffering from Schizophrenia (35.71%), followed by bipolar affective disorder (28.57%), depressive disorder (28.57%), schizoaffective disorder (4.28%) and substance induced mood/psychotic disorders (2.85%). A significant majority of subjects (57.13%) received about 7-9 ECT sessions. No any major complications were noted during ECT treatment.Conclusions: This study suggests that ECT, use as a treatment modality is common in adults between 20 to 39 years of age and females with Schizophrenia being the most common indications.

Exploring the role of therapeutic drug monitoring and regular supervision in optimizing quality of life in patients of bipolar affective disorder receiving lithium therapy in a tertiary care teaching hospital: a prospective observational study

Background: Lithium is considered first line drug effective in treating manic and mixed episodes of bipolar affective disorders throughout the globe. But the chronic and heterogenous nature of disease, along with toxicity of lithium often make patients non-adherent to medication as well as diminished health related quality of life. Present study was done to find out the prospect of regular supervision and follow up with therapeutic drug monitoring in optimization of lithium therapy based on health-related quality of life outcomes.Methods: It was a prospective, non-randomized, observational study of a cohort of subjects who are suffering from bipolar affective disorders and on lithium therapy. Patients were regularly followed up with therapeutic drug monitoring and personalized interview with questionnaires like WHO Quality of Life Score (QOL-Bref), Montgomery-Asberg Depression Scale (MADRS) and Medication Adherence Rating Scale (MARS).Results: Results revealed there was significant improvement in health-related quality of life of patients who were monitored with therapeutic drug monitoring and prescribed lithium therapy.Conclusions: Hence to maintain patients’ quality of life improved throughout the cycle of bipolar disorder spectrum, regular follow-up visits with monitoring of serum levels of lithium is needed, so that adverse effects would be minimal and adherence to medication become optimal. These optimal dosing resulting in optimal benefit to patients can be achieved with the involvement of clinical pharmacological consultation.

Irritabilidad como síntoma transdiagnóstico / Irritability as a transdiagnostic Symptom

Resumen. La irritabilidad es un síntoma transdiagnóstico que atraviesa la barrera de las patologías internalizantes y externalizantes. Se define como un umbral bajo para experimentar la ira en respuesta a la frustración y es uno de los síntomas más comunes en niños y adolescentes. Las conductas relacionadas con la ira apropiadas para el desarrollo tienden a reflejar frustración en contextos esperados, mientras que la irritabilidad crónica es inapropiada para la situación. La presentación de la irritabilidad, crónica o episódica, es crucial para comprender su significado psicopatológico, en particular porque las estructuras de la irritabilidad episódica y crónica son separables y permanecen estables a lo largo del tiempo. Existen varios estudios acerca de la irritabilidad en patologías como trastorno afectivo bipolar y trastorno de desregulación disruptiva del estado del ánimo, en ambos casos es importante plantearse como punto de partida la identificación de la episodicidad. La irritabilidad también se encuentra presente en el trastorno de personalidad límite observándose dentro de una inestabilidad afectiva debida a una reactividad notable del estado de ánimo. Estas emociones tienen un correlato anatómico relacionado con deficiencias de los circuitos frontolímbicos. Para el manejo de la irritabilidad en las distintas patologías, la evidencia del tratamiento incluye terapia cognitivo conductual, intervención de los padres, mindfulness, pero existe una necesidad apremiante de investigación sobre el tratamiento farmacológico complementario.

Irritability is a transdiagnostic symptom that crosses the barrier between internalizing and externalizing pathologies. It is defined as a low threshold to experience anger in response to frustration and it is one of the most common symptoms in children and adolescents. Behaviors related to appropriate developmental anger tend to reflect frustration in expected contexts, while chronic irritability is inappropriate to the situation. The presentation of irritability, chronic or episodic, is crucial to understanding its psychopathological meaning, particularly because the structures of episodic and chronic irritability are separable and remain stable over time. There are several studies about irritability in pathologies such as bipolar affective disorder and disruptive mood dysregulation disorder, in both cases it is important to consider the identification of episodicity as a starting point. Irritability is also present in borderline personality disorder, where it is expressed as an affective instability due to a remarkable reactivity of the state of mind. These emotions have been anatomically related to deficiencies of the frontolimbic circuits. For the management of irritability in different patholo-gies, the evidence includes cognitive behavioral therapy, parental intervention, mindfulness, but there still is a pressing need for research on complementary pharmacological treatment.

Increased levels of plasma IL-1b and BDNF can predict resistant depression patients

SUMMARY BACKGROUND: There is no strong evidence on the link between inflammatory profile and pattern of drug treatment response in depressive patients that could result in Coronary Artery Disease occurrence. OBJECTIVE: This study aimed to compare the subclinical atherosclerosis markers, inflammatory profile, and BDNF production in Resistant Depression (RD) or Bipolar Affective Disorder (BAD) patients under conventional treatment. METHODS: The population evaluated was comprised of 34 RD, 43 BAD, and 41 controls. Subclinical atherosclerosis markers were evaluated using ultrasonography, tomography, and exercise stress test. Plasma concentrations of TNFα, IL-1β, IL-6, and BDNF were measured using Luminex100™. The usCRP concentration was measured using turbidimetric immunoassay. IL1B, IL6, and TNFA expression were determined using TaqMan®. For the statistical analysis, the significance level was established at p<0.05. RESULTS: Concerning subclinical atherosclerosis markers, only O2 consumption was reduced in the BAD group (p = 0.001). Although no differences were found in gene expression, BDNF and IL-1β plasma concentration was increased in the RD group (p = 0.002 and p = 0.005, respectively) even with an antidepressant treatment, which suggests that these drugs have no effect in IL-1β secretion and that the inflammasome may play a role in therapy response. CONCLUSION: Taken together, both BDNF and IL-1β plasma concentrations could be used to the early identification of RD patients.

RESUMO FUNDAMENTAÇÃO: Não há fortes evidências sobre a associação entre o perfil inflamatório e o padrão de resposta ao tratamento medicamentoso em pacientes depressivos que podem resultar em ocorrência de doença coronariana. OBJETIVO: O objetivo deste estudo foi comparar os marcadores de aterosclerose subclínica, o perfil inflamatório e a produção de BDNF em pacientes com Depressão Resistente (DR) ou Transtorno Afetivo Bipolar (BAD) sob tratamento convencional. MÉTODOS: A população avaliada incluiu 34 RD, 43 BAD e 41 controles. Os marcadores de aterosclerose subclínica foram avaliados por ultrassonografia, tomografia e teste de esforço. As concentrações plasmáticas de TNFα, IL-1β, IL-6 e BDNF foram medidas utilizando Luminex100TM. A concentração de usCRP foi medida por imunoensaio turbidimétrico. A expressão de IL1B, IL6 e TNFA foi determinada usando TaqMan®. Para as análises estatísticas, foi estabelecido o nível de significância de p < 0,05. RESULTADOS: Quanto aos marcadores de aterosclerose subclínica, apenas o consumo de O2 foi reduzido no grupo BAD (p = 0,001). Embora não tenham sido encontradas diferenças na expressão gênica, a concentração plasmática de BDNF e IL-1β foi aumentada no grupo RD (p = 0,002 e p = 0,005, respectivamente) mesmo sob tratamento antidepressivo, o que sugere que esses medicamentos não têm efeito na secreção de IL-1β e que o inflamassomo pode desempenhar um papel na resposta terapêutica. CONCLUSÃO: Juntas, as concentrações BDNF e IL-1β poderiam ser usadas para a identificação precoce de pacientes com DR.

Avaliação da eficácia da psicoeducação domiciliar individual em relação à psicoeducação em grupo para pacientes com transtorno afetivo bipolar / Evaluation of effectiveness of individual psychoeducation household compared to the psychoeducation group therapy for patients with bipolar affective disorder

Introdução: Vários ensaios clínicos têm demonstrado a alta eficácia de programas para a prevenção de recaídas com base na psicoeducação, estando esta intervenção psicossocial entre as mais amplamente estudadas. Trata-se de uma intervenção bastante útil para o sistema de saúde público brasileiro, considerando sua curta duração, baixo custo e fácil execução por profissionais de saúde. Evidências indicam o formato de grupo com boa aplicabilidade, porém há uma carência de estudos que comprovem a eficácia da psicoeducação em visitas domiciliares. Objetivo: Avaliar a eficácia da Psicoeducação Domiciliar na recuperação sintomática, funcional e na adesão ao tratamento de indivíduos com TAB de médio e longo prazo, em comparação com a Psicoeducação Grupal. Metodologia: Estudo follow up, randomizado, controlado, com 45 pacientes portadores de TAB tipo I ou II, de acordo com os critérios do DSM-V TR; com pontuação <=17 na Escala de Depressão de Hamilton (HAM-D) e <=15 na Escala de Mania de Young (YOUNG). A distribuição dos sujeitos em três grupos foi feita por meio de randomização estratificada. O grupo de Intervenção Domiciliar (ID), composto por 15 pacientes, recebeu, além do tratamento farmacológico, visitas domiciliares com intervenção psicoeducacional. O grupo de Intervenção em Grupo (IG), composto por 15 pacientes, recebeu, além do tratamento farmacológico, abordagem psicoeducacional em formato de grupo realizada no serviço de saúde mental. O Grupo Controle (GC), composto por 15 pacientes, recebeu apenas o tratamento farmacológico padrão, sem intervenção psicoeducacional. Os instrumentos de avaliação utilizados foram a escala de HAM-D para sintomas de depressão, e YOUNG para sintomas de mania. A escala para avaliar a recuperação funcional foi a WHOQOL-brief. Para avaliação de níveis de estresse percebido, foi utilizada a Escala de Estresse Percebido (EEP). Além disso, utilizou-se, para avaliar a adesão medicamentosa, a Escala de Medida de Adesão ao Tratamento (MAT) e avaliação dos níveis plasmáticos de medicamentos. Resultados: Ao final do estudo, o grupo de intervenção domiciliar apresentou melhores taxas de adesão medicamentosa, quando comparado aos outros grupos do estudo (p=0,02). O efeito da psicoeducação, na ID e na IG, com relação à diminuição das taxas de recaídas, foi altamente notável no seguimento de 12 meses quando comparados ao GC (p=0,03 e p=0,02 respectivamente). ID e IG apresentaram elevação dos escores de qualidade de vida com significância estatística, enquanto o GC apresentou queda significativa dos escores do início do estudo e após 12 meses de seguimento. Conclusão: A Psicoeducação Domiciliar apresentou-se mais eficaz na adesão medicamentosa que a Psicoeducação Grupal e o tratamento usual. Ainda, o presente estudo evidenciou que a Psicoeducação em seu formato domiciliar individual e em seu formato de grupo, realizado no serviço de saúde mental, apresenta eficácia na prevenção de recaídas e recorrências, na melhora da qualidade de vida e na melhora da adesão medicamentosa em pacientes com TAB, em comparação com o Grupo Controle

Introduction: Several clinical trials have demonstrated the high effectiveness of psychoeducation-based programs designed to prevent relapse, this being the psychosocial intervention more widely studied. This is a very useful intervention for the Brazilian public health system, considering its short duration, low cost and easy execution by health professionals. Signs indicate that the group format has good applicability, however there is a lack of studies that prove the effectiveness of psychoeducation in home visits. Aim: To evaluate the effectiveness of Domiciliary Psychoeducation in symptomatic, functional recovery, and adherence to the treatment of individuals with Bipolar Affective Disorder in medium and long term, compared to psychoeducation group therapy performed in the mental health service. Methodology: This is a randomized, controlled, follow up study, with 45 patients with bipolar I or II, according to the DSM-V TR; with score <=17 on the Hamilton Depression Scale (HAMD) and <=15 on the Young Mania Scale (YOUNG). The distribution of patients in three groups was made by using of stratified randomization. The Domiciliary Intervention group (DI), consisting of 15 patients who received in addition to pharmacological treatment, home visits with psychoeducational intervention. The Intervention Group (IG), composed of 15 patients who received in addition to the pharmacological treatment, a psychoeducational approach in a group format, performed in mental health service. The Control Group (CG), composed of 15 patients who received only standard pharmacological treatment, without psychoeducational intervention. The assessment instruments used were the HAM-D scale for depression symptoms, and the YOUNG scale for mania symptoms. The WHOQOL-Brief scale was used to assess functional recovery. Perceived Stress Scale (PSS) was used to measure perceived stress levels. To evaluate drug adherence, the Treatment Adherence Instrument (MAT) was used as measure the evaluation of plasma levels of medications. Results: At the end of the study, the DI had better rates of drug adherence when compared to the other study groups (p = 0.02). The effect of psychoeducation on DI and IG in relation to decreased relapse rates was highly evident at 12 months follow up, when compared to CG (p = 0.03 and p = 0.02, respectively). The DI and IG presented an increase in quality of life scores with statistical significance, while the CG showed an expressive decrease in the scores at the beginning of the study and after 12 months of follow-up. Conclusion: The Domiciliary Psychoeducation was more effective in drug adherence than group psychoeducation and treatment as usual. Furthermore, the present study showed that Psychoeducation in its individual domiciliary format and in its group format, carried out in mental health service, presents effectiveness in prevention of relapses and recurrences, as well as in the improvement of quality of life and in the improvement of medication adherence in patients with bipolar affective disorder, when compared to the Control Group

Depressão e transtorno afetivo bipolar ­ existe associação com a periodontite? / Depression and bipolar affective disorder ­ is there an association with periodontitis? - literature review

Estudos epidemiológicos sugerem que a depressão pode alterar a instalação e a progressão da doença periodontal. O processo inflamatório, induzido pela depressão e o biofilme dentário, podem atuar sinergicamente estimulando uma intensa resposta do sistema imunológico, influenciando a progressão das doenças periodontais. O objetivo do presente trabalho é revisar a literatura em relação aos principais trabalhos que investigaram a possível correlação entre a depressão e a doença periodontal. Concluiu-se que a maioria dos estudos publicados até o momento sugerem que a depressão pode alterar significativamente a resposta do hospedeiro, tanto no nível comportamental quanto imunológico. Em relação ao transtorno afetivo bipolar e a periodontite, a maioria dos estudos publicados, até o momento, não apresentam estratégias metodológicas que avaliem corretamente a possível associação entre a doença periodontal e o transtorno bipolar especificamente. São necessários maiores estudos com metodologias que envolvam as características epidemiológicas, microbiológicas e imunológicas dessa possível associação, propiciando um melhor entendimento da doença.

Epidemiological studies suggest that depression can after the onset and progression of periodontal disease. The inflammatory process induced depression and biofilm can synergistically stimulate an intense immune response influencing the progression of periodontal diseases. The aim of this paper is to review the literature on the main studies that investigated the possible correlation between depression and periodontal disease. It was concluded that most studies published suggests that depression can significantly alter the host response at both the behavioral and immune aspects. In relation to bipolar affective disorder and periodontitis, most of the studies published do not present methodological strategies that correctly evaluate the possible association between periodontal disease and bipolar disorder specifically. More studies are needed with methodologies that involve the epidemiological, microbiological and immunological characteristics of this possible association, providing a better understanding of for a possible association.

Association of G-Protein β3 Subunit C825T Polymorphism with Seasonal Variations in Mood and Behavior

OBJECTIVE: Seasonal affective disorder and seasonal changes in mood and behavior are associated with several genes that regulate circadian rhythms. In this study, we investigated the relationship between the C825T polymorphism of the G-protein β3 subunit and seasonal variations in mood and behavior in a young healthy Korean population. METHODS: A total of 507 young Korean participants were recruited through a newspaper advertisement, and their seasonality was evaluated by the Korean version of the Seasonal Pattern Assessment Questionnaire to assess the global seasonality score (GSS). We analyzed the CC, CT, and TT genotypes and their association with the GSS score and subscales. RESULTS: T allele carriers of the GNB3 C825T polymorphism were more likely to score higher on body weight and GSS. In the female group, the T allele carriers obtained significantly high total GSS and its subscale scores for mood, body weight, energy level, and appetite; however, differences in genotypes and allele carriers were also observed in the male participants. CONCLUSION: These results suggested that GNB3 C825T polymorphism plays a role in seasonal variations in mood, body weight, energy level, and appetite in a Korean population, particularly in females.

The research advance on the α4β2 acetylcholine receptor and depression / 药学学报

Depression is currently the most popular disease in the world with a high suicide rate. Selective 5-HT reuptake inhibitors have been used as first-line drugs in clinics, but the therapeutic effect is greatly limited. The pathogenesis of depression is complicated, meanwhile the cholinergic hypothesis has received more and more attention. A large number of clinical and preclinical studies have shown that antagonists and partial agonists acting on nicotinic acetylcholine receptors have a significant effect on antidepressant therapy, which can improve the hippocampus recognizes, influence rewards and anxiety systems controlled by the ventral midbrain and ventral tegmental area, and regulate the amygdala pressure system, thereby improving mood and relieving depression. At present, the relationship between the cholinergic system and depression is still undergoing a lot of research. In this article, the relationship between α4β2 nicotinic acetylcholine receptor (nAChRs) and depression is reviewed to provide a reference for study of new anti-depression drugs.

Paraoxonase (PON1) L55M and Q192R polymorphisms in major depression and bipolar affective disorder

Abstract Background Oxidative and nitrosative stress pathways, along with immune-inflammatory response, might play an important role in the pathogenic mechanisms underlying major depression and bipolar disorder. Objective The aim of the present study is to investigate paraoxonase 1 polymorphisms and its correlations with disease parameters in patients with major depression and bipolar affective disorder. Methods PON1 L55M and Q192R single nucleotide polymorphisms were analyzed in a group consisted of 100 patients with major depression, and 100 patients with bipolar affective disorder and 96 healthy controls. Polymorphisms were analyzed by using polymerase chain reaction. Results Our findings reported no association between Q192R and L55M polymorphisms of PON1 and major depression and bipolar disorder. Additionally, there was no association between the PON1 genotypes and disease variables in both depressed and bipolar patients. Discussion Evaluating the different stages of patients with affective disorders and and investigating the connection between PON1 polymorphisms and treatment outcomes will help us to clarify the relationship between PON1 and mood disorders.

Efficacy of Sodium Valproate and Olanzapine in treating bipolar affective disorder 'mania' at a tertiary care hospital in Nepal: A comparative study

Background and Objectives: Bipolar affective disorder, mania is the mood of an abnormally elevated arousal energy level or a state of heightened overall activation with enhanced affective expression together with lability of affect. The objective of the study was to compare the efficacy of sodium valproate and olanzapine in bipolar affective disorder, mania patients at a tertiary care hospital in NepalMaterial and Methods: A randomized observational prospective open label study was conducted for one and half year at College of Medical Sciences-Teaching Hospital (CMS-TH), Bharatpur, Nepal in the Psychiatry Department. Sixty patients diagnosed with bipolar affective disorder, mania were enrolled. 30 patients received sodium valproate and 30 patients received olanzapine. Patients were monitored and evaluated on baseline (day 0), day 7 and day 30 and compared to the baseline for the severity of illness using the 11-item Young Mania Rating Scale (YMRS).Results: The mean baseline YMRS score for all cases on sodium valproate (n=30) on day 0 was 38.87 ± 3.73, while it was reduced to 13.90 ± 1.95 (p < 0.001) on day 30. Similarly, the mean baseline YMRS score for all cases on olanzapine (n=30) on day 0was 40.83 ± 6.50, while it was reduced to 14.47 ± 2.83 (p < 0.001) on day 30.The mean decrease in YMRS score by sodium valproate was 64.24% and by olanzapine was 64.56%.Conclusion: Treatment with sodium valproate and olanzapine significantly improves the mean mania ratings score and there is no statistically significant difference in efficacy of both the drugs in patients diagnosed with bipolar affective disorder, mania.

Correlations between social support and effective disorder perceived by nurses in operating rooms / 现代临床护理

Objective To investigate the status quo of social support and effective disorder nurses perceived in the operating room and analyze the correlation between them. Methods A total of 200 nurses in the operating room of four general hospitals in Guangxi Zhuang Autonomous Region were enrolled to investigate the social support and the effective disorders using the perceived social support scale (PSSS) and Toronto Alexithymia Scale (TAS). Results The total scores by PSSS and TAS were (66.08 ± 10.64) and ( 53 . 85 ± 8 . 89 ) , respectively . The scores by PSSS and its dimensions were all negatively correlated with the score by TAS ( r=-0 . 492 , P < 0 . 05 ) . Conclusions The nurse-perceived social support is generally at the medium or above level and their affective disorder at a lower level. The nursing managers should pay attention to the nurses in the operating room, taking corresponding measures to improve their affective disorder and improve the quality of nursing.
