Often, legal claims of medical negligence and §1983 based on deliberate indifference by the correctional officials follow. Unique stable and dynamic factors and circumstances and their interaction explain most suicides. A systematic suicide screening using a well-designed suicide screening questionnaire that captures known risk factors will identify most inmates at risk if adequately used. Identification and subsequent mental health assessment set the stage for preventive intervention, monitoring, and treatment of the inmates. A multidimensional suicide prevention program saves not only lives but also the best defense against a liability lawsuit.展开更多

Methods A detailed psychological autopsy survey instrument was independently administered to 895 suicide victims in family members and close associates from 23 geographically representative locations from around the country. Results Pesticide ingestion accounted for 58% （519） of all suicides and 61% （3181519） of deaths were due to unsuccessful medical resuscitation. A substantial proportion （37%） of suicide victims did not have a mental illness. Among the 563 victims with mental illness, only 13% （76/563） received psychiatric treatment. Compared to other demographic groups, young rural females who died from suicide had the highest rate of pesticide ingestion （79%）, the lowest prevalence of mental illness （39%）, and the highest acute stress from precipitating life events just prior to the suicide. Contusion Many suicides in China are impulsive acts of deliberate self-harm following acute interpersonal crises. Prevention of suicides in China must focus on improving awareness of psychological problems, improving mental health services, providing alternative social support networks for managing acute interpersonal conflicts, limiting access to pesticides, and improving the resuscitation skills of primary care providers.展开更多

The objective of this study is to identify the relationship between the rate of suicide in contemporary society and how it can be affected by the way of suicide reporting at the same time. Qualitative method is used to analysis the data capturing from observation, interviews and textual analysis. Special attention has been paid to the news reporting in the suicide in Sri Lankan newspapers. Sinhala medium newspapers： Lankadeepa, Diwaina, Lakbima, Silumina, Dinamina, Rivira, were used as the major sample of this study. Time period is located from January 2000 to January 2010. In conclusion, Suicide has been reporting in Sri Lanka as a heroic and sensational action for the target of maximum selling and the financial benefit of media institutions. Use of Language in suicide reporting and the placement of the story in the newspaper have been two major factors that cause to glamorize the incident. Suicide reporting is highly sensational and rhetorically made by the ownership of the media and non-ethical consideration of the journalism in Sri Lanka. Victims and vulnerable are encouraged to get in to suicide and they are generally encouraged to their action for faith. Suicide should be reported in the newspaper as a problem of mental health and attention should be drawn to well inform the public on the issue. Human incidents should not be reported in media for cheap commercial purposes that indirectly chance to gain much financial profit through the highest selling and expansion. This study suggest to take necessary action to immediately make a frame of ethics of media reporting that avoids such unethical reporting in the practice of suicide reporting in Sri Lanka.展开更多

Suicidal ideation affects and disrupts the functionality of a human being regardless of age, gender, ethnicity, or even religion. This article aims to discuss suicide in general and from an Islamic perspective in specific, as research has shown that an Islamically oriented approach and intervention works better with the Muslim population in general. The paper also aims to have a broader view of how Islam categorized suicide classically and its modern implications, which also lets us explore the similarities, and differences between the Islamic perspective and different religions about suicide and related mental health concerns. A collection of both classic and modern sources was used to extract information and provide a scope of definitions to clarify suicide and religiosity concerning the teachings and opinion of Islam about the meaning of life, afterlife, and soul. It was found that the Muslim population showed a lower rate of suicide in comparison to individuals from other religions, and religious individuals showed faster recovery from suicidal ideation. Yet, Muslims are not immune to mental health conditions that would result in suicide. Therefore, further studies and research need to be conducted to understand the huge stigma around Muslim about mental health and suicide in the Muslim communities, to compare the effectiveness among the religious and the non-religious Muslims, and lastly to fill the gap as to why the Muslim population tends to be hesitant in seeking help regarding their psychological problems.展开更多

METHODS: Colorectal carcinoma cell line SW480 was transfected with adenovirus expression vector containing cytosine deaminase (CD) and thymidine kinase (TK) fusion gene. The expression of CD-TK fusion gene was detected by reverse transcriptase-polymerase chain reaction. The toxic effect of ganciclovir (GCV) and 5-fluorocytosine (5-FC) on infected cells was determined by MTT assay. The radiosensitization of double suicide gene was evaluated by clonogenic assay. RESULTS: After prodrugs were used, the survival rate of colorectal carcinoma cells was markedly decreased. When GCV and 5-FC were used in combination, the cytotoxicity and bystander effect were markedly superior to a single prodrug (X2 = 30.371, P<0.01). Both GCV and 5-FC could sensitize colorectal carcinoma cells to the toxic effect of radiation, and greater radiosensitization was achieved when both prodrug were used in combination. CONCLUSION: CD-TK double suicide gene can kill and radiosensitize colorectal carcinoma cells.展开更多

Methods During the period of 2000 to 2006, 6440 cases of poisoning suicide were reported to the telephone consultation service system of The National Center for Poisoning Control （Chinese Center for Disease Control and Prevention）. Among these records, 4728 cases had completed data for this analysis in terms of age, sex, trend of time and location, and type of poisons. Results There were 60.6% female cases with the age from 10 to 90 years old. The age of cases from 20 to 39 years accounted for 54.5% of all age groups. Both the numbers and percentage in record related to poisoning consultation of oral poisoning suicide showed an increasing tendency during the 7 years. In particular, there was a drastic increase from 2004 to 2006. In addition, the high frequency of cases occurred from May to October. Hebei, Shandong, Henan, and Anhui Provinces had the highest number of cases. Pesticide poisonings were the most common method in these cases of consultation for suicide and suicide attempts. Conclusion This study describes epidemiological characteristics in the oral poisoning suicide cases and provides scientific basis for suicide prevention interventions.展开更多
文摘BACKGROUND Appropriate care for individuals who attempt suicide and are admitted to the emergency department(ED)can prevent future suicidal behavior.It is vital to understand their sociodemographic characteristics and the effects of targeted psychological care.AIM To analyze sociodemographic characteristics of suicide attempters treated in the ED and evaluate the efficacy of psychological care.METHODS Data from 239 suicide attempters treated in the ED of the Central Hospital of Enshi Tujia and Miao Autonomous Prefecture(Hubei Province,China)between January 2021 and February 2025 were divided into 2:Control(n=108)and psychological care(n=131).The demographic characteristics and effects of the psychological care were analyzed.RESULTS The mean(±SD)age of the 239 patients[114 male(47.7%),125 female(52.3%)]was 26.25±9.3 years,of whom 122(45.2%)were single,117(48.9%)were married,and 106(44.4%)had secondary education.Thirty-eight(15.9%)patients had suicidal intent,with a mean of 1.26±0.59 suicide attempts each.Twenty-two(9.21%)patients had a family history of suicide,while 8(3.34%)had a family history of suicide attempt(s).Before intervention,mean Suicidal Intent Scale scores in the psychological nursing and control groups were 21.57±5.28 and 19.86±5.92,respectively(P>0.05).After 1 month of nursing intervention,the respective scores were 10.09±1.11 and 16.48±0.87(P<0.001);and the re-suicide rates were 11.45%(15/131)and 24.07%(26/108)(P<0.001).CONCLUSION Psychological care significantly reduces suicide risk;EDs should provide comprehensive mental health care.
文摘Recently,inflammatory cytokine profiles have been linked to suicide risk in adolescents with non-suicidal self-injury,highlighting a promising biological dimension of suicide risk assessment.Clinical translation of the cytokine profiles into practice will require frontline engagement of the workforce.Mental health nurses are frequently the most accessible professionals in schools,communities,and low-resource settings and are prime candidates to bridge this gap.By integrating psychosocial evaluation with emerging biomarker data,they can deliver systematic risk assessment,continuous monitoring,and timely intervention.This role would not replace psychiatric expertise;it would extend the reach of psychiatric services,embedding suicide prevention across the continuum of care.For health systems,nurse-led integration may enhance capacity,equity,and resilience in responding to adolescent suicide risk.This editorial demonstrates that empowering nurses to operationalize biomarker-informed strategies is needed for advancing effective and sustainable suicide prevention in this vulnerable population.

文摘BACKGROUND Suicide constitutes the second leading cause of death among adolescents globally and represents a critical public health concern.The neural mechanisms underlying suicidal behavior in adolescents with major depressive disorder(MDD)remain poorly understood.Aberrant resting-state functional connectivity(rsFC)in the amygdala,a key region implicated in emotional regulation and threat detection,is strongly implicated in depression and suicidal behavior.AIM To investigate rsFC alterations between amygdala subregions and whole-brain networks in adolescent patients with depression and suicide attempts.METHODS Resting-state functional magnetic resonance imaging data were acquired from 32 adolescents with MDD and suicide attempts(sMDD)group,33 adolescents with MDD but without suicide attempts(nsMDD)group,and 34 demographically matched healthy control(HC)group,with the lateral and medial amygdala(MeA)defined as regions of interest.The rsFC patterns of amygdala subregions were compared across the three groups,and associations between aberrant rsFC values and clinical symptom severity scores were examined.RESULTS Compared with the nsMDD group,the sMDD group exhibited reduced rsFC between the right lateral amygdala(LA)and the right inferior occipital gyrus as well as the left middle occipital gyrus.Compared with the HC group,the abnormal brain regions of rsFC in the sMDD group and nsMDD group involve the parahippocampal gyrus(PHG)and fusiform gyrus.In the sMDD group,right MeA and right temporal pole:Superior temporal gyrus rsFC value negatively correlated with the Rosenberg Self-Esteem Scale scores(r=-0.409,P=0.025),while left LA and right PHG rsFC value positively correlated with the Adolescent Self-Rating Life Events Checklist interpersonal relationship scores(r=0.372,P=0.043).CONCLUSION Aberrant rsFC changes between amygdala subregions and these brain regions provide novel insights into the underlying neural mechanisms of suicide attempts in adolescents with MDD.

文摘BACKGROUND Sensitivity to stress is essential in the onset,clinical symptoms,course,and prognosis of major depressive disorder(MDD).Meanwhile,it was unclear how variously classified but connected stress-sensitivity variables affect MDD.We hypothesize that high-level trait-and state-related stress-sensitivity factors may have different cumulative effects on the clinical symptoms and follow-up outcomes of MDD.AIM To investigate how stress-sensitivity factors added up and affected MDD clinical symptoms and follow-up results.METHODS In this prospective study,281 MDD patients were enrolled from a tertiary care setting.High-level stress-sensitivity factors were classified as trait anxiety,state anxiety,perceived stress,and neuroticism,with a total score in the top quartile of the research cohort.The cumulative effects of stress-sensitivity factors on cognitive dysfunction,disability and functional impairment,suicide risk,and depressive and anxiety symptoms were examined using an analysis of variance with linear trend analysis.Correlations were investigated further using multiple regression analysis.RESULTS Regarding high-level stress-sensitivity factors,53.40%of patients had at least one at baseline,and 29.61%had two or more.Four high-level stress-sensitivity components had significant cumulative impacts on MDD symptoms at baseline(all P<0.001).Perceived stress predicted the greatest effect sizes of state-related factors on depressive symptoms(partialη^(2)=0.153;standardizedβ=0.195;P<0.05).The follow-up outcomes were significantly impacted only by the high-level trait-related components,mainly when it came to depressive symptoms and suicide risk,which were predicted by trait anxiety and neuroticism,respectively(partialη^(2)=0.204 and 0.156;standardizedβ=0.247 and 0.392;P<0.05).CONCLUSION To enhance outcomes of MDD and lower the suicide risk,screening for stress-sensitivity factors and considering multifaceted measures,mainly focusing on trait-related ones,should be addressed clinically.

文摘Background Globally,suicide is the third leading cause of death among girls aged 15-19 years.However,there is a growing concern that suicide research has paid lttle attention to pregnant adolescent girls,particularly in lowincome and middle-income countries,including Ghana,where nearly one in seven adolescents experiences(unwanted)pregnancy.Aims To assess the prevalence and correlates of suicidal ideation and suicide attempt and the self-reported reasons for attempted suicide among pregnant adolescent girls in Ghana.Methods We collected cross-sectional data(between August 2022 and December 2023)using structured anonymous questionnaires from a sample of 449 pregnant adolescent girls(aged 14-19 years)drawn from the three geographical zones of Ghana.We applied bivariable and multivariable analysis techniques to the data.Results Overall,28.51%(95%confidence interval(Cl)24.37%to 32.93%)reported suicidal ideation,and 18.04%(95%Cl 14.59%to 21.91%)reported suicide attempt during the current pregnancy.Participants who reported attempted suicide endorsed more interpersonal reasons(eg,to communicate distress,to seek help or to influence others)than intrapersonal reasons for their attempted suicide.In the final adjusted logistic regression models,food insecurity(adjusted odds ratio(aOR)=2.69;95%Cl 1.34 to 5.41;p=0.005)was uniquely associated with increased odds of suicidal ideation.Adverse childhood experiences(a0R=3.04;95%CI 1.33 to 6.97;p=0.008),history of attempted suicide before current pregnancy(a0R=3.47;95%CI 1.27 to 9.47;p=0.015)and depression(measured by the 5-item World Health Organization Well-Being Index;aOR=0.31;95%CI 0.12 to 0.77;p=0.012)were uniquely associated with increased odds of suicide attempt.Five variables were commonly associated with increased odds of both suicidal ideation and suicide attempt:conflict with parents,alcohol use,pregnancy-related anxiety,history of attempted suicide and intimate partner violence.While being in junior high school was uniquely associated with reduced odds of suicidal ideation,intimate partner's acceptance of paternity was commonly associated with reduced odds of both suicidal ideation and suicide attempt.Conclusions Although the prevalence estimates of suicidal ideation and suicide attempt in this study are comparable with known rates among non-pregnant adolescent girls in Ghana,additional research is needed to nuance our understanding of the correlates identified in this study.The evidence aiso highlights a need for both routine antepartum primary care mental health screening for suicidality and related risks and targeted prevention and intervention programmes.

文摘Suicide is defined as the act of a person attempting to take their own life by causing death.Suicide is a complex phenomenon that is influenced by a multitude of factors,including psychosocial,cultural,and religious aspects,as well as genetic,biochemical,and environmental factors.From a biochemical perspective,it is crucial to consider the communication between the endocrine,immune,and nervous systems when studying the etiology of suicide.Several pathologies involve the bidirectional communication between the peripheral activity and the central nervous system by the action of molecules such as cytokines,hormones,and neurotransmitters.These humoral signals,when present in optimal quantities,are responsible for maintaining physiological homeostasis,including mood states.Stress elevates the cortisol and proinflammatory cytokines levels and alter neurotransmitters balance,thereby increasing the risk of developing a psychiatric disorder and subsequently the risk of suicidal behavior.This review provides an integrative perspective about the neurochemical,immunological,and endocrinological disturbances associated with suicidal behavior,with a particular focus on those alterations that may serve as potential risk markers and/or indicators of the state preceding such a tragic act.

文摘BACKGROUND Depression,non-suicidal self-injury(NSSI),and suicide attempts(SA)often co-occur during adolescence and are associated with long-term adverse health outcomes.Unfortunately,neural mechanisms underlying self-injury and SA are poorly understood in depressed adolescents but likely relate to the structural abnormalities in brain regions.AIM To investigate structural network communication within large-scale brain networks in adolescents with depression.METHODS We constructed five distinct network communication models to evaluate structural network efficiency at the whole-brain level in adolescents with depression.Diffusion magnetic resonance imaging data were acquired from 32 healthy controls and 85 depressed adolescents,including 17 depressed adolescents without SA or NSSI(major depressive disorder group),27 depressed adolescents with NSSI but no SA(NSSI group),and 41 depressed adolescents with SA and NSSI(NSSI+SA group).RESULTS Significant differences in structural network communication were observed across the four groups,involving spatially widespread brain regions,particularly encompassing cortico-cortical connections(e.g.,dorsal posterior cingulate gyrus and the right ventral posterior cingulate gyrus;connections based on precentral gyrus)and cortico-subcortical circuits(e.g.,the nucleus accumbens-frontal circuit).In addition,we examined whether compromised communication efficiency was linked to clinical symptoms in the depressed adolescents.We observed significant correlations between network communication efficiencies and clinical scale scores derived from depressed adolescents with NSSI and SA.CONCLUSION This study provides evidence of structural network communication differences in depressed adolescents with NSSI and SA,highlighting impaired neuroanatomical communication efficiency as a potential contributor to their symptoms.These findings offer new insights into the pathophysiological mechanisms underlying the comorbidity of NSSI and SA in adolescent depression.

文摘BACKGROUND Non-suicidal self-injury(NSSI)in adolescents is a strong predictor of suicide and a significant mental health problem worldwide.Previous studies have identified various risk factors for NSSI.However,studies have not explored the association between inflammatory factors and NSSI in adolescents.AIM To investigate inflammatory marker changes post-antidepressant treatment and their association with suicide risk in NSSI adolescents.METHODS The study enrolled 68 adolescents with NSSI behaviors.The participants were divided into high and low suicide risk groups(n=38 and n=30,respectively)based on their scores on the Suicide Risk Factors Assessment Scale.Symptom severity was assessed at baseline and after six weeks of treatment.Blood samples were obtained to monitor for inflammatory factors.RESULTS The high suicide risk group exhibited higher levels of interferon(IFN)-αand interleukin(IL)-10 than the low suicide risk group.Scores on the Hamilton Anxiety Rating Scale,Hamilton Depression Rating Scale,and Insomnia Severity Index decreased significantly post-treatment.Tumor necrosis factor-α,IL-10,IL-6,IL-1,and IL-12 levels decreased,whereas IFN-γ,IL-4,and IFN-αlevels increased.IL-10 levels were correlated with the severity of suicide risk factors.CONCLUSION Adolescents with NSSI exhibit distinct inflammatory markers based on suicide risk,which change following treatment.Moreover,IL-10 levels are associated with suicide risk.These biomarkers may help assess suicide risk in clinical settings.
文摘Suicide is a major and urgent issue in the field of mental health,and the United Nations has set“reducing global suicide mortality by one third by 2030”as one of its sustainable development goals.Suicide literacy refers to an individual’s ability to recognize,manage,and prevent suicide-related problems.This article offers a comprehensive review of the concepts,assessment tools,factors,and interventions of suicide literacy,with the goal of helping individuals to better understand suicidal behaviors and providing a scientific basis for developing effective suicide prevention strategies and measures to advance the progress of suicide prevention.
文摘BACKGROUND Work-family conflicts and daytime sleepiness are related to the risk of suicide.At present,no study has investigated the relationship between nurses’work-family behavioral role conflict and suicide risk.Moreover,it has not been confirmed whether,considering the effect of daytime sleepiness on suicide risk,daytime sleepiness mediates the effect of work-family behavioral role conflict and suicide risk.AIM To explore the pathway relationships among nurses'work-family behavioral role conflict,daytime sleepiness,and suicide risk.METHODS Convenience and purposive sampling methods were used to select 750 nurses from six provinces,including Jiangxi,Sichuan,and Shanxi.The work-family behavioral role conflict scale,the Chinese adult daytime sleepiness scale,and the suicide behavior questionnaire were used for the survey.The data were statistically analyzed via SPSS 25.0 software,Pearson correlation analysis was used to explore the correlations between the variables,the PROCESS 4.0 program was used for the mediation effect analysis,and the mediation effect model was tested via the bootstrap method.RESULTS Nurses'work-family behavioral role conflict and daytime sleepiness were positively correlated with suicide risk(r=734,0.717).Work-family behavioral role conflict positively predicted suicide risk(β=0.118),and daytime sleepiness positively predicted suicide risk(β=0.152).Daytime sleepiness partially mediated the role of nurses'work-family behavioral role conflict and suicide risk,with a mediation effect value of 0.046 and a mediation effect accounting for 38.98%.CONCLUSION The results of the Pearson correlation analysis and mediation effect analysis revealed that nurses'work-family behavioral role conflict has a direct effect on suicide risk and indirectly affects suicide risk through daytime drowsiness symptoms.
文摘BACKGROUND Depression is a common mental disorder among adolescents,characterized by a high rate of suicide and self-harm,which not only is devastating to families but also has a negative impact on society.Psychological factors such as impulsive personality,perceived chronic social adversity(PCSA),and sense of security are closely associated with suicide risk in adolescents with depression.Few studies have been conducted on the relationship between these factors.AIM To explore the impact of impulsive personality on suicide risk in adolescents with depression and the chain mediating effect between PCSA and sense of security.METHODS This study is a retrospective study.A total of 200 adolescents with depression who visited the Guangxi Zhuang Autonomous Region Maternal and Child Health Hospital from January 2021 to December 2023 comprised the study cohort.The PCSA scale,Security Questionnaire,Barratt Impulsiveness Scale,and Beck Scale for Suicide Ideation were used to evaluate depression.RESULTS Suicide risk was positively correlated with impulsive personality and PCSA(P<0.05),whereas sense of security was negatively correlated with suicide risk,impulsive personality,and PCSA(P<0.05).The total indirect effect of PCSA and sense of security on impulsive personality and suicide risk was 35.43%,with the mediating effect of PCSA and sense of security contributing 16.53%and 15.75%,respectively.PCSA and sense of security exhibited a chain mediating effect between impulsive personality and suicide risk,accounting for 3.15%.CONCLUSION The suicide risk of adolescents with depression is significantly associated with impulsive personality,PCSA,and sense of security.Impulsive personality affects the suicide risk of adolescents with depression both directly and indirectly,with the latter occurring via PCSA and sense of security.
文摘Mood disorders are often an indication or a sign of depression,and individuals suffering from mood swings may face higher probability and increased suicidal tendencies.Depression-also called“clinical depression”or a“depressive disorder”-is a mood disorder that adversely impacts how an individual feels,thinks,and handles daily activities,such as sleeping,eating,or working.To be diagnosed with depression,symptoms must be present most of the time,nearly every day for at least minimum of 2 to 3 weeks.Feeling sad or having low emotional energy may be common among people.For most,however,these feelings are transitory and can be managed by changing daily life routines.But for some,prolonged mood disorders can lead to depression and foster suicidal tendencies.Suicide is a major public health concern.Over 47,000 people died by suicide in the United States in 2017.It is the 10th leading cause of death overall according to NIMH(National Institute of Mental Health).Suicide is complicated and tragic,but it is often preventable.Identifying the warning signs for suicide and how to get help can be a major mitigating factor.In this short communication,we are reviewing the promise and limitations of AI(artificial intelligence)with its integrated tools such as ML(machine learning)and DL(deep learning)for mood analysis as a means for detecting early signs of depression and increased suicidal tendencies for possible suicide risk management.
文摘Inmates in jails and prisons are a high-risk group for suicide. Often, legal claims of medical negligence and §1983 based on deliberate indifference by the correctional officials follow. Unique stable and dynamic factors and circumstances and their interaction explain most suicides. A systematic suicide screening using a well-designed suicide screening questionnaire that captures known risk factors will identify most inmates at risk if adequately used. Identification and subsequent mental health assessment set the stage for preventive intervention, monitoring, and treatment of the inmates. A multidimensional suicide prevention program saves not only lives but also the best defense against a liability lawsuit.

文摘Objective To compare the characteristics of suicides in the four main demographic groups： urban males, urban females, rural males and rural females in order to help clarify the demographic pattern of suicides in China. Methods A detailed psychological autopsy survey instrument was independently administered to 895 suicide victims in family members and close associates from 23 geographically representative locations from around the country. Results Pesticide ingestion accounted for 58% （519） of all suicides and 61% （3181519） of deaths were due to unsuccessful medical resuscitation. A substantial proportion （37%） of suicide victims did not have a mental illness. Among the 563 victims with mental illness, only 13% （76/563） received psychiatric treatment. Compared to other demographic groups, young rural females who died from suicide had the highest rate of pesticide ingestion （79%）, the lowest prevalence of mental illness （39%）, and the highest acute stress from precipitating life events just prior to the suicide. Contusion Many suicides in China are impulsive acts of deliberate self-harm following acute interpersonal crises. Prevention of suicides in China must focus on improving awareness of psychological problems, improving mental health services, providing alternative social support networks for managing acute interpersonal conflicts, limiting access to pesticides, and improving the resuscitation skills of primary care providers.

文摘BACKGROUND Previous studies found several factors associated with suicide in schizophrenic patients,such as age,sex,education level,history of suicide attempts,psychotic symptoms,social factors,and substance abuse.However,there might be some additional factors that were not considered in previous studies but may be correlated with a greater likelihood of suicide attempts,such as medication and treatment.AIM To investigate the prevalence of suicide attempts and identify the risk of suicidality in hospitalized schizophrenia patients.METHODS This is a cross-sectional study of schizophrenic patients admitted to a psychiatric hospital who were 18 years of age or more.The outcomes and possible suicide risk factors in these patients were collated.The current suicide risk was evaluated using the mini-international neuropsychiatric interview module for suicidality and categorized as none(0 points),mild(1-8 points),moderate(9-16 points),or severe(17 or more points).This study used ordinal logistic regression to assess the association of potential risk factors with the current suicide risk in schizophrenic patients.RESULTS Of 228 hospitalized schizophrenia patients,214(93.9%)were included in this study.The majority(79.0%)of patients were males.Females appeared to have a slightly higher suicidality risk than males,with borderline significance.With regard to the current suicide risk assessed with the mini-international neuropsychiatric interview,172(80.4%)schizophrenic patients scored zero,20(9.4%)had a mild risk,8(3.7%)had a moderate risk,and 14(6.5%)had a severe risk.The total prevalence of current suicide risk in these schizophrenic patients was 19.6%.Based on multivariable ordinal logistic regression analysis with backward elimination,it was found that younger age,a current major depressive episode,receiving fluoxetine or lithium carbonate in the previous month,or a relatively higher Charlson comorbidity index score were all significantly and independently associated with a higher level of suicide risk.CONCLUSION The prevalence rate of suicide attempts in schizophrenia is high.Considering risk factors in routine clinical assessments,environmental manipulations and adequate treatment might prevent or decrease suicide in these patients.
文摘Suicide has been largely investigated by many researchers in a variety of perspectives. The objective of this study is to identify the relationship between the rate of suicide in contemporary society and how it can be affected by the way of suicide reporting at the same time. Qualitative method is used to analysis the data capturing from observation, interviews and textual analysis. Special attention has been paid to the news reporting in the suicide in Sri Lankan newspapers. Sinhala medium newspapers： Lankadeepa, Diwaina, Lakbima, Silumina, Dinamina, Rivira, were used as the major sample of this study. Time period is located from January 2000 to January 2010. In conclusion, Suicide has been reporting in Sri Lanka as a heroic and sensational action for the target of maximum selling and the financial benefit of media institutions. Use of Language in suicide reporting and the placement of the story in the newspaper have been two major factors that cause to glamorize the incident. Suicide reporting is highly sensational and rhetorically made by the ownership of the media and non-ethical consideration of the journalism in Sri Lanka. Victims and vulnerable are encouraged to get in to suicide and they are generally encouraged to their action for faith. Suicide should be reported in the newspaper as a problem of mental health and attention should be drawn to well inform the public on the issue. Human incidents should not be reported in media for cheap commercial purposes that indirectly chance to gain much financial profit through the highest selling and expansion. This study suggest to take necessary action to immediately make a frame of ethics of media reporting that avoids such unethical reporting in the practice of suicide reporting in Sri Lanka.
文摘Suicide is one of the most common yet serious concerns, and a worldwide subject that individuals have debated from the past to the present. Suicidal ideation affects and disrupts the functionality of a human being regardless of age, gender, ethnicity, or even religion. This article aims to discuss suicide in general and from an Islamic perspective in specific, as research has shown that an Islamically oriented approach and intervention works better with the Muslim population in general. The paper also aims to have a broader view of how Islam categorized suicide classically and its modern implications, which also lets us explore the similarities, and differences between the Islamic perspective and different religions about suicide and related mental health concerns. A collection of both classic and modern sources was used to extract information and provide a scope of definitions to clarify suicide and religiosity concerning the teachings and opinion of Islam about the meaning of life, afterlife, and soul. It was found that the Muslim population showed a lower rate of suicide in comparison to individuals from other religions, and religious individuals showed faster recovery from suicidal ideation. Yet, Muslims are not immune to mental health conditions that would result in suicide. Therefore, further studies and research need to be conducted to understand the huge stigma around Muslim about mental health and suicide in the Muslim communities, to compare the effectiveness among the religious and the non-religious Muslims, and lastly to fill the gap as to why the Muslim population tends to be hesitant in seeking help regarding their psychological problems.
文摘AIM: To investigate the killing effect and radiosensitization of double suicide gene mediated by adenovirus on colorectal carcinoma cells. METHODS: Colorectal carcinoma cell line SW480 was transfected with adenovirus expression vector containing cytosine deaminase (CD) and thymidine kinase (TK) fusion gene. The expression of CD-TK fusion gene was detected by reverse transcriptase-polymerase chain reaction. The toxic effect of ganciclovir (GCV) and 5-fluorocytosine (5-FC) on infected cells was determined by MTT assay. The radiosensitization of double suicide gene was evaluated by clonogenic assay. RESULTS: After prodrugs were used, the survival rate of colorectal carcinoma cells was markedly decreased. When GCV and 5-FC were used in combination, the cytotoxicity and bystander effect were markedly superior to a single prodrug (X2 = 30.371, P<0.01). Both GCV and 5-FC could sensitize colorectal carcinoma cells to the toxic effect of radiation, and greater radiosensitization was achieved when both prodrug were used in combination. CONCLUSION: CD-TK double suicide gene can kill and radiosensitize colorectal carcinoma cells.
文摘Objective This study analyzed patterns of suicide and suicide attempts by poisoning as reported through a national poison control system for the purpose of improving intervention and prevention. Methods During the period of 2000 to 2006, 6440 cases of poisoning suicide were reported to the telephone consultation service system of The National Center for Poisoning Control （Chinese Center for Disease Control and Prevention）. Among these records, 4728 cases had completed data for this analysis in terms of age, sex, trend of time and location, and type of poisons. Results There were 60.6% female cases with the age from 10 to 90 years old. The age of cases from 20 to 39 years accounted for 54.5% of all age groups. Both the numbers and percentage in record related to poisoning consultation of oral poisoning suicide showed an increasing tendency during the 7 years. In particular, there was a drastic increase from 2004 to 2006. In addition, the high frequency of cases occurred from May to October. Hebei, Shandong, Henan, and Anhui Provinces had the highest number of cases. Pesticide poisonings were the most common method in these cases of consultation for suicide and suicide attempts. Conclusion This study describes epidemiological characteristics in the oral poisoning suicide cases and provides scientific basis for suicide prevention interventions.
