Suicide risk in juvenile open angle glaucoma patients

AIM:To investigate the association between juvenile open angle glaucoma(JOAG)and mental health among Koreans.METHODS:This study used nationally representative data from the 8th Korea National Health and Nutrition Examination Survey(KNHANES)2021.Glaucoma diagnosis followed the International Society of Geographical and Epidemiological Ophthalmology criteria based on glaucomatous structural defects,visual field defects,corrected vision,and intraocular pressure.As outcomes,suicidal behaviors,psychiatric counseling,and depression were evaluated through mental health questionnaires.Odds ratios(ORs)with 95%confidence intervals(CIs)were estimated using logistic regression models,adjusting for covariates.RESULTS:Among 7090 participants,3446 met the inclusion criteria for analysis,and 88(2.6%)were diagnosed with open angle glaucoma(OAG).After adjusting for age,sex,and best-corrected visual acuity(VA),participants with OAG were revealed to have significantly higher odds of suicidal behaviors(i.e.,ideation,planning,or attempts)compared with those without OAG(OR:2.70;95%CI:1.12-6.54;P=0.028).This association remained significant after further adjustments for socioeconomic status,lifestyle factors,and presence of chronic conditions(P=0.031 and 0.035,respectively).However,there was no significant difference for the other two outcomes,psychiatric counseling and depression.An age-stratified analysis revealed a stronger association between OAG and suicidal behaviors in younger JOAG participants(<40y)than in older OAG participants(≥40y;OR:3.80 vs 2.22;95%CI:0.79-18.22 vs 0.56-8.80,respectively).CONCLUSION:OAG patients show a higher risk of suicidal behaviors than those without glaucoma particularly in JOAG patients.

Characteristics,causality,and suicidal behavior:a qualitative study of family members with suicide history in Wonogiri,Indonesia

Objective:This study explored the characteristics,causality,and suicidal behavior among family members with suicide history in Wonogiri,Central Java,Indonesia.Methods:Qualitative semistructured interviews were conducted with 15 family members who had made suicide attempts.The interviews directly explored the relationships among characteristics,causality,and suicidal behavior.The research data were analyzed using the Miles and Huberman approach.Results:The results indicate that there are relationships among characteristics,causality,and suicidal behaviors.The characteristics contributing to suicide attempts were male gender,age(adolescence and old age),lack of religious activities,introvert nature,low economic status,chronic diseases,unemployment,and a history of family members with suicide attempts.The causality of suicide was joblessness,economic crisis,unemployment,family conditions,personality disorder,depression,sickness,and suicide ideation.Conclusions:The findings highlight the relationships among characteristics,causality,and suicidal behaviors.Suicide occurs when individuals have some problems that they cannot solve because of the lack of family support.The causal factors were related to one another,which caused the suicidal behavior.One of the most effective suicide prevention strategies is educating the community on how to identify suicidal signs and increase social supports.

On the role of impulsivity and decision-making in suicidal behavior

Suicide risk constitutes a complex set of interacting demographic, clinical, psychobiological and environmental variables. Impulsivity is a long-known risk factor for suicide attempts. However, research based on clearer conceptual refinement in this area is imperative. One emerging field of study is that of decision-making. Impulsivity involves a failure of higher-order control, including decision-making. Using standardized operational definitions that take into consideration relevant aspects of impulsivity, including state- and trait-components and a deeper understanding of the process of decision-making in the suicidal mind, we may come a step closer to understanding suicidality and winning the fight in this scourge of human suffering.

BDNF methylation and mRNA expression in brain and blood of completed suicides in Slovenia

BACKGROUND Suicide is a major public health problem.Worldwide,around 800000 people die by suicide every year.Suicide is a multifactorial disorder,with numerous environmental and genetic risk factors involved.Among the candidate genes,changes in the BDNF locus at the gene,epigenetic,mRNA,and protein expression levels have been implicated in psychiatric disorders,including suicidal behavior and completed suicides.AIM To investigate changes in BDNF methylation and expression of four alternative BDNF transcripts for association with completed suicide.METHODS This case-control study included 42 unrelated male Caucasian subjects,where 20 were control subjects who died following acute cardiac arrest,and 22 were suicide victims who died by hanging.DNA and RNA were extracted from brain tissue(Brodmann area 9 and hippocampus)and from blood.DNA methylation and mRNA expression levels were determined by targeted bisulfite next-generation sequencing and reverse-transcription quantitative PCR.Statistical analysis was done by use of two-tailed Student’s t tests for two independent samples,and the Benjamini-Hochberg procedure was implemented for correction for multiple comparisons.RESULTS In DNA from brain tissue,there were no significant differences in BDNF methylation between the study groups.However,data showed significantly reduced DNA methylation of the BDNF region upstream of exon I in blood samples of suicide victims compared to the controls(5.67±0.57 vs 6.83±0.64,P_(corr)=0.01).In Brodmann area 9 of the brain of the suicide victims but not in their hippocampus,there was higher expression of BDNF transcript I-IX(NM_170731.4)compared to the controls(0.077±0.024 vs 0.05±0.013,P=0.042).In blood,expression analysis for the BDNF transcripts was not feasible due to extensive RNA degradation.CONCLUSION Despite the limitations of the study,the obtained data further support a role for BDNF in suicidality.However,it should be noted that suicidal behavior is a multifactorial disorder with numerous environmental and genetic risk factors involved.

Associations among depression, suicidal behavior, and quality of life in patients with human immunodeficiency virus

AIM: To investigate the potential associations among major depression, quality of life, and suicidal behavior in human immunodeficiency virus(HIV) patients. METHODS: A detailed MEDLINE search was carried out to identify all articles and book chapters in English published from January 1995 to January 2015. RESULTS: Based on the main findings, the prevalence of major depressive disorder(MDD) ranged from 14.0% to 27.2%. Furthermore, the prevalence of suicidal ideation varied from 13.6% to 31.0% whereas, attempted suicides were reported to range from 3.9% to 32.7%. Interestingly, various associated risk factors for both depression and suicide were identified in HIV patients. Finally, consistent associations were reported among MDD, suicidal ideation, and poor quality of life in individuals living with HIV. CONCLUSION: Although additional studies are needed to elucidate this complex association, our results suggest the importance of early detection of both MDD and suicidality in patients living with HIV.

Suicidal behavior-advances in clinical and neurobiological research and improvement of prevention strategies

Suicide is the 14^(th)leading cause of death worldwide.It is responsible for 1%-5%of all mortality.This article highlights the latest developments in universal,selective,and indicated prevention strategies.Concerning universal suicide prevention,current research has shown that strategies such as restricting access to lethal means(e.g.,control of analgesics and hot-spots for suicide by jumping)and school-based awareness programs are most efficacious.Regarding selective prevention,substantial progress can be expected in psychological screening methods for suicidal behavior.The measurement of implicit cognition proved to be more valid in predicting future suicide attempts than classic clinical assessment.Latest developments are smartphone-based interventions and realtime monitoring of suicidal behavior.Great effort has been made to establish valid neurobiological screening methods(e.g.,genetic and epigenetic risk factors for suicide,hypothalamic-pituitary-adrenal axis)without yielding a major breakthrough.Potentially,multiple biomarkers rather than a single one are necessary to identify individuals at risk.With regard to indicated prevention in form of psychopharmacological treatment,recent pharmacoepidemiological studies and meta-analyses have supported a protective role of antidepressants,lithium,and clozapine.However,the data concerning a specific anti-suicidal effect of these drugs are currently not consistent.Promising results exist for ketamine in reducing suicidal ideation,independently of its antidepressant effect.Concerning psychotherapy,recent findings suggest that psychotherapeutic interventions specifically designed to prevent suicide re-attempts are most efficacious.Specifically,cognitive behavioral therapy and psychodynamic therapy approaches proved to decrease the number of suicide re-attempts significantly.

Psychiatric hospitalization during the two SARS-CoV-2 pandemic waves:New warnings for acute psychotic episodes and suicidal behaviors

BACKGROUND The subsequent waves of the severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)pandemic have represented a dramatic health emergency characterized by significant consequences on mental health.Diachronic variations in the incidence rates of acute relapse of psychiatric disorders may represent significant"sentinel events"for assessing the mental health response to an unprecedented stressful event.AIM To investigate the variation in psychiatric hospitalization rates and differences in sociodemographic and clinical-psychopathological peculiarities at Bologna"Maggiore"General Hospital Psychiatric Ward(GHPW)between the first two waves SARS-CoV-2 pandemic and the same periods of the previous 3 years.The secondary purpose of the study was to suggest a diachronic response pathway to stress by reporting additional literature data on coping strategies.METHODS This observational and retrospective study collected information on admission to the GHPW at the"Maggiore"Hospital in Bologna in the index periods defined as follows:the first period between February 24,2020 and April 30,2020(first epidemic wave)and the second period between October 8,2020,and January 7,2021(second pandemic wave).Absolute numbers and proportion of admitted patients,their sociodemographic and clinical-psychopathological characteristics were compared with the same parameters recorded in the two same periods of the previous 3 years.No strict inclusion or exclusion criteria were provided in the data collection to collect information on all patients requiring acute psychiatric hospitalization.RESULTS During the first wave,there was a significant reduction in hospitalization rates,although there was a simultaneous increase in compulsory hospitalizations and the acute relapse of schizophrenia spectrum and other psychotic disorders.During the second wave,hospitalization rates reached those recorded during the same period of the previous 3 years,mainly due to the rise of bipolar and related disorders,depressive disorders,anxiety disorders,trauma-and stressor-related disorders and suicidal behaviors.CONCLUSION The coping strategies adopted during the first wave of the SARS-CoV-2 pandemic protected the vulnerable population from the general risk of clinical-psychopathological acute relapse,even if they increased the susceptibility to run into schizophrenia spectrum and other psychotic disorder relapses.In the medium-long term(as in the second pandemic wave),the same strategies do not play protective roles against the stress associated with the pandemic and social restriction measures.Indeed,during the second wave of the SARS-CoV-2 pandemic,an increase in total hospitalization rate,suicidal behaviors and the incidence rate of bipolar and related disorders,depressive disorders,anxiety disorders,trauma-and stressorrelated disorders was observed.

Effect of dialectical behavior therapy on the serum neurotransmitters and cytokines in depression patients with suicidal tendency

Objective: To explore the effect of dialectical behavior therapy on the serum neurotransmitters and cytokines in depression patients with suicidal tendency. Methods: A total of 98 depression patients with suicidal tendency who were treated in the hospital between August 2014 and August 2017 were collected and divided into the control group (n=49) and the research group (n=49) by random number table. Control group received routine drug therapy, and study group received dialectical behavior therapy combined with drug therapy. The differences in serum levels of monoamine neurotransmitters, nerve function indexes and acute phase proteins were compared between the two groups of patients. Results: After treatment, serum NE, 5-HT and DA levels of research group were higher than those of control group;serum MBP and NSE levels of research group were lower than those of control group while BDNF level was higher than that of control group;serum Tf level of research group was higher than that of control group while Hp level was lower than that of control group. Conclusion: Dialectical behavior therapy intervention can effectively optimize the nerve function and improve the overall state of depression patients with suicidal tendency.

Reviewing Self-Injuries Behavior in Macaques: The Role of Early Experience and Genetics in an Integrated Non-Human Model

Genetic differences in non-human primates and the context where they were reared are important in the determination of their behaviors. Some studies suggest that Self-Injurious Behavior results from stress or anxiety, but some macaques appear to be more vulnerable to acquiring Self-Injurious Behavior. Vulnerability and risk for socially reared macaques of developing Self-Injurious Behavior increased when they experienced early adverse events and suffered from consequent stress. Stressful events can cause alterations in the neuroendocrine and neuropeptide systems associated with the regulation of stress and anxiety. Dysregulation in these systems contributes to the occurrence of anxious episodes that lead to self-harm. This could be used by those animals to counteract the effects of anxiety, causing euphoria by releasing endogenous opioids. In developing an integrative approach of Self-Injurious Behavior, we propose the diathesis-stress model to illustrate how the environment and genetics are influenced as well, taking rhesus monkeys as an example. Rhesus macaques and humans have essentially the same gene 5-HTT as well as functional polymorphism. The allelic variation in the region promoting the serotonin transporter gene (5-HTT) was associated with significant differences in the number of depressive symptoms and contributions to social reward and punishment. Growing up without the mother and the rearing environment are important risk factors for developing abnormal behaviors. The main idea is that monkeys who carry short 5-HTT allele and are reared with their peers (without their mother) suffer from
