Objective:To explore the risk factors of suicidal ideation in bereavement callers of Beijing psy-chological support hotline.Methods:Bereavement callers from 2022-2023 hotline callers who were assessed for grief reactions were included in this study.Callers were assessed for current suicidal ideation by asking them if they had suicidal ideation within two weeks.The general demographic data of bereavement callers were collected,and the distress,hope and suicide risk factors of bereavement callers were assessed by hotline interview.The depression de-gree of bereavement callers was assessed by diagnostic screening scale for depression.Logistic regression analysis was used to explore the risk factors of suicidal ideation.Results:Seventy-seven point two percent(1 028/1 332)of callers reported suicidal ideation.Those who were over 25 years old(OR=0.50),with 10-16 years of education(OR=0.59),with over 16 years of education(OR=0.28),and had a high sense of hope(OR=0.41)were less likely to have suicidal ideation.Those with previous suicide history(OR=2.70),high levels of distress(OR=1.72),and high levels of depression(OR=2.86)were more likely to have suicidal ideation.Conclusion:A history of previous suicide,high levels of distress,and high levels of depression among bereavement callers were risk fac-tors for suicidal ideation.

Objective To explore the research hotspots and trends in the field of cognitive dysfunction after aneurysmal subarachnoid hemorrhage (aSAH) based on bibliometric analysis. Methods Tools such as VoSviewer, CiteSpace, and the R language Bibliometrix package were utilized to conduct a bibliometric analysis of literature related to cognitive dysfunction after aSAH retrieved from the Web of Science Core Collection (WoSCC) database, spanning from January 1, 1991, to December 31, 2023. Results A total of 262 articles involving 44 countries, 443 institutions, and 1, 328 authors were screened based on the search strategy. The United States was the country with the highest number of articles (72) and the most international collaboration. The University of Toronto was the most productive institution (18 articles). Neurosurgery and World Neurosurgery were the journals with the highest number of publications in this field, each contributing 15 articles. The articles published in Stroke were the highest in total citation frequency, with 1, 222 citations. MACDONALD R L was the most prolific author in this field (17 articles), while WONG G K C had the highest co-citation frequency (179 times). Currently, the research hotspots in cognitive dysfunction after aSAH focused on early brain injury (EBI), delayed cerebral ischemia (DCI), and cerebral vasospasm (CV). The mechanism of DCI's impact on cognitive dysfunction after aSAH represented one of the research trends in this field. Conclusion The current research hotspots in the field of cognitive dysfunction after aSAH concentrate on pathophysiological processes such as EBI, CV, and DCI. The exploration of mechanisms underlying pathophysiological changes after aSAH remains a focal point for future research in this area.

Objective To explore the risk factors for suicidal ideation among the relatives and friends of suicide victims through psychological support hotline.Methods Calls from the relatives and friends of suicide victims to the Beijing psychological support hotline between 2009 and 2023 were included.Their current suicidal ideation was assessed by asking whether they had suicidal thoughts in the past two weeks.Demographic information of the callers was collected and the severity of their depression was assessed using the depression diagnostic screening scale.Interviews were conducted to evaluate distress,sense of hope,history of suicide attempts,and suicide risk factors.Logistic regression analysis was used to explore the risk factors for suicidal ideation among callers.Results A total of 360 cases were included in this study.There were 50.3%(181 cases)of the callers reporting suicidal ideation within 2 weeks before the call.Years of education(OR=0.86,95%CI:0.79-0.94)and high levels of hope(OR=0.19,95%CI:0.11-0.32)were protective factors against suicidal ideation in callers.History of suicide attempts(OR=2.01,95%CI:1.20-3.36),high levels of distress(OR=3.28,95%CI:1.92-5.61),and high levels of depression(OR=1.73,95%CI:1.05-2.84)were independent risk factors for suicidal ideation in callers.Conclusions History of suicide attempts,high levels of distress and high levels of depression among the relatives and friends of suicide victims calling the psychological support hotline are risk factors for their own suicidal ideation.
