UNASSIGNED: Warning signs serve as proximal indicators of suicide risk, making early recognition imperative for effective prevention strategies. This study aimed to explore self-identified suicide warning signs among Chinese patients with mood disorders based on safety planning framework.
UNASSIGNED: Researchers collaborated with patients to develop a safety plan and compiled warning signs based on it. Word frequency and network analysis were conducted to identify key warning signs. Directed content analysis categorized these signs into cognitive, emotional, behavioral, or physiological themes according to the suicide mode theory. Additionally, we examined potential variations in reported warning signs among participants with different demographic characteristics, including age, gender, and history of suicide attempts.
UNASSIGNED: \"Low mood\" and \"crying\" emerged as prominent warning signs, with \"social withdrawal\" closely following. Patients commonly reported emotional themes during suicidal crises, often experiencing two to three themes simultaneously, primarily focusing on emotional, behavioral, and physiological themes. Males exhibited a higher proportion of concurrently reporting three sign themes compared to females (P < 0.05), while no difference was observed in warning signs among patients with other demographic traits.
UNASSIGNED: This study offers a nuanced understanding of warning signs among mood disorder patients in China. The findings underscore the necessity for comprehensive suicide risk management strategies, emphasizing interventions targeting emotional regulation and social support. These insights provide valuable information for enhancing suicide prevention and intervention efforts.

UNASSIGNED: In the aftermath of bereavement, our research explores the subtleties of Prolonged Grief Disorder (PGD), focusing particularly on its correlation with suicidal behaviors and their variation across genders. This study seeks to elucidate the impact of gender on these behaviors among individuals suffering from PGD, thereby enhancing our understanding and facilitating the development of tailored therapeutic interventions.
UNASSIGNED: By November 24th, 2023, we had rigorously reviewed key databases such as PubMed, Web of Science, Cochrane Library, PsycINFO, and Embase. Independently, two researchers conducted detailed interviews and filled out questionnaires with participants to gather demographic information and record instances of prolonged grief disorder. The study also meticulously tracked occurrences of suicidal ideation, suicide attempts, suicide deaths, and self-injury among the participants.
UNASSIGNED: The findings indicate that 22.34% of males reported suicidal ideation (95% CI: 21.33-23.35), a figure that rises to 26.84% among females (95% CI: 25.99-27.69). Notably, 12.11% of males attempted suicide (95% CI: 11.49-12.72), marginally surpassing the 9.60% observed in females (95% CI: 9.17-10.04). More striking disparities were observed in suicide deaths, with rates for males at 3.66% (95% CI: 3.32-4.00) compared to a notably higher 7.12% for females (95% CI: 6.44-7.81). Furthermore, the incidence of self-injury was lower among males, at 2.48% (95% CI: 2.03-2.94), than in females, who reported a rate of 5.09% (95% CI: 4.69-5.49). These patterns underscore the critical need for gender-specific interventions aimed at reducing these significant disparities.
UNASSIGNED: This study distinctly underscores the profound impact of gender on the manifestation of suicidal behaviors in individuals afflicted with prolonged grief disorder. It reveals that females are more prone to suicidal ideation, self-injury, and suicide deaths, while males predominantly exhibit a higher incidence of suicide attempts and risk-taking behaviors. These unmediated trends highlight the necessity for gender-specific clinical interventions tailored to address particular behaviors and modify prevalent patterns that typically resist conventional approaches.

Suicidal thoughts and behaviors (STBs) are increasing among young people (aged 12-24 years) in China. Although Ecological Momentary Assessment (EMA) has been increasingly used to study STBs worldwide, no study has been conducted on young people with mood disorders (MD) in China. This mixed-method study aimed to evaluate the feasibility and acceptability of suicide risk monitoring in 75 young people with MD. Participants completed five to eight daily EMA surveys and wore smart bands for the EMA study. Semi-structured interviews were used to collect feedback. High adherence to EMA surveys (73.0 %) and smart bands (87.4 %) indicated feasibility. Participants reported an overall positive experience with the EMA study (helpful, friendly, and acceptable). Additionally, the reasons they were willing to comply with the EMA study were: (1) seeing the possibility of returning to \"normal,\" and (2) experiencing the process of returning. However, a small proportion of participants had negative experiences (e.g., annoyance and missing prompts). The results of this mixed-methods study provide preliminary support for the feasibility and acceptability of using EMA (combined smartphones and wearable sensor devices) to assess suicidality among young people with MD in the Chinese cultural and social context.

BACKGROUND: The prevalence of self-injury and suicide is higher than the general population of people living with HIV/AIDS (PLWHA). However, the results reported in existing studies are highly variable in China. The purpose of this systematic review and meta-analysis was to synthesize the currently available high-quality evidence to explore the prevalence and influence factors of self-injury and suicide among PLWHA in China.
METHODS: We retrieve literature written in Chinese and English through databases such as PubMed, Embase, Web of Science, Cochrane Library, SinoMed, CNKI, WanFang Database, and CQVIP from inception to 1 September 2022. Sata 16.0 software was used for analysis.
RESULTS: A total of 28 studies were included with a sample size of 1,433,971 and had a satisfactory quality score of ≥ 5. The prevalence among PLWHA in China were 30% for suicidal ideation (SI), 5% for suicide attempt (SA), 8% for suicide plan (SP), 7% for attempted suicide (AS), and 3‰ for completed suicide. High stigma (OR = 2.94, 95%CI: 1.90 - 4.57), depression (OR, 3.17; 95%CI, 2.20 - 4.57), anxiety (OR, 3.06; 95%CI, 2.23 - 4.20), low self-esteem (OR, 3.82, 95%CI, 2.22 - 6.57), high HIV related stress (OR, 2.53; 95%CI, 1.36 - 4.72), and unemployment (OR, 2.50; 95%CI, 1.51 - 4.15) are risk factors for SI; high social support (OR, 0.61; 95%CI, 0.44 - 0.84) and spouse infected with HIV (OR, 0.39; 95%CI, 0.21 - 0.74) are protective factors for SI; depression (OR, 1.62; 95%CI, 1.24 - 2.13), high aggression (OR, 4.66; 95%CI, 2.59 - 8.39), and more negative life events (OR, 2.51; 95%CI, 1.47 - 4.29) are risk factors for AS; high level of education (OR, 1.31; 95%CI, 1.21 - 1.43) is risk factor for CS.
CONCLUSIONS: Figures indicate that approximately one-third of PLWHA had suicidal ideation, and three out of 1,000 completed suicide in China. Positive events are protective factors for self-injury and suicide among PLWHA, while negative events are risk factors. This suggests that psychosocial support and risk assessment should be integrated into the care of PLWHA.

Suicide is a severe public health issue globally. Accurately identifying high-risk lung cancer patients for suicidal behavior and taking timely intervention measures has become a focus of current research. This study intended to construct dynamic prediction models for identifying suicide risk among lung cancer patients. Patients were sourced from the Surveillance, Epidemiology, and End Results database, while meteorological data was acquired from the Centers for Disease Control and Prevention. This cohort comprised 455, 708 eligible lung cancer patients from January 1979 to December 2011. A Cox proportional hazard regression model based on landmarking approach was employed to explore the impact of meteorological factors and clinical characteristics on suicide among lung cancer patients, and to build dynamic prediction models for the suicide risk of these patients. Additionally, subgroup analyses were conducted by age and sex. The model\'s performance was evaluated using the C-index, Brier score, area under curve (AUC) and calibration plot. During the study period, there were 666 deaths by suicide among lung cancer patients. Multivariable Cox results from the dynamic prediction model indicated that age, marital status, race, sex, primary site, stage, monthly average daily sunlight, and monthly average temperature were significant predictors of suicide. The dynamic prediction model demonstrated well consistency and discrimination capabilities. Subgroup analyses revealed that the association of monthly average daily sunlight and monthly average temperature with suicide remained significant among female and younger lung cancer patients. The dynamic prediction model can effectively incorporate covariates with time-varying to predict lung cancer patients\' suicide death. The results of this study have significant implications for assessing lung cancer individuals\' suicide risk.

BACKGROUND: Suicide has emerged as a critical public health concern during the COVID-19 pandemic. With social distancing measures in place, social media has become a significant platform for individuals expressing suicidal thoughts and behaviors. However, existing studies on suicide using social media data often overlook the diversity among users and the temporal dynamics of suicide risk.
OBJECTIVE: By examining the variations in post volume trajectories among users on the r/SuicideWatch subreddit during the COVID-19 pandemic, this study aims to investigate the heterogeneous patterns of change in suicide risk to help identify social media users at high risk of suicide. We also characterized their linguistic features before and during the pandemic.
METHODS: We collected and analyzed post data every 6 months from March 2019 to August 2022 for users on the r/SuicideWatch subreddit (N=6163). A growth-based trajectory model was then used to investigate the trajectories of post volume to identify patterns of change in suicide risk during the pandemic. Trends in linguistic features within posts were also charted and compared, and linguistic markers were identified across the trajectory groups using regression analysis.
RESULTS: We identified 2 distinct trajectories of post volume among r/SuicideWatch subreddit users. A small proportion of users (744/6163, 12.07%) was labeled as having a high risk of suicide, showing a sharp and lasting increase in post volume during the pandemic. By contrast, most users (5419/6163, 87.93%) were categorized as being at low risk of suicide, with a consistently low and mild increase in post volume during the pandemic. In terms of the frequency of most linguistic features, both groups showed increases at the initial stage of the pandemic. Subsequently, the rising trend continued in the high-risk group before declining, while the low-risk group showed an immediate decrease. One year after the pandemic outbreak, the 2 groups exhibited differences in their use of words related to the categories of personal pronouns; affective, social, cognitive, and biological processes; drives; relativity; time orientations; and personal concerns. In particular, the high-risk group was discriminant in using words related to anger (odds ratio [OR] 3.23, P<.001), sadness (OR 3.23, P<.001), health (OR 2.56, P=.005), achievement (OR 1.67, P=.049), motion (OR 4.17, P<.001), future focus (OR 2.86, P<.001), and death (OR 4.35, P<.001) during this stage.
CONCLUSIONS: Based on the 2 identified trajectories of post volume during the pandemic, this study divided users on the r/SuicideWatch subreddit into suicide high- and low-risk groups. Our findings indicated heterogeneous patterns of change in suicide risk in response to the pandemic. The high-risk group also demonstrated distinct linguistic features. We recommend conducting real-time surveillance of suicide risk using social media data during future public health crises to provide timely support to individuals at potentially high risk of suicide.

UNASSIGNED: Evidence on the association of early intervention services (EISs) with self-harm and suicide among patients with first-episode schizophrenia (FES) at older than 25 years is lacking.
UNASSIGNED: To examine changes in self-harm and suicide rates among patients with FES before and after the implementation of an EIS program.
UNASSIGNED: This population-based cohort study conducted among 37 040 patients aged 15 to 64 years with FES between January 1, 2001, and March 31, 2020, used electronic medical records from the Hong Kong Clinical Data Analysis and Reporting System. All patients were followed up from the first diagnosis of schizophrenia (the index date) until the date of their death or the end of the study period (March 31, 2021), whichever came first. Statistical analysis was performed from July to November 2023.
UNASSIGNED: The EIS extended the Early Assessment Service for Young People With Early Psychosis (EASY) program from patients aged 15 to 25 years to those aged 15 to 64 years (EASY Plus). The exposure was the implementation of the EASY Plus program in April 2011. The exposure period was defined as between April 2012 and March 2021 for the 1-year-time-lag analysis.
UNASSIGNED: The outcomes were monthly rates of self-harm and suicide among patients with FES before and after the implementation of the EASY Plus program. Interrupted time series analysis was used for the main analysis.
UNASSIGNED: This study included 37 040 patients with FES (mean [SD] age at onset, 39 [12] years; 82.6% older than 25 years; 53.0% female patients). The 1-year-time-lag analysis found an immediate decrease in self-harm rates among patients aged 26 to 44 years (rate ratio [RR], 0.77 [95% CI, 0.59-1.00]) and 45 to 64 years (RR, 0.70 [95% CI, 0.49-1.00]) and among male patients (RR, 0.71 [95% CI, 0.56-0.91]). A significant long-term decrease in self-harm rates was found for all patients with FES (patients aged 15-25 years: RR, 0.98 [95% CI, 0.97-1.00]; patients aged 26-44 years: RR, 0.98 [95% CI, 0.97-0.99]; patients aged 45-64 years: RR, 0.97 [95% CI, 0.96-0.98]). Suicide rates decreased immediately after the implementation of the EASY Plus program among patients aged 15 to 25 years (RR, 0.33 [95% CI, 0.14-0.77]) and 26 to 44 years (RR, 0.38 [95% CI, 0.20-0.73]). Compared with the counterfactual scenario, the EASY Plus program might have led to 6302 fewer self-harm episodes among patients aged 26 to 44 years.
UNASSIGNED: This cohort study of the EASY Plus program suggests that the extended EIS was associated with reduced self-harm and suicide rates among all patients with FES, including those older than 25 years. These findings emphasize the importance of developing tailored interventions for patients across all age ranges to maximize the benefits of EISs.
