Summary: This review focuses on the neurobiological abnormalities, particularly genetic and epigenetic abnormalities, associated with suicidal behavior and the potential for modeling these abnormalities in animals. It aims to enhance the current understanding of suicidal behavior and potentially aid in the development of treatment opportunities and risk assessment.

Summary: There is a strong association between Toxoplasma gondii and suicidal behavior, with evidence showing a higher risk of suicide attempts in individuals with T. gondii IgG seropositivity. This infection may be linked to endophenotypes and state-dependent risk factors of suicidal behavior.

Summary: Adolescents with self-harm thoughts and behaviors need prompt access to appropriate professional care, but the study found that they often experience significant delays in seeking help, and more severe psychopathology prolongs the help-seeking duration.

Summary: False Aha! moments can be induced experimentally using the False Insight Anagram Task (FIAT), which combines semantic priming and visual similarity manipulations. In a preregistered experiment, participants were tested to see if warnings and explanations could reduce their susceptibility to false insights. Simple warnings did not decrease false insights, but participants given a detailed explanation experienced a slight reduction. These findings demonstrate the robust and persuasive nature of false insights.

Summary: This study found that feelings of entrapment and deficits in social problem-solving skills are associated with risk for suicidal behavior in individuals with depression. The association between these risk factors and suicidal behavior varies with age, with entrapment being a better discriminator in older adults. Impulsive problem-solving style is associated with past suicide attempts across the adult lifespan.

Summary: Individuals with eating disorders may have low self-esteem and be at risk for suicidal behavior. The study found that self-hate is more strongly related to suicidal behavior than dissociation in individuals with bulimia nervosa. Targeting self-hate may be important in treating and preventing suicide in eating disorders.

Summary: The study reveals that in the type-II X-ray bursts of MXB 1730-335, hard X-rays lag behind soft X-rays by 3 seconds, providing a new perspective for research. The energy spectrum of all bursts is nonthermal, indicating the possible presence of a coronal source.

Summary: The suicide mortality rate per 100 000 population (SMRP) in Japan has shown a consistent decrease until the COVID-19 pandemic outbreak. This study aimed to identify trends and factors associated with suicidal mortality and motives among students in Japan from 2007 to 2022. The findings revealed that school-related, health-related, and family-related problems were major motives for suicide among students. The impact of health-related and family-related motives varied with age, and the rates associated with interpersonal relationships increased significantly during the pandemic.

Summary: Despite a significant amount of clinical research on risk factors for the process of suicide, there is still insufficient understanding of the mechanisms and pathways behind the emergence and progression of suicidal thoughts. Psychological pain, a central concept in various psychological theories, has been associated with suicidal ideation and behavior. However, many questions regarding the concept of psychological pain and its predictive role in suicidal behavior remain unanswered and require further research.

Summary: The study found that childhood trauma, affective lability, and aggressive and impulsive traits can predict changes in suicidal ideation (SI) variability. Those with high SI variability show greater increases in SI after stressful events, but SI variability did not change over the course of 2 years. This suggests that variable SI may be a trait increasing risk for impulsive suicidal behavior.

Summary: This study investigated the prevalence of suicidal behavior, suicidal ideation, and patterns among youth in the Anywaa zone of Southwest Ethiopia. The findings indicated high prevalence of suicide-related behaviors and ideations among youths in the area, with hanging and drug overdose or poisoning being the most common patterns. The study recommends collaboration between government, NGOs, and FBOs, along with healthcare providers and counselors, to create awareness and establish programs targeting the youth.

Summary: Despite the high risk of suicide, mental health research on American Indian/Alaskan Native (AIAN) emerging adults is lacking. This study aims to explore the risk and protective factors of suicidality among AIAN-identifying individuals. The results show high rates of suicidal ideation, particularly among gender minority-identifying students. Non-suicidal self-injury, self-perceived need for help, and flourishing are associated with suicidality across all gender identities. It is crucial to emphasize student awareness of mental health services and further investigate protective factors and community support for AIAN college students.

Summary: Cannabis has been recognized for thousands of years, but recent research has highlighted the crucial role of the endocannabinoid system in regulating mood, impulsivity, and decision-making, with dysfunction potentially increasing the risk of negative mood and cognitive impairments. The literature suggests that targeting the endocannabinoid system could be a viable approach for treating various neuropsychiatric disorders.

Summary: Recent studies have shown a significant association between activated immune-inflammatory and nitro-oxidative pathways and suicide attempts. Inflammation, immune activation, nitro-oxidative stress, lowered neuroprotection, and increased neurotoxicity may explain why psychiatric patients exhibit increased suicidal behaviors.
