Summary: Previous research has found a significant association between sustaining a concussion and suicidality in adolescents. However, this study found that after controlling for other relevant variables, there was no significant association between concussion and suicidality, except for a significant relationship between concussion and suicide attempts in boys.

Summary: This study investigates the association between concussions and suicidality (suicide ideation, planning, and attempts), suicide capability (physical fighting and weapon carrying), and hopelessness among adolescents. The results suggest that concussions are associated with an increased risk of suicide attempts, suicide capability, and hopelessness among male adolescents and suicide capability and hopelessness among female adolescents.

Summary: This study examined the association between sports- or physical activity-related concussions and suicidality, finding that risk factors such as persistent feelings of sadness or hopelessness, low academic grades, and substance use increase the odds of suicidality, while protective factors such as physical activity and sports team participation decrease the odds. The study used data from a nationally representative survey of US high school students and found that the association between concussions and suicidality was significant even after adjusting for demographic characteristics, with no moderation by other factors.

Summary: Research has shown a relationship between early life stress and depression, with epigenetic mechanisms playing a key role. These mechanisms involve DNA methylation, histone actions, and RNA regulation, and are of significant importance in understanding the genetic influence on psychopathology.

Summary: The link between suicidality and social disconnection is explored using a positive and negative valence systems framework in a clinical sample. The study finds that individuals with suicidality have lower levels of positive affect and less desire for future social interaction compared to those without suicidality.

Summary: As a leading cause of death worldwide, suicide has been extensively researched to better understand the factors that contribute to suicide risk or resilience. Some studies have examined the association between electroencephalography (EEG) asymmetry, which refers to differences in brain activity between the left and right hemispheres, and suicidality. This comprehensive review and meta-analysis found that EEG asymmetry was not consistently related to suicide based on the reviewed literature. While this review does not rule out all brain-based factors, the findings suggest that EEG asymmetry may not be a biomarker for suicidality.

Summary: This study aims to understand the pathway of suicide bereavement on suicide ideation by analyzing the mediating effect of complicated grief. The results show that suicide bereavement has a significant effect on suicide ideation, and complicated grief plays a mediating role in this relationship.

Summary: The study found that there was no significant association between weight and suicidal ideation, planning, or attempts among adolescents in the UAE. However, being female, older, and having lower socioeconomic status were significantly associated with increased suicidal behaviors. Increased parental involvement was associated with decreased suicidality.

Summary: A previous study found an association between concussion and suicidality in high school students in the US, but this relationship became weaker when controlling for other life stressors. This study focused on predictors of self-harm among youth who experienced a concussion in the past year, and found that certain modifiable stress factors like bullying and substance use were associated with higher risk of suicidal ideation.

Summary: The study found that individuals linked to celebrity suicide, especially young people, females, the unemployed, and those without mental illness or precipitating life events, were more likely to die by suicide. These individuals were also more likely to choose hanging as the method of suicide and leave a suicide note. English newspapers were more likely to report events linked to celebrity suicide.

Summary: The study explores the relationship between spontaneous mimicry, emotional contagion, and contagious yawning, suggesting that the latter is not strongly linked to emotional sharing but rather influenced by biased attentional processes and yawning detection. Further research is needed to understand the factors driving variability in contagious yawning beyond emotional contagion.

Summary: Open framework materials like zeolites and metalorganic frameworks have attracted significant interest due to their unique structures and appealing functionalities. In this research, new inorganic framework materials were discovered, with scaffold based on octahedral transition metal building blocks instead of tetrahedral ones. These materials exhibit distinctive structural features and interesting properties.

Summary: In recent deep clustering studies, discriminative models have shown competitive performance and are found to be equivalent to K-means under certain conditions. A new soft and regularized deep K-means algorithm is proposed, connecting state-of-the-art discriminative models directly to K-means and achieving competitive performance on image clustering benchmarks.

Summary: This narrative review suggests that blunted neurobehavioral responses to external threats may link chronic, severe, and/or multitrauma PTSD with suicide attempts. While existing evidence generally supports this proposal, more research is needed to confirm this association.

Summary: This study reports on the theoretical derivation of macroscopic thermal properties of an electrically insulating rod connected to two reservoirs. The theory predicts the temperature gradient and energy transport by linking motion amplitude cross-correlations between nearby mechanical modes. The theory relates the macroscopic clamping region where mixing occurs to the microscopic phonon mean-free-path.
