Soybean oil supplement induces increased approaching behavior to humans and alters serotonin concentrations in horses.

Enhancement of human-horse interaction is crucial for safety in equine management, as poor relationships between humans and horses can lead to accidents. Serotonin is a neurotransmitter that is highly related to social affinity in animals and several studies have been documented that supplementation of tryptophan, which is a precursor of serotonin, can increase calmness of horses. This study aimed to assess the effect of tryptophan through soybean oil supplementation on serotonin concentrations and the behavior of horses.

Changes in sex differences in mental health over time: the moderating effects of educational status and loneliness.

Background: Limited evidence exists regarding how sex differences in mental health are changing over time, especially in the context of recent health and economic adversities.

Aims: To examine the temporal shifts in mental health issues among males and females, and explore the influence of education and loneliness on these trends.

Methods: Data were utilized from the 2020 to 2023 Monitor study, a repeated cross-sectional survey of adults 18 years and older in Ontario, Canada.

"Using the right tools and addressing the right issue": A qualitative exploration to support better care for intimate partner violence, brain injury, and mental health.

Background: Intimate partner violence (IPV) is a global public health crisis. Often repetitive and occurring over prolonged periods of time, IPV puts survivors at high risk of brain injury (BI). Mental health concerns are highly prevalent both among individuals who have experienced IPV and those who have experienced BI, yet the interrelatedness and complexity of these three challenges when experienced together is poorly understood.

"A whole ball of all-togetherness": The interwoven experiences of intimate partner violence, brain injury, and mental health.

Background: Intimate partner violence (IPV) is a global public health crisis, with physical violence leaving IPV survivors at high risk of brain injury (BI). Both BI and IPV have significant physical, psychological, cognitive, and social impacts, including a high risk of mental health concerns, yet there is limited exploration of IPV survivors' experiences with BI and mental health. This study aimed to explore the BI- and mental health-related needs and experiences of IPV survivors from the perspectives of survivors and service providers with the objective of developing knowledge translation materials to raise awareness and support survivors and service providers in addressing these concerns.
