Summary: Oxytocin plays a role in anxiety suppression, anti-stress, psychosocial behavior, and reproductive functions; responds to various stressful stimuli; maintains stability, adjusts adaptive set points, and promotes adaptive responses to stressors; involved in treating stress-related disorders.

Summary: Animals respond to stimuli from their surroundings, and owls in captivity demonstrated different temperaments and glucocorticoid metabolite levels when challenged with predators. Adjectives indicating passiveness, vulnerability, and attentiveness were correlated with shyness, and owls with higher shyness scores showed higher post-predator challenge glucocorticoid metabolite levels. However, there were no significant differences in glucocorticoid metabolite levels before and after the predator challenge. This study confirms the relationship between shy temperament and adrenal response in nocturnal raptorial birds and provides non-invasive methods to assess the welfare of captive species.

Summary: Starting from Hans Selye's stress physiology, researchers have been investigating the physiological mechanisms linking stress to health and disease. They have focused on the link between psychological stress and cardiovascular disease (CVD), the leading cause of death in the United States. Studies have shown that psychological stress is an independent risk factor for CVD, and it can lead to increased systemic inflammation, contributing to CVD development. Physical activity has been found to buffer against the harmful effects of psychological stress by strengthening stress response systems and immune system, reducing stress-induced inflammation, and attenuating mechanisms associated with CVD development. Additionally, the COVID-19 pandemic has provided a model for understanding the stress-health relationship.

Summary: This paper explores the importance of adaptive changes for survival and the critical role of energetic resource regulation. It discusses the physiological changes accompanying stress and their relationship with loss of confidence in a system's predictions, leading to depressive symptoms. By identifying the hierarchical controllers of energy resources, an etiological pathway from allostatic overload to depression is established.

Summary: The successful transfer of farmed post-smolt Atlantic salmon depends on stress responses and cognitive functions, which may be challenged by increasing oceanic temperatures. This study examined the effects of transferring fish to different temperatures on stress responses and cognitive gene expression. The results showed that lower temperatures maintained normal stress responses, while higher temperatures inhibited stress responses and cognitive functions.

Summary: This study proposes three models to explain the disparities in psychological distress and suicidality among sexual minority individuals based on recalled childhood gender nonconformity and maltreatment. The findings suggest that bisexual individuals are more likely to experience maltreatment and suicidal ideation as childhood gender nonconformity increases. Additionally, bisexual individuals report more psychological distress and a higher likelihood of lifetime suicidal ideation and attempts compared to lesbian/gay individuals as maltreatment increases. The direct effects of sexual orientation on maltreatment, distress, and suicidality are stronger than the indirect effects via maltreatment or gender nonconformity. The study highlights the importance of understanding early lived experiences of sexual minority individuals and the differences between lesbian/gay and bisexual individuals in these experiences.

Summary: Resilience is defined as maintaining or quickly recovering mental health during and after adversity. The challenge lies in operationalizing resilience and determining factors leading to good mental health outcomes in stress-exposed individuals. The proposed FRESHMO paradigm involves monitoring stress exposure and mental health problems regularly to study mental health reactivity to stress.

Summary: This study examined the role of allostatic load in drug use, finding that long-term use of cocaine or opioids may increase allostatic load. Lengthy histories of problematic non-medical substance use could accelerate the increase in allostatic load, indicating an increased risk of chronic diseases.

Summary: This paper discusses the common symptoms of depressive, anxiety, and trauma-related disorders, as well as the dilemma in classifying and choosing diagnostic therapies for these disorders. By using an iESP model, the disorders are placed on a continuum of precision-weighting dysregulation, and the relationship between anxiety and depressive stress responses is explored.

Summary: Posttraumatic stress disorder (PTSD) and chronic pain are common and co-morbid among veterans. Moral injury (MI), resulting from traumatic experiences conflicting with moral beliefs, is also associated with pain. This study examined the relationship between exposure to potentially morally injurious events (PMIEs) and different types of pain, finding that betrayal was associated with overall pain intensity, particularly in women.

Summary: This study investigated the stress response of Little Penguins to an introduced predator and conspecific in two different habitats in South Australia. The results showed that individuals from high-disturbance colonies exhibited higher vigilance and heart rate responses compared to low-disturbance colonies.

Summary: The study identified 10,769 potentially transgender veterans using a combination of GID and non-GID data elements, finding that relying solely on GID diagnosis codes is the most reliable approach for identifying transgender individuals in the VHA of the VA.

Summary: Allostasis supports the homeostatic control of biological variables in mammals, allowing them to adapt and survive in challenging environments. The brain plays a crucial role in eliciting neural and neuroendocrine responses to these challenges. Reproductive function, although essential for species survival, can be compromised in response to immediate challenges, with impacts on kisspeptin and gonadotropin-releasing hormone neuronal activity.

Summary: The study found that there was no significant change in adult erythrocyte telomere length between consecutive breeding seasons in barn swallows. Second-year individuals showed the highest increase in circulating CORT concentrations following restraint, and female stress response declined during the breeding season. Additionally, telomere shortening was associated with the stress response, suggesting that individual variation in stress response may affect telomere dynamics.
