Individuals respond differently to traumatic experiences including their propensity to develop post-traumatic stress disorder (PTSD). Understanding individual differences in PTSD vulnerability will allow the development of improved prevention and treatment options. Here, we characterized fear conditioning and extinction in rats selectively bred for differences in their locomotor response to a novel environment. Selectively bred high responder (bHR) and low responder (bLR) male rats are known to differ in their emotional reactivity on a range of measures of spontaneous anxiety- and depressive-like behaviors...

Neurosteroids are essential for aiding proper fetal neurodevelopment. Pregnancy compromises such as preterm birth, prenatal stress and intrauterine growth restriction are associated with an increased risk of developing behavioural and mood disorders, particularly during adolescence. These pathologies involve the premature loss or alteration of trophic steroid hormones reaching the fetus leading to impaired neurodevelopment. While the specific programming mechanisms are yet to be fully elucidated, in adult life, dysfunctions of allopregnanolone action are prevalent in individuals with depression, post-traumatic stress disorder and anxiety disorders...

Post-traumatic stress disorder (PTSD) is a serious mental illness that affects current and former military service members at a disproportionately higher rate than the civilian population. Prior studies have shown that PTSD symptoms follow multiple trajectories in civilians and military personnel. The current study examines whether the trajectories of PTSD symptoms of veterans separated from the military are similar to continuously serving military personnel. The Millennium Cohort Study is a population-based study of military service members that commenced in 2001 with follow-up assessments occurring approximately every 3 years thereafter...

Current events within the military and professional sports have resulted in an increased recognition of the long-term and debilitating consequences of traumatic brain injury. Mild traumatic brain injury accounts for the majority of head injuries, and posttraumatic headache is the most common adverse effect. It is estimated that between 30% to 90% of traumatic brain injuries result in posttraumatic headache, and for a significant number of people this headache disorder can continue for up to and over a year post injury...

BACKGROUND: The meniscus injury and post-traumatic knee osteoarthritis (PTOA) following anterior cruciate ligament (ACL) lesions often cause great burdens to patients. Ghrelin, a recently identified 28-amino-acid peptide, has been shown to inhibit inflammation and perform as a growth factor for chondrocyte. OBJECTIVE: This study was aimed at investigating ghrelin concentration in synovial fluid and its association with the degree of meniscus injury, articular degeneration, and clinical severity in patients suffering from anterior cruciate ligament (ACL) deficiency...

A naturalistic study of a brief treatment program for The impact of chronic trauma can be longstanding, affecting survivor affect regulation, consciousness, interpersonal functioning, perceptions of self and others, self-regulation, and somatic experience. There is a growing consensus that multi-modal and staged approaches to treatment are necessary to promote healing. However, empirical investigations of such treatments are still needed. The current study used a naturalistic design to examine the impact of a brief, yet intensive, outpatient program on complex PTSD symptoms and attachment classification among women with histories of chronic trauma...

To identify factors fostering Post-traumatic growth (PTG) is very important in order to promote PTG itself through specific psychological interventions. To this end, we investigated PTG and its relationship with clinical and psychological variables in a sample of 108 females breast cancer survivors. Results showed that women with higher depressive symptoms presented lower levels of PTG than women without. Moreover, women who had undergone combined treatment presented higher levels of PTG than women who had not...

This study aimed to investigate the role of ongoing relationships with the deceased in facilitating post-traumatic growth among suicide-loss survivors. Sample comprised 58 suicide-loss survivors, 48 sudden-death, and 53 natural-death bereaved individuals, who completed questionnaires assessing the two-track model of bereavement, grief, and growth-related characteristics. Suicide-loss survivors reported lower levels of positive relationships with the deceased than did the other groups. Interaction was found between relational-active grieving and type of death in predicting post-traumatic growth...

Damage to cutaneous nerves inhibits wound healing in patients. Results from animals on the nerve contributions to healing are various and sometimes contradictory. Here, we aim to clearly define the collective role of central, caudal, and rostral nerves in ear wound healing of mice, rats, and rabbits. These wounds heal with minimal contraction like wounds in humans. We resected central, caudal, and rostral nerves at the base of ear pinnae by microsurgery and created excisional full-thickness skin wounds in the pinnae neurologically downstream from the resections...

BACKGROUND: Epilepsy is a common and debilitating consequence of traumatic brain injury (TBI). Seizures contribute to progressive neurodegeneration and poor functional and psychosocial outcomes for TBI survivors, and epilepsy after TBI is often resistant to existing anti-epileptic drugs. The development of post-traumatic epilepsy (PTE) occurs in a complex neurobiological environment characterized by ongoing TBI-induced secondary injury processes. Neuroinflammation is an important secondary injury process, though how it contributes to epileptogenesis, and the development of chronic, spontaneous seizure activity, remains poorly understood...

BACKGROUND: Research about termination for fetal abnormality (TFA) suggests that it is a traumatic event with potential negative psychological consequences. However, evidence also indicates that following traumatic events individuals may experience growth. Although TFA's negative psychological outcomes are well documented, little is known of the potential for growth following this event. Therefore, the study's objectives were to measure posttraumatic growth (PTG) post-TFA, examine the relationship between PTG, perinatal grief and coping, and determine the predictors of PTG...

PURPOSE: Post-traumatic growth (PTG) can occur following acquired brain injury (ABI). It has been proposed that people experiencing psychological distress following ABI may benefit from a positive psychotherapy intervention (PPT) aimed at increasing well-being; PPT may also influence PTG. We aimed to investigate PTG experiences in participants of a positive psychotherapy pilot trial. METHODS: ABI survivors who had received PPT or treatment as usual (TAU) were interviewed individually after the end of the trial...

Starting from the challenge offered by the authors of the post-traumatic growth (PTG) construct (Tedeschi & Calhoun, ), this paper aims to explore the existence of different linguistic profiles of cognitive and emotional processes in PTG narratives. The autobiographical narratives of 40 cancer patients were analysed for both PTG and linguistic indicators of emotions and cognitive processes. PTG was operationalised as the presence of redemption sequences (McAdams, ). The emotional and cognitive linguistic indicators were analysed by the LIWC program (Pennebaker & Francis, )...

A traumatic and/or degenerative meniscus lesion is thought to be a clinical manifestation of early-onset osteoarthritis (OA), which is a chronic progressive condition that can cause substantial pain and disability. Platelet-rich plasma (PRP) is an emerging treatment option that has been reported to improve healing. Here, we present a case of a 29-year-old woman, with left anterior and medial knee pain, without history of trauma or injury. The patient was managed with leukocyte-poor PRP injections derived from her peripheral blood with high concentrations of platelets, platelet-derived growth factors, and bioactive proteins, with a total follow-up of 30 months...

OBJECTIVES: Administration of sodium selenate to rats given traumatic brain injury (TBI) attenuates brain damage and improves long-term behavioural outcomes. We have previously provided evidence that TBI causes bone loss in rats, however the effect of sodium selenate treatment on bone quantity following TBI is unknown. METHODS: Rats were randomly assigned into sham injury or fluid percussion injury (FPI) groups and administered saline or sodium selenate for 12 weeks post-injury...

Traumatic brain injury (TBI) represents a critical health problem of which diagnosis, management, and treatment remain challenging. TBI is a contributing factor in approximately one-third of all injury-related deaths in the United States. The Centers for Disease Control and Prevention estimate that 1.7 million people suffer a TBI in the United States annually. Efforts continue to focus on elucidating the complex molecular mechanisms underlying TBI pathophysiology and defining sensitive and specific biomarkers that can aid in improving patient management and care...

BACKGROUND: Little is known about posttraumatic stress (PTS) reactions in bereaved individuals following loss in disaster who were not directly exposed to disaster. The aim of the present study was to examine the course of PTS up to three years after losing relatives in the MS Estonia ferry disaster, one of the worst maritime disasters in modern times. METHODS: Seven postal surveys were sent out over three years post-disaster. The respondents were invited and added consecutively during the three years and 938 relatives participated in one or more of the surveys, representing 89% of the MS Estonia's Swedish victims...
