Acute trauma can lead to life-long changes in susceptibility to psychiatric disease, such as Post-Traumatic Stress Disorder (PTSD). Rats given free access to a concentrated glucose solution for 24 hours beginning immediately after trauma failed to show stress-related pathology in the learned helplessness model of PTSD and comorbid major depression. We assessed effective dosing and temporal constraints of the glucose intervention in three experiments. We exposed 120 male Sprague-Dawley rats to 100, 1 mA, 3-15s, inescapable and unpredictable electric tail shocks (over a 110 minute period) or simple restraint in the learned helplessness procedure...

Trauma is responsible for a large proportion of the world's burden of disease, and is by far the biggest killer of young adults. Haemorrhage is the leading cause of preventable death and its effects are directly correlated with the incidence multi-organ failure in survivors. Trauma research is challenging due to patient heterogeneity, limited randomised controlled trials, and in vitro studies that fail to mimic the systemic injury response. Preclinical research remains essential for mechanistic and therapeutic discovery...

Fear conditioning studies in rodents allow us to assess vulnerability factors which might underlie fear-based psychopathology such as post-traumatic stress disorder (PTSD). Despite PTSD being more prevalent in females than males, very few fear conditioning studies in rodents have tested females. Our study assessed fear conditioning and extinction in male and female rats using both fear-potentiated startle and freezing behavior as measures. Rats were trained to fear cues that predicted the occurrence of shock and then subsequently exposed to an extinction training procedure where the cue was presented repeatedly in the absence of shock...

To date, there are no reviews on machine learning (ML) for predicting outcomes in trauma. Consequently, it remains unclear as to how ML-based prediction models compare in the triage and assessment of trauma patients. The objective of this review was to survey and identify studies involving ML for predicting outcomes in trauma, with the hypothesis that models predicting similar outcomes may share common features but the performance of ML in these studies will differ greatly. MEDLINE and other databases were searched for studies involving trauma and ML...

BACKGROUND: Valproic acid, a histone deacetylase inhibitor, has beneficial effects in the setting of cancer, neurologic diseases, and traumatic injuries. In animal models of traumatic injury, a single dose of valproic acid has been shown to reduce mortality. The purpose of this trial was to determine the maximum tolerated single dose of intravenous valproic acid in healthy humans. METHODS: A double-blinded, placebo-controlled, dose-escalation trial design was used to identify dose-limiting toxicities in healthy subjects who received a single dose of intravenous valproic acid...

REVIEW
Pierrick Disdier
The post-traumatic nightmare is the reliving of traumatic scenes during sleep and is linked to post-traumatic stress disorder. Unlike other forms of dreams, it can happen at any stage of sleep, invasively, and makes the person relive their traumatic scenario, which can plunge them into a state of terror and shock. Post-traumatic nightmares thereby maintain and reactivate the traumatic memory. However, narration techniques can lead to a marked improvement and even the disappearance of these nightmares.

A combination of antidepressant drugs and psychotherapy exhibits more promising efficacy in treating fear disorders than either treatment alone, but underlying mechanisms of such treatments remain largely unknown. Here we investigated the role of DNA methylation of the brain-derived neurotrophic factor (Bdnf) gene in the therapeutic effects of ketamine in combination with extinction training in a mouse model of post-traumatic stress disorder (PTSD) induced by inescapable electric foot shocks (IFS). Male mice received ketamine for 22 consecutive days starting 1 h after the IFS (long-term ketamine treatment) or 2 h prior to the extinction training on days 15 and 16 after the IFS (short-term ketamine treatment)...

Avoiding associatively learned predictors of danger is crucial for survival. Aversive memories can, however, become counter-adaptive when they are overly generalized to harmless cues and contexts. In a fruit fly odor-electric shock associative memory paradigm, we found that learned avoidance lost its specificity for the trained odor and became general to novel odors within a day of training. We discuss the possible neural circuit mechanisms of this effect and highlight the parallelism to over-generalization of learned fear behavior after an incubation period in rodents and humans, with due relevance for post-traumatic stress disorder...

This study is a report on a case of papillary carcinoma of the kidney revealed by an abdominal contusion. The results of radiological investigations were discordant with the low intensity of the shock. The treatment consisted of radical nephrectomy because of the suspicion of a pre-existing malignancy. Histological analysis revealed a papillary carcinoma pT3N0M0. We focus on the need for performing diagnostic tests in order to avoid missing a pre-existing anomaly to the kidney trauma.

BACKGROUND: Although coagulopathy can be very common in severe traumatic shock patients, the exact incidence and mechanism remain unclear. In this study, a traumatic shock rabbit model with special abdomen injuries was developed and evaluated by examining indicators of clotting and fibrinolysis. METHODS: Forty New Zealand white rabbits were randomly divided into four groups: group 1 (sham), group 2 (hemorrhage), group 3 (hemorrhage-liver injury), and group 4 (hemorrhage-liver injury/intestinal injury-peritonitis)...

BACKGROUND: Severe traumatic injury is associated with bone marrow dysfunction that manifests as impaired erythropoiesis and prolonged hematopoietic progenitor cell (HPC) mobilization from the bone marrow. Extramedullary erythropoiesis, the development of red blood cells outside the bone marrow, has not been studied following severe injury and critical illness. This study examined the influence of lung contusion/hemorrhagic shock (LCHS) followed by chronic stress (CS) on the rodent spleen and to investigate the involvement of the splenic erythropoietin/erythropoietin receptor and BMP4 signaling...

OBJECTIVES: Despite clinical reports of poor outcomes, the degree to which REBOA exacerbates traumatic brain injury (TBI) is not known. We hypothesized that combined effects of increased proximal mean arterial pressure (pMAP), carotid blood flow (Qcarotid), and intracranial pressure (ICP) from REBOA would lead to TBI progression compared to partial aortic occlusion (PAO) or no intervention. METHODS: 21 swine underwent a standardized TBI via computer Controlled cortical impact followed by 25% total blood volume rapid hemorrhage...

BACKGROUND: Non-compressible hemorrhage of the torso remains a challenging surgical dilemma. Stent graft repair requires endovascular expertise, imaging, and inventory that are not available within the critical window of massive hemorrhage. We developed a retrievable stent graft for rapid hemorrhage. We further investigated a radiofrequency (RF) positioning approach as a possible alternative to the logistics of fluoroscopy. METHODS: A retrievable stent graft was constructed with a novel "petal and stem" design from nitinol and covered with a sleeve of electrospun polyurethane...

BACKGROUND: Despite previous evidence for a potent inflammatory response after a traumatic brain injury (TBI), it is unknown whether exercise preconditioning (EP) improves outcomes after a TBI by modulating inflammatory responses. METHODS: We performed quantitative real-time PCR (qPCR) to quantify the genes encoding 84 cytokines and chemokines in the peripheral blood and used ELISA to determine both the cerebral and blood levels of interleukin-6 (IL-6). We also performed the chromatin immunoprecipitation (ChIP) assay to evaluate the extent of nuclear factor kappa-B (NF-κB) binding to the DNA elements in the IL-6 promoter regions...

Trauma-induced acute kidney injury (AKI), such as after hemorrhagic shock (HS) or burn, remains a significant problem in the intensive care unit and is associated with increased mortality. The pathophysiology that drives AKI post-trauma is multi factorial, and includes both inflammatory and metabolic alterations. Identifying the systemic profile that contributes to AKI is crucial not only for early diagnosis, but also for identifying treatments that improve kidney function and maintaining long-term patient health...

The priority in the management of patients with traumatic hemorrhagic shock is to control the bleeding with simultaneous volume resuscitation to maintain adequate tissue perfusion. Fluid replacement remains the mainstay of initial resuscitation in hemorrhagic shock. Traditionally, vasopressors are contraindicated in the early management of hemorrhagic shock due to their deleterious consequences, although vasopressors may have a role in resuscitation when vasoplegic shock ensues and blood pressure cannot be maintained by fluids alone...

Heat shock proteins (HSPs) mediate a diverse range of cellular functions, prominently including folding and regulatory processes of cellular repair. A major property of these remarkable proteins, dependent on intracellular or extracellular location, is their capacity for immunoregulation that optimizes immune activity while avoiding hyperactivated inflammation. In this review, recent investigations are described, which examine roles of HSPs in protection of kidney tissue from various traumatic influences and demonstrate their potential for clinical management of nephritic disease...

BACKGROUND: Hemorrhage is a major cause of early mortality following a traumatic injury. The progression and consequences of significant blood loss occur quickly as death from hemorrhagic shock or exsanguination often occurs within the first few hours. The mainstay of treatment therefore involves early identification of patients at risk for hemorrhagic shock in order to provide blood products and control of the bleeding source if necessary. The intended scope of this review is to identify and assess combinations of predictors informing therapeutic decision-making for clinicians during the initial trauma assessment...
