BACKGROUND: Despite improvements in the management of severely injured patients, development of multiple organ dysfunction syndrome (MODS) remains a morbid complication of traumatic shock. One of the key attributes of MODS is a profound bioenergetics crisis, for which the mediators and mechanisms are poorly understood. We hypothesized that metabolic uncoupling using an experimental phosphoinositol-3 kinase (PI3-K) inhibitor, LY294002 (LY), may prevent mitochondrial abnormalities that lead to the generation of mitochondrial DNA (mtDNA) damage and the release of mtDNA damage-associated molecular patterns (DAMPs)...

BACKGROUND: Often the clinician is faced with a diagnostic and therapeutic dilemma in patients with concomitant traumatic brain injury (TBI) and hemorrhagic shock (HS), as rapid deterioration from either can be fatal. Knowledge about outcomes after concomitant TBI and HS may help prioritize the emergent management of these patients. We hypothesized that patients with concomitant TBI and HS (TBI + HS) had worse outcomes and required more intensive care compared with patients with only one of these injuries...

BACKGROUND: During traumatic hemorrhage, the ability to identify shock and intervene before decompensation is paramount to survival. Lactate is extremely sensitive to shock, and its clearance has been demonstrated a useful gauge of shock and resuscitation status. Though lactate can be measured in the field, logistical constraints render it impractical in certain environments. The compensatory reserve represents a new clinical measurement reflecting the remaining capacity to compensate for hypoperfusion...

Background: Femoral shaft fractures, typical in younger people, are often associated with polytrauma followed by traumatic shock. In these situations, despite intramedullary nailing being the treatment of choice, external fixation could be used as the definitive treatment. The aim of this study is to report evidence regarding definitive treatment of femoral shaft fractures with monoaxial external fixation. Methods: Between January 2006 and December 2015, 83 patients with 87 fractures were treated at the Department of Orthopaedics and Traumatology CTO of Turin, with a monoaxial external fixation device...

Anxiety disorders are the most common mental health disorders, and daily transient feelings of anxiety (or "stress") are ubiquitous. However, the precise impact of both transient and pathological anxiety on higher-order cognitive functions, including short- and long-term memory, is poorly understood. A clearer understanding of the anxiety-memory relationship is important as one of the core symptoms of anxiety, most prominently in post-traumatic stress disorder (PTSD), is intrusive reexperiencing of traumatic events in the form of vivid memories...

Background -Out-of-hospital cardiac arrest (OHCA) commonly presents with non-shockable rhythms (asystole and pulseless electrical activity (PEA)). Whether antiarrhythmic drugs are safe and effective when these evolve to shockable rhythms (ventricular fibrillation/pulseless ventricular tachycardia (VF/VT)) during resuscitation is not known. Methods -Adults with non-traumatic OHCA, vascular access and VF/VT anytime after ≥1 shock(s) were prospectively randomized, double-blind, to receive amiodarone, lidocaine or placebo by paramedics...

The locus coeruleus (LC)-amygdala circuit is implicated in playing a key role in responses to emotionally arousing stimuli and in the manifestation of post-traumatic stress disorder (PTSD). Here, we examined changes in gene expression of a number of important mediators of the LC-amygdala circuitry in the inhibition avoidance model of PTSD. After testing for basal acoustic startle response (ASR), rats were exposed to a severe footshock (1.5 mA for 10 s) in the inhibitory avoidance apparatus. They were given contextual situational reminders every 5 day for 25 days...

BACKGROUND: Standard cardiopulmonary resuscitation (CPR) is ineffective in treating traumatic cardiac arrest (TCA) following hemorrhagic shock despite fluid resuscitation. CPR adjuncts, including abdominal compressions and external counter pressure, have shown some success in laboratory settings. The Abdominal Aortic and Junctional Tourniquet (AAJT) is a device that occludes both venous and arterial blood at the level of the aortic bifurcation and likely increases thoracic pressure when applied to the abdomen...

BACKGROUND: Endothelial cell damage and glycocalyx shedding following trauma can increase the risk of inflammation, coagulopathy, vascular permeability and death. Bedside sublingual video-microscopy may detect worse flow and perfusion associated with this endotheliopathy. We compared markers of endotheliopathy with physical flow dynamics following traumatic hemorrhagic shock (THS). METHODS: Sublingual incident dark field video-microscopy was performed at three time-points following injury (<10h; 10-30h; and 30-50h)...

Traumatic brain injury (TBI) due to blast from improvised explosive devices has been a leading cause of morbidity and mortality in recent conflicts in Iraq and Afghanistan. However, the mechanisms of primary blast-induced TBI are not well understood. The Akt signal transduction pathway has been implicated in various brain pathologies including TBI. In the present study, the effects of simulated primary blast waves on the phosphorylation status of Akt and its downstream effector kinase, glycogen synthase kinase 3β (GSK3β), in rat hippocampus, were investigated...

This study reports the case of an acoustic shock injury (ASI), which did not result in a significant hearing loss, but was followed by manifold chronic symptoms both within (tinnitus, otalgia, tingling in the ear, tension in the ear, and red tympanum) and outside the ears (blocked nose, pain in the neck/temporal region). We suggest that these symptoms may result from a loop involving injury to middle ear muscles, peripheral inflammatory processes, activation and sensitization of the trigeminal nerve, the autonomic nervous system, and central feedbacks...

BACKGROUND: Traumatic shock cannot be diagnosed by a single physiological measurement and a number of vital sign based combined shock scores (CSS) have been proposed to identify and triage trauma patients with shock. This audit uses data from a prospectively entered electronic trauma registry to compare the ability of these CSS to predict in-hospital mortality, need for surgery, need for blood transfusion and ICU admission. MATERIALS AND METHODS: The data used in the study was obtained from the Hybrid Electronic Medical Record (HEMR) in Pietermaritzburg from January 2012-September 2015...

PURPOSE: Evidence suggests that trauma patients with hemorrhagic shock requiring massive transfusion have improved outcomes if resuscitated with a prescribed massive transfusion protocol (MTP). However, there is limited data regarding the efficacy of MTP in non-trauma patients. METHODS: This was a retrospective observational study of all patients who received a massive transfusion protocol for non-traumatic hemorrhagic shock over a four-year period. The primary outcome was in-patient hospital survival...

PURPOSE OF REVIEW: To describe how hemostatic resuscitation can be used in the prehospital phase of resuscitation to reduce preventable deaths after traumatic injury. RECENT FINDINGS: Hemorrhagic shock is the leading cause of death that is preventable after injury. The National Academy of Sciences, recently, recommended that achievement of zero preventable deaths after traumatic injury should be the goal of a national trauma system. In the United States, there are an estimated 25 000 preventable deaths per year in the prehospital phase of resuscitation because of traumatic hemorrhagic shock...

BACKGROUND: South Africa is reported to have the highest rate of sexual assault in the world with over 40% of cases occurring among children. Children who are sexually abused have support programmes and policies to assist them in coping, but there are no support programmes for mothers or caretakers. Caretakers need support for themselves and assisting them will incrementally benefit children under their care. Often mothers of these children experience shock, anger, disbelief and suffer secondary trauma such as depression and post-traumatic stress disorder (PTSD) following their children's sexual abuse disclosure and yet there are no guidelines for support to these mothers within North-West province (NWP)Objectives: The study seeks to develop guidelines for support to mothers of sexually abused children in NWP...

Ample evidence demonstrates that fear learning contributes significantly to many anxiety pathologies including post-traumatic stress disorder (PTSD). The endocannabinoid (eCB) system may offer therapeutic benefits for PTSD and it is a modulator of the hypothalamic pituitary adrenal (HPA) axis. Here we compared the separated and combined effects of blocking glucocorticoid receptors (GRs) using the GR antagonist RU486 and enhancing CB1r signaling using the CB1/2 receptor agonist WIN55,212-2 in the CA1 and basolateral amygdala (BLA) on the consolidation of traumatic memory...

'I want to erase him from my memory,' she said, 'his eyes, his eyes staring at me … they are there every night, his hand … every night it hits me again and again …'. On the basis of these few words taken from the therapeutic work with Keltoum, the author reflects theoretically and clinically on the place of memory in a traumatism: a fixed memory, a 'frozen image', the signs of a traumatic compulsion to repeat, are the expressions of a process of psychic disorganization but also of a 'symbolized and symbolizing' memory anticipating a possible historicization of this memory, of a path, therefore, towards a resolution of the trauma resulting from a process of psychic integration and reorganization...
