Liposomal CBD (20 mg/day) was as effective as the highest dose of non-liposomal CBD (50 mg/day) in improving clinical outcomes. Hematocrit, comprehensive metabolic profile, and clinical chemistry indicated no significant detrimental impact of CBD administration over the four-week analysis period. This study supports the safety and therapeutic potential of hemp-derived CBD for relieving arthritic pain and suggests follow-up investigations in humans is warranted.Immersive Virtual Reality (VR) consists of immersion in artificial environments through the use of real-time render technologies and the latest generation devices. The users feel just as immersed as they would feel in an everyday life situation and this sense of presence appears to have therapeutic potentials. However, the VR mechanisms remain only partially known. This study is novel in that, for the first time in VR research, appropriate controls for VR contexts, immersive characteristics (i.e. control VR), and multifaceted objective and subjective outcomes were included in a within-subjects study design conducted on healthy participants.Participants received heat thermal stimulations to determine how VR can increase individual heat-pain tolerance limits (primary outcome) measured in degrees Celsius and seconds while recording concurrent autonomic responses. We also assessed changes in pain unpleasantness, mood, situational anxiety, and level of enjoyment (secondary outcomes).The VR induced a net gain in heat-pain tolerance limits that was paralleled by an increase of the parasympathetic responses. VR improved mood, situational anxiety and pain unpleasantness when participants perceived the context as enjoyable but these changes did not influence the increases in pain tolerance limits. Distraction increased pain tolerance limits but did not induce such mood and physiological changes.Immersive VR has been anecdotally applied to improve acute symptoms in contexts like battlefield, emergency and operating rooms. This study provides a mechanistic framework for VR as a low-risk, non-pharmacological intervention which regulates autonomic, affective (mood and situational anxiety) and evaluative (subjective pain and enjoyment ratings) responses associated with acute pain.Mixed lineage leukemia 1 (MLL1)-mediated histone H3 lysine 4 trimethylation (H3K4me3) of a subset of genes has been linked to the transcriptional activation critical for synaptic plasticity, but its potential contribution to neuropathic allodynia development remains poorly explored. Here, we show that MLL1, which is induced in dorsal horn neuron after spinal nerve ligation (SNL), is responsible for mechanical allodynia and increased H3K4me3 at metabotropic glutamate receptor subtype 5 (mGluR5) promoter. Moreover, SNL induced WD (Trp-Asp) repeat domain 5 subunit (WDR5) expression as well as the MLL1-WDR5 interaction accompany with H3K4me3 enrichment and transcription of mGluR5 gene in the dorsal horn in neuropathic allodynia progression. Conversely, WDR5-0103, a novel inhibitor of the MLL1-WDR5 interaction, reversed SNL-induced allodynia and inhibited SNL-enhanced mGluR5 transcription/expression as well as MLL1, WDR5, and H3K4me3 at the mGluR5 promoter in the dorsal horn. Furthermore, disrupting the expression of MLL1 or WDR5 using siRNA attenuated mechanical allodynia and reversed protein transcription/expression and complex localizing at mGluR5 promoter in the dorsal horn induced by SNL. This finding revealed that MLL1-WDR5 complex integrity regulates MLL1 and WDR5 recruitment to H3K4me3 enrichment at mGluR5 promoterin the dorsal horn underlying neuropathic allodynia. Collectively, our findings indicated that SNL enhances the MLL1-WDR5 complex, which facilitates MLL1 and WDR5 recruitment to H3K4me3 enrichment at mGluR5 promoter in spinal plasticity contributing to neuropathic allodynia pathogenesis.This paper is the first to present the Graphical Index of Pain (GRIP), a new user-friendly web-based method for high throughput screening of pain. The long-term goal of the method is to improve global standardization of pain measurements. GRIP consists of a hierarchical body map with ten first-tier body regions, and a second tier with multiple pain loci (167 among men, 168 among women), which provides detailed information about pain location and distribution. Follow-up questions for first tier regions include the following pain characteristics onset, episode frequency, episode duration (including constant pain), intensity, suffering, depth of pain, and effects on sleep and daily activities. The first implementation of GRIP was in the Tromsø Study (2015-2016), a population based study of adults aged 40-99. In total, 21,083 individuals participated in the study and ninety-six percent (n=20,263; age 40-96) completed GRIP. Pain intensity at first-tier regions and pain location and distribution at second-tier regions are in this paper presented by sex stratified customized heat maps showing large sex difference. Mean time to mark the first- and second-tier regions was 74 seconds. In conclusion, GRIP allows high-resolution assessment and presentation of pain location and distribution with minimal use of time.In the current climate of increased global terrorism, the threat of a radiological incident is becoming more realistic than ever, and as such, the necessity of early-warning detection is paramount to national security. To assist with this need, we have investigated the detection of uncharged particle emissions from radiological sources using charged-coupled devices (CCDs), which are contained within a variety of products, including consumer cellphones and traffic cameras. Because the CCD is intrinsically sensitive to charge accumulation as a result of linear energy transfer by the incident particles, each event can be counted and quantified using video-image processing and an estimated energy band assessed by the properties of the pixels. In an effort to make this process applicable to the widest possible range of CCDs available, this experiment was conducted using low-quality CCDs contained within consumer-grade, budget web cameras. Within a Pu-Be neutron howitzer, particles were detected using several camera models Gigaware X76, Z76 and Logitech C170, C270. Particle detection events were counted by post-processing with Matlab, and an efficiency for each CCD was determined relative to both a theoretical flux model and a calibrated He tube detector. The relative detection efficiencies for the cameras tested fell within the range 14-18% and showed a linear correlation between incident energy and pixel response.Recidivism is a key outcome measure for injury prevention programs. Firearm injury recidivism rates are difficult to determine due to poor longitudinal follow-up and incomplete, disparate databases. Reported recidivism rates from trauma registries are 2-3%. We created a collaborative database merging law enforcement, emergency department, and inpatient trauma registry data to more accurately determine rates of recidivism in patients presenting to our trauma center following firearm injury. METHODS A collaborative database for Jefferson County, Kentucky was constructed to include violent firearm injuries encountered by the trauma center or law enforcement from 2008 to 2019. Iterative deterministic data linkage was utilized to create the database and eliminate redundancies. From patients with at least one hospital encounter, raw recidivism rates were calculated by dividing the number of patients injured at least twice by the total number of patients. Cox proportional hazard models were used to evaluate risk facng rates as high as 26%. LEVEL OF EVIDENCE III, Retrospective Review.Non-compressible torso hemorrhage in trauma is particularly lethal. Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) has the potential to stabilize these patients, but currently is contraindicated for major thoracic bleeding. The goal of this study was to evaluate the effect of REBOA on the hemodynamic and metabolic profile as well as its effect on early survival in a porcine model of thoracic hemorrhage and shock. METHODS Forty-eight (48) male Yorkshire swine (60-80kg) underwent 30% hemorrhage and were randomized to three thoracic injuries, with and without Zone 1 REBOA occlusion pulmonary parenchymal injury (PI), thoracic venous injury (VI), or subclavian artery injury (AI). Following hemorrhage, thoracic injuries were induced (T0) and allowed to bleed freely. REBOA groups had Zone 1 occlusion after the thoracic injury, with deflation at T30. All groups had whole blood resuscitation at T30 and were euthanized at T90. Survival, total blood loss, mean arterial pressure (MAP), end tidal CO2 (EtCO2), and arterial blood gas parameters were analyzed. Statistical significance was determined by t-tests and two-way repeated measures ANOVA. RESULTS The use of REBOA improved the hemodynamics in all three injury patterns, with no differences observed in the outcomes of short-term survival and thoracic blood loss between the REBOA and non-REBOA groups. All groups showed equivalent changes in markers of shock (pH, HCO3, and Base Excess) prior to resuscitation. CONCLUSION In this animal study of hemorrhage and major thoracic bleeding, the addition of Zone 1 REBOA did not significantly affect short-term survival or blood loss, while providing hemodynamic stabilization. Therefore in non-compressible thoracic bleeding, without immediate surgical capability, long-term outcomes may be improved with REBOA, and thoracic hemorrhage should not be considered contraindications to REBOA use. LEVEL OF EVIDENCE Level I Therapeutic/Care Management Study.This article reviews four emerging endovascular hemorrhage control and extracorporeal perfusion techniques for management of trauma patients with profound hemorrhagic shock including hemorrhage-induced traumatic cardiac arrest. These include resuscitative endovascular balloon occlusion of the aorta (REBOA), selective aortic arch perfusion (SAAP), extracorporeal life support (ECLS), and emergency preservation and resuscitation (EPR). The pre-clinical and clinical studies underpinning the use of each of these techniques are summarized. We also present an integrated conceptual framework for how these emerging technologies may be used in the future care of trauma patients in both resource-rich and austere environments. LEVEL OF EVIDENCE N/A.Radiographic imaging is critical in helping guide treatment of critically injured patients. CID-1067700 Cone beam computed tomography (CBCT) is an axial imaging technique available from fixed imaging systems found in hybrid operating rooms. CBCT can be used to provide focused studies of specific anatomical regions, where patients cannot undergo conventional multi-detector CT. This includes non-contrast enhanced evaluation of the intra-cranial contents and vascular imaging throughout the body. There are a number of advantages and disadvantages to CBCT, but these are not widely discussed within the trauma literature. This narrative review article presents the initial practical experience of this novel imaging modality.Review Article LEVEL OF EVIDENCE Level III.Cervical carotid artery injuries entail high morbidity and mortality and are technically challenging to repair. This retrospective study describes the management and outcomes of cervical carotid injuries sustained during the recent wars in Iraq and Afghanistan. METHODS The Department of Defense Trauma Registry was queried to identify U.S. military personnel who sustained battle-related cervical carotid injury between January 2002 and December 2015. Retrospective chart reviews of the military Electronic Health Record were performed on patients identified. Demographics, injury characteristics, surgical management, and outcomes were reviewed. Statistical analysis was performed to identify associations between injury and management factors, as well as stroke and mortality. RESULTS In total, 67 patients (100% male; age 25±7 years) were identified with cervical carotid artery injuries. Fifty-six (84%) patients sustained a common (CCA) or internal carotid (ICA) injury and 11 (16%) patients had an isolated external (ECA) injury.
