Although primary prevention with antithrombotic therapy is widely used in this setting, its effectiveness is not well defined, and requires further investigation. The aim of this study was to evaluate the utility of MRI-detected ischemic brain lesions as a possible future outcome for randomized clinical trials in this patient population. METHODS This prospective observational study included 20 adult blunt trauma patients admitted to a level I trauma center with a screening neck CTA showing extracranial carotid or vertebral artery injury. All subjects lacked initial evidence of an ischemic stroke and were managed with antithrombotic therapy and observation, and then underwent brain magnetic resonance imaging (MRI) within 30 days of the injury to assess for ischemic lesions. The MRI scans included diffusion, susceptibility, and FLAIR sequences, and were reviewed by two neuroradiologists blinded to the CTA findinvel IV.We believe that the rapid and widespread adoption of REBOA as well as enthusiasm for catheter-based strategies has led to increased interest in basic endovascular techniques among trauma surgeons. The aim of this paper is to describe the most commonly performed endovascular procedures for trauma patients, the basic capital equipment and room set up, and a parsimonious inventory of disposable supplies needed to perform each procedure. Together these make a standardized trauma-specific endovascular inventory. LEVEL OF EVIDENCE AND STUDY TYPE V, economic/decision.BACKGROUND Extracellular cold-inducible RNA-binding protein (eCIRP) is a damage-associated molecular pattern (DAMP), which is released into the circulation after hemorrhagic shock (HS). Recently, we discovered that triggering receptor expressed on myeloid cells-1 (TREM-1) serves as a new receptor of eCIRP to exaggerate inflammation. Here, we hypothesize that by inhibiting the interaction between eCIRP and TREM-1 with the use of a novel short peptide derived from human eCIRP known as M3, we can inhibit the inflammatory response and acute lung injury (ALI) in HS. METHODS HS was induced using C57BL/6 mice by cannulating both femoral arteries. One femoral artery was used for removal of blood while the other was used for continuous monitoring of mean arterial blood pressure (MAP). The MAP of 25-30 mmHg was maintained for 90 min, followed by a resuscitation phase of 30 min with 1 mL of normal saline. The treatment group was given 10 mg/kg of M3 during the resuscitation phase. Four hours after resuscitation, serum and lungs were collected and analyzed for various injury and inflammatory markers by using colorimetry, real-time PCR, and ELISA. RESULTS There was an increase in the serum levels of tissue injury markers (ALT, AST, and LDH) as well as cytokines (TNF-α and IL-6) when comparing the vehicle group versus the sham group. This increase was significantly inhibited in the M3 treated group. The mRNA expression of pro-inflammatory cytokines TNF-α, IL-6, and IL-1β and the chemokines MIP-2 and KC in lungs was significantly increased in the vehicle-treated HS mice, while their expression was significantly decreased in M3-treated HS mice. Finally, M3 treatment significantly decreased the lung injury score compared to vehicle treated HS mice. CONCLUSION The novel eCIRP-derived TREM-1 antagonist (M3) can be a potential therapeutic adjunct in the management of hemorrhagic shock. STUDY TYPE Translational animal model.BACKGROUND Rib fractures in the geriatric trauma population are associated with significant morbidity and mortality. The outcomes of surgical stabilization of rib fractures (SSRF) have not been well defined in this population. METHODS Data from the 2016-2017 Trauma Quality Improvement Program (TQIP) database were analyzed. Patients greater than 65 years of age admitted with isolated chest wall injury and multiple rib fractures were abstracted from the database. Multivariate propensity score matching was utilized to stratify patients that underwent rib fixation versus nonoperative management. ARRY-382 supplier In the matched cohort, we assessed outcomes including mortality, intensive care unit (ICU) and hospital lengths of stay (LOS), tracheostomy rates, and ventilator-associated pneumonia (VAP) rates. We performed a secondary analysis of patients receiving early ( less then 72 hours) versus late SSRF. RESULTS Of the 44,450 patients included in the study analysis, 758 (1.7%) underwent SSRF. Patients undergoing SSRF were youngely SSRF may be associated with improved outcomes in the geriatric trauma population with multiple rib fractures. LEVEL OF EVIDENCE III, Therapeutic/Care management.BACKGROUND Mesenchymal stem/stromal cell (MSC) derived extracellular vesicles (EVs) are a possible cell-free alternative to MSCs because they retain the regenerative potential of MSCs, while still mitigating some of their limitations (such as the possible elicitation of host immune responses). The promotion and restoration of angiogenesis, however, is an important component in treating trauma related injuries, and has not been fully explored with EVs. Herein we describe the effects of monolayer adipose-derived EVs (MAd-EVs), spheroid adipose-derived EVs (SAd-EVs), monolayer bone marrow-derived EVs (MBM-EVs), and spheroid bone marrow-derived EVs (SBM-EVs) on human umbilical vein endothelial cell (HUVEC) tube formation and mitochondrial respiration. METHODS The successful isolation of EVs derived from adipose MSCs or bone marrow MSCs in monolayer or spheroid cultures was confirmed by NanoSight (particle size distribution) and Western blot (surface marker expression). EV angiogenic potential was measured using a 24-hour HUVEC tube formation assay. EV effects on HUVEC mitochondrial function were evaluated using the Seahorse respirometer machine. RESULTS The number of junctions, branches, and the average length of branches formed at 24 hours of tube formation were significantly affected by cell and culture type; overall adipose-derived EVs outperformed bone marrow-derived EVs, and spheroid-derived EVs outperformed monolayer-derived EVs. Additionally, adipose-derived EVs resulted in significantly increased HUVEC mitochondrial maximal respiration and adenosine triphosphate (ATP) production, while only MBM-EVs negatively impacted HUVEC proton leak. CONCLUSIONS Adipose-derived EVs promoted HUVEC tube formation significantly more than bone marrow-derived EVs, while also maximizing HUVEC mitochondria function. Results demonstrate that, as with MSC therapies, it is possible to tailor EV culture and production to optimize therapeutic potential.
