BACKGROUND: Penetrating trauma kills rapidly. Thorough and efficient examination and aggressive hemorrhage control is important to save lives. The aim of this study was to assess the skills of civilian Emergency Medical Technicians (EMTs) in bleeding examination and control compared to Army Medics. Our hypothesis was that civilian pre-hospital systems perform at a lower level compared to an expert group, and did not have sufficient focus on education and training in examination and treatment of penetrating injuries...

Inflammatory bowel disease (IBD) is a devastating disease that is associated with excessive inflammation in the intestinal tract in genetically susceptible individuals and potentially triggered by microbial dysbiosis. This illness markedly predisposes patients to thrombophilia and chronic debility as well as bowel, lymphatic, and liver cancers. Development of new therapies is needed to re-establish long-term immune tolerance in IBD patients without increasing the risk of opportunistic infections and cancer...

We have previously reported that the topical application of erythropoietin (EPO) to cutaneous wounds in rats and mice with experimentally-induced diabetes mellitus (DM) accelerates their healing by stimulating angiogenesis, reepithelialization, and collagen deposition, and suppressing the inflammatory response and apoptosis. Aquaporins (AQP) are integral membrane proteins whose function is to regulate intracellular fluid hemostasis by enabling the transport of water and glycerol. AQP3 is the AQP that is expressed in the skin where it facilitates cell migration and proliferation and reepithelialization during wound healing...

OBJECTIVE: Vascular closure devices have been used to achieve hemostasis of percutaneous access sites following endovascular procedures, with reported decreased time for arterial control as well as decreased time to ambulation. We sought to determine rates and risk factors of postoperative bleeding complications and failures using these devices from a single institution experienced in the use of vascular closure devices. METHODS: All patients undergoing arterial endovascular procedures with percutaneous access between March 2010 and October 2015 at a single institution were identified and analyzed (n=894)...

Post-endoscopic sphincterotomy bleeding is a common complication of biliary sphincterotomy, and the incidence varies from 1% to 48%. It can be challenging to localize the bleeder or to administer various interventions through a side-viewing endoscope. This study aimed to evaluate the risk factors of post-endoscopic sphincterotomy bleeding and the outcome of endoscopic intervention therapies. We retrospectively reviewed the records of 513 patients who underwent biliary sphincterotomy in Mackay Memorial Hospital between 2011 and 2016...

BACKGROUND: Patients on warfarin who present with bleeding or who require an urgent procedure are commonly treated with intravenous (IV) vitamin K, which is supplemented with repletion of the vitamin K factors using either plasma or a prothrombin complex concentrate (PCC). In some such cases, use of vitamin K alone could be adequate to achieve acceptable hemostasis. STUDY DESIGN AND METHODS: An algorithm emphasizing the use of vitamin K alone in patients presenting with non-life-threatening bleeding was encouraged, with repeat testing of the international normalized ratio (INR) within 5 hours...

Dengue is the most prevalent human arbovirus disease worldwide. Dengue virus (DENV) infection causes syndromes varying from self-limiting febrile illness to severe dengue. Although dengue pathophysiology is not completely understood, it is widely accepted that increased inflammation plays important roles in dengue pathogenesis. Platelets are blood cells classically known as effectors of hemostasis which have been increasingly recognized to have major immune and inflammatory activities. Nevertheless, the phenotype and effector functions of platelets in dengue pathogenesis are not completely understood...

In the absence of a specific laboratory test of envenomation, there is a need for an alternative mechanism for the early recognition of envenomation following hematotoxic snake-bite in tropical countries. Abnormalities of clotting are commonly associated with hematotoxic snake bite either due to systemic envenomation or due to the release of an inappropriate tourniquet applied as 'first-aid' often by the rural people before presentation to the hospital. Thromboelastography (TEG) has been used to monitor the coagulation abnormalities in various clinical scenarios...

Adipose tissue is a complicated organ that not only stores excess energy, but also secrets many adipokines regulating whole-body energy hemostasis. Dysfunction of adipose tissue leads to metabolic disorders such as insulin resistance, hypertension, cardiovascular diseases. In this study, we generated a mouse model with overexpression of Angiotensin II type 1 receptor-associated protein (ATRAP) in adipose tissue specifically. Under a normal diet, ATRAP transgene (TgATRAP) mice showed similar bodyweight, fat mass and insulin sensitivity with wild-type controls (WT)...

BACKGROUND: Patients who suffer a cardiac arrest from trauma rarely survive, even with aggressive resuscitation attempts, including an Emergency Department (ED) thoracotomy. Emergency Preservation and Resuscitation (EPR) was developed to utilize hypothermia to buy time to obtain hemostasis before irreversible organ damage occurs. Large animal studies have demonstrated that cooling to tympanic membrane temperature 10°C during exsanguination cardiac arrest can allow up to 2 hours of circulatory arrest and repair of simulated injuries with normal neurologic recovery...

Platelet adhesion and aggregation, coagulation, fibrin formation, and fibrinolysis are regulated by the forces and flows imposed by blood at the site of a vascular injury. Flow chambers designed to observe these events are an indispensable part of doing hemostasis and thrombosis research, especially with human blood. Microfluidic methods have provided the flexibility to design flow chambers with complex geometries and features that more closely mimic the anatomy and physiology of blood vessels. Additionally, microfluidic systems with integrated optics and/or pressure sensors and on-board signal processing could transform what have been primarily research tools into clinical assays...

Controlling massive hemorrhage is of great importance to lower transfusional medical cost, and to reduce death and mobility rate in battlefield and civilian accidents. We reported the fabrication of porous chitosan microspheres (CSMS) with tunable surface pore size by microemulsion combined with thermally induced phase separation technique, and its application as a quick hemostat. Their hemostatic property was characterized by blood clotting kinetics, adherence interaction between red blood cells/platelets and CSMS, in vitro and in vivo hemostasis by rat tail amputation and liver laceration models, and histological analysis...

Hemostasis is the process of sealing a vascular injury with a thrombus to arrest bleeding. The type of thrombus that forms depends on the nature of the injury and hemodynamics. There are many models of intravascular thrombus formation whereby blood is exposed to prothrombotic molecules on a solid substrate. However, there are few models of extravascular thrombus formation whereby blood escapes into the extravascular space through a hole in the vessel wall. Here, we describe a microfluidic model of hemostasis that includes vascular, vessel wall, and extravascular compartments...
