Objective Alveolar macrophages play a key role in the development and resolution of acute respiratory distress syndrome (ARDS), modulating the inflammatory response and the coagulation cascade in lungs. Anti-coagulants may be helpful in the treatment of ARDS. This study investigated the effects of nebulized heparin on the role of alveolar macrophages in limiting lung coagulation and inflammatory response in an animal model of acute lung injury (ALI). Methods Rats were randomized to four experimental groups...

BACKGROUND: The optimal management of minor head injured patients with brain injury identified by CT imaging is unclear. Some guidelines recommend routine hospital admission of GCS13-15 patients with traumatic brain (TBI) injury identified by CT imaging. Others argue that selected lower-risk patients can be discharged from the Emergency Department (ED). OBJECTIVE: To estimate the risk of death, neurosurgery and clinical deterioration minor head injured patients with TBI identified by CT imaging, and assess which factors affect the risk of these outcomes...

Serotonin is an important neurotransmitter that plays a major role in the pathogenesis of a variety of conditions, including psychiatric disorders. The detection of serotonin typically relies on high-performance liquid chromatography (HPLC), an expensive technique that requires sophisticated equipment and trained personnel, and is not suitable for point-of-care applications. In this contribution, we introduce a novel sensor platform that can measure spiked neurotransmitter concentrations in whole blood samples in a fast and low-cost manner by combining synthetic receptors with a thermal readout technique-the heat-transfer method...

Aging is associated with a vasoconstrictive, pro-coagulant, and pro-inflammatory profile of arteries and a decline in the bioavailability of the endothelium-derived molecule nitric oxide. Dietary nitrate elicits vasodilatory, anti-coagulant and anti-inflammatory effects in younger individuals, but little is known about whether these benefits are evident in older adults. We investigated the effects of 140 mL of nitrate-rich (HI-NI; containing 12.9 mmol nitrate) versus nitrate-depleted beetroot juice (LO-NI; containing ≤0...

INTRODUCTION: Spontaneous perirenal hemorrhage (SPH) or Wunderlich syndrome, is a rare but potentially life-threatening condition. It is characterized by an unexpected bleeding in the kidneys and usually presents as an abdominal pain. Angiography and more recently selective renal arterial embolization are emerging as effective modalities for the diagnosis and treatment of SPH. In this article, we report a total of three cases of SPH in hemodialysis (HD) patients. METHODS: This is the experience of diagnosis and treatment of SPH in HD patients...

Thrombomodulin (TM), an endothelial protein with anti-coagulant activity, is composed of 5 domains, D1-D5. Recombinant human soluble TM (TMα) consisting of D1-D3, which is generated in CHO cells, suppresses inflammatory and nociceptive signals by inactivating high mobility group box 1 (HMGB1), one of damage-associated molecular patterns. TMα sequesters HMGB1 with the lectin-like D1 and promotes its degradation by thrombin binding to the EGF-like D2. We prepared TM's D123, D1 and D2 by the protein expression system of yeast, and evaluated their effects on HMGB1 degradation in vitro and on the allodynia caused by HMGB1 in distinct redox forms in mice in vivo...

BACKGROUND: Admitted patients who fall and injure themselves during an acute hospitalization incur increased costs, morbidity, and mortality, but little research has been conducted on identifying inpatients at high risk to injure themselves in a fall. Falls risk assessment tools have been unsuccessful due to their low positive predictive value when applied broadly to entire hospital populations. We aimed to identify variables associated with the risk of or protection against injurious fall in the inpatient setting...

BACKGROUND & AIMS: Vitamin K antagonists (VKAs) promote recanalization of portal vein thrombosis (PVT) in patients with cirrhosis. However, the benefit of PVT recanalization might be offset by major and minor bleeding associated with use of anti-coagulants. We evaluated harmful and beneficial effects of VKA in patients with PVT and cirrhosis. METHODS: We performed a retrospective study of 63 consecutive patients with cirrhosis given anti-coagulants for a first detection of non-neoplastic PVT from 2003 to 2015 in Italy...

Upshaw-Schulman syndrome (USS) is a thrombo-hemorrhagic disease caused by congenital deficiency of ADAMTS13 due to ADAMTS13 gene mutations. USS is characterized by repeated episodes of thrombocytopenia and microangiopathic hemolytic anemia that respond dramatically to infusions of fresh frozen plasma. There are two phenotypic expressions of USS: one is the early-onset type and the other, the late-onset type, is asymptomatic during childhood with the first bout of thrombotic thrombocytopenic purpura (TTP) developing after adolescence or during adulthood...

Daiki Hira, Tomohiro Terada
The human breast cancer resistance protein (BCRP/ABCG2) is an ATP-binding cassette efflux transporter that uses ATP hydrolysis to expel xenobiotics from cells, including anti-cancer medications. It is expressed in the gastrointestinal tract, liver, kidney, and brain endothelium. Thus, ABCG2 functions as a tissue barrier to drug transport that strongly influences the pharmacokinetics of substrate medications. Genetic polymorphisms of ABCG2 are closely related to inter-individual variations in therapeutic performance...

BACKGROUND: Upper extremity deep vein thrombosis (UEDVT) constitutes around 10% of all DVT, and can cause both pulmonary embolism (PE) and postthrombotic syndrome (PTS) in the arm. The incidence of secondary UEDVT is increasing due to widespread use of central venous catheters in patients with cancer and other chronic diseases. The safety and efficacy of using new direct acting oral anti coagulants (DOAC) in the treatment of UEDVT has not been systematically evaluated. Our aims were to evaulate efficacy, safety, and risk of recurrence of venous thromboembolism (VTE) during DOAC treatment in UEDVT patients...

OBJECTIVE: Spontaneous intracranial hemorrhage (ICH) is frequently managed in neurosurgery. Patients with durable mechanical circulatory support devices, including total artificial hearts (TAHs) and left ventricular assist devices (LVADs) are often encountered in the setting of ICH. While durable mechanical circulatory support devices have improved survival and quality of life for patients with advanced heart failure, ICH is one of the most feared complications following LVAD and TAH implantation...

BACKGROUND: Regional anticoagulation with citrate is the recommended first line treatment for patients receiving continuous renal replacement therapy (CRRT). There is wide variability in filter patency which may be due to differences in patient characteristics and local practice. It is also possible that citrate has effects on primary and secondary haemostasis, fibrinolysis and platelet function that are still unknown. The primary aim of the study is to describe the effect of citrate on coagulation and fibrinolysis pathways in both the patient and the haemodialysis circuit...
