Abstract At present, methods for treating tertiary oil recovery wastewater via electro-coagulation are still in their early stage of development. In this study, a device for electro-coagulation wastewater treatment was built and tested in an oil field. The effects that the initial pH value, electrode type, and connection mode have on the coagulation and separation effect were assessed by measuring the mass fraction and turbidity of oil. The results have shown that when the electro-coagulation method is used, the effectiveness of the treatment can be significantly increased in neutral pH conditions (pH = 7), in acidic conditions, and More >

Abstract Introduction: Wallis et al (JAMA 2017) demonstrated use of antithrombotic medications (ATMs) is associated with increased prevalence of hematuria-related complications and subsequent bladder cancer diagnosis within 6 months. Stage of diagnosis was lacking in this highly publicized study. This study examined the association of ATM use on bladder cancer stage at the time of diagnosis.
Materials and methods: We completed a retrospective chart review of patients with a bladder cancer diagnosis at our institution. Patient demographics and bladder cancer work up information were assessed. Patients were stratified based on use of ATMs at time diagnosis. Descriptive statistics… More >

Abstract Gastric cancer is the fifth most commonly diagnosed cancer and the fourth leading cause of cancer death worldwide in 2020. Gastric cancer usually undergoes lymph node metastasis and implantation metastasis, but bone metastasis and bone marrow invasion are rare. However, gastric cancer patients with bone marrow invasion usually have cancer emergency, so special attention should be paid in clinical practice. Herein, we analyzed the clinical characteristics of an asian gastric cancer patient with bone marrow invasion and disseminated intravascular coagulation (DIC) in our hospital and summarized the diagnosis and treatment experience to provide a reference More >

Abstract Background: Thromboembolic events are a cause of significant morbidity and mortality in the Fontan population. We previously reported on coagulation profile changes in a cohort of patients with hypoplastic left heart syndrome (HLHS) from Stage I through Fontan completion. In this report, we examine their clinical status, anticoagulation and incidence of thromboembolic events up to 20 years post Fontan. Methods: A retrospective chart review was conducted for twenty (20) surviving patients, from 1998 through December 2020. Patients who underwent orthotopic heart transplantation (OTx) were followed until their transplant. Patients who were found in the original study… More >

Abstract

Herein, we reported a method to prepare magnetic sodalite sphere by using the mud from backwash wastewater after polyaluminum chloride (PAC) coagulation. The results showed that approximately 100% of Fe in the wastewater was precipitated as flocculent iron mud (FM) by adding PAC. FM was converted to spherical magnetic sodalite (FMP) with a diameter of 3 μm via a facile alkali hydrothermal method without adding Al/Si resources or reductant. The product FMP had the saturated magnetization of 10.9 emu g⁻¹ and high Zn²⁺ adsorption capacity of 50.6 mg g⁻¹. Without coagulation with PAC, the removal rate of

Abstract Wunderlich syndrome (WS) is a rare triad of flank pain, flank mass and hypovolemic shock and is classically attributed to angiomyolipomata or neoplasms. Treatment is guided by clinical severity: conservative, selective arterial embolization, or nephrectomy. We report an atypical case of a 69-year old man with a pre-existing 9 cm left renal tumor who developed WS secondary to anticoagulation and simple cyst rupture from his contralateral kidney, complicated by abdominal compartment syndrome with hemodynamic instability despite inotropic support and robust resuscitation. Early recognition and source control via radical nephrectomy were essential in securing a positive More >

Abstract Appropriate perioperative management of antithrombotic medications is critical; for every patient, the risk of bleeding must be balanced against individual risk of thrombosis. There has been a rapid influx of new antithrombotic therapies in the past 5 years, yet there is a lack of clear and concise guidelines on the management of anticoagulant and antiplatelet therapy during urologic surgery. Here we describe our approach to perioperative antithrombotic counseling, including the timing of stopping and restarting these medications. These practice guidelines have been developed in consultation with the Vascular Medicine service at our institution as well More >

Abstract Endotoxin is a a very powerful and toxic inflammatory stimulator usually leading to the sepsis occurred. In order to remove endotoxin better through hemoperfusion, it is a pretty choice to increase the length of molecular linker on adsorbents. In this study, we chose the heparin as a molecular linker because of its being anticoagulant linear polysaccharide. Heparin as a linker was covalently immobilized on the chloromethylated polystyrene microspheres (Ps) and then connected with L-phenylalanine (Phe) forming the Ps-Hep-Phe structure to adsorbed endotoxin better. The property of microspheres was characterized by Fourier transform infrared spectroscopy, X-ray More >

Abstract Background: In adults with congenital heart disease (CHD) and atrial arrhythmias, recommendations for thromboprophylaxis are vague and evidence is lacking. We aimed to identify factors that influence decision-making in daily practice.
Methods: From the Swiss Adult Congenital HEart disease Registry (SACHER) we identified 241 patients with either atrial fibrillation (Afib) or atrial flutter/intraatrial reentrant tachycardia (Aflut/ IART). The mode of anticoagulation was reviewed. Logistic regression models were used to assess factors that were associated with oral anticoagulation therapy.
Results: Compared with patients with Aflut/IART, patients with Afib were older (51 ± 16.1 vs 37 ± 16 years, P… More >

Abstract Objective: This quality improvement study was implemented to demonstrate consistent and reliable post procedure anticoagulation for patients undergoing left-sided ablations. We evaluated the safety and efficacy of anticoagulation practice during a transition from anticoagulation with overnight infusion of unfractionated heparin to a single subcutaneous injection of low molecular weight heparin.
Methods: Outcomes for patients who received unfractionated heparin from January 2014 to October 2014, were compared with outcomes of patients who received low molecular weight heparin from October 2014 to October 2015. Complications prepractice and postpractice change were documented and compared to establish confidence in the practice… More >
