BACKGROUND: The ideal oral anticoagulant agent during catheter ablation (CA) for atrial fibrillation (AF) remained unclear. HYPOTHESIS: Novel oral anticoagulants (NOACs) are safer and effective compared to uninterrupted vitamin K antagonists (U-VKA) among patients requiring CA for AF. METHODS: Four randomized controlled trials (RCTs) and 9 observational studies (OS) were selected using PubMed/Medline, EMBASE and the CENTRAL data bases (Inception-December-2017)...

Atrial fibrillation (AF) occurs approximately in 3% of general population, with greater prevalence in elderly. Non-vitamin K-dependent oral anticoagulant agents (NOACs) according to the current European guidelines are recommended for patients with AF at high risk for stroke as a first-choice treatment. NOACs are not inferior to warfarin or some of them are better than warfarin in reducing the rate of ischemic stroke. Moreover, they significantly reduce the rate of intracranial hemorrhages, major bleedings, and mortality compared with warfarin...

Continuous flow left ventricular assist devices (CF-LVAD) require therapeutic anticoagulation which is often interrupted for procedures or bleeding. Prior to the availability of four factor prothrombin complex concentrate (4F-PCC) in the United States, warfarin was held and its effects reversed by vitamin K or fresh frozen plasma. We evaluated the use of 4F-PCC for temporary warfarin reversal in patients with CF-LVADs and assessed outcomes. This analysis is a retrospective study of CF-LVAD patients who received 4F-PCC for warfarin reversal in the setting of bleeding or need for urgent or elective procedures...

Disulfide bonds influence stability and activity of many proteins. In Escherichia coli the DsbA and DsbB enzymes promote disulfide bond formation. Other bacteria, including the Actinobacteria, use instead of DsbB the enzyme VKOR (Vitamin K Epoxide Reductase), which is found either fused to or encoded in the same operon as a dsbA -like protein. Mycobacterium tuberculosis and other gram-positive Actinobacteria secrete to the cell envelope many proteins with even numbers of cysteines. These organisms have predicted oxidoreductases and VKOR orthologs...

BACKGROUND: Wear resistance of ultrahigh molecular weight polyethylene (UHMWPE) is improved via ionizing radiation crosslinking and subsequent high temperature melting for improved toughness. Our group has previously reported that crosslinking can also be achieved chemically using organic peroxides. However, volatile peroxide byproducts are generated during consolidation. The purpose of this study was to quantify elution of volatile peroxide byproducts from UHMWPE before and after in vivo implantation, and to determine their effects on local tissues...

AIMS: Inverse associations between vitamin D status and risk of type 2 diabetes observed in epidemiological studies could be biased by confounding and reverse causality. We investigated the prospective association between vitamin D status and type 2 diabetes and the possible role of reverse causality. METHODS: We conducted a case-cohort study within the Melbourne Collaborative Cohort Study (MCCS), including a random sample of 628 participants who developed diabetes and a sex-stratified random sample of the cohort (n=1,884)...

Vitamin D (vit-D) deficiency is highly prevalent in patients with gastro-entero-pancreatic neuroendocrine tumors (GEP-NET) and has been linked to reduced overall survival. We here assessed the vit-D status in 183 patients with GEP-NET at the time of their first presentation in the ARDEN NET Centre. We further examined the effect of simple advice to increase vit-D intake using over-the-counter vit-D preparations [colecalciferol (Vit-D3), 1,000-2,000 units/day], over a prospective observation period of 24 mo...

Dual antiplatelet therapy (DAPT) has been the cornerstone of antithrombotic management for patients undergoing percutaneous coronary intervention (PCI). Despite low-quality evidence, triple antithrombotic therapy involving acetylsalicylic acid, clopidogrel and warfarin or non-vitamin K antagonist oral anticoagulant (NOAC) has been recommended in patients with concomitant atrial fibrillation undergoing PCI, who require long-term oral anticoagulation, although such strategy is associated with a substantially increased risk of bleeding compared with DAPT...

Venous thromboembolism (VTE) is a serious complication during and after hospitalization, yet is a preventable cause of in-hospital death.Without VTE prophylaxis, the overall VTE incidence in medical and general surgery hospitalized patients is in the range of 10% to 40%, while it ranges up to 40% to 60% in major orthopaedic surgery. With routine VTE prophylaxis, fatal pulmonary embolism is uncommon in orthopaedic patients and the rates of symptomatic VTE within three months are in the range of 1.3% to 10%.VTE prophylaxis methods are divided into mechanical and pharmacological...

BACKGROUND Acquired hemophilia A (AH) is a rare hemorrhagic diathesis, characterized by the presence of autoantibodies directed against the pro-coagulant activity of factor VIII. It is associated with rheumatoid arthritis (RA) in 4% to 8% of cases and its prognosis remains severe. CASE REPORT A 66-year-old patient has been followed up for 20 years for deforming and severe RA, which was in low-disease activity. However, the patient presented a polyarticular flare involving the metacarpophalangeal and the proximal interphalangeal joints, the left elbow, and the right knee, which was warm and swollen...

BACKGROUND: Cerebral microbleeds are a potential neuroimaging biomarker of cerebral small vessel diseases that are prone to intracranial bleeding. We aimed to determine whether presence of cerebral microbleeds can identify patients at high risk of symptomatic intracranial haemorrhage when anticoagulated for atrial fibrillation after recent ischaemic stroke or transient ischaemic attack. METHODS: Our observational, multicentre, prospective inception cohort study recruited adults aged 18 years or older from 79 hospitals in the UK and one in the Netherlands with atrial fibrillation and recent acute ischaemic stroke or transient ischaemic attack, treated with a vitamin K antagonist or direct oral anticoagulant, and followed up for 24 months using general practitioner and patient postal questionnaires, telephone interviews, hospital visits, and National Health Service digital data on hospital admissions or death...

BACKGROUND: 2-Keto-L-gulonic acid (2-KGA), the precursor of vitamin C, is currently produced by two-step fermentation. In the second step, L-sorbose is transformed into 2-KGA by the symbiosis system composed of Ketogulonicigenium vulgare and Bacillus megaterium. Due to the different nutrient requirements and the uncertain ratio of the two strains, the symbiosis system significantly limits strain improvement and fermentation optimization. RESULTS: In this study, Ketogulonicigenium robustum SPU_B003 was reported for its capability to grow well independently and to produce more 2-KGA than that of K...

INTRODUCTION: Warfarin therapy is recommended in children with giant coronary artery aneurysms (GCAAs) after Kawasaki disease (KD). Large individual variability makes it difficult to predict the warfarin dose. Polymorphisms in the vitamin K expoxide reductase 1 (VKORC1) and cytochrome P4502C9 (CYP2C9) genes have been reported to influence the warfarin dose. We investigated the effects of the VKORC1 and CYP2C9 genotypes on the warfarin dose in pediatric patients with giant CAAs after KD...

BACKGROUND: The anticoagulation of atrial fibrillation catheter ablation during the perioperative stage does matter and should be treated with discretion. We aimed to assess impact of three important genes participating in vitamin K cycle (i.e. VKORC1 rs9923231, CYP4F2 rs2108622 and NQO1 rs1800566) on the daily stable warfarin dose requirement in Sichuan Han Chinese patients with catheter ablation of atrial fibrillation. METHODS: A total of 222 atrial fibrillation patients taking stable warfarin therapy after catheter ablation operation were enrolled in this study...

BACKGROUND: Diet quality among federal food assistance program participants remains low, and little research has assessed the diet quality of food insecure non-participants. Further research is needed to assess the extent to which food substitutions can improve the nutritional status of these vulnerable populations. Substituting egg dishes for other commonly consumed dishes at certain eating occasions may be an effective strategy for improving the daily nutrient intake among these groups...
