Genetics of hyperhomocysteinemia and 1-carbon metabolism: implications for retinal structure and eye functions.
Abstract Homocysteine (Hcy); a sulfur-containing non-proteinogenic amino acid is generated as a metabolic intermediate. Hcy constitutes an important part of the "1-carbon metabolism" during methionine turnover. Elevated levels of Hcy known as hyperhomocysteinemia (HHcy) results from vitamin B deficiency, lack of exercise, smoking, excessive alcohol intake, high fat and methionine rich diet, and the underlying genetic defects. These factors directly affect the "1-carbon metabolism (methionine-Hcy-folate)" of a given cell. In fact, the Hcy levels are determined primarily by dietary intake, vitamin status, and the ge...

Determinants of Antithrombotic Treatment for Atrial Fibrillation in Octogenarians: Results of the OCTOFA Study
ConclusionsMost private-practice cardiologists prescribe anticoagulant treatment according to current guidelines in elderly atrial fibrillation patients. Non-vitamin K antagonist oral anticoagulants represent a significant proportion of prescriptions.

Real-life Performance of Edoxaban in Elderly Patients With Atrial Fibrillation: a Multicenter Propensity Score-Matched Cohort Study.
Abstract PURPOSE: The purpose of the current study was to compare the efficacy and safety of edoxaban versus vitamin K antagonist (VKA) therapy among a cohort of elderly patients (ie, those aged ≥75 years) with atrial fibrillation (AF) in a real-life setting. METHODS: A propensity score-matched cohort observational study was performed comparing the safety and efficacy of edoxaban versus VKA therapy among a cohort of elderly (aged ≥75 years) patients with AF in a real-life setting. Follow-up data were obtained through outpatient visits at 1, 3, and every 6 months. The primary safety outcome was major bleed...

Preventable Cases of Oral Anticoagulant-Induced Bleeding: Data From the Spontaneous Reporting System
Conclusion: Our findings describe the most reported risk factors for preventability of oral anticoagulant-induced bleedings. These factors may be useful for targeting interventions to improve pharmacovigilance activities in our regional territory and to reduce the burden of medication errors and inappropriate prescription. Introduction Oral anticoagulant therapy is widely used for the prevention of stroke and systemic embolism in patients with atrial fibrillation, or for the prevention and treatment of deep vein thrombosis and pulmonary embolism (Raj et al., 1994; Monaco et al., 2017). Oral anticoagulants can be di...

Plant-Derived Alkaloids: The Promising Disease-Modifying Agents for Inflammatory Bowel Disease
Conclusion This paper summarizes the current findings regarding the anti-colitis activity of plant-derived alkaloids and shows how these alkaloids exhibit significant and beneficial effects in alleviating colonic inflammation. These natural alkaloids are not only promising agents for IBD treatment but are also components for developing new wonder drugs. However, the underlying molecular mechanisms or toxicological evaluation of most plant-derived alkaloids still require much scientific research, and their actual efficacies for IBD patients have not been verified well in field research. Thus, further clinical trials to elu...

Nrf2 as a Potential Mediator of Cardiovascular Risk in Metabolic Diseases
Conclusion Activation of the Nrf2-dependent antioxidant system plays an important role in cell defense against oxidative stress damage, whereas the insufficiency of the Nrf2 system is associated with multiple aspects of the genesis and progression of metabolic diseases, posing a great risk to the cardiovascular system (Figure 1). The systemic increase of Nrf2 activity by several activators may be beneficial in the treatment of metabolic diseases. In addition, selective upregulation of Nrf2 genes may represent a potential therapy in obesity, diabetes and atherosclerosis. Looking to the future, experimental research that el...

Assessment of Condition and Medication Knowledge Gaps Among Atrial Fibrillation Patients: A Systematic Review and Meta-analysis.
Conclusion and Relevance: This systematic review identified several AF patient knowledge gaps about their condition and its treatment that can inform the development of AF patient education programs. PMID: 30829052 [PubMed - as supplied by publisher]

Benefits and Risks of Anticoagulation in Acute Coronary Syndrome
Conclusions: Many risk factors for ischemic events and bleeding overlap. The clinician's challenges include monitoring patients' adherence and global assessment of the antithrombotic effect that incorporates antiplatelet and anticoagulant effects.

Oral Anticoagulants With Dual Antiplatelet Therapy Versus Clopidogrel in Patients After Percutaneous Coronary Intervention: A Meta-Analysis
Conclusions: In patients who are on OAC with vitamin K antagonist and underwent percutaneous coronary intervention, no significant differences were found in mortality, ischemic, and hemorrhagic complications between the patients treated with TT and DT. Thus, tailored treatment based on individual thromboembolic and bleeding risk might be the most reasonable approach in these patients.

Neurologic conditions and disorders of uremic syndrome of chronic kidney disease: Presentations, causes and treatment strategies.
Authors: Hamed SA Abstract INTRODUCTION: Uremic syndrome of chronic kidney disease (CKD) is a term used to describe clinical, metabolic and hormonal abnormalities associated with progressive kidney failure. It is a rapidly growing public health problem worldwide. Nervous system complications occur in every patient with uremic syndrome of CKD. Areas covered: This review summarized central and peripheral nervous system complications of uremic syndrome of CKD and their pathogenic mechanisms. They include cognitive deterioration, encephalopathy, seizures, asterixis, myoclonus, restless leg syndrome, central pontine mye...

Antithrombotic medications and their impact on fibrin clot structure and function.
Authors: Undas A, Zabczyk M Abstract Fibrin constitutes a major protein component of intravascular thrombi in all locations. Fibrin formation and its functions are essential for physiological hemostasis and the pathologic thrombosis. Formation of dense fibrin networks which are relatively resistant to lysis is observed in patients with venous or arterial thromboembolism, including myocardial infarction, ischemic stroke and venous thromboembolism. Measures of clot characteristics, in particular clot permeability and clot lysis time, may predict arterial and venous recurrent thromboembolic events. Medications, includ...

Anti-Xa Oral Anticoagulant Plasma Concentration Assay in Real Life: Rivaroxaban and Apixaban Quantification in Emergency With LMWH Calibrator.
Conclusion and Relevance: In the absence of a specific test, LMWH-calibrated anti-Xa assay could be used to determine the presence and evaluate the plasma concentration of oral anti-Xa inhibitors. However, these initial findings require confirmation using other chromogenic calibrated oral anti-Xa assays. PMID: 30378443 [PubMed - as supplied by publisher]
