Vitamin K antagonists for stroke prevention in hemodialysis patients with atrial fibrillation: a systematic review and meta-analysis
Conclusion Our meta-analysis revealed a trend for a reduction of the risk of ischemic stroke in hemodialysis patients with AF treated with VKA. The true protective effect may have been underestimated, owing to inclusion of low-risk patients not expected to benefit from anticoagulation and to suboptimal anticoagulation. However, assessment of the overall effect of VKA in hemodialysis patients should also take into account the increased risk of bleeding, in particular of hemorrhagic stroke. Whether new oral anticoagulants provide a better benefit–risk ratio in hemodialysis patients should be the subject of future trials.

Effectiveness and Safety of Dabigatran, Rivaroxaban, and Apixaban Versus Warfarin in Nonvalvular Atrial Fibrillation Health Services and Outcomes Research
Conclusions In patients with nonvalvular atrial fibrillation, apixaban was associated with lower risks of both stroke and major bleeding, dabigatran was associated with similar risk of stroke but lower risk of major bleeding, and rivaroxaban was associated with similar risks of both stroke and major bleeding in comparison to warfarin.

Neurosurgical intervention in children with ventricular assist devices: A single center case series review
CONCLUSIONS: Perioperative concerns for the anesthesiologist include VAD hemodynamic management, bleeding, VAD thrombosis, and prevention of secondary brain injury. A systematic, multidisciplinary approach to management is paramount to attain favorable outcomes.PMID:34478592 | DOI:10.1111/pan.14287

019 * is antiplatelet therapy required in heartmate ii patients? preliminary results from the european trace study
Conclusion: This preliminary analysis of the observational TRACE-EU study suggests that managing HMII patients with a vitamin K antagonist without aspirin may help to reduce the incidence of major bleeding without increasing the risk of thrombo-embolic events including ischaemic stroke and device thrombosis. Further prospective studies are needed.

Interventions for preventing bone disease in kidney transplant recipients.
CONCLUSIONS: Bisphosphonate therapy may reduce fracture and bone pain after kidney transplantation, however low certainty in the evidence indicates it is possible that treatment may make little or no difference. It is uncertain whether bisphosphonate therapy or other bone treatments prevent other skeletal complications after kidney transplantation, including spinal deformity or avascular bone necrosis. The effects of bone treatment for children and adolescents after kidney transplantation are very uncertain. PMID: 31637698 [PubMed - as supplied by publisher]

Sailing between Scylla and Charybdis: oral long-term anticoagulation in dialysis patients
End-stage renal disease (ESRD) patients exhibit an increased risk of bleeding compared with non-chronic kidney disease (CKD) patients due to uraemic platelet dysfunction, altered vessel architecture and other factors. This renders any long-term oral anticoagulation potentially difficult. While there is little doubt that ESRD patients with recurrent thromboembolism or a mechanical cardiac valve should receive vitamin K antagonists (coumarins), the use of coumarins in ESRD patients with atrial fibrillation is a matter of debate. In non-CKD patients, current guidelines strongly recommend the use of oral anticoagulants for str...

Liver or Combined Liver-Kidney Transplantation for Patients with Isolated Methylmalonic Acidemia: Who and When?
The hereditary disorders of vitamin B12 (cobalamin) and methylmalonic acid metabolism comprise a major group of organic acid disorders that are collectively common inborn errors of metabolism.1 Affected patients are medically fragile and suffer multisystemic complications, such as lethal metabolic instability, metabolic stroke, pancreatitis, end-stage renal failure, growth impairment, osteopenia, optic nerve atrophy, and neurocognitive delay.2 The frequency of these complications and their precipitants, long-term sequelae, and optimal treatment regimens remain ill-defined.

Bone Morphogenetic Proteins: Inhibitors of Myelination in Development and Disease.
Abstract Myelin, the lipid membrane that surrounds axons, is critical for the propagation of nervous impulses and axonal maintenance. The destruction of myelin or lack of myelin formation due to disease or injury causes severe motor and cognitive disability. Regeneration of myelin is theoretically possible but rarely happens. Myelin is synthesized as the plasma membrane of the oligodendrocyte in the central nervous system. During development, myelin and oligodendrocytes are generated from oligodendrocyte progenitors through a process modulated by extrinsic growth factors signaling to cell-intrinsic proteins. Among...

In this substudy of eligible China Stroke Primary Prevention Trial (CSPPT), 15 104 participants with an estimated glomerular filtration rate (eGFR) 30 mL/min/1.73 m2 or greater, were randomized to receive a single tablet daily containing 10 mg enalapril and 0.8 mg folic acid (n = 7545) or 10 mg enalapril alone (n = 7559). Overall, 15 104 Chinese adults with a mean (range) age of 60 (45-75) years were recruited; median follow-up was 4.4 years. There were 164 and 132 primary events in the enalapril group and the enalapril-folic acid group, respectively. Compared with the enalapril group, the enalap...

How to Boost Your Stem Cells
A California man named Kris Boesen was completely paralyzed after breaking his neck in a terrible car crash last March. But now he can brush his teeth and hug his family again… He's even started to regain sensation in his legs. And it's all because of a simple procedure he underwent about a month after his accident: stem cell therapy. During Kris' procedure, researchers at the University of Southern California injected 10 million stem cells into his spinal cord. Within two weeks, he could wiggle his fingers. Three months later, he was able to feed himself, write his name and operate his wheelchair. His re...

A Review of the Use of Direct Oral Anticoagulant Use in Orthotopic Heart Transplantation Recipients
Over 60 years ago, the vitamin K antagonist (VKA) warfarin was approved and remained the only oral anticoagulation agent until recently [1]. Currently, within North America and Europe there are four DOACs available. Dabigatran, first approved in Europe and Canada in 2008, then in the United States of America in 2010, followed by rivaroxaban, apixaban, and most recently edoxaban. The introduction of direct oral anticoagulants (DOACs) has been a major advancement and these agents are the preferred to VKAs for many indications [2 –5], including stroke prevention in nonvalvular atrial fibrillation (NVAF), acute treatment and...
