Thrombus in transit through a patent foramen ovale: An unusual cause of cardiac embolism
Publication date: Available online 13 December 2019Source: Journal of the Saudi Heart AssociationAuthor(s): Carlos Minguito-Carazo, Tomás Benito-González, Julio Cesar Echarte-Morales, Mario Castaño-Ruiz, Felipe Fernández-VázquezAbstractA 78-year-old woman with a history of transient ischemic attack was admitted for sudden aphasia. In order to assess the potential cardioembolic source an echocardiogram was performed, which revealed a large mass consistent with a thrombus in transit through a patent foramen ovale. Because of the high risk of systemic embolism, emergent surgical thrombectomy was performed with the intention to discharge the patient safely without any new embolic events. This case report highlights the importance of echocardiography in the evaluation of cardioembolic stroke and the requirement of an emergent approach in case of impending paradoxical embolism.
Authors: Nyamu DG, Guantai AN, Osanjo GO, Godman B, Aklillu E Abstract Background: Patients' profiles affect the outcome with warfarin; however, this data, and its implications, is scarce in resource-poor countries such as Kenya without access to pharmacogenetics or regular INR testing.Objectives: To characterize the profiles of patients on long-term warfarin therapy and subsequently use the findings to guide future anticoagulation management.Methods: Cross-sectional study undertaken among 180 adult patients receiving warfarin therapy in anticoagulation clinics at a leading referral hospital in Kenya. Sociodemograp...
Authors: Osei-Owusu J, Yang J, Del Carmen Vitery M, Tian M, Qiu Z Abstract Severe local acidosis causes tissue damage and pain, and is associated with many diseases, including cerebral and cardiac ischemia, cancer, infection, and inflammation. However, the molecular mechanisms of the cellular response to extracellular acidic environment are not fully understood. We recently identified a novel and evolutionarily conserved membrane protein, PAC (also known as PACC1 or TMEM206), encoding the proton-activated chloride (Cl-) channel, whose activity is widely observed in human cell lines. We demonstrated that genetic del...
Conclusions: Our study further expands the spectrum of the sequence variants reported in the DGKE gene and also indicates that different races may have different DGKE variants. Moreover, the altered structures and conformations, caused by DGKE mutations, disrupt the binding of DGKE with its partners, and leading to the occurrence of aHUS.

CONCLUSIONS: Melatonin protected SH SY5Y cells from OGD/R induced oxidative stress, inflammation, apoptosis, and autophagy by blocking NF-κB signaling and activating Nrf2/HO-1, Akt, and mTOR/p70S6K/4E-BP-1 pathways, thereby indicating that melatonin is a potential and novel therapeutic drug for ischemic stroke.

CONCLUSIONS: In patients with anterior cerebral artery-occluded AIS, the TC level is a promising prognosis marker for the IV thrombolysis outcome. PMID: 32096200 [PubMed - in process]
Conclusions regarding improvement in functional improvement cannot be drawn. Further trials are needed to strengthen the evidence on this topic. PMID: 32096199 [PubMed - in process]
CONCLUSIONS: MiR-155-5p accelerates cerebral I/R injury via targeting DUSP14 by regulating NF-κB and MAPKs signaling pathways. Inhibition of miR-155-5p significantly reduces apoptosis and brain injury. These results indicated that miR-155-5p plays a key role in cerebral I/R injury and has the potential to be explored as a new target for ischemic stroke. PMID: 32096190 [PubMed - in process]
CONCLUSIONS: The prevalence of AF in CS should be studied more precisely, both in a scientific way and at the individual patient's level. PMID: 32096188 [PubMed - in process]
A 57-year-old man with atherosclerosis obliterans was admitted with sudden-onset sensory aphasia and right hemiparesis. Brain MRI revealed acute cerebral infarctions in the left temporal lobe and magnetic resonance angiography showed occlusion of the posterior branch of the left middle cerebral artery. Transesophageal echocardiography and ultrasonography respectively confirmed a patent foramen ovale and deep vein thrombosis in the bilateral femoral veins. Blood findings showed low protein S antigen, low protein S activity, and a missense mutation of the PROS 1 gene.
