Adult and pediatric mechanical circulation: a guide for the hematologist.
Authors: Kreuziger LB, Massicotte MP Abstract Mechanical circulatory support (MCS) is the overarching term that encompasses the temporary and durable devices used in patients with severe heart failure. MCS disturbs the hematologic and coagulation system, leading to platelet activation, activation of the contact pathway of coagulation, and acquired von Willebrand syndrome. Ischemic stroke and major hemorrhage occur in up to 30% of patients. Hematologists are an essential part of the MCS team because they understand the delicate balance between bleeding and clotting and alteration of hemostasis with antithrombotic th...

Screening mammography beyond breast cancer: breast arterial calcifications as a sex-specific biomarker of cardiovascular risk
ConclusionsThere is a strong rationale for mammography to become a dual test for breast cancer screening and CV disease prevention. However, robust and automated quantification methods are needed for a deeper insight on the association between BAC and CV disease, to stratifying CV risk and define personalized preventive actions.Graphical abstract

Using Artificial Intelligence to Manage Thrombosis Research, Diagnosis, and Clinical Management
Semin Thromb Hemost DOI: 10.1055/s-0039-1697949Thrombosis development in either arterial or venous system remains a major cause of death and disability worldwide. This poorly controlled in vivo clotting could result in many severe complications including myocardial infarction, venous thromboembolism, stroke, and cerebral venous thrombosis, to name a few. These conditions are collectively known as thromboembolic disorders (TEDs). Appropriate understanding of TEDs is challenging, as they are multifactorial and involve several and often different risk factors. Hence, it requires a collective effort and data from numerous rese...

Clot Analog Attenuation in Non-contrast CT Predicts Histology: an Experimental Study Using Machine Learning
AbstractExact histological clot composition remains unknown. The purpose of this study was to identify the best imaging variables to be extrapolated on clot composition and clarify variability in the imaging of thrombi by non-contrast CT. Using a CT-phantom and covering a wide range of histologies, we analyzed 80 clot analogs with respect to X-ray attenuation at 24 and 48  h after production. The mean, maximum, and minimum HU values for the axial and coronal reconstructions were recorded. Each thrombus underwent a corresponding histological analysis, together with a laboratory analysis of water and iron contents. Decision...

Biventricular imaging markers to predict outcomes in non ‐compaction cardiomyopathy: a machine learning study
ConclusionsOur findings show the importance of biventricular assessment to detect the severity of this cardiomyopathy and to plan for early clinical intervention. In addition, this study shows that even patients with normal LV function and negative late gadolinium enhancement had MACE. ML is a promising tool for analysing a large set of parameters to stratify and predict prognosis in LVNC patients.

Cerebral venous thrombosis in patients with COVID-19 infection: a case series and systematic review
: There has been increasing reports associating the coronavirus disease 2019 (COVID-19) with thromboembolic phenomenon including ischemic strokes and venous thromboembolism. Cerebral venous thrombosis (CVT) is a rare neurovascular emergency that has been observed in some COVID-19 patients, yet much remains to be learnt of its underlying pathophysiology.

Ce-543-04 inter-atrial block identifies patients with low cha2ds2-vasc score but high stroke risk
Beyond current methods of risk stratification, clinical studies employing machine learning methodology have demonstrated that the 12-lead ECG harbors additional prognostic information for various cardiovascular outcomes. Interatrial block (IAB) manifests as P wave duration>120 msec and is associated with thromboembolism, atrial arrhythmias, and mortality.

What Causes Sudden Vision Loss?
Discussion Vision loss, whether chronic or acute, is distressing at any time for patients and families. Prompt evaluation and treatment are important as maintenance of any acuity and light or movement is considered paramount. Most vision loss is due to chronic problems and aging issues but the differential diagnosis is broad. For any age, but especially children, uncorrected refractive errors can cause problems in not only in childhood but throughout someone’s lifetime. Visual impairment for distance vision is considered mild if worse than 6/12 in meters = 20/40 in feet or 0.3 LogMAR and for moderate impairment is 6/...

Is This Primary Exertional Headache?
Discussion Commonly occurring primary headaches include tension, cluster and migraine headaches. “Other primary headaches” are often situational. Patients can have more than 1 type of these “other” headaches along with more common headaches. Other primary headaches as a group tend to be self-limited with long remission periods. Some other primary headaches include: Thunderclap headache Explosive sudden onset with maximum intensity in less 1 minute and resolution within 5 minutes usually 43/100,000 persons in adults Primary or secondary Secondary causes include intracranial hemorrhage, stroke, thro...

Not to be sneezed at: cardiovascular disease after COVID-19 infection
COVID-19 has changed our way of life since it was first identified in December of 2019. While our understanding of the manifestations and outcomes of the immediate acute illness has improved, we are still learning about the medium to long-term impact of this diagnosis on patients’ health. For some time, it has been suggested that COVID-19 may be associated with incident cardiovascular events such as venous thromboembolism, stroke and myocardial infarction.1 However, the absolute risk of these events and whether an excess risk is present are challenging to determine without a contemporary reference population. This is...
