Migraine and patent foramen ovale: correlation, coexistence, dependence. A narrative review

open access: yesHeadache: The Journal of Head and Face Pain, EarlyView.
Plain Language Summary This review looked at what scientists know about the connection between migraine and a small heart opening called a patent foramen ovale (PFO). It showed that people with migraine, especially with aura, often have PFO, but it is not certain whether closing this heart opening helps prevent strokes in these patients.

Pediatric acute paradoxical cerebral embolism with pulmonary embolism caused by extremely small patent foramen ovale

open access: yesOpen Medicine, 2018
Herein, we report a pediatric case of acute paradoxical cerebral embolism complicated by serious acute pulmonary embolism that was caused by an extremely small patent foramen ovale (PFO). The patient had no medical history suggestive of any other reason.

Ischaemic strokes in patients with pulmonary arteriovenous malformations and hereditary hemorrhagic telangiectasia: associations with iron deficiency and platelets. [PDF]

open access: yes, 2014
BackgroundPulmonary first pass filtration of particles marginally exceeding ∼7 µm (the size of a red blood cell) is used routinely in diagnostics, and allows cellular aggregates forming or entering the circulation in the preceding cardiac cycle to lodge ...

Classification of Platelet‐Activating Anti‐Platelet Factor 4 Disorders

open access: yesInternational Journal of Laboratory Hematology, EarlyView.
ABSTRACT Introduction The prototypic anti‐platelet factor 4 (PF4) disorder—heparin‐induced thrombocytopenia and thrombosis (HITT)—features immunoglobulin G (IgG) class antibodies that activate platelets, monocytes, and neutrophils in a mainly heparin‐dependent fashion via Fcγ receptor‐dependent cellular activation.

Pulmonary Thromboembolism in a Patent With Patent Foramen Ovale

open access: yesCase Reports in Clinical Practice, 2019
During the recent years, paradoxical embolism and Patent Foramen Ovale (PFO) have drawn great attention because of their strong correlation with cryptogenic stroke in young patients.

Stroke and Bleeding Risks in Atrial Fibrillation Are Not Static but Dynamic: A Dynamic Assessment of CHA2DS2‐VASc and HAS‐BLED Scores in the Iranian Registry of Atrial Fibrillation (IRAF)

open access: yesJournal of Cardiovascular Electrophysiology, EarlyView.
ABSTRACT Background and Objectives Proper stroke and bleeding risk assessment is an essential part of clinical decision‐making in patients with atrial fibrillation (AF). This study aims to determine whether the dynamic assessment of CHA2DS2‐VASc and HAS‐BLED scores over time enhances stroke and bleeding risk prediction.

The regional evolution of a dryland fluvio‐aeolian and lacustrine succession in response to allocyclic forcing: insights from the Early Permian Cutler Group, Utah, USA

open access: yesSedimentology, EarlyView.
ABSTRACT Preserved allocyclic signatures in the rock record often reflect basin‐scale climatic variability and serve as key proxies for correlating ancient dryland successions. The notion of climate cyclicity, however, remains largely untested on regionally constrained, outcrop‐calibrated studies.

Acute ECG ST-segment elevation mimicking myocardial infarction in a patient with pulmonary embolism

open access: yesCardiovascular Ultrasound, 2010
Pulmonary embolism is a common cardiovascular emergency, but it is still often misdiagnosed due to its unspecific clinical symptoms. Elevated troponin concentrations are associated with greater morbidity and mortality in patients with pulmonary embolism.

Modelling the effect of varying metabolic rate and cardiac output on estimated tissue and blood O2 and CO2 levels in an extreme deep‐diver, the goose‐beaked whale (Ziphius cavirostris)

open access: yesExperimental Physiology, EarlyView.
Abstract High‐resolution movement data from Cuvier's beaked, or goose‐beaked whale (Ziphius cavirostris, hereafter Ziphius, n = 8) tag deployments (4.1–19.2 days) were used to estimate blood and tissue O2 and CO2 levels. Acceleration and magnetometry data were used to estimate the locomotion cost (LC) from the relationship between activity and the O2 ...

Cellular and molecular cross‐talk in atrial fibrillation: The role of non‐cardiomyocytes in creating an arrhythmogenic substrate

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Illustration of cellular and molecular cross‐talk in atrial fibrillation. Left: a schematic of cardiac tissue showing cardiomyocytes, fibroblasts, adipocytes, inflammatory cells and the coagulation system. Right: direct and indirect cross‐talk between different cell types, with the impact of direct cross‐talk on action potential (
