Headache in Pregnancy, the Puerperium, and menopause.

Semin Neurol 2018 Dec 6;38(6):627-633. Epub 2018 Dec 6.

Department of Neurology, University at Buffalo School of Medicine and Biomedical Sciences, The State University of New York, Buffalo, New York.

Headache is a neurologic disorder that displays gender dichotomy. It is well established that there is a strong link between migraine headache and sex hormones, specifically estrogen, which influences the severity of migraines during the menstrual cycle, pregnancy, and menopause. Furthermore, the epidemiology of headaches during pregnancy and the postpartum period is very distinct from that in males or nonpregnant females, in part due to the hemodynamic and hematologic changes that occur during pregnancy.

Tracking Arteriovenous Fistula Maturation: A Novel Approach.

Blood Purif 2018 Dec 6:1-6. Epub 2018 Dec 6.

Renal Research Institute, New York, New York, USA.

Background: The time between the creation of an arteriovenous fistula (AVF) and its successful use is significantly longer in hemodialysis (HD) patients in the United States compared to those in other countries, and there is an urgent need to reduce the residence time of central-venous catheters (CVC).

Methods: Successful AVF creation and maturation results in typical hemodynamic changes, such as an increase in cardiac output and upper body blood flow (UBBF). In patients with CVC as vascular access, we measured once per minute intradialytic central-venous oxygen saturation (ScvO2) and hemoglobin levels simultaneously using the Crit-Line Monitor.

Association of Central Venous Oxygen Saturation Variability and Mortality in Hemodialysis Patients.

Blood Purif 2018 Dec 6:1-8. Epub 2018 Dec 6.

Renal Research Institute, New York, New York,

Background: Central venous oxygen saturation (ScvO2) is correlated with cardiac output. In most patients, ScvO2 declines during hemodialysis (HD) due to factors such as reduced preload, myocardial stunning, and intermittent arrhythmias. Previous research has shown that low ScvO2 is associated with higher mortality in chronic HD patients. Read More

Insight into the perioperative management of direct oral anticoagulants: concerns and considerations.

Expert Opin Pharmacother 2018 Dec 6:1-8. Epub 2018 Dec 6.

d Division of Cardiology, Department of Medicine and Therapeutics , The Chinese University of Hong Kong, Prince of Wales Hospital , Hong Kong , China.

Introduction: Direct oral anticoagulants (DOACs) have gained momentum in recent years in patients requiring anticoagulation for the prevention and management of venous thromboembolism and thromboembolic events caused by atrial fibrillation. The use of these agents involves potential bleeding complications, particularly during invasive procedures. With increasing use of DOACs, adequate knowledge regarding the perioperative management of patients on DOACs has become indispensable. Read More

Novel Insights in the Activation Patterns at the Pulmonary Vein Area.

Circ Arrhythm Electrophysiol 2018 Nov;11(11):e006720

Department of Cardiology, Erasmus Medical Center, Rotterdam, The Netherlands (E.M.J.P.M., L.J.M.E.v.d.D., E.A.H.L., C.P.T., P.K., N.M.S.d.G.).

Background: Extensiveness of conduction delay and block at the pulmonary vein area (PVA) was quantified in a previous study. We hypothesized that the combination of lines of conduction block with multiple concomitantly entering sinus rhythm wavefronts at the PVA may result in increased arrhythmogenicity and susceptibility to atrial fibrillation (AF).

Methods: Intraoperative high-density epicardial mapping of PVA (N≈450 sites, interelectrode distances: 2 mm) was performed during sinus rhythm in 327 patients (241 male [74%], 67±10 [21-84] years) with and without preoperative AF. Read More

Department of Clinical Sciences of Companion Animals, Faculty of Veterinary Medicine, Utrecht University, Yalelaan 108, 3508 TD, Utrecht, The Netherlands.

Background: Pulmonary veno-occlusive disease (PVOD) is a rare cause of pulmonary arterial hypertension (PAH) in humans and can be classified in idiopathic, heritable, drug and radiation-induced, and associated with connective tissue disease or human immunodeficiency virus infection. Recently, biallelic mutations of the EIF2AK4 gene have been discovered as a cause for an autosomal recessive form of PVOD in humans. In dogs, PAH is poorly characterized and is generally considered to be idiopathic or secondary to (for example) congenital left-to right cardiovascular shunts or heartworm disease. Read More
