Blood pressure cut-offs to diagnose impending hypertensive emergency depend on previous hypertension-mediated organ damage and comorbid conditions.

Background Hypertensive emergencies (HTN-E) are important due to a high risk of mortality. However, a sudden increase in blood pressure (BP) can damage target organs before the BP reaches cut-offs to diagnose HTN-E. We (i) analyse HTN guidelines for recommendations of treatment individualization, such as adjusting BP cut-offs for hypertensive urgency or impending HTN-E according to patient's susceptibility to complications (because of previous hypertension-mediated organ damage [HMOD], cardiovascular events and comorbid conditions), and (ii) provide a rationale for the inclusion of patient's susceptibility in protocols for treatment of acute HTN-E.

Less Known but Clinically Relevant Comorbidities of Atrial Fibrillation: A Narrative Review.

Background: The important risk factors for atrial fibrillation (AF) in the general population are not always equally important in specific and relatively prevalent diseases.

Pulmonary embolism bleeding score index (PEBSI): A new tool for the detection of patients with low risk for major bleeding on thrombolytic therapy.

Background: Estimation of bleeding risk is an unmet need for individualized therapy in acute pulmonary embolism (PE) patients with increased mortality risk.

Methods: We analyzed the association between various patients' characteristics and occurrence of major bleeding (MB) according to the modified International Society of Thrombosis and Hemostasis (ISTH) criteria ("overt" bleeding is the only modification from the original criteria) at 7 days from admission to the hospital and thrombolytic therapy with a tissue-plasminogen activator (tPA). Pulmonary embolism bleeding score index (PEBSI) was created using multivariate regression analyses, and finely, dichotomous index was used for the discrimination of patients with low risk for MB from those with high risk.

Impact of ellagic acid application on doxorubicin-induced cardiovascular toxicity model.

Doxorubicin is an anticancer agent that is commonly used to treat a number of tumors and is associated with acute and chronic changes of the cardiovascular system. Ellagic acid has strong free radical scavenging capacity, neuroprotective and hepatoprotective effects, and is known to protect against changes occurring due to diabetes, cardiovascular diseases, and cancer. Twenty-four Wistar rats were divided in four groups: control group received saline, doxorubicin group received doxorubicin in a single dose of 20 mg/kg, ellagic acid group received ellagic acid in a dose of 4 mg/kg, and doxorubicin + ellagic acid group received doxorubicin and ellagic acid in same doses as in previous groups.

Elevated Serum Ferritin Levels Are Predictive of Renal Function Recovery among Patients with Acute Kidney Injury.

Oxidative stress (OS) frequently contributes to the development of acute kidney injury (AKI). Iron can promote oxidative stress and tissue injury by catalyzing free reactive oxygen species (ROS) generation and increasing the steady-state concentration of these potent oxidants. The anticipated role of ferritin is to protect from OS by sequestering iron and limiting its involvement in reactions that generate ROS.
