Periprocedural Use of Heparin and Other Factors Contributing to the Patency of the Radial Artery Following Diagnostic Coronary Angiography.

Diagnostic angiography of coronary arteries is one of the most common procedures in invasive cardiology and is mainly performed via the radial artery. Rapid improvements in the quality of the equipment and operator's experience have changed the landscape of this procedure. In this study, 284 patients were analyzed to determine whether heparin administration should be a necessity for all patients to prevent radial artery occlusion (RAO).

Intensity of pain during coronary interventions via the radial artery.

Introduction: Radial access reduces vascular complications compared to femoral access. Various factors may influence the patient's pain during coronary intervention.

Aim: To assess what clinical and periprocedural factors affect discomfort and pain intensity during angiography via the radial artery without use of spasmolytics.

Associations of air pollution with acute coronary syndromes based on A/B/AB versus O blood types: case-crossover study.

Short-term exposure to air pollutants may contribute to an increased risk of acute coronary syndrome (ACS). This study assessed the role of short-term exposure to fine particulate matter (PM) as well as fine and coarse PM (PM) air pollution in ACS events and the effect of blood groups on this phenomenon. A retrospectively collected database of 9026 patients was evaluated.

Machine learning in the diagnosis of asthma phenotypes during coronavirus disease 2019 pandemic.

Background: During the coronavirus disease 2019 (COVID-19) pandemic, it has become a pressing need to be able to diagnose aspirin hypersensitivity in patients with asthma without the need to use oral aspirin challenge (OAC) testing. OAC is time consuming and is associated with the risk of severe hypersensitive reactions. In this study, we sought to investigate whether machine learning (ML) based on some clinical and laboratory procedures performed during the pandemic might be used for discriminating between patients with aspirin hypersensitivity and those with aspirin-tolerant asthma.

Polycystic Ovary Syndrome: Personality and Temperamental Characteristics.

Polycystic ovary syndrome (PCOS) is a common gynaecological/endocrine disorder that affects 5%-10% of women of reproductive age. Its association with psychiatric conditions is well known. This study aimed to evaluate personality, temperamental, and stress-related characteristics among PCOS patients by comparing them with a control group.
