A comparison of the effects of ticagrelor and clopidogrel in patients with acute ST-segment elevation myocardial infarction: a systematic review and meta-analysis of randomized clinical trials.

Background: Rupture of unstable coronary atherosclerotic plaque leads to acute ST-segment elevation myocardial infarction (STEMI). Dual anti-platelet therapy is one of the main treatments, and the combination of Aspirin and Clopidogrel is recognized as the standard oral regimen in most cases. Ticagrelor is a new generation of P2Y12 receptor inhibitors.

Molecular pathways and biological roles of melatonin and vitamin D; effects on immune system and oxidative stress.

Melatonin and vitamin D are associated with the immune system and have important functions as antioxidants. Numerous attempts have been made to identify up to date activities of these molecules in various physiological conditions. The biosynthetic pathways of melatonin and vitamin D are correlated to sun exposure in an inverse manner.

Grandiose narcissism, unfounded beliefs, and behavioral reactions during the COVID-19 pandemic.

A theoretical perspective on grandiose narcissism suggests four forms of it (sanctity, admiration, heroism, rivalry) and states that these forms conduce to different ways of thinking and acting. Guided by this perspective, we examined in a multinational and multicultural study (61 countries; N = 15,039) how narcissism forms are linked to cognitions and behaviors prompted by the COVID-19 pandemic. As expected, differences in cognitions and behaviors across narcissism forms emerged.

Effects of wearing medical gowns at different temperatures on the physiological responses of female healthcare workers during the COVID-19 pandemic.

Background: Using medical gowns with high protection against COVID-19 among healthcare workers (HCWs) may limit heat exchange, resulting in physiological challenges.

Objective: This study aimed to compare the physiological and neurophysiological responses of female HCWs when using two typical medical gowns at different temperatures during the COVID-19 pandemic.

Methods: Twenty healthy female HCWs participated in this study.
