This Special Issue delves into the nexus of pop politics and popular culture, focusing on the employment of cultural symbols and strategies in communication. The articles included discuss the evolution of politainment in the digital age, where social media platforms amplify political messages by blending entertainment with political discourse. The authors highlight concerns regarding the devaluation of political information and its impact on democratic quality. Furthermore, the issue examines how pop politics encourages civic engagement and political awareness, utilizing various mediums for collective action, while cautioning against the potential adverse effects on public discourse. Ultimately, this Special Issue provides multidisciplinary perspectives on the intersection of politics and entertainment, its implications for democracy, and the evolving landscape of political communication.

One of the main factors that influences the fertility of cattle in grazing systems in hot tropical climates is heat stress. The objective of this study was to evaluate the effect of season, breed, hormonal and physiological condition on the quantity and quality of cumulus-oocyte complexes (COCs) and embryos produced in vitro, from Romosinuano (RM) and Tropical Milking (TM) donors. Three ovum pick-up and in vitro fertilization (OPU-IVF) were performed, one per season: hot dry (HD; 10, 10), hot humid (HH; 9, 9) and fresh dry (FD; 7, 10) in RM and LT donors. Serum levels of cortisol, insulin and glucose were measured, in addition to heart rate (HR), respiratory rate (RR) and rectal temperature (RT). Effect of season x genotype interaction ( p ≤ 0.05) was observed in all COC variables and only in cleavage embryos (CLI) ( p ≤ 0.05). Body weight (BW) affected all COC variables ( p ≤ 0.01), except unviable (UNV) although affected degenerated embryos (DEG) ( p ≤ 0.01) and total blastocysts (BLAST) ( p ≤ 0.01). Cow age only affected viable COCs (VIAB) ( p ≤ 0.05), code one blastocysts (BC1) and BLAST ( p ≤ 0.01). Cortisol affected total COCs (COCsT), VIAB and total matured in vitro (TMIV) ( p ≤ 0.01), as well as CLI, BC1 ( p ≤ 0.01) and BLAST ( p ≤ 0.05). Insulin affected COCsT ( p ≤ 0.01), UNV ( p ≤ 0.05), denuded oocytes (DE) ( p ≤ 0.01), BC1 and code two blastocysts (BC2) ( p ≤ 0.01). Glucose affected all COC variables ( p ≤ 0.01), except UNV and all embryo variables except BC2. HR affected COCsT, DE, TMIV ( p ≤ 0.01), CLI, BLAST and DEG ( p ≤ 0.05). RR affected COCsT, UNV, VIAB, CLI ( p ≤ 0.05), BC1, BLAST and DEG ( p ≤ 0.01). RT only affected DE, VIAB ( p ≤ 0.01) and BLAST ( p ≤ 0.05). The seasonal climatic year variation of Veracruz and changes in physiological and hormonal variables have diverse effects on the cumulus-oocyte complexes and embryos produced by RM and TM donors.

Objective: To analyze the prevalence of no-reflow and the 30-day mortality in a university center in a middle-income country., Method: We analyzed 2463 patients who underwent primary PCI from January 2006 to December 2021. The outcome measure was 30-day mortality., Results: Of a total of 2463 patients, no-reflow phenomenon was found in 413 (16.8%) patients, 30-day mortality was 16.7 vs. 4.29% (p < 0.001). Patients with no-reflow were older 60 (53-69.5) vs. 59 (51-66) (p = 0.001), with a higher delay in onset of symptom to emergency department arrival 270 vs. 247 min (p = 0.001). No-reflow patients also had had fewer previous myocardial infarction, 11.6 vs. 18.4 (p = 0.001) and a Killip class > 1, 37 vs. 26% (p < 0.001). No-reflow patients were more likely to have an anterior myocardial infarction (55.4 vs. 47.8%; p = 0.005) and initial TIMI flow 0 (76 vs. 68%; p < 0.001)., Conclusion: No-reflow occurred in 16.8% of STEMI patients undergoing primary PCI and was more likely with older age, delayed presentation, anterior myocardial infarction and Killip class > 1. No-reflow was associated with a higher mortality at 30-day follow-up., (Copyright: © 2024 Permanyer.)
