Article Abstract
Door-to-balloon (DTB) time significantly affects the prognosis of patients with ST-segment elevation myocardial infarction (STEMI). The effects of temporal differences in emergency department (ED) arrival time on DTB time and on different segments of DTB time remain inconclusive. Therefore, we performed a retrospective study in a tertiary hospital between January 2013 and December 2021 and investigated the relationship between a patient's arrival time and both their DTB time and different segments of their DTB time. Of 732 STEMI patients, 327 arrived during the daytime (08:01-16:00), 268 during the evening (16:01-24:00), and 137 at night (00:01-08:00). Significantly higher odds of delay in DTB time were observed during the nighttime (adjusted odds ratio (aOR): 2.87; 95% confidence interval (CI): 1.50-5.51, = 0.002) than during the daytime. This delay was mainly attributed to a delay in cardiac catheterization laboratory (cath lab) activation-to-arrival time (aOR: 6.25; 95% CI: 3.75-10.40, < 0.001), particularly during the 00:00-04:00 time range. Age, sex, triage level, and whether patients arrived during the COVID-19 pandemic also had independent effects on different segments of DTB time. Further studies are required to investigate the root causes of delay in DTB time and to develop specific strategies for improvement.

Background: ST-segment elevation myocardial infarction (STEMI) demands aggressive and rapid medical intervention. Delays in Door-to-balloon time (DTB) of more than 90 min cause progressive damage to the cardiac tissue and require immediate medical intervention, including percutaneous coronary intervention (PCI). Nurses and doctors in STEMI management face several challenges that result in a delay in DTB time.

Background: The Saudi Acute Myocardial Infarction Registry (STARS) program aims to evaluate the clinical characteristics, management, and outcomes of a representative sample of patients with acute myocardial infarction (AMI) in Saudi Arabia. This second phase evaluates temporal changes in patient care, demographics, and the management benchmarks for AMI.
Methods And Findings: We created a 5-year recurring, multi-center prospective registry that utilizes a snapshot design in 50 hospitals from various healthcare sectors in Saudi Arabia.

Hydrogen sulfide (HS) plays a crucial role in the regulation of various physiological processes within living organisms, including cell signaling, vascular tone modulation, and the inflammatory response. The real-time detection and visualization of HS levels in practical samples hold significant importance for biological analysis. In this study, 3-(benzo[d]thiazol-2-yl)-5-bromo-2-(2,4-dinitrophenoxy)benzaldehyde (DTBH) was designed and synthesized based on the mechanism of excited state intramolecular proton transfer (ESIPT).

Objectives: To analyse patient profiles, transportation patterns and time delays in ischaemic time and door-to-balloon (DTB) time and evaluate the effect of these delays on in-hospital mortality among patients undergoing primary percutaneous coronary intervention (P-PCI) for ST-segment elevation myocardial infarction (STEMI) at a tertiary care hospital in Colombo.
Design: Retrospective observational study.
Setting: Tertiary care hospital specialising in STEMI treatment, located in Sri Lanka.
Use of dimensionless time and water volume to estimate subsurface drip irrigation wetted zone in different soil textures.

Accurate estimation of the geometric characteristics of the wetted zone, including depth, height, and width, is crucial for optimizing subsurface drip irrigation (SDI) system design and management. This study evaluated and compared two dimensionless analysis models-based on dimensionless time and dimensionless water volume-for predicting the wetted zone parameters in three soil textures: sandy loam, loam, and clay loam. The dimensionless time-based (DTB) model incorporated parameters such as initial soil water content (ISWC), dripper flow rate, and alpha value (the reciprocal of the macroscopic length scale in hydraulic conductivity function), while the dimensionless water volume-based (DWVB) model used ISWC, saturated hydraulic conductivity, dripper flow rate, and installation depth.
