Application value of split-bolus contrast injection combined with dual-energy CT scanning technology in pediatric CTU imaging.
Eur J Radiol

Electronic address:
Objective: To explore the clinical value of combining split-bolus contrast injection with dual-energy CT(DECT) scanning technology in pediatric computed tomography urography (CTU) imaging.
Methods: A total of 128 children aged 0-17 years were prospectively selected and randomly assigned to three groups: A, B, and C. For Group A, a high-pitch flash mode was employed, where a single bolus of contrast agent was followed by four-phase scanning (noncontrast, cortex, medulla, and excretory phases).
An exploratory survey assessing the determinants of heat stress and heat strain in the Canadian mining industry from the worker's perspective.

With mines extending deeper and rising surface temperatures, workers are exposed to hotter environments. This study aimed to characterize heat stress and strain in the Canadian mining industry and evaluate the utility of the Heat Strain Score Index (HSSI), combined with additional self-reported adverse health outcomes. An exploratory web-based survey was conducted among workers ( = 119) in the Canadian mining industry.

Background: Laparoscopic surgery training is a demanding process requiring technical and nontechnical skills. Surgical training has evolved from traditional approaches to the use of immersive digital technologies such as virtual, augmented, and mixed reality. These technologies are now integral to laparoscopic surgery training.

Objective: Loss of function of the phospholipid scramblase (PLS) TMEM16F results in Scott Syndrome, a hereditary bleeding disorder generally attributed to intrinsic platelet dysfunction. The role of TMEM16F in endothelial cells, however, is not well understood. We sought to test the hypothesis that endothelial TMEM16F contributes to hemostasis by measuring bleeding time and venous clotting in endothelial-specific knockout (ECKO) mice.

Background: Computed tomography angiography of the head (CTAH) is not routinely obtained during the initial evaluation of patients with traumatic intracranial hemorrhage (ICH); however, it is useful for diagnosing vascular pathologies that may have led to the bleed. The aims of this study were to identify traumatic ICH patient characteristics on presentation that are associated with positive CTAH findings to elucidate which ones should prompt a CTAH and compare outcomes of patients with positive and negative CTAH findings.
Methods: This is a retrospective cohort study of 522 patients who had blunt traumatic ICH and subsequently received CTAH between January 1, 2017, and January 1, 2022.
