Background: High blood pressure (BP) is a major risk factor for cardiovascular disease. The triglyceride-glucose (TyG) index is a useful tool for identifying insulin resistance at an early stage and has been proposed as a cost-effective predictor for hypertension. However, available studies are limited. This study aims to investigate the association between the TyG index and BP. Methods: Retrospective hospital data of a large cohort (n=1596) of adults aged ≥ 18 in Saudi Arabia were analyzed. The TyG index was calculated. Lipid markers, systolic BP (SBP), diastolic BP (DBP), and body mass index (BMI) were included. Results: Across quartiles of the TyG index, SBP was significantly higher in those with higher vs lower TyG (p< 0.03). No significant association was observed for DBP. A 2-SD higher SBP was significantly associated with a TyG difference of 1.7 (95% CI: 0.1, 3.3). In subgroup analysis, the relationship prevailed in females only [1.8 (95% CI: 0.3, 3.3)]. Across BMI categories (normal, overweight, obesity), the association between SBP and TyG was observed in participants with obesity only. Conclusions: The TyG index may act as a cost-effective predictive marker for high blood pressure, especially among specific subgroups. Future prospective studies are needed to confirm this relationship. [ABSTRACT FROM AUTHOR]

Introduction: Ethical dilemmas in healthcare, particularly in emergency medical services (EMS), present significant challenges for healthcare workers (HCWs), necessitating a profound understanding of ethics and decision-making. This study assesses the ethical awareness and practices among HCWs in emergency departments of tertiary hospitals in Saudi Arabia, aiming to identify areas of strength and opportunities for improvement. Methods: A cross-sectional survey was conducted among 256 HCWs, including physicians, nurses, and administrative staff, in emergency departments across tertiary hospitals in Riyadh, Saudi Arabia. The questionnaire evaluated participants' knowledge of healthcare ethics, their experiences with ethical dilemmas, and the sources from which they derived their ethical understanding. Results: The majority of participants exhibited a commendable level of ethical knowledge and practice, with frequent encounters of ethical or legal issues highlighting the pervasive nature of ethical challenges in emergency healthcare settings. Key sources of ethical knowledge included experiential learning and academic lectures, with a notable emphasis on practical experience. Despite the satisfactory level of ethical awareness, areas requiring further educational focus were identified, emphasizing the need for enhanced ethics training tailored to the emergency medical context. Discussion: The findings underline the critical importance of incorporating ethics into the core of healthcare education and ongoing professional development for HCWs. Establishing a culture of continuous ethical dialogue and learning is essential for fostering patient-centered care and making informed ethical decisions in the fast-paced environment of emergency services. The study advocates for revising current ethics training programs to ensure they are comprehensive, relevant, and accessible, preparing HCWs to effectively address both current and future ethical challenges.
