Changes in sympathoadrenal function and cardiovascular deconditioning have long been recognized as a feature of the physiological adaptation to microgravity. The deconditioning process, coupled with altered hydration status, is thought to significantly contribute to orthostatic intolerance upon return to Earth gravity. The cardiovascular response to stimulation by sympathomimetic agents before, during, and after exposure to simulated microgravity was determined in healthy volunteers equilibrated on normal or high sodium diets in order to further the understanding of the deconditioning process.

Introduction: Adults with relapsed or refractory Philadelphia chromosome-positive B-cell precursor acute lymphoblastic leukaemia (R/R Ph+ BCP-ALL) have a dismal outcome. Blinatumomab as a single agent has shown activity in R/R Ph- BCP-ALL, and second or third-generation tyrosine kinase inhibitors (TKIs) can produce high remission rates in Ph+ leukaemias. We aimed to assess the activity of blinatumomab and TKI in combination with intensive chemotherapy in the relapsed or refractory setting.

Background To address the growing burden of hypertension and related diseases, Nigeria seeks to reduce excess dietary sodium through policymaking. The current study aims to describe the levels and sources of dietary sodium intake among Nigerian adults to inform targeted policies for reducing sodium intake. Methods From June 2023 to July 2023, adults aged 18 to 70 years old were recruited from the Federal Capital Territory, Kano States, and Ogun States to participate in a population-based, cross-sectional non-communicable diseases survey.

The risk of cardiovascular disease differs among various ethnic groups, highlighting disparities in cardiovascular health among different populations. While multiple studies from other countries have looked at changes in physiological parameters during autonomic function tests like isometric handgrip and cold pressor tests, no correlational research has been done in Saudi Arabia. This lacuna underscores the importance of examining the relationship between cardiorespiratory parameters in young Saudi Arabian individuals during these tests.

Cardiometabolic diseases (CMD) are leading causes of death and disability worldwide, with complex pathophysiological mechanisms in which inflammation plays a crucial role. This review aims to elucidate the molecular and cellular mechanisms within the inflammatory microenvironment of atherosclerosis, hypertension and diabetic cardiomyopathy. In atherosclerosis, oxidized low-density lipoprotein (ox-LDL) and pro-inflammatory cytokines such as Interleukin-6 (IL-6) and Tumor Necrosis Factor-alpha (TNF-α) activate immune cells contributing to foam cell formation and arterial wall thickening.
