Induction of Erythropoietin by dietary Medium-Chain Triacylglycerol in Humans.
Am J Physiol Endocrinol Metab

Erythropoietin (EPO) is pivotal in regulating red blood cell (erythrocyte) concentrations and is primarily synthesized in the kidney. Recent research has unveiled a possible link between elevated circulating concentrations of ketone bodies (KB) and circulating EPO concentrations, however, it is not known whether nutritionally induced endogenous ketogenesis can be a stimulus to induce EPO in humans. Therefore, this study aimed to assess whether acute and chronic intake of medium-chain fatty acid (MCFA)-containing triacylglycerol (MCT), which rapidly enhances endogenous circulating KB, would elevate circulating EPO concentrations in humans, as indicated by prior work with exogenous KB administration.

Am J Hematol

Patients with chronic inflammation are burdened with anemia of inflammation (AI), where inflammatory cytokines inhibit erythropoiesis, impede erythropoietin production, and limit iron availability by inducing the iron regulator hepcidin. High hepcidin hinders iron absorption and recycling, thereby worsening the impaired erythropoiesis by restricting iron availability. AI management is important as anemia impacts quality of life and potentially affects morbidity and mortality.

In renal vasculitis, luminal narrowing can reduce blood flow and activate the renin-angiotensin-aldosterone system, causing renovascular hypertension. We present the case of a 47-year-old man with previous intestinal tuberculosis and episodes of lumbar pain, tender erythematous nodules and arthralgias. He had grade 3 hypertension, unresponsive to treatment, with left ventricular concentric hypertrophy and chronic kidney disease.

Background: Fluid management is a crucial critical care component, influencing outcomes such as organ function, renal integrity, and survival in critically ill patients. Recent evidence suggests that balanced crystalloids may offer advantages over isotonic saline, particularly in reducing the risk of acute kidney injury (AKI) and other complications. This study aimed to evaluate the impact of balanced crystalloids versus isotonic saline on clinical outcomes in the intensive care unit (ICU), focusing on AKI, renal replacement therapy (RRT), and mortality.

Acute Medicine, Portsmouth Hospitals University NHS Trust, Portsmouth, GBR.
Cardiology, a high-acuity medical specialty, has traditionally emphasised technical expertise, often overshadowing the critical role of non-technical skills (NTS). This imbalance stems from the historical focus on procedural competence and clinical knowledge in cardiology training and practice, leaving a significant gap in the development of crucial interpersonal and cognitive abilities. However, emerging evidence highlights the significant impact of NTS on patient outcomes, team dynamics, and overall healthcare efficiency.
