Point-of-care ultrasound can support volume and hemodynamic assessment by combining cardiac views, lung findings and venous examination. Rather than relying on a single measurement such as inferior vena cava diameter, integrated ultrasound assessment can identify pulmonary congestion, ventricular dysfunction, pericardial effusion and other causes of shock or dyspnea. For internists, the practical advantage is that ultrasound can be repeated as the patient's physiology changes. However, POCUS is operator-dependent and should not be interpreted as a stand-alone diagnostic test. Structured training and competency assessment are therefore important. In fluid management, ultrasound findings should be integrated with blood pressure, perfusion, urine output, lactate and clinical trajectory. The evidence supports POCUS as an extension of the physical examination rather than a replacement for formal echocardiography or radiology. This approach fits the APICON emphasis on practical bedside skills because it links imaging directly to clinical reasoning and management decisions.

Recent research defines ferro-aging as a conserved iron-lipid axis driving organ decline across primates. Age-related iron dyshomeostasis stimulates ACSL4-mediated lipid peroxidation, promoting cellular senescence. Notably, vitamin C directly inhibits ACSL4, suppressing phospholipid oxidation and multi-organ decay.
