Objective: To examine the relationship between sublingual microcirculatory measures and frailty index in those attending a kidney transplant assessment clinic.

Methods: Patients recruited had their sublingual microcirculation taken using sidestream dark field videomicroscopy (MicroScan, Micro Vision Medical, Amsterdam, the Netherlands) and their frailty index score using a validated short form via interview.

Results: A total of 44 patients were recruited with two being excluded due to microcirculatory image quality scores exceeding 10. The frailty index score indicated significant correlations with total vessel density (p < .0001, r = -.56), microvascular flow index (p = .004, r = -.43), portion of perfused vessels (p = .0004, r = -.52), heterogeneity index (p = .015, r = .32), and perfused vessel density (p < .0001, r = -.66). No correlation was shown between the frailty index and age (p = .08, r = .27).

Conclusions: There is a relationship between the frailty index and microcirculatory health in those attending a kidney transplant assessment clinic, that is not confounded by age. These findings suggest that the impaired microcirculation may be an underlying cause of frailty.

The advancements in cardiovascular imaging over the past two decades have been significant. The miniaturization of ultrasound devices has greatly contributed to their widespread adoption in operating rooms and intensive care units. The integration of AI-enabled tools has further transformed the field by simplifying echocardiographic evaluations and enhancing the reproducibility of hemodynamic measurements, even for less experienced operators.

Background: Excess fluid in the interstitium can adversely affect the microcirculation. We studied how gradual dilution of the blood plasma by crystalloid fluid influences microcirculatory variables and capillary filtration in 20 patients undergoing surgery.

Methods: Video recordings of the sublingual mucosal were made on four occasions during the surgery and compared with quasi-measurements of the capillary filtration rate using retrospective volume kinetic data collected over 5-10-minute periods during 262 infusion experiments with crystalloid fluid.

Background: Glycocalyx degradation is implicated in endothelial damage and microcirculatory dysfunction in sepsis, whereas the effectiveness of plasma syndecan-1 levels and sublingual microcirculatory parameters in evaluating sepsis's prognosis has not yet been determined. This study aims to track their dynamic changes and investigate the prognostic utility of these indexes in sepsis.

Methods: In this prospective study conducted at the First Affiliated Hospital of Sun Yat-sen University, blood samples were collected from adult surgical septic patients within 2 days after intensive care unit admission measuring plasma syndecan-1 concentrations.

Article Synopsis
  • Intestinal ischemia-reperfusion injury can lead to both large-scale (macrocirculatory) and small-scale (microcirculatory) blood flow failures, and the study aimed to test if combining a vasoconstrictor (norepinephrine) with a vasodilator (ilomedin) improves blood pressure and circulation after injury.
  • The research was conducted on 21 pigs, with three groups receiving different treatments before and after a 2-hour induced small bowel ischemia followed by reperfusion, measuring various circulatory parameters and biomarkers.
  • Results showed no significant differences in mean arterial pressure or cardiac index between the groups, but the combination therapy group had notably better microcirculation performance immediately after and two

Background: Loss of hemodynamic coherence is a phenomenon in critically ill patients. Due to inflammatory events and endothelial remodeling, macro- and microhemodynamics are decoupled from each other, resulting in microcirculatory disturbances and end organ ischemia despite adequate vital parameters. So far, quantification of perfusion of vessels with < 100 μm diameter on the intensive care unit (ICU) was regularly performed with incident darkfield (IDF) microscopy.
