Background: Endothelial glycocalyx (EG) degradation occurs in septic humans and EG products can be used as biomarkers of endothelial injury. Information about EG biomarkers and their association with disease severity is lacking in hospitalized foals.
Objectives: Measure serum syndecan-1 (SDC-1), heparan sulfate (HS), angiopoietin-2 (ANG-2), aldosterone (ALD), and plasma atrial natriuretic peptide (ANP) concentrations and to determine their association with disease severity and death in hospitalized foals.
Animals: Ninety foals ≤3 days old.
Methods: Prospective, multicenter, longitudinal study. Foals were categorized into hospitalized (n = 74; 55 septic; 19 sick nonseptic) and 16 healthy foals. Serum ([SDC-1], [HS], [ANG-2], [ALD]) and plasma (ANP) were measured over 72 hours using immunoassays.
Results: Serum ([SDC-1], [HS], [ANG-2], [ALD]) and plasma (ANP) were significantly higher in hospitalized and septic than healthy foals (P < .05). Serum (ANG-2) and plasma (ANP) were significantly higher in hospitalized nonsurvivors than in survivors (P < .05). On admission, hospitalized foals with serum (HS) > 58.7 ng/mL had higher odds of nonsurvival (odds ratio [OR] = 6.1; 95% confidence interval [CI] = 1.02-36.7). Plasma (ANP) >11.5 pg/mL was associated with the likelihood of nonsurvival in hospitalized foals (OR = 7.2; 95% CI = 1.4-37.4; P < .05). Septic foals with serum (ANG-2) >1018 pg/mL on admission had higher odds of nonsurvival (OR = 6.5; 95% CI =1.2-36.6; P < .05).
Conclusion And Clinical Importance: Critical illness in newborn foals is associated with EG degradation and injury, and these biomarkers are related to the severity of disease on admission and the outcome of sick foals.

Historically, the paradigm for all maladies was associated with an imbalance of the 4 humors: blood, black bile, yellow bile, and phlegm. Although our understanding of disease has evolved significantly since the time of Hippocrates, a similar cornerstone of inpatient and ambulatory care involves understanding and correcting imbalances of volume. The kidneys are the principal organs controlling extracellular volume, capable of both sensing and altering salt retention through multiple redundant pathways, including the sympathetic nervous system and the renin-angiotensin-aldosterone system.

Maintaining the physiological function of the vascular endothelium and endothelial glycocalyx is crucial for the prevention of cardiovascular disease, which is one of the leading causes of morbidity and mortality worldwide. Damage to these structures can lead to atherosclerosis, hypertension, and other cardiovascular problems, especially in individuals with risk factors such as diabetes and obesity. Endothelial dysfunction is associated with ischemic disease and has a negative impact on overall cardiovascular health.

Circulating lactate is a critical biomarker for sepsis-induced acute lung injury (S-ALI) and is strongly associated with poor prognosis. However, whether elevated lactate directly promotes S-ALI and the specific mechanism involved remain unclear. Here, this work shows that lactate causes pulmonary endothelial glycocalyx degradation and worsens ALI during sepsis.

Article Synopsis
- This study investigated eye and small blood vessel issues in patients who experienced symptoms after recovering from COVID-19, analyzing 44 patients mostly around 47 years old.
- Using advanced imaging techniques, researchers found significant retinal abnormalities, including hyperreflective dots and areas of capillary non-perfusion, indicating compromised blood flow.
- The results suggest that these retinal changes are linked to reduced capillary density, highlighting the importance of microvascular damage instead of just lasting problems with a protective layer around blood vessels.

A dysregulated immune response is associated with an excessive release of cytokines that can lead to systemic vasoplegia and vasoplegic shock with the development of multiorgan failure that is associated with an increased risk of dying. Under physiological circumstances, the endothelium and the glycocalyx are responsible for maintaining vascular tone, capillary permeability, and hemostasis, and controlling inflammation. In hyperinflammation, the endothelium and glycocalyx become damaged due to the excessive production of certain toxic proteins, along with an overwhelming release of cytokines.
