Objectives: Growing evidence suggests that angiogenic vascular factors may be involved in the pathogenic mechanism of Alzheimer's disease (AD), and recently endocan has been proposed as an angiogenic biomarker. The aim of this study was to measure serum endocan levels according to the presence of depression in AD and to investigate the association among the serum endocan levels, cognitive function, and depression in these patients.
Methods: Serum endocan levels were measured in 26 AD patients with depression, 29 AD patients without depression, and 29 healthy controls using an enzyme-linked immunosorbent assay kit. The Mini-Mental State Examination-Korean version (MMSE-KC) and the Korean version of the Geriatric Depression Scale-Short Form (SGDS-K) were used to evaluate cognitive function and depressive symptoms, respectively.
Results: Serum endocan levels were significantly lower in AD patients with depression than in AD patients without depression or healthy controls. Serum endocan levels were negatively correlated with SGDS-K scores but not with MMSE-KC scores in AD patients.
Conclusions: This study suggests that serum endocan levels might be associated with depression in AD. Future studies are needed to investigate the pathophysiological mechanisms or the role of endocan in AD with depression.

Introduction: Despite the efficacy and safety of SARS-CoV-2 vaccines, inflammatory and/or thrombotic episodes have been reported. Since the impact of COVID-19 vaccines on the endothelium remains uncertain, our objective was to assess endothelial activation status before and 90 days after the third dose of the BNT162b2 mRNA COVID-19 vaccine.
Methods: A prospective longitudinal study was conducted at University General Hospital of Albacete, involving 38 healthy health-care workers.

Introduction: The COVID-19 pandemic has promoted an intensive investigation into the pathophysiological mechanisms of SARS-CoV-2 infection, risk factors, and its impact on disease severity. Vitamin D has generated significant attention for its potential role in viral prevention and immune defense due to its pleiotropic functions, including immunomodulation and antimicrobial effects. This study aimed to assess serum 25(OH)D3 levels in patients with COVID-19 compared to those with other viral respiratory infections and to evaluate associations of vitamin D levels with symptomatology, clinical characteristics, presence of comorbidities and laboratory investigation.

Background & Aims: Acute-on-chronic liver failure is a syndrome characterized by organ failure and high short-term mortality. The lack of reliable biomarkers for the early detection of acute-on-chronic liver failure is a significant challenge. Endothelial dysfunction plays a key role in the development of organ failure.

Article Synopsis
- Endothelial-cell-specific molecule-1 (ESM-1), also known as endocan, is identified as a significant biomarker for inflammation and cardiovascular risk in COVID-19 patients, particularly in the context of Multisystem Inflammatory Syndrome in children (MIS-C).
- In a study comparing ESM-1 levels between MIS-C patients and healthy controls, MIS-C patients showed significantly higher levels of ESM-1, suggesting its potential diagnostic value.
- The research indicates that ESM-1 not only correlates with other inflammatory markers but is also associated with cardiac complications, highlighting its role in assessing cardiovascular risks in MIS-C patients and aiding in treatment strategies.
