Background: Neutrophil gelatinase-associated lipocalin (NGAL), a novel biomarker of acute kidney injury, might play a role in the development of atherosclerotic cardiovascular disease (CVD). We aimed to assess the association of circulating NGAL with CVD risk.
Materials And Methods: Plasma NGAL concentrations were measured at baseline in 5275 participants in the PREVEND prospective study. Hazard ratios (95% confidence intervals [CI]) for CVD were estimated.
Results: After a median follow-up of 8.3 years, 338 participants developed first CVD events. Plasma NGAL was weakly to moderately correlated with several CVD risk markers. There was a non-linear relationship between NGAL and CVD risk. In analyses adjusted for established risk factors, the hazard ratio (95% CI) for CVD in a comparison of the top quartile versus bottom quartiles 1-2 of NGAL values was 1.35 (1.05-1.75; P = 0.022), which was abrogated after additional adjustment for other potential confounders (mainly attributed to high sensitivity C-reactive protein) 1.20 (0.92-1.57; P = 0.176). The association was considerably attenuated following further adjustment for renal function 1.05 (0.79-1.40; P = 0.745). The association between NGAL and CVD risk did not vary importantly in relevant clinical subgroups.
Conclusion: Evidence suggests a non-linear association between NGAL and CVD risk, which is dependent on inflammation and renal function.

Article Synopsis
- The study investigates the links between Alzheimer's disease (AD) and cardiovascular diseases (CVD) in older adults by analyzing plasma proteomic biomarkers in a sample of 566 participants.
- Researchers found that 48 biomarkers were specifically associated with AD, while 46 were linked to CVD, along with 14 biomarkers showing connections for both conditions.
- The findings suggest complex relationships between cognitive decline and cardiovascular health, indicating shared biological markers and mechanisms, with the Tamm Horsfall Protein (THP) being notably associated with all three conditions (AD, MCI, and CVD).
Novel biomarkers in patients with uncontrolled hypertension with and without kidney damage.

Introduction: Estimated glomerular filtration rate (eGFR) and urine albumin/creatinine ratio (ACR) are insensitive biomarkers for early detection of hypertension-mediated organ damage (HMOD). In this nationwide cross-sectional study, we assessed potential biomarkers for early HMOD in healthy persons and patients with hypertension. We hypothesised that plasma levels of biomarkers: (1) are different between healthy controls and patients with hypertension, (2): can classify patients with hypertension according to the degree of hypertension severity.

Introduction: The burden of cardiovascular disease (CVD) is huge due to its associated morbidity, mortality and adverse socio-economic impact. Environmental pollution as a risk factor contributes significantly to the burden of CVD, especially in the low and middle income countries. One of the effective strategies to reduce CVD burden is to prevent or detect cardiovascular risk factors early in at-risk population.

Growth differentiation factor 15 (GDF-15), neutrophil gelatinase-associated lipocalin (NGAL), and ADAMTS13 have previously been implicated in the pathophysiological processes of SAH. In the present study, we aim to examine their role in the early period of SAH and their relationship to primary and secondary outcomes. Serum samples were collected at five time periods after SAH (at 24 h (D1), at 72 h (D3), at 120 h (D5), at 168 h (D7) and at 216 h (D9), post-admission) and) were measured by using MILLIPLEX Map Human Cardiovascular Disease (CVD) Magnetic Bead Panel 2.

Background: N-terminal portion of the B-type natriuretic propeptide (NT-proBNP) has potentially been shown to play an important role in the development of periodontitis and cardiovascular disease (CVD). This study evaluated the efficacy of periodontal treatment on NT-proBNP and related CVD biomarkers and explored whether subjects harboring high NT-proBNP at baseline showed increased clinical benefits with the non-surgical periodontal treatment performed with full-mouth scaling and root planing (FM-SRP) at 6-month follow-up.
Methods: Forty-eight patients with stage III periodontitis were randomized to receive minimal standard oral care (SOC) (n = 24) or FM-SRP (n = 24) protocol.
