We examined whether specific plasma lipidomic signatures are related to pericoronary adipose tissue (PCAT) inflammation and coronary artery disease (CAD) burden.MethodsThis cross-sectional analysis included 176 T2DM participants from the GADA study. PCAT inflammation was measured by the fat attenuation index (FAI), CAD burden by Gensini/SYNTAX scores and plasma lipid species by targeted LC-MS. Multivariable regression were used to identify lipid species associated with FAI and CAD burden. For lipid species linked to both, mediation analyses were performed.ResultsWe quantified 660 lipid molecular species across 20 classes. Five species were associated with FAI: sphingomyelin (SM) (34:4), phosphatidylcholines (PC) (16:0/20:4), Lysophosphatidylethanolamine (LPE) (18:1), LPE (20:4), and LPE (18:2). The three LPE species remained independently associated with both Gensini and SYNTAX scores after adjustment for clinical risk factors, conventional lipid measures, triglycerides, and hsCRP.

The hemoglobin glycation index (HGI), reflecting the discrepancy between observed and predicted glycated hemoglobin, has emerged as a marker of interindividual variation in glycation beyond conventional HbA1c. However, the prognostic significance of HGI in hospitalized patients with HF remains unclear.MethodsIn this retrospective cohort study, we analyzed data from the MIMIC-IV database and included 3,470 adult patients hospitalized with HF. HGI was calculated as the difference between measured HbA1c and predicted HbA1c derived from fasting plasma glucose, and participants were categorized into quartiles. The primary outcome was 365-day all-cause mortality, and the secondary outcome was 30-day all-cause mortality. Kaplan-Meier survival analysis, restricted cubic spline modeling, multivariable Cox regression, and subgroup analyses were performed to evaluate the association between HGI and mortality.ResultsAmong the 3,470 included patients, 837 (24.1%) died within 365 days after discharge. Restricted cubic spline analysis demonstrated a predominantly L-shaped association between HGI and both 30-day and 365-day all-cause mortality, with excess mortality risk mainly concentrated at low HGI values. In multivariable Cox models, compared with the lowest quartile, higher HGI quartiles were associated with significantly lower risks of both short-term and long-term mortality, supporting the particular vulnerability of patients with extremely low HGI. Subgroup analyses generally supported the robustness of these findings, although a significant interaction with diabetes status was observed for 365-day mortality.ConclusionsHGI was independently associated with short-term and long-term all-cause mortality in hospitalized patients with HF, with a predominantly L-shaped pattern observed. Excess mortality risk was mainly concentrated at low HGI values.

Thirty-seven studies met inclusion criteria, predominantly observational and focused on type 2 diabetes. Inflammatory markers were more frequently associated with depressive symptoms in type 2 diabetes than in type 1. CRP/hs-CRP was the most commonly studied biomarker and was often positively associated with depressive symptoms, while composite immune-metabolic indices reflected depressive symptom burden across studies. In contrast, findings for individual cytokines, including IL-6 and TNF-α, were heterogenous and appeared dependent on adiposity, metabolic health, or vascular comorbidity. Evidence in type 1 diabetes was less uniform, with studies suggesting involvement of vascular, lipid-associated, or non-classical inflammatory pathways. Sex appeared to modify inflammation and depression associations, although patterns varied across biomarkers and study populations.
