The primary aim of the study is to investigate the temporal changes in plasma lipidome before and after reperfusion in patients with ST-segment elevation myocardial infarction (STEMI) and their association with myocardial injury. We found that 56% of the identified lipid species were significantly altered (corrected p< 0.05) in the first 24 h following reperfusion in patients with STEMI. Three lipid species, namely, acylcarnitine 18:2, TG 51:0, and LPC 17:1 were associated with a change in troponin concentration (delta troponin) and in-hospital cardiovascular events. Of these, acylcarnitine 18:2, and LPC 17:1 and their respective whole class levels, were significantly higher (p < 0.05) in the STEMI population than the age/sex-matched control subjects. Overall, our analyses showed a large shift in plasma lipidome in patients that undergo myocardial reperfusion. The differences found for acylcarnitines and LPC species and their association with both cardiac markers and cardiac outcomes need further validation.

Objectives: Recent research indicates that the plasma lipidome composition may undergo alterations following hemorrhagic stroke. Nevertheless, the causal inference between plasma lipidome and hemorrhagic stroke remains elusive.
Materials And Methods: Exposure data were achieved from a recent Genome-wide Association Study (GWAS) study of 179 lipid species involving 7,174 individuals, while the outcome data were obtained from the FinnGen consortium (R10), including intracerebral hemorrhage (ICH), subarachnoid hemorrhage (SAH), and non-traumatic intracranial hemorrhage (nITH).

The underlying mechanisms and diagnostic biomarkers for the progress of COVID-19 in HIV patients have not been fully elucidated. In this study, the aim is to analyze the metabolomic profiles of HIV/AIDS patients co-infected with SARS-CoV-2 and to identify biomarkers indicative of co-infection. In this study, we conducted a retrospective cohort analysis of peripheral blood samples collected from 30 HIV/AIDS patients co-infected with SARS-CoV-2 (pc group) and 30 patients without SARS-CoV-2 (nc group).

Parkinson's disease (PD) represents one of the most frequent neurodegenerative disorders for which clinically useful biomarkers remain to be identified and validated. Here, we adopted an untargeted omics approach to disclose lipidomic, metabolomic and proteomic alterations in plasma and in dermal fibroblasts of PD patients carrying mutations in TMEM175 gene. We revealed a wide dysregulation of lysosome, autophagy, and mitochondrial pathways in these patients, supporting a role of this channel in regulating these cellular processes.

Objective: Lipids are key molecules for atherosclerosis, with tight regulation mechanisms, making them potential biomarkers for disease-specific diagnostics and therapeutics. Therefore, we aim to perform a systematic literature review on lipidomic analysis in serum/plasma and plaque samples of patients with carotid atherosclerosis.
Methods: We performed a systematic review following the PRISMA guidelines on the lipidomic profile in serum/plasma and carotid artery plaques from patients with significant carotid disease by degree of stenosis in preoperative imaging and clinical presentation (symptomatic, asymptomatic, radiation-induced carotid disease).

Purpose: A comprehensive analysis of metabolites (metabolomics) has been proposed as a new strategy for analyzing liquid biopsies and has been applied to identify biomarkers predicting clinical responses or adverse events associated with specific treatments. Here, we aimed to identify metabolites associated with bortezomib (Btz)-related toxicities and response to treatment in newly diagnosed multiple myeloma (MM).
Methods: Fifty-four plasma samples from transplant-ineligible MM patients enrolled in a randomized phase II study comparing two less-intensive regimens of melphalan, prednisolone and Btz (MPB) were subjected to the lipidomic profiling analysis.
