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. The amount of each lipid metabolite in plasma obtained prior to MPB therapy was compared to toxicity grades and responses to MPB therapy.
Results: High levels of 7 phospholipids (4 lysophosphatidylcholines and 3 phosphatidylcholines) were observed in cases with Btz-induced ≥ grade 2 peripheral neuropathy (BiPN) (n = 11). In addition, low levels of 3 fatty acids (FAs)-FA (18:2), FA (18:1), and FA (22:6)-were observed in patients who developed severe skin disorders ≥ grade 2 (n = 10). No metabolite significantly associated with treatment response was identified.
Conclusion: We conclude that levels of specific plasma lipid metabolites are associated with the severity of BiPN and skin disorders in patients with MM. These metabolites may serve as candidate biomarkers to predict Btz-induced toxicity in patients with MM before initiating Btz-containing therapy.

Meat lipids are determinants of the nutritional, sensory and physiological qualities of meat, encompassing triglycerides, phospholipids, cholesterol and bioactive compounds. These lipids provide essential fatty acids, including omega-3 and omega-6 polyunsaturated fatty acids, critical for metabolic regulation, inflammation control and cognitive health. However, the dual role of meat lipids as essential nutrients and potential contributors to health risks, such as cardiovascular disease and oxidative stress, necessitates a nuanced understanding.

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).

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).

This study investigated the fatty acids (FA) profile of 54 actinomycete strains isolated from marine sediments collected off the Portugal continental coast, specifically from the Estremadura Spur pockmarks field, by GC/MS. Fatty acid methyl esters (FAMEs) were prepared from the ethyl acetate lipidic extracts of these strains and analyzed by gas chromatography-mass spectrometry (GC/MS), with FA identification performed using the NIST library. The identified FAs varied from C12:0 to C20:0, where 32 distinct FAs were identified, including 7 branched-chain fatty acids (BCFAs), 9 odd-chain fatty acids (OCFAs), 8 monounsaturated fatty acids (MUFAs), 6 saturated fatty acids (SFAs), 1 polyunsaturated fatty acid (PUFA), and 1 cyclic chain fatty acid (CCFA).
