Plasma Metabolic and Inflammatory Protein Signatures in Psychiatric Disorders.

Psychiatric disorders, particularly schizophrenia (SCZ), bipolar disorder (BD), and schizoaffective disorder (SAD), present significant diagnostic challenges. Current diagnostic methods rely on clinical observation and self-reported symptoms, leading to under-diagnosis and delayed treatment. To address this gap, we applied mass spectrometry-based metabolomic profiling and targeted analysis of inflammatory proteins to plasma samples from patients versus controls, aiming to uncover disease-related molecular patterns and enhance our understanding of the underlying pathophysiology of these complex disorders.

Deciphering metabolic shifts in Gaucher disease type 1: a multi-omics study.

Gaucher disease (GD), an autosomal recessive lysosomal disorder, primarily affects the lysosomal enzyme β-glucocerebrosidase (GCase), leading to glucosylceramide accumulation in lysosomes. GD presents a wide spectrum of clinical manifestations. This study deploys immune-based proteomics and mass spectrometry-based metabolomics technologies to comprehensively investigate the biochemical landscape in 43 deeply phenotyped type 1 GD patients compared to 59 controls.

Lysosphingolipid Quantitation in Plasma and Dried-Blood Spots Using Targeted High-Resolution Mass Spectrometry.

Background: Sphingolipidoses are rare inherited metabolic diseases belonging to lysosomal diseases. Early and accurate diagnosis is crucial for effective management and treatment. In this study, we aimed to develop a robust method to accelerate the diagnosis of these sphingolipidoses using dried blood spots and plasma.

Metabolic remodeling in glioblastoma: a longitudinal multi-omics study.

Monitoring tumor evolution and predicting survival using non-invasive liquid biopsy is an unmet need for glioblastoma patients. The era of proteomics and metabolomics blood analyzes, may help in this context. A case-control study was conducted.

New insights and potential biomarkers for intraventricular hemorrhage in extremely premature infant, case-control study.

Background: Despite advancements in neonatal care, germinal matrix-intraventricular hemorrhage impacts 20% of very preterm infants, exacerbating their neurological prognosis. Understanding its complex, multifactorial pathophysiology and rapid onset remains challenging. This study aims to link specific cord blood biomolecules at birth with post-natal germinal matrix-intraventricular hemorrhage onset.
