GeneXpert MTB/RIF Ultra in Pediatric Tuberculosis: How Disease Characteristics Modify Test Performances.

Introduction: The diagnosis of pediatric tuberculosis (TB) is challenging, due to the lower sensitivity of microbiological tests, such as culture and microscopy, compared to their performance in adult cases. Guidelines have introduced molecular tests, including GeneXpert MTB/ RIF and GeneXpert MTB/RIF Ultra. These tests use a real-time polymerase chain reaction method and provide information on M.

Lipidomics of coconut, almond and soybean milks - Detailed analysis of polar lipids and comparison with bovine milk.

In this work, the lipidomic analysis on polar components of almond, coconut, and soy beverages was performed by liquid chromatography quadrupole time-of-flight mass spectrometry. A comparison with bovine milk was also performed. A total of 30 subclasses of polar lipids, belonging mainly to glycerophospholipids and sphingolipids, and a total of 572 molecular species were identified.

Parallel single-cell metabolic analysis and extracellular vesicle profiling reveal vulnerabilities with prognostic significance in acute myeloid leukemia.

Acute myeloid leukemia (AML) is an aggressive disease with a high relapse rate. In this study, we map the metabolic profile of CD34(CD38) AML cells and the extracellular vesicle signatures in circulation from AML patients at diagnosis. CD34 AML cells display high antioxidant glutathione levels and enhanced mitochondrial functionality, both associated with poor clinical outcomes.

Water-assisted colonoscopy in inflammatory bowel diseases: From technical implications to diagnostic and therapeutic potentials.

Water-assisted colonoscopy (WAC) application in inflammatory bowel diseases (IBD) endoscopy offers significant technical opportunities. Traditional gas-aided insufflation colonoscopy increases patient discomfort, presenting challenges in the frequent and detailed mucosal assessments required for IBD endoscopy. WAC techniques, including water immersion and exchange, provide superior patient comfort and enhanced endoscopic visualisation.

Long-Term Effectiveness and Safety of Ustekinumab in Crohn's Disease: Results from a Large Real-Life Cohort Study.

Ustekinumab (UST) is an interleukin-12/interleukin-23 receptor antagonist approved for the treatment of Crohn's disease (CD). Only limited real-life data on the long-term outcomes of CD patients treated with UST are available. This study assessed UST's long-term effectiveness and safety in a large population-based cohort of moderate to severe CD patients.
