Introduction: Predicting purulent arthritis with a single marker may result in low sensitivity and specificity. We investigated the diagnostic value of serum markers and joint fluid C-reactive protein (CRP) in purulent arthritis.
Methodology: A total of 183 patients with acute joint infection, who were treated at our hospital between April 2019 and September 2022, were retrospectively analyzed via convenient sampling.
Diagnostic value of nanopore sequencing of cerebrospinal fluid samples in tuberculous meningitis.
Diagn Microbiol Infect Dis
February 2025
Article Synopsis
- - The study aimed to evaluate how effective nanopore sequencing technology is for diagnosing tuberculous meningitis (TBM) using cerebrospinal fluid samples from patients.
- - Compared to traditional methods like acid-fast staining and culture, nanopore sequencing had a sensitivity of 43.30% and an area under the ROC curve of 0.661, indicating better performance overall.
- - When nanopore sequencing was used alongside imaging techniques, it achieved the best diagnostic results with increased sensitivity, specificity, and predictive values, showing its potential as a reliable tool for TBM diagnosis.
Objective: To evaluate whether the intense simplified strategy, which comprises short term intensive insulin therapy (SIIT) followed by subsequent oral antihyperglycaemic regimens, could improve long term glycaemic outcomes in patients with newly diagnosed type 2 diabetes mellitus and severe hyperglycaemia.
Design: Multicentre, open label, randomised trial.
Setting: 15 hospitals in China between December 2017 and December 2020.
4-Hydroxybenzoate (4HBA) is an important chemical compound used for synthesis of liquid crystal. Production of 4HBA from renewable resources is an effective mean to solve problems such as environmental pollution and petroleum shortage. This review briefly introduces the chemical synthesis of 4HBA from oil compounds, and mainly describes the progress in 4HBA biosynthesis from renewable resources by plants and microorganisms.
