AI Article Synopsis

  • - Invasive fungal infections (IFIs) are frequent and serious complications for patients who have undergone hematopoietic stem cell transplantation (HSCT), leading to severe health issues and high mortality rates.
  • - Recent advancements in non-culture diagnostic techniques, such as biosensors and AI-assisted methods, have improved the detection of IFIs, which helps in making better treatment decisions and enhances survival rates for post-HSCT leukemia patients.
  • - The review highlights two common IFIs in HSCT patients, introduces new detection technologies, and discusses the potential of a specific method called CCP-FRET for identifying IFIs, aiming to guide the choice of diagnostic approaches in labs.

Article Abstract

Invasive fungal infections (IFIs) are common and life-threatening complications in post-hematopoietic stem cell transplantation (post-HSCT) recipients, Severe IFIs can lead to systemic infection and organ damage, which results in high mortality in HSCT recipients. With the development of the field of fungal infection diagnosis, more and more advanced non-culture diagnostic tools have been developed, such as glip biosensors, metagenomic next-generation sequencing, Magnetic Nanoparticles and Identified Using SERS via AgNPs , and artificial intelligence-assisted diagnosis. The advanced diagnostic approaches contribute to the success of HSCT and improve the overall survival of post-HSCT leukemia patients by supporting therapeutical decisions. This review provides an overview of the characteristics of two high-incidence IFIs in post-HSCT recipients and discusses some of the recently developed IFI detection technologies. Additionally, it explores the potential application of cationic conjugated polymer fluorescence resonance energy transfer (CCP-FRET) technology for IFI detection. The aim is to offer insights into selecting appropriate IFI detection methods and gaining an understanding of novel fungal diagnostic approaches in laboratory settings.

Hemato-oncologic children form a heterogeneous group with a wide spectrum of ages, malignancy types, and immunosuppression grades during the different phases of their treatment. Immunosuppression is caused by multiple factors, including the malignancy itself, bone marrow suppression secondary to therapy, and wide use of steroids and antibiotics, among others. At the same time, the risk of infections in these patients remains high because of prolonged hospitalizations or the need for long-timing implanted devices between other features.

Estimating annulus sealing properties using the flexural wave spectrum in pitch-catch well-logging.

Ultrasonics

February 2025

Department of Informatics, University of Oslo, P.O. Box 1080, Oslo, NO-0316, Norway. Electronic address:

Article Synopsis
  • Safe oil and gas well operations depend on properly sealing the annulus casing, which can be inspected using pitch-catch ultrasound logging measurements.
  • This paper introduces a data processing method that distinguishes between solid (like cement) and fluid (like mud) in the annulus by analyzing the spectral signature of casing flexural waves.
  • A binary algorithm is developed to detect the presence of a notch dip in the data, which indicates material type, and the study validates the algorithm's performance using both simulated and field data.

Article Synopsis
  • * A study conducted from March to December 2023 in Honduras assessed the capabilities for diagnosing and treating IFIs, revealing a lack of consistent use of available diagnostic methods and inadequate antifungal options in health care facilities.
  • * The findings indicated that while basic antifungal medications like fluconazole are available, more potent options are scarce, and advanced diagnostic techniques for fungal infections are largely absent, creating major barriers to effective IFI management.

Article Synopsis
  • A rapid and universal LC-MS/MS method was established to measure the levels of five triazole antifungal drugs in human plasma, targeting drugs such as voriconazole and fluconazole.
  • The method involved a triple quadrupole mass spectrometer and used gradient elution on a specific column, with accurate calibration ranges and strong correlation for all analyzed substances.
  • The results demonstrate that this method is efficient and reliable, having been successfully applied to plasma samples from 66 patients, aiding in clinical treatment of fungal infections.
