Systematic review on epidemiology of in bloodstream infection of patients undergoing hematopoietic stem cell transplantation.

Introduction: We aimed to conduct a systematic review of the epidemiology of in bloodstream infections (BSI) of hematopoietic stem cell transplantation patients.

Methods: For a comprehensive search of studies that reported the prevalence of and antibiotic resistance in bloodstream infections from 2000 to January 1, 2024, databases such as PubMed, EMBASE, Google Scholar, Scopus, and Web of Science were searched. The main keywords used were: , epidemiology, bloodstream infection, microbial resistance, antibiotic resistance, hematopoietic malignancy, hematopoietic stem cell transplantation.

Breathing-induced Errors in Quantification and Description of Dominant Intra-Prostatic Lesions (Dils) in PET Images: A Simulation Study by Means of The 4D NCAT Phantom.

Background: Respiratory movement and the motion range of the diaphragm can affect the quality and quantity of prostate images.

Objective: This study aimed to investigate the magnitude of respiratory-induced errors to determine Dominant Intra- prostatic Lesions (DILs) in positron emission tomography (PET) images.

Material And Methods: In this simulation study, we employed the 4D NURBS-based cardiac-torso (4D-NCAT) phantom with a realistic breathing model to simulate the respiratory cycles of a patient to assess the displacement, volume, maximum standardized uptake value (SUV), mean standardized uptake value (SUV), signal to noise ratio (SNR), and the contrast of DILs in frames within the respiratory cycle.

Evaluation of Dose-Painting in the Dominant Intraprostatic Lesions by Radiobiological Parameters using Ga- PSMA PET/CT.

Background: Patients diagnosed with dominant intraprostatic lesions (DIL) may need radiation doses over than 80 Gy. Dose-painting by contours (DPC) is a useful technique which helps the patients. Dose-painting approach need to be evaluated.
