Thin-section, high-resolution (1.0/1.5 mm thick slices), low-dose chest CT scans were performed in 55 infants and children. The studies were carried out with 1- and 2-s scan (data acquisition) times using a high-resolution (bone) algorithm. Although there was some motion artifact, the studies provided valuable information for evaluating diffuse parenchymal lung disease. The thin slices provided finer detail and more diagnostic information than images representing thicker sections. Most studies were performed using between 40 and 80 mAs. It is estimated that the patients' radiation exposure was 20% that of conventional high-resolution CT (HRCT) and 57% that of routine chest CT. Diagnostic HRCT scans can be obtained in infants and young children without the need for suspended respiration or specialized ultrafast CT scanners.

Clinical Outcomes with High- versus Low-Dose Tranexamic Acid Infusion in Patients Undergoing Cardiac Surgery: A Systematic Review and Meta-Analysis.
Thorac Cardiovasc Surg

Department of Medicine, MedStar Health, Baltimore, Maryland, United States.
Objectives: Antifibrinolytics, such as tranexamic acid (TXA), are widely used in cardiac surgery to reduce bleeding risks; however, the optimal dosage for TXA infusion remains a subject of debate. Hence, this study aims to evaluate the safety and efficacy of high-dose compared with low-dose TXA infusion in cardiac surgery patients.
Methods: PubMed, SCOPUS, and Cochrane Central Register of Controlled Trials (CENTRAL) were searched until June 10, 2023, for studies assessing efficacy outcomes (e.

Background: Improving the resuscitation and teamwork skills of residents is key to better outcomes of in-hospital cardiac arrest events. This study aims to explore the effects of regular low-dose simulation combined with a booster workshop on the progression and retention of resuscitation skills and teamwork among residents.
Methods: This comparative study took place at a teaching hospital in Northern Taiwan from August 2019 to June 2021.
A comparative analysis of image harmonization techniques in mitigating differences in CT acquisition and reconstruction.

Radiological Sciences, University of California Los Angeles, 924 Westwood Blvd, Los Angeles, California, 90095, UNITED STATES.
Objective: The study aims to systematically characterize the effect of CT parameter variations on images and lung radiomic and deep features, and to evaluate the ability of different image harmonization methods to mitigate the observed variations.
Approach: A retrospective in-house sinogram dataset of 100 low-dose chest CT scans was reconstructed by varying radiation dose (100%, 25%, 10%) and reconstruction kernels (smooth, medium, sharp). A set of image processing, convolutional neural network (CNNs), and generative adversarial network-based (GANs) methods were trained to harmonize all image conditions to a reference condition (100% dose, medium kernel).
The MyLungHealth study protocol: a pragmatic patient-randomised controlled trial to evaluate a patient-centred, electronic health record-integrated intervention to enhance lung cancer screening in primary care.

Department of Biomedical Informatics, University of Utah, Salt Lake City, Utah, USA.
Introduction: Early lung cancer screening (LCS) through low-dose CT (LDCT) is crucial but underused due to various barriers, including incomplete or inaccurate patient smoking data in the electronic health record and limited time for shared decision-making. The objective of this trial is to investigate a patient-centred intervention, MyLungHealth, delivered through the patient portal. The intervention is designed to improve LCS rates through increased identification of eligible patients and informed decision-making.

Background: Delirium is a common and serious syndrome of acute brain dysfunction associated with negative outcomes. Melatonin may have a role in delirium prevention for critically ill adults based on data from non-critically ill patient populations. Our objective was to assess the feasibility of a multi-centre, randomized, placebo-controlled trial testing the hypothesis that low-dose melatonin prevents delirium in critically ill adults.
