Evaluation of a Deep Learning Denoising Algorithm for Dose Reduction in Whole-Body Photon-Counting CT Imaging: A Cadaveric Study.
Acad Radiol
January 2025
Department of Radiology, University Hospital Tuebingen, Hoppe-Seyler-Str. 3, 72076 Tuebingen, Germany (R.D., J.M.B., B.S., J.M., S.G., P.K., S.W., J.H., K.N., S.A., A.B.).
Rationale And Objectives: Photon Counting CT (PCCT) offers advanced imaging capabilities with potential for substantial radiation dose reduction; however, achieving this without compromising image quality remains a challenge due to increased noise at lower doses. This study aims to evaluate the effectiveness of a deep learning (DL)-based denoising algorithm in maintaining diagnostic image quality in whole-body PCCT imaging at reduced radiation levels, using real intraindividual cadaveric scans.
Materials And Methods: Twenty-four cadaveric human bodies underwent whole-body CT scans on a PCCT scanner (NAEOTOM Alpha, Siemens Healthineers) at four different dose levels (100%, 50%, 25%, and 10% mAs).
The effect of cognitive task and gait speed on gait spatiotemporal parameters in athletes with anterior cruciate ligament reconstruction: Cross-sectional study.
Knee
January 2025
Musculoskeletal Research Center, Department of Physical Therapy, School of Rehabilitation Sciences, Isfahan University of Medical Sciences, Isfahan, Iran.
Background: Restoring pre-injury normal gait following Anterior Cruciate Ligament Reconstruction (ACLR) is a critical challenge. The purpose of this study was to compare spatiotemporal parameters in athletes following ACL reconstruction with healthy athletes when cognitive load and speed were manipulated.
Methods: Twenty male soccer players with an ACLR history and 20 healthy matched individuals completed walking tasks under four conditions: with and without a cognitive load (auditory Stroop task), and at preferred speed as well as high speed (20% higher than the individual's preferred speed).
Reconstructive techniques for chest and breast deformities in Poland syndrome: An up-to-date systematic review.
J Plast Reconstr Aesthet Surg
December 2024
Department of Surgery, Division of Plastic and Reconstructive Surgery, Stanford University, Stanford, CA, United States.
Background: Poland syndrome (PS) is a congenital abnormality defined as aplasia or hypoplasia of the unilateral pectoralis muscle and breast tissue that may be accompanied by limb or thoracic deformities. Reconstruction of deformities associated with PS is challenging owing to the spectrum of differences. We aimed to evaluate the trends in surgical management of chest and breast anatomical anomalies associated with PS.

January 2025
Microbiology Unit, Clinical Pathology Department, Piacenza General Hospital, Piacenza, Italy; Medicine and Surgery Department, University of Parma, Parma, Italy.
Objectives: Infections by Carbapenem-Resistant Enterobacterales in hospitals represent a severe threat but little is known on outbreaks in rehabilitation wards caused by Klebsiella pneumoniae producing Klebsiella pneumoniae Carbapenemase (KPC-Kp). We report an outbreak by KPC-Kp, in a Neurorehabilitation Unit in Italy, analysed through Whole-Genome Sequencing (WGS) for transmission routes reconstruction to improve management of KPC-Kp infections in rehabilitation units.
Methods: We investigated cases and KPC-Kp isolates collected from February to October 2022 from hospital surveillance.
Minimally Invasive Glass-Ceramic Restorations: Clinical and Patient-Reported Outcomes in Full-Mouth Rehabilitations.
J Dent
January 2025
Clinic of Reconstructive Dentistry, Center for Dental Medicine, University of Zurich, Plattenstrasse 11, CH-8032, Zurich, Switzerland.
Objectives: To evaluate clinical outcomes (restoration survival, technical and biological complications), and patient-reported outcome measures (PROMs) of full mouth rehabilitation with minimally invasive glass-ceramic restorations after up to 12 years of clinical service.
Materials And Methods: Twenty individuals (12 females, 8 males) received full-mouth rehabilitation with minimally invasive tooth-supported glass-ceramic restorations during the years 2009 - 2017 and agreed to participate in a follow-up visit. Full dental and periodontal examinations were completed, and the restorations were evaluated according to United States Public Health Service (USPHS) criteria.
