Multi-angle acquisition and 3D composite reconstruction for organ-targeted PET using planar detectors.
Med Phys
December 2024
Department of Physics, Lakehead University, Thunder Bay, Ontario, Canada.
Background: This study investigates a multi-angle acquisition method aimed at improving image quality in organ-targeted PET detectors with planar detector heads. Organ-targeted PET technologies have emerged to address limitations of conventional whole-body PET/CT systems, such as restricted axial field-of-view (AFOV), limited spatial resolution, and high radiation exposure associated with PET procedures. The AFOV in organ-targeted PET can be adjusted to the organ of interest, minimizing unwanted signals from other parts of the body, thus improving signal collection efficiency and reducing the dose of administered radiotracer.

PLoS One
December 2024
Section of Rehabilitation in Orthopaedics, Clinical Rehabilitation Institute, Faculty of Motor Rehabilitation, University of Physical Education, Krakow, Poland.
Background: Postural stability is essential for functional independence in the pregnant population. The contradictions between existing studies and the lack of consistent characteristics in the strategies used by pregnant women for postural control demonstrate the need for further investigation.
Objectives: The aim was to review the available literature on postural strategies throughout pregnancy in both static and dynamic conditions and to provide an assessment of the quality of these studies in terms of methodological issues to identify the reasons for the inconsistencies in findings between research centers.
Improving Time to Completion of Medical Student Clerkship Evaluations.
Hosp Pediatr
December 2024
Department of Pediatrics, Division of Hospital Medicine, The University of Alabama at Birmingham Heersink School of Medicine, Birmingham, Alabama.
Background And Objectives: Medical student clinical clerkship evaluations provide feedback for growth and contribute to the clerkship grade and the student's residency application. Their importance is expected to increase even more with the recent change of the US Medical Licensing Examination Step 1 to a pass/fail designation. Timely completion of medical student clerkship evaluations is a problem.

MAGMA
December 2024
Department of Radiology and Medical Informatics, Faculty of Medicine, University of Geneva, Geneva, Switzerland.
Objectives: Phosphorus-31 magnetic resonance spectroscopic imaging (P-MRSI) is a non-invasive tool for assessing cellular high-energy metabolism in-vivo. However, its acquisition suffers from a low sensitivity, which necessitates large voxel sizes or multiple averages to achieve an acceptable signal-to-noise ratio (SNR), resulting in long scan times.
Materials And Methods: To overcome these limitations, we propose an acquisition and reconstruction scheme for FID-MRSI sequences.
Jazz dancing for improving cardiorespiratory fitness, body composition, muscle strength, and sleep quality in postmenopausal women: a randomized clinical trial with 6- and 12-month follow-ups.
Menopause
January 2025
From the Department of Physiotherapy, Santa Catarina State University, Florianópolis, Brazil.
Objective: The aim of the study was to analyze the effects of 16 weeks of Jazz Dance training compared to a control group in postmenopausal women, postintervention, and at the 6- and 12-month follow-ups, on cardiorespiratory fitness, body composition, muscle strength, and sleep quality.
Methods: Two-arm randomized clinical trial with a total of 47 women (jazz dance intervention group [JDIG] [n = 23] and control group (CG) [n = 24]) with a mean age of 53.41 ± 2.
