Reporting of Participant Demographics in Clinical Trials Published in General Radiology Journals.

Objectives: The reporting of research participant demographics provides insights into study generalizability. Our study aimed to determine the frequency at which participant age, sex/gender, race/ethnicity, and socioeconomic status (SES) are reported and used for subgroup analyses in radiology randomized controlled trials (RCTs) and their secondary analyses; as well as the study characteristics associated with, and the classification systems used for demographics reporting.

Methods: RCTs and their secondary analyses published in 8 leading radiology journals between 2013 and 2021 were included.

Left fourth and sixth costovertebral dislocation abutting the aorta.

While rib fractures are common in blunt thoracic trauma, dislocations of the costovertebral joints (CVJs) are extremely rare and typically involve the first, eleventh, or twelfth rib. We report a rare case of dislocation of the left fourth and sixth CVJs in a 36-year-old man who was run over by a car. The rib heads were displaced anteriorly, abutting the aorta.

[THE EFFECTIVENESS OF TREATMENT IN CHILDREN WITH RIGID FLATFEET AND DYSFUNCTION OF THE POSTERIOR TIBIAL TENDON].

The rigid form of longitudinal flatfeet is one of the most common deformities of the foot in children. Dysfunction of the posterior tibial tendon is one of the causes of rigid foot formation with the development of pain syndrome, degenerative-dystrophic changes in the tarsal bones and joints. In most of these cases, conservative treatment is ineffective, prompting the use of surgical methods of foot correction - subtalar arthroereisis.

Second-order Raman spectra of a LiNbO:Tb crystal.

Additional bands have been discovered for the first time in the Raman spectra of terbium doped lithium niobate crystals. The bands have been determined in the high-frequency region and have been attributed to the overtone states of the second order of polar fundamental modes of the crystal lattice. It has been established that Raman spectrum of terbium doped lithium niobate contains bands with frequencies exceeding the overtones of the highest-frequency fundamental polar modes of A(Z) and E(X, Y) symmetry types.

Stimulated boson-peak light scattering in an aqueous suspension of spherical nanoparticles of amorphous SiO of similar sizes.

A forward-directed high-efficiency stimulated inelastic light scattering was detected in an aqueous suspension of spherical nanoparticles (nanoballs) of amorphous SiO2 of similar sizes (0.25 μm) with a concentration of 1013 cm-3. In the stimulated scattering spectrum, there was an intense forward directed Stokes component with a frequency shift of 0.
