A comparison of language control while switching within versus between languages in younger and older adults.

Word retrieval during language production slows down with age. However, bilinguals also require language control to manage language competition, in particular when switching languages to cues. The current study examined how this bilingual language control differs between younger and older adults.

Current Research on Vitamin D Supplementation against Sarcopenia: A Review of Clinical Trials.

Vitamin D plays an important role in skeletal muscle function and metabolism. The aim of this review was A) to discuss the clinical evidence of vitamin D supplementation either alone or combined with other strategies in the prevention of sarcopenia in non-sarcopenic individuals and B) to critically discuss the clinical evidence on the effect of vitamin D combined with other strategies on muscle strength, mass and function in sarcopenic individuals without vitamin D deficiency. Sparse clinical data on non-sarcopenic individuals indicate that vitamin D alone has a subtle beneficial effect on knee extensor strength at doses 880-1600 IU/day without improving handgrip strength or muscle mass.

Clinical Imaging Research: Higher Evidence, Global Collaboration, Improved Reporting, and Data Sharing Are the Grand Challenges.

The four grand challenges of imaging research—increasing evidence levels, enhancing global collaboration, improving research reporting quality, and sharing trial data—can be addressed, utilizing the tail wind of digital transformation, by consolidating actions of all stakeholders, with the ultimate goal of evidence-based, reproducible, generalizable, and broadly accepted results that will improve the quality and consistency of patient care.

Impact and perceived value of journal reporting guidelines among Radiology authors and reviewers.
