Frailty and Health Outcomes in People 65 Years or Older Living With Dementia: A Systematic Review of the Literature

Journal of the American Geriatrics Society, Volume 74, Issue 3, Page 854-867, March 2026.
ABSTRACT Introduction Although frailty is considered a potentially modifiable risk factor for dementia, its influence on health outcomes in individuals with established dementia remains unclear. This study aims to systematize the current evidence to understand the impact of frailty on the development of adverse outcomes in older adults with dementia ...

Pinopsin Regulates Melatonin Production and Daily Locomotor Activity: Functional Insights From Gene‐Edited Xenopus Tadpoles

Journal of Pineal Research, Volume 78, Issue 2, March 2026.
ABSTRACT Circadian rhythm alignment depends on environmental light detection via opsins. Pinopsin, originally identified in the pineal organ of birds and later in amphibian pineal complex and eyes, may play a role in this process, though its function has not been genetically tested.

Radiologic Insights: Diagnosing Lumbosacral Transitional Vertebrae. Systematic Review of the Literature

Pain Practice, Volume 26, Issue 3, March 2026.
ABSTRACT Introduction The lumbosacral transitional vertebra (LSTV) has been studied since 1876, with Castellvi developing a classification in 1984 based on its anatomy and laterality. It often goes unnoticed, or its diagnosis is limited to a lumbar spine X‐ray for confirmation. This has led to LSTV being underdiagnosed or even ignored.
