Background/aims: Cholecystokinin (CCK) administration has been shown to reduce lower esophageal sphincter (LES) pressure in normal subjects in manometric studies. Functional luminal imaging probe (FLIP) panometry offers a method to assess esophageal motility in response to sustained distension though mechanisms related to this response remain unexplored. The aim of this study is to evaluate the effect of CCK-8 on the esophageal response to distension in asymptomatic volunteers using FLIP.

- - The study examines how multifocal glasses, particularly those with progressive lenses, may increase the risk of falls in elderly individuals by evaluating the prismatic displacement effects of these lenses on their visual perception and reaction time.
- - Researchers tested 31 healthy participants aged 75 and older to measure their reaction times while wearing progressive lenses versus single vision glasses, finding quicker reactions with progressives in certain positions but no difference in accuracy.
- - The findings suggest that older adults can adapt to the visual distortions caused by progressive lenses, but significant changes in prescription or swapping glasses frequently could lead to an increased risk of falling.
