NCT07300670
The goal of this clinical trial is to investigate the effects of the blood pressure-lowering drug losartan on the blood levels and urinary excretion of the antibiotic cephalexin during simultaneous and staggered ingestion in healthy volunteers. The main questions it aims to answer are: 1. Does losartan affect cephalexin levels and excretion when ingested at the same time? 2. Does a three-hour interval between ingestion of losartan and cephalexin eliminate a possible effect? Researchers will compare the effects of losartan ingested at the same time, losartan ingested three hours prior, and no losartan ingested on oral cephalexin in each participant to see whether an interaction exists and could be avoided. Participants will visit the research laboratory on three days during which they will ingest single doses of losartan at the same time with, three hours prior to, and not at all prior to ingesting single doses of cephalexin.

Children with cerebral palsy (CP) present a variety of motor impairments and activity limitations. Plastic ankle-foot orthoses (pl-AFO) are frequently prescribed to improve their gait. However, their use limit forward propulsion generation, which explains why children tend to remove their pl-AFO during recreational activities,including running and jumping. While the benefits of physical activity are proven for these children, there is no data about pl-AFO impact across a range of locomotor activities. Biomechanically optimized dynamic carbon fiber AFOs (c-AFO) are now available and may improve propulsion features in comparison with usual pl-AFOs. The investigators aim to compare the AFO-specific effects (pl-AFO vs c-AFO) on propulsion (during walking, running and jumping), to explore the consequences on social participation, as well as to evaluate the effect on the hemiparetic CP child's perception and adherence of wearing each AFO. In this prospective, multicenter, randomized controlled trial with a crossover design, 38 hemiparetic CP children from 8 to 15 years old will be evaluated with their usual pl-AFO and with a c-AFO. The pragmatic clinical approach of this study is expected to provide data to guide and optimize AFO prescription and use, while enhancing understanding of these devices and their adaptation to the actual physical activity of CP children.
