Objectives: Platform trials were used successfully in adult populations during the COVID-19 pandemic. By testing multiple treatments within a single trial, platform trials can help identify the most effective treatments (and any interactions between treatments) for patients more quickly and with less burden for patients and their families. The aim of this qualitative research was to inform the design of the first adaptive platform trial for paediatric intensive care in the UK with young people, parents/carers and paediatric intensive care unit (PICU) staff.

Grasses are fundamental to human survival, providing a large percentage of our calories, fuel, and fodder for livestock, and an enormous global carbon sink. A particularly important part of the grass plant is the grain-producing inflorescence that develops in response to both internal and external signals that converge at the shoot tip to influence meristem behavior. Abiotic signals that trigger reproductive development vary across the grass family, mostly due to the unique ecological and phylogenetic histories of each clade.

Purpose: This study evaluates the initial efficacy of Chaining SPeech Lessons in Intensive Ten-minute Sessions (SPLITS), an alternative service delivery model for the Speech Motor Chaining treatment approach. We hypothesized that Chaining SPLITS would result in improvements in /ɹ/ accuracy on syllables and untrained words when compared to a no-treatment condition.

Method: Within a randomized controlled trial, thirteen 7-9-year-old children with difficulty producing /ɹ/ were randomized to receive treatment either immediately or after an 8-week delay.

Ocean ecosystems have been subjected to anthropogenic influences for centuries, but the scale of past ecosystem changes is often unknown. For centuries, the European flat oyster (Ostrea edulis), an ecosystem engineer providing biogenic reef habitats, was a culturally and economically significant source of food and trade. These reef habitats are now functionally extinct, and almost no memory of where or at what scales this ecosystem once existed, or its past form, remains.
