Blended diets for gastrostomy fed children: A scoping review

Objective: The objective of the review was to identify what is known about the use of blended diets with gastrostomy fed children and young people and to identify gaps in the literature on this topic in order to inform future research and policy. Method: A scoping review methodology was used; searching online databases PUBMED, PsychINFO, CINAHL, SCOPUS and AMED, EMBASE for articles that addressed issues pertaining to blended diets. The review identified a broad range of literature regardless of study design and described and evaluated the quality, range and nature of research activity related to the use of blenderised diets. Results: Forty-three studies were included in the review. The studies focused on nutrition, equipment, views of carers and patients and views of professionals. Several studies described the lack of evidence regarding pros and cons of blended diets and highlighted the need for further research into the field. Conclusions: There were gaps in the evidence base regarding the impact of blended diets on health and well-being of the children who are given them and upon the carers who feed them. The nutritional impact of blended diets is not fully understood, and the knowledge and views of professionals involved in the care of those receiving blended diets varies

Creating and improving multi-threaded Geant4

We document the methods used to create the multi-threaded prototype Geant4MT from a sequential version of Geant4. We cover the Source-to-Source transformations applied, and discuss the process of verifying the correctness of the Geant4MT toolkit and applications based on it. Tools to ensure that the results of a transformed multi-threaded application are exactly equal to the original sequential version are under development. Stand-alone or simple applications can be adapted within 1-2 working days. Geant4MT is shown to scale linearly on an 80-core computer. In the special case of a single worker thread on one core, 30% overhead has been observed. We explain the reasons for this and the improvements introduced to reduce this overhead
