Journal Article
Wilkinson-Smith, V., Menys, A., Bradley, C., Corsetti, M., Marciani, L., Atkinson, D., Coupland, C., Taylor, S., Gowland, P., Spiller, R., & Hoad, C. (2020). The MRI colonic function test: Reproducibility of the Macrogol stimulus challenge. Neurogastroenterology and Motility, 32(11), Article e13942. https://doi.org/10.1111/nmo.13942

Background

Magnetic resonance imaging (MRI) of the colonic response to a macrogol challenge drink can be used to assess the mechanisms underlying severe constipation. We measured the intra-subject reproducibility of MRI measures of colonic funct... Read More about The MRI colonic function test: Reproducibility of the Macrogol stimulus challenge.

American Journal of Psychiatry, 177(9), 844-854. https://doi.org/10.1176/appi.ajp.2020.19020183

Objective:

The dual-pathway model has been proposed to explain the heterogeneity in symptoms of attention deficit hyperactivity disorder (ADHD) by two independent psychological pathways based on distinct brain circuits. The authors sought to test... Read More about Neural correlates of the dual pathway model for attention-deficit/hyperactivity disorder in adolescents.

Neurobehavioural characterisation and stratification of reinforcement-related behaviour. Nature Human Behaviour, 4, 544–558. https://doi.org/10.1038/s41562-020-0846-5

Reinforcement-related cognitive processes, such as reward processing, inhibitory control and social-emotional regulation are critical components of externalising and internalising behaviours. It is unclear to what extent the deficit in each of these... Read More about Neurobehavioural characterisation and stratification of reinforcement-related behaviour.

Journal Article

Identification of neurobehavioural symptom groups based on shared brain mechanisms. Nature Human Behaviour, 3, 1306–1318. https://doi.org/10.1038/s41562-019-0738-8

Most psychopathological disorders develop in adolescence. The biological basis for this development is poorly understood. To enhance diagnostic characterization and develop improved targeted interventions, it is critical to identify behavioural sympt...

Journal Article
Khalaf, A., Hoad, C. L., Menys, A., Nowak, A., Radford, S., Taylor, S. A., Latief, K., Lingaya, M., Falcone, Y., Singh, G., Spiller, R. C., Gowland, P. A., Marciani, L., & Moran, G. W. (2020). Gastrointestinal peptides and small bowel hypomotility are possible causes for fasting and postprandial symptoms in active Crohn’s disease. American Journal of Clinical Nutrition, 111(1), 131–140. https://doi.org/10.1093/ajcn/nqz240

Background
Crohn's disease (CD) patients suffer postprandial aversive symptoms, which can lead to anorexia and malnutrition. Changes in the regulation of gut hormones and gut dysmotility are believed to play a role.

Objectives
This study aimed t... Read More about Gastrointestinal peptides and small bowel hypomotility are possible causes for fasting and postprandial symptoms in active Crohn’s disease.

British Journal of Nutrition, https://doi.org/10.1017/S0007114519001880

Whole grain cereal breakfast consumption has been associated with beneficial effects on glucose and insulin metabolism as well as satiety. Pearl millet is a popular ancient grain variety that can be grown in hot, dry regions. However, little is known...
