Children with congenital heart disease are at high risk for malnutrition. Standardisation of feeding protocols has shown promise in decreasing some of this risk. With little standardisation between institutions’ feeding protocols and no understanding of protocol adherence, it is important to analyse the efficacy of individual aspects of the protocols.
Adherence to and deviation from a feeding protocol in high-risk congenital heart disease patients between December 2015 and March 2017 were analysed. Associations between adherence to and deviation from the protocol and clinical outcomes were also assessed. The primary outcome was change in weight-for-age z score between time intervals.
Increased adherence to and decreased deviation from individual instructions of a feeding protocol improves patients change in weight-for-age z score between birth and hospital discharge (p = 0.031). Secondary outcomes such as markers of clinical severity and nutritional delivery were not statistically different between groups with high or low adherence or deviation rates.
High-risk feeding protocol adherence and fewer deviations are associated with weight gain independent of their influence on nutritional delivery and caloric intake. Future studies assessing the efficacy of feeding protocols should include the measures of adherence and deviations that are not merely limited to caloric delivery and illness severity.

Given the contribution Andrew Ayton has made to the study of late medieval military history we hope he is not surprised by the production of a Festschrift in his honour. All the editors of this volume were supervised by Andrew for their doctoral studies, and all no doubt thrashed out the general outlines to their theses in one of the infamous ‘Ayton’ meetings that regularly ran into the late evening. Andrew's enthusiasm for his subject was infectious and it is to his credit that many of his former students have gone on to publish contributions on late medieval military and naval history. The papers featured in the present volume highlight the important international impact Andrew's work has had on his students and academic colleagues.
Andrew, a native of Dorset, is in his own words ‘a country dweller at heart’ but has spent much of his working life in the big city. He studied as an undergraduate at the University of Hull in the early 1980s, during which time he undertook several modules taught by Professor John Palmer. John's module on the Hundred Years’ War in particular seems to have kindled Andrew's interest in medieval military history and military communities; it certainly began a fruitful association between two like-minded scholars which was to span some three decades until John's retirement in 2002. Andrew often visited John's home to discuss their latest research and he will be pleased to know he is remembered with some affection by John's children.
After graduating, Andrew spent a brief spell in a ‘real’ job, before returning to Hull to study for his Ph.D. under John Palmer – ‘The Warhorse and Military Service under Edward III’ – and from 1985 to 1987 Andrew was employed, alongside Virginia Davis, on John's Domesday Project. This was a role for which Andrew was particularly well equipped. He had taken John Palmer's special subject on the Domesday Book as an undergraduate, which had provided him with the essential background plus the basic computing skills – in particular related to databases – needed for the research: rare qualifications in the mid-1980s. This period, of course, included the 900th anniversary of Domesday Book, which for Andrew and Virginia entailed a frenetic year, giving lectures and demonstrations around the UK while trying to keep to a research schedule and do some work on their own account.
Children with hypoplastic left heart syndrome are at a risk for neurodevelopmental delays. Current guidelines recommend systematic evaluation and management of neurodevelopmental outcomes with referral for early intervention services. The Single Ventricle Reconstruction Trial represents the largest cohort of children with hypoplastic left heart syndrome ever assembled. Data on life events and resource utilisation have been collected annually. We sought to determine the type and prevalence of early intervention services used from age 1 to 4 years and factors associated with utilisation of services.
Data from 14-month neurodevelopmental assessment and annual medical history forms were used. We assessed the impact of social risk and geographic differences. Fisher exact tests and logistic regression were used to evaluate associations.
Annual medical history forms were available for 302 of 314 children. Greater than half of the children (52–69%) were not receiving services at any age assessed, whereas 20–32% were receiving two or more therapies each year. Utilisation was significantly lower in year 4 (31%) compared with years 1–3 (with a range from 40 to 48%) (p<0.001). Social risk factors were not associated with the use of services at any age but there were significant geographic differences. Significant delay was reported by parents in 18–43% of children at ages 3 and 4.
Despite significant neurodevelopmental delays, early intervention service utilisation was low in this cohort. As survival has improved for children with hypoplastic left heart syndrome, attention must shift to strategies to optimise developmental outcomes, including enrolment in early intervention when merited.
The star R Corona Borealis (R CrB) shows forbidden lines of [O II], [N II], and [S II] during the deep minimum when the star is fainter by about 8 to 9 magnitudes from normal brightness, suggesting the presence of nebular material around it. We present low and high spectral resolution observations of these lines during the ongoing deep minimum of R CrB, which started in July 2007. These emission lines show double peaks with a separation of about 170 km/s. The line ratios of [S II] and [O II] suggest an electron density of about 100 cm−3. We discuss the physical conditions and possible origins of this low density gas. These forbidden lines have also been seen in other R Coronae Borealis stars during their deep light minima and this is a general characteristic of these stars, which might have some relevance to their origins.
As a sequel to the Li observations by Balachandran, Lambert & Stauffer (1988, 1996) in 35 stars of the 50 Myr old cluster α Persei, we have obtained and analyzed high resolution spectra of another 51 stars. Following a reconsideration of the cluster membership of the stars (Prosser 1992, Makarov 2006, Mermilliod et al. 2008, and Patience et al. 2002), we discuss the Li abundances for 70 stars. With our larger sample, we reexamine the question of whether the scatter in Li abundance at a given Teff seen in young clusters at cool temperatures is real or not.
