Recent changes to US research funding are having far-reaching consequences that imperil the integrity of science and the provision of care to vulnerable populations. Resisting these changes, the BJPsych Portfolio reaffirms its commitment to publishing mental science and advancing psychiatric knowledge that improves the mental health of one and all.
Children and youth have tended to be under-reported in the historical scholarship. This collection of essays recasts the historical narrative by populating premodern Scottish communities from the thirteenth to the late eighteenth centuries with their lively experiences and voices. By examining medieval and early modern Scottish communities through the lens of age, the collection counters traditional assumptions that young people are peripheral to our understanding of the political, economic, and social contexts of the premodern era. The topics addressed fall into three main sections: theexperience of being a child/adolescent; representations of the young; and the construction of the next generation. The individual essays examine the experience of the young at all levels of society, including princes and princesses, aristocratic and gentry youth, urban young people, rural children, and those who came to Scotland as slaves; they draw on evidence from art, personal correspondence, material culture, song, legal and government records, work and marriage contracts, and literature.

Fontan survivors have depressed cardiac index that worsens over time. Serum biomarker measurement is minimally invasive, rapid, widely available, and may be useful for serial monitoring. The purpose of this study was to identify biomarkers that correlate with lower cardiac index in Fontan patients.
Methods and results
This study was a multi-centre case series assessing the correlations between biomarkers and cardiac magnetic resonance-derived cardiac index in Fontan patients ⩾6 years of age with biochemical and haematopoietic biomarkers obtained ±12 months from cardiac magnetic resonance. Medical history and biomarker values were obtained by chart review. Spearman’s Rank correlation assessed associations between biomarker z-scores and cardiac index. Biomarkers with significant correlations had receiver operating characteristic curves and area under the curve estimated. In total, 97 cardiac magnetic resonances in 87 patients met inclusion criteria: median age at cardiac magnetic resonance was 15 (6–33) years. Significant correlations were found between cardiac index and total alkaline phosphatase (−0.26, p=0.04), estimated creatinine clearance (0.26, p=0.02), and mean corpuscular volume (−0.32, p<0.01). Area under the curve for the three individual biomarkers was 0.63–0.69. Area under the curve for the three-biomarker panel was 0.75. Comparison of cardiac index above and below the receiver operating characteristic curve-identified cut-off points revealed significant differences for each biomarker (p<0.01) and for the composite panel [median cardiac index for higher-risk group=2.17 L/minute/m2 versus lower-risk group=2.96 L/minute/m2, (p<0.01)].
Conclusions
Higher total alkaline phosphatase and mean corpuscular volume as well as lower estimated creatinine clearance identify Fontan patients with lower cardiac index. Using biomarkers to monitor haemodynamics and organ-specific effects warrants prospective investigation.
We demonstrate the gravure printing of a high-performance indacenodithiophene (IDT) copolymer, indacenodithiophene–benzothiadiazole (C16IDT–BT), onto self-aligned organic field-effect transistor architectures on flexible plastic substrates. We observed that the combination of a gravure-printed dielectric with gravure-printed semiconductor yielded devices with higher mean-effective mobility than devices manufactured using photolithographically patterned dielectric. Peak mobilities of μ = 0.1 cm2 V−1 s−1 were measured, and exceed previous reports for non-printed C16IDT-BT on non-flexible silicon substrates.
The Coral Triangle Initiative is an ambitious attempt to conserve the marine biodiversity hotspot known as the Coral Triangle. However, the reef fauna in many nearby regions remains poorly explored and, consequently, the focus on the Coral Triangle risks overlooking other areas of high conservation significance. One region of potential significance, Aceh, Indonesia, has not been visited by coral taxonomists since the Dutch colonial period. Here we document the species richness of scleractinian corals of Pulau Weh, Aceh. We also compare the species richness of the genus Acropora at 3–5 sites in each of nine regions in Indonesia and Papua New Guinea. Although dominated by widespread Indo-Pacific species, the coral fauna of Pulau Weh is also the eastern and western boundary for many Indian Ocean and Pacific Ocean species, respectively. We identified a total of 133 scleractinian species, of which three have been previously recorded only in the western Indian Ocean and five are presently undescribed. The mean species richness of the Acropora at Pulau Weh is similar to regions within the Coral Triangle. This high species richness plus the high proportion of endemics suggests that the Andaman Sea is of similarly high conservation value to the Coral Triangle. We suggest that an international initiative similar to the Coral Triangle Initiative is required to conserve this region, which includes the territorial waters of six countries.
