The Eighth World Congress of Pediatric Cardiology and Cardiac Surgery (WCPCCS) will be held in Washington DC, USA, from Saturday, 26 August, 2023 to Friday, 1 September, 2023, inclusive. The Eighth World Congress of Pediatric Cardiology and Cardiac Surgery will be the largest and most comprehensive scientific meeting dedicated to paediatric and congenital cardiac care ever held. At the time of the writing of this manuscript, The Eighth World Congress of Pediatric Cardiology and Cardiac Surgery has 5,037 registered attendees (and rising) from 117 countries, a truly diverse and international faculty of over 925 individuals from 89 countries, over 2,000 individual abstracts and poster presenters from 101 countries, and a Best Abstract Competition featuring 153 oral abstracts from 34 countries. For information about the Eighth World Congress of Pediatric Cardiology and Cardiac Surgery, please visit the following website: [www.WCPCCS2023.org]. The purpose of this manuscript is to review the activities related to global health and advocacy that will occur at the Eighth World Congress of Pediatric Cardiology and Cardiac Surgery.

Acknowledging the need for urgent change, we wanted to take the opportunity to bring a common voice to the global community and issue the Washington DC WCPCCS Call to Action on Addressing the Global Burden of Pediatric and Congenital Heart Diseases. A copy of this Washington DC WCPCCS Call to Action is provided in the Appendix of this manuscript. This Washington DC WCPCCS Call to Action is an initiative aimed at increasing awareness of the global burden, promoting the development of sustainable care systems, and improving access to high quality and equitable healthcare for children with heart disease as well as adults with congenital heart disease worldwide.

OBJECTIVES/GOALS: Recent NCATS funding announcements emphasize pursuing domain-agnostic translational science projects that seek to transform the system of science. We aimed to articulate the social responsibility of translational science, defined as prioritizing improved health outcomes and decreased disparities. METHODS/STUDY POPULATION: We focused on the framing of social responsibilities of translational science and distinctions between (a) domain-agnostic translational science that aims to transform the system of science and (b) translational research that takes place within a specific therapeutic area. We reviewed CTSA funding calls, translational research ethics papers, and statements by leaders in the field of translational science. We integrated the social responsibilities of improving health outcomes and decreasing disparities with the values of translational science, which prioritize the relevance, usability, and sustainability of translational interventions. RESULTS/ANTICIPATED RESULTS: We drew on our review of the literature and case studies to offer guidance aimed at helping to ensure that differently positioned actors and entities within the translational ecology can advance the values of translational science while also fulfilling the social responsibilities of translational science. We specify how (a) Funders and policymaking institutions, (b) Organizations such as research universities and CTSA institutes, (c) Translational health science teams working on innovative translational science projects, and (d) Individual translational scientists can all contribute to ensuring that translational science fulfills its ethical obligations and social responsibilities. DISCUSSION/SIGNIFICANCE: The social responsibility of translational science can be fulfilled by centering its efforts to develop useful, sustainable, and relevant innovations. These criteria clarify how social responsibilities manifest in practice and can help funders shape and guide the next era of translational discovery.

This paper connects two trends in contemporary legal scholarship that do not often intersect, namely commentary on the increasingly diverse nature of family law advice and support services, and calls for a refresh of the regulatory environment in which legal services in general are provided. Focusing on the law and landscape in England and Wales, we argue that regulatory challenges are particularly acute in the field of family law, where the range and reach of services provided by non-lawyers is extraordinary. We illustrate how particular aspects of debates over regulating and diversifying legal services apply to the family law context, noting that such concerns as there are have not always been well targeted. Finally, we identify a sub-set of innovative ‘extra-legal’ services that set private family law even further apart from other sub-fields of law when it comes to regulatory and professional challenge. These services clearly sit inside the landscape of family dispute resolution but equally clearly fall outside the boundaries of what is usually considered ‘legal’. This, we suggest, highlights the need for a concerted effort to define the contours of family law and family legal services so that a holistic approach might be taken to understanding and managing the standards and effectiveness of different service and support types.

Despite promising steps towards the elimination of hepatitis C virus (HCV) in the UK, several indicators provide a cause for concern for future disease burden. We aimed to improve understanding of geographical variation in HCV-related severe liver disease and historic risk factor prevalence among clinic attendees in England and Scotland. We used metadata from 3829 HCV-positive patients consecutively enrolled into HCV Research UK from 48 hospital centres in England and Scotland during 2012–2014. Employing mixed-effects statistical modelling, several independent risk factors were identified: age 46–59 y (ORadj 3.06) and ≥60 y (ORadj 5.64) relative to <46 y, male relative to female sex (ORadj 1.58), high BMI (ORadj 1.73) and obesity (ORadj 2.81) relative to normal BMI, diabetes relative to no diabetes (ORadj 2.75), infection with HCV genotype (GT)-3 relative to GT-1 (ORadj 1.75), route of infection through blood products relative to injecting drug use (ORadj 1.40), and lower odds were associated with black ethnicity (ORadj 0.31) relative to white ethnicity. A small proportion of unexplained variation was attributed to differences between hospital centres and local health authorities. Our study provides a baseline measure of historic risk factor prevalence and potential geographical variation in healthcare provision, to support ongoing monitoring of HCV-related disease burden and the design of risk prevention measures.

The significant extinctions in Earth history have largely been unpredictable in terms of what species perish and what traits make species susceptible. The extinctions occurring during the late Pleistocene are unusual in this regard, because they were strongly size-selective and targeted exclusively large-bodied animals (i.e., megafauna, >1 ton) and disproportionately, large-bodied herbivores. Because these animals are also at particular risk today, the aftermath of the late Pleistocene extinctions can provide insights into how the loss or decline of contemporary large-bodied animals may influence ecosystems. Here, we review the ecological consequences of the late Pleistocene extinctions on major aspects of the environment, on communities and ecosystems, as well as on the diet, distribution and behavior of surviving mammals. We find the consequences of the loss of megafauna were pervasive and left legacies detectable in all parts of the Earth system. Furthermore, we find that the ecological roles that extinct and modern megafauna play in the Earth system are not replicated by smaller-bodied animals. Our review highlights the important perspectives that paleoecology can provide for modern conservation efforts.

When compared with the general population, people living with severe mental illness (SMI) are 1·8 times more likely to have obesity while in adult mental health secure units, rates of obesity are 20 % higher than the general population. In England, there are currently 490 000 people living with SMI. The aim of this systematic review was to collate and synthesise the available quantitative and qualitative evidence on a broad range of weight management interventions for adults living with SMI and overweight or obesity. Primary outcomes were reductions in BMI and body weight. Following sifting, eighteen papers were included in the final review, which detailed the results of nineteen different interventions; however, there was a lack of qualitative evidence. Pooled results for three studies (MD − 3·49, 95 % CI − 6·85, −0·13, P = 0·04) indicated a small effect in terms of body weight reduction but no effect on BMI for four studies (MD − 0·42, 95 % CI − 1·27, 0·44, P = 0·34). Key recommendations for future research included integration of qualitative methodology into experimental study design, a review of outcome measures and for study authors to follow standardised guidelines for reporting to facilitate complete and transparent reporting.
