Advocacy at the Eighth World Congress of Pediatric Cardiology and Cardiac Surgery.

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.

C-reactive protein guided use of procalcitonin in COVID-19

Low procalcitonin (PCT) concentrations (<0.5ng/mL) can facilitate exclusion of bacterial co-infection in viral infections, including COVID-19. However, costs associated with PCT measurement preclude universal adoption, indicating a need to identify settings where PCT provides clinical information beyond that offered by other inflammatory markers, such as C-reactive protein (CRP) and white cell count (WCC). In an unselected cohort of 299 COVID-19 patients, we tested the hypothesis that PCT<0.5ng/mL was associated with lower levels of CRP and WCC. We demonstrated that CRP values below the geometric mean of the entire patient population had a negative predictive value for PCT<0.5ng/mL of 97.6% and 100% at baseline and 48 hours into admission respectively, and that this relationship was not confounded by intensive care admission or microbiological findings. CRP-guided PCT testing algorithms can reduce costs and support antimicrobial stewardship strategies in COVID-19.
