Mortality from gastrointestinal congenital anomalies at 264 hospitals in 74 low-, middle- and high-income countries: a multicentre, international, prospective cohort study
No full textBackground: congenital anomalies are the 5th leading cause of under-5 mortality, globally. Many gastrointestinal congenital anomalies are fatal without timely access to neonatal surgical care. Limited literature exists on these conditions in low- and middle-income countries (LMICs). We compared the outcomes of the seven commonest gastrointestinal congenital anomalies in low-, middle- and high-income countries (LICs, MICs, and HICs), globally, and identified factors associated with mortality.
Methods: the Global PaedSurg Research Collaboration, consisting of healthcare professionals who provide surgical care for neonates and children with congenital anomalies, performed a multicentre, international prospective cohort study of consecutive patients, under 16 years, presenting to hospital for the first time with oesophageal atresia, congenital diaphragmatic hernia, intestinal atresia, gastroschisis, exomphalos, anorectal malformation, and Hirschsprung’s Disease. Recruitment was for a minimum of 1-month between October 2018 and April 2019. We collected data on patient demographics, clinical status, interventions, and outcomes using REDCap. Follow-up was to 30 days post-primary intervention. The primary outcome was all-cause, in-hospital mortality for all conditions combined and each condition individually, stratified by country income status. We used chi-squared to compare mortality between country income strata, and penalised regression to identify factors associated with mortality (Risk Ratio [RR], 95% Confidence Interval [CI], p value).
Findings: we included 3849 patients with 3975 study conditions (560 oesophageal atresia, 448 congenital diaphragmatic hernia, 681 intestinal atresia, 453 gastroschisis, 325 exomphalos, 991 anorectal malformation, and 517 Hirschsprung’s Disease) from 264 hospitals (89 HICs, 166 MICs, 9 LICs) in 74 countries. Mortality amongst all patients was 39·8% (37/93) in LICs, 20·4% (583/2860) in MICs, and 5·6% (50/896) in HICs (p<0·001 between all country income groups). Gastroschisis had the greatest difference in mortality between country income strata (90·0% [9/10] LICs, 31·9% [97/304] MICs, 1·4% [2/139] HICs, p<0·001 between all country income groups). Factors significantly associated with higher mortality for all patients combined included: country income status (LIC [RR 2·78, CI 1·88-4·11, p<0·001], MIC [RR 2·11, CI 1·59-2·79, p<0·001] vs HIC), sepsis at presentation (RR 1·20, CI 1·04-1·40, p=0·016), higher American Society of Anesthesiologists score (ASA) at primary intervention (ASA 4-5 [RR 1·82, CI 1·40-2·35, p<0·001], ASA 3 [RR 1·58, CI 1·30-1·92, p<0·001] vs ASA 1-2), surgical safety checklist not used (RR 1·39, CI 1·02-1·90, p=0·035), and ventilation or parenteral nutrition unavailable when needed (RR 1·96, CI 1·41-2·71, p<0·001, or RR 1·35, CI 1·05-1·74, p=0·018, respectively). Administration of parenteral nutrition (RR 0·61, CI 0·47-0·79, p<0·001), and use of a peripherally inserted central catheter (RR 0·65, CI 0·5-0·86, p=0·002), or percutaneous central line (RR 0·69, CI 0·48-1·00, p=0·049) were associated with lower mortality.
Interpretation: unacceptable differences in mortality exist for gastrointestinal congenital anomalies between low-, middle- and high-income countries. Improving access to quality neonatal surgical care in LMICs is vital to achieve Sustainable Development Goal 3·2 to ‘end preventable deaths in neonates and children under five by 2030’.

Also By The Same Author: AKTiveAuthor, a Citation Graph Approach to Name Disambiguation
No full textThe desire for definitive data and the semantic web drive for inference over heterogeneous data sources requires co-reference resolution to be performed on those data. In particular, name disambiguation is required to allow accurate publication lists, citation counts and impact measures to be determined. This paper describes a graph-based approach to author disambiguation on large-scale citation networks. Using self-citation, co-authorship and document source analyses, AKTiveAuthor clusters papers, achieving precision of 0.997 and recall of 0.818 over a test group of eight surname clusters
Effect of struts and central tower on aerodynamics and aeroacoustics of vertical axis wind turbines using mid-fidelity and high-fidelity methods
Full text linkThis study investigates the impact of struts and a central tower on the aerodynamics and aeroacoustics of Darrieus Vertical Axis Wind Turbines (VAWTs) at chord-based Reynolds numbers of 8.12 × 104. A 2-bladed H-Darrieus VAWT is used, featuring a 1.5m diameter, a solidity of 0.1 and a blade cross-section of symmetrical NACA 0021. The turbine design is kept simple and straight-bladed which is essential for isolating and analyzing the specific effects of struts and a tower. The high-fidelity Lattice Boltzmann Method (LBM) in PowerFLOW 6-2020 and the mid-fidelity Lifting Line Free Vortex Wake (LLFVW) method in QBlade 2.0 are employed, with the mid-fidelity method providing a faster analytical tool for insights into the turbine performance. Firstly, both the LLFVW (mid-fidelity) and LBM (high-fidelity) methods effectively capture the general trends observed in VAWT power performance. However, the former predicts mean thrust values that are approximately 10% higher, and mean torque values that are approximately 19% higher, in comparison to the latter. Subsequently, the former predicts lower streamwise wake velocities relative to those predicted by the latter. These differences increase in configurations that include struts and a tower (to 30% - 31%). Secondly, the presence of struts and a tower leads to a reduction in both mean power (by 15% to 55%) and thrust (by 3% to 3.6%), with a further small decrease observed when doubling the tower diameter (power and thrust both by 0.5% to 3%). The struts predominantly affect the spanwise distribution of blade loading, while the tower impacts the azimuthal variation of blade loading. Additionally, the addition of struts and a tower reduces low-frequency noise (50-200 Hz) while increasing high-frequency noise (> 300 Hz). The observed decrease in mean blade loading results in reduced low-frequency noise, while the increase in high-frequency noise is ascribed to the increased intensity of BWI/BVI leading to higher unsteady loading fluctuations on blades.Wind Energ
Ep. #181 - Nigel Clark
No full textThis recording and transcript form part of a collection of podcasts conducted by the Cultures of Energy at Rice University. Cultures of Energy brings writers, artists and scholars together to talk, think and feel their way into the Anthropocene. We cover serious issues like climate change, species extinction and energy transition. But we also try to confront seemingly huge and insurmountable problems with insight, creativity and laughter.Cymene and Dominic discuss a strange effort to police sugar packet play on this week’s podcast. Then (15:52) we are delighted to welcome Nigel Clark to the conversation. Nigel is Chair of Social Sustainability and Human Geography at Lancaster University (https://www.lancaster.ac.uk/lec/about-us/people/nigel-clark ). He is the author of Inhuman Nature: Sociable Life on a Dynamic Planet (2011) and co-editor of Atlas: Geography, Architecture and Change in an Interdependent World (2012), Material Geographies (2008) and Extending Hospitality(2009). We start things off by talking about a new book he is working on called The Anthropocene and Societythat he is working on with Bron Szerszynski and what it means to rethink humanity through planetary strata, flows, and multiplicity. We turn from there to Australian feminism, phosphates, Aotearoa New Zealand as a space of settler grassland experiments, wealth, and geocide. Then we touch on fire and its excess, our brittle life on an earth’s surface caught between solar and geothermal vitalities, metamorphosis, the early connection between gunpowder and combustion engines and European geotrauma. A special birthday week shout-out to our very own eternal Cymene Howe :

Political Parties and Web 2.0: The Liberal Democrat Perspective
No full textPolitical parties have been criticised for their limited use of interactivity via their Internet presences,
largely it is suggested because they seek to control their online messages. This article will consider
interactivity from the perspective of a political party, the Liberal Democrats, using their Freedom
Bill online campaign as a case study. We suggest that the Liberal Democrats use ‘weak interactivity’
because of internal policymaking concerns, and their belief that as a political party they are
promoting their ideas, not co-creating a new product. Thus we suggest interaction should be closer
to a formal consultation than a face-to-face dialogue
