Infants born with cardiac abnormalities causing dependence on the arterial duct for pulmonary blood flow are often palliated a shunt usually between subclavian artery and either artery. A so-called modified Blalock-Taussig allows progress through early life to an age weight at which repair or further more stable palliation can be safely achieved. Modified shunts continue present concern postprocedural instability mortality such that other alternatives explored. Duct stenting (DS) is emerging...
Free Thermohaline Convection Beneath Allochthonous Salt Sheets: An Agent for Tectonics and Fluid Flow in Gulf Coast Sediments
Geological processes of fluid transport and chemical reaction in sedimentary basins have formed many the earth's energy mineral resources. These can be analyzed on natural time distance scales with use supercomputers. Numerical experiments are presented that give insights to factors controlling subsurface pressures, temperatures, reactions; origin ores; distribution quality hydrocarbon reservoirs. The results show numerical analysis combined stratigraphic, sea level, plate tectonic histories...
To evaluate the effectiveness of a web based decision aid versus leaflet versus, usual practice in reducing parents' decisional conflict for first dose MMR vaccination decision. The, impact on vaccine uptake was also explored.Three-arm cluster randomised controlled trial.Fifty GP practices north of, England.220 time parents making decision.Web, plus practice, only, (control).Decisional primary outcome and used as the, measure levels informed decision-making. secondary outcome.Decisional...
The current paradigm for causal inference in epidemiology relies primarily on the evaluation of counterfactual contrasts via statistical regression models informed by graphical (often form directed acyclic graphs, or DAGs) and their underlying mathematical theory. However, there have been growing calls supplementary methods, one such method that has proposed is agent-based modelling due to its potential simulating counterfactuals. within epidemiological literature, currently exists a general...
In the UK public concern about safety of combined measles, mumps and rubella [MMR] vaccine continues to impact on MMR coverage. Whilst sharp decline in uptake has begun level out, first second dose rates remain short that required for population immunity. Furthermore, international research consistently shows some parents lack confidence making a decision vaccination their children. Together, this work suggests effective interventions are support make informed decisions MMR. This trial...
ABSTRACT Background Directed acyclic graphs (DAGs) are an increasingly popular approach for identifying confounding variables that require adjustment when estimating causal effects. This review examined the use of DAGs in applied health research to inform recommendations improving their transparency and utility future research. Methods Original articles published during 1999-2017 mentioning “ directed ” or similar citing DAGitty were identified from Scopus, Web Science, Medline, Embase. Data...
Introduction: Increasing demand for ultrasound services is reducing learners’ access to medical clinical experience. High-fidelity simulation equipment, such as the BodyWorks Eve®, enhances experience and scanning ability. This has potential improve patient safety ability detect, identify accurately report a known pathology can be assessed, which not possible in practice. Methods: Participants performed one pathological examination on Eve® participants’ performance level was assessed by...
The serious scholar of petrology is well aware the discrepant level understanding that exists between igneous and metamorphic petrogenesis sediment diagenesis (also known as postdepositional evolution). While nucleation crystallization theory, phase equilibria, principles heat mass transport have provided guidance for scientists to understand formation subsequent evolution rocks, sedimentary petrologists seem been left behind in detailed, descriptive characterization, with little chemical...

Stage of disease and socioeconomic background (SEB) are often used to 'explain' differences in breast cancer outcomes. There challenges for all types analysis (eg, survival analysis, logistic regression), including missing data, measurement error the 'reversal paradox'. This study investigates association between SEB status within 5 years diagnosis using (1) regression with without adjustment stage (2) latent class (LCA) excluding as a covariate but predictor.Women diagnosed invasive 1998...
