Randomised Trial of Block and Replace versus dose titration antithyroid drug treatment in children and adolescents with thyrotoxicosis.
<p><strong>This dataset contains the study regimens for the randomised controlled trial. </strong></p> <p><strong>Context</strong></p> <p>First line treatment of thyrotoxicosis in young people is thionamide antithyroid drug (ATD) in a blocking dose with levothyroxine replacement (block and replace, BR) or in a smaller dose tailored to render the patient euthyroid (dose titration, DT). </p> <p><strong>Objective</strong></p> <p>To determine which regimen provides more stable biochemical control. </p> <p><strong>Design and setting</strong></p> <p>A multi-centre phase III, open-label randomised trial comparing BR with DT in patients aged 2 to 16 years with newly diagnosed thyrotoxicosis at 15 UK centres. Patients were randomised shortly after diagnosis and treated for 3 years. The primary outcome was the percentage of serum thyroid stimulating hormone (TSH) levels in the reference range between 6 months and 3 years. Secondary outcomes included the proportion of Free thyroxine (FT4) levels in the reference range, adverse event frequency and 4y outcome (remission/relapse).</p> <p><strong>Results</strong></p> <p>Eighty-two patients were randomised, with details on clinical course in 81 (62 Female); 40 were allocated to BR (41 DT). Three withdrew with one ineligible. The mean percentage of serum TSH within reference range was 60·2% in BR and 63·8% in DT patients; adjusted difference 4·3%, 95% CI (-7·8 to 16·4);p=0.48. Proportions for FT4 were 79·2% in BR and 85·7% in DT patients; adjusted difference 6·8%, (-0·2 to 15·6);p=0·13. Three patients developed neutropenia – all on BR. 6 BR and 10 DT patients were in remission at 4y. </p> <p><strong>Conclusion</strong></p> <p>This trial has shown no evidence to suggest that BR improves biochemical stability. DT, recommended by American Thyroid Association guidelines, remains the preferred approach in this age group. </p>
Population decline of a long-distance migratory passerine at the edge of its range: nest predation, nest replacement, and immigration
<p class="CxSpFirst">The relative importance of predators and resources (i.e., food) for the dynamics of migratory bird populations is poorly known. Resource availability may be more likely in resource poor environments, but given that nest failure in most systems is due mainly to predation, predator effects may predominate. We document a rapid decline of an isolated Eastern Kingbird (<i>Tyrannus tyrannus</i>) population breeding in the Great Basin Desert of eastern Oregon, USA, and evaluate whether it was driven by limited food resources (water availability ~ food), nest predation, or first-year or adult return rate (RR<sub>J</sub> and RR<sub>A</sub>, respectively) that reflect nonbreeding season events. Most nests failed (~68% of nests) due mainly to nest predation (>90% of failures); nestling starvation was rare. Bioyear precipitation (October-April), breeding season precipitation, and river flow all varied widely but none could account for annual variation in either nest success (NS) or fledging success of successful nest (FSSN). Neither RR<sub>J</sub> nor RR<sub>A</sub> varied with year, any measure of water resources, or reproductive success. Annual population growth rate (ln[N<sub>t+1</sub>/N<sub>t</sub>]) was independent of year, all measures of water availability, RR<sub>J</sub> and RR<sub>A</sub>, and NS of replacement nests, but was high following years of high NS of initial nests; FSSN was also higher in years of high NS. High rates of nest predation, due likely to the expansion of the local American Crow (<i>Corvus brachyrhynchos</i>) population, appeared to drive the population decline. Empirical data and population simulations indicated that replacement nests contributed little to λ, while simulations revealed that, given site-specific vital rates, the decline would have been even greater without immigration (λ = 0.812) than the observed (λ = 0.914). Long distance dispersal may thus be critical for persistence of kingbirds in the naturally highly fragmented habitat that it occupies in the Great Basin Desert.</p>
Social Media Alerts can Improve, but not Replace Hydrological Models for Forecasting Floods
<p>Social media can be used for disaster risk reduction as a complement to traditional information sources, and the literature has suggested numerous ways to achieve this. In the case of floods, for instance, data collection from social media can be triggered by a severe weather forecast and/or a flood prediction. By way of contrast, in this paper we explore the possibility of having an entirely independent flood monitoring system which is based completely on social media, and which is completely self-activated. This independence and self-activation would bring increased robustness, as the system would not depend on other mechanisms for forecasting. We observe that social media can indeed help in the early detection of some flood events that would otherwise not be detected until later, albeit at the cost of many false positives. Overall, our experiments suggest that social media signals should only be used to complement existing monitoring systems, and we provide various explanations to support this argument.</p> <p>This dataset contains the jupyter notebook and related data for running experiments described in the paper along with an additional table with full list of events considered</p>
