- Abstract
Maker culture has expanded from its traditional niches (people with an interest in computers, programming and the digital world in general) to other, more general fields such as education, business and government. However, “despite the interest in the Maker Movement and its connection to formal and informal education, there has been little research concerning the direction it is taking, the opportunities it could present for education, and why” (Papavlasopoulou in Entertainment Computing 18, 57–78, 2017). In this chapter, we developed a pedagogical framework for seamless learning in Fab Lab activities based on the multiple levels of interactivity that different tools, activities and the contexts enable. The aim is to use age-appropriate activities and appropriate tools, as suggested by Blikstein (FabLab: Of Machines, Makers and Inventors. Transcript, Bielefeld, Germany, pp. 173–180, 2013). In this chapter, we introduce the theoretical principles of the framework—computational thinking, computational making and design-driven education—as a model to teach twenty-first-century skills. We also illustrate the pedagogical principles with a case study in a primary school (K-12) as an example of designing integrated educational activities to align with the maker activities being performed in the Fab Lab context.

Introduction: A fragility fracture is a clinical manifestation of osteoporosis and a major risk factor for subsequent fracture in adults aged 50+, yet adherence to secondary prevention strategies is lacking internationally. This retrospective observational study aimed to characterize post-fracture management in the Canadian primary care setting. Methods: A cohort of 778 patients with an index fragility fracture occurring between January 1, 2014 and December 1,2016 was identified from medical records reviewed at 76 primary care centers in Canada, with follow-up until January 2018. Fragility fracture was defined as a fracture occurring without major trauma at any skeletal site other than the skull, face, cervical spine, hand, metatarsus, phalanges or patella. Patients were excluded if they had a history of fragility fracture in the five years prior to their index fracture. Results: Of all 778 patients identified (80.5% female, median age [IQR] 73 [64-80]), 215 were on osteoporosis treatment and 269 had osteoporosis diagnosis recorded prior to their index fracture. The median follow-up after index fracture was 363 (IQR 91-808) days. Of patients not on osteoporosis treatment at their index fracture, 60.2% (n = 339 of 563) remained untreated after their index fracture and 62.2% (n = 23 of 37) continued untreated after their subsequent fracture. After their index fracture, fracture risk assessment (FRAX or CAROC) was not performed in 83.2% (n = 647 of 778) of patients, and 59.9% (n = 466 of 778) of patients did not receive BMD testing. Of patients with available data who did not have osteoporosis diagnosis recorded prior to their index date, 61.3% (n = 300 of 489) remained undiagnosed over the interval from index fracture to the end of follow-up. At least one subsequent fracture occurred in 11.5% (n = 86 of 778) of patients after their index fracture until the end of study follow-up. Conclusion: In the primary care setting, fragility fracture infrequently resulted in osteoporosis treatment and very infrequently led to fracture risk assessment. Even after experiencing multiple fragility fractures over a relatively short follow-up, the majority of patients remained untreated. These results suggest a fragility fracture is not recognized as a major risk factor for subsequent fracture and its occurrence does not prompt primary care physicians to intervene. These data call forth initiatives to identify and overcome obstacles to primary care physicians' effective management of patients after fragility fractures. [ABSTRACT FROM AUTHOR]

- Abstract
Background: Cardiovascular disease is the second-leading cause of death in Canada. However, limited data are available on the prevalence of atherosclerotic cardiovascular disease (ASCVD) in Canada. The study objective was to describe the incidence and prevalence of ASCVD in adult patients in Ontario, Canada, and to evaluate temporal trends for subsequent ASCVD events among those with new-onset ASCVD., Methods: This retrospective, observational study identified ASCVD incidence and prevalence data from the Institute for Clinical Evaluative Sciences Data Repository for adults from Ontario. Overall prevalence was established for the period from 2002 to 2018. Incident cases from April 1, 2005 to March 2016 were then identified, and followed up to 2018. Primary outcomes were date and type of index event/procedure, patient characteristics/baseline demographics, and comorbidities. Secondary outcomes assessed were time from first to second ASCVD event, subsequent event(s) and/or mortality, and type of subsequent event(s) relative to the type of index/primary event., Results: A total of 1,042,621 eligible prevalent ASCVD cases were identified; of these, 743,309 patients (69%) were newly diagnosed with incident ASCVD. The 10-year prevalence rates for all ASCVD subtypes increased over the study period. Overall event incidence rates per 1000 person-years were mostly stable or increased. Among incident cases, 50% experienced subsequent events over the study period., Conclusions: This observational study demonstrated increasing prevalence and high incidence of new ASCVD diagnoses in adults from Ontario, over the study period. These data, together with the substantial number of subsequent events in ASCVD patients, demonstrate significant clinical burden of this disease in Ontario., (© 2021 The Authors.)

- Abstract
Background: The secondary fracture prevention gap in the osteoporosis field has been previously described as a 'crisis'. Closing this gap is increasingly important in the context of accumulating evidence showing that an incident fragility fracture is associated with an increased risk of subsequent fracture within 1-2 years, known as imminent fracture risk. The objective of this study was to use health services data to characterize the time between index fragility fractures occurring at different osteoporotic sites and subsequent fractures., Methods: This retrospective observational study used de-identified health services data from the publicly funded healthcare system in Ontario, the largest province of Canada. Patients aged > 65 with an index fragility fracture occurring between 2011 and 2015 were identified from the ICES Data Repository using International Classification of Diseases (ICD)-10 codes. We examined median time to subsequent fragility fractures for osteoporotic fracture sites until the end of follow-up (2017). BMD assessment and use of osteoporosis therapies following index fracture were also characterized., Results: Among 115,776 patients with an index fragility fracture, 17.8% incurred a second fragility fracture. Median time between index and second fracture occurring at any site was 555 days (interquartile range: 236-955). For each index fracture site examined, median time from index to second fracture was < 2 years. The proportion of patients with BMD assessment was 10.3% ≤1 year prior to and 16.4% ≤1 year post index fracture. The proportion of patients receiving osteoporosis therapy was 29.8% ≤1 year prior, 34.6% ≤1 year post, and 25.9% > 3 years post index fracture., Conclusions: This cohort of Canadian patients aged > 65 years who experienced a fragility fracture at any site are at imminent risk of experiencing subsequent fracture within the next 2 years and should be proactively assessed and treated.

- Abstract
Northern peatlands have accumulated large stocks of organic carbon (C) and nitrogen (N), but their spatial distribution and vulnerability to climate warming remain uncertain. Here, we used machine-learning techniques with extensive peat core data ( n > 7,000) to create observation-based maps of northern peatland C and N stocks, and to assess their response to warming and permafrost thaw. We estimate that northern peatlands cover 3.7 ± 0.5 million km
2 and store 415 ± 150 Pg C and 10 ± 7 Pg N. Nearly half of the peatland area and peat C stocks are permafrost affected. Using modeled global warming stabilization scenarios (from 1.5 to 6 °C warming), we project that the current sink of atmospheric C (0.10 ± 0.02 Pg C⋅y-1 ) in northern peatlands will shift to a C source as 0.8 to 1.9 million km2 of permafrost-affected peatlands thaw. The projected thaw would cause peatland greenhouse gas emissions equal to ∼1% of anthropogenic radiative forcing in this century. The main forcing is from methane emissions (0.7 to 3 Pg cumulative CH4 -C) with smaller carbon dioxide forcing (1 to 2 Pg CO2 -C) and minor nitrous oxide losses. We project that initial CO2 -C losses reverse after ∼200 y, as warming strengthens peatland C-sinks. We project substantial, but highly uncertain, additional losses of peat into fluvial systems of 10 to 30 Pg C and 0.4 to 0.9 Pg N. The combined gaseous and fluvial peatland C loss estimated here adds 30 to 50% onto previous estimates of permafrost-thaw C losses, with southern permafrost regions being the most vulnerable., Competing Interests: The authors declare no competing interest., (Copyright © 2020 the Author(s).

- Abstract
The National Institutes of Health (NIH) plays a critical role in funding scientific endeavors in biomedicine. Funding innovative science is an essential element of the NIH's mission, but many have questioned the NIH's ability to fulfill this aim. Based on an analysis of a comprehensive corpus of published biomedical research articles, we measure whether the NIH succeeds in funding work with novel ideas, which we term edge science. We find that edge science is more often NIH funded than less novel science, but with a delay. Papers that build on very recent ideas are NIH funded less often than are papers that build on ideas that have had a chance to mature for at least 7 y. We have three further findings. First, the tendency to fund edge science is mostly limited to basic science. Papers that build on novel clinical ideas are not more often NIH funded than are papers that build on well-established clinical knowledge. Second, novel papers tend to be NIH funded more often because there are more NIH-funded papers in innovative areas of investigation, rather than because the NIH funds innovative papers within research areas. Third, the NIH's tendency to have funded papers that build on the most recent advances has declined over time. In this regard, NIH funding has become more conservative despite initiatives to increase funding for innovative projects. Given our focus on published papers, the results reflect both the funding preferences of the NIH and the composition of the applications it receives., Competing Interests: The authors declare no competing interest., (Copyright © 2020 the Author(s).
