A bloom of the colonial microalga Phaeocystis pouchetii was advected from ice-free waters to beneath 1.5 m annual fast ice in East McMurdo Sound, Antarctica late December 1984. Strategies photoadaptation a reduction growth irradiance involved 3- 4-fold increase photosynthetic efficiency per chlorophyll (αb) and 2- 3-fold cell (αc). The index (Ik) decreased by 50% on both cellular basis. In situ production under sea Sound is estimated contribute 16 g carbon m−2 annually, value comparable with...
We aimed to develop a distributed, immutable, and highly available cross-cloud blockchain system facilitate federated data analysis activities among multiple institutions.
Health systems generate and store vast amounts of clinical data, requiring structured processes to ensure that secondary use the data is available researchers in an efficient, ethical, secure manner. We describe a process provide health system at large, multi-hospital balances efficiency with security ethics. The Honest Enterprise Research Broker (HERB) Committee has enacted systematic deliver investigators requesting using pre-written SQL code, when possible, increase efficiency, providing...
Abstract Objective To utilize, in an individual and institutional privacy-preserving manner, electronic health record (EHR) data from 202 hospitals by analyzing answers to COVID-19-related questions posting these online. Materials Methods We developed a distributed, federated network of 12 systems that harmonized their EHRs submitted aggregate consortia posted at https://www.covid19questions.org. Our consortium processes implemented distributed algorithms produce variety questions. were able...
Abstract Background Patients often seek medical treatment among different health care organizations, which can lead to redundant tests and treatments. One electronic record (EHR) platform, Epic Systems, uses a patient linkage tool called Care Everywhere (CE), match patients across institutions. To the extent that such linkages accurately identify shared they would hold potential for improving care. Objective This study aimed understand how accurate CE with default settings is identical...
Abstract There are nine “giant vertical” neurons in the lobula plate of fly optic lobe. Intracellular recordings were obtained from three most peripheral these cells. These cells respond to a light flash with graded changes membrane potential. The response consists an “on” transient, sustained depolarization, increase potential fluctuations, and “off” transient. Signal averaging showed that only transients correlated stimulus. A pattern horizontally oriented stripes moving vertical direction...
To demonstrate a process of calculating the maximum potential morphine milligram equivalent daily dose (MEDD) based on prescription Sig for use in quality improvement initiatives. calculate an opioid prescription's Sig-MEDD, we developed SQL code to determine units/day using discrete field data and text-parsing instructions. We validated derived calculation 3000 Sigs, then compared Sig-MEDD against Epic-MEDD calculator. Of 101 782 outpatient prescriptions ordered over 1 year, 80% used...
Patient portals allow communication with clinicians, access to test results, appointments, etc, and generally requires another set of log-ins passwords, which can become cumbersome, as patients often have records at multiple institutions. Social credentials (eg, Google Facebook) are increasingly used a federated identity reduce the password burden. Single Federated Identity Log-in for Electronic health (Single-FILE) is real-world feasibility acceptability social their electronic (EHRs)...
In the West model of zonal distribution pulmonary blood flow, increases in flow down zone 2 are attributed to an increase driving pressure and a decrease resistance resulting from recruitment distension. The 3 is only. Recent studies indicate that, besides required maintain through vessel, there added cost that must be overcome order initiate flow. These additional costs designated critical pressures (Pcrit). Because Pcrit exceed alveolar pressure, distinction between zones becomes less...
We studied the relationship between pulmonary artery wedge pressure (Pw) and venous (Ppv) at 2 aveolar pressures (Pa) in 7 isolated perfused dog lobes. If Pa were critical circulation, one would expect Pw to equal Ppv for all > Pa. Relative hilum, average these lobes was 15.07 ± 0.40 cmH2O = 5 increased significantly 17.23 0.82 cmH2O. Because fact exceeded Pa, found be relatively constant independent of even when by or more. For example, 5.13 0.04 9.64 0.28, mean value 13.30 0.59 is neither...
<sec> <title>BACKGROUND</title> Patient decision aid (PDAs) are important tools that support informed decision-making by the patient based on evidence-based treatment options. PDAs can increase knowledge, reduce decisional regret, and engage provider in meaningful dialog. Despite proven effectiveness enhancing patient-centered care improve outcomes, a gap remains of implementing routine clinical workflows. </sec> <title>OBJECTIVE</title> This qualitative study produced insight into needs...
Introduction The total impact of the current COVID-19 pandemic on cancer screenings and diagnostic procedures by race ethnicity has not yet been fully characterized. Methods In this study, we compared ethnic racial differences in screening for breast, colon, prostate them to population-level SARS-CoV2 infection rates United States between January 2019 2021. Results A significant reduction all activities was observed March May 2020, with largest relative decline April during initial surge....
There is an urgent need to answer questions related COVID-19's clinical course and associations with underlying conditions health outcomes. Multi-center data are necessary generate reliable answers, but centralizing in a single repository not always possible. Using privacy-protecting strategy, we launched public Questions & Answers web portal (https://covid19questions.org) analyses of comorbidities, medications laboratory tests using from 202 hospitals (59,074 COVID-19 patients) the USA...
Abstract Background The diagnosis of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)–associated multisystem inflammatory in adults (MIS-A) requires distinguishing it from disease 2019 (COVID-19) and may affect clinical management. Methods In this retrospective cohort study, we applied the US Centers for Disease Control Prevention case definition to identify hospitalized with MIS-A at 6 academic medical centers 1 March 2020 31 December 2021. Patients were matched by age group,...
