No full textDischarge from the emergency department and early hospital revaluation in patients with COVID-19 pneumonia: a prospective study
No full textObjective The national health systems are currently facing the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic. We assessed the efficacy of outpatient management for patients with SARS-CoV-2 related pneumonia at risk of progression after discharge from the emergency department. Methods This was a single-center prospective study. We enrolled patients with confirmed SARS-CoV-2 pneumonia, without hypoxemic respiratory failure, and at least one of the following: age ≥ 65 years or the presence of relevant comorbidities or pneumonia extension > 25% on high resolution computed tomography. Patients with pneumonia extension > 50% were excluded. An ambulatory visit was performed after at least 48 hours, when patients were either discharged, admitted, or deferred for a further visit. As a control, we evaluated a comparable historical cohort of hospitalized patients. Results A total of 84 patients were enrolled (51 male patients; mean age, 62.8 years). Two-thirds of the patients had at least one comorbidity and 41.6% had a lung involvement > 25% on high resolution computed tomography; the mean duration of symptoms was 8.0±3.0 days, and the mean PaO2/FiO2 ratio was 357.5±38.6. At the end of the follow-up period, 69 patients had been discharged, and 15 were hospitalized (mean stay of 6 days). Older age and higher National Early Warning Score 2 were significant predictors of hospitalization at the first follow-up visit. One hospitalized patient died of septic shock. In the control group, the mean hospital stay was 8 days. Conclusion Adopting a “discharge and early revaluation” strategy appears to be safe, feasible, and may optimize hospital resources during the SARS-CoV-2 pandemic

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

BACKGROUND: About 20% of patients with unprovoked venous thromboembolism have a
recurrence within 2 years after the withdrawal of oral anticoagulant therapy.
Extending anticoagulation prevents recurrences but is associated with increased
bleeding. The benefit of aspirin for the prevention of recurrent venous
thromboembolism is unknown.
METHODS: In this multicenter, investigator-initiated, double-blind study,
patients with first-ever unprovoked venous thromboembolism who had completed 6 to
18 months of oral anticoagulant treatment were randomly assigned to aspirin, 100
mg daily, or placebo for 2 years, with the option of extending the study
treatment. The primary efficacy outcome was recurrence of venous thromboembolism,
and major bleeding was the primary safety outcome.
RESULTS: Venous thromboembolism recurred in 28 of the 205 patients who received
aspirin and in 43 of the 197 patients who received placebo (6.6% vs. 11.2% per
year; hazard ratio, 0.58; 95% confidence interval [CI], 0.36 to 0.93) (median
study period, 24.6 months). During a median treatment period of 23.9 months, 23
patients taking aspirin and 39 taking placebo had a recurrence (5.9% vs. 11.0%
per year; hazard ratio, 0.55; 95% CI, 0.33 to 0.92). One patient in each
treatment group had a major bleeding episode. Adverse events were similar in the
two groups.
CONCLUSIONS: Aspirin reduced the risk of recurrence when given to patients with
unprovoked venous thromboembolism who had discontinued anticoagulant treatment,
with no apparent increase in the risk of major bleeding. (Funded by the

The Right to Strike under the United States Constitution: Theory, Practice, and Possible Implications for Canada
No full textAnswering critics of the Canadian Supreme Court's judgment in B.C. Health, the author argues that the Court laid the foundation for a principled and durable doctrine protecting constitutional labour rights, one that goes directly to the heart of the matter — the inequality of workers’ power in the employment relation. In the author’s view, two paths could lead from B.C. Health to the recognition of Charter protec- tion for a right to strike: one that treats the right as an accessory to col- lective bargaining, and one that upholds the right directly on the basis of the Charter values of equality and participation. The author supports the latter approach, contending that constitutional rights should be defined in relation to fundamental values, in a way that is not contingent on time-bound or fact-sensitive assessments about the role of strikes within a particular collective bargaining regime. Although a Charter right to strike may involve the courts in difficult choices about when to defer to legislative policy decisions, and courts may lack the institutional capac- ity to deal effectively with labour law issues, the author points out that judges can look to ILO standards for expert guidance. Noting that the U.S. experience in this area might be of considerable use to Canadians, the author concludes by providing an overview of American case law concerning a constitutional right to strike.Peer reviewe
G-Rank: Unsupervised Continuous Learn-to-Rank for Edge Devices in a P2P Network
No full textRanking algorithms in traditional search engines are powered by enormous training data sets that are meticulously engineered and curated by a centralized entity. Decentralized peer-to-peer (p2p) networks such as torrenting applications and Web3 protocols deliberately eschew centralized databases and computational architectures when designing services and features. As such, robust search-and-rank algorithms designed for such domains must be engineered specifically for decentralized networks, and must be lightweight enough to operate on consumer-grade personal devices such as a smartphone or laptop computer. We introduce G-Rank, an unsupervised ranking algorithm designed exclusively for decentralized networks. We demonstrate that accurate, relevant ranking results can be achieved in fully decentralized networks without any centralized data aggregation, feature engineering, or model training. Furthermore, we show that such results are obtainable with minimal data preprocessing and computational overhead, and can still return highly relevant results even when a user’s device is disconnected from the network. G-Rank is highly modular in design, is not limited to categorical data, and can be implemented in a variety of domains with minimal modification. The results herein show that unsupervised ranking models designed for decentralized p2p networks are not only viable, but worthy of further research.https://github.com/awrgold/G-RankComputer Scienc
