M. Kontsevich's graph complex and the Grothendieck-Teichmueller Lie algebra

We show that the zeroth cohomology of M. Kontsevich's graph complex is isomorphic to the Grothendieck-Teichmueller Lie algebra grt_1. The map is explicitly described. This result has applications to deformation quantization and Duflo theory. We also compute the homotopy derivations of the Gerstenhaber operad. They are parameterized by grt_1, up to one class (or two, depending on the definitions). More generally, the homotopy derivations of the (non-unital) E_n operads may be expressed through the cohomology of a suitable graph complex. Our methods also give a second proof of a result of H. Furusho, stating that the pentagon equation for grt_1-elements implies the hexagon equation

Effect of the optimize heart failure care program on clinical and patient outcomes – The pilot implementation in Vietnam

Background: The Ho-Chi-Minh-city Heart Institute in Vietnam took part in the Optimize Heart Failure (OHF) Care Program, designed to improve outcomes following heart failure (HF) hospitalization by increasing patient awareness and optimizing HF treatment. Methods: HF patients hospitalized with left ventricular ejection-fraction (LVEF) <50% were included. Patients received guideline-recommended HF treatment and education. Clinical signs, treatments and outcomes were assessed at admission, discharge, 2 and 6 months (M2, M6). Patients’ knowledge and practice were assessed at M6 by telephone survey. Results: 257 patients were included. Between admission and M2 and M6, heart rate decreased significantly, and clinical symptoms improved significantly. LVEF increased significantly from admission to M6. 85% to 99% of patients received education. At M6, 45% to 78% of patients acquired knowledge and adhered to practice regarding diet, exercise, weight control, and detection of worsening symptoms. High use of renin-angiotensin-aldosterone-system inhibitors (91%), mineralocorticoid-receptor-antagonists (77%) and diuretics (85%) was noted at discharge. Beta-blocker and ivabradine use was less frequent at discharge but increased significantly at M6 (from 33% to 51% and from 9% to 20%, respectively, p < 0.001). There were no in-hospital deaths. Readmission rates at 30 and 60 days after discharge were 8.3% and 12.5%, respectively. Mortality rates at 30 days, 60 days and 6 months were 1.2%, 2.5% and 6.4%, respectively. Conclusions: The OHF Care Program could be implemented in Vietnam without difficulty and was associated with high usage of guideline-recommended drug therapy. Although education was delivered, patient knowledge and practice could be further improved at M6 after discharge

Brief positive psychological interventions within multi-cultural organisational contexts: a systematic literature review

Applications of brief positive psychology interventions (BPPI) within organisational contexts have soared within the last decade; yet academic literature on its effectiveness is limited. However, critics have raised concerns about the applicability, replicability and generalizability of those BPPIs published within academic literature; especially when applied within multi-cultural contexts. Given the ever-increasing diversity of the workforce due to factors such as globalization, migration and immigration, it is imperative to consider cultural context to design effective and meaningful BPPIs. While present literature addresses specific BPPIs in clinical samples and monocultural contexts, limited research exists with respect to the design of BPPIs applicable to multi-cultural organisational contexts. Therefore, the purpose of this chapter is to provide a systematic literature review on multi-cultural BPPIs within organisational contexts and to present an overview of advances to date. We conducted a systematic literature review in Medline and PsycINFO using a comprehensive list of relevant search terms (2000–2018) to identify studies on multi-cultural BPPIs within organisational contexts. Findings provide support for the short-term effectiveness of various types of BPPIs in multi-cultural organisational contexts, however, the statistical power and long-term effects of these studies are questionable. Specifically, it seems that workplace mindfulness-based training, (web-based and multi-modal) stress management, and acceptance and commitment therapy mitigate consequences like stress and burnout, though more evidence is needed to support that BBPIs actively promote positive psychological outcomes. This chapter presents an overview of advances made to-date and aims to encourage researchers to consider multi-cultural aspects when developing BPPI interventions.\u3cbr/\u3e\u3cbr/\u3eKeywords\u3cbr/\u3eBrief positive psychological interventions Multi-cultural contexts Intervention research Systematic literature revie
