Mathematical images in advertising: constructing difference and shaping identity, in global consumer culture

Mathematics educators have long emphasised the importance of attitudes and feelings towards mathematics, as crucial in motivating (or not) its learning and use, and as influenced in turn by its social images. This paper is about images of mathematics. Our search for advertisements containing such images of in UK daily newspapers, during 2006-2008, found that 4.7% of editions included a ‘mathematical’ advert, compared with 1.7% in pilot work for 1994-2003. The incidence varied across type of newspaper, being correlated with class and gender profiles of the readership. Three-quarters of advertisements were classified as containing only very simple mathematics. ‘Semiotic-discursive’ analysis of selected advertisements suggests that they draw on mathematics not to inform, but to connote qualities like precision, certainty and authority. We discuss the discourse on mathematics in advertising as ‘quasi-pedagogic’ discourse, and argue that its oversimplified forms, being empty of mathematical content, become powerful means for regulating and ‘pedagogising’ today’s global consumers

Two cases of multi-inflammatory syndrome in children (MIS-C) in adults in 2020

Abstract Background Late complications and longer-lasting sequelae of COVID-19 infection in adults can occur. Cardiovascular involvement including reduced ejection fraction, coronary artery aneurysms, and pericardial involvement have been reported. Prompt recognition is the first step and secondly, these cardiovascular phenomena require an alternative set of therapeutics from the standard of care for acute COVID-19 infection. Case presentation Here we describe two cases that fulfill the current case definition of the recently defined multisystem inflammatory syndrome in adults (MIS-A). One patient is a 27-year-old white female and the other a 21-year-old French creole male, both without any prior medical history. Both were hospitalized and found to have significant cardiac dysfunction and treated with IVIG, high dose aspirin, and corticosteroids with resolution of their acute illnesses and cardiac sequelae. Conclusion Not only does the immediate impact of this viral infection need to be addressed, but also the long-term complications that could arise if not recognized and treated promptly as seen in our two cases. Patients can develop acute cardiovascular collapse and cardiogenic shock which requires high level of care and treatment within an intensive care unit. Depending on the complications, patients may require treatment for congestive heart failure, pericarditis, or even coronary artery disease acutely with close follow up to ensure improvement or resolution. </jats:sec

Short-course R-CHOP followed by 90Y-Ibritumomab tiuxetan in previously untreated high-risk elderly diffuse large B-cell lymphoma patients: 7-year long-term results

An update at 7 years was conceived for our multicenter phase II study in which 55 elderly high-risk untreated diffuse large B-cell lymphoma patients were treated with (90)Y-ibritumomab tiuxetan after a short course of rituximab, cyclophosphamide, doxorubicin, vincristine and prednisolone (R-CHOP) as long-term follow-up analyses of this combined therapeutic modality are lacking. The overall response rate to the entire regimen was 80%, including 73% (40/55) of complete response (CR) rate and 7% (4/55) of partial response rate. At the time of writing, 24/55 (43.6%) patients experienced a progression disease and 20 of 40 (50%) patients who obtained a CR are still alive in continuous CR. With a median follow-up of 7 years, the disease-free survival was 43.3% and the progression-free survival was 36.1%. The overall survival at 7.9 years was 38.9% (27 deaths mainly because of lymphoma). Two patients developed secondary hematological malignancies, an acute myeloid leukemia and a myelodysplastic syndrome, at 4 and 3 years from radioimmunotherapy, respectively. Our data confirm the feasibility, efficacy and safety of four cycles of R-CHOP followed by radioimmunotherapy consolidation even in the long term: this combination allows dispensing less chemotherapy in a frail group of patients without invalidating response quality and duration
