Features of Mild-to-Moderate COVID-19 Patients with Dysphonia

Introduction To explore the prevalence of dysphonia in European patients with mild-to-moderate COVID-19 and the clinical features of dysphonic patients. Methods The clinical and epidemiological data of 702 patients with mild-to-moderate COVID-19 were collected from 19 European Hospitals. The following data were extracted: age, sex, ethnicity, tobacco consumption, comorbidities, general and otolaryngological symptoms. Dysphonia and otolaryngological symptoms were self-assessed through a 4-point scale. The prevalence of dysphonia, as part of the COVID-19 symptoms, was assessed. The outcomes were compared between dysphonic and non-dysphonic patients. The association between dysphonia severity and outcomes was studied through Bayesian analysis. Results A total of 188 patients were dysphonic, accounting for 26.8% of cases. Females developed more frequently dysphonia than males (p=0.022). The proportion of smokers was significantly higher in the dysphonic group (p=0.042). The prevalence of the following symptoms was higher in dysphonic patients compared with non-dysphonic patients: cough, chest pain, sticky sputum, arthralgia, diarrhea, headache, fatigue, nausea and vomiting. The severity of dyspnea, dysphagia, ear pain, face pain, throat pain and nasal obstruction was higher in dysphonic group compared with non-dysphonic group. There were significant associations between the severity of dysphonia, dysphagia and cough. Conclusion Dysphonia may be encountered in a quarter of patients with mild-to-moderate COVID-19 and should be considered as a symptom list of the infection. Dysphonic COVID-19 patients are more symptomatic than non-dysphonic individuals. Future studies are needed to investigate the relevance of dysphonia in the COVID-19 clinical presentation

Property relations by other means : conflict over dryland resources in Benin and Mali

Conflicts over natural resources and property concern the distribution of entitlements to resources and social identities. The highlighting of this continuity enables the insertion of conflict into a broader historical and theoretical framework dealing with social change, as well as access to and control over resources. However, this reveals nothing about the discontinuity between tensions over natural resources and outbreaks of conflict involving physical and symbolic violence. Case studies carried out in Mali and Benin provide an empirical basis for the discussion of the following set of exploratory hypotheses: they stress the continuity between conflict and property within the frame of a theory of access to natural resources; they emphasise the plurality of actors involved in disputes over natural resources in African drylands beyond the farmer-herdsman configuration; and they see resource conflict, property and policy as a matter of persuasion, that is, representation and narrative

The FELIN arithmetic coprocessor chip

ISBN: 0818607742International audienceA description is given of a general VLSI architecture for the computation of arithmetic expressions including floating-point transcendental functions. This architecture is divided in three parts: a communication machine, the control part of a computation machine, and the operative part of this computation machine. In order to compute the most usual transcendental functions, the authors introduce some general algorithms including, as a particular case, the CORDIC scheme. The major architecture goals were regularity, parameterization, and automatic design. The final chip is designed in a two-ALU CMOS technology, and its name is FELIN (fonctions elementaires integrees)
