Urbanisation historique du littoral caribéen : Saint-Pierre et La Havane
Depuis les premiers temps de la conquĂȘte europĂ©enne du Nouveau monde, lâinstallation de tĂȘtes de pont destinĂ©es au fonctionnement du systĂšme colonial et Ă la connexion avec les mĂ©tropoles a toujours constituĂ© un enjeu de premiĂšre importance. Aux nĂ©cessitĂ©s habituelles de proximitĂ© de terres cultivables, de bois de chauffage, de rĂ©serves dâeau potable, etc., qui Ă©taient dĂ©jĂ dĂ©terminantes pour la fondation des villages amĂ©rindiens, sâajoutait, pour les europĂ©ens, le problĂšme du mouillage des b..
NĂ©olithisation du Bassin CaribĂ©en : lâarchipel antillais
Les modalitĂ©s de transition entre Ă©conomies de prĂ©dation et de production ont Ă©tĂ© fort peu Ă©tudiĂ©es, dans la CaraĂŻbe insulaire. Ces phĂ©nomĂšnes sây sont dĂ©veloppĂ©s de maniĂšre rĂ©cente, vers 300 av. J.-C., sur la base de connaissances technologiques apportĂ©es du continent sud-amĂ©ricain par des populations qui les pratiquaient dĂ©jĂ depuis plus de trois millĂ©naires. Le programme que nous avons consacrĂ© Ă cet aspect de lâhistoire prĂ©colombienne de lâarchipel antillais a comme principaux points dâan..

COVID-19 symptoms at hospital admission vary with age and sex: results from the ISARIC prospective multinational observational study
Background:
The ISARIC prospective multinational observational study is the largest cohort of hospitalized patients with COVID-19. We present relationships of age, sex, and nationality to presenting symptoms.
Methods:
International, prospective observational study of 60â109 hospitalized symptomatic patients with laboratory-confirmed COVID-19 recruited from 43 countries between 30 January and 3 August 2020. Logistic regression was performed to evaluate relationships of age and sex to published COVID-19 case definitions and the most commonly reported symptoms.
Results:
âTypicalâ symptoms of fever (69%), cough (68%) and shortness of breath (66%) were the most commonly reported. 92% of patients experienced at least one of these. Prevalence of typical symptoms was greatest in 30- to 60-year-olds (respectively 80, 79, 69%; at least one 95%). They were reported less frequently in children (â€â18 years: 69, 48, 23; 85%), older adults (â„â70 years: 61, 62, 65; 90%), and women (66, 66, 64; 90%; vs. men 71, 70, 67; 93%, each Pâ<â0.001). The most common atypical presentations under 60 years of age were nausea and vomiting and abdominal pain, and over 60 years was confusion. Regression models showed significant differences in symptoms with sex, age and country.
Interpretation:
This international collaboration has allowed us to report reliable symptom data from the largest cohort of patients admitted to hospital with COVID-19. Adults over 60 and children admitted to hospital with COVID-19 are less likely to present with typical symptoms. Nausea and vomiting are common atypical presentations under 30 years. Confusion is a frequent atypical presentation of COVID-19 in adults over 60 years. Women are less likely to experience typical symptoms than men
