El mundo hispánico durante el Antiguo Régimen desde los circuitos mercantiles y el espacio económico rioplatense

Since the 1980’s, the questioning of the national paradigm and, to a lesser extent, of the colonial one, has led to a renewal of modern studies of the Spanish monarchy. This article discusses the emerging body of academic literature about mercantile circulation, highlighting that there is still a need to reshape the relevant units of analysis. Based on the spatial economy, it sets forth a hypothesis about the markets which might have formed the Hispanic world and its dynamics. It also synthesizes the foundations and advances of the “River Plate economic space” (espacio económico rioplatense), polarized in the direction of the region of the Río de la Plata. Our hypothesis seeks to explain the historic foundations of the establishment of the internal market of the Republic of Argentina

Diagnosis and management of asymptomatic bacteriuria in kidney transplant recipients: a survey of current practice in Europe

International audienceBackgroundAsymptomatic bacteriuria is frequent in kidney transplant recipients (KTRs). However, there is no consensus on diagnosis or management. We conducted a European survey to explore current practice related to the diagnosis and management of asymptomatic bacteriuria in adult KTRs.MethodsA panel of experts from the European Renal Association–European Dialysis Transplant Association/Developing Education Science and Care for Renal Transplantation in European States working group and the European Study Group for Infections in Compromised Hosts of the European Society of Clinical Microbiology and Infectious Diseases designed this cross-sectional, questionnaire-based, self-administered survey. Invitations to participate were e-mailed to European physicians involved in the care of KTRs.ResultsTwo hundred and forty-four participants from 138 institutions in 25 countries answered the survey (response rate 30%). Most participants [72% (176/244)] said they always screen for asymptomatic bacteriuria in KTRs. Six per cent (15/240) reported never treating asymptomatic bacteriuria with antibiotics. When antimicrobial treatment was used, 24% of the participants (53/224) said they would start with empirical antibiotics. For an episode of asymptomatic bacteriuria caused by a fully susceptible microorganism and despite no contraindications, a majority of participants (121/223) said they would use a fluoroquinolone (n = 56), amoxicillin/clavulanic acid (n = 38) or oral cephalosporins (n = 27).ConclusionsScreening for and treating asymptomatic bacteriuria are common in KTRs despite uncertainties around the benefits and harms. In an era of antimicrobial resistance, further studies are needed to address the diagnosis and management of asymptomatic bacteriuria in these patients
