Diagnosis, management and mortality in acute aortic syndrome: results of the Spanish Registry of Acute Aortic Syndrome (RESA-II).

Background: Recent advances in the diagnosis and treatment of acute aortic syndrome should improve the outcome of this disease. The Spanish Registry of Acute Aortic Syndrome aimed to assess current results in acute aortic syndrome management in a wide cohort of hospitals in the same geographical area.

Methods: From January 2012 to January 2014, 26 tertiary hospitals included 629 consecutive patients with acute aortic syndrome: 73% men, mean age 64.

Disseminated aspergillosis in an immunocompetent patient with detectable bis(methylthio)gliotoxin and negative galactomannan.

Background: Disseminated invasive aspergillosis is an exceptional finding in immunocompetent hosts. As in immunocompromised patients, it has high mortality rates. Early diagnostic methods are required in order to properly manage the patient.

Local root abscisic acid (ABA) accumulation depends on the spatial distribution of soil moisture in potato: implications for ABA signalling under heterogeneous soil drying.

Patterns of root abscisic acid (ABA) accumulation ([ABA]root), root water potential (Ψroot), and root water uptake (RWU), and their impact on xylem sap ABA concentration ([X-ABA]) were measured under vertical partial root-zone drying (VPRD, upper compartment dry, lower compartment wet) and horizontal partial root-zone drying (HPRD, two lateral compartments: one dry, the other wet) of potato (Solanum tuberosum L.). When water was withheld from the dry compartment for 0-10 d, RWU and Ψroot were similarly lower in the dry compartment when soil volumetric water content dropped below 0.

Two potato (Solanum tuberosum) varieties differ in drought tolerance due to differences in root growth at depth.

To test the hypothesis that root growth at depth is a key trait explaining some genotypic differences in drought tolerance in potato (Solanum tuberosum L.), two varieties (Horizon and Maris Piper) differing in drought tolerance were subjected to different irrigation regimes in pots in a glasshouse and in the field under a polytunnel. In the glasshouse, both cultivars showed similar gas exchange, leaf water potential, leaf xylem ABA concentration and shoot biomass independently of whether plants were grown under well watered or water deficit conditions.

Cerebral embolism and thrombus in a membranous interventricular septal aneurysm.

This report describes the occurrence of a thrombus in an aneurysm of the membranous interventricular septum with cerebral embolism in a young patient. We would recommend periodic echocardiography checkups in patients with aneurysm of the membranous interventricular septum with or without a small ventricular septal defect. The findings of a mass in the aneurysm, suggestive of thrombus, may justify anticoagulation treatment or even surgical intervention.
