Association Between Patient and Physician Sex and Physician-Estimated Stroke and Bleeding Risks in Atrial Fibrillation

Background

Physicians treating nonvalvular atrial fibrillation (AF) assess stroke and bleeding risks when deciding on anticoagulation. The agreement between empirical and physician-estimated risks is unclear. Furthermore, the association between patient and physician sex and anticoagulation decision-making is uncertain.

Fungal endocarditis — a report on seven cases and a brief review

Summary Candida endocarditis is an unusual but severe complication of systemic infection caused byCandida albicans and occasionally by other fungal species. We describe seven cases that occurred during a period of 20 years in western Sweden. In four cases infections were located on prosthetic valves and in three cases native valves were involved. Three patients died of the disease in the acute phase. A definite diagnosis was established in one of four survivors. This patient had an aortic valve endocarditis and a saddle embolisation and was treated with immediate surgery, followed by intensive treatment with liposomal amphotericin B + flucytosine. Fungal endocarditis is still a serious disease with a high mortality and whenever the diagnosis is suspected, antifungal therapy must be started and transesophageal sonography should be performed to visualize vegetations. Immediate surgery should be considered.

Pilzendokarditis — Bericht über sieben Fälle und kurze Literaturübersicht

Zusammenfassung DieCandida-Endokarditis ist eine seltene, aber schwere Komplikation einer systemischen Infektion durchCandida albicans und gelegentlich auch durch andere Pilzspezies. Wir berichten über sieben Fälle, die in einem Zeitraum von 20 Jahren in Westschweden beobachtet wurden. In vier Fällen waren Klappenprothesen und in drei Fällen natürliche Klappen betroffen. Drei Patienten starben in der akuten Phase an der Krankheit. Bei einem der vier überlebenden Patienten konnte die Diagnose eindeutig gesichert werden. Dieser Patient hatte eine Aortenklappenendokarditis und einen reitenden Embolus. Er wurde sofort operiert und hochdosiert mit liposomalem Amphotericin B und mit Flucytosin behandelt. Die Pilzendokarditis ist nach wie vor eine ernste, mit hoher Letalität belastete Krankheit. Die antimykotische Therapie muß bereits beim ersten Verdacht begonnen werden. Um Vegetationen nachzuweisen, sollte die transösophageale Sonographie durchgeführt werden. Ein sofortiges chirurgisches Eingreifen ist zu erwägen.

     

Chemical composition of a new variety of the Andean lupin (Lupinus mutabilis cv. Inti) with low-alkaloid content

The chemical composition of the seeds of the low-alkaloid variety “Inti” of the Andean lupin (Lupinus mutabilis) grown in the south of Chile was examined. The contents of (% of dry weight) total alkaloids, protein, lipids, and oligosaccharides were found to be 0.0075, 51.0, 16.0, and 14.7%, respectively. The low levels of the sulfur amino acids (2.38% of total protein) made them the first amino acids to limit the protein quality of these lupin seeds. The fatty acid pattern was C16:0,13.9%; C18:0, 3.0%; C18:1, 41.8%; C18:2, 38.9%; and C18:3,2.6% of total fatty acids. The α-galactoside amounted to 13.5% of dry weight (raffinose, 2.49%; stachyose, 10.1%, verbascose, 0.85%). It can be stated that “Inti” is highly interesting as a potential protein energy crop for a temperate climate.
