Masterly inactivity: A forgotten precept

Masterly inactivity: A forgotten precept.

Management of asymptomatic aortic stenosis: masterly inactivity but cat-like observation.

In patients presenting with symptoms, the natural history of significant aortic stenosis is unfavourable and the prognosis is dramatically improved by valve replacement. 1-3 However, some patients remain entirely free from symptoms despite severe outflow obstruction. When these asymptomatic patients are discovered incidentally it is often assumed that their outcome will be improved by surgery. ...

A Precept - Driven Learning Algorithm

Machine learning is an attempt at devising mechanismsthat machines can use to learn, rather than being explicitlyprogrammed for, real-world applications. The goal oflearning systems is to generalize. Generalization is basedon the set of critical features the system has available.Training set learners typically extract critical featuresfrom a random set of examples drawn ...

The natural history of left ventricular thrombus in myocardial infarction: a rationale in support of masterly inactivity.

One hundred five unselected and consecutive patients were prospectively studies after acute transmural myocardial infarction to assess the incidence of mural thrombus formation and to relate the presence of thrombus to patient outcome in terms of systemic embolic events, functional class and survival. In 87 patients, optimal quality two-dimensional echocardiographic studies were obtained and we...

Sharka (Plum pox virus): A forgotten disease in Iran

Plum pox or sharka, a viral disease caused by Plum pox virus (PPV), severely affects the production of Prunus species in Europe. The first evidence of sharka was reported in Iran in 2000 . Due to the economic impact of this disease on crop production, recent advances in the term of  biology, epidemiology, and disease management are provided in this paper to assure awareness among growers and pr...
