IMPORTANCE No consensus exists regarding the definition of high-risk surgery in older adults. An inclusive and precise definition of high-risk surgery may be useful for surgeons, patients, researchers, and hospitals. OBJECTIVE To develop a list of high-risk operations. DESIGN, SETTING, AND PARTICIPANTS Retrospective cohort study and modified Delphi procedure. The setting included all Pennsy...

The overall goal of MENELAS is to provide better access to the information contained in natural language patient discharge summaries, through the design and implementation of a pilot system able to access medical reports through natural languages. A first, experimental version of the MENELAS indexing prototype for French has been assembled. Its function is to encode free text PDSs into both an ...

We obtain a polynomial type upper bound for the size of the integral solutions of Thue equations F (X,Y ) = b defined over a totally real number field K, assuming that F (X, 1) has a root α such that K(α) is a CM-field. Furthermore, we give an algorithm for the computation of the integral solutions of such an equation.

We compare observations of the eclipsing binary system CM Draconis (hereafter CM Dra) with synthetic spectra computed using the stellar atmosphere code PHOENIX. High-resolution infrared spectroscopic observations of six 0.05-mm-wide regions between 1.51 and 2.45mm, combined with previous work, particularly CM Dra’s accurately known surface gravity, enable us to estimate its metallicity using de...
