    Surgery 2016 Dec 15. Epub 2016 Dec 15.
    Section of Endocrine Surgery, Department of Surgery, University of Wisconsin, Madison, WI. Electronic address:
    Background: Parathyroidectomy offers the only cure for primary hyperparathyroidism, but today only 50% of primary hyperparathyroidism patients are referred for operation, in large part, because the condition is widely under-recognized. The diagnosis of primary hyperparathyroidism can be especially challenging with mild biochemical indices. Machine learning is a collection of methods in which computers build predictive algorithms based on labeled examples. Read More

    Arq Bras Cardiol 2016 Nov;107(5):467-481
    Instituto Estadual de Cardiologia Aloysio de Castro (IECAC), Rio de Janeiro, RJ - Brazil.
    Cardiopulmonary exercise test (CPET) has been gaining importance as a method of functional assessment in Brazil and worldwide. In its most frequent applications, CPET consists in applying a gradually increasing intensity exercise until exhaustion or until the appearance of limiting symptoms and/or signs. The following parameters are measured: ventilation; oxygen consumption (VO2); carbon dioxide production (VCO2); and the other variables of conventional exercise testing. Read More
