Tests for Serum Transglutaminase and Endomysial Antibodies Do Not Detect Most Patients With Celiac Disease and Persistent Villous Atrophy on Gluten-free Diets: a Meta-analysis.

Background & Aims: Tests to measure serum endomysial antibodies (EMA) and antibodies to tissue transglutaminase (tTG) were developed to screen for celiac disease in patients consuming gluten. However, they are commonly used to monitor patients on a gluten-free diet (GFD). We conducted a meta-analysis to assess the sensitivity and specificity of tTG IgA and EMA IgA assays in identifying patients with celiac disease who have persistent villous atrophy despite a GFD.

The impact of frailty on outcomes after cardiac surgery: a systematic review.

Objective: Current preoperative assessments for cardiac surgery, such as the European System for Cardiac Operative Risk Evaluation II and the Society of Thoracic Surgeons risk score, are limited in their ability to predict postoperative outcomes. This is thought to be due to the reliance on chronological age as a predictor of health. In geriatrics, frailty assessments have been developed as a tool in determining physiologic functioning capacity.

What your patient reads: creating a value-added tool for physicians.

Through a number of media sources, today's consumers have unprecedented access to health information of varying reliability and authority. Empowered by this information, patients are more involved in their health care decisions and more willing to question physicians' advice. This poses a challenge for physicians who must now find time to read mass media health reports in addition to medical research.
