Iron deficiency following bariatric surgery: a retrospective cohort study.

Iron deficiency is a common consequence of bariatric surgery and frequently leads to anemia. Our study reports the incidence and predictors of iron deficiency, iron deficiency anemia (IDA), and IV iron use after bariatric surgery. We conducted a retrospective study of all adult patients who underwent bariatric surgery from January to December 2012 at the regional bariatric surgery center in Hamilton, Ontario, Canada, and were followed for at least 6 months.

Erythropoiesis-stimulating agents in elderly patients with anemia: response and cardiovascular outcomes.

A specific cause of anemia cannot be identified in many elderly patients. Erythropoiesis-stimulating agents (ESAs) may play a role in treating these patients with anemia of unknown etiology (AUE). This study examines hemoglobin and cardiovascular outcomes among elderly anemic patients treated with ESAs.

Erythropoietin Levels in Elderly Patients with Anemia of Unknown Etiology.

Background: In many elderly patients with anemia, a specific cause cannot be identified. This study investigates whether erythropoietin levels are inappropriately low in these cases of "anemia of unknown etiology" and whether this trend persists after accounting for confounders.

Methods: This study includes all anemic patients over 60 years old who had erythropoietin measured between 2005 and 2013 at a single center.
