Pharmacotherapy prevention and management of nutritional deficiencies post Roux-en-Y gastric bypass.

Roux-en-Y gastric bypass is the most commonly performed bariatric procedure. It is associated with nutritional deficiencies due to gastric reduction, intestinal bypass, reduced caloric intake, avoidance of nutrient-rich foods, noncompliance with supplementation and poor food tolerability. Although there are multiple publications on this topic, there is a lack of consistent guidance for the healthcare practitioner caring for the bariatric patient.

Efficacy and safety of novel anticoagulants compared with established agents.

Dabigatran, rivaroxaban, and apixaban are novel oral anticoagulants that offer major advantages over existing agents. The onset of the anticoagulant effect of these agents is rapid. Each agent has a predictable anticoagulant response that eliminates the need for monitoring.

Use of digoxin for heart failure and atrial fibrillation in elderly patients.

Background: Digoxin has been reported to improve symptoms and reduce hospitalization in patients with heart failure as well as to control rapid ventricular rate in patients with atrial fibrillation. Both of these are high-prevalence diseases in the elderly, and yet studies have indicated that digoxin may not be used appropriately in this population. Clinical trials evaluating digoxin use specifically in the elderly are scarce.
