Perils of Reduced Dose Apixaban In Atrial Fibrillation/Flutter - A Case Report with a Brief Literature Review.
Patients with atrial fibrillation/atrial flutter (AF) are notoriously predisposed to thromboembolic events secondary to the development of thrombi within the left atrium of the heart. AF accompanied by a fairly decent CHA2DS2-VASc score is a known indication for full anticoagulation, frequently with direct oral anticoagulants (DOACs), such as apixaban. ⋯ However, with rising concern for bleeding complications, many physicians are found to have been reducing the dose of apixaban despite the patient not completely meeting the defined criteria. Our study particularly emphasizes the risk of significantly increased thromboembolic complications in the setting of sub-therapeutic anticoagulation, in patients with both appropriately and inappropriately reduced doses of apixaban.

Review
Metformin as adjuvant treatment in hepatitis C virus infections and associated complications.
Hepatitis C virus is an important global cause of hepatitis and subsequently cirrhosis and hepatocellular carcinoma. These infections may also cause extrahepatic manifestations, including insulin resistance and type 2 diabetes mellitus. These two complications can potentially reduce sustained virologic responses (SVR) in some drug regimens for this infection. ⋯ Metformin also reduces the frequency of hepatocellular carcinoma in patients who have had SVRs. Larger treatment trials are needed to determine metformin's short-term and long-term treatment effects in patients with diabetes using newer antiviral drugs. In particular, if metformin reduces the frequency of cirrhosis and hepatocellular carcinoma, this would significantly reduce the morbidity and mortality associated with this infection.
