von Willebrand disease (VWD), the most common inherited bleeding disorder, results when patients either do not make enough von Willebrand factor (VWF) or make defective VWF. The pathophysiology of this disorder is complex but needs to be understood to interpret the diagnostic tests. Most patients have mild to moderate symptoms and can be adequately counseled and managed by a general internist, but some need to consult a hematologist. We review the pathophysiology of VWD, its subtypes, common presentations of each subtype, diagnostic testing, and management of mild as well as severe clinical manifestations of VWD.

Although most pancreatic cystic lesions do not progress to cancer, they create concern for patients and their primary care physicians. The lack of consensus guidelines on diagnosis and surveillance of these lesions can lead to a management conundrum. We review current guidelines on diagnosis and management.

Venous thromboembolism (VTE) is a major health burden in patients with cancer, causing morbidity, emergency room visits, hospitalizations, and death. Treatment is challenging, as it is necessary to balance the risk of recurrent thrombosis and bleeding associated with anticoagulants. ⋯ Multiple recent randomized controlled trials have demonstrated the safety and efficacy of direct oral anticoagulants in this setting. Current studies are evaluating factor XI inhibitors as potential treatments for cancer-associated VTE.

Gastric intestinal metaplasia (GIM), a common histologic finding, is associated with increased risk of gastric cancer, and GIM associated with Helicobacter pylori infection is classified as an environmental metaplastic atrophic gastritis. Patients may be asymptomatic or present with various dyspeptic symptoms. Autoimmune metaplastic atrophic gastritis is a less common but important cause of chronic gastritis. ⋯ The risk of progression to malignancy is higher with incomplete GIM. It is also higher for those who immigrate from regions with a high incidence of H pylori infection to areas where the incidence is low. Guidelines regarding endoscopic management of GIM vary by geographic region.

Nonstatin therapy to reduce low-density lipoprotein cholesterol and improve cardiovascular outcomes.
Atherosclerotic cardiovascular disease (ASCVD) is a leading cause of morbidity and mortality, with low-density lipoprotein (LDL) cholesterol being a causative risk factor. Though statins have a decades-long track record of efficacy and safety, nonstatin agents may be used to reduce LDL cholesterol as an adjunct or alternative to statin therapy. Several new nonstatin medications have been approved in recent years, with robust data from clinical trials supporting their use in atherosclerotic disease. This review addresses the indications, evidence, and important prescribing considerations for using nonstatin lipid-lowering therapy and proposes a practical approach for determining when to initiate nonstatin therapy.
