Echocardiography reporting of pulmonary hypertension and subsequent referral to a specialty clinic.

Introduction: Echocardiography is commonly performed in the evaluation of patients with pulmonary hypertension (PH). The report summary often serves to guide the future evaluation of these patients. Our aim was to explore the relationship between the echocardiography reports of patients with PH and referral to a PH specialty clinic.

Relation of Venous Thromboembolism Risk to Ischemic Stroke Risk in Hospitalized Patients with Cancer.

Patients with cancer are at increased risk for venous thromboembolism (VTE). However, the relationship of cancer type to the risk of arterial thrombosis in patients with high VTE risk has not been described. The goal of this study is to determine the rate of arterial thrombosis in patients with different types of solid tumors stratified by VTE risk.

Development of associations between microalgae and denitrifying bacteria in streams of contrasting anthropogenic influence.

We compared the development of microalgal and bacterial-denitrifier communities within biofilms over 28 days in a restored-prairie stream (RP) and a stream receiving treated wastewater effluent (DER). Inorganic nutrient concentrations were an order of magnitude greater in DER, and stream waters differed in the quality of dissolved organics (characterized via pyrolysis-GC/MS). Biofilm biomass and the densities of algae and bacteria increased over time in both systems; however, algal and denitrifier community composition and the patterns of development differed between systems.
