Plasma metabolomic profile in chronic thromboembolic pulmonary hypertension.

We aimed to characterize the plasma metabolome of chronic thromboembolic pulmonary hypertension patients using a high-throughput unbiased omics approach. We collected fasting plasma from a peripheral vein in 33 operable chronic thromboembolic pulmonary hypertension patients, 31 healthy controls, and 21 idiopathic pulmonary arterial hypertension patients matched for age, gender, and body mass index. Metabolomic analysis was performed using an untargeted approach (Metabolon Inc.

Pulmonary embolism response teams.

Pulmonary embolism (PE) is a common thrombotic event that is variable in its presentation. Depending on the patients' risk for mortality, guidelines provide several treatment strategies including thrombolysis, catheter-directed therapies, pulmonary embolectomy, anticoagulation, and inferior vena cava filters. However, there is considerable disagreement between guidelines regarding the optimal treatment strategy for patients, particularly for those with intermediate-risk PE.

Metabolite quantification and high-field MRS in breast cancer.

In vivo 1H MRS is rapidly developing as a clinical tool for diagnosing and characterizing breast cancers. Many in vivo and in vitro experiments have demonstrated that alterations in concentrations of choline-containing metabolites are associated with malignant transformation. In recent years, considerable efforts have been made to evaluate the role of 1H MRS measurements of total choline-containing compounds in the management of patients with breast cancer.
