Quantification of gastric mucosal microcirculation as a surrogate marker of portal hypertension by spatially resolved subdiffuse reflectance spectroscopy in diagnosis of cirrhosis: a proof-of-concept study.

Background And Aims: Portal pressure can be used to identify patients with chronic liver disease who have progressed to cirrhosis. Portal pressure can also provide accurate prognostication for patients with cirrhosis. However, there are no practical means for assessment of portal pressure.

Mammographic Breast Density Assessed with Fully Automated Method and its Risk for Breast Cancer.

Objectives: We evaluated the association between breast cancer and breast density (BD) measured using fully automated software. We also evaluated the performance of cancer risk models such as only clinical risk factors, density related measures, and both clinical risk factors and density-related measures for determining cancer risk.

Materials And Methods: This is a retrospective case-control study.

QuantiFERON-TB Gold In-Tube reliability for immigrants with parasitic infections in Boston, USA.

Accurate testing and treatment for latent tuberculous infection is necessary for tuberculosis elimination. Certain parasite infections are associated with increased tuberculin skin test positivity; species-specific effects on QuantiFERON-TB Gold In-Tube (QGIT) have not been described. To determine whether infection with helminths or protozoa affects QGIT results.

Ferritin and increased vs upper reference interval tibc saturation to identify increased iron stores in African Americans.

Background: Increased serum ferritin (SF) in combination with increased total iron binding capacity saturation (TS) in the upper reference internal was evaluated to identify African Americans with increased iron stores.

Methods: Among 16,856 primary care-based African Americans screened at Howard University Field Center of the Hereditary Hemochromatosis and Iron Overload Screening (HEIRS) Study, 142 with SF >500 microg/l women or >700 microg/l men and increased TS (>45% women or >50% men; main study) and 146 with similar ferritin increases and upper reference interval TS (30-45% women or 35-50% men; ancillary study) were offered clinical evaluation to confirm increased SF and identify the cause.

Results: Repeat SF remained increased in 83% of 92 participants with increased TS initially (main study) vs 58% of 64 with upper reference interval TS initially (ancillary study) (P=0.

Case of chronic eosinophilic leukemia with deletion of chromosome 16 and hepatitis C.

Chronic eosinophilic leukemia is a rare entity, characterized by eosinophilia of >1.5 x 10(9)/L, persisting for >6 months after exclusion of other reactive and neoplastic causes of eosinophilia, and occurring in association with a clonal cytogenetic abnormality. Various chromosomal abnormalities have been associated with chronic eosinophilic leukemia.
