Evaluation of an mHealth Medication Regimen Self-Management Program for African American and Hispanic Uncontrolled Hypertensives.

African Americans and Hispanics have disproportionate rates of uncontrolled essential hypertension (EH) compared to Non-Hispanic Whites. Medication non-adherence (MNA) is the leading modifiable behavior to improved blood pressure (BP) control. The Smartphone Medication Adherence Stops Hypertension (SMASH) program was developed using a patient-centered, theory-guided, iterative design process.

[Percutaneous treatment under echographic guidance of toxic thyroid nodules. Technique for its performance and preliminary results].

Six patients affected by toxic thyroid nodules (Plummer disease) were treated by percutaneous ethanol injection (PEI). Treatment was performed injecting under ultrasound guidance 2-4 mL of 95% sterile ethyl alcohol through a spinal needle (22 gauge, 75 mm length). Treatment was performed once-twice weekly and repeated as an outpatient procedure 4-6 times.

Quantitative evaluation of spleen haemodynamics from radiocolloidal dynamic scintigraphy.

Quantitative information on spleen perfusion may be obtained as a byproduct of liver studies using 99Tcm colloids, by means of model analysis of dynamic data collected with a large field-of-view computerized gamma camera for about 4 min after intravenous administration of the tracer. Spleen extraction efficiency, vascular transit time, and parameters related to spleen blood flow, splenic clearance and volume of distribution of the tracer were computed, the latter three being expressed in arbitrary units. Results in 14 normal subjects and 78 patients with liver cirrhosis show good agreement with known physiopathological data.

A new approach to non-invasive quantitative study of hepatic haemodynamics using radiocolloids in vivo.

A non-invasive radioisotopic method for the study of liver haemodynamics is described. Data collected by means of a computerised gamma camera for about 4 min after intravenous administration of 99Tcm human serum albumin colloids were analysed using a new mathematical model formulated on a physiopathological basis. Several quantities of possible clinical interest were determined, namely parameters related to liver blood flows, intrahepatic shunts, the intrahepatic space of distribution of the tracer, transit times and extraction efficiency.
