Timeliness of childhood vaccinations in the Philippines.

Timeliness of vaccinations is rarely part of monitoring in a routine immunization program. We reviewed infant immunization and conducted caregiver interviews in three regions in the Philippines from January to October 2016. We randomly selected thirty public health centers, one for each region.

Loss of contrast intensity during systole in the left ventricular cavity with the use of the contrast agent Albunex. An analysis of its correlation with pressure and velocity.

Rationale And Objectives: Several investigators have observed a decrease in video intensity in the left ventricular cavity during systole when using contrast echocardiography. It has been suggested that this phenomenon is related to microbubble instability. The authors propose that this phenomenon is, in part, related to the effects of pressure and velocity on the acoustic reflectance of ultrasound contrast agents.
