Disease Prevention Not Necessarily A Money Saver
The Associated Press reports on the costs of disease prevention: "When it comes to health care spending, an ounce of prevention is seldom worth a pound of cure. ...The truth is, shockingly few prevention efforts actually save the health care system money overall, despite claims by the president and some in Congress."

Reengineering A Food Poisoning Microbe To Carry Medicines And Vaccines
Scientists have used genetic engineering to tame one of the most deadly food poisoning microbes and turn it into a potential new way of giving patients medicine and vaccines in pills rather than injections. The study is in the current issue of ACS" Molecular Pharmaceutics, a bi-monthly journal.

Baseline Dopamine Levels And Our Motivation To Eat Influenced By Fat Hormone
As we all know from experience, people eat not only because they are hungry, but also because the food just simply tastes too good to pass up. Now, a new study in the August 6th Cell Metabolism, a Cell Press publication, helps to explain how leptin, a hormone produced by fat tissue, influences that motivation to eat.

St. Jude Medical Announces FDA Approval Of The Cool Point Irrigation Pump

St. Jude Medical, Inc. (NYSE:STJ) announced U.S. Food and Drug Administration (FDA) approval of its Cool Point™ Irrigation Pump. Used in conjunction with SJM open-irrigated ablation catheters, an irrigation pump supplies a continuous flow of saline through the catheter"s inner lumen to cool the ablation electrode for more effective energy delivery. Designed to enhance physicians" ability to perform successful atrial ablations, the new Cool Point irrigation pump was developed specifically for use with the company"s IBI-1500T9-CP cardiac ablation generator and family of Therapy™ Cool Path™ irrigated catheters. "The Cool Point pump is part of a fully integrated system that has been designed for easy set up and seamless operation with our latest cardiac ablation generator and our growing family of Therapy Cool Path open-irrigated catheters," said Jane J. Song, president of the St. Jude Medical Atrial Fibrillation Division. "By introducing the Cool Point Irrigation Pump, we provide plug-and-play connectivity with the lab"s existing St. Jude Medical equipment." In addition to the intuitive setup and operation, the Cool Point Irrigation Pump provides monitoring and safety features, which are designed to give physicians more control over therapy delivery. This interface enables physicians to monitor the total volume of irrigation solution delivered through an easy-to-read display. The pump"s proprietary tubing includes an in-line occlusion detector, which monitors flow pressure between the pump and the catheter tip, providing an alert if flow pressure increases substantially relative to the flow rate (an indication that irrigation ports on the catheter tip may be blocked and the tip cooling may not be effective). In addition, the pump has redundant bubble detectors, each designed to detect bubbles as small as two microliters. Bubbles in the bloodstream may lead to embolism or stroke. Catheter ablation therapy is used by physicians to restore a normal heart rhythm in patients with, typical atrial flutter. During cardiac ablation, an electrophysiologist (EP) uses a catheter (a thin, flexible tube) to deliver energy that creates lesions in specific areas of cardiac tissue. The lesions, or tiny scars, interrupt the abnormal electrical signals that contribute to erratic heart rhythms. St. Jude Medical
