Treatment breakthrough for rare disease linked to diabetes


University of Manchester scientists have led an international team to discover new treatments for a rare and potentially lethal childhood disease that is the clinical opposite of diabetes mellitus. Congenital hyperinsulinism (CHI) is a condition where the body's pancreas produces too much insulin – rather than too little as in diabetes – so understanding the disease has led to breakthroughs in diabetes treatment.
Current drug treatments for CHI often fail in the most severe forms of the disease and the patient has to have some, or most, of their pancreas removed. The Manchester researchers discovered that treating cells under specially modified conditions helped to recover the function of the internal switches that control insulin release. Through these experiments the team have provided the first evidence that the outcomes of gene defects can be reversed in human insulin-producing cells.

Developing robots for the hospital emergency room

When a patient arrives in the ER, the first thing he or she must do is register. Today, this is handled by a registration clerk. In the proposed system, the clerk would direct the patient (or attending family members) to a robot assistant in the form of a kiosk. The robot assistant would guide them through the registration process using a touch-screen and possibly voice prompts. When proper security measures are in place, the robot will be able to fill in much of the information for existing patients by accessing their electronic records. When the patients provide critical information, such as reporting chest pain, the robot can immediately alert the staff so they can provide immediate attention. Lacking such an alert, the robot would inform the patient of the current wait time and direct him or her to the waiting room.

The emergency room application is a perfect way to test a special cognitive architecture that the Vanderbilt engineers have developed for robots that is based on the working memory in the brain. "Our architecture is designed to allow robots to integrate quick decision-making with the more common deliberate decision-making process in flexible ways," Kawamura said.

The paper proposes a system of cognitive robots that gather medical information and take basic diagnostic measurements and ultimately provide tentative diagnoses to the human staff in order to address the critical concerns facing emergency departments in major hospitals: shortening the time that patients must wait, relieving the strain on overburdened emergency room staff and reducing the number of mistakes that are made.
