UCLA Uses Hybrid, Precision Heart Procedures to Help Stop Deadly Arrhythmias

New techniques now being used at UCLA allow doctors to more precisely target certain areas of the heart to stop ventricular arrhythmias — serious abnormal rhythms in the heart’s lower chambers — in high-risk patients.

Generally, arrhythmias can be controlled by medications, and sometimes defibrillators. But a potentially life-threatening, recurrent arrhythmia known as a ventricular tachycardia, which originates in one of the heart’s two ventricles, can produce a fast heart beat that requires other interventions, such as catheter ablation, in which the precise focus area of the arrhythmia must be controlled.

Cardiologists will often use catheter ablation once medications and other therapies have failed. The procedure involves the insertion of a tiny, metal-tipped catheter through a vein in the groin or neck to reach the inside of the heart. Prior to the procedure, electrical tests are conducted on the heart to identify and map the exact site of the arrhythmia’s origin. (more…)

IBM Pledges $50 Million To Create 100 Smarter Cities

ARMONK, N.Y. – 09 Nov 2010: IBM today inaugurated Smarter Cities Challenge, a competitive grant program in which IBM will award $50 million worth of technology and services to help 100 municipalities across the globe. Teams of IBM experts will provide city leaders with recommendations for successful growth, better delivery of municipal services, more citizen engagement, and improved efficiency.

This new program is the single-largest philanthropic investment currently planned by IBM, which made US$186 million worth of charitable contributions in 2009, comprising cash, technology, and consulting services. (more…)

This Black-capped Chickadee, captured in Anchorage, Alaska, demonstrates an overgrown beak characteristic of avian keratin disorder. Beak deformities in this species were first observed in the late 1990s and biologists have since documented more than 2,100 affected individuals in Alaska. Image credit: U.S. Geological Survey

ANCHORAGE, Alaska – The highest rate of beak abnormalities ever recorded in wild bird populations is being seen in a number of species in the Northwest and Alaska, and scientists to this point have not been able to isolate the cause.

Black-capped Chickadees, Northwestern Crows, and other birds are being impacted by the problem, which affects their ability to feed and clean themselves and could signal a growing environmental health problem.

In birds affected by what scientists have termed “avian keratin disorder,” the keratin layer of the beak becomes overgrown, resulting in noticeably elongated and often crossed beaks, sometimes accompanied by abnormal skin, legs, feet, claws and feathers. Biologists with the U.S. Geological Survey’s Alaska Science Center published their findings in this month’s issue of The Auk, a Quarterly Journal of Ornithology.

“The prevalence of these strange deformities is more than ten times what is normally expected in a wild bird population,” said research biologist Colleen Handel with the USGS, “We have seen effects not only on the birds’ survival rates, but also on their ability to reproduce and raise young. We are particularly concerned because we have not yet been able to determine the cause, despite testing for the most likely culprits.” (more…)

Low Blood Levels of Vitamin D Linked to Chubbier Kids, Faster Weight Gain

ANN ARBOR, Mich.—Kids who are deficient in vitamin D accumulated fat around the waist and gained weight more rapidly than kids who got enough vitamin D, a new University of Michigan study suggests.

Vitamin D, which is primarily provided to the body by the sun, has been a hot topic in the U.S. lately. The federal standards for vitamin D intake have come under fire by public health professionals as being much too low, and disagreement continues over the proper amount of vitamin D necessary for optimal health.

Windows Phone 7 Takes Aim at Bad Phone Design

*Windows Phone 7 goes on sale today at AT&T and T-Mobile stores throughout the United States. The phone takes a new approach to smartphone design, hopefully addressing some of the “Bad Mobile Phone Behavior” called out in a new survey released today.*

REDMOND, Wash. – Nov. 8, 2010 – The mobile phone, like the craftiest of invasive species, knows no boundaries. It has crept into every inch of our lives, and spotting one in the bathroom or the bedroom can only elicit a weary response: “Really?”

According to a new survey released today, the answer across the country is a resounding – if resigned – “Yes.” (more…)

Fast Food Restaurants Dish Up Unhealthy Marketing to Youth

Children as young as age 2 are seeing more fast food ads than ever before, and restaurants rarely offer parents the healthy kids’ meal choices, according to a new study from Yale’s Rudd Center for Food Policy & Obesity. The new evaluation, the most comprehensive study of fast food nutrition and marketing ever conducted, shows that fast food marketers target children across a variety of media and in restaurants. In addition, the study finds that restaurants provide largely unhealthy defaults for the side dishes and drinks that come with kids’ meals. The detailed findings of this study will be presented in Denver today during the American Public Health Association’s annual meeting. (more…)
