The prevalence of Helicobacter pylori (a type of bacteria associated with gastrointestinal disorders) is high among patients about to undergo weight loss surgery, and treatment to eradicate the bacterial infection before surgery may be beneficial, according to an article in the October issue of The Archives of Surgery, one of the JAMA/Archives journals.
The number of obese and morbidly obese Americans is steadily increasing, according to background information in the article. It is estimated that more than 30 percent of the U.S. population has a body mass index (BMI) over 30 (obese), and five percent of the U.S. population has a BMI over 40, resulting in a increased demand for weight loss surgery, including gastric bypass surgery (surgery that results in food bypassing much of the intestinal tract). Twenty to 50 percent of people living in industrialized countries are infected with H pylori, which is believed to be involved in gastroduodenal ulcer disease (a gastrointestinal tract disease characterized by ulcers in the stomach and upper intestinal tract, or foregut), in addition to gastric cancer, according to the article. The role of H pylori after gastric bypass surgery is unknown.
Archana Ramaswamy, M.D., from Emory University, School of Medicine, Atlanta, and colleagues examined 99 patients between September 2001 and September 2002 as part of an evaluation for weight loss surgery. The patients (16 men and 83 women; average age 40 years; average BMI, 48) underwent routine testing before their weight loss surgeries, including testing for the presence of H pylori.

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.
Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...
A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
