Patients undergoing weight loss surgery have high rates of H pylori bacteria

19.10.2004


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.



Before surgery, 24 percent of the patients tested positive for the H pylori infection. Of those who tested positive for H pylori, 48 percent showed significant upper gastrointestinal tract symptoms indicative of H pylori infection after surgery, while similar symptoms were present in 19 percent of the H pylori-negative group. Those with prolonged symptoms who tested positive for the infection were given treatment to eliminate the infection.

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...

Im Focus: Wafer-thin Magnetic Materials Developed for Future Quantum Technologies

Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.

Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...

Im Focus: Using graphene to create quantum bits

In the race to produce a quantum computer, a number of projects are seeking a way to create quantum bits -- or qubits -- that are stable, meaning they are not much affected by changes in their environment. This normally needs highly nonlinear non-dissipative elements capable of functioning at very low temperatures.

In pursuit of this goal, researchers at EPFL's Laboratory of Photonics and Quantum Measurements LPQM (STI/SB), have investigated a nonlinear graphene-based...
