[Argentinean registry on the management of Helicobacter pylori infection: effectiveness and safety of first line treatment].

Introduction: The optimal management of Helicobacter pylori (H pylori) infection remains unclear. Updated information concerning local data is needed to design the best strategy to treat H. pylori infection to reach high eradication rates.

Relationship between obesity severity and Helicobacter pylori eradication in patients undergoing bariatric and metabolic surgery: A post hoc analysis.

Background: The global prevalence of obesity is increasing and represents a major public health challenge. However, there is a paucity of data regarding Helicobacter pylori (H pylori) eradication in people with obesity. The aim of the study is to examine the influence of obesity degree on H.

[Changes in the microbiota due to ultra-processed foods: obesity, cancer and premature death].

Ultra-processed foods (UPFs) are industrial formulations that are ubiquitous in every home and supermarket aisle. This food group includes snacks, soft drinks, ready-to-eat products like pizzas, nuggets, burger till commercial breads. Multiple long cohort studies have shown a relationship between their consumption and the rise in the incidence of obesity, type 2 diabetes, cardiovascular diseases, colorectal cancer and all-cause mortality.

Long-term follow-up after fetal radiation exposure during endoscopic retrograde cholangiopancreatography.

 The main concern about endoscopic retrograde cholangiopancreatography (ERCP) during pregnancy is the risk of radiation exposure to the fetus. The potential exists not only in the short-term, but also in the long-term and includes growth and development problems and the possibility of childhood cancer. Little is known about the long-term effects of fetal radiation exposure at the time of ERCP.

Tailored Helicobacter pylori eradication therapy in obese patients undergoing bariatric surgery.

Objectives: to compare the efficacy and safety of a tailored quadruple concomitant therapy based on body weight, with the same scheme but with fixed doses in obese patients undergoing bariatric surgery.

Methods: a prospective study was performed of 104 obese patients.

Results: the weight-based therapy group achieved significantly higher eradication rates in the intention-to-treat analysis; 86.

[Angiotensin II AT1 receptor antagonists as antiinflammatory and gastric protection drugs].

Background: The antiinflammatory and gastric cytoprotector effect of angiotensin II AT1 receptor antagonist, such as candesartan, losartan and valsartan was studied.

Material And Methods: Wistar rats were ramdomly assigned to receive: (1) 96 degrees ethanol; (2) oral indometacin, (3) solid food (pellets) during two hours and subcutaneous indometacin (production of ulcers in the gastric antrum), (4) Carrageen footpad edema.

Results: The three ATI receptor angiotensin antagonists yielded gastric cytoprotection against 96 degrees ethanol, almost total gastrointestinal protection against oral indometacin, prevented gastric ulcers formation in the antrum induced by subcutaneous indometacin, remarkable antiinflammatory response against neutrophil infiltration on the gastrointestinal mucosa, and anti-inflammatory effect in carrageen footpad edema.
