Development and Assessment of a Helicobacter pylori Medication Adherence and Stomach Cancer Prevention Curriculum for a Chinese American Immigrant Population.

Chinese American immigrants are at increased risk for Helicobacter pylori infection and stomach cancer. Despite their increased risk, very few prevention strategies exist which target this vulnerable population. The purpose of this article is to present the stakeholder engaged development, review, assessment, refinement, and finalization of a H.

Assessment of Risk and Sero-Prevalence of Helicobacter pylori Colonization among Remote Orang Asli Tribes in Peninsula Malaysia.

The epidemiology of Helicobacter pylori (H. pylori) infection is related to human poverty with marked differences between developing and developed countries. Socioeconomic factors and living standards are the main determinants of the age-dependent acquisition rate of H.

A review of Helicobacter pylori diagnosis, treatment, and methods to detect eradication.

Helicobacter pylori (H. pylori) affects nearly half of the world's population and, thus, is one of the most frequent and persistent bacterial infections worldwide. H.

mRNA levels of TLR4 and TLR5 are independent of H pylori.

Aim: To determine if the presence H pylori or its virulence affect toll-like receptor 4 (TLR4) and TLR5 mRNA expression levels.

Methods: For the in vivo assays, gastric biopsies were obtained from 40 patients and H pylori status was determined. For the in vitro assays, human gastric adenocarcinoma mucosal cells (AGS) were cultured in the presence or absence of twelve selected H pylori strains.

Utility of diagnostic tests for detection of Helicobacter pylori in children in northeastern Mexico.

Background: The presence of Helicobacter pylori in pediatric population has been associated with recurrent abdominal pain (RAP), although this association is unclear. One of the major problems in studying the role of H. pylori in RAP is that methods used to detect the bacteria in children have poor sensitivity and specificity.

[Development of a protocol of pyrosequencing for determination of the polymorphism at position -31 of the interleukin-1beta gene in the study of risk of development of stomach cancer].

Background: Single nucleotide polymorphism association studies among cases and controls have been widely used for genetic analysis. The pyrosequencing method is based on indirect luminometric quantification of the pyrophosphate that is released as a result of nucleotide incorporation onto an amplified template. It has the advantages of accuracy, flexibility, automatization and speed when compared with PCR-RFLP method.

Diagnostic utility of invasive tests and serology for the diagnosis of Helicobacter pylori infection in different clinical presentations.

Background: Invasive and noninvasive tests are used for the diagnosis of Helicobacter pylori infection. The aim of this study was to determine the diagnostic utility of rapid urease test (RUT), culture, histology and serology for the diagnosis of H. pylori in patients with different clinical presentations.

Seroprevalence of Helicobacter pylori in New York City populations originating in East Asia.

Helicobacter pylori prevalence is higher in developing countries than in industrialized countries, and within the latter, higher among immigrants than among nativeborn residents. Using a point-prevalence survey, we sought to identify risk factors for H. pylori seropositivity in US urban East Asian-born populations.

Role of p53 codon 72 polymorphism in the risk of development of distal gastric cancer.

Objective: Mutations in the codon 72 of exon 4 in the p53 gene have been associated with higher risk in the development of several types of cancer. This polymorphism occurs with two alleles encoding either arginine (CGC) or proline (CCC). The aim of this study was to assess the role of the codon 72 polymorphism of p53 in the risk for the development of distal gastric cancer (GC) in a Mexican population.

Role of the polymorphic IL-1B, IL-1RN and TNF-A genes in distal gastric cancer in Mexico.

Several cytokine gene polymorphisms have been associated with increased risk of distal gastric cancer (GC) and its precursor histological markers in Caucasian, Asian and Portuguese populations although little is known about their role in other ethnic groups. Our study investigates the role of the IL-1B-31, IL-1RN and TNF-A-308 gene polymorphisms as risk factors for the development of GC in a Mexican population. We studied 278 patients who were enrolled at the Hospital Universitario Dr.

[Role of polymorphism of certain cytokines in gastric cancer in Mexico. Preliminary results].

Background: Interleukin-10, tumor necrosis factor alpha, Interleukin-1 beta and interleukin-1 receptor antagonist cytokines modulate the inflammatory response in presence of Helicobacter pylori. Pro-inflammatory interleukin 10 (IL-10-592, -1082), TNF alpha (TNF alpha-308), interleukin-1 beta and interleukin-1 receptor antagonist (IL-1B-31*C and IL-1RN*2/*2) genotypes have been associated with higher risk of gastric cancer in Caucasians. The aim of this study was to investigate whether these same genotypes are involved in susceptibility to gastric cancer in Mexican population.

Comparison of Helicobacter pylori prevalence in symptomatic patients in northeastern Mexico with the rest of the country: its association with gastrointestinal disease.

Background: Prevalence of Helicobacter pylori varies among different geographic regions. The aim of this study was to assess H. pylori prevalence in symptomatic patients in northeastern Mexico and its possible association of H.
