BACKGROUND The Aklavik H. pylori Project (AHPP) (www.canhelpworkinggroup.ca) is a community-driven project examining Helicobacter pylori infection and its influence on health in a diverse Aboriginal community in the Northwest Territories. Initial research revealed that 58% of 333 participants who underwent a urea breath test (UBT) between 2007 and 2010 were H. pylori-positive. From 2008 to 2010...

This study investigated the distribution and chemical coding of neurons in intramural ganglia of the urinary bladder trigone (UBT-IG) and cervix (UBC-IG) in the male pig using combined retrograde tracing and double-labelling immunohistochemistry. Additionally, immunoblotting was used to confirm the presence of marker enzymes for main populations of autonomic neurons. Retrograde fluorescent trac...

BACKGROUND Behcet's disease (BD) is a multisystem disease of unknown etiology. There are several clues which may indicate an ethiopathogenesis role for Helicobacter pylori infection in this disease. METHODS In a case control study in an out patient department, 48 patients with BD were compared to age, sex matched controls regarding presence of H. pylori infection by serology and urea breath t...

We present a two-parameter survival distribution that has an upside-down bathtub (UBT, or humped-shaped) hazard function. This distribution provides biostatisticians, reliability engineers, and other statisticians with a second two-parameter UBT model whose closedform survivor function simplifies the analysis of right-censored data sets. We develop the distribution’s probabilistic and statistic...

Patients with atrophic corpus gastritis and elevated Helicobacter pylori antibody titers but 13C-urea breath test (13C-UBT) and histology results negative for H. pylori were randomized into eradication therapy or follow-up only. Antibody levels decreased significantly in six out of seven patients in the eradication group, while in the follow-up group, the titers declined in only one out of eigh...

The prevalence of Helicobacter pylori infection in a population-based sample of 477 children (mean age plus minus standard deviation, 5.8 plus minus 0.5 years) determined by the [(13)C]urea breath test ([(13)C]UBT) was 10.7% (95% confidence interval [CI], 8.1 to 13.8%), and that determined by salivary enzyme-linked immunosorbent assay (ELISA) was 11.9% (95% CI, 9.2 to 15.2%). Compared to the [(...
