Comparison of the yield from two faecal immunochemical tests at identical cutoff concentrations - a randomized trial in Latvia.

Objective: We have compared the performance of two faecal immunochemical tests (FIT) in an average-risk population.

Materials And Methods: Altogether, 10 000 individuals aged 50-74 were selected randomly from the population of Latvia in 2011 and assigned randomly either to OC-Sensor or to FOB Gold single-time testing. Positivity of the test, frequency of colonic lesions, number needed to screen (NNscreen) and scope for the detection of an advanced neoplasm (cancer and advanced adenoma) were compared between the tests using the same cutoff concentrations in µg/g faeces.

Different Pattern of Inflammatory and Atrophic Changes in the Gastric Mucosa of the Greater and Lesser Curvature.

Background And Aims: Appropriate biopsy sampling is important for the classification of gastritis, yet the extent of inflammation and atrophy of different regions of the stomach with chronic gastritis have been addressed only in a few studies. The aim of our study was to analyze the inflammatory, atrophic and metaplastic changes in the greater and lesser curvature of the antrum and corpus mucosa.

Methods: 420 patients undergoing upper endoscopy were enrolled in the study.

Pepsinogen testing for evaluation of the success of Helicobacter pylori eradication at 4 weeks after completion of therapy.

Background And Objective: Pepsinogen levels in plasma are increased by inflammation in the gastric mucosa, including inflammation resulting from Helicobacter pylori infection. A decrease in pepsinogen II level has been suggested as a reliable marker to confirm the successful eradication of infection. The aim of our study was to evaluate the potential role of pepsinogens I and II, gastrin-17 and H.

Interobserver variation in assessment of gastric premalignant lesions: higher agreement for intestinal metaplasia than for atrophy.

Background: Either atrophy or intestinal metaplasia of the gastric mucosa are considered premalignant lesions. The new operative link for gastritis assessment staging system is based on the detection of atrophy, and the operative link for assessment of intestinal metaplasia staging system is based on the detection of intestinal metaplasia. Good interobserver agreement is necessary for identification of any premalignant condition.

Role of the nuclear matrix proteins in malignant transformation and cancer diagnosis.

The nuclear matrix (NM) is the structural framework of the nucleus that consists of the peripheral lamins and pore complexes, an internal ribonucleic protein network, and residual nucleoli. Differences between the nuclear matrix protein (NMP) composition of transformed cells and their normal homologues were detected in numerous cases. Actually several tumor-specific nuclear matrix proteins (NMPs) are proposed for diagnostic of bladder, breast, colon and some other cancers.

Serological evidence for protection by human papillomavirus (HPV) type 6 infection against HPV type 16 cervical carcinogenesis.

Human papillomavirus (HPV) exists as more than 100 genotypes. It is not well-established whether the different HPV types interfere with infection or pathogenesis by each other. Possible interactions in cervical carcinogenesis between infection with the most common HPV types (6, 11, 16, 18 and 33) were studied in a seroepidemiological case- control study of 218 women with primary untreated cervical cancer and 219 healthy age-matched control women.
