Pathohistological Changes in the Gastric Mucosa in Correlation with the Immunohistochemically Detected Spiral and Coccoid Forms of .

Background: The coccoid form of ( is resistant to antibiotics. There are only a few studies that have analyzed the frequency of coccoid in patients with gastritis. The aim of this work was to examine the correlation between the form and the pathohistological characteristics of the stomach in patients with gastritis.

Early markers of gestational diabetes mellitus: what we know and which way forward?

Women's metabolism during pregnancy undergoes numerous changes that can lead to gestational diabetes mellitus (GDM). The cause and pathogenesis of GDM, a heterogeneous disease, are not completely clear, but GDM is increasing in prevalence and is associated with the modern lifestyle. Most diagnoses of GDM are made the guidelines from the International Association of Diabetes and Pregnancy Study Groups (IADSPG), which involve an oral glucose tolerance test (OGTT) between 24 and 28 weeks of pregnancy.

ICMJE authorship criteria are not met in a substantial proportion of manuscripts submitted to Biochemia Medica.

Introduction: Our aim was to investigate if: (a) authors of Biochemia Medica meet authorship criteria given by International Committee of Medical Journal Editors (ICMJE), (b) authorship violations are more frequent in submissions containing some type of scientific misconduct.

Materials And Methods: Self-reported authorship contributions regarding the three ICMJE criteria were analysed for all submissions to Biochemia Medica (February 2013-April 2015) which were forwarded to peer-review. To test the differences in frequencies we used Chi-squared test.

An Analysis of Medical Laboratory Technology Journals' Instructions for Authors.

Instructions for authors (IFA) need to be informative and regularly updated. We hypothesized that journals with a higher impact factor (IF) have more comprehensive IFA. The aim of the study was to examine whether IFA of journals indexed in the Journal Citation Reports 2013, "Medical Laboratory Technology" category, are written in accordance with the latest recommendations and whether the quality of instructions correlates with the journals' IF.

The evidence based practice for optimal sample quality for ammonia measurement.

Objectives: Pre-analytical factors are a major source of variability in laboratory results. Failure to identify these factors can lead to falsely increased or decreased results and to erroneous clinical decisions. We aimed to investigate several pre-analytical factors influencing ammonia measurement, and to quantify their effect on the apparent increase in ammonia concentration.
