Increased prevalence of Helicobacter pylori in patients with diabetes mellitus
No full textBACKGROUND: Whilst upper gastrointestinal disturbances are frequently observed in
patients with diabetes mellitus, little is known about the prevalence of
Helicobacter pylori infection and peptic disease in these patients.
AIM: To evaluate prevalence of Helicobacter pylori infection and peptic disease
lesions in diabetics with dyspeptic symptoms.
PATIENTS AND METHODS: Study population comprises 74 consecutive diabetes mellitus
patients with dyspepsia and 117 consecutive non diabetic dyspeptic patients. Upon
enrolment, each patient completed an interview screening questionnaire to obtain
information concerning presence and severity of dyspepsia. All patients underwent
upper gastrointestinal endoscopy with biopsy specimens being collected from
gastric antrum and body Helicobacter pylori was evaluated in each patient by
rapid urease test and histology (Giemsa). Gastritis was classified according to
the Sydney System. Statistical analysis was performed by chi-square, Fisher exact
or t test and logistic regression analysis. A p value <0.05 was considered
significant.
RESULTS: Prevalence of Helicobacter pylori infection was found to be
significantly higher in diabetics than in controls. The prevalence rate of
endoscopic lesions was comparable in the two groups, but the association between
endoscopic lesions and Helicobacter pylori infection was significantly higher in
diabetics. Overall, the presence of chronic gastritis, both non atrophic and
atrophic, as well as intestinal metaplasia were comparable in the two groups of
patients, whilst the association between chronic gastritis and Helicobacter
pylori infection or gastritis activity were significantly higher in diabetics. In
neither group, was any correlation found between severity of dyspepsia and
presence of endoscopic lesions, chronic gastritis or Helicobacter pylori
infection.
CONCLUSIONS: These data show a higher prevalence of Helicobacter pylori infection
in diabetes mellitus patients with dyspepsia. Helicobacter pylori infection was
significantly associated both with the presence of endoscopic lesions and chronic
gastritis in diabetic patients, but not in the controls
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
