Total and abdominal obesity are risk factors for gastroesophageal reflux symptoms in children.
No full textOBJECTIVES:
The association between GERD and obesity has been frequently reported in adults. Data in children are scarce and inconclusive, evaluating only general obesity. Central adiposity has never been investigated in children as a possible risk factor for GERD. The aims of the present study were to evaluate the prevalence of gastroesophageal reflux disease (GERD) symptoms in overweight and obese children in comparison with a general normal-weight population and whether the GERD symptoms are associated with waist circumference (WC).
METHODS:
The study population consisted of 153 healthy children. A detailed clinical history and a physical examination were obtained from each patient. A questionnaire on reflux symptoms was completed by caregivers.
RESULTS:
The reflux symptomatic score resulted significantly higher in obese than in normal-weight children and in children with WC >90th percentile compared with those with WC <75th percentile.
CONCLUSIONS:
These preliminary data show that both total and abdominal obesity are risk factors for the development of GERD symptoms in children. The risk of GERD symptoms rises progressively with the increase in both body mass index and waist circumference, even in normal-weight children
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
