Distribution of congenital melanocytic naevi and congenital naevus-like naevi in a survay of 3406 Italian schoolchildren
No full textBackground: Scanty information is available on the prevalence of congenital melanocytic naevi (CMN) and congenital naevus-like naevi (CNLN), particularly the small ones. Objectives: To estimate the prevalence of CMN/CNLN in Italian schoolchildren, and to assess variations according to potential risk factors for melanoma. Methods: We conducted a survey in 13 Italian areas on 3406 schoolchildren aged 12-17 years. Children were examined by dermatologists who assessed pigmentary traits and made a count of small (6-15 mm in diameter) and medium/large (> 15 mm) CMN/CNLN on 19 anatomical areas. Results: Overall, 592 children (17.4%) had one or more CMN/CNLN. Prevalence of small CMN/CNLN was 16.1%, and that of medium/large CMN/CNLN was 1.8%. There was no difference between age groups and sexes. CMN/CNLN were more frequent in children with a higher number of common melanocytic naevi (multivariate odds ratio, OR = 7.1 for the highest vs. the lowest quartile), consistent in small (OR = 7.2) and m..
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
Glycemic index, glycemic load and risk of gastric cancer
No full textBackground: Dietary carbohydrates have been directly associated with gastric cancer risk and have been considered general indicators of a poor diet. However, elevated levels of glucose and insulin elicited by consumption of high amounts of refined carbohydrates may stimulate mitogenic and cancer-promoting insulin-like growth factors (IGF). Glycemic index (GI) and glycemic load (GL), which represent indirect measures of dietary insulin demand, were analysed to understand further the association between carbohydrates and gastric cancer. Patients and methods: Data were derived from a hospital-based case-control study on gastric cancer, conducted in Italy between 1985 and 1997, including 769 cases with incident, histologically confirmed gastric cancer and 2081 controls admitted to the same hospital network as cases for acute, non-neoplastic diseases. All subjects were interviewed using a reproducible food frequency questionnaire. Results: The multivariate odds ratios (OR) for subsequent quartiles of dietary GL were 1.44 [95% confidence interval (CI) 1.11-1.87], 1.62 (95% CI 1.24-2.12) and 1.94 (95% CI 1.47-2.55). No consistent pattern of risk was seen with GI. The associations were consistent in different strata of age, education and body mass index, and were stronger in women. Conclusions: This study supports the hypothesis of a direct association between GL and gastric cancer risk, thus providing an innovative interpretation, linked to excess circulating insulin and related IGFs, for the association between carbohydrates and risk of gastric cancer
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
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Exploring Patterns of Alcohol Consumption in Adolescence: the Role of Health Complaints and Psychosocial Determinants in an Italian Sample
No full textAdolescents are particularly prone to engage in health-risk behaviors such as alcohol and substance use, which can significantly impact their present and future lives. Our study explores the factors contributing to (1) regular alcohol use (i.e., at least 3 to 5 times in the last 30 days) and (2) binge drinking (i.e., drinking at least five glasses of alcohol in a single sitting in the last 12 months) in adolescents, in the 2014 and 2018 waves of the Health Behavior in School-Aged Children (HBSC) survey conducted in the Lombardy region, Italy. Data collection used a stratified cluster sampling method to obtain a representative sample of adolescents (N = 6506) aged 11, 13, and 15 years (49.7% females). We used structural equation models (SEM) to explore the association of individual-related factors, including health complaints (i.e., somatic problems and psychological problems) and psychosocial variables (i.e., perceived support from family, peers, and teachers), on regular alcohol consumption and binge drinking. Overall, 9.9% of adolescents reported regular alcohol drinking and 18.3% binge drinking. The findings highlighted that higher somatic problems are associated with increased regular alcohol use (OR=1.24, 95% CI: 1.04–1.46), and higher psychological problems are associated with increased binge drinking (OR=1.33, 95% CI: 1.15–1.55). Moreover, lower perceived support from teachers is significantly associated with both regular (OR=1.41, 95% CI: 1.25–1.59) and binge drinking (OR=1.42, 95% CI: 1.28–1.57), and lower perceived student support is associated with a reduced risk of both usual drinking (OR=0.87, 95% CI: 0.77–0.98) and binge drinking (OR=0.86, 95% CI: 0.78–0.96). The study findings emphasize the importance of tackling somatic and psychological health and psychosocial support, particularly in the school environment, through interventions aimed at controlling adolescent drinking habits
Prevalence of atopic dermatitis in Italian schoolchildren: factors affecting its variation
No full textThe frequency of atopic dermatitis in Italian children and its relationship with selected variables were analysed in a large survey of skin health conducted in Italy. In 1997 we conducted a survey on schoolchildren aged 12-17 years from 13 areas of northern, central and southern Italy. For the present analyses, 3179 Caucasian children (1618 males, 1561 females) were considered. A diagnosis of atopic dermatitis was reported in 224 cases (7.0%). The frequency of reported atopic dermatitis was significantly higher in children with asthma (rate ratio (RR) 4.5; 95% confidence interval (CI) 3.1-6.5). The lifetime prevalence of a diagnosis of atopic dermatitis was higher among schoolchildren reporting a diagnosis of psoriasis (RR 5.5, 95% CI 3.0-10.1) and vitiligo, (RR 16.1, 95% CI 6.5-39.5). This study gives estimates of the lifetime prevalence of atopic dermatitis in adolescents in Italy and emphasizes the direct association between the condition and other immune-related skin diseases. © 2009 The Authors.
