No full textBackground - It has recently been suggested that primary lactase deficiency mighthave been selected for by malaria, as has been previously shown to occur for thalasaemia and glucose 6-phosphate dehydrogenase (G6PD) deficiency. Aims - To test this hypothesis, the prevalence of primary lactase deficiency in G6PD deficient subjects and in controls from the area of Sassari (Northern Sardinia) was determined, which in the past was characterised by an intermediate malarial endemicity. Subjects - 7O adult subjects with G6PD deficiency, 34 of whom had a past history of favism, and 50 age matched control subjects. Methods - The capacity to absorb lactose was assessed by measuring breath hydrogen production after oral administration of lactose (50 g) by a gas chromatographic method. Results - Twenty percent of G6PD deficient subjects with a positive history of favism and 22% of G6PD deficient subjects without a positive history of favism were lactose absorbers compared with 14% lactose absorbers in the control group. The differences were not statistically significant. Conclusions - These data show that the prevalence of primary lactase deficiency in the area of Sassari is relatively high, but comparable to that seen in the adult population from another area of southern Italy (Naples) where malaria was less endemic

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
Seroprevalence of Helicobacter pylori in children with type 1 diabetes mellitus in Sardinia
No full textA few studies have reported an increased prevalence of Helicobacter pylori (HP) infection in diabetic subjects, which may be one of the causes of gastrointestinal symptoms and chronic atrophic gastritis frequently seen in diabetes of long duration. We determined the prevalence of HP infection in children and adolescents with Type 1 diabetes mellitus (T1DM) in the area of Sassari (northern Sardinia, Italy), which is characterized by an ethnically homogenous population at high risk of T1DM. HP IgG and IgA titres were measured in 138 patients with T1DM and 138 age-matched healthy controls. The percentage of infected subjects did not differ between T1DM patients (29.7%) and controls (32.6%). Globally, infected subjects were more than I yr older (13.0 +/- 2.7 yr) than non-infected ones (11.8 +/- 2.9 yr), independently of the presence of T1DM; in most HP-positive subjects infection was asymptomatic, and only 2 subjects in each group reported clinically relevant symptoms. HP-positive and HP-negative diabetic patients had the same duration of the disease (5.6 +/- 3.5 vs 5.5 +/- 3.6 yr) and received very similar doses of insulin (0.94 +/- 0.27 vs 0.96 +/- 0.4 IU/kg/d), whereas mean HbA(1c) was significantly lower in HP-positive patients (7.8 +/- 1.6 % vs 8.6 +/- 1.7 %, p=0.02). We conclude that the prevalence of HP infection is not higher in Sardinian children with T1DM as compared to controls of similar age, and the overall clinical impact of HP infection in terms of gastrointestinal symptoms and diabetic control seems to be low.

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
