Prevalence, socio-economic predictors and health correlates of food insecurity among Italian children- findings from a cross-sectional study
No full textConsidering food insecurity is a problem, even in developed countries, and the evidence gap regarding this issue in Italy, we
aimed to assess the prevalence of food insecurity in a sample of Italian children and examine socio-economic and health
correlates. This cross-sectional study was conducted in paediatric practices. Parents answered to the 18-items of the
Household Food Security Module, 8 of which concern children. Paediatricians answered a questionnaire on children’s health.
Socio-economic and health correlates of food insecurity in children were assessed using univariable and multivariable logistic
regression. Among 573 households with children, 15·4% were food insecure, while 9·1% of children were food insecure. Socioeconomic
factors associated to food insecurity were living in south Italy, households with three or more children, lower
household yearly income, worse economic situation description and younger parents. Food insecure children were less likely
to have a normal relational [ aOR 0.31 (CI 0.11-0.85)] and physical development [aOR 0.32(CI 0.15-0.65) and had more school
difficulties [aOR 3.1(CI 1.33-7.24)] compared to their food secure peers. Food insecure children had higher odds of a deterioration
in their health since birth and of a worse perceived health status, as reported by their parents. Considering the results in this
sample and the lack of research regarding this issues in Italy and Europemore broadly, we call for consistent, nationalmonitoring
to determine the magnitude of the problem of food insecurity in households with children in Italy and to examine the socioeconomic
variables and health implications in different contexts
Ru(Ii)-dppz derivatives and their interactions with dna: Thirty years and counting
No full textTransition metal complexes with dppz-type ligands (dppz = dipyrido[3,2-a:2′,3′-c]phenazine) are extensively studied and attract a considerable amount of attention, becoming, from the very beginning and increasingly over time, a powerful tool for investigating the structure of the DNA helix. In particular, [Ru(bpy)2(dppz)]2+ and [Ru(phen)2(dppz)]2+ and their derivatives were extensively investigated as DNA light-switches. The purpose of this mini-review, which is not and could not be exhaustive, was to first introduce DNA and its importance at a biological level and research in the field of small molecules that are capable of interacting with it, in all its forms. A brief overview is given of the results obtained on the Ru-dppz complexes that bind to DNA. The mechanism of the light-switch active in this type of species is also briefly introduced along with its effects on structural modifications on both the dppz ligand and the ancillary ligands. Finally, a brief mention is made of biological applications and the developments obtained due to new spectroscopic techniques, both for understanding the mechanism of action and for cellular imaging applications
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
