Background and Aims: Diabetic foot (DF) disease is a current health and social burden. The authors aimed to identify the barriers to the DF management across Italy., Methods and Results: A questionnaire was submitted to Italian centres dedicated to DF care. The questionnaire was composed of 12 questions focused on the barriers to the DF management including timing of referral, hospital management, and community follow-up. Each centre could answer by choosing a score from 1 to 5 for every item with the following numerical variables: 1 = never; 2 = rarely; 3 = sometimes; 4 = often; 5 = always. Accordingly, for each item a national and regional score was reported and a comparison between regions was carried out. National and regional scores were estimated using the total score for each item as a numerator and the number of national centres included as a denominator. Among 102 centres, 99 were included and 3 were excluded due to missing data. The 99 centres belonged to 16 regions with the following distribution: Calabria 4, Campania 5, Emilia-Romagna 14, Friuli-Venezia-Giulia 4, Lazio 12, Liguria 4, Lombardy 10, Marche 1, Molise 1, Piedmont 5, Apulia 5, Sardinia 5, Sicily 4, Tuscany 11, Veneto 9, Umbria 5. The items with the highest score were late referral (3.3) and urgent surgery (3.2). The regions with the highest score were Molise (3.9) and Calabria (3.5)., Conclusion: The main issues across Italy were late referral and the requirement for urgent surgery for acute DF. In the regional scenario, the southern central areas showed more barriers than northern regions., Competing Interests: Declaration of competing interest The authors declares that there is no conflict of interest., (Copyright © 2020 The Italian Diabetes Society, the Italian Society for the Study of Atherosclerosis, the Italian Society of Human Nutrition and the Department of Clinical Medicine and Surgery, Federico II University.

1. Urbanization is a landscape process affecting biodiversity world-wide. Despite many urban-rural studies of bird assemblages, it is still unclear whether more species-rich communities have more individuals, regardless of the level of urbanization. The more-individuals hypothesis assumes that species-rich communities have larger populations, thus reducing the chance of local extinctions. 2. Using newly collated avian distribution data for 1 km(2) grid cells across Florence, Italy, we show a significantly positive relationship between species richness and assemblage abundance for the whole urban area. This richness-abundance relationship persists for the 1 km(2) grid cells with less than 50% of urbanized territory, as well as for the remaining grid cells, with no significant difference in the slope of the relationship. These results support the more-individuals hypothesis as an explanation of patterns in species richness, also in human modified and fragmented habitats. 3. However, the intercept of the species richness-abundance relationship is significantly lower for highly urbanized grid cells. Our study confirms that urban communities have lower species richness but counters the common notion that assemblages in densely urbanized ecosystems have more individuals. In Florence, highly inhabited areas show fewer species and lower assemblage abundance. 4. Urbanized ecosystems are an ongoing large-scale natural experiment which can be used to test ecological theories empirically.

Background: Present-day '-omics' technologies produce overwhelming amounts of data which include genome sequences, information on gene expression (transcripts and proteins) and on cell metabolic status. These data represent multiple aspects of a biological system and need to be investigated as a whole to shed light on the mechanisms which underpin the system functionality. The gathering and convergence of data generated by high-throughput technologies, the effective integration of different data-sources and the analysis of the information content based on comparative approaches are key methods for meaningful biological interpretations. In the frame of the International Solanaceae Genome Project, we propose here ISOLA, an Italian SOLAnaceae genomics resource., Results: ISOLA (available at http://biosrv.cab.unina.it/isola) represents a trial platform and it is conceived as a multi-level computational environment.ISOLA currently consists of two main levels: the genome and the expression level. The cornerstone of the genome level is represented by the Solanum lycopersicum genome draft sequences generated by the International Tomato Genome Sequencing Consortium. Instead, the basic element of the expression level is the transcriptome information from different Solanaceae species, mainly in the form of species-specific comprehensive collections of Expressed Sequence Tags (ESTs). The cross-talk between the genome and the expression levels is based on data source sharing and on tools that enhance data quality, that extract information content from the levels' under parts and produce value-added biological knowledge., Conclusions: ISOLA is the result of a bioinformatics effort that addresses the challenges of the post-genomics era. It is designed to exploit '-omics' data based on effective integration to acquire biological knowledge and to approach a systems biology view. Beyond providing experimental biologists with a preliminary annotation of the tomato genome, this effort aims to produce a trial computational environment where different aspects and details are maintained as they are relevant for the analysis of the organization, the functionality and the evolution of the Solanaceae family.
