Second European evidence-based consensus on the prevention, diagnosis and management of opportunistic infections in inflammatory bowel disease
2014
The treatment of inflammatory bowel disease (IBD) has been revolutionised over the past decade by the increasing use of immunomodulators, mainly azathioprine (AZA)/6-mercaptopurine (6-MP) and methotrexate (MTX), together with the advent of biological therapy. Immunomodulators are being used more often and earlier in the course of the disease.1 The introduction of biologic agents, especially inhibitors of the key proinflammatory cytokine, tumor necrosis factor alpha (TNF-α) initiated a new therapeutic era, whose use has grown continuously since their introduction in 1998.2 With such immunomodulation, the potential for opportunistic infection is a key safety concern for patients with IBD. Opp…
Older age and markers of inflammation are strong predictors of clinical events in women with asymptomatic carotid lesions
2007
OBJECTIVE: Limited information exists regarding the association between markers of inflammation, such as high-sensitivity C-reactive protein (hs-CRP) and fibrinogen, and adverse events in postmenopausal women with subclinical atherosclerosis. Therefore, we investigated the prognostic impact of traditional risk factors and inflammation on adverse cardiac events in women with asymptomatic carotid lesions. DESIGN: We studied 250 postmenopausal women who were free of cardiovascular disease. Traditional cardiovascular risk factors were investigated, and laboratory analysis included measurement of plasma lipids, fibrinogen, and hs-CRP. The early phases of carotid atherosclerosis were assessed by …
Growth factor concentrations and their placental mRNA expression are modulated in gestational diabetes mellitus: possible interactions with macrosomia
2009
Abstract Background Gestational diabetes mellitus (GDM) is a form of diabetes that occurs during pregnancy. GDM is a well known risk factor for foetal overgrowth, termed macrosomia which is influenced by maternal hypergycemia and endocrine status through placental circulation. The study was undertaken to investigate the implication of growth factors and their receptors in GDM and macrosomia, and to discuss the role of the materno-foeto-placental axis in the in-utero regulation of foetal growth. Methods 30 women with GDM and their 30 macrosomic babies (4.75 ± 0.15 kg), and 30 healthy age-matched pregnant women and their 30 newborns (3.50 ± 0.10 kg) were recruited in the present study. Serum …
Le mode de financement et l'efficacité de la formation initiale des enseignants du primaire en Tunisie
1999
Actes des XIXè journées de l'AES; International audience; Depuis la réforme de 1991, la formation initiale des enseignants du primaire en Tunisie dure deux années au cours desquelles les élèves-enseignants sont astreints à un régime d'internat. Le financement de la formation des maîtres est assuré par les fonds publics, d'importantes aides sont octroyées aux élèves-enseignants. Leurs performances pédagogiques sont satisfaisantes, mais l'insertion des diplômés commence à être plus difficile.
Unveiling the Antecedents of International Diversification: An Agency Theory Approach
2014
While various studies have developed hypotheses about the antecedents of international diversification drawing mainly on the resource-based view, the behavioral theory of the firm, and the transaction costs literature, we advance our understanding by investigating the explanatory power of agency costs of free cash flow arguments. Using a sample panel of 167 Italian firms longitudinally evaluated during the 1980-2010 period, this study tests whether the firm’s choice to spread operations in multiple foreign countries is conditioned by excess of free cash flow and debt, especially in firm-contexts where agency problems are exacerbated by managers or large shareholders’ opportunism. We find th…
Assessing the impact of agri-environmental schemes on the eco-efficiency of rain-fed agriculture
2012
This paper analyses the impact of the Agri-environmental Extensification Scheme for the Protection of Flora and Fauna (F&F Scheme) on the eco-efficiency of a sample of dryland farms in the Spanish region of Castile and Leon. Using Data Envelopment Analysis (DEA) and the so-called program decomposition approach to efficiency measurement, we explore whether or not the production technology of the farms included in the F&F Scheme is more eco-efficient than the technology used by farms that are not included in the Scheme. The re-sults obtained confirm the foregoing hypothesis, providing evidence that environmental pres-sures could be reduced if all farms adopted the F&F Scheme technology. Furth…
Can technical, functional and structural characteristics of dental units predict Legionella pneumophila and Pseudomonas aeruginosa contamination?
2011
Legionella pneumophila and Pseudomonas aeruginosa are common colonizers of water environments, particularly dental unit waterlines. The aim of this study was to assess whether the technical, functional and structural characteristics of dental units can influence the presence and the levels of opportunistic pathogens. Overall, 42 water samples were collected from dental units in a teaching hospital in Palermo, Italy, including 21 samples from the 21 taps supplied by the municipal water distribution system and 21 samples from oral rinsing cups at 21 dental units. L. pneumophila was present in 16 out of 21 water samples (76.2%) from dental units, and the median concentration was higher in samp…
Probiotics Properties: A Focus on Pregnancy Outcomes.
2021
A healthy microbiome plays an important role in the prevention of illness and maintenance of overall health, including reproductive health. Although the therapeutic advantages of probiotics have been shown to run across multiple organ systems, their role in pregnancy is not well explored. The aim of this review is to highlight the potential advantages and adverse effects of probiotics in pregnancy. Data were collected from the literature over the past decade using PubMed, Medline, Google Scholar, Ovid, Scopus, and Science Direct. A total of 40 articles were utilized in this review. Collected data indicated that prenatal and post-natal supplementation with lactobacilli alone or lactobacilli …
The origin of strong ties: the role of weak ties in the evolution of alliance networks
2017
Studies on the structure of alliance networks have explained how the formation, maintenance, and decay of local within cluster ties and shortcuts with semi-distant and distant organizations drive the emergence and evolution of small world architecture in such networks. Interorganizational ties are distinguished into strong and weak on the basis of their strength. Nonetheless, by focusing mainly on strong alliances ties, previous research has fallen short to explain the role of weak ties among organizations for the evolution of alliance networks. With the aim of scrutinizing the role of weak ties in the establishment, maintaining, and transforming of alliance ties, we develop a conceptual fr…
Nuove ricerche tuniso-italiane al teatro romano di Althiburos
2017
Il progetto di rilievo, scavo, studio e valorizzazione del teatro romano di Althiburos (El M’deïna, Tunisia) vede coinvolti l’Institut National du Patrimoine, l’Università di Macerata ed il Politecnico di Bari. Nelle tre campagne sinora svolte è stato iniziato il programma di rilievo del monumento e catalogo degli elementi architettonici e sono stati iniziati alcuni saggi stratigrafici che hanno permesso di indagare le fasi più tarde della vita dell’edificio, da quando cioè, in età bizantina, il teatro venne trasformato in fortezza sino all’età moderna. Il progetto della missione congiunta tuniso-italiana prevede di riprendere quest’anno lo studio del monumento e del materiale già scavato e…
