Functional assessment of cancer therapy questionnaire for breast cancer (FACT-B+4): Italian version validation

BACKGROUND: Improvements in breast cancer diagnosis and treatment led to an increased incidence of survivors' rate. The healthcare system has to face new problems related not only to the treatment of the disease, but also to the management of the quality of life after the diagnosis. The aim of this study was to validate the Italian version of the Functional Assessment of Cancer Therapy - Breast (FACT-B+4) questionnaire and to evaluate its reliability. METHODS: The questionnaire was administered twice, with an interval of three days between each administration, to a cohort of women of the Breast Surgical Unit, PoliclincoUmberto I. Cronbach's alpha was used as a measure of the internal consistency of the Italian version. RESULTS: The Italian version of the tool was administered to 55 subjects. The Cronbach's alpha for most scores registered values >0.7, both at baseline and at the follow-up analysis, therefore the subscale showed good internal consistency. CONCLUSIONS: The Italian version of FACT-B+4 demonstrated acceptable reliability properties in the Breast Unit patients. The use of this questionnaire seemed to be effective and in line with the results derived from the English and Spanishversions. Internal consistency and validity had similar performance results

Ovine Catarrhal fever (bluetongue): Analysis of Culicoides species in seropositive farms

Bluetongue (BT) is an orbiviral disease of wild and domestic ruminants, mainly sheep. In Sicily, the first Bluetongue outbreak occurred in October 2000; there have been 76 recorded outbreaks so far. The National Surveillance Plan, based on European Union Commission Decision 138/2001/CE, establishes serological and entomological surveys. This plan consists of controls of seronegative cattle, called 'sentry' as indicators for the presence and circulation of virus in defined areas. To check the seroconversions, the regional territory has been subdivided in 400 km2 areas including 58 seronegative cattle, periodically checked by serological tests. All positive sera have been tested to detect the specific serotype by the National Reference Centre for Exotic Diseases (CESME) at the Istituto Zooprofilattico Sperimentale Abruzzo e Molise in Teramo (IZS Teramo). Moreover, entomological surveillance has been implemented in seropositive herds, to investigate the presence of insect vectors belonging to Culicoides genus. The goal of the present communication is to report on the different species of Culicoides found in the farms with Bluetongue virus and to investigate on the probable role of new competent vectors. This paper concerns data analysis of 581 light-trap catches collected in 321 farms from 2003 to 2008. We observed that 82% of checked farms were positive for Culicoides spp., and only 10% of the farms were positive for Culicoides imicola. © 2010 Blackwell Verlag GmbH

An innovative method for the detection of contaminant viral genome in cell cultures

The use of cell cultures involves different fields of biology, from diagnosis to research. Moreover, technologies based on animal cells represent a useful tool to the development of biological products for the prophylaxis and therapy in humans and animals. Therefore, it is necessary to perform quality controls, including virological tests. Several tests performed in research laboratories are able to discriminate one or more viral species, but it is not possible to demonstrate the presence of contaminant viral genome with one non-specific method. The aim of this work consisted on the realization of a biomolecular method able to detect and to identify by sequencing extraneous viral genome in cell cultures of animal and human origin in the absence of any specific information about the virus

Risultati di un test RFLP su ceppi vaccinali di Canine Distemper Virus in Italia

Canine Distemper (CD) is a highly contagious and multisystemic viral disease of domestic and wild carnivores. A published Restriction Fragment Length Polymorphism (RFLP) test, based on the presence of a PsiI cleavage site on hemagglutinin (H) gene, allows a rapid differentiation of all currently used vaccine strains by virulent field strains. The present study describes the results of this test carried out on different CD vaccines available in Italy in 2010. RFLP has also revealed that the CD strain present in the Vanguard (Pfizer Animal Health) vaccine reacts as a wild-type strain. Moreover, genetic analysis of H gene sequence has showed that Vanguard vaccine strain does not cluster in the group of vaccine strains (America-1), as expected based on the product description provided by the manufacturer, but it is more closely related to wild-type strains of the America-2 group. However, this protocol shows significant advantages to identify CD wild-type strains

Quality controls for cell cultures: identification of interspecies cross-contamination by PCR-RFLP analysis of the cytochrome b gene

Cross-contaminations of a cell line with cells of different species represent a potential risk in laboratories handling human and animal cells. Therefore, it is necessary to control such contaminations. Tests based on mitochondrial DNA (mtDNA) are used in forensic analysis, phylogenetic studies and in food authentication. However, the use of mtDNA in quality controls of cell cultures is recent. Mitochondrial sequence differences of closely related animal species are five- to tenfold higher than those of nuclear genes. On the contrary, intraspecies variation in mitochondrial sequences is low in most animal species. Moreover, each cell contains 100–10.000 mitochondrial genomes. The amount of mtDNA is greater than nuclear DNA, so that mtDNA can be analyzed also from small or partially degraded samples. In the present study, a method based on a PCR-Restriction Fragment Length Polymorphism (RFLP) analysis of the mitochondrial cytochrome b gene was used (2). This gene has some stable sequences which are recognized from universal primers and some variable sequences used for animal species identification by PCR-RFLP method

Il PON Reti e Mobilità e gli obiettivi di Sostenibilità: il ruolo del Piano di Monitoraggio Ambientale

The National Operative Program (PON) “Reti e mobilità” has been approved by European Commission on the 7th of December 2007. The strategic approach of the PON, exclusively devoted to the socalled “convergence regions” of Italy (Campania, Calabria, Sicilia, Puglia), aims to: 1. improve the modal balance by an economic, social and environmental perspective; 2. develop the inter-modality in order to move towards the integration of convergence area into the network of the European transport system; 3. improve the mobility and the accessibility, also to reduce the traffic congestion; 4. increase the efficiency related to security standards, to management techniques and to the quality of transportation services in the sector of freight; 5. guarantee the reduction of environmental impacts through a global improvement of the efficiency of the transport systems. In such a way it is clear that the PON “Reti e mobilità” takes greatly into account the Sustainability principles recognized at European scale as attested by the budget, namely over the 70% of the entire fund, associated with low-impacts infrastructures (railways and harbors). The PON has been submitted to the SEA procedure, following what the 2001/42/CE Directive establishes. The Environmental Report of PON devotes great attention to the monitoring activity as shown by the reported recommendation about the need for adequate measures for the environmental monitoring, also in order to apply corrective measures during the implementation of the program. By this point of view, a first and important step has been the elaboration of the “Environmental Monitoring Plan” (EMP) that represents the main methodological document for the following implementation of the monitoring activity. This paper, after a brief presentation of the program and of the objectives of Sustainability that the Programs aims to pursue through the realization of specific projects, is devoted to introduce the Environmental Monitoring Plan of the PON that has been approved by the Ministry of the Infrastructures and Transport -in charge as Management Authority of the PON- in February 2011. In detail, the PMA represents the tool through which, the Management Authority, that has specific responsibilities and functions in terms of monitoring and environmental assessment of the program, controls the significant impacts on the environment caused by the implementation of the PON and verify the level of achievement of the established objectives of environmental sustainability. The structure of EMP is based on three main aspects: 1) the adoption of the results of other interesting experiences carried out by experts institutions on the topic; 2) an approach favoring the creation of an “integrated” monitoring system with the others Operative Programs activated at regional scale; 3) the implementation of a cooperation and shared process with all the directly-involved actors

Aerobic training and angiogenesis activation in patients with stable chronic heart failure: a preliminary report.

The pathophysiology of chronic heart failure (CHF) involves multiple hystologic and molecular alterations. To determine the effects of physical training on circulating endothelial progenitor cells (EPCs), angiogenesis (angiogenin, angiopoietin-1 and -2, VEGF, Tie-2, SDF-1α) and inflammation (IL-6, CRP), we compared data obtained from 11 CHF pts before and after 3 months aerobic exercise training, to those from 10 non trained CHF pts (CHF-C group, age 64 + 2 years, NYHA 2). At the end of the study, EPCs count and AP-2 serum levels significantly increased in the CHF-TR group. These preliminary data suggest a significant effect of even a short program of physical training on angiogenic activation and endothelial dysfunction

SERUM IONIZED MAGNESIUM IN DIABETIC OLDER PERSONS

Objective. Several alterations of magnesium metabolism have been associated with type 2 diabetes pathophysiology, a condition particularly frequent in older persons. We aimed to evaluate serum total (Mg-tot) and serum ionized magnesium (Mg-ion) in older persons with type 2 diabetes in order to explore clinically applicable methods for the detection of magnesium deficit. Material/Methods: Mg-tot and Mg-ion were measured in 105 fasting subjects with type 2 diabetes (mean age: 71.10.8 years; M/F: 45/60) and in 100 age-matched non-diabetic control persons (mean age: 72.20.8 years; M/F: 42/58). Results: Mg-ion concentrations were significantly lower in diabetic persons compared with controls (0.490.05 mmol/L vs. 0.550.05 mmol/L; p<0.001). Mg-tot was also slightly but significantly lower in diabetic patients (0.820.007 mmol/L vs. 0.840.006 mmol/L; p<0.05). There was an almost complete overlap in the values of Mg-tot in older diabetic patients and controls; conversely, 44.8% of diabetic patients had Mg-ion values below 0.47 mmol/L, while none of the controls did. After adjustment for age, sex, BMI, and triglycerides, Mg-tot was significantly associated with FBG in all the participants (p<0.05) and Mg-ion was significantly associated with FBG in all the participants (p<0.01) and with HbA1c in diabetic participants (p<0.001). Conclusions: Alterations of magnesium serum concentrations are common in type 2 diabetic older adults; Mg-ion evaluation may help to identify subclinical magnesium depletion (i.e. in patients with normal Mg-tot); the close independent associations of Mg-tot and Mg-ion with FBG and with HbA1c reinforce the possible link between magnesium homeostasis and altered glucose metabolism
