Knowledge about cancer screening programmes in Sardinia

BackgroundHigh level of attendance by population is considered a proof of the efficacy in the screening programmes.  Public health aims to increase people’s attendance to cancer screening.The study aimed at assessing the level of knowledge and awareness about screening of citizens in Cagliari, from June to July 2016.Methods Recruiting took place near the atrium of the two main shopping centres of the city.  The sample included 270 adults (138 men), 18-75 years old (mean age 46 years old). The information gathered from interviews were categorized dichotomizing answers according to the knowledge and understanding of the discussed topics. Descriptive analysis was performed. The Chi-square test was used to assess gender and educational differences.ResultsResults show that population's knowledge of screening is limited. Although the word "screening" is known, only half of the people who declared to have heard of this word know about the aim of screening. Colorectal cancer screening is the least known.  Men and people with lower education are less informed than the other people are. ConclusionIn order to raise knowledge and awareness about cancer screening, special attention should be paid to communication and to the use of plain language. Future action should highlight the benefit of the screening procedure and thus contributing to spread the cancer prevention culture. Gender and socioeconomic inequalities must be taken into account when planning screening communication campaigns. General practitioner are highly trusted by people. They could play a decisive role to promote screening attendance.   

Unawareness of Alcoholic Content of Alcopops among 13-Year Old Italian Teenagers.

Aims: Alcopops are ready-mixed drinks containing approximately the same amount of alcohol as beer, usually sweet, and flavoured, particularly appealing to young people. The present study was aimed to investigate whether young adolescents aged 12-14 years, corresponding to the average age of the first drink, are capable of identifying the presence of alcohol in these beverages. Methods: Administration of a questionnaire comprising 8 questions investigating knowledge and consumption of different alcoholic and non-alcoholic beverages to a sample of 13-year old Italian students. Results: More than 20% of a sample of 224 students reported that they were unaware of the alcoholic content of alcopops at the age of the first drink. The number of students unable to distinguish alcopops from non-alcoholic beverages was significantly higher than students who were not able to distinguish beer from alcohol-free beverages. Conclusions: At the age of the first drink, the identification of alcopops as alcoholic beverages is more difficult than that of other beverages containing the same amount of alcohol. Information aimed at increasing the ability of adolescents to distinguish between alcoholic and non-alcoholic beverages should be provided to young adolescent students before they start drinking

Vaccination attitude and communication in early settings: An exploratory study

Background: This study assesses attitudes towards vaccination in mothers of new-born babies and explores its association with different exposures to communication. Methods: Data were collected through questionnaires administered by means of interviews. Results: Data highlighted that 20% of mothers showed an orientation towards vaccine hesitancy. As for the reasons behind the attitude to vaccine hesitancy, data showed that concern is a common feature. As for the different exposures to communication, 49% of mothers did not remember having received or looked for any information about vaccination during pregnancy and post-partum; 25% stated they received information from several healthcare and non-healthcare sources; 26% declared having received or looked for information by means of healthcare and non-healthcare sources, as well as having taken part in a specific meeting during antenatal classes or at birth centres. The attitude towards vaccine hesitancy tends to reduce as exposure to different communication increases. Conclusions: This study supports the hypothesis that participation in interactive meetings in small groups focused on vaccination during the prenatal course or at the birth point may act as an enabling factor contributing to a decrease in the tendency to experience vaccine hesitation

Haplotype affinities resolve a major component of goat (<i>Capra hircus</i>) MtDNA D-loop diversity and reveal specific features of the Sardinian stock

Goat mtDNA haplogroup A is a poorly resolved lineage absorbing most of the overall diversity and is found in locations as distant as Eastern Asia and Southern Africa. Its phylogenetic dissection would cast light on an important portion of the spread of goat breeding. The aims of this work were 1) to provide an operational definition of meaningful mtDNA units within haplogroup A, 2) to investigate the mechanisms underlying the maintenance of diversity by considering the modes of selection operated by breeders and 3) to identify the peculiarities of Sardinian mtDNA types. We sequenced the mtDNA D-loop in a large sample of animals (1,591) which represents a non-trivial quota of the entire goat population of Sardinia. We found that Sardinia mirrors a large quota of mtDNA diversity of Western Eurasia in the number of variable sites, their mutational pattern and allele frequency. By using Bayesian analysis, a distance-based tree and a network analysis, we recognized demographically coherent groups of sequences identified by particular subsets of the variable positions. The results showed that this assignment system could be reproduced in other studies, capturing the greatest part of haplotype diversity. We identified haplotype groups overrepresented in Sardinian goats as a result of founder effects. We found that breeders maintain diversity of matrilines most likely through equalization of the reproductive potential. Moreover, the relevant amount of inter-farm mtDNA diversity found does not increase proportionally with distance. Our results illustrate the effects of breeding practices on the composition of maternal gene pool and identify mtDNA types that may be considered in projects aimed at retrieving the maternal component of the oldest breeds of Sardinia.</br

Antonovsky’s Sense of Coherence Scale: Cultural Validation of Soc Questionnaire and Socio-Demographic Patterns in an Italian Population

BACKGROUND: The theory of salutogenesis entails that the ability to use resources for one's wellbeing is more important than the resources themselves. This ability is referred to as the Sense of Coherence (SOC). This paper present the cross-culturally adapted version of the Italian questionnaire (13 items), and the psychometric and statistical testing of the SOC properties. It offers for the first time a view of the distribution of SOC in an Italian sample, and uses a multivariate method to clarify the effects of socio-demographic determinants on SOC. METHODS: The cross-cultural adaptation of the English SOC questionnaire was carried out according to the guidelines reported in literature. To evaluate the psychometric and statistical properties we assessed reliability, validity and frequency distribution of the collected data. A Generalised Linear Model was used to analyse the effects of socio demographic variables on SOC. RESULTS: The Italian SOC scale demonstrates a good internal consistency (α = 0.825). The model obtained with factorial analysis is not related to the traditional dimensions of SOC represented in more than one factor. The multivariate analysis highlights the joint influence of gender, age and education on SOC. CONCLUSION: The validated Italian questionnaire is now available. Socio-demographic variables should be taken into account as confounders when SOC values among different populations are compared. Presenting data on SOC of the Italian population makes a control population available for comparisons with specific subgroups, such as patient populations. Now, the Italian challenge is to integrate the salutogenic approach into Public Health police

GATA2 Promotes Hematopoietic Development and Represses Cardiac Differentiation of Human Mesoderm.

In vertebrates, GATA2 is a master regulator of hematopoiesis and is expressed throughout embryo development and in adult life. Although the essential role of GATA2 in mouse hematopoiesis is well established, its involvement during early human hematopoietic development is not clear. By combining time-controlled overexpression of GATA2 with genetic knockout experiments, we found that GATA2, at the mesoderm specification stage, promotes the generation of hemogenic endothelial progenitors and their further differentiation to hematopoietic progenitor cells, and negatively regulates cardiac differentiation. Surprisingly, genome-wide transcriptional and chromatin immunoprecipitation analysis showed that GATA2 bound to regulatory regions, and repressed the expression of cardiac development-related genes. Moreover, genes important for hematopoietic differentiation were upregulated by GATA2 in a mostly indirect manner. Collectively, our data reveal a hitherto unrecognized role of GATA2 as a repressor of cardiac fates, and highlight the importance of coordinating the specification and repression of alternative cell fates.Ramón y Cajal Program, Spanish Ministry of Economy, Industry, and Competitiveness, Spanish Cancer Association, FERO, Instituto de Salud Carlos III, European Social Fund, MINECO, PERIS Program of the Generalitat de Catalunya, Obra Social la Caixa-Fundacion Josep Carreras, Spanish Institute of Health Carlos III, Wellcome Trust, MRC, CRUK, NIH-NIDD

Population Based Study of 12 Autoimmune Diseases in Sardinia, Italy: Prevalence and Comorbidity

BACKGROUND: The limited availability of prevalence data based on a representative sample of the general population, and the limited number of diseases considered in studies about co-morbidity are the critical factors in study of autoimmune diseases. This paper describes the prevalence of 12 autoimmune diseases in a representative sample of the general population in the South of Sardinia, Italy, and tests the hypothesis of an overall association among these diseases. METHODS: Data were obtained from 21 GPs. The sample included 25,885 people. Prevalence data were expressed with 95% Poisson C.I. The hypothesis of an overall association between autoimmune diseases was tested by evaluating the co-occurrence within individuals. RESULTS: Prevalence per 100,000 are: 552 rheumatoid arthritis, 124 ulcerative colitis, 15 Crohn's disease, 464 type 1 diabetes, 81 systemic lupus erythematosus, 124 celiac disease, 35 myasthenia gravis, 939 psoriasis/psoriatic arthritis, 35 systemic sclerosis, 224 multiple sclerosis, 31 Sjogren's syndrome, and 2,619 autoimmune thyroiditis. An overall association between autoimmune disorders was highlighted. CONCLUSIONS: The comparisons with prevalence reported in current literature do not show outlier values, except possibly for a few diseases like celiac disease and myasthenia gravis. People already affected by a first autoimmune disease have a higher probability of being affected by a second autoimmune disorder. In the present study, the sample size, together with the low overall prevalence of autoimmune diseases in the population, did not allow us to examine which diseases are most frequently associated with other autoimmune diseases. However, this paper makes available an adequate control population for future clinical studies aimed at exploring the co-morbidity of specific pairs of autoimmune disease

Localization of anatomical changes in patients during proton therapy with in-beam PET monitoring: a voxel-based morphometry approach exploiting Monte Carlo simulations

Purpose: In-beam positron emission tomography (PET) is one of the modalities that can be used for in vivo noninvasive treatment monitoring in proton therapy. Although PET monitoring has been frequently applied for this purpose, there is still no straightforward method to translate the information obtained from the PET images into easy-to-interpret information for clinical personnel. The purpose of this work is to propose a statistical method for analyzing in-beam PET monitoring images that can be used to locate, quantify, and visualize regions with possible morphological changes occurring over the course of&nbsp;treatment. Methods: We selected a patient treated for squamous cell carcinoma (SCC) with proton therapy, to perform multiple Monte Carlo (MC) simulations of the expected PET signal at the start of treatment, and to study how the PET signal may change along the treatment course due to morphological changes. We performed voxel-wise two-tailed statistical tests of the simulated PET images, resembling the voxel-based morphometry (VBM) method commonly used in neuroimaging data analysis, to locate regions with significant morphological changes and to quantify the&nbsp;change. Results: The VBM resembling method has been successfully applied to the simulated in-beam PET images, despite the fact that such images suffer from image artifacts and limited statistics. Three dimensional probability maps were obtained, that allowed to identify interfractional morphological changes and to visualize them superimposed on the computed tomography (CT) scan. In particular, the characteristic color patterns resulting from the two-tailed statistical tests lend themselves to trigger alarms in case of morphological changes along the course of&nbsp;treatment. Conclusions: The statistical method presented in this work is a promising method to apply to PET monitoring data to reveal interfractional morphological changes in patients, occurring over the course of treatment. Based on simulated in-beam PET treatment monitoring images, we showed that with our method it was possible to correctly identify the regions that changed. Moreover we could quantify the changes, and visualize them superimposed on the CT scan. The proposed method can possibly help clinical personnel in the replanning procedure in adaptive proton therapy treatments
