    Background: Breast Cancer susceptibility genes 1 and 2 are implicated in hereditary breast and ovarian cancer and women can test for the presence of these genes prior to developing cancer. The goal of this study is to examine psychological distress, quality of life, and active coping mechanisms in a sample of women during the pre-test stage of the genetic counseling process, considering that pre-test distress can be an indicator of post-test distress. We also wanted to identify if subgroups of women, defined based on their health status, were more vulnerable to developing distress during the genetic counseling process.Methods: This study included 181 female participants who accessed a Cancer Genetic Counseling Clinic. The participants were subdivided into three groups on the basis of the presence of a cancer diagnosis: Affected patients, Ex-patients, and Unaffected participants. Following a self-report questionnaire, a battery of tests was administered to examine psychological symptomatology, quality of life, and coping mechanisms.Results: The results confirm that the genetic counseling procedure is not a source of psychological distress. Certain participants were identified as being more vulnerable than others; in the pre-test phase, they reported on average higher levels of distress and lower quality of life. These participants were predominantly Ex-patients and Affected patients, who may be at risk of distress during the counseling process.Conclusions: These findings highlight that individuals who take part in the genetic counseling process are not all the same regarding pre-test psychological distress. Attention should be paid particularly to Ex-patients and Affected patients by the multidisciplinary treating team

    Mesenchymal inflammation drives genotoxic stress in hematopoietic stem cells and predicts disease evolution in human pre-leukemia

    Mesenchymal niche cells may drive tissue failure and malignant transformation in the hematopoietic system but the molecular mechanisms and their relevance to human disease remain poorly defined. Here, we show that perturbation of mesenchymal cells in a mouse model of the preleukemic disorder Shwachman-Diamond syndrome induces mitochondrial dysfunction, oxidative stress and activation of DNA damage responses in hematopoietic stem and progenitor cells. Massive parallel RNA sequencing of highly purified mesenchymal cells in the mouse model and a range of human preleukemic syndromes identified p53-S100A8/9-TLR inflammatory signaling as a common driving mechanism of genotoxic stress. Transcriptional activation of this signaling axis in the mesenchymal niche predicted leukemic evolution and progression-free survival in myelodysplastic syndrome, the principal leukemia predisposition syndrome. Collectively, our findings reveal a concept of mesenchymal niche-induced genotoxic stress in heterotypic stem and progenitor cells through inflammatory signaling as an actionable determinant of disease outcome in human preleukemia

    The adoption of Internet of Things and Cloud technologies in the context of Industry 4.0 provides manufacturing industries with the opportunity to collect data from multiple sources. Analytical tools and techniques can be then applied to support decision-making processes with valuable information. Industry 4.0 technologies have been implemented in many sectors and industries: among them, energy management - often representing one of the main costs for manufacturing companies - is considered in this study. The aim of this paper is to contribute to the understanding of how the implementation of Industry 4.0 technologies and, in particular, the analysis of energy consumption data, can change or enable decision-making thereby improving energy management. Based on a literature review and current practices, possible applications of data analytics in the energy management field are proposed and several energy management decision areas are discussed. The paper includes a case study aiming at illustrating how the implementation of Industry 4.0 technologies, supported by proper strategical and operational approaches can improve energy management integrating energy consumption data with other sources of data

    Exome sequencing and pathway analysis for identification of genetic variability relevant for bronchopulmonary dysplasia (BPD) in preterm newborns: A pilot study

    Background: Bronchopulmonary dysplasia (BPD) is the most common chronic lung disease in infancy, affecting preterm children with low birth weight. The disease has a multifactorial aetiology with a significant genetic component; until now published association studies have identified several candidate genes but only few of these data has been replicated. In this pilot study, we approached exome sequencing aimed at identifying non-common variants, which are expected to have a stronger phenotypic effect. Materials and methods: We performed this study on 26 Italian severely affected BPD preterm unrelated newborns, homogeneously selected from a large prospective cohort. We used an Illumina HiSeq 2000 for sequencing. Data analysis was focussed on genes previously associated to BPD susceptibility and to new candidates in related pathways, highlighted by a prioritization analysis performed using ToppGene Suite. Results: By exome sequencing, we identified 3369 novel variants, with a median of 400 variations per sample. The top candidate genes highlighted were NOS2, MMP1, CRP, LBP and the toll-like receptor (. TLR) family. All of them have been confirmed with Sanger sequencing. Conclusions: Potential candidate genes have been discovered in this preliminary study; the pathogenic role of identified variants will need to be confirmed with functional and segregation studies and possibly with further methods, able to evaluate the collective influence of rare variants.Moreover, additional candidates will be tested and genetic analysis will be extended to all affected children

    OBJECTIVES: We compared the relative effect of hypertensive disorders of pregnancy and chorioamnionitis on adverse neonatal outcomes in very preterm neonates, and studied whether gestational age (GA) modulates these effects. METHODS: A cohort of neonates 23 to 30 weeks' GA, born in 2008 to 2011 in 82 hospitals adhering to the Italian Neonatal Network, was analyzed. Infants born from mothers who had hypertensive disorders (N = 2096) were compared with those born after chorioamnionitis (N = 1510). Statistical analysis employed logistic models, adjusting for GA, hospital, and potential confounders. RESULTS: Overall mortality was higher after hypertension than after chorioamnionitis (odds ratio [OR], 1.39; 95% confidence interval [CI], 1.08-1.80), but this relationship changed across GA weeks; the OR for hypertension was highest at low GA, whereas from 28 weeks' GA onward, mortality was higher for chorioamnionitis. For other outcomes, the relative risks were constant across GA; infants born after hypertension had an increased risk for bronchopulmonary dysplasia (OR, 2.20; 95% CI, 1.68-2.88) and severe retinopathy of prematurity (OR, 1.48; 95% CI, 1.02-2.15), whereas there was a lower risk for early-onset sepsis (OR, 0.25; 95% CI, 0.19-0.34), severe intraventricular hemorrhage (OR, 0.65; 95% CI, 0.48-0.88), periventricular leukomalacia (OR, 0.70; 95% CI, 0.48-1.01), and surgical necrotizing enterocolitis or gastrointestinal perforation (OR, 0.47; 95% CI, 0.31-0.72). CONCLUSIONS: Mortality and other adverse outcomes in very preterm infants depend on antecedents of preterm birth. Hypertension and chorioamnionitis are associated with different patterns of outcomes; for mortality, the effect changes across GA weeks. Copyright \uc2\ua9 2014 by the American Academy of Pediatrics
