    Through the conceptual framework of datafication, dataism and dataveillance, this study investigates beliefs and attitudes regarding datafication and the related privacy and security concerns among individuals with Type 1 diabetes. Qualitative research was conducted through interviews among fifty-two individuals with Type 1 diabetes in Poland and Italy. The findings reveal a dynamic interplay between self-discipline and empowerment. The majority of interviewees emphasized the benefits of technologies for gaining a better understanding of their health condition and for more effective disease management. However, a minority of interviewees perceived the negative effects of datafication, including dataveillance, which leads to hyper-control of the disease, and dataism, characterized by excessive reliance on and dependency on technology. Critical beliefs about technologies fuelled rejection attitudes, leading some interviewees to suspend or abandon their use. Lastly, reflexivity on privacy and security issues appears to be low, particularly among older individuals with lower levels of education and socioeconomic status. This results in a poor understanding and underestimation of the potential risks associated with security and privacy. The findings increase the understanding of the factors that can facilitate or hinder the adoption of technology among people with diabetes

    Le migrazioni ambientali e al femminile in prospettiva sociologica. Istanze di sostenibilità, diritti e vulnerabilità delle donne migranti

    Get PDF
    Le migrazioni ambientali rivestono un grande interesse negli studi sociologici nell’inquadramento delle cause e dei fattori di spinta (push factors) che le determinano, di tipo climatico e ambientale, insieme alle diverse spiegazioni teoriche di tipo macro, micro e mesosociologico che la disciplina applica allo studio delle migrazioni. Allo stesso tempo, negli ultimi anni, le migrazioni al femminile hanno ricevuto un’ampia attenzione a seguito dell’incremento sostanziale della componente femminile, anche primo-migrante, che intraprende un progetto migratorio in prospettiva individuale e/ o familiare. Interessante è, da questo punto di vista, l’articolazione delle questioni di genere e dei diritti di genere a esse legati intorno agli obiettivi dell’Agenda 2030 dell’ONU, che ben intersecano la condizione femminile alle istanze di sviluppo sostenibile, collegando i diritti fondamentali (istruzione, nutrizione, accesso alle risorse primarie, lavoro) al miglioramento delle condizioni di vita nei paesi svantaggiati e nei percorsi migranti. Il contributo propone una rassegna delle principali teorie che spiegano le migrazioni al femminile, nello specifico, nel novero delle migrazioni ambientali al fine di integrare in prospettiva sociologica lo studio di un fenomeno contemporaneo complesso e di grande rilievo sul piano analitico. A ciò si coniuga una discussione di matrice socio-giuridica introno alle dimensioni normative che possono incidere sulle pratiche dell’inclusione o dell’esclusione di una categoria sociale particolarmente esposta alla vulnerabilità.Environmental migrations are of great interest in sociological studies in the framing of their climatic and environmental causes and push factors, of climatic and environmental kind, along with the various macro, micro, and meso-sociological theoretical explanations that the discipline applies to the study of migrations. At the same time, in recent years female migrations have received wide attention following the significant increase in the female component, even the early migrant who undertakes a migration project from an individual and/or family perspective. Interesting, from this point of view, is the articulation of gender issues and related gender rights around the UN Agenda 2030 goals, which well intersect the status of women with instances of sustainable development, linking fundamental rights (education, nutrition, access to primary resources, employment) to improving living conditions in disadvantaged countries and migrant pathways. The essay proposes a review of the main theories that explain female migrations, specifically environmental migrations, in order to integrate the study of a complex contemporary phenomenon of great analytical importance in a sociological perspective. This is coupled with a socio-legal discussion about the normative dimensions that may affect the practices of inclusion or exclusion of a social category particularly exposed to vulnerability

    Increased cancer risk in patients undergoing dialysis: a population-based cohort study in North-Eastern Italy

    open116noBACKGROUND: In southern Europe, the risk of cancer in patients with end-stage kidney disease receiving dialysis has not been well quantified. The aim of this study was to assess the overall pattern of risk for de novo malignancies (DNMs) among dialysis patients in the Friuli Venezia Giulia region, north-eastern Italy. METHODS: A population-based cohort study among 3407 dialysis patients was conducted through a record linkage between local healthcare databases and the cancer registry (1998-2013). Person-years (PYs) were calculated from 30 days after the date of first dialysis to the date of DNM diagnosis, kidney transplant, death, last follow-up or December 31, 2013, whichever came first. The risk of DNM, as compared to the general population, was estimated using standardized incidence ratios (SIRs) and 95% confidence intervals (CIs). RESULTS: During 10,798 PYs, 357 DNMs were diagnosed in 330 dialysis patients. A higher than expected risk of 1.3-fold was found for all DNMs combined (95% CI: 1.15-1.43). The risk was particularly high in younger dialysis patients (SIR = 1.88, 95% CI: 1.42-2.45 for age 40-59 years), and it decreased with age. Moreover, significantly increased DNM risks emerged during the first 3 years since dialysis initiation, especially within the first year (SIR = 8.52, 95% CI: 6.89-10.41). Elevated excess risks were observed for kidney (SIR = 3.18; 95% CI: 2.06-4.69), skin non-melanoma (SIR = 1.81, 95% CI: 1.46-2.22), oral cavity (SIR = 2.42, 95% CI: 1.36-4.00), and Kaposi's sarcoma (SIR = 10.29, 95% CI: 1.25-37.16). CONCLUSIONS: The elevated risk for DNM herein documented suggest the need to implement a targeted approach to cancer prevention and control in dialysis patients.openTaborelli, Martina; Toffolutti, Federica; Del Zotto, Stefania; Clagnan, Elena; Furian, Lucrezia; Piselli, Pierluca; Citterio, Franco; Zanier, Loris; Boscutti, Giuliano; Serraino, Diego for the Italian Transplant & Cancer Cohort Study; Sarah Shalaby, Raffaella Petrara, Patrizia Burra, Giacomo Zanus, Stefano Zanini,Paolo Rigotti; Maria Rendina, AlfredoDi Leo, Francesco Paolo Schena, Giuseppe Grandaliano, Marco Fiorentino, Augusto Lauro, Antonio Daniele Pinna, PaoloDi Gioia, Sara Pellegrini, Chiara Zanfi, Maria Piera Scolari, Sergio Stefoni, PaolaTodeschini, Laura Panicali, Chiara Valentini, Umberto Baccarani, Andrea Risaliti, Gian Luigi Adani, Dario Lorenzin, Giuseppe Maria Ettorre, Giovanni Vennarecci,Marco Colasanti, Manuela Coco, Fabrizio Ettorre, Roberto Santoro, LuciaMiglioresi, Francesco Nudo, Massimo Rossi,Gianluca Mennini, Luca Toti, GiuseppeTisone, Annachiara Casella, Laura Fazzolari, Daniele Sforza, Giuseppe Iaria,Carlo Gazia, Chiara Belardi, ClaudiaCimaglia, Alessandro Agresta, Gianpiero D’Offizi, Ubaldo Visco Comandini,Raffaella Lionetti, Marzia Montalbano, Chiara Taibi, Giovanni Fantola, Fausto Zamboni, Gian Benedetto Piredda,Maria Benigna Michittu, Maria Gavina Murgia, Bruno Onano, Lucia Fratino, Luigino Dal Maso, Paolo De Paoli, Diana Verdirosi,Emanuela Vaccher, Francesco Pisani, Antonio Famulari, Federica Delreno, Samuele Iesari, LindaDe Luca, Maurizio Iaria, Enzo Capocasale,Elena Cremaschi, Silvio Sandrini, Francesca Valerio,Valentina Mazzucotelli, Nicola Bossini, Gisella Setti, Massimiliano Veroux, Pierfrancesco Veroux, Giuseppe Giuffrida,Alessia Giaquinta, Domenico Zerbo, GhilBusnach, Laura Di Leo, Maria Luisa Perrino, Marialuisa Querques, ValerianaColombo, Maria Chiara Sghirlanzoni , Piergiorgio Messa, Antonio Leoni , Laura Galatioto, Salvatore Gruttadauria, Vito Sparacino, FlaviaCaputo, Barbara Buscemi ,Franco Cit-terio, Gionata Spagnoletti, Maria Paola Salerno, Evaldo Favi Giuseppe Paolo Segoloni, Luigi Biancone, AntonioLavacca, Maria Cristina Maresca, CarmeloCascone, Bice Virgilio, Donato Donati, Fiorella Dossi, Andrea Fontanella, Andrea Ambrosini, Marco Di CiccoTaborelli, Martina; Toffolutti, Federica; Del Zotto, Stefania; Clagnan, Elena; Furian, Lucrezia; Piselli, Pierluca; Citterio, Franco; Zanier, Loris; Boscutti, Giuliano; Serraino, Diego for the Italian Transplant & Cancer Cohort Study; Shalaby, Sarah; Petrara, MARIA RAFFAELLA; Burra, Patrizia; Zanus, Giacomo; Zanini, Stefano; Rigotti, Paolo; Maria, Rendina; Alfredodi, Leo; Francesco Paolo Schena, ; Giuseppe, Grandaliano; Marco, Fiorentino; Augusto, Lauro; Antonio Daniele Pinna, ; Paolodi, Gioia; Sara, Pellegrini; Chiara, Zanfi; Maria Piera Scolari, ; Sergio, Stefoni; Paolatodeschini, ; Laura, Panicali; Chiara, Valentini; Umberto, Baccarani; Andrea, Risaliti; Gian Luigi Adani, ; Dario, Lorenzin; Giuseppe Maria Ettorre, ; Giovanni, Vennarecci; Marco, Colasanti; Manuela, Coco; Fabrizio, Ettorre; Roberto, Santoro; Luciamiglioresi, ; Francesco, Nudo; Massimo, Rossi; Gianluca, Mennini; Luca, Toti; Giuseppetisone, ; Annachiara, Casella; Laura, Fazzolari; Daniele, Sforza; Giuseppe, Iaria; Carlo, Gazia; Chiara, Belardi; Claudiacimaglia, ; Alessandro, Agresta; Gianpiero, D’Offizi; Ubaldo Visco Comandini, ; Raffaella, Lionetti; Marzia, Montalbano; Chiara, Taibi; Giovanni, Fantola; Fausto, Zamboni; Gian Benedetto Piredda, ; Maria Benigna Michittu, ; Maria Gavina Murgia, ; Bruno, Onano; Lucia, Fratino; Luigino Dal Maso, ; Paolo De Paoli, ; Diana, Verdirosi; Emanuela, Vaccher; Francesco, Pisani; Antonio, Famulari; Federica, Delreno; Samuele, Iesari; Lindade, Luca; Maurizio, Iaria; Enzo, Capocasale; Elena, Cremaschi; Silvio, Sandrini; Francesca, Valerio; Valentina, Mazzucotelli; Nicola, Bossini; Gisella, Setti; Massimiliano, Veroux; Pierfrancesco, Veroux; Giuseppe, Giuffrida; Alessia, Giaquinta; Domenico, Zerbo; Ghilbusnach, ; Laura Di Leo, ; Maria Luisa Perrino, ; Marialuisa, Querques; Valerianacolombo, ; Maria Chiara Sghirlanzoni, ; Piergiorgio, Messa; Antonio, Leoni; Laura, Galatioto; Salvatore, Gruttadauria; Vito, Sparacino; Flaviacaputo, ; Barbara, Buscemi; Franco, Cit-terio; Gionata, Spagnoletti; Maria Paola Salerno, ; Evaldo Favi Giuseppe Paolo Segoloni, ; Luigi, Biancone; Antoniolavacca, ; Maria Cristina Maresca, ; Carmelocascone, ; Bice, Virgilio; Donato, Donati; Fiorella, Dossi; Andrea, Fontanella; Andrea, Ambrosini; Marco Di Cicco

    Accuracy of intracranial pressure monitoring : systematic review and meta-analysis

    Get PDF
    Introduction: Intracranial pressure (ICP) measurement is used to tailor interventions and to assist in formulating the prognosis for traumatic brain injury patients. Accurate data are therefore essential. The aim of this study was to verify the accuracy of ICP monitoring systems on the basis of a literature review. Methods: A PubMed search was conducted from 1982 to 2014, plus additional references from the selected papers. Accuracy was defined as the degree of correspondence between the pressure read by the catheter and a reference "real" ICP measurement. Studies comparing simultaneous readings from at least two catheters were included. Drift was defined as the loss of accuracy over the monitoring period. Meta-analyses of data from the studies were used to estimate the overall mean difference between simultaneous ICP measurements and their variability. Individual studies were weighted using both a fixed and a random effects model. Results: Of 163 articles screened, 83 compared two intracranial catheters: 64 reported accuracy and 37 drift(some reported both). Of these, 10 and 17, respectively, fulfilled the inclusion criteria for accuracy and zero drift analysis. The combined mean differences between probes were 1.5mmHg (95% confidence interval (CI) 0.7-2.3) with the random effects model and 1.6mmHg (95% CI 1.3-1.9) with the fixed effects model. The reported mean drift over a long observation period was 0.75mmHg. No relation was found with the duration of monitoring or differences between various probes. Conclusions: This study confirms that the average error between ICP measures is clinically negligible. The random effects model, however, indicates that a high percentage of readings may vary over a wide range, with clinical implications both for future comparison studies and for daily care

    Label-free monitoring of tissue biochemistry following traumatic brain injury using Raman spectroscopy.

    Traumatic brain injury (TBI) constitutes a major cause of death and long-term disability. At present, we lack methods to non-invasively track tissue biochemistry and hence select appropriate interventions for patients. We hypothesized that detailed label-free vibrational chemical analysis of focal TBI could provide such information. We assessed the early spatial and temporal changes in tissue biochemistry that are associated with brain injury in mice. Numerous differences were observed in the spectra of the contusion core and pericontusional tissue between 2 and 7 days. For example, a strong signal from haem was seen in the contusion core at 2 days due to haemorrhage, which subsequently resolved. More importantly, elevated cholesterol levels were demonstrated by 7 days, which may be a marker of important cell repair processes. Principal component analysis revealed an early 'acute' component dominated by haemorrhage and a delayed component reflecting changes in protein and lipid composition. Notably we demonstrated changes in Raman signature with time even in the contralateral hemisphere when compared to sham control mice. Raman spectroscopy therefore shows promise as a probe that is sensitive to important pathobiological processes in TBI and could be applied in future both in the experimental setting, as well as in the clinic

    Intracranial pressure after subarachnoid hemorrhage

    Get PDF
    Objectives: To describe mean intracranial pressure after aneurysmal subarachnoid hemorrhage, to identify clinical factors associated with increased mean intracranial pressure, and to explore the relationship between mean intracranial pressure and outcome. Design: Analysis of a prospectively collected observational database. Setting: Neuroscience ICU of an academic hospital. Patients: One hundred sixteen patients with subarachnoid hemorrhage and intracranial pressure monitoring. Interventions: None. Measurements and Main Results: Episodes of intracranial pressure greater than 20 mm Hg lasting at least 5 minutes and the mean intracranial pressure for every 12-hour interval were analyzed. The highest mean intracranial pressure was analyzed in relation to demographic characteristics, acute neurologic status, initial radiological findings, aneurysm treatment, clinical vasospasm, and ischemic lesion. Mortality and 6-month outcome (evaluated using a dichotomized Glasgow Outcome Scale) were also introduced in multivariable logistic models. Eighty-one percent of patients had at least one episode of high intracranial pressure and 36% had a highest mean intracranial pressure more than 20 mm Hg. The number of patients with high intracranial pressure peaked 3 days after subarachnoid hemorrhage and declined after day 7. Highest mean intracranial pressure greater than 20 mm Hg was significantly associated with initial neurologic status, aneurysmal rebleeding, amount of blood on CT scan, and ischemic lesion within 72 hours from subarachnoid hemorrhage. Patients with highest mean intracranial pressure greater than 20 mm Hg had significantly higher mortality. When death, vegetative state, and severe disability at 6 months were pooled, however, intracranial pressure was not an independent predictor of unfavorable outcome. Conclusions: High intracranial pressure is a common complication in the first week after subarachnoid hemorrhage in severe cases admitted to ICU. Mean intracranial pressure is associated with the severity of early brain injury and with mortality

    Brain oxygen tension, oxygen supply, and oxygen consumption during arterial hyperoxia in a model of progressive cerebral ischemia

    Get PDF
    We investigated the changes in brain oxygen tension (ptiO(2)) after ventilation with pure O-2 in order to (1) clarify the pathophysiology of O-2 exchange in the cerebral microcirculation; and (2) investigate the relationship between brain O-2 tension, O-2 delivery, and consumption in steady-state conditions during stepwise cerebral blood flow (CBF) reductions. A swine model was developed to reduce CBF in three stable steps: (1) baseline (CBF 100%), (2) CBF of 50-60% of baseline, and (3) CBF of (30% of baseline. CBF was reduced by infusing saline into the left lateral ventricle through a catheter connected with an infusion pump. At each step, hyperoxia was tested by increasing the inspired oxygen fraction up to 100%, PtiO(2) reflected the CBF reductions, since it was respectively 27.95 ( +/-10.15), 14.77 (+/-3.58), and 3.45 (+/-2.89) mm Hg during the three CBF steps. Hyperoxia was followed by an increase in ptiO(2), although the increase was significantly lower when hyperoxia was applied during progressive ischemia. O-2 supply to the brain did not change during hyperoxia. Arteriovenous oxygen difference (AVDO(2)) decreased during the phases of intact CBF and moderate impairment, but not during the phase of severe CBF reduction. In conclusion, ptiO(2) reductions closely reflect the imbalance between oxygen delivery and demand; this implies a link between low ptiO(2) and defective O-2 supply due to impaired CBF. However, this relation is not necessarily reciprocal, since manipulating brain oxygen tension does not always influence brain oxygen delivery, as in the case of ventilation with pure oxygen

    Mineralogical evolution of cement pastes at early ages based on thermogravimetric analysis (TGA)

    Full text link
    [EN] Ordinary thermogravimetric analysis (TG) and high-resolution TG tests were carried out on three different Portland cement pastes to study the phases present during the first day of hydration. Tests were run at 1, 6, 12 and 24 h of hydration, in order to determine the phases at these ages. High-resolution TG tests were used to separate decompositions presented in the 100¿200 C interval. The non-evaporable water determined by TG was used to determine hydration degree for the different ages. The effect of particle size distribution (PSD) on mineralogical evolution was established, as well as the addition of calcite as mineralogical filler. Finer PSD and calcite addition accelerate the hydration process, increasing the hydration degree on the first day of eaction between water and cement. According to high-resolution TG results, it was demonstrated that ettringite was the only decomposed phase in the 100¿200 C interval during the first 6 h of hydration for all studied cements. C-S-H phase starts to appear in all cements after 12 h of hydration.Funding was provided by Colciencias (Grant No. Convocatoria 567-2012).Gaviria, X.; Borrachero Rosado, MV.; Paya Bernabeu, JJ.; Monzó Balbuena, JM.; Tobón, J.
