Risks of hospitalization and drug consumption in children and young adults with diagnosed celiac disease and the role of maternal education: A population-based matched birth cohort study
Background: Celiac disease (CD) may affect healthcare use in children and young adults. Socio-economic factors
may act as a confounder or effect modifier. We assessed such hypotheses in a population-based birth cohort of
young celiac subjects and references matched by maternal education.
Methods: The cohort included all newborns recorded in the Medical Birth Register of Friuli-Venezia Giulia Region
(Italy) between 1989 and 2011. CD incident cases were identified through pathology reports, hospital discharges
and copayment exemptions and matched with up to five references by sex, year of birth and maternal education.
Cox regression models were used to estimate Hazard Ratios (HRs) for major causes of inpatient diagnosis and drug
prescription occurring after diagnosis in CD patients compared to references, stratifying by time of first event and
maternal education.
Results: We identified 1294 CD cases and 5681 references. CD cases had a higher risk of hospital admission for
any cause (HR: 2.34; 95 % CI 2.08-2.63) and for all major ICD9-CM categories except obstetric complications, skin
and musculoskeletal diseases, and injuries and poisoning. Prescription of all major ATC drug categories, except
dermatologicals and genito-urinary medications, was significantly increased in CD subjects. For most outcomes, HRs
were highest in the first year after CD diagnosis but remained significant after five or more years. HRs were similar
across different categories of maternal education.
Conclusions: Diagnosed CD subjects had a higher risk of hospitalization and medication use compared to the
general population, even five or more years after diagnosis, with no effect modification of maternal education
Identification of material properties and optimal design of magnetically shielded rooms
In this paper, we propose an optimal design procedure for magnetically shielded rooms. Focusing on multi-layer ferromagnetic structures, where inner layers operate at very low magnetic field, we propose an identification method of the magnetic material characteristic in the Rayleigh region. A numerical model to simulate the shielding efficiency of a multi-layer ferromagnetic structure is presented and experimentally tested on different geometries and layer configurations. The fixed point iterative method is adopted to handle the nonlinearity of the magnetic material. In conclusion, the optimization of the design parameters of a MSR is discussed, using the Vector Immune System algorithm to minimize the magnetic field inside the room and the cost of the structure. The results highlight that a linear magnetic characteristic for the material is sufficient to identify the suitable geometry of the shield, but the nonlinear model in the Rayleigh region is of fundamental importance to determine a realistic shielding factor
OpenCoesione and Monithon - a Transparency Effort
Context
OpenCoesione is the first portal about the fulfilment of investments and projects planned by the Italian central government and by the Italian Regions using the 2007Â2013 European Cohesion funds. Together with Monithon, it is a “transparency tool” whose aim is to foster participation of the citizens and efficiency of the public sector bodies in order to improve the implementation of development policies. By now it is one of the best Open Data portal in Italy qualityÂwise.
Objective
Our goal is to show the utility of these portals, how this open information is supposed to help the civil society and how data quality might affect reuse.
Method
We engage in the empirical observation on how data are exposed and used, discussing specific examples, and applying some data quality metrics.
Results
We present some evidences on how open data can positively affect the public sector bodies and the spending of funds.
Conclusions
UnderÂspending of EU Cohesion funds is a serious problem in Italy. OpenCoesione and Monithon can contribute solving this inefficiency, e.g., by presenting data in such a (standardised) way to enable their elaboration by third partie
