Gestational diabetes: universal or selective screening?
No full textTo evaluate the incidence of gestational diabetes in our population and verify costs of universal screening. To assess neonatal and obstetrical outcomes with respect to maternal epidemiological characteristics.
METHODS:
Eight hundred and fifty-six pregnant women between 24th and 28th weeks of gestation were examined in this observational study. Universal screening with glucose challenge test was used to screen the group for gestational diabetes. History, obstetrical and neonatal outcomes were collected and then analyzed.
RESULTS:
Gestational diabetes was diagnosed in 6.6% of cases. Patients with at least one risk factor had a cesarean section in 50% of cases and a spontaneous vaginal delivery in 23.59% of cases (p < 0.001). The absence of any risk factor was found in 73.7% of positive glucose tolerance test and in 62.5% of affected patients. The cost of universal screening in our study, was 57,60 Euros per case identified.
CONCLUSIONS:
Given the high prevalence of diabetes, the high proportion of patients potentially not identified with a selective screening in this study and the relatively low cost, universal screening for gestational diabetes seems the best way to identify patients and prevent adverse obstetrical and neonatal outcomes

No full textIn the field of Cryptography, Quantum Key Distribution (QKD) is an application of Quantum Information theory that obtained a
great deal of attention in recent years. It allows to establish secret keys between two or more parties, in a much safer way than that implemented
by classic cryptography (based on discrete logarithms and factorization of prime numbers). The most promising way of realizing
a QKD network (especially over great distances) in the near future is by a constellation of satellites. This paper considers the problem of
optimizing the orbits of the satellites in order to maximize the minimum key length shared in a network of ground stations over a fixed
amount of time. Different networks of stations are considered and the influence of their geographical disposition on the design and the
performance index is highlighted. The networks considered are: a global constellation, a regional European constellation, and two in
which there are groups of stations in two different narrow bands of latitude. The effect of Inter-satellite links is then taken into account
and how, in some cases, they can improve the performances. Finally the daily performance of the considered constellations are analyzed
