Requirements for applying a case-control study model and clinical significance of changes in the visual analogue scale score in abdominal pain
No full textThe framework of the study is a comparison of two
groups of patient: one group formed of people affected by
the pathological condition (cases) and the other constituted
by people with the same features as the cases but free from
the pathological condition to be analysed (controls). The
crucial aspect of the design of a case–control study is that
the cases are correctly selected, since the reliability of the
study itself depends on this

No full textThe comparison between the old techniques and the new one (LG and LP versus Direct) showed a lower incidence of complications among the animals that underwent the new direct technique (P < 0.05). This technique could be applied clinically in selected pediatric cases either of transplantation or reflux

No full textNowadays, most medical-diagnostic, environmental monitoring, etc. devices employ sensors whose fabrication reproducibility and response repeatability assessment are crucial. The former consists of large-scale sensor manufacture through a standardized process with almost identical morphology and behavior, while the latter consists of giving the same response upon repeating the same stimulus. The thermo-activated chemoresistive sensors, which change their conductance by interacting with the molecules composing the surrounding gas, are currently employed in many devices: in particular, thick-film (SnTiNb)O2 nanosensors were demonstrated to be particularly suitable in the medical and biological fields. Therefore, a set of thirteen of them, randomly selected from the same screen-printing deposition, were laboratory tested, and the outcomes were statistically analyzed in order to assess their consistency. At first, the working temperature that maximized both the sensor sensitivity and response repeatability was identified. Then, the sensors were subjected to different gas concentrations and humidities at this optimal working temperature. It resulted in the (SnTiNb)O2 nanosensors detecting and discriminating CO concentrations as low as 1 ppm and at high humidity degrees (up to 40%) with high repeatability since the response relative standard error ranged from 0.8 to 3.3% for CO and from 3.6 to 5.4% for water vapor
