COMMUNICATIONSTO THE EDITOR 551 arteriovenous oxygen content difference (C[a-v]02) equals 3; and the fractional concentration of oxygen in the inspired gas (F1o2) equals 0.40. From the oxyhemoglobin dissociation curve, the arterial oxygen saturation equals 0.90. Since C(a-v)O, equals 3, the venous oxygen saturation (Sv02) equals 0.75 approximately. Using these figures, the QS/QT equals 0.502. T...

Consider a binary classification prediction problem. Training data are given and we denote them observations as T = {X,y} = {xi, yi}i=1, where xi ∈ R, yi ∈ {+1,−1} (accordingly X ∈ Rm×n). First, we will consider the case where the two classes are linearly separable. That is, by an n-dimensional decision boundary which is the result of an n + 1-dimensional hyperplane). Furthermore, since there c...

Introduction: performing anal endosonography in complex fistula-in-ano allows us to design a personalized surgical strategy in each case, thereby improving results. However, there are doubts in the literature as to its utility in recurrent complex fistulas. The aim of this study was to compare the utility of anal ultrasonography in the study of primary versus recurrent complex fistula-inano. Pa...

This study explores the prevalence of criminal behaviour in patients addicted to drugs who are in treatment. A sample of 252 addicted patients (203 male and 49 female) who sought outpatient treatment at a specialized centre was assessed. Information on criminal behaviours, socio-demographic factors, consumption factors (assessed by the EuropAsi), psychopathological factors (assessed by SCL-90-R...
