All the male students in a high school in Brescia, North Italy (about 195,000 inhabitants) in Grades 9 through 13 were given a self-administered anonymous questionnaire during school time. Among the 1,462 students who filled in a valid questionnaire, 29.1% claimed to practice one or more sports regularly (at least 4 hours/week for 9 months/year or more), 30.2% practice sports occasionally, and 40.7% no sports at all. The percentage of current smokers (at least one cigarette a month) increased from 9th grade (11.1%) to 10th (13.2%), 11th (15.2%), 12th (27.7%), and 13th (23.7%) grade. The percentage of smokers showed a steady linear increase from the lowest to the highest grade in students practicing no or occasional activity but no increase in those who regularly practice sports. Students' smoking was negatively associated with the regular practice of sports among 12th-13th grade students.
In contrast with transthoracic echocardiography, transesophageal echocardiography provides a sure way to make the diagnosis of sinus venosus atrial septal defect; on the other hand this abnormality is more complex than that seen with the secundum atrial septal defect, and inexperienced operators may fail to recognize properly the defect. In front of a high reported sensitivity using transesophageal echocardiography, specificity is difficult to assess, due to possible underreporting of diagnostic errors. We describe a false positive diagnosis of sinus venosus atrial septal defect, in the setting of enlarged right chambers of the heart because of pressure overload. Modified anatomy of the heart, together with the presence of a prominent linear structure(probably Eustachian Valve) and an incomplete examination in this case made image interpretation very prone to misinterpretation. In this anatomical setting transesophageal longitudinal "bicaval" view may be sub-optimal for examining the atrial septum, potentially showing false images that need to be known for correct image interpretation. Nonetheless, a scan plane taken more accurately at the superior level would have demonstrated/excluded the pathognomonic feature of sinus venosus atrial septal defect in the high atrial septum, between the fatty limbus and the inferior aspect of the right pulmonary artery; moreover TEE allows morphological information about the posterior structures of the heart that need to be investigated in detail for a complete diagnosis.
ECG computerized analysis nowadays needs homogeneous standardized reading protocol to provide clinicians reliable diagnostic and prognostic help and allow communication between diflerent cardiological hosts and between cardiological intensive care units homes, ambulances or peripheral medical ettiergency structures.SCP protocol of the OEDlPE project solved many of these problems.In the past few years we have developed a proto!vpe expert system called ERIC for diagnostic and prognostic use in patients with chest pain so as to overcome many intrinsic limitations of ECG.The system utilizes for these purposes not only ECG analysis acoording to SCP-protocol criteria , but also chest pain characteristics analysis and risk projle estimation. Thanks to this data integration, the system is more accurate than ECG alone in the diagnosis of chest pain in both normal and diseased patients
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
