[PREVALENCE OF PROBABLE DEPRESSION AND ANXIETY IN MEDICAL STUDENTS OF THE NATIONAL UNIVERSITY OF ROSARIO, ARGENTINA].

Introduction: Depression and anxiety affect students on an academic and personal level. Compared to the population, college stu-dents seem to show a higher prevalence of both disorders.

Objectives: To estimate the prevalence of anxiety and depression, and associated risk factors in a sample of medical students.

Testing a Novel 3D Printed Radiographic Imaging Device for Use in Forensic Odontology.

There are specific challenges related to forensic dental radiology and difficulties in aligning X-ray equipment to teeth of interest. Researchers used 3D printing to create a new device, the combined holding and aiming device (CHAD), to address the positioning limitations of current dental X-ray devices. Participants (N = 24) used the CHAD, soft dental wax, and a modified external aiming device (MEAD) to determine device preference, radiographer's efficiency, and technique errors.

How should I treat a complex Post-CABG patient?

Background: A 69 year old man was admitted with unstable angina (Class IIB). He had a history of chronic renal impairment, diabetes mellitus, hypertension and coronary bypass surgery in 1997 (LIMA graft to the LAD anf diagonal branch, saphenous vein grafts to the RCA and first marginal branch of LCx.

Investigation: Coronary angiography.

Early echocardiographic evaluation following percutaneous implantation with the self-expanding CoreValve Revalving System aortic valve bioprosthesis.

Aims: Although safety and feasibility studies have been published, there are few reports dedicated to the echocardiographic evaluation of patients following percutaneous aortic valve replacement (PAVR). This report describes the early echocardiographic evaluation of patients undergoing PAVR with the CoreValve Revalving System.

Methods And Results: The population consisted of 33 consecutive patients with aortic stenosis who underwent successful PAVR.

Aluminium sulfate as coagulant for highly polluted cork processing wastewaters: removal of organic matter.

This is the first part of a work on the chemistry of aluminium as coagulant in the treatment of highly polluted cork processing wastewater. The main aim of this first part was to determine the removal of organic matter - measured by reductions in chemical oxygen demand (COD), polyphenols (TP), and aromatic compounds (A) - that can be obtained using this physicochemical process. To this end, jar-test experiments were carried out to determine the optimal conditions for the process, in particular, the effective aluminium dosage, contamination level of wastewater, coagulant mixing time, stirring speed, and pH.

Aluminium sulfate as coagulant for highly polluted cork processing wastewater: Evaluation of settleability parameters and design of a clarifier-thickener unit.

This is the second part of a master project on the chemistry of aluminium as coagulant in the treatment of highly polluted cork-process-wastewater. The main aim of this second part was to determine the influence of the operating conditions on the system's settleability parameters. It is well known that it is just as important to achieve good settleability parameters in the physico-chemical treatment of wastewaters as it is to attain a high level of decontamination.

A simulation-based training system for surgical wound debridement.

A simulation-based training system for surgical wound debridement was developed and comprises a multimedia introduction, a surgical simulator (tutorial component), and an assessment component. The simulator includes two PCs, a haptic device, and mirrored display. Debridement is performed on a virtual leg model with a shallow laceration wound superimposed.

Medical student evaluation using augmented standardized patients: preliminary results.

Standardized patients (SPs), individuals trained to realistically portray patients, are commonly used to teach and assess medical students. The range of clinical problems an SP can portray, however, is limited. They are typically healthy individuals with few or no abnormal physical findings.
