Medical Students' Attitude Toward Organ Donation: Understanding Reasons for Refusal in Order to Increase Transplantation Rates.

Objectives: To assess, among medical students, the willingness to donate their own organs or those of a family member, and to establish reasons for refusal.

Materials And Methods: During the 2016 academic year, an anonymous survey was conducted among University of Buenos Aires School of Medicine second-year students.

Results: Of the total 1012 respondents, 81.

[Generalized secondary peritonitis: predictors of in-hospital mortality and survival and mortality evolutive links].

Background: The knowledge of mortality predictors and evolutive variables linked with in-hospital death can help us to optimize corrective procedures.

Objectives: To identify independent predictors of in-hospital mortality and survival, and independent evolutive links with death in patients with generalized secondary peritonitis (GSP).

Methods: Two hundred and forty-two patients admitted into the hospital due to GSP were followed until in-hospital death or hospital discharge.

[Mediastinis related to esophagogastric disease and injury. Warning clinical signs and independent predictors of intrahospitalary survival].

Objective: To identify clinical warning signs and independent predictors of survival in mediastinitis related to esophagogastric diseases and injuries.

Methods: From March 1998 to February 2009, 36 patients with a mean age of 55.7 +/- 12.

[Predictors of intrahospitalary mortality in the upper gastrointestinal variceal bleeding due to chronic liver disease treated endoscopically].

Unlabelled: Upper gastrointestinal variceal bleeding is one of the most serious complications in patients with chronic liver disease. The aim of this trial is to identify in hospital mortality predictors in this illness.

Material And Methods: 106 hospitalizations due to this disease from October 2001 to April 2006 in cohort design.

Efficacy of octreotide and sclerotherapy in the treatment of acute variceal bleeding in cirrhotic patients. A prospective, multicentric, and randomized clinical trial.

Background: Sclerotherapy is the most widely used method for treatment of acute variceal bleeding. Previous reports have suggested that octreotide infusion is as effective as sclerotherapy. Our aim was to investigate the efficacy and safety of octreotide in comparison with sclerotherapy in controlling variceal bleeding.

Dextran administration avoids hemodynamic changes following paracentesis in cirrhotic patients. A safe and inexpensive option.

Paracentesis associated with albumin administration has been shown to be a safe and useful procedure in the treatment of patients with cirrhosis and ascites. Given the high cost of albumin, 20 patients with cirrhosis and ascites were treated in an open study, with daily paracentesis using dextran 70, an inexpensive volume expander, instead of albumin. In the first 10 patients, hemodynamic evaluation was performed in basal conditions, after each paracentesis (5 liter), and after dextran infusion.

Effects of diet composition on the metabolic and heart rate responses to cold water exposure in men.

The reaction to immersion in cold water (22 degrees C) was studied in ten healthy male volunteers successively receiving balanced (C), hypercarbohydrate (HC), hyperprotein (HP), and hyperlipid (HL) normocaloric diets with a three week equilibration period on each diet. Oxygen consumption (ml min-1 m-2) increased from 149 to 224 during C, from 160 to 196 during HL, from 154 to 178 during HP, and from 166 to 187 during HL. Only the first two differences were significant.
