[Implementation of a clinical prediction tool in renal transplant recipients].

Background: Kasiske developed a tool for predicting the risk of 5-year graft loss. We analyzed our results using this model.

Methods: 109 deceased donor kidney transplants were included.

[Diet and polymer standard vs. standard in the nutritional status of elderly patients with fragility].

Background: The elderly patients with fragility show different physiological changes, so they are given polymeric diets to maintain and/or alter their nutritional status. The aim of this paper is to demonstrate the effect of changing a standard polymeric diet and a standard diet on nutritional status in elderly patients with fragility.

Methods: Clinical randomized controlled trial in 23 elderly patients, 70 years of age or older, with fragility, hospitalized in a Internal Medicine Unity in a period from July to December 2014.

[Lactate levels as a predictor of mortality in patients with septic shock].

Background: The objective was to determine the association between serum lactate levels and mortality in patients with septic shock in the Emergency Room of the Instituto Mexicano del Seguro Social's Centro Médico Nacional Adolfo Ruiz Cortines.

Methods: We included the patients admitted to the Emergency Room with diagnosis of septic shock who had measure of serum lactate at admission during the period 01-12/2013; it was a case-control study. The cut-off value of serum lactate associated with mortality was performed using the ROC (receiver operating characteristic) curves.

Evaluation of previous abdominal pain episodes in women with biliary pancreatitis: possible higher incidence of recurrent attacks.

Background And Aim: Recurrent biliary pancreatitis is described as episodes of new abdominal pain after diagnosis of pancreatitis. Few studies have analyzed the abdominal pain before the diagnosis of acute pancreatitis. Our study aimed to analyze factors associated with previous abdominal pain episodes in patients with biliary pancreatitis, and elucidate its possible pancreatic origin.

Factors associated with early peritoneal dialysis catheter replacement in Veracruz, Mexico.

Introduction: Catheter-related complications in patients on peritoneal dialysis lead to decreased effectiveness and discontinuation of the technique, conversion to haemodialysis, hospitalisation, and surgical interventions to replace the catheter.

Objectives: Determine risk factors for early catheter dysfunction that result in the need for replacement.

Methods: We analysed 235 catheters placed by open surgery using an infra-umbilical midline incision.

Prevalence and risk factors of hepatitis C virus, hepatitis B virus, and human immunodeficiency virus in multiply transfused recipients in Mexico.

Background: Transfusion-transmitted viral infection (TTI) is a major problem in patients receiving blood products. Monitoring high-risk patients is essential for assessing the epidemiology of blood-borne infections.

Study Design And Methods: A 1-year, cross-sectional seroprevalence study in patients with a history of multiple transfusions was conducted.

[Tomography-electroencephalography agreement in pediatric patients with epilepsy].

Objective: to evaluate the tomography-electroencephalography agreement in pediatric patients attended with epilepsy diagnosis at service neuropediatric in the Medical Unit of High Specialization "Adolfo Ruiz Cortines," during the period from January to October of year 2006.

Methods: retrospective, cross-sectional, descriptive, correlational, observational. One hundred eighty files of pediatric patients were reviewed with clinical diagnosis of epilepsy with electroencephalography of date next to their study of tomography; the agreement was realized with the test of kappa, comparing the results of each diagnosis method, in each patient.

[The burnout syndrome in medical residents working long periods].

Objective: to evaluate the burnout syndrome in medical residents with working periods longer than 80 hours per week.

Methodology: an analytical cross-sectional study was conducted with medical residents working at Instituto Mexicano del Seguro Social hospital in Veracruz, México. The residents were classified in two groups.

Pediatric renal transplantation with mycophenolate mofetil immunosuppression in a single center from Mexico.

An MMF-based immunosuppression has reduced the acute rejection rate in adults and in children in the early post-transplantation period. In the present study, pediatric renal transplantation patients on a CyA, MMF, and steroids regimen were prospectively evaluated. Patients with CyA, MMF, and steroid therapy without antibody induction were evaluated for surgical aspects, renal function, rejection, and survival, growth after transplantation, adverse events and medication discontinuation.

Cardiovascular risk stratification by means of the SCORE system in health care workers in Veracruz, Mexico.

Background: To assess cardiovascular disease risk by means of the SCORE system (Systematic Coronary Risk Evaluation) in health care workers (HCW) from Veracruz, Mexico.

Methods: A cross-sectional study was undertaken at the Mexican Institute of Social Security from Veracruz. Seventy six HCW without physical limitations (NYHA Functional Class I) were included.
