A Comparison of the Academic Achievement at the End of the Medicine Undergraduate Degree Program Between Students Who Only Used the University Admission Test and Those Who Used the University Admission Test Plus Marks from the High School National Exam (ENEM) at a Single Brazilian Center.

Purpose: The role of marks in the University Admission Test (UAT) plus the marks from pre-university academic records in predicting academic achievement at the end of the Medicine undergraduate degree program is not completely known. This study was undertaken to compare the performance of marks in the UAT alone with those of the UAT plus marks from the National High School Exam (ENEM in Brazil) regarding students' outcomes at the end of the Medicine undergraduate degree program.

Methods: Fifty-one (51) students from the last semester (12th) of our Medicine undergraduate degree program were included in the study.

University Admission Test Associates with Academic Performance at the End of Medical Course in a PBL Medical Hybrid Curriculum.

Purpose: Most studies assessing the value of the university admissions test (UAT) to predict academic performance at the end of a medical course were carried out on lecture-based medical courses. However, the association between performance in the UAT with academic achievement at the end of medical course in a problem-based learning (PBL) medical hybrid curriculum remains controversial. The aim of this study was to correlate marks in the UAT with those obtained in the Organized Structured Clinical Examination (OSCE), in the progress testing (PT), and in the final marks of the clerkship (FMC).

Abnormalities in electrocardiographic ventricular repolarization in patients with dengue virus infection.

Introduction: Dengue virus infection (DENV) is an arboviral disease that affects millions of people in many countries throughout the world every year. The disease is caused by the bite of a mosquito (Aedes aegypti and / or Aedes albopictus). The symptoms/signs observed in this arboviral disease are unspecific, and the blood count usually shows leukopenia and thrombocytopenia.

What is the meaning of homocysteine in patients on dialysis?

Objective: To evaluate the determinants of total plasma homocysteine levels and their relations with nutritional parameters, inflammatory status, and traditional risk factors for cardiovascular disease in renal failure patients on dialysis treatment.

Design: The study was conducted on 70 clinically stable patients, 50 of them on hemodialysis (70% men; 55.3 ± 14.

Influence of chronic renal failure on stereoselective metoprolol metabolism in hypertensive patients.

The influence of chronic renal failure on the stereoselective metabolism of rac-metoprolol was investigated in 15 hypertensive patients, 7 of them with chronic renal failure and 8 with normal renal function. They were treated with rac-metoprolol (200 mg) for 7 days. The patients of both groups presented stereoselectivity in metoprolol metabolism, favoring the formation of 1'R-alpha-hydroxymetoprolol (AUC(1(')R/1(')S)(0-24) approximately 2.

[Relationship between regular attendance to ambulatory appointments and blood pressure control among hypertensive patients].

Objective: Our objective was to determine the rate of hypertensive patients with controlled BP (BP < 140 x 90 mmHg) and to study its relationship with regular attendance to ambulatory appointments.

Methods: A total of 245 medical records from patients followed up at the Unidade Clínica de Hipertensão Arterial (Clinical Unit of Arterial Hypertension) HCFMRP-USP for a period of one year were randomly and retrospectively reviewed. The patients were classified as assiduous (A) and as regularly absent to scheduled appointments (F), with the second group being defined as those who failed to appear longer than 30 days after the scheduled appointment.

Dynamic and kinetic disposition of nisoldipine enantiomers in hypertensive patients presenting with type-2 diabetes mellitus.

Objective: Nisoldipine (N) is a dihydropyridine calcium antagonist marketed as a racemic mixture and used for the treatment of hypertension. In the present study, we investigated the influence of type-2 diabetes mellitus (DM) on the enantioselective pharmacokinetic and dynamic parameters of N.

Methods: Seventeen hypertensive patients, nine of them with DM, were investigated in a cross-over study with administration of rac-N as coat-core tablets (20 mg day(-1)) or placebo for 15 days each.
