Influence of educational level on myocardial hypertrophy of hemodialysis patients

Introduction: Chronic renal disease is associated with a high cardiovascular risk. Data from the general population associate cardiovascular diseases with low educational level, but no study has evaluated this association in patients on hemodialysis. Objective: This study aimed at evaluating the association between educational level, hypertension, and left ventricular hypertrophy in patients on chronic hemodialysis. Methods: A standard socioeconomic questionnaire was applied to 79 hemodialysis patients at the Hospital das Clínicas of Faculdade de Medicina de Botucatu, state of São Paulo. Clinical, laboratory and echocardiographic data were obtained from medical records. The patients were divided into two groups according to the median educational level, as follows: G1, patients with three or less years of schooling; G2, patients with more than three years of schooling. Results: Blood pressure, interdialytic weight gain, and variables statistically different in the two groups (p < 0.2) underwent multiple analysis. Independent associations were stated with p < 0.05 in multiple analysis. The mean age of patients was 57 ± 12.8 years, 46 were males (57%), and 53 white (67%). The variables selected for multiple analysis were: age (p = 0.004); educational level (p < 0.0001); body mass index (p = 0.124); left ventricular diameter (p = 0.048); and left ventricular mass index (p = 0.006). Antihypertensive drugs were similar in both groups. Systolic blood pressure (p = 0.006) and years of schooling (p = 0.047) had a significant and independent correlation with left ventricular mass index. Conclusion: In hemodialysis patients, left ventricular mass associated not only with blood pressure but also with educational level.

Tele-education on Leprosy: Evaluation of an Educational Strategy

The purpose of this research was to evaluate educational strategies applied to a tele-education leprosy course. The curriculum was for members of the Brazilian Family Health Team and was made available through the São Paulo Telehealth Portal. The course educational strategy was based on a constructivist learning model where interactivity was emphasized. Authors assessed motivational aspects of the course using the WebMAC Professional tool. Forty-eight healthcare professionals answered the evaluation questionnaire. Adequate internal consistency was achieved (Cronbach's alpha = 0.79). More than 95% of queried items received good evaluations. Multidimensional analysis according to motivational groups of questions (STIMULATING, MEANINGFUL, ORGANIZED, EASY-TO-USE) showed high agreement. According to WebMAC's criteria, it was considered an awesome course. The tele-educational strategies implemented for leprosy disclosed high motivational scores.

Aortic aneurysm surgery: problems and innovations

Um longo caminho foi percorrido desde as primeiras intervenções cirúrgicas feitas para o tratamento do aneurisma de aorta abdominal. Ao longo deste tempo, várias inovações foram criadas, no sentido de reduzir a invasividade dos procedimentos e melhorar sua segurança e durabilidade. Nesta revisão, são discutidos os principais e recentes avanços em intervenções sobre aneurismas aórticos, incluindo a restauração aórtica endovascular, a cirurgia aórtica videolaparoscópica, as técnicas híbridas convencionais e endovasculares, as técnicas combinadas videolaparoscópicas e endovasculares, bem como as perspectivas futuras, tanto para aorta torácica como abdominal. Diante de tantas transformações e evolução, o cirurgião vascular moderno terá que ter sua mente aberta para as novidades e desenvolver capacitação ampla com diferentes técnicas para proporcionar a melhor opção terapêutica para seus pacientes.

The Brazilian pediatric myelodysplastic cooperative group strategies: are they relevant to improve educational approach and correct diagnosis?

Brazil is a wide country with huge contrasts. Its peculiarities can highlight environmental factors that could influence the frequencies of different cancers. The standard treatment and results achieved from several different areas of the country may not be found in others. The establishment of a national cooperative group has the potential to improve outcomes. The The Brazilian Cooperative Group on Pediatric Patients with Myelodysplastic Syndrome (BCG-MDS-PED) was first organized in January 1997 as a working group of hematologists, pediatric oncologists, pediatric-hematologists, molecular biologists and other professionals in order to study pediatric (age < 18 years) MDS. Six distinct subcommittees constituted with members from several universities: cytology, histopathology, clinical, cytogenetics, molecular biology and epidemiology. The goals of the BCG-MDS-PED were: (i) to offer support for diagnosis and orientation for treatment; (ii) educational Support for the colleagues all over the country and (iii) research on pathogenesis and new approaches for pediatric MDS patients. There are socio-economical differences among the five regions of the country. The BCG-MDS-PED believes that it is absolutely necessary to Study the clinical, cellular, molecular and epidemiological aspects of MDS, taking in account these peculiar differences among populations and regions. Since 1997, 114 pediatric cases were referred to the BCG-MDS-PED from 21 centres. Seven Brazilian states have sent cases to the group, 31 patients were referred from universities, 73 patients from pediatric oncology units (foundations) and 10 patients came from private clinics. Some of these patients have been followed up and/or treated by the physician who referred them to the BCG-MDS-PED for confirmation of the initial diagnosis. The majority of these physicians have required orientation on diagnostic and treatment issues, as well as to complete cytogenetic and molecular studies. From these 114 patients, 64 patients were confirmed as MDS. We believe that, the more numerous the MDS-studied cases, the more experienced will be the referee group on clinical and laboratory features on childhood MDS in Brazil.

Psychophysical power functions for estimates of area: Effects of age and educational levels

The purpose of the present study was to verify the memory exponents of power function for area in observers of different age and educational levels (elementary school, high school or undergraduate school), using the psychophysics method of magnitude estimation. For the age level I (17 to 30 years old) there was no difference among educational levels, although for the age level II (45 to 60 years old) the differences were significant. Tn the age level II, there was a tendency for greater variability of the responses for lower educational levels. The data obtained for the age level I did not show the same results, although a significant difference among the three educational levels was observed. We call conclude that the mnemonic processes present different results when we observe the answers from observers with different ages. This result leads us to suppose that the motivational factor related to the stimulus used can interact with the mnemonic processes.

The effectiveness of educational practice in diabetic foot: a view from Brazil

Background: The aim of the present study was to evaluate the prevention and self-inspection behavior of diabetic subjects with foot at ulcer risk, no previous episode, who participated in the routine visits and standardized education provided by the service and who received prescribed footwear. This evaluation was carried out using a questionnaire scoring from 0-10 (high scores reflect worse practice compliance).Results: 60 patients were studied (30 of each sex); mean age was 62 years, mean duration of the disease was 17 years. As for compliance, 90% showed a total score <= 5, only 8.7% regularly wore the footwear supplied; self foot inspection 65%, 28,3% with additional familiar inspection; creaming 77%; proper washing and drying 88%; proper cutting of toe nails 83%; no cuticle cutting 83%; routine shoe inspection 77%; no use of pumice stones or similar abrasive 70%; no barefoot walking 95%.Conclusion: the planned and multidisciplinary educational approach enabled high compliance of the ulcer prevention care needed in diabetic patients at risk for complications. In contrast, compliance observed for the use of footwear provided was extremely low, demonstrating that the issue of its acceptability should be further and carefully addressed. In countries of such vast dimensions as Brazil multidisciplinary educational approaches can and should be performed by the services providing care for patients with foot at risk for complications according to the reality of local scenarios. Furthermore, every educational program should assess the learning, results obtained and efficacy in the target population by use of an adequate evaluation system.
