Herdabilidade de preditores do risco cardiovascular

genetic and environmental factors contribute to the development of cardiovascular risk and that influence can be differentiated by factors characteristic of each population, age and sex. Aim: To investigate the heritability of anthropometric and biochemical markers as predictors of cardiovascular risk in men and women of different age groups, using the method of twins. Methods: A sample of 88 subjects and of these 52 children and adolescents (08-17 years old) 32 monozygotic (20 female and 12 male) and 20 dizygotic (12 female and 08 male) and 36 adults (18-28 years age) 24 monozygotic (08 female and 16 male) and 12 dizygotic (06 female and 06 male), living in the metropolitan region of Natal / RN, Brazil. Anthropometric measures were taken as the height, body mass, waist circumference (WC), sum of skinfolds (ΣDC), fat percentage CUN-BAE, BMI and conicity. Biochemical markers analyzed were: fasting glucose (GLU), total cholesterol (COL), HDL-C, LDL-C and triglycerides (TG). After processing the data the index of heritability (h2) = (S ² MZ) / S ² DZ (DZ S ²) X100 was applied disaggregated by sex and age. Results: The variables showed differential heritability of behavior for men and women, depending on age. The variables with the highest heritability values were ΣDC, GLU, HDL, TG, in men and BMI, WC, ΣDC, GLU, HDL-C and TG in women. And more influenced by the environment variables were: body mass, BMI, Chol, LDL-C in men; body mass and LDL-C in women. Conclusion: Differences index of heritability by gender for cardiovascular risk predictors may assist in planning specific intervention strategies according to gender and stage of life of that individual. It is from the level of environmental influence that can run interventions for changes of components related to cardiovascular risk

Relação entre a doença periodontal e doença cardiovascular: há uma preocupação por parte dos que fazem clínica médica e odontológica na cidade de Natal?

The relationship between periodontal and cardiovascular diseases is a reality in the current days. The knowledge about the role of periodontal disease as a risk factor to cardiovascular disease from dentistry and physicians is very important to try to eliminate this risk factor. The aim of this work was to investigate, using a questionary, if physicians and dentistry are aware about this relationship and if they think that it is important. These forms were distributed in 4 groups: cardiologists (n=90), physicians from other specialist (POS) (n=110), periodontists (n=35) and dentistry from other specialist (DOE) (n=85). We had a loss off 32,4% of the total sample due to a lack of response of some professionals. Our results showed that all cardiologists, all dentists and 68,2% of POE said that they had gotten information about the relationship between periodontal and cardiovascular disease, and just 6 POS don t believe that this relationship can occur. When questioned if, even when a periodontal disease is diagnosed, there is a habit to treat or orient the patient for treatment, 29,5% of cardiologists answered no, 25,5% of POE also answered that they did not orient and only 1 DOE answered that he did not treat nor orient. All periodontists said that treat their patients when periodontal disease was identify. The physicians seem not to find important the relationship that exist between periodontal and cardiovascular diseases and the dentistry have shown a good knowledge about this subject. Maybe, if physicians and dentistry work together, the incidence of cardiovascular disease decreases

Proposta de Intervenção para Auxiliar a Reabilitação Motora e Cognitiva de Pacientes com Acidente Vascular Cerebral

Stroke is the leading cause of combined motor and cognitive disability worldwide. The rehabilitation of stroke patients is mostly directed towards motor recovery through the training of the affected member under supervision of a Physical Therapist. In the present study we introduce a new approach for both cognitive and motor therapy, which relies on motor imagery of the upper limbs and working memory training. This therapy should be utilized as an adjuvant to physical therapy. Ten individuals (5 men and 5 women) were selected for the pilot study, all of them in the acute phase of the first ischemic stroke episode. The control group had 5 individuals who were submitted to physical therapy only, whilst the other 5 patients in the experimental group also performed the cognitive and motor training with a video game specially built for this study. Two patients left the experimental group before the end. Total training lasted for 9 weeks, 2 times a week, for half an hour. Patients reported they enjoyed playing the game, even though it required a lot of mental effort, according to them. Plus, they considered it had a beneficial influence in their activities of daily living. No side effects were reported. Preliminary results suggest there is a difference between groups in cognitive and upper limb motor evaluation following the intervention. It is important to notice that our conclusions are limited due the small sample number. Overall, this work is supported by other studies in literature focused in rehabilitation with motor imagery and working memory and indicate a continuity of the research, increasing total training hours
