Avaliação da pressão arterial sistêmica em cães obesos: comparação entre os métodos oscilométrico e doppler ultrassônico

Obesity is the most common nutritional problem in dogs and it can cause various harmful effects on animal health. However, the effect of this condition on systolic blood pressure (SBP) in obese dogs is controversial. The indirect method of measuring PAS is the most commonly used in veterinary medicine for the diagnosis of systemic hypertension, because it is more practical and easy to access. There is little scientific information about the comparison of the two non- invasive methods of measurement of blood pressure in obese dogs. Therefore, the objective of this study was to evaluate the SBP in obese dogs by comparing both indirect methods of measuring blood pressure, with oscillometric and doppler vascular in order to verify the differences in blood pressure values, but also the best method to assess the SBP dogs in this body score condition. The study complain blood pressure measurement of 50 dogs, with were divided in obese dogs with mean body condition score (BCS) of 8.42 +/- 0.50 (n = 25) and dogs with ideal BCS of 4.56 +/- 0.51 (n = 25). At comparison of blood pressure values, SBP values obtained by doppler method (152 +/- 16mmHg) were higher than the oscillometric (136 +/- 11mmHg). Correspondence analysis determined by multivariate statistical analysis showed correlation between body condition and the procedure of the SBP. These findings suggest that the indirect method doppler can better reflect the SBP in obese dogs.

Topography of the blood vessels in the hilum of the kidney of Myrmecophaga tridactyla

The study was undertaken in 10 formol-imbibed kidneys of great anteater (Myrmecophaga tridactyla). After the dissection the following characteristics were showed: kidney blood vessels are distributed in 2 different sites, namely hilar and extrahilar, amounting 3 to 6 in the right side 3 to 7 in the left side. Arterial branches in extrahilar region range from 1 to 2 in both sides and in hilar region they present from 1 to 4 in the right and 1 to 2 in the left. Venous roots occur in 1 to 2 vessels in the right and 1 to 3 vessels in the left, occupying only the hilar region, except one case where it was present in the right side.

Prevalência de hipertensão arterial em adolescentes escolares em Ibitinga: importância do histórico familiar

Hypertension (H) affects approximately 1,2 billion of people in the world. Among the main risk factors are weight excess, sedentary lifestyle, socio economic condition and family history of H. The main aim of this study was to assess the prevalence of hypertension in teenager scholars in Ibitinga, finding the role of family history of H and to correlates these results with nutritional condition, anthropometric variables and socio economic condition. This research analyzed 150 participants (50 teenager students and their parents) in public and private schools. All the volunteers had their weight (kg) and height (m) measured to calculate the body mass index (BMI). The students were classifieds from table of percentile of obesity (Centers for Disease Control and Prevention, CDC). The blood pressure (BP) was evaluated according to V Arterial Hypertension Brazilian Guidelines (VAHBG, 2006). The high values considered of BP were: ≥140x90 mmHg for adults and percentile >95 for teenagers. The socio economic condition was categorized from IBGE. Among the students, 36% had high BP and 20% borderline. The percentage of high BP were bigger in the public (44%) than private schools (28%), showing a negative correlation between socio economic condition and systolic BP (SBP, r=0.2857) and diastolic BP (DBP, r=0,0165). The prevalence of elevated BP was higher in the girls of public schools (47% vs 40% boys) and in the boys at the private schools (33% v s23%). Weight excess was present in 42% of children (12% obesity and 30% overweight). Again, public schools had prevalence of obesity (52% vs 3% in the private) which was not correlated with socio economic condition. Percentage of overweight and obesity were bigger in the girls of both public (54% vs 50% boys) and private (38% vs 25%) schools. Among the students with H, 67% were overweight. Elevated BP was found in 54% of the fathers and 32% of the mothers. With respect to nutritional condition, 56% of the...

Non-invasive brain stimulation for the management of arterial hypertension

The neural control of the cardiovascular system is a complex process that involves many structures at different levels of nervous system. Several cortical areas are involved in the control of systemic blood pressure, such as the sensorimotor cortex, the medial prefrontal cortex and the insular cortex. Non-invasive brain stimulation techniques - repetitive transcranial magnetic stimulation (rTMS) and transcranial direct current stimulation (tDCS) - induce sustained and prolonged functional changes of the human cerebral cortex. rTMS and tDCS has led to positive results in the treatment of some neurological and psychiatric disorders. Because experiments in animals show that cortical modulation can be an effective method to regulate the cardiovascular system, non-invasive brain stimulation might be a novel tool in the therapeutics of human arterial hypertension. We here review the experimental evidence that non-invasive brain stimulation can influence the autonomic nervous system and discuss the hypothesis that focal modulation of cortical excitability by rTMS or tDCS can influence sympathetic outflow and, eventually, blood pressure, thus providing a novel therapeutic tool for human arterial hypertension.

Prevalence of Arterial Hypertension Among Seventh-Day Adventists of the Sao Paulo State Capital and Inner Area

Background: Inadequate life habits are known to favor hypertension, and Adventists recommend healthy life habits. Objective: To assess the prevalence of hypertension among Seventh-Day Adventists from the inner Sao Paulo state and Sao Paulo state capital. Methods: This study assessed 264 Adventists (mean age, 41.17 +/- 15.27 years; women, 59.8%) with a high religiosity level assessed by use of the Duke University Religion Index. Blood pressure was measured with a validated automatic device. The significance level adopted was p < 0.05. Results: The total prevalence of hypertension was 22.7% (27.4% in the inner state and 15% in the capital). The Adventists from the capital differed from those of inner state as follows (p < 0.05), respectively: higher education (62% vs 36.6%); employed by a third party (44%) vs self-employed (40.9%); family income (8.39 +/- 6.20 vs 4.59 +/- 4.75 minimum wages); individual income (4.54 +/- 5.34 vs 6.35 +/- 48; couple responsible for family income (35% vs 39.6%); vegetarianism (11% vs 3%); blood pressure (115.38 +/- 16.52/68.74 +/- 8.94 vs 123.66 +/- 19.62/74.88 +/- 11.85 mmHg); white ethnicity (65% vs 81.1%); married (53% vs 68.9%); lower tangible support in the social aspect (15.7 +/- 5.41 vs 16.9 +/- 4.32); and recalling the last time one's blood pressure was measured (65% vs 48.8%). On multivariate analysis, hypertension associated with the following: 1) vegetarianism (OR 0.051; 95% CI: 0.004-0.681); 2) educational level (OR 5.317; 95% CI: 1.674-16.893); 3) recalling the last time one's blood pressure was measured (OR 2.725; 95% CI: 1.275-5.821); 4) being retired (OR 8.846; 95% CI: 1.406-55.668); and 5) being responsible for family income (OR 0.422; 95% CI: 0.189-0.942). Conclusion: The prevalence of hypertension among Adventists was lower as compared with that reported in Brazilian studies, and it was lower in the Sao Paulo state capital as compared with that in the inner Sao Paulo state, possibly because of the better socioeconomic conditions and life habits of the former.
