Item Acesso aberto (Open Access) Associação do índice de massa corporal com a glicemia de jejum e pressão arterial em indígenas(Universidade Federal do Pará, 2008-02-13) REIS, Rosilene Costa; GUERREIRO, João Farias; http://lattes.cnpq.br/1000688763895346This study aims to measure and describe the shape of the relationship between BMI, fasting plasma glucose and blood pressure on indigenous groups of Amazonia Para. We studied 297 adults across the ethnic Kaip (Xikrin and Kararaô), Araweté, Parakanã, and Arara Asurini located in the State of Pará, northern Brazil. The variables BMI, blood glucose and blood pressure were measured and categorized as still in overweight, obesity, diabetes, the glucose intolerance and hypertension. The relationship of BMI with the other variables was tested by linear regression method by adopting a significance level of 5% (p ≤ 0.05). Mean BMI (23.7 kg/m2), fasting plasma glucose (83.4 mg / dL), diastolic blood pressure (60.0 mmHg) and age (49 years) showed no significant difference between genders and for men only systolic blood pressure (98.0 mmHg) was higher. The prevalence of overweight was 23.6% and obesity from 5.7%. Were not identified new cases of diabetes mellitus type 2, but four cases (1.3%) of the disease were reported. The impaired glucose tolerance was present in 2.4% of the population and hypertension in 1.3%. The BMI associated with the glucose, systolic blood pressure and diastolic blood pressure (DBP), is better explained from diastolic blood pressure (BMI = 20590 +0.52 DBP). The relationship of BMI with blood glucose levels and blood pressure was positive, but further studies are needed to have more clarity between cause and effect.Item Acesso aberto (Open Access) Efeito da suplementação de altas doses de colecalciferol sobre o comportamento da pressão arterial em pacientes normotensos com diabetes mellitus tipo 1(Universidade Federal do Pará, 2018-12-26) QUEIROZ, Natércia Neves Marques de; FELÍCIO, João Soares; http://lattes.cnpq.br/8482132737976863Type 1 diabetes mellitus is an endocrine disease highly associated to cardiovascular (CV) risk. Vitamin D (VD) deficiency has been associated to a burden of chronic diseases due to the presence of vitamin D receptors (VDR) through diverse human tissues such as smooth vascular muscle, endothelium, cardiomiocytes and juxtaglomerular cells. Some studies have suggested an inverse relationship between vitamin D levels and blood pressure. High mean blood pressure levels have been found in vitamin D deficient patients. Additionally, previous studies have suggested that the VD-VDR complex might act as a negative regulator factor over renin angiotensin system, which could be responsible for positive effects on blood pressure. The main objective of this study was to evaluate high doses vitamin D supplementation effects on blood pressure of normotensive T1DM patients. Our study was a prospective interventionist study in 35 T1DM patients. The patients with vitamin D lower them 30ng/ml received 10.000UI/daily e if was 30-60 ng/ml was gave 4.000UI/daily. They made 24-hour ambulatory blood pressure monitoring, gycated hemoglobin, creatin, lipids profile, PCRus, before and after 12 weeks. We found an expressing reduce of systolic and diastolic morning blood pressures (117 ± 14 vs 112±14, p<0,05; 74±9 vs 70±10 mmHg, p<0,05, respectively) with no changes in order pressoric markers. Besides, we notice correlation between levels of VD after supplementation and diastolic morning blood pressure (r= -0,4; p<0.05). In conclusion, our study suggest that was an association with supplementation of high doses of vitamin D and reduce of morning blood pressure in normotensives type 1 diabetes mellitus patients.Item Acesso aberto (Open Access) Prevalência de hipertensão arterial em pacientes com oclusão do ramo da veia central da retina(2008-04) ROSA, Alexandre Antonio Marques; ORTEGA, Kátia Coelho; MION JÚNIOR, Décio; NAKASHIMA, YoshitakaPURPOSE: To identify in patients with branch retinal vein occlusion using ambulatory blood pressure monitoring and clinical blood pressure measures: hypertension prevalence, and nocturnal profile of blood pressure. METHODS: Prospectively, 93 eyes of 83 patients with branch retinal vein occlusion were submitted to ophthalmological examination. Afterwards the patients were submitted to clinical evaluation and blood pressure monitoring. Non-dipper was defined as a fall in systolic blood pressure < 10%, and dipper when this value was higher. RESULTS: Disease affected one eye in 73 (88%) patients. The temporal superior branch was the site of occlusion in 61 (65.6%) eyes, while in the others the infero-temporal branch was affected. Seventy six (92%) patients were diagnosed as hypertensive after clinical evaluation. Ambulatory blood pressure monitoring identified 76 hipertensives, 5 normotensives, 1 white-coat hypertensive and one masked hypertensive subjects. The two latter were excluded from the analysis. Of the 81 analyzed patients, forty (49%) were dippers and 41 (51%) were non-dippers. Among the HT (n=76), 36 (47%) were dippers and 40 (53%) were non-dippers. CONCLUSION: Prevalence of hypertension in our series was extremely high (92%) which suggests that physiopathology of the disease has a close relationship with changes promoted by hypertension. A little more than half of the hypertensives were non-dippers (n=40; 52,6%). These evidences suggest that a 24-hour sustained level of blood pressure may be an additional risk factor for branch retinal vein occlusion.
