Evaluation of dietary intake of calcium in adult subjects with idiopathic arterial hypertension

The calcium-intake relationship with other alimentary and anthropometric variables was investigates in a group of 60 adult (19-75 year-old) subjects, 50 females and 10 males, with essential arterial hypertension (DAP > 90 mmHg). The calcium intake was assessed by three different protocols: 24-hour food intake recall, food-frequency questionnaire and 3 day self-food intake register, repeated along with anthropometric measurements on three different occasions (2-15 month-intervals). The calcium intake assessed by the three methods, as well as the anthropometric data, were statistically similar on all three occasions. The mean data were then compared with those form the control, composed of 75 healthy subjects matched with the hypertensive group by age and sex. The patients ingested less calcium (mean +/- SD) than the controls on the daily (517 +/- 271 x 740 +/- 353 mg/d) and body-weight (8.1 +/- 5.0 x 11.4 +/- 5.9 mg/kg/d) basis. Among the males the calcium intake was the only difference found between groups and could be attributed to the lower intake of calcium-rich foods. The hypertensive females showed also higher lean-body mass (Body-mass index and arm muscle circumference). Thus the calcium intake discriminated both groups being associated with changes in other nutritional parameters only in females.

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...

Role of α1-, and α2- and β-adrenoceptors of the median preoptic area on the water intake, renal excretion, and arterial pressure induced by ANG II

The present experiments were conducted to investigate the role of the α1-, α2- and β-adrenergic receptors of the median preoptic area (MnPO) on the water intake and urinary electrolyte excretion, elicited by central injections of angiotensin II (ANG II). Prazosin (an α1-adrenergic receptor antagonist) and yohimbine (an α2-adrenergic receptor antagonist) antagonized the water ingestion, Na +, K +, and urine excretion induced by ANG II. Administration of propranolol, a β-adrenergic receptor antagonist increased the Na +, K +, and urine excretion induced by ANG II. Previous treatment with prazosin and yohimbine reduced the pressor responses to ANG II. These results suggest that the adrenergic neurotransmission in the MnPO may actively participate in ANG II-induced dipsogenesis, natriuresis, kaliuresis, diuresis and pressor responses in a process that involves α1-, α2-, and β-adrenoceptors.

Repercussões cardiovasculares em crianças com distúrbios respiratórios obstrutivos do sono: revisão de literatura

Objective: To review the cardiovascular consequences of obstructive sleep-disordered breathing in children Data source: Medline and Ovid data base. Study selection: pediatric articles (original articles and case report) that investigated the obstructive sleep-disordered breathing in children Data synthesis: The obstructive sleep-disordered breathing can lead to serious cardiovascular consequences such as pulmonary hypertension, pulmonary edema and anatomic and functional abnormalities Conclusions: The knowledge of cardiovascular repercussions allows in better management of pediatric patients and may result in positive consequences for treatment and follow up of these patients.

Anatomical description of arterial segment of spleen of deer

The anatomosurgical segmentation of the arteries of the spleen was studied in 31 deer of the species Mazama gouazoubira and Blastocerus dichotomus by means of vascular injection with latex and vinyl acetate and radiographic examination. The arteria lienalis penetrated through the hilus lienis in 87% of the cases, whereas an extrahilar artery was present in the other cases. An extraparenchymal division of the lineal artery into two, three or four segmental arteries was observed in 74% of the cases. Anastomoses between intraparenchymal arterial branches were rare and of a reduced calibre.

O papel de enfermeiros na equipe multidisciplinar frente ao sobrepeso/obesidade em ambiente de trabalho

Overweight and obesity are pandemics and have been widely discussed in Public Health and Health at Work. Comorbidities such as metabolic syndrome, hypertension, diabetes mellitus type 2, orthopedic disorders and coronary diseases can induce to absenteeism, reduced work performance, disability and death. The aim of this review is to discuss the role of the nurse in control and prevention of these illnesses in the workplace. We concluded that occupational health nurses work should act proactively with a multidisciplinary team aimed at individual and collective monitoring of actions designed to control and prevent overweight and obesity. Furthermore, this professional should follow up the health of individual workers with a high body mass index in order to warn and prevent comorbidities related to these conditions.

Boas práticas de laboratório e biossegurança: prevenção dos riscos ergonômicos

El control de los riesgos ergonómicos es parte del paquete de medidas de Buenas Prácticas de Laboratorio y Bioseguridad. De este modo, la mala postura, la iluminación o ventilación inadecuadas , prolongada jornada de trabajo, la monotonía y la actividad repetitiva, intensa rutina, el control de la productividad , el estrés y el trabajo por la noche son factores a los riesgos ergonómicos. Como se relacionan a los elementos físicos y de organización también pueden interferir con la comodidad y la salud del personal de laboratorio. Riesgos ergonómicos no sólo pueden generar trastornos psicológicos y fisiológicos que causan graves daños a la salud, sino también comprometer la productividad del laboratorio y reducir el equipo de seguridad , ya que producen cambios en el cuerpo y el estado emocional, tales como trastornos o lesiones relacionadas con el cansancio físico producido por el trabajo repetitivo, dolor muscular, alteraciones del sueño, diabetes, trastornos de los nervios , la taquicardia , las enfermedades del aparato digestivo (gastritis y úlcera ), tensión, ansiedad, problemas de espalda y la hipertensión. En este trabajo se propone una secuencia de actividad laboral (gimnasia) en el intervalo de tiempo pequeño, respetando las instalaciones y el espacio físico disponible en el ambiente del trabajo, como una estrategia para mejorar la calidad de vida laboral, para aumentar la productividad, mejorar la disposición a trabajar y para aumentar el conocimiento del cuerpo y de la interacción social.
