1. Erythrocyte lithium—sodium counter-transport was measured in 46 normotensive healthy controls without family history of hypertension, 15 subjects with essential hypertension, but without evidence of family history of high blood pressure, and 43 subjects with essential hypertension and at least one hypertensive first-degree relative. 2. Mean values (mmol h−1 l−1 of erythrocytes) were 0.248 ± 0.092 in controls, 0.258 ± 0.087 in hypertensive subjects without family history (not significant vs controls), 0.360 ± 0.115 in hypertensive subjects with family history of hypertension (P < 0.001 vs controls), 0.334 ± 0.117 in all hypertensive subjects, both with and without family history (P < 0.001 vs controls). 3. Our data confirm the finding of an increased erythrocyte lithium-sodium counter-transport, but with a significant overlap between essential hypertension and control values. Lithium-sodium countertransport is higher only in hypertensive subjects with at least one hypertensive first-degree relative. 4. We suggest that the increase of lithium-sodium countertransport in erythrocytes is not a consistent marker of essential hypertension. It seems to be associated with the family prevalence and/or the hereditability of hypertension, rather than with high blood pressure per se.

Abstract Background: We evaluated the prevalence and the factors associated with repeated high systolic (SBP) and diastolic blood pressure (DBP) at 6- and 11-year follow-ups of children from the Pelotas (Brazil) 2004 Birth Cohort. Methods: All live births to mothers living in the urban area of Pelotas were enrolled in the cohort. Blood pressure (BP) values were transformed into Z-scores by sex, age, and height. High SBP and DBP were defined as repeated systolic and diastolic BP Z-scores on the ≥95 th percentile at the two follow-ups. Prevalence (95% confidence interval) of repeated high SBP, DBP, and both (SDBP) were calculated. Associations with maternal and child characteristics were explored in crude and adjusted logistic regression analyses. Results: A total of 3,182 cohort participants were analyzed. Prevalence of repeated high SBP, DBP and SDBP was 1.7% (1.2-2.1%), 2.3% (1.8-2.9%) and 1.2% (0.9-1.6%), respectively. Repeated high SBP was associated with males, gestational diabetes mellitus (2.92; 1.13-7.58) and obesity at 11 years (2.44; 1.29-4.59); while repeated high DBP was associated with females, family history of hypertension from both sides (3.95; 1.59-9.85) and gestational age <34 weeks (4.08; 1.52-10.96). Repeated high SDBP was not associated with any of the characteristics investigated . Conclusion: Prevalence of repeated high SBP, DBP, and SDBP were within the expected distribution at the population level. Nonetheless, gestational diabetes mellitus, obesity, family history of hypertension, and prematurity increased the risk of repeated high blood pressure measured at two occasions five years apart.

1. The rate (k) of initial efflux of noradrenaline from platelets was determined in 63 individuals. A highly significant correlation was found between diastolic blood pressure and efflux rate. 2. When platelets are incubated in buffers with various Na+ concentrations in the range 110–170 mmol/l a higher Na+ concentration will give a faster efflux of noradrenaline for each concentration tested. 3. The value for k was determined in 41 normotensive first-degree relatives of hypertensive individuals and 21 persons with no family history of hypertension. Efflux rate of noradrenaline was significantly higher in the relatives and within this group was a subgroup with very high k values.

The goal of the present correlational study is to test the hypothesis that anger initiates essential hypertension in Canadian Caucasian adults with a family history of hypertension. The study population will include a cohort of 100 men and women aged 25 to 45 years at enrollment recruited from the University of Ottawa General and Civic Hospitals. Participants who are normotensives will be included in the study given that they have a family history of hypertension. The Spielberger State Trait Anger Expression inventory (STAXI) scales will assess the three main dimensions of anger: State, Trait and Anger Expression. Using a semiautomated blood pressure machine, blood pressure measurements will be conducted by the attending nurse. It is hypothesized that during the three year study, participants with higher STAXI scores will more likely develop hypertension. Results obtained from the present study are expected to highlight the significant contribution of anger as a modifiable behavioral risk factor in the pathogenesis of hypertension.

Introduction: The use of lead-based paint in the manufacturing process on land transportation production contributed to the decline of ambient air quality. The amount of lead level in the painting area exceeded the allowed Threshold Limit Value (TLVs). Excessive lead exposure will provoke the escalation of blood lead levels. Even in a small amount, a lead will cause cardiovascular disorder inside the human's body and raise blood pressure. The research aims to analyze the correlation between environmental factors and individual factors of industrial painters with high blood pressure. Methods: The research used a quantitative method and a cross-sectional design. It involved the whole industrial painters and administration workers at the Internal Control Division. Samples were taken from 20 workers determined using simple random sampling. Independent variables were air lead level, age, healthy family history of hypertension, nutritional status, caffeine consumption, and smoking frequency. Dependent variables were blood lead level and blood pressure. The data obtained from laboratory tests and questionnaires were analyzed using Fisher's Exact Test. Results and Discussion: Correlations were proven to exist between lead level in the work environment and lead level inside the painters’ blood (p = 0.663). Family history of hypertension (p = 0.016) and nutritional status (p = 0.031) were correlated to the Blood Lead Levels (BLLs), whereas BLLs (p = 1.000), age (p = 0.158), caffeine consumption habit (p = 1.000), and smoking frequency (p= 0.663) were not correlated to the blood pressure. Conclusion: The work environment's lead level was correlated with BLLs but did no correlate with blood pressure. Family history of hypertension and nutritional status were the individual factors that correspond with high blood pressure in industrial painters.

Erythrocyte Sodium

1. During 4 weeks 37 normotensive 50-year-old men identified by screening in a random population sample were given 12 g of NaCl daily, in addition to their usual dietary sodium intake. Blood pressure, heart rate, weight, urinary excretion of sodium, potassium and catecholamines, plasma aldosterone and noradrenaline and intra-erythrocyte sodium content were determined on normal and increased salt intake. The subjects were divided into those with a positive family history of hypertension (n = 11) and those without such a history (n = 26). 2. Systolic blood pressure and weight increased significantly irrespective of a positive family history of hypertension. 3. On normal salt intake intra-erythrocyte sodium content was significantly higher in those with a positive family history of hypertension. During high salt intake intra-erythrocyte sodium content decreased significantly in that group and the difference between the hereditary subgroups was no longer significant. 4. In the whole group urinary excretion of noradrenaline, adrenaline and dopamine increased whereas plasma aldosterone decreased during the increased salt intake. 5. Thus, in contrast to some earlier studies performed in young subjects, our results indicate that moderately increased sodium intake acts as a pressor agent in normotensive middle-aged men whether there was a positive family history of hypertension or not. We confirm that men with positive family history of hypertension have an increased intra-erythrocyte sodium content, and that an increase in salt intake seems to increase overall sympathetic activity.
