Abstract. Introduction: the Belgian province of Luxembourg has a high incidence of cardiovascular (CV) disease according to the MONICA register. Surveys conducted in adults and children have also found high CV risk factor levels in this province. Design: cross-sectional study. Objective of the present study: to collect data about blood pressure (BP) and its determinants in adolescents from this high CV risk population and to analyse their relationship. Participants: 1526 adolescents (12-17 years) in 24 secondary schools of the province. Results: mean systolic BP levels were 125 mmHg (sd= 12 mmHg) and 122 mmHg (sd= 11 mmHg) for boys an girls, respectively. Mean diastolic BP was equal to 74 mmHg (sd = 10 mmHg) in both genders. Systolic BP increased with age and differed significantly between genders from 15 years onwards. Body fatness indices increased with age except waist-to-hip ratio in girls and triceps skinfold in boys. Regression models including age, anthropometric indices and physical activity explained a small percentage of BP variance (for systolic BP, r²= 0.21 and 0.12 for boys and girls, respectively). Weight was the first parameter related to BP in correlation with regression analyses. Conclusions: this study showed high BP and body fatness indices in adolescents fom a high CV risk population. The model under study showed a moderate relationship between body fatness and BP. This finding suggests other influences as genetic component to account for the high levels observed. [less ▲]

In a population study conducted from 1985 to 1989 in Belgium, the authors investigated whether exposure to cadmium is associated with blood pressure elevation and with an increased prevalence of cardiovascular diseases. The participants, aged 20-88 years, constituted a random sample of the households living in two low exposure areas (n = 803) and two high exposure areas (n = 1,283). For each exposure level, a rural and an urban district were selected. The cadmium levels in blood (8.5 vs. 11.0 nmol/liter) and urine (7.2 vs. 8.7 nmol/24 hours) were significantly (p less than 0.001) raised in the two high exposure areas compared with the two low exposure areas (p less than 0.001). Systolic pressure was similar in both rural areas, but in the urban area with high exposure systolic pressure was 5 mmHg (p less than 0.001) higher than in the control town. Diastolic pressure was similar in the four districts and the same was true for the prevalence of hypertension and of other cardiovascular diseases. Adjustment of systolic pressure for blood and urinary cadmium did not remove the difference in systolic pressure between both urban areas, suggesting that it was not related to the cadmium burden on the environment. Further analyses in individual subjects showed that neither blood pressure nor the presence of cardiovascular diseases were significantly and positively correlated with blood and urinary cadmium. Thus, the present population study did not confirm the hypothesis that increased exposure of the population to cadmium is associated with blood pressure elevation and with a higher prevalence of cardiovascular diseases.

The profound endocrine upheaval of pregnancy is frequently associated with changes in the function and structure of the blood and lymph microvasculature of the skin and mucosae. Palmar erythema is frequent but rarely severe and is associated with burning sensations. Spider telangiectasias develop in the majority of pregnant White women but are less often identified in women with darker skin. Hemangiomas and glomus tumors occur in one-third of women. A firm edema may develop on the face and extremities in the final months of pregnancy. Venous hypertension and varicosities of the lower limbs are common. Gingivitis, gum hypertrophy, and pyogenic granuloma are common in the oral cavity. The vaginal mucosa is also affected, showing a violaceous aspect, at times accompanied by varicosities of the vulva. Many gestational vascular changes regress spontaneously in the postpartum phase. Some vascular tumors may need to be treated with a vascular laser or intense pulsed light. [less ▲]

Blood-oxygen binding in healthy Standardbred horses

The purpose of this study was to determine the effect of regulating factors on the oxygen equilibrium curve (OEC) under standard conditions and then to calculate the oxygen extraction between arterial and jugular venous blood in healthy Standardbred horses. The results were compared to those previously obtained in humans and cattle, using the same experimental method. The partial oxygen pressure at 50% saturation of haemoglobin, measured under standard conditions (standard P50), was 24.8 +/- 2.0 (SD of mean) mm Hg. This value was similar to the cattle standard P50 (25.0 +/- 1.4 mm Hg, SD of mean) but lower than the human standard P50 (26.6 +/- 1.2 mmHg, SD of mean) previously reported using the same experimental method. The effects of regulating factors on the standard OEC were also determined, and a major effect of pH and temperature was noted. In contrast, partial carbon dioxide pressure played only a minor role in horses, compared to cattle and humans. No significant correlation was found between phosphate and chloride concentrations and standard P50. (c) 2004 Elsevier Ltd. All rights reserved. [less ▲]

A long-term time series of plankton records collected by the continuous plankton recorder (CPR) Survey in the northeast Atlantic indicates an increased occurrence of Cnidaria since 2002. In the years 2007 and 2008, outbreaks of the warm-temperate scyphomedusa, Pelagia noctiluca, appeared in CPR samples between 45°N to 58°N and 1°W to 26°W. Knowing the biology of this species and its occurrence in the adjacent Mediterranean Sea, we suggest that P. noctiluca may be exploiting recent hydroclimatic changes in the northeast Atlantic to increase its extent and intensity of outbreaks. In pelagic ecosystems, Cnidaria can affect fish recruitment negatively. Since P. noctiluca is a highly venomous species, outbreaks can also be detrimental to aquaculture and make bathing waters unusable, thus having profound ecological and socio-economic consequences.
