High blood pressure and the incidence of non-insulin dependent diabetes mellitus: Findings in A 11.5 year follow-up study in the Netherlands

To examine the contribution of cardiovascular risk factors to the development of non-insulin dependent diabetes mellitus, a prospective follow-up study was performed of a cohort, initially examined in a population survey on cardiovascular risk factors. The survey was conducted from 1975 to 1978 in the Netherlands among 5700 men and women aged 20 to 65. In 1988 a questionnaire on the prevalence of chronic diseases, including diabetes mellitus, was sent to all living participants of the initial survey. The general practitioners of the persons who indicated to have diabetes mellitus were asked to confirm the diagnosis. Diabetes mellitus was defined as current use of oral hypoglycemic drugs or insulin. After exclusion of the prevalent cases at the initial survey, 65 incident confirmed cases remained. All others responding to the questionnaire served as controls. The incidence of diabetes mellitus was associated with body mass index, use of diuretics, systolic and diastolic blood pressure. After adjustment for age and body mass index systolic and diastolic blood pressure were still associated with the incidence of non-insulin dependent diabetes mellitus in men; relative risks 1.28 (95% confidence interval 1.06-1.54) and 1.40 (95% CI 1.06-1.85) per 10 mmHg respectively. For women, only the relative risk associated with the use of diuretics remained statistically significant (2.26, 95% CI 1.04-4.90). This probably reflects the risk of (treated) hypertension: adjusted for blood pressure, the relative risk lost statistical significance. These findings suggest that elevated blood pressure is a risk for the development of non-insulin dependent diabetes mellitus (NIDDM). This supports the view that NIDDM and hypertension may have a similar origin

Optimalisatie Vissenmeetnet II MWTL KRW-proof

Om de visstand in de Nederlandse grote rivieren te kunnen beoordelen, worden ieder jaar routinematige bemonsteringen uitgevoerd. Deze gegevens worden verzameld ten behoeve van beleidsvorming en evaluatie van het Ministerie van Landbouw, Natuurbeheer en Voedselveiligheid (LNV, Directie Visserij) en het Ministerie van Verkeer en Waterstaat. Deze monitoring wordt uitgevoerd in het kader van het project Biologische Monitoring Zoete Rijkswateren, onderdeel van de Monitoring van de Waterstaatkundige Toestand des Lands (MWTL) van Rijkswaterstaat (RIZA). Deze monitoring heeft tot doel om inzicht te krijgen in de ruimtelijke ontwikkelingen in samenstelling en relatieve omvang van de visbestanden over langjarige perioden, met doel om de toestand van waterlichamen te beoordelen

Presence of pulsations and reproducibility of waveform recording in the umbilical and left portal vein in normal pregnancies

Reproducibility and inter‐observer variability of intra‐ and extra‐abdominal umbilical venous flow velocity and left portal venous flow velocity as well as heart‐synchronous waveform pulsations in these vessels were studied in 23 women at 34–38 weeks of normal pregnancy. Limited reproducibility, expressed by large intra‐patient coefficients and limits of agreement between two observers, was established for all standardized recording sites. Pulsations, defined as negative venous deflections of at least 10% of the mean velocity, were demonstrated at all locations ranging from 19.6% of the measurements at the free‐floating loop of the umbilical vein to 78.4% of the measurements at the left portal vein. The present study shows that the limited reproducibility of venous flow velocity waveforms should be taken into consideration, and that the presence of pulsations can be demonstrated in normal late pregnancy.
