Occupational asbestos exposure and risk of esophageal, gastric and colorectal cancer in the prospective Netherlands Cohort Study

The evidence for an association between occupational asbestos exposure and esophageal, gastric and colorectal cancer is limited. We studied this association specifically addressing risk differences between relatively low and high exposure, risk associated with cancer subtypes, the influence of potential confounders and the interaction between...

Toenail selenium status and the risk of Barrett's esophagus: The Netherlands Cohort Study

Objective: To investigate the association between selenium and the risk of Barrett's esophagus (BE), the precursor lesion of esophageal adenocarcinoma. Methods: Data from the prospective Netherlands Cohort Study were used. This cohort study was initiated in 1986, when 120,852 subjects aged 55-69 years completed a questionnaire on dietary habits...

A compendium of familial relative risks of cancer among first degree relatives: A population-based study

Familial clustering of cancer is expected to occur at practically all anatomical sites. However, few studies have had sufficient size to investigate different sites simultaneously and with adjustment for confounders. We evaluated familial clustering in the Netherlands Cohort Study in which 120,852 men and women, aged 55-69 years in 1986 were...

Dietary acrylamide intake is not associated with gastrointestinal cancer risk

Acrylamide is a probable human carcinogen that was detected in several heat-treated foods, such as French fries and crisps, in 2002. Prospective studies are needed on acrylamide and human cancer risk. We prospectively investigated the association between acrylamide and gastrointestinal cancer risk. In 1986, 120,852 men and women (aged 55-69 y)...

Infrared tympanic temperature and ear canal morphology

Several publications indicate that the infrared tympanic temperature (IRTT) underestimates the core temperature of the body when the ear canal is long, curvy and narrow. In order to quantify these observations, a study was performed in 10 subjects. The IRTT was determined and compared to the oesophageal temperature (Tes), taken as the reference...

Finger cold-induced vasodilatation during hypothermia, hyperthermia and at thermoneutrality

BACKGROUND: Exposure of the fingers to severe cold leads to cold-induced vasodilation (CIVD). The influence of ambient temperature on the CIVD-response is well understood and documented, but the response of CIVD to hyperthermia and mild hypothermia has rarely been investigated. METHODS: To investigate the influence of body thermal status on the...

Assessment of human exposure to fumonisin B1

Fumonisin B1 is currently regarded as the most significant mycotoxin produced by Fusarium spp. It has carcinogenic properties and may play a role in the etiology of human esophageal cancer. The human population is exposed to fumonisin B1 primarily by intake of fumonisin B1-contaminated maize. Maize consumed in the Netherlands is imported from...

Structure, localization and action of a novel inhibitory neuropeptide involved in the feeding of Lymnaea

A neuropeptide that strongly inhibits the spontaneous contractions of the oesophagus in Lymnaea has been characterized as GAPRFVamide. Direct mass spectrometry of nervous tissues and immunocytochemical studies show that the peptide is synthesized by neurones in the buccal ganglia and transported to the oesophagus via the dorso-buccal nerve. In...

Comparison of four noninvasive rewarming methods for mild hypothermia

Four noninvasive rewarming techniques for mildly hypothermic subjects were compared. Seven subjects were cooled in a water bath of 15°C for 2 h to an average esophageal temperature (Tes) of 36°C. Thereafter, the subjects were rewarmed by immersion of the body in a water bath of 42°C (Method 1), the body but not the extremities in water of 42°C ...

Hemostasis and fibrinolysis in severe liver failure and their relation to hemorrhage

In a study of severe, decompensated liver failure, we tried to find a correlation between hemorrhage and parameters of hemostasis and fibrinolysis. Three groups of patients were studied: alcoholic cirrhosis; nonalcoholic cirrhosis, and acute liver failure without known prior liver disease. The two cirrhotic groups did not differ significantly...
