In a prospective study all positive phlebographies within the well-defined population of the city of Malmö, Sweden, during 1987 were studied in order to determine the incidence of deep venous thrombosis (DVT). Epidemiological data were analysed for the detection of patient groups at increased risk of DVT. The incidence was found to be equal for both sexes,(More)
Alien predators are widely considered to be more harmful to prey populations than native predators. To evaluate this expectation, we conducted a meta-analysis of the responses of vertebrate prey in 45 replicated and 35 unreplicated field experiments in which the population densities of mammalian and avian predators had been manipulated. Our results showed(More)
OBJECTIVE To elucidate whether there is an association between symphyseal distention, circulating relaxin levels and pelvic pain in pregnancy. METHODS Serum relaxin and symphyseal width were assessed in 19 consecutive referral cases with severe pelvic pain at 35 weeks of pregnancy and in a cohort of 49 women at 12 and 35 weeks of pregnancy. The referral(More)
OBJECTIVE The aim of the study was to evaluate the outcome of two different methods of cesarean section (CS). DESIGN The study was designed as a prospective, randomized, controlled trial. SETTING All CS were performed at the University Hospital in Uppsala, Sweden. POPULATION Fifty women admitted to hospital for a first elective CS were consecutively(More)
Reliable measurement of different tissue volumes in the living brain is of great importance for human brain research. In this article, we report on the inter- and intraoperator reliability and scan-rescan reproducibility of segmented intracranial tissue volumes from MR images using the image analysis software suite BRAINS. The absolute data of tissue volume(More)
Social differences in late fetal death and infant mortality were examined in a population-based prospective study. All singletons born to Nordic citizens in Sweden 1985-86 were included, 185,156 births in all. The overall rates of late fetal death and infant mortality were 3.5 and 5.3 per 1000 respectively. Socio-economic status of the household (SES) and(More)
1. Nonlethal predation effects may have stronger impacts on prey populations than direct predation impacts, and this should also apply to intraguild predation. The consequences of such interactions become especially important if invasive, and potentially destructive alien predators act as intraguild prey. 2. We studied the predation-risk impacts of a(More)
Amphibians are undergoing enigmatic global declines variously attributed to a complex web of anthropogenic forces. Alien predators pose a fundamental threat to biodiversity generally that is predicted to be most acute in island ecosystems. While amphibian eggs and tadpoles are vulnerable to aquatic predators, the effect of predators on adult, reproducing(More)
The aim of this study is to investigate predictors for mortality in two age groups, 75-84 years old and 85 years and older. Interviews were carried out on 161 community-based persons aged 75-84 and 260 persons aged 85 and over. Predictors for mortality 4 years later were analyzed using logistic regression. Different models to predict mortality were found(More)
OBJECTIVE To determine the risk of subsequent cancer in patients with deep venous thrombosis confirmed by venography. DESIGN Follow up of all patients who had venography for suspected deep venous thrombosis during 1984-88. Patients were traced through a cancer registry up to 1 January 1991. SUBJECTS 4399 patients who had phlebography in one hospital. (More)
