Beta amyloid is one of the major histopathological hallmarks of Alzheimer's disease. We recently reported in vivo imaging of amyloid in 16 Alzheimer patients, using the PET ligand N-methyl[11C]2-(4'-methylaminophenyl)-6-hydroxy-benzothiazole (PIB). In the present study we rescanned these 16 Alzheimer patients after 2.0 +/- 0.5 years and have described the(More)
BACKGROUND The contribution of hereditary and environmental factors to the development of abdominal aortic aneurysms (AAAs) is still partly unknown. The aim of this study was to analyze the role of these factors in a large population-based sample of twins. METHODS The Swedish Twin Registry, containing data on twins born in the country since 1886, was(More)
OBJECTIVE The most commonly used predictor of rupture of an abdominal aortic aneurysm (AAA) is the diameter; however, this does not estimate the true risk for each patient. Why women with AAAs have an increased growth rate, weaker aortic wall, and increased risk for rupture is yet unclear. It is likely that geometrical and biomechanical properties(More)
OBJECTIVE To investigate the prevalence of thoracic aortic aneurysms (TAA) in patients with abdominal aortic aneurysms (AAA). BACKGROUND Different disease profiles between men and women treated for AAA have been reported. Reports regarding causes of death for treated AAA patients have shown an increased risk of death because of other aneurysms for women,(More)
BACKGROUND Several studies have reported a familial clustering of abdominal aortic aneurysm (AAA) supporting that AAA is an inheritable disease, but few population-based studies can be found. Possible gender differences regarding hereditary patterns have been reported. OBJECTIVE The aim of this study was to investigate the risk of developing an AAA for(More)
BACKGROUND A recent report unexpectedly revealed that one-fourth of abdominal aortic aneurysm (AAA) patients also have an aneurysm in the thoracic aorta (TAA). It remains to be investigated which AAA patients have a higher risk of also developing TAAs. The aim of this study was to identify possible differences in the risk factor profile in AAA patients with(More)
Clinical experience and previous studies indicate that low socioeconomic positions are overrepresented in trauma populations. The reason for this social variation in injury risk is likely to be multifactorial. Both individual and environmental sources of explanation are plausible to contribute. We investigated the impact of the influence of socioeconomic(More)
BACKGROUND The trauma patient sustains numerous potentially harmful insults that may contribute to a notable risk of acute kidney injury (AKI). The aim of this study was to investigate the incidence of and to identify risk factors for AKI in severely injured trauma patients admitted to the intensive care unit (ICU). The patients were followed up for 1 year(More)
The impact of host factors, such as gender and co-morbidity, on mortality after trauma has been debated. Quantification of risk factors is dependent on methodological considerations including follow-up time, definitions and adjustment of potential confounders. Optimal follow-up time of trauma patients remains to be elucidated. We investigated the impact of(More)
OBJECTIVE To evaluate the quality of anaesthesia for Caesarean sections at Muhimbili National Hospital, Dar es Salaam, Tanzania. METHOD We developed an instrument consisting of 40 quality indicators using an expert group process based on the existing literature. Using the instrument, we observed 50 Caesarean sections. Twenty-eight of the indicators were(More)
