The relationship between selected urinary tract and genital diseases and the risk of bladder cancer »as analyzed using data from a casecontrol study of 364 cases of bladder cancer and 447 controls hospitalized for acute, nonneoplastic, nongenital tract conditions, unrelated to known or suspected risk factors for bladder cancer. Cystitis was reported by 20% of the cases and 8% of the controls, ...

Characteristics of cars, such as mass and age, play a significant role in crash severity, but their effect are difficult to quantify because of the great number of factors altering the outcome of a real world accident. In order to focus on the crashworthiness of cars, we examine risk factors of severity suffered by the drivers involved in two-car accidents recorded by the police between 1996 an...

PURPOSE Lymphotoxin-Alpha (LTA) is a mediator of inflammation which may be associated with the risk of ischemic stroke (IS). Polymorphisms (-252A/G and -804C/A) in the LTA gene have been found to be associated with IS with contradictory results. The present meta-analysis aimed to provide a comprehensive account of the association of (-252A/G and -804C/A) gene polymorphisms of LTA gene with susc...

This dissertation analyzes why some VC-funded high-tech firms do not generate harvesting events for investors through a lucrative sale, either to another company or on the stock exchange. I investigate the effects of three signals of quality on failure and persistence. In the first essay, hypotheses are developed on the unintended consequences of patenting. Disclosure, through patents, exposes ...

Cvyptosporidium spp are a cause of diarrhoea in toddlers. Symptoms and routes of transmission were investigated in a prospective casecontrol study in the city and surroundings of Basel, Switzerland. Twenty one (4.6%) out of 455 children with diarrhoea who attended paediatric and general practices from June to September 1988 were positive for cryptosporidium. The mothers of each case, of two con...

Introduction Intracranial aneurysm (IA) is a regional bulging of intracranial arteries with degenerative changes in arterial walls. Because IA has a high incidence in general public and can cause subarachnoid haemorrhage, a most severe form of stroke with a high mortality rate, after rupture, treatment of IA is socially important. Nonetheless, to date, there is not any medical treatment availab...

The human intellect has an almost irresistible urge to categorize and simplify. Thus, over the years, heart failure has been classified as forward or backward, right or left, compensated or decompensated. These distinctions, which were made primarily on the basis of data obtained from the history and physical examination, provided a conceptual framework for thinking about heart failure and for ...

Epidemiological evidence strongly favors the notion that the risk of cardiovascular disease (CVD) is inversely related to the plasma high-density lipoprotein (HDL) cholesterol concentration.1 Low HDL cholesterol is still predictive of high CVD risk in subjects with low LDL cholesterol,2 as well as during statin treatment.3 These observational data and other studies, which show that HDL particle...

More researchers started using real-time traffic surveillance data, collected from loop/radar detectors (LDs), for proactive crash risk assessment. However, there is a lack of prior studies that investigated the link between real-time traffic data and crash risk of reduced visibility related (VR) crashes. Two issues that have not explicitly been addressed in prior studies are; (1) the possibili...
