BACKGROUND AND AIM: Gastric and enteric Helicobacter species have been associated with the pathogenesis of some extragastric diseases. METHODS: We retrospectively investigated the presence of DNA of Helicobacter species in samples of the cancer and the surrounding tumour-free liver tissues of patients with hepatocellular carcinoma (HCC, n=12) and cholangiocarcinoma (CC, n=13). The patients were fr
Three years of adjuvant imatinib therapy are recommended for patients with GI stromal tumor (GIST) with high-risk features, according to survival findings in the Scandinavian Sarcoma Group XVIII/AIO (Arbeitsgemeinschaft Internistische Onkologie) trial. To investigate whether the survival benefits have persisted, we performed the second planned analysis of the trial.
Thermodynamic formulation of elastoplastic or viscoplastic models using the internal variable approach currently does not include models using the plastic work as a hardening variable. This means that many realistic material models do not fit into the current thermodynamic framework. An approach to extend the thermodynamic framework to include models where plastic work is used as a hardening varia
There has been a great advance in our knowledge of the role that thrombophilic factors play in the risk of venous thromboembolic events (VTE). However, the effect of lifestyle factors on VTE has been inadequately explored in large scale studies of women. This cohort study comprised one thousand native Swedish women for each age year between 25 and 64 inclusive (total = 40 000) drawn from the South
BACKGROUND: Systems providing computer-based analysis of the resting electrocardiogram (ECG) seek to improve the quality of health care by providing accurate and timely automatic diagnosis of, for example, cardiac rhythm to clinicians. The accuracy of these diagnoses, however, remains questionable. OBJECTIVES: We tested the hypothesis that (a) 2 independent automated ECG systems have better accur
A well functioning societal response to crises is benefited by individuals having adequate skills and knowledge. From a municipal perspective this requires the creation of a learning organization. The objective of this study is to determine whether individual municipal employees, who have the responsibility for preparedness planning, reason and act in ways that promote learning about crises and pr
Type 1 diabetes (T1D) is an autoimmune disease caused by the T cell-mediated destruction of the pancreatic insulin-producing beta cells. Currently there are no widely accepted and standardized assays available to analyse the function of autoreactive T cells involved in T1D. The development of such an assay would greatly aid efforts to understand the pathogenesis of T1D and is also urgently require
ABSTRACT Reports of three cases in which patients' pain was previously inadequately treated prior to referral and how it was addressed in a pain clinic are presented. The impact of polypharmacy on medication adherence, fear of opioids among patients and staff, and of stoicism in pain patients is discussed.
Dyslexia has been shown to affect postural control. The aim of the present study was to investigate the difference in postural stability measured as torque variance in an adult dyslexic group (n=14, determined using the Adult Dyslexia Checklist (ADCL) and nonsense word repetition test) and an adult non-dyslexic group (n=39) on a firm surface and on a foam block and with eyes open and eyes closed.
The increasing test application times required for testing system-on-chips (SOCs) is a problem that leads to higher costs. For modular core based SOCs it is possibly to employ a concurrent test scheme in order to lower the test application times. To allow each core to be tested as a separate unit, a wrapper is inserted for each core, the scan chains at each core are configured into a fixed number
Mercury concentrations in air and in condensed steam coming from fumarolic activity at the Solfatara crater (Phlegraean Fields - Italy) were determined. In the condensed steam, mercury was found mainly associated as Hg-S complexes and showed a flux in the range from 0.9 to 4.5 g day(-1). Using the point monitor technique, high values (up to 690 ng m(-3)) of atmospheric mercury levels were observed
Increased plasma concentrations of small LDL particles denote an atherogenic lipoprotein phenotype (ALP) that is correlated with increased circulating TAG and reduced HDL-cholesterol. Principal component analyses of subfraction concentrations have previously been used in the Swedish population-based Malmö Diet and Cancer (MDC) cohort to identify three independent components, one pattern representi
Endovascular aneurysm repair (EVAR) offers a minimally invasive treatment to patients with improved short-term and similar mid-term results compared to conventional, open repair (OR). EVAR is preferred by patients due to the reduction of surgical trauma. Approximately 20% of patients have aneurysm neck morphology which is inadequate for a standard stent graft and requires the endograft to cross vi
Background: There is a paucity of research on the effects of interactive feedback methods and sustained assessment strategies in formative assessment of students in the workplace. Aims: To investigate the outcome of long-term use of an assessment tool. Methods: Retrospective analysis of summarised assessment tools from 3 years of 464 final-year students in general practice. Quantitative data were
Chebyshev polynomial techniques for solution of singular integral equations leading to square root singularities at the ends of the interval of integration are studied. It is shown that the results are less accurate when a singularity, albeit a weak one, appears between the interval ends. Typical examples are problems involving kinked cracks. Some attempts to improve the accuracy are discussed.
Many reports on living kidney donation describe rapid recovery. In our experience rehabilitation is rather slow. This study aimed to explore self-reported health status among living donors (LDs) three to four weeks and six months post-donation with a longitudinal design. In this study. LDs (n = 112) reported their physical and mental health by responding to a questionnaire before surgery, after th
BACKGROUND: The incidence of acute cardiovascular and cerebrovascular events in patients treated for complicated or uncomplicated peptic ulcer disease (PUD) has not been ascertained completely. METHOD: All patients with in-hospital treatment due to PUD between 1987 and 2007, who did not have any past history of acute or chronic cardiovascular or cerebrovascular disease, were identified through the
