Enhanced and resumed GB virus C replication in HIV-1-infected individuals receiving HAART.

In patients co-infected with HIV-1 and GB virus C (GBV-C), the disappearance of GBV-C RNA has been associated with accelerated disease progression. We studied longitudinal GBV-C viral titres in 28 HIV-1/GVB-C co-infected individuals receiving HAART. During HAART, median GBV-C RNA titres increased from 95 to 6000 copies/ml (P < 0.001). In patients interrupting HAART, GBV-C-RNA titres decreased as H

Protease activation, pancreatic leakage, and inflammation in acute pancreatitis: differences between mild and severe cases and changes over the first three days.

BACKGROUND/AIMS: The pathophysiology of acute pancreatitis (AP) may be studied using markers of protease activation (active carboxypeptidase B (aCAP), the activation peptide of carboxypeptidase B (CAPAP)), leakage of pancreatic enzymes (trypsinogen-2, procarboxypeptidase B (proCAP), amylase), and inflammation (monocyte chemoattractant protein-1 (MCP-1), CRP). METHODS: This prospective study includ

Hypoxia triggers a proangiogenic pathway involving cancer cell microvesicles and PAR-2-mediated heparin-binding EGF signaling in endothelial cells.

Highly malignant tumors, such as glioblastomas, are characterized by hypoxia, endothelial cell (EC) hyperplasia, and hypercoagulation. However, how these phenomena of the tumor microenvironment may be linked at the molecular level during tumor development remains ill-defined. Here, we provide evidence that hypoxia up-regulates protease-activated receptor 2 (PAR-2), i.e., a G-protein-coupled recept

Inferior physical performance test results of 10,998 men in the MrOS Study is associated with high fracture risk.

Background: most fractures are preceded by falls.Objective: the aim of this study was to determine whether tests of physical performance are associated with fractures.Subjects: a total of 10,998 men aged 65 years or above were recruited.Methods: questionnaires evaluated falls sustained 12 months before administration of the grip strength test, the timed stand test, the six-metre walk test and the

Videoconference brings Durban closer to the classroom

There is something wrong with the sound. In Durban, Lena Ek, the Swedish minister for the environment, was ready to answer questions from students, in a shared Google document, communicators and teachers worked together to sort out the technical problems, while a couple of details about the participants were edited by a third participant.

Impact of intrasac thrombus and a patent inferior mesenteric artery on EVAR outcome.

PURPOSE: To assess the significance of a patent inferior mesenteric artery (IMA) and presence of intrasac thrombus on the outcome of endovascular aneurysm repair (EVAR) for infrarenal abdominal aortic aneurysm (AAA). METHODS: Between June 2004 and June 2007, 114 AAA patients (100 men; mean age 75 years, range 56-87) treated electively with a bifurcated stent-graft were assessed with computed tomog

Job satisfaction and associated variables among nurse assistants working in residential care.

Background: While the work situation for nurse assistants in residential care is strenuous, they themselves often state that they are satisfied with their job. More knowledge is clearly needed of the interrelationship of variables associated with job satisfaction. This study aims to investigate job satisfaction and explore associated variables among nurse assistants working in residential care.

Positive Experience of a Mobile Radiography Service in Nursing Homes.

Background: For elderly people living in nursing homes, a transport to hospital for a radiological examination can lead to increased anxiety, disorientation and other problems related to the new environment. Objective: To investigate the usefulness of a mobile radiography service for radiological assessment of patients in nursing homes from the patient and staff perspectives. Methods: Lightweight

Risk predictions for individual patients from logistic regression were visualized with bar-line charts.

OBJECTIVE: The interface of a computerized decision support system is crucial for its acceptance among end users. We demonstrate how combined bar-line charts can be used to visualize predictions for individual patients from logistic regression models. STUDY DESIGN AND SETTING: Data from a previous diagnostic study aiming at predicting the immediate risk of acute coronary syndrome (ACS) among 634 p

Discursive mechanisms and human agency in language policy formation : negotiating bilingualism and parallel language use at a Swedish university

In the wake of the enactment of Sweden’s Language Act in 2009 and in the face of the growing presence of English, Swedish universities have been called upon by the Swedish Higher Education Authority to craft their own language policy documents. This article focuses on the discursive negotiation of institutional bilingualism by a language policy committee at one Swedish university during the proces

Phosphate-containing dialysis solution prevents hypophosphatemia during continuous renal replacement therapy.

Background: Hypophosphatemia occurs in up to 80% of the patients during continuous renal replacement therapy (CRRT). Phosphate supplementation is time-consuming and the phosphate level might be dangerously low before normophosphatemia is re-established. This study evaluated the possibility to prevent hypophosphatemia during CRRT treatment by using a new commercially available phosphate-containing

Rho-kinase regulates adhesive and mechanical mechanisms of pulmonary recruitment of neutrophils in abdominal sepsis.

We hypothesized that Rho-kinase signaling plays a role in mechanical and adhesive mechanisms of neutrophil accumulation in lung. Male C57BL/6 mice were treated with the Rho-kinase inhibitor Y-27632 prior to cecal ligation and puncture (CLP). Lung levels of myeloperoxidase (MPO) and histological tissue damage were determined 6h and 24h after CLP. Expression of Mac-1 and F-actin formation in neutrop

Tobacco Use in Relation to Chronic Pain: Results from a Swedish Population Survey.

Objective. To study the relationship between tobacco use and pain intensity. Design. An age-stratified cross-sectional study was carried out in southern Sweden in 2005. Sample. The population study consists of 384 people, aged 18-102 years, with chronic pain. Measurement. Data collection took place by means of a postal questionnaire. Comparisons of pain intensity were made between smokers and nons

The t(X;6) in subungual exostosis results in transcriptional deregulation of the gene for insulin receptor substrate 4.

Subungual exostosis is a benign bone- and cartilage-forming tumor known to harbour a pathognomonic t(X;6)(q22;q13-14). Using global gene expression analysis and quantitative real-time PCR we could show that this translocation results in increased expression of the IRS4 gene, presumably due to disruption and/or exchange of regulatory sequences with the translocation partner, the COL12A1 gene. A cor
