Background: Hip fracture is associated with high mortality. Cardiovascular disease and other comorbidities requiring long-term anticoagulant medication are common in these mostly elderly patients. The objective of our observational cohort study of patients undergoing surgery for hip fracture was to study the association between preoperative use of low-dose acetylsalicylic acid (LdAA) and intraoper
Chronic obstructive pulmonary disease (COPD) is characterized by chronic inflammation of the airways. In the majority of cases, the inflammation is triggered by tobacco smoke. Smoking also affects the pathogenesis of inflammatory bowel disease (IBD), protecting against ulcerative colitis (UC) and promoting development of Crohn's disease (CD). The present study was undertaken to investigate occurre
Background: Walking and cycling to school are one source of regular physical activity. The aim of this two years observational study in pre-pubertal children was to evaluate if walking and cycling to school was associated with higher total amount of physical activity and larger gain in bone mineral content (BMC) and bone width than when going by car or bus. Methods: 133 boys and 99 girls aged 7-9
Background: Vitamin A may have some influence on the immune system, but the role in allergy modulation is still unclear. Objective: To clarify whether high levels of retinoic acid (RA) affects allergic response in vivo, we used a murine experimental model of airway allergic disease. Methods: Ovalbumin (OVA)-immunization/OVA-challenge (OVA/OVA) and house dust mite (HDM)-immunization/HDM-challenge (
Objective To estimate the diagnostic accuracy and interobserver agreement in predicting intracavitary uterine pathology at offline analysis of three-dimensional (3D) ultrasound volumes of the uterus. Methods 3D volumes (unenhanced ultrasound and gel infusion sonography with and without power Doppler, i.e. four volumes per patient) of 75 women presenting with abnormal uterine bleeding at a bleeding
Objective: The purpose of this study was to describe procedural changes in hospital incident investigations and show the consequences of these changes over time. Methods: A two-stage method was used. First component of the study was a content analysis of 87 incident investigations conducted 1995-2014 by the regulatory authority after adverse events in a Swedish university hospital. Second compone
Norovirus (NoV) is a leading cause of gastroenteritis and genotype II.4 (GII.4) is responsible for the majority of nosocomial NoV infections. Our objective was to examine whether sequencing of the capsid gene might be a useful tool for the hospital outbreak investigation to define possible transmission routes. All NoV positive samples submitted from one university hospital during the 2007/8 season
Background: Major intrinsic proteins (MIPs) also named aquaporins form channels facilitating the passive transport of water and other small polar molecules across membranes. MIPs are particularly abundant and diverse in terrestrial plants but little is known about their evolutionary history. In an attempt to investigate the origin of the plant MIP subfamilies, genomes of chlorophyte algae, the sis
Aim This qualitative study was set out to explore oncology outpatient experiences of having cancer, to illuminate coping strategies and to explore perceptions of care and service provided while treated for cancer. Materials and methods Thirty patients undergoing chemotherapy or radiotherapy were consecutively selected for the study in three oncology outpatient clinics in Iceland; mean age was 55 y
This study compared neck range of movement recording using three different methods goniometers (EGM), inclinometers (INC) and a three-dimensional video analysis system (IMG) in simultaneous and synchronized data collection. Twelve females performed neck flexion-extension, lateral flexion, rotation and circumduction. The differences between EGM, INC, and IMG were calculated sample by sample. For fl
Twenty chambers for measurement of soil CO2 efflux were compared against known CO2 fluxes ranging from 0.32 to 10.01 mumol CO2 m(-2) s(-1) and generated by a specially developed calibration tank. Chambers were tested on fine and coarse homogeneous quartz sand with particle sizes of 0.05-0.2 and 0.6 mm, respectively. The effect of soil moisture on chamber measurements was tested by wetting the fine
Here we have examined the enzymes cyclooxygenase (COX)-2 and 15-hydroxyprostaglandin dehydrogenase (15-OH PGDH) in pregnant human cervix. In biopsies taken transvaginally after preterm and term elective cesarean sections and vaginal deliveries, the levels of mRNA coding for COX-2 and 15-OH PGDH were assessed by Northern blotting. The cellular localization of the COX-2 and 15-OH PGDH proteins was d
Several studies have been done in Europe to evaluate exposure to dust and fumes in the rubber industry. However, different aerosol sampling devices have been used which perform differently depending on the environmental conditions and particle size distribution. To compare measurements of rubber dust and fumes among countries and surveys we initiated a field comparison of personal inhalable sample
BACKGROUND: A 40K glycoPEGylated, recombinant Factor VIIa (rFVIIa) bypassing agent (N7-GP) with a prolonged half-life (15 h) compared to rFVIIa was developed as a potential candidate for bleed preventive regimens in patients with hemophilia and inhibitors. OBJECTIVES: To evaluate the safety, pharmacokinetics, and preliminary efficacy of multiple doses of N7-GP in congenital hemophilia A and B pati
Introduction: Assessing left ventricular (LV) systolic function in a rapid and reliable way can be challenging in the critically ill patient. The purpose of this study was to evaluate the feasibility and reliability of, as well as the association between, commonly used LV systolic parameters, by using serial transthoracic echocardiography (TTE). Methods: Fifty patients with shock and mechanical ve
Objective To study the influence of antiinflammatory treatments, including methotrexate (MTX) and tumor necrosis factor (TNF) inhibitors, on antibody response following vaccination using a 7-valent conjugate pneumococcal vaccine in adult patients with established arthritis. Methods. Patients with rheumatoid arthritis (RA) or spondylarthropathy (SpA) (including psoriatic arthritis) were vaccinated
OBJECTIVE. The purpose of this study was to evaluate the potential of a hybrid iterative reconstruction algorithm for improving image quality in craniocervical CT angiography (CTA) and to assess observer performance. SUBJECTS AND METHODS. Thirty patients (mean age, 58 years; range 16-80 years) underwent standard craniocervical CTA (volume CT dose index, 6.8 mGy, 2.8 mSv). Images were reconstructed
