Background: During atrial fibrillation (AF), conventional electrophysiological techniques for assessment of refractory period or conduction velocity of the atrioventricular (AV) node cannot be used. We aimed at evaluating changes in AV nodal properties during administration of tecadenoson and esmolol using a novel ECG-based method. Methods: Fourteen patients (age 58 +/- 8 years, 10 men) with AF we

Abstract in UndeterminedPurpose - The purpose of this paper is to describe and analyse ways of organizing integrated care for older persons in Sweden during the past decade. Design/methodology/approach - The data consist of 62 cases of development work, described in official reports. A meta-analysis of cases was performed, including content analysis of each case. A theoretical framework comprising

ABSTRACT: Excessive neutrophil infiltration is a major component in septic lung injury, although the signaling mechanisms behind pulmonary recruitment of neutrophils in polymicrobial sepsis remain elusive. Herein, we hypothesized that Rho-kinase activity may play a significant role in pulmonary neutrophil recruitment and tissue damage in abdominal sepsis. Male C57BL/6 mice were treated with the Rh

AIMS/HYPOTHESIS: We tested whether gestational diabetes mellitus (GDM) is associated with HLA-DQ genotypes. METHODS: A total of 764 mothers with non-autoimmune (GAD65, insulinoma-associated protein 2 [IA-2] and insulin autoantibody-negative) GDM were ascertained between September 2000 and August 2004 in the population-based Diabetes Prediction in Skåne (DiPiS) study. HLA-DQB1 genotypes were determ

The aim of this paper is to consider how the notion of analyticity can be dealt with in model-theoretical terms. Standard approaches to possible-world semantics allow us to define necessity and logical truth, but analyticity is considerably more difficult to account for. To explain this difficulty, we first provide a simplified sketch of possible-world semantics. After defining necessity and logic

In a series of 450 patients over 70 years of age with displaced fractures of the femoral neck sustained between 1995 and 1997 treatment was randomised either to internal fixation or replacement. Depending on age and level of activity the latter was either a total hip replacement or a hemiarthroplasty. Patients who were confused or bed-ridden were excluded, as were those with rheumatoid arthritis.

BACKGROUND: Studies investigating the importance of social network, empowerment and experiences of stigma on subjective quality of life among persons with mental illness are rare. AIM: This study aimed to investigate beliefs of devaluation/discrimination, actual rejection experiences, empowerment, social network and the relationship of these factors to subjective quality of life among subjects wit

Abstract in UndeterminedBackground: The current management guidelines for pediatric mild head injury (MHI) liberally recommend computed tomography (CT) and frequent admission. Serum protein S100B, currently used in management of adult head injury, has recently shown potential for reducing unnecessary CT scans after pediatric mild head injury. Capillary sampling in children is commonly used when ve

To our knowledge, the assessment of dural sac diameters in patients with adolescent idiopathic scoliosis (AIS) is not reported in the literature. The aim of this study was to find out if, dural ectasia occurs more frequently among patients with AIS, to define cut-off values for dural sac ratio and test the validity of such values. A total of 126 spine MRIs (79 patients with AIS and 47 control subj

BACKGROUND: Depressive disorders are common and disabling. The Lundby Study is a prospective study of a community sample that started in 1947(N=2550). In 1957, 1013 newcomers were added. The latest field investigation was carried out in 1997. AIM: To identify risk factors for depressive disorders. METHOD: The Lundby database contains clinical assessments of the subjects made by psychiatrists. It a

OBJECTIVE:: To describe the characteristics of patients undergoing multiple groin hernia repairs and to identify strategies that prevent further recurrence. SUMMARY BACKGROUND DATA:: Although relatively infrequent, recurrent groin hernias where several repairs have previously been undertaken constitutes a major problem in hernia surgery. Low numbers and heterogeneity have made it difficult to perf

Bovine milk is associated with improved health and reduced risk of several diseases, among them cancer. Milk is a complex mixture of known and unknown components. The components and the mechanisms that contribute to the cancer-preventive effects are largely unknown. We set out to find new peptides in milk and identified ubiquitin (Ub) using matrix-assisted laser desorption ionization-time of fligh

von Willebrand's disease (VWD) is probably the most common bleeding disorder, with some studies indicating that up to 1% of the population may have the condition. Over recent years interest in VWD has fallen compared to that of haemophilia, partly the result of focus on blood-borne diseases such as HIV and hepatitis. Now the time has come to revisit VWD, and in view of this some 60 international p

Type 2 diabetes is triggered by reduced insulin production, caused by genetic and environmental factors such as inflammation originating from the innate immune system. Complement proteins are a component of innate immunity and kill non-self cells by perforating the plasma membrane, a reaction prevented by CD59. Human pancreatic islets express CD59 at very high levels. CD59 is primarily known as a

OBJECTIVE: The purpose of this study was to assess the effectiveness of electronic fetal monitoring (EFM) alone and with additional ST analysis (EFM + ST) in laboring women with a singleton term pregnancy that is in cephalic presentation in the prevention of metabolic acidosis by the application of individual patient data metaanalysis. STUDY DESIGN: We conducted an individual patient data metaanal

To investigate persons with dementia and their informal caregivers' views of inter-sectoral information, communication and collaboration throughout the trajectory of dementia care, in eight European countries.

PURPOSE: Ventilation/perfusion tomography (V/PSPECT), with new interpretation criteria and newer tracers for ventilation imaging, has markedly improved the diagnostic yield in acute pulmonary embolism (PE). Here, we evaluated the diagnostic performance of perfusion SPECT (PSPECT) without ventilation imaging. METHODS: We studied 152 patients with clinically suspected PE who had been examined with b
