Cardiovascular magnetic resonance reference values of mitral and tricuspid annular dimensions : the UK Biobank cohort

Background: Mitral valve (MV) and tricuspid valve (TV) apparatus geometry are essential to define mechanisms and etiologies of regurgitation and to inform surgical or transcatheter interventions. Given the increasing use of cardiovascular magnetic resonance (CMR) for the evaluation of valvular heart disease, we aimed to establish CMR-derived age- and sex-specific reference values for mitral annula

Assessment of Amide proton transfer weighted (APTw) MRI for pre-surgical prediction of final diagnosis in gliomas

PURPOSE: Radiological assessment of primary brain neoplasms, both high (HGG) and low grade tumors (LGG), based on contrast-enhancement alone can be inaccurate. We evaluated the radiological value of amide proton transfer weighted (APTw) MRI as an imaging complement for pre-surgical radiological diagnosis of brain tumors.METHODS: Twenty-six patients were evaluated prospectively; (22 males, 4 female

[11C]PIB amyloid quantification : effect of reference region selection

Background: The standard reference region (RR) for amyloid-beta (Aβ) PET studies is the cerebellar grey matter (GMCB), while alternative RRs have mostly been utilized without prior validation against the gold standard. This study compared five commonly used RRs to gold standard plasma input-based quantification using the GMCB. Methods: Thirteen subjects from a test–retest (TRT) study and 30 from a

Aims: To describe and compare perceptions of collaboration between care providers on the part of three groups of Registered Nurses working in municipal care and having particular responsibility concerning the care of frail older people with intellectual disability (ID); and, furthermore, to investigate the presence of and compliance with guidelines for the coordination of care. Design: National su

Diagnostic center for primary care patients with nonspecific symptoms and suspected cancer : compliance to workflow and accuracy of tests and examinations

OBJECTIVE: To evaluate compliance to workflow and accuracy of tests in Sweden's first fast-track referral pathway for patients with nonspecific symptoms and suspected cancer (SCAN).DESIGN: Prospective cohort study with consecutive inclusion of patients referred to the diagnostic center (DC).SETTING: Patients with nonspecific symptoms were examined in primary care according to a protocol including

Efficacy of umeclidinium/vilanterol according to the degree of reversibility of airflow limitation at screening : a post hoc analysis of the EMAX trial

Background: In patients with chronic obstructive pulmonary disease (COPD), the relationship between short-term bronchodilator reversibility and longer-term response to bronchodilators is unclear. Here, we investigated whether the efficacy of long-acting bronchodilators is associated with reversibility of airflow limitation in patients with COPD with a low exacerbation risk not receiving inhaled co

Isolation of human complex-forming glycoprotein, heterogeneous in charge (protein HC), and its IgA complex from plasma. Physiochemical and immunochemical properties, normal plasma concentration

Human complex-forming glycoprotein, heterogeneous in charge (protein HC) has previously been isolated from urine and immunochemically shown to be present in low and high molecular weight forms in blood plasma (Tejler, L., and Grubb, A. O. (1976) Biochim. Biophys. Acta 439, 82-94). In the present work, the major low and high molecular weight forms of the protein were isolated from plasma by immunos

Circulating tumor cells in patients with advanced urothelial carcinoma of the bladder : Association with tumor stage, lymph node metastases, FDG-PET findings, and survival

Background: There are currently no methods in clinical use that can detect early systemic dissemination of urothelial tumor cells. Objective: To evaluate measurement of circulating tumor cells (CTCs) as a biomarker for disseminated disease in patients with advanced bladder cancer. Design, setting, and participants: Between March 2013 and October 2015, 88 patients were prospectively included in the

Posttraumatic bone marrow lesion volume and knee pain within 4 weeks after anterior cruciate ligament injury

Context: After an anterior cruciate ligament (ACL) injury, a majority of patients have a traumatic bone marrow lesion (BML, or bone bruise). The clinical relevance of posttraumatic lesions remains unclear. Objective: To explore the cross-sectional associations between traumatic BML volume and self-reported knee pain and symptoms among individuals within 4 weeks of ACL injury. Design: Cross-section

Low Serum DHEAS Predicts Increased Fracture Risk in Older Men : The MrOS Sweden Study

The adrenal-derived hormones dehydroepiandrosterone (DHEA) and its sulfate (DHEAS) are the most abundant circulating hormones and their levels decline substantially with age. DHEAS is considered an inactive precursor, which is converted into androgens and estrogens via local metabolism in peripheral target tissues. The predictive value of serum DHEAS for fracture risk is unknown. The aim of this s

Orthostatic Hypotension and Elevated Resting Heart Rate Predict Low-Energy Fractures in the Population : The Malmö Preventive Project

BACKGROUND: Autonomic disorders of the cardiovascular system, such as orthostatic hypotension and elevated resting heart rate, predict mortality and cardiovascular events in the population. Low-energy-fractures constitute a substantial clinical problem that may represent an additional risk related to such autonomic dysfunction.AIMS: To test the association between orthostatic hypotension, resting

Measures of Physical Performance and Muscle Strength as Predictors of Fracture Risk Independent of FRAX, Falls, and BMD : A Meta-Analysis of the Osteoporotic Fractures in Men (MrOS) Study

Measures of muscle mass, strength, and function predict risk of incident fractures, but it is not known whether this risk information is additive to that from FRAX (fracture risk assessment tool) probability. In the Osteoporotic Fractures in Men (MrOS) Study cohorts (Sweden, Hong Kong, United States), we investigated whether measures of physical performance/appendicular lean mass (ALM) by DXA pred

Spectral light absorption by ambient aerosols influenced by biomass burning in the Amazon Basin. I : Comparison and field calibration of absorption measurement techniques

Spectral aerosol light absorption is an important parameter for the assessment of the radiation budget of the atmosphere. Although on-line measurement techniques for aerosol light absorption, such as the Aethalometer and the Particle Soot Absorption Photometer (PSAP), have been available for two decades, they are limited in accuracy and spectral resolution because of the need to deposit the aeroso

BCG skin reactions by 2 months of age are associated with better survival in infancy : A prospective observational study from Guinea-Bissau

Introduction Receiving Bacille Calmette-Guérin (BCG)-Denmark vaccine at birth has been associated with ∼40% reductions in all-cause neonatal mortality. We evaluated determinants of BCG skin reaction characteristics by age 2 months and tested the association with subsequent mortality. Methods Prospective observational study amalgamating five trials providing BCG-at-birth that were conducted between

Being a ‘strategist’ : Communication practitioners, ‘strategic work’, and power effects of the strategy discourse

PurposeThe paper analyzes power effects of the strategy discourse to create a more profound understanding of how strategy seen as a discourse constitutes certain identities and practices among communication practitioners. The following two research questions has been posed to concretize the overall aim of the study: 1) What has the strategy discourse meant for practitioners understanding of themse

Why Distinguish Between Statistics and Mathematical Statistics–The Case of Swedish Academia

A separation between the academic subjects statistics and mathematical statistics has existed in Sweden almost as long as there have been statistics professors. The same distinction has not been maintained in other countries. Why has it been kept for so long in Sweden, and what consequences may it have had?In May 2015, it was 100 years since Mathematical Statistics was formally established as an a
