Effects of the glucagon-like peptide-1 receptor agonist liraglutide on 24-h ambulatory blood pressure in patients with type 2 diabetes and stable coronary artery disease: a randomized, double-blind, placebo-controlled, crossover study.

Objective: The glucagon-like peptide-1 receptor agonist liraglutide has been shown to reduce blood pressure (BP) in clinical trials using office BP measurements. However, the effects of liraglutide on 24-h BP and on the diurnal variation in BP have not been explored sufficiently.

Methods: Forty-one patients with type 2 diabetes and stable coronary artery disease were randomized to receive liraglutide or placebo to a backbone therapy of metformin in this double-blind, placebo-controlled 12 along with 12 weeks crossover study.

Effects of Liraglutide on Heart Rate and Heart Rate Variability: A Randomized, Double-Blind, Placebo-Controlled Crossover Study.

Objective: Reduced heart rate variability (HRV) and increased heart rate (HR) have been associated with cardiovascular mortality. Glucagon-like peptide 1 receptor agonists (GLP-1 RAs) increase HR, and studies have suggested that they may reduce HRV. We examined the effect of the GLP-1 RA liraglutide on HRV and diurnal variation of HR in overweight patients with newly diagnosed type 2 diabetes (T2D) and stable coronary artery disease (CAD).

Effects of the glucagon-like peptide-1 receptor agonist liraglutide on systolic function in patients with coronary artery disease and type 2 diabetes: a randomized double-blind placebo-controlled crossover study.

Background: Patients with type 2 diabetes (T2D) and coronary artery disease (CAD) have increased risk of cardiac dysfunction. The diabetic heart is characterized by increased fatty acid oxidation and reduced glucose uptake resulting in reduced cardiac efficiency. Glucagon-like peptide-1 (GLP-1) has shown to increase myocardial glucose uptake and to improve myocardial function.

Effect of propranolol on survival in patients with decompensated cirrhosis: a nationwide study based Danish patient registers.

Background & Aims: We assessed the impact of propranolol on death, risk of hepatorenal syndrome and peritonitis in patients with cirrhosis.

Methods: This study was a retrospective observational study and data were retrieved from Danish databases. We used our own criteria to stratify the patients into groups of patients with mildly decompensated cirrhosis or severely decompensated cirrhosis.

Penile density and globally used chemicals in Canadian and Greenland polar bears.

Industrially produced chemicals have been a major environmental concern across our entire Globe since the onset of rapid industrial development around the early 1900. Many of the substances being used are known to be endocrine disrupting chemicals (EDCs) and are also known to be long-range dispersed and to biomagnify to very high concentrations in the tissues of Arctic apex predators such as polar bears (Ursus maritimus). A major concern relating to EDCs is their effects on vital organ-tissues such as bone and it is possible that EDCs represent a more serious challenge to the species' survival than the more conventionally proposed prey reductions linked to climate change.

Cortical Thickness Changes Associated with Photoparoxysmal Response.

Photoparoxysmal response (PPR) is an EEG trait of spike and spike-wave discharges in response to photic stimulation that is closely linked to idiopathic generalized epilepsy (IGE). In our previous studies we showed that PPR is associated with functional alterations in the occipital and frontal cortices. The aim of the present study was to determine structural changes associated with PPR.

Mortality, cancer, and comorbidities associated with chronic pancreatitis: a Danish nationwide matched-cohort study.

Background & Aims: We aimed to assess the risk of death, cancer, and comorbidities among patients with alcoholic and nonalcoholic chronic pancreatitis (CP).

Methods: We performed a nationwide retrospective cohort study, collecting data from Danish registries from 1995 through 2010. We evaluated the prevalences and incidences of death, cancers, and comorbidities among subjects with CP (cases) compared with age- and sex-matched individuals (controls).

The impact of recombinant parathyroid hormone on malignancies and mortality: 7 years of experience based on nationwide Danish registers.

Unlabelled: We used Danish registers to identify patients with osteoporosis, who had been treated with parathyroid hormone and evaluated the probability of developing cancer. We did not find an increased risk of cancer among the patients treated with parathyroid hormone.

Introduction: We evaluated the incidences of malignancies and mortality in osteoporotic patients treated with rPTH.

The risk of fractures among patients with cirrhosis or chronic pancreatitis.

Background & Aims: Cirrhosis and chronic pancreatitis (CP) are accompanied by inflammation and malnutrition. Both conditions can have negative effects on bone metabolism and promote fractures. We evaluated the risk of fractures among patients with CP or cirrhosis and determined the effect of fat malabsorption on fracture risk among patients with CP.

Do patients care about higher flexion in total knee arthroplasty? A randomized, controlled, double-blinded trial.

Background: Little information exists to support that patients care about flexion beyond what is needed to perform activities of daily living (ADL) after Total knee arthroplasty (TKA). The purpose of this study was to investigate if the achievement of a higher degree of knee flexion after TKA would result in a better patient perceived outcome.

Methods: The study is a randomized, double-blinded, controlled trial in which 36 patients (mean age: 67.

The epidemiology of Schmorl's nodes and their correlation to radiographic degeneration in 4,151 subjects.

Purpose: Schmorl's nodes (SNs) are commonly seen in vertebral imaging of the normal adult population referred for different reasons and are duly noted by the radiologist. However, little is known about their etiology: either SNs are perceived as largely inert developmental or congenital herniations of disc tissue into weak areas of the vertebral end-plates, or they are perceived as a common pathological pathway of different adverse and general factors such as malignancy, trauma, infection, osteoporosis, Paget's disease and so forth. A commonly accepted morphological definition of what precisely constitute SNs does not exist, and consequently prevalences vary wildly in the literature.

Fast-track hip and knee arthroplasty: clinical and organizational aspects.

Fast-track hip and knee arthroplasty aims at giving the patients the best available treatment at all times, being a dynamic entity. Fast-track combines evidence-based, clinical features with organizational optimization including a revision of traditions resulting in a streamlined pathway from admission till discharge – and beyond. The goal is to reduce morbidity, mortality and functional convalescence with an earlier achievement of functional milestones including functional discharge criteria with subsequent reduced length of stay and high patient satisfaction.

The alignment of the knee joint in relationship to age and osteoarthritis: the Copenhagen Osteoarthritis Study.

Introduction: The aim of the present study was to describe the changes in the axis of the knee joint in both radiologically osteoarthritic and non-osteoarthritic knees, on the basis of angles measurable in standardized clinical short knee radiographs, in a cross sectional study of an epidemiological cohort.

Design: From the third inclusion of the Copenhagen City Heart Study, 4,151 subjects were selected for standardized radiography of the knees. After censuring the inclusion, the resulting cohort was comprised of 3,488 individuals.

Do we need a gender-specific total knee replacement? A randomised controlled trial comparing a high-flex and a gender-specific posterior design.

The purpose of this study was to investigate whether a gender-specific high-flexion posterior-stabilised (PS) total knee replacement (TKR) would offer advantages over a high-flex PS TKR regarding range of movement (ROM), 'feel' of the knee, pain and satisfaction, as well as during activity. A total of 24 female patients with bilateral osteoarthritis entered this prospective, blind randomised trial in which they received a high-flex PS TKR in one knee and a gender-specific high-flexion PS TKR in the other knee. At follow-up, patients were assessed clinically measuring ROM, and questioned about pain, satisfaction and daily 'feel' of each knee.

Finite element analysis of tibial fractures.

Introduction: Fractures of the tibial shaft are relatively common injuries. There are indications that tibial shaft fractures share characteristics in terms of site, type and local fracture mechanisms. In this study, we aimed to set up a mathematical, computer-based model using finite element analysis of the bones of the lower leg to examine if such a model is adequate for prediction of fracture locations and patterns.

Prevalence of malformations of the hip joint and their relationship to sex, groin pain, and risk of osteoarthritis: a population-based survey.

Background: Although the clinical consequences of femoroacetabular impingement have been well described, little is known about the prevalence of the anatomical malformations associated with this condition in the general population, the natural history of the condition, and the risk estimates for the development of osteoarthritis.

Methods: The study material was derived from a cross-sectional population-based radiographic and questionnaire database of 4151 individuals from the Copenhagen Osteoarthritis Substudy cohort between 1991 and 1994. The subjects were primarily white, and all were from the county of Østerbro, Copenhagen, Denmark.

Case definitions of knee osteoarthritis in 4,151 unselected subjects: relevance for epidemiological studies: the Copenhagen Osteoarthritis Study.

Introduction: The aims of the present study were threefold: to examine the distribution of knee joint osteoarthritis in a large, standardized radiological study; to examine the relationships between self reported knee pain and radiological OA; and to examine the natural history of radio-morphological change over age in individuals without radiological features of OA.

Materials And Methods: The Copenhagen Osteoarthritis Study - COS is a substudy of the Copenhagen City Heart Study, a longitudinal regional health survey. From the third inclusion of the CCHS (1992-1994) 4,151 subjects were selected for subsequent standardized radiography of the pelvis, the knees, the hands, the wrists, and the lumbar spine.

Predictors of length of stay and patient satisfaction after hip and knee replacement surgery: fast-track experience in 712 patients.

Background And Purpose: Very few studies have focused on patient characteristics that influence length of stay (LOS) in fast-track total hip (THR) and knee arthroplasty (TKR). The aim of this prospective study was to identify patient characteristics associated with LOS and patient satisfaction after total hip and knee replacement surgery.

Patients And Methods: Between September 2003 and December 2005, 712 consecutive, unselected patients (440 women) with a mean age of 69 (31-91) years were admitted for hip and knee replacement surgery at our specialized fast-track joint replacement unit.

The prevalence of cam-type deformity of the hip joint: a survey of 4151 subjects of the Copenhagen Osteoarthritis Study.

Background: Cam deformity is a preosteoarthritic malformation causing premature hip-joint degeneration. While the pathogenetic pathway from deformity to osteoarthrosis (OA) has been well established, almost nothing is known of the malformation's epidemiology.

Purpose: To determine the distribution of cam deformity in a large, unselected cohort from standardized anteroposterior (AP) pelvic radiographs.

A new radiological index for assessing asphericity of the femoral head in cam impingement.

Femoroacetabular cam impingement is thought to be a cause of premature osteoarthritis of the hip. The presence of cam malformation was determined in 2803 standardised anteroposterior (AP) pelvic radiographs from the Copenhagen Osteoarthritis Study by measuring the alpha (alpha) angle and the triangular index, a new measure of asphericity of the femoral head. In addition, the alpha-angle and the triangular index were assessed on the AP and lateral hip radiographs of 82 men and 82 women randomly selected from patients scheduled for total hip replacement (THR).

Low bone mineral density is associated with reduced hip joint space width in women: results from the Copenhagen Osteoarthritis Study.

Objective: Since estrogen receptors (ER-alpha/ER-beta) were identified in human chondrocytes, animal and experimental studies have demonstrated the importance of continued estrogen production for the integrity of articular cartilage. However, human epidemiological support of the hypothesis has been inconclusive. The present cross-sectional study investigated the relationship between reduced bone mineral density (BMD), as a surrogate parameter of endogenous estrogen status assessed by digital x-ray radiogrammetry, and reduced minimum hip joint space width (JSW).

Integrity of the lateral femoral wall in intertrochanteric hip fractures: an important predictor of a reoperation.

Background: Reoperations after intertrochanteric fractures are often necessitated by fracture displacement following mobilization of the patient. The biomechanical complexity of the fracture, the position of the implant, and the patient's characteristics are known to influence postoperative outcome. We investigated the importance of an intact lateral femoral wall as a factor in postoperative fracture displacement after fixation with a sliding compression hip screw.

Degenerative lumbar spondylolisthesis: an epidemiological perspective: the Copenhagen Osteoarthritis Study.

Study Design: A cross-sectional epidemiological survey of 4151 participants of the Copenhagen Osteoarthritis Study.

Objective: To identify prevalences and individual risk factors for degenerative lumbar spondylolisthesis.

Summary Of Background Data: The Copenhagen Osteoarthritis Study has registered health parameters since 1976.

Lumbar spondylolysis: a life long dynamic condition? A cross sectional survey of 4.151 adults.

Lumbar spondylolysis (LS) has been the subject of several studies focusing on adolescent athletes. Few, if any, studies have examined LS in the general population. Lysis of the pars interarticularis of the vertebra may be associated with slipping (olisthesis), or it may be stable.
