The Danish Hip Arthroscopy Registry (DHAR) was initiated in January 2012 as a web-based prospective registry. The purpose of this study was to evaluate and report the first registry based outcome data of a national population with radiological and clinical femoroacetabular impingement (FAI) undergoing hip arthroscopic treatment. Our primary hypothesis was that patients undergoing hip arthroscopy would improve significantly in pain, quality of life and sports related outcome measurements in Patient Related Outcome Measures (PROM)...

BACKGROUND AND PURPOSE: Double-blind randomized studies on the effects of oral postmenopausal hormone therapies were stopped mainly because of increased risk of stroke. We aimed to assess the risk of all strokes and various subtypes associated with hormone therapy and explore the influence of regimens and routes of administration. METHODS: A national historical cohort of women aged 51 to 70 years from 1995 to 2010 was established by linking 5 Danish registries. The National Registry of Medicinal Product Statistics provided information on hormone therapy exposure and the National Patient or Cause of Death Registries supplied data regarding stroke diagnoses (ischemic/hemorrhagic/subarachnoid hemorrhage)...

BACKGROUND: Hip dislocation is one of the most common postoperative complications after total hip arthroplasty (THA). Potential contributors include patient- and surgical-related factors. We performed a retrospective cohort study to identify risk factors for postoperative dislocation in patients receiving THA via the posterolateral approach. METHODS: We assessed 1326 consecutive primary THAs performed between 2010 and 2015. Patient information was documented, and plain radiographic films were used to evaluate cup positioning, hip offset, and hip length change...

INTRODUCTION: The femoroacetabular impingement (FAI) morphology is associated with specific cartilage lesions, which are suspected to be early stages of the osteoarthritic development, which can be the end result of FAI. The cartilage status of FAI afflicted hip joints at the time of arthroscopic management is not fully elucidated. This study from the Danish Hip Arthroscopy Registry (DHAR) will try to show data on the cartilage status from a large cohort. Data from a national registry potentially represent large amounts of population-based epidemiological information from multiple centres and surgeons...

BACKGROUND: Use of oral anticoagulation therapy in patients with atrial fibrillation (AF) involves a trade-off between a reduced risk of ischemic stroke and an increased risk of bleeding events. Different anticoagulation therapies have different safety profiles and data on the societal costs of both ischemic stroke and bleeding events are necessary for assessing the cost-effectiveness and budgetary impact of different treatment options. To our knowledge, no previous studies have estimated the societal costs of bleeding events in patients with AF...

Prior studies have yielded inconsistent evidence regarding the association between formaldehyde exposure and amyotrophic lateral sclerosis (ALS). We conducted a population case-control study in the Danish National Registries on the relationship between occupationally-derived formaldehyde exposure and ALS. Occupational history was obtained from a comprehensive and prospectively recorded pension database of all paid work in Denmark since 1964, and was linked to a job-exposure matrix to derive individual exposure estimates...

Background: The 5-lipoxygenase pathway has been linked to atherothrombotic disease, and a functional tandem repeat polymorphism in the arachidonate lipoxygenase-5 (ALOX-5) gene has been associated with the risk of myocardial infarction (MI). Interestingly, 2 studies have reported an interaction between dietary intakes of the ALOX-5 substrates, arachidonic acid (AA) and eicosapentaenoic acid (EPA), and genotype.Objective: We investigated whether the interactions between the ALOX-5 tandem repeat polymorphism (rs59439148) and adipose tissue AA and EPA were associated with incident MI...

Community-acquired Staphylococcus aureus bacteremia (CA-SAB) is a serious infection with detrimental clinical effects. Chronic diseases constitute some of the most important risk and prognostic factors for CA-SAB. The prevalence of diabetes and chronic heart failure (CHF) is rapidly increasing on a global scale, nevertheless, there are few data available specifically elucidating the influence of these chronic conditions on CA-SAB risk and outcome. Therefore, to extend the current knowledge, we aimed to I) elucidate the impact of different definitions of healthcare-associated (HCA) infection on the prevalence of HCA-SAB, patient characteristics, and mortality, II) to investigate whether diabetes is a risk factor for CA-SAB, III) to ascertain the prognostic influence of diabetes on CA-SAB outcome, and IV) to investigate the influence of CHF on mortality in patients with CA-SAB...

An abdominal aortic aneurysm (AAA) is an enlargement of the abdominal aorta. It is a common disease in the elderly, with a prevalence of 1-5%. An AAA is normally asymptomatic, and the diagnosis is often incidental, identified when a patient is examined for other conditions. The major risk of having an AAA is sudden rupture and death caused by massive hemorrhaging. As rupture risk increases with increasing AAA diameter, the current management strategies include regular imaging surveillance and elective repair before rupture occurs...

PURPOSE: We aimed to evaluate the excess direct and indirect costs associated with epilepsy. METHODS: From the Danish National Patient Registry (1998-2013), we identified people within all ages with an epilepsy diagnosis and matched them to control individuals. Additionally, partners of people with epilepsy were identified, who were compared with control partners. Direct costs included frequencies and costs of hospitalizations and weighted outpatient use according to diagnosis-related group, and specific outpatient costs based on data from the Danish Ministry of Health...

BACKGROUND: Diagnoses of peptic ulcer are registered in the Danish National Patient Registry (DNPR) for administrative as well as research purposes, but it is unknown whether the coding validity depends on the location of the ulcer. OBJECTIVE: To validate the International Classification of Diseases, 10(th) revision diagnosis codes of peptic ulcer in the DNPR by estimating positive predictive values (PPVs) for gastric and duodenal ulcer diagnoses. METHODS: We identified all patients registered with a hospital discharge diagnosis of peptic ulcer from Aarhus University Hospital, Denmark, in 1995-2006...

BACKGROUND: Women with bipolar disorder are at high risk for relapse/recurrence postpartum. Among all mood stabilizers, lithium has the largest evidence base for efficacy in the peripartum period, but lamotrigine is increasingly prescribed for bipolar spectrum disorders during pregnancy. The aim of this study was to investigate whether lamotrigine use during pregnancy is as effective as lithium in the prevention of severe episodes postpartum. METHODS: Danish national registries were used to identify pregnancies of women with a diagnosis of bipolar spectrum disorders at the time of conception who used lamotrigine or lithium during pregnancy...

Semen quality is suggested to be a biological marker of long-term morbidity and mortality; however, few studies have been conducted on this subject. We identified 5,785 men seen for infertility in Frederiksberg Hospital, Denmark from 1977-2010, and 4,712 men were followed in the Danish National Patient Registry until first hospitalization, death or end of the study. We classified patients according to all hospitalizations and the presence of cardiovascular disease, diabetes, testicular and prostate cancer. We found a clear association between sperm concentration below 15 mill/mL and all-cause hospitalizations, 50% (95% CI: 1...
