BACKGROUND: Hyponatremia has recently been associated with subsequent cancer risk. This population-based nationwide study assessed whether the diagnosis of hyponatremia can predict a cancer diagnosis within most common cancers. MATERIAL AND METHODS: Using Danish medical registries, we identified 16,220 patients with a first-time diagnosis of hyponatremia, without a cancer diagnosis, from January 2006 through November 2013. We quantified the relative risk of a subsequent cancer diagnosis by standardized incidence ratios (SIRs), comparing observed cancer incidence among patients diagnosed with hyponatremia to that expected, based on national cancer incidence during that period...

Infant respiratory distress syndrome (IRDS) may be complicated by intracerebral hemorrhage, a known trigger of epilepsy. However, few data exist on long term epilepsy risk following IRDS. We therefore examined the association between IRDS in preterm infants and childhood epilepsy. We conducted a population-based cohort study using individual-level data linkage among nationwide registries. All infants born at 32-36 weeks of gestation in 1978-2009 were identified in the Medical Birth Registry. We identified children with IRDS and those with epilepsy using the Danish National Patient Registry...

BACKGROUND: Infections are the leading cause of morbidity and mortality in children. Caesarean section as a potential risk factor for infection has recently gained interest. Delivery by caesarean section has increased greatly with non-medical reasons playing an increasing role. We aimed to analyze the association between mode of delivery and hospitalizations due to infection and symptoms of infection at home in early childhood. METHODS: A cohort study, based on the Odense Child Cohort, following infants from gestation until a mean age of 3...

BACKGROUND: Little information on the natural history of patients with localized NSCLC is available since many of the studies covering the subject lack information on pathological confirmation, staging procedures and comorbidity. No randomized studies have compared SBRT with no treatment for patients with localized NSCLC. The purpose of this study was to evaluate whether SBRT has influence on overall survival for patients with localized NSCLC and investigate the effect of baseline ventilatory lung function on overall survival...

Prosthetic joint infection (PJI) is a rare, but devastating complication following primary total hip arthroplasty (THA). As PJI is a rare event, large cohorts of patients are required in order to study this complication. National arthroplasty registers offer such large and unselected cohorts, but studies have shown that these registers - used alone - underestimate the incidence of PJI. The aim of this thesis was to estimate the incidence of PJI and the mortality risk following a PJI by combining data from the Danish Hip Arthroplasty Register (DHR), the National Register of Patients (NRP), the Microbiology Databases, the Civil Registration System, the medical records, the Danish National Prescription Registry and the Clinical Biochemistry Databases...

In patients with relapsed diffuse large B-cell lymphoma (DLBCL), high-dose chemotherapy followed by autologous stem cell transplantation (ASCT) is standard treatment. Here, we aim to identify factors associated with survival in patients undergoing ASCT. A total of 369 patients with relapsed DLBCL undergoing ASCT from 2000 to 2012 were identified in the Danish National Lymphoma Registry. Information on clinical and socioeconomic factors was obtained from medical records and national registries. Factors associated with survival were assessed using a Cox's proportional hazards model...

BACKGROUND: Many register studies make use of information about permanent nursing home residents. Statistics Denmark (StatD) identifies nursing home residents by two different indirect methods, one based on reports from the municipalities regarding home care in taken place in a nursing home, and the other based on an algorithm created by StatD. The aim of the present study was to validate StatD's nursing home register using dedicated administrative municipality records on individual nursing home residents as gold standard...

BACKGROUND AND AIMS: Inflammatory bowel disease (IBD) may be complicated by primary sclerosing cholangitis (PSC). We aimed to assess the characteristics of Danish PSC-IBD patients and to compare their prognosis with IBD patients without PSC. METHODS: A retrospective nationwide population-based cohort of 257 PSC-IBD patients was assessed through Danish national registries and manual scrutiny of patient files. RESULTS: For all PSC-IBD patients diagnosed after 1976 (n = 222) and 8231 IBD controls (ie, without PSC), the cumulative probability of resective surgery, liver transplantation, cancer, and survival from 1977 through 2011 was estimated and compared by log-rank test and Cox regression...
