We estimated the long-term socioeconomic consequences and health care costs of Neisseria meningitidis meningitis (NM). The prospective cohort study included Danish individuals with onset of NM in childhood and adolescence, diagnosed between 1980 and 2009. Health care costs and socioeconomic data were obtained from nationwide administrative and health registers. Two thousand nine hundred two patients were compared with 11,610 controls matched for age, gender, and other sociodemographic characteristics. In the follow-up analysis at the age of 30 years, 1028 patients were compared with 4452 controls...

INTRODUCTION: Separation from a parent during childhood has been linked with heightened longer-term violence risk, but it remains unclear how this relationship varies by gender, separation subgroup, and age at separation. This phenomenon was investigated by examining a wide array of child-parent separation scenarios. METHODS: National cohort study including individuals born in Denmark, 1971-1997 (N=1,346,772). Child-parent separation status was ascertained each year from birth to 15th birthday, using residential addresses from the Danish register...

BACKGROUND: Few studies have described recurrence rates after groin hernia repair in women. Our aim was to investigate if laparoscopic repair of primary groin hernias in women results in a lower reoperation rate for recurrence compared with open repairs. Furthermore, we wished to compare hernia subtypes at primary repair and reoperation. METHODS: This nationwide cohort study was reported according to the RECORD statement. We used prospectively collected data from the Danish Hernia Database to generate a cohort of females operated for a primary groin hernia from 1998 to 2017...

BACKGROUND: Excess mortality in individuals with severe mental illness (SMI) is often explained by physical comorbidity and suboptimal healthcare. Cancer is a prevalent cause of death, and tumour stage at diagnosis is a strong predictor of mortality. We aimed to study cancer incidence, disease stage at diagnosis and subsequent mortality in individuals with SMI compared to individuals without SMI. METHODS: The entire Danish population was followed in 1978-2013 using nationwide registries...

BACKGROUND: Although the pathogenic nature of copy number variants (CNVs) on chromosome 22q11.2 has been recognised for decades, unbiased estimates of their population prevalence, mortality, disease risks, and diagnostic trajectories are absent. We aimed to provide the true population prevalence of 22q11.2 CNVs and associated trajectory of disease risk and mortality by use of the unbiased, representative Danish iPSYCH population case cohort. METHODS: This case-cohort study was done on a population of 86 189 individuals selected from the iPSYCH case cohort of 1 472 762 singletons born in Denmark between May 1, 1981, and Dec 31, 2005, who have a known mother from the Danish Civil Registration System, were residents in Denmark at 1 year of age, and enrolled in the iPSYCH Initiative...

BACKGROUND: Prior studies indicate that stratified care for low back pain results in better clinical outcome and reduced costs in healthcare compared to current practice. Stratified care may be associated with clinical benefits for patients with low back pain at a lower cost, but evidence is sparse. Hence this study aims to evaluate the clinical effects and cost-effectiveness of stratified care in patients with non-specific low back pain compared to current practice. METHODS/DESIGN: The study is a two-armed randomised controlled trial in primary care in the Regions of Southern and Central Denmark (2...
