BACKGROUND While some experimental and clinical research suggests that statins improve outcomes after severe infections, the evidence for pneumonia is conflicting. We examined whether preadmission statin use decreased risk of death, bacteremia, and pulmonary complications after pneumonia. METHODS We conducted a population-based cohort study of 29,900(More)
BACKGROUND Pneumococcal disease is a leading cause of morbidity and mortality worldwide. The aim of this study was to investigate the association between specific pneumococcal serotypes and mortality from invasive pneumococcal disease (IPD). METHODS AND FINDINGS In a nationwide population-based cohort study of IPD in Denmark during 1977-2007, 30-d(More)
RATIONALE Few population-based data are available regarding nontuberculous mycobacteria (NTM) pulmonary disease epidemiology and prognosis. OBJECTIVES To examine NTM pulmonary colonization incidence, disease incidence, and prognostic factors. METHODS All adults in Denmark with at least one NTM-positive pulmonary specimen during 1997 to 2008 were(More)
OBJECTIVE We sought to examine whether type 2 diabetes increases risk of death and complications following pneumonia and to assess the prognostic value of admission hyperglycemia. RESEARCH DESIGN AND METHODS This was a population-based cohort study of adults with a first-time hospitalization for pneumonia between 1997 and 2004 (n = 29,900) in northern(More)
OBJECTIVE To compare long-term glycemic control and safety of using insulin aspart (IAsp) with that of regular human insulin (HI). RESEARCH DESIGN AND METHODS This was a multicenter randomized open-label 6-month study (882 subjects) with a 6-month extension period (714 subjects) that enrolled subjects with type 1 diabetes. Subjects administered IAsp(More)
OBJECTIVES To investigate efficacy, safety, and impact on quality of sleep of desmopressin in the treatment of nocturia. METHODS Adults aged > or =18 yr with nocturia (> or =2 voids/night) received desmopressin tablets (0.1, 0.2, or 0.4 mg) during a 3-wk dose-titration period. Patients should show sufficient response during the dose-titration period (> or(More)
OBJECTIVE The aim of the study was to examine whether exposure to abacavir increases the risk for myocardial infarction (MI). DESIGN, SETTING AND SUBJECTS This was a prospective nationwide cohort study which included all Danish HIV-infected patients on highly active antiretroviral therapy (HAART) from 1995 to 2005 (N = 2952). Data on hospitalization for(More)
BACKGROUND Splenectomy has been associated with increased risk for infection. OBJECTIVE To assess the magnitude and duration of risk for hospital contact with infection associated with splenectomy. DESIGN Population-based cohort study. SETTING Denmark. PATIENTS All 3812 persons in Denmark who underwent splenectomy from 1996 to 2005. Splenectomized(More)
BACKGROUND To study whether use of β-blockers increases survival in patients with malignant melanoma because experimental data suggest that catecholamine hormones may be involved in stimulating the aggressiveness of malignant melanoma. METHODS A total of 4,179 patients diagnosed with malignant melanoma in Denmark with a median follow-up of 4.9 years and(More)
OBJECTIVE To examine whether diabetes is a risk factor for hospitalization with pneumonia and to assess the impact of A1C level on such risk. RESEARCH DESIGN AND METHODS In this population-based, case-control study we identified patients with a first-time pneumonia-related hospitalization between 1997 and 2005, using health care databases in northern(More)
