Multiomic analyses direct hypotheses for Creutzfeldt-Jakob disease risk genes.

Prions are assemblies of misfolded prion protein that cause several fatal and transmissible neurodegenerative diseases, with the most common phenotype in humans being sporadic Creutzfeldt-Jakob disease (sCJD). Aside from variation of the prion protein itself, molecular risk factors are not well understood. Prion and prion-like mechanisms are thought to underpin common neurodegenerative disorders meaning that the elucidation of mechanisms could have broad relevance.

Dynamics of troponins and 30-day mortality in hospitalized patients with pulmonary embolism.

Background: In patients with pulmonary embolism (PE), the impact of repeated troponin I or T (TnI/TnT) measurements remains unclear.

Methods: Using Danish national registries, we identified PE patients (≥18 years) hospitalized between 2013 and 2018 with initial TnI or TnT measurement within -1/+1 day from admission and >1 repeated measurement within three days. Trajectories of TnI and TnT were identified using latent class trajectory modeling.

Central nervous system involvement in Waldenström macroglobulinemia: a comparative population-based study of Bing-Neel syndrome and histological transformation.

Limited Benefit of Routine Clinical Follow-Up for Relapse Detection in Diffuse Large B-Cell Lymphoma Patients in Complete Remission Following First-Line Treatment.

Despite advances in treatment, approximately 15% of patients with diffuse large B-cell lymphoma (DLBCL) who achieve complete remission (CR) after first-line therapy will experience a relapse. However, there is no consensus on the optimal follow-up strategies for detecting relapse after achieving CR. This population-based study, based on the Danish Lymphoma Registry (LYFO), identified a total of 1634 patients diagnosed with DLBCL between 2010 and 2017, including 105 patients who achieved CR following first-line R-CHOP-like therapy and subsequently relapsed.

Exercise in early pregnancy among women with migraine: A hospital-based cross-sectional study.

Objective: Migraine is one of the most common pain disorders among women of childbearing age. While medical treatment might be necessary for some during pregnancy, non-pharmacological approaches, such as exercise, are generally recommended. We aimed to assess the association between migraine and exercise behaviours, adherence to the national recommendations for exercise, and the type of exercise undertaken during early pregnancy within a cohort of Danish women.
