Impact of the intensified follow-up procedure of patients lost to 6-month follow-up after an intensive smoking and nicotine cessation intervention in practice: a cohort study.

Background: Post-intervention follow-up is challenging in research and practice. In tobacco reports, patients with missing follow-up were considered smokers. Based on patient and staff preferences, an add-on intensified follow-up procedure after intensive tobacco and nicotine cessation interventions was developed.

The Concept of a Large Group-Based Approach for Intensive Smoking Cessation: The Gold Standard Program (GSP).

In this study, the effect of the intensive "Quitter" intervention for smoking cessation was examined and compared to the standardized intensive intervention used in Denmark. The Quitter intervention, based on the Gold Standard Program (Q-GSP), involves large groups of approximately 70 participants, while the standardized GSP typically involves groups of 10-15 participants. In total, 105 and 14,289 smokers participated in the Q-GSP and the standardized GSP, respectively, between 2022 and 2023.

Development and internal validation of a diagnostic prediction model for psoriasis severity.

Background: While administrative health records such as national registries may be useful data sources to study the epidemiology of psoriasis, they do not generally contain information on disease severity.

Objectives: To develop a diagnostic model to distinguish psoriasis severity based on administrative register data.

Method: We conducted a retrospective registry-based cohort study using the Danish Skin Cohort linked with the Danish national registries.

Childhood asthma is associated with development of type 1 diabetes and inflammatory bowel diseases: a Danish nationwide registry study.

Asthma and autoimmune disorders might be affected by opposing immune mechanisms, T helper cells type 2 (Th2) and T helper cells type 1 (Th1) immunity, respectively. Knowledge on comorbidity can increase understanding of the underlying etiologies. We aim to examine the association between childhood asthma and subsequent risk of type 1 diabetes (T1D) and inflammatory bowel diseases (IBD) in Danish children.

Incidence, Risk Factors, and Consequences of Human Alphaherpesvirus Infections in Patients With Psoriasis Who Initiate Methotrexate or Biologic Agents.

Background: Immunosuppressive agents may increase the risk of infections with human alphaherpesviruses.

Methods: We included all adult patients with moderate to severe psoriasis who initiated methotrexate (MTX) or biologic agents in a retrospective cohort study. An episode of alphaherpesviruses infection was defined as filling a prescription for systemic acyclovir, valacyclovir, or famciclovir.
